Ask HN: What is your money-making side project outside programming? - <AUTHOR> Always wondered this. Sometimes I feel the need to do something else outside my field, and possibly get some money out of it. <comment><USER2> Breville coffee grinders are impossible to get internal parts for. I designed a 3D printed upgrade for the main wear-part in their BCG800XL and BCG600SIL Grinders.

The storefront is through ShapeWays[1] and I use iFixit[2],[3] to drive the traffic. It passively makes enough to cover my own coffee needs forever. I spend about 20 minutes per month fielding questions. This all happened because my grinder failed and I could not get parts.

<comment><USER3> I recently ordered a part for my daughters dresser drawer - the Kenlin Rite- TrackII, and paid $12 for four including shipping. 6 to 7 years ago I paid $68 for a single part. To my surprise when I opened my recent plastic mailer envelope, I discovered it was a 3D printed piece. Any idea how one can 3d scan a part for exact copy?

<comment><USER4> They make full on 3d scanners but most parts do not need "3d scanning" so much as they need a few minutes in the hand of someone with a caliper and a sketch pad.

</comment></comment></comment><comment><USER5> I buy cars, repair them and recondition them to my level of satisfaction, and send them back out the door, typically targeting 55-65 year olds. I focus mostly on entry level luxury crossovers around 7 to 10 years old, though starting to also do hybrids since there's more profit in it since everyone is seemingly allergic to batteries and pack replacement/rebuilds.

Parts are cheap, I listen to music or a podcast, I do all the "PITA" repairs (replacing wheel bearings, ball joints, tie rods, full brake service) that are really just labor in terms of professional repair cost, perform additional rust prevention, and for sale it goes when I feel a new grandma or grandpa would never give a hesitation to load it up with all their grandkids. They also see a very thorough interior cleaning, and a full exterior detail (including paint correction when required).

It has bought every very nice tool I could ever want, most are 20-30 hours of labor including acquisition, and I'm at the point where I have repeat customers (the put a 2nd alongside the first) and have direct referrals. Now the profit mostly goes towards putting a 2nd interesting car in the garage, and some towards moving up the ladder to try to earn more per vehicle.

Selling cars isn't bad when you don't have employees to pay, and it lets you sell really high quality stuff. I keep thinking of how much I couldn't justify doing, and how much my product standards would suffer if I had to pay help.

<comment><USER6> Can you make YouTube videos about it? I watch Chris Fix all the time, not for educational purpose (I don't own a car), but because they are so freaking satisfying to watch. Seeing things go from 'meh' to 'wow.'

<comment><USER5> I think the unfortunate reality of ChrisFix is to make videos at that level of quality... takes real time and effort -- plus a vehicle that merits actual work he's not done a video on yet. Hence he only puts out one or two a month, but they're of an extraordinarily high quality, which is evident in his sub numbers and view count.

I've considered making videos, but the reality at the moment is there's not yet the time to do it to my level of quality. At least not yet.

<comment><USER7> There are a few mechanics who stream on twitch... however that does require some level of interaction and distraction which may just be annoying to you, but doesn't require the post processing. However it's a decent sales pitch and if you do enjoy interactive with people and networking it can be pretty good.

I'd love to see your shop or even just time lapses. I really enjoy watching cnc and hand builds on youtube. It's very helpful to watch these to see what's really involved in say pulling the front end off of a mini-cooper.

<comment><USER5> It would be impossible to hit my target level of quality live, without heavy investment in the environment, lightning, video equipment, and honestly the help of someone when filming. If I can't hit my own targets, I just don't do something.

The videos would also be too long. Part of why ChrisFix is so well known is he has high-quality, edited, to-the-point content that packs everything into a concise high-quality video. I could not do that on Twitch without great expense, lots of advance planning, and helping hands.

<comment><USER7> Sure, I'm not going trying tell you what to do. You're the content creator, you need to do what you feel works or you won't make good content.

They're 2 different things, eg there's a huge difference between say ChrisFX and a twitch stream for a mechanic, though they're both basically build logs at the end of the day.

Twitch is definitely more the low overhead mass content version of content. Similar to the Howard Stern Show, or Car Talk, as opposed to The Grand Tour. Thousands of hours of contents as opposed to hundreds, or 10s.

I was just pointing out there's a market for the mass quantity content.

It's actually one of the things I DONT like about the produced car rebuild shows, they often edit out stuff just to make it entertaining to everyone, where I'm wanting to watch just to see the whole thing and the techniques. Much more like slow tv. I'm totally happy to skip through parts I don't care about.

I conduct a form of ethnography, embedding myself in the lives of consumers the way Margaret Mead did among Samoans. I interviews my subjects and the people around them, itemizing the contents of their home (photographing and videotaping), and accompany them as they progress through their day. Then I sift the resulting information for weeks, even months, looking for connections and telltale behaviors.

The service is used mostly by founders for small businesses and startups. I takes questions about sales figures and product lines and reconfigures them into questions about worlds, the context in which people unthinkingly live their everyday lives. The idea is that examining the beliefs and unconscious biases that people have will eventually yield profitable insights for these businesses.

So far, I've done market entry for a few Chinese companies into Japanese market, helped indie game design company launch a successful game, a boutique lingerie shop launch a new summer line, street musicians, and a few cafes and bars.

I do this on the side with hopes to go full time into it soon.

<comment><USER9> When I look up MMR I get "measles, mumps, and rubella." I assume that isn't what you're referring to.

<comment><USER10> I think the parent meant "MRR" \-- monthly recurring revenue.

</comment></comment></comment><comment><USER11> I established DamnInteresting.com in 2005, a place where myself and handful of others produce original long-form non-fiction in article and podcast form. Despite plenty of traffic, it didn't reach the break-even point for several years, because I despise advertisements and I refused to add them to my site. I funded the project in other ways, such as donations, publishing a book, licensing content, etc.

Nowadays it _still_ only earns a little every month, but that's mostly owing to a rise in expenses (e.g., I pay the contributors more). But profit is secondary for me, my primary motive is to have an excuse to research and write this stuff, and for intelligent people to consume it.

<comment><USER12> This looks neat. I'll be sure to read a few articles from here.

Why the curated section though? I think it distracts to have links to articles from NYTime or Wired on the side.

<comment><USER11> It's a long story, but the short version goes something like this:

At first we worked our cabooses off to publish new original content several times per month. This proved unsustainable, partially because we were becoming more ambitious with our work, but especially owing to stressors that had arisen in my personal life, and I burned out.

I spent a year-long hiatus putting things right, and when we resumed our writing, it was with the understanding that we were switching to a marathon- not-a-sprint publication schedule. The curated column arose to fill in the gaps between our in-house writings. Nowadays many readers specifically visit us for the links, so we feel duty-bound to persist.

<comment><USER13> I'd just like to thank you for this. I love all your content and have supported the site in the past. But I especially love the curated section - it's better than recommendations I get from other places like Pocket or Instapaper.

Thank you for doing this. Your site is a treasure.

I'm an avid saxophone player and am taking evening classes in theory, so I made this to solve a problem that I myself had. Nothing else like it on the market!

Every part of this notebook is automatically generated with a bunch of python scripts: the cover design, the interior, the line placement, the margins. The program basically spits out a PDF which I can then send to print shops (which is the hardest part of the whole thing!)

The product is good, people like it, and the hardest part for me right now is sales - trying to get stores to carry it, or get traffic to the site to drive sales! If you know anyone who might be interested...

edit: Okay I've opportunistically created a coupon code THANKSHN for 10% off.

<comment><USER15> First, great job! Second, I'm confused. When I used to play music, I remember buying staff music pads at a low cost. A quick check of Amazon shows a bunch of staff pads for sale. What am I missing? Is it the combination of staff and notebook pages in the same book? Or do you use higher quality paper (e.g. are you the moleskin of music staff paper?) Just curious.

<comment><USER14> Elevator pitch:

\- combination of staff paper and college-ruled lines

\- perforated to easily tear out pages

\- three-hole punched

\- decent quality paper, binding, cover material

You'll find that there's surprisingly nothing like it on Amazon! My inspiration was those cheap Mead spiral notebooks - incredibly functional.

</comment></comment></comment><comment><USER16> Two things, both of which I stumbled into accidentally -

I make lots of jellies once the berries in the garden are ripe; I bought a house in a rural area a few years ago and it came with loads of berries. Might as well put them to use.

It is all done manually (in part because it is meant to be a diversion from my engineering job) - red- and blackcurrant and gooseberries mostly. Last year the harvest was some 1200 4oz glasses of jelly - some 1150 more than my family consumes. Sells by word of mouth.

Also, as my mother is quite into weaving tapestry and it was hard to find the exact hues she wanted for her yarns, I started dyeing for her, using traditional colouring. Turned out there was a (veee-eeery small!) market for that kind of thing, and I now make small batches for some 30-35 weavers. Again, fully manual as the idea is to do something completely different from my full-time job.

<comment><USER17> This is a true break from tech. Go for it.

<comment><USER16> -Oh, I'd go nuts if I did either of the above full-time; however it serves as a wonderful diversion and it is great to do something which produces tangible results.

It helps being an engineer, too - I've found (much to my surprise) that keeping detailed notes to ensure repeatable results is quite rare in both pastimes.

I thought everybody kept log books! :)

</comment></comment></comment><comment><USER18> I've written a couple of books that sell on Amazon and Apple iBooks - it takes zero minutes per month work for me, but brings a nice little side income. I won't get rich, but it's nice to have the money come in for doing nothing after I hit the "publish" button. Even the printed books cost nothing.

I'm about to hit publish on a photo coffee-table book from my three years around Africa, and I'll write an Africa guide book and The Road Chose Me Vol 2 in the next 12-18 months.

* The Road Chose Me Volume 1: Two years and 40,000 miles from Alaksa to Argentina ([https://amzn.to/2vfCYvn](https://amzn.to/2vfCYvn))

Stories and lessons from two years driving my Jeep Wrangler down the Pan- American Highway

* Work Less to Live Your Dreams: A practical guide to saving money and living your dreams ([https://amzn.to/2OD6UtA](https://amzn.to/2OD6UtA))

An eBook about how exactly I can afford to take years off work to do what I want and live my dreams.

* West Africa Myths, Misconceptions and Misnomers ([https://amzn.to/2veyQMt](https://amzn.to/2veyQMt))

After driving the length of the continent, I collected a bunch of information that is extremely helpful to anyone else thinking of doing similar. The vast majority of the Western Worlds "knowledge" of West Africa is so out of date it's useless. My book is from info I learned during my drip from mid 2016 to late 2017, so it's relevant

<comment><USER19> Any hints about publishing a coffee table photo book? I have a photo journalism project in mind.

<comment><AUTHOR> Check PastBook.com I made a coffee table book from my NYC trip and it's super cool. Stefano, the CEO, is a very close friend of mine, but I can guarantee on the quality of the products.

</comment></comment></comment><comment><USER20> I taught myself circuit board design and found a niche market that I designed a few products for that sold like gangbusters with zero marketing for a few years until the market cooled off and low cost knock offs started entering the market.

I also found that you could use the same CAD program that I learned to design PCB's to draw outlines to cut out on the laser CNC machine at the local maker space. I ended up finding a niche on ebay building open air computer cases. Because of the economics of shipping large items from overseas and the low cost of the materials I was using I was able to under cut the imports on price by like 60% and still make a nice amount of money on a $/ hour basis.

In hind sight the best way to find these kinds of opportunities is not to be looking for them. You really just need to get a really deep understanding of a hobby or industry or market that interests you in some way and once you have that then these sorts of things kind of pop out of the woodwork.

<comment><USER21> This is super cool!

> I taught myself circuit board design and found a niche market that I > designed a few products for that sold like gangbusters with zero marketing > for a few years until the market cooled off and low cost knock offs started > entering the market.

Can you elaborate a bit? Did you teach yourself literal circuit board design (but already had a background in electronics/hardware)? Or did you start from scratch and learn how to design an electronic circuit?

What was the niche (broadly?)

> In hind sight the best way to find these kinds of opportunities is not to be > looking for them. You really just need to get a really deep understanding of > a hobby or industry or market that interests you in some way and once you > have that then these sorts of things kind of pop out of the woodwork.

1000% agree. The single best way to find an idea is to be seriously and deeply involved in a hobby/area of interest. There are so many ideas out there screaming you in the face.

<comment><USER20> It was a bit of both, My degree is in CS, I only took one EE/hardware class in school that was more about programming CPLDs than anything else. These days really all you need to know math wise to build simple stuff is V=IR and P=IV, things everyone learns in high school physics class. Everything else you can usually get by looking at the reference circuits in data sheets or looking it up as you go. The hardest part for me was finding the time to get over the learning curve of the PCB design software, in my case I learned EagleCAD. After I did that and formed good habits with how I used the software I now able to do some pretty complex stuff. The limiting factor now is probably that my ambition has outgrown the software I learned.

The niche was building adapters for old server power supplies so you can re- purpose them for use as general purpose 12 Volt power supplies. It was a thing in the RC community for a while to charge batteries but it got really big in the 2014 - 2017 time frame due to the Bitcoin mining industry needing low cost high wattage PSUs.

</comment></comment></comment><comment><USER22> About 10 years ago and ten years into my career, I had been working and stayed at the same job way too long and both my salary and career stagnated.

I had two part time money making side projects. I was a part time fitness instructor and had some rental real estate.

Teaching fitness classes was fun, I made a lot of friends, and it gave me a release valve from working at a computer all day. Real estate was a headache.

Around 2008 -2011, a few things happened. The real estate market crashed and I did a few "strategic defaults", I realized I could make a lot more by getting better at software engineering and job hopping, and I got married and gained a wife and two (step) children.

I gave up all of my side projects, concentrated on my career, started building a network of recruiters, former coworkers, and former managers and doubled my income over the next 8 years (not bragging, I still make about the average of principal engineer/architect/team lead in my area).

Even looking over the next two to five years, I should be able to increase my income by 50% (working for local companies) to well over 100% (if I can get into Amazon) as some type of cloud consultant, "digital transformation consultant", or "Architect". The only thing stopping me now is the travel requirements. I want to wait until my youngest completes high school.

But, that means I can't juggle my job, family commitments, working out, filling in some technical gaps _and_ a side job/business.

So no side business.

<comment><USER23> Thanks, this is insightful. Sounds like the opportunity cost of a side business isn't worth it for you right?

<comment><USER24> to;dr -- Never devalue your personal time. If you can, monetize your hobbies that you'd be doing anyway.

I don't have a side-hustle yet, but I'm working on one. As you pointed out, there's an opportunity cost to a side-business. I'm working on a scheme to monetize a hobby; make money off something I'd be doing anyway. I'm just over 10 years into my career, recently married with a teenage step-child. My family-time or my "down-time" is very precious to me. During our wedding, we got some beautiful wedding save-the-dates off Etsy. They were water-color paintings. But then we needed additional stationary: invitations, menus, seating charts, table signs, a gobo (wtf is a gobo??), etc.... I ended up using photoshop to make all of the other stationary and graphics myself based off the initial Etsy save-the-dates (it was important to me that the fonts & colors matched on everything). My wife loves to paint water-colors, and I'm into photography & graphic-design. I'm working on a side hustle to do wedding invites and similar stationary on Etsy based off her paintings and my photography & graphic-design skills. These are (mostly) activities we'll do anyway. So... make some stationary templates once, throw them up on Etsy, and if people buy them GREAT, if not then no loss.

<comment><USER25> For me, monetizing a hobby is a quick way to start hating it. Unless you really want as much money as you can get, you probably shouldn't monetize all of your hobbies.

</comment></comment></comment></comment><comment><USER26> I raise bees and sell the honey. Good for a few thousand a year and the money makes up for the stings. I have a couple of dozen chickens and sell the eggs, but this makes very little money since eggs are so cheap in the super market. It pays for the feed and that's it. I wrote an Amazon book on how to play harmonica in the style of Sonny Boy Williamson II that sells steady and makes me beer money. I sell a couple of my Science Fiction short story collections on Amazon. "Error Message Eyes" and "Frogs in Aspic", but after a good first year they sell only a couple of copies a month. I sell four or five Science Fiction stories a year, but only occasionally do I get pro rates. It's nice to see your name in print, though.

<comment><USER27> This one sounds fun - just out of curiosity, how many times a year do you get stung?

<comment><USER26> How many times a day? I usually can't get away from being around the hives without a sting. Luckily the bees are usually calm and a honey bee sting is like a bad mosquito bite. It is not like a wasp or hornet sting.

If I open the hive without gloves and veil, I can get stung, but not always. If I have to "work the hive" I have to go full bee suit to prevent being stung.

If you can't handle being stung then raising bees is not a good hobby. If you can stand it, honey is like gold, and people will hound you for it.

</comment></comment></comment><comment><USER28> Not really a productive venture, but it was profitable. I used a 3% cashback credit card on a financial company's money sending service with no fees, and sent my sister $3,500 every two days. She'd then eventually pay me back through bank ACH (also free). Then I'd pay off my credit card every week so my credit balance remained low. Made about $1,500 a month for a year, before they stopped giving cashback for transfers.

<comment><USER29> This seems a tad unethical

<comment><USER28> I was actually thinking about ethics a lot while I was doing this little project. By ethics do you mean morals or something different? What framework would you suggest for determining the ethics/morals of doing something like this, where we're playing by the legal rules by trying to optimize for our own benefit?

<comment><USER30> Think about it like this. The logical conclusion of people acting like you did is that credit card issuers increase interest rates to make up for their losses. That makes life worse for everyone but the people exploiting the loophole. You're no different from the people who exaggerate their losses to insurance companies in order to claim extra insurance money. Because of them, premiums have gone up. You might see yourself as some kind of Robinhood figure, but ultimately it's going to be the other people participating in your network that suffer.

<comment><USER28> Thanks for the reply. There is a clear difference between claiming extra insurance money and what I'm doing: lying to get more insurance money is fraud, while what I'm doing is exactly what the service is intended for (sending money to others for free).

But using your framework of, "if everyone did this, how would this affect the business and others using the business," then I (and many others) are doing a lot of other unethical things. Ad blocking and card counting (in blackjack) clearly would be deemed unethical under this criteria, but here's a bunch of other more tangible examples.

There's a popular pastry place that has 50% off sales on Sunday afternoon because they are closing Monday so they sell the remaining stock at a significant discount before close. I only go there on Sunday afternoons, but if everyone did that, then the prices would go up for all.

Another thing I do is using the books, video games, movies, and streaming services offered by my library and never buy any real media. But if everyone did this, then bookstores, theaters, and streaming companies would go bankrupt.

<comment><USER31> You may be following the letter of the law but not the spirit of the law.

The cashback was created as an incentive, you found a way to exploit the business model for personal gain in ways that can have an impact on others ability to enjoy the system while having a material impact on the provider of the service. Most in your position will say "but I am only a small piece of the cog" however, if a small minority starts to think the same way, it can have a real impact on a variety of things, including trust between parties.

Everyone tries to rationalize their actions, whether it is or becomes socially acceptable is another matter.

<comment><USER22> Well, everyone that takes a VC subsidized ride on Uber is also having a negative impact on their business. If the business makes rules that are unsustainable for their business, it's their fault. They could very easily set limits to curb abuse.

<comment><USER32> Uber are obviously trying to get people to use their service. If using their service is bad for them, that's their fault because they were deliberately trying to encourage a behaviour that was detrimental to their business.

That is different from finding a way through the rules which is clearly unintended.

<comment><USER33> You don't think offering cash back is a way to get people to use their service?

<comment><USER32> Of course it is. Do you really think that they wanted to pay eighteen thousand dollars for someone to rapidly transfer money back and forth?

<comment><USER22> Hopefully they had the financial wherewithal to model outliers in their profit model.

We did a little twist on the business model. Starbucks sells nice places to sit down. We sold drugs. The model, from logo design to promotions, was designed to create a habit loop where people would get their morning coffee from us.

It was so profitable that I seriously considered making it my full time career, expanding cafes all over the country. The only thing that changed my mind was 1) the startup boom 2) dealing with minimum wage workers is extremely depressing. The tech industry has its abundance, whereas with food and drinks, it was clear that income was limited and had to be managed carefully.

<comment><USER35> > We sold drugs.

Drugs? As in prescription drugs?

<comment><USER36> No, as in mind altering drugs: coffee.

</comment></comment></comment><comment><USER37> In addition to regular index fund investing I trade options sometimes. Been doing it for about 6 months now and I'm up about 90%. I _am_ a lot more conservative than most options gamblers but it's still pretty risky. I put all my gains into high earnings stocks (currently buying STX and LYB) and at this point since I've almost doubled my principal, I could lose basically all my money currently allocated to options and have only lost 10% from my initial investment. I do it somewhat as a way to earn money but mostly for the experience, since I think it helps me learn a lot about how equities are priced and how the market reacts to news and macro events.

Rather than continually making bets just for the sake of making bets I only make trades when I think a stock overreacted to bearish news (meaning it's likely to rebound to its old price given that the business' fundamentals are unaffected), was oversold due to underperformance of other stocks traded alongside it, or is greatly overvalued due to some irrational hype (Lyft and most canadian weed stocks). And I sell quickly if the option loses a lot of its value or if the option greatly appreciates to lock in profits and limit losses.

<comment><USER38> This is great. Any good resources to learn informed investing?

<comment><USER37> For options? I guess [http://www.optionstrading.org/strategies/a-z- list/](http://www.optionstrading.org/strategies/a-z-list/) is a good place to start. One way people just starting out with options fuck up is that they take out positions with a very large upside but also very high risk to ruin. It's like going to a roulette table basically. If you take out more complex positions you can limit your downside, make money on sideways movements, etc. You can also limit downside by setting up orders to sell above/below certain values too.

I read some finance textbook when I was just starting out, I think it was "introduction to derivatives and risk management". That helped too. It's a good, gentle introduction to derivatives and you can skip most of it unless you want to work for an investment bank.

I think the best way to learn is to just watch stocks overtime, and read up on the news relevant to them. That's really why I play with options, it keeps me plugged into following the movements of a bunch of different stocks, so I learn a lot about what makes them behave in certain ways. Definitely stay away from paid classes on investing or trading, those are almost all scams - if a "successful trader" has to teach paid classes they're not actually successful. And re: my strategy of trying to identify short term movements that make something under/over-valued and hoping it will correct, just realize that sometimes the market can stay irrational longer than you can remain solvent, and sometimes you just need to take the loss and get out.

One more thing I forgot. When I refer to "news" I mean real news. A lot of financial news websites are complete bot-written vacuous garbage. Real news is things like deals happening or falling through, large orders, interest rates, lawsuits, recalls, earnings, trade deals, etc.

<comment><USER39> I started playing with Options recently too. I read many books/blogs but "Trading Options Greeks: How Time, Volatility, and Other Pricing Factors Drive Profits" seems to be most helpful. Not sure if it is really a beginners book or not.

I mostly stick with SPY and it keeps climbing. I just buy 30-45 days out calls that are slightly out of money. Usually sell them at 20-30% profits with in a few days.

Of course, it is only 1-2% of my regular investments in index funds. Too risky to put any real money in options.

<comment><USER37> It's less than 5% of my total investments too (I am young and don't have tons of money yet). I will check out that book, I've already got a good intuition for the greeks but don't know much theory on how to actually price them in if I were to sell options.

The thing I'd be worried about with medium term SPY calls is that you will be completely wiped out by a recession. Or even if a correction happened like in December and didn't rebound fast enough. Of course during a bull market that's a fine strategy (as long as theta/IV don't eat any potential profits) , and if you are socking away your gains it's probably fine. But if you are just growing your options allocation by 50% every couple weeks and then throwing it all back into the same position, eventually your double or nothing will come up nothing. Just something to consider

</comment></comment></comment></comment></comment><comment><USER40> For the past few years I've been buying, renovating, and selling small-ish houses. My dad was a contractor growing up so I picked up most of the necessary skills helping him out during middle and high school. I mostly work on weekends and holidays which makes it a bit slow going, but I've made a reasonable amount of money. Even if the money was worse I would still probably do it, I really enjoy both the physical aspects of the work and seeing a house go from a beat up old husk to a shiny new place! I have to contract out some of the work (electrical mostly) because I'm not a certified electrician, but otherwise it is a one man show.

<comment><USER41> Would it make more sense to rent them out rather than sell?

<comment><USER40> I would then have to deal with finding tenants, property maintenance issues, etc (or pay someone to do this), which is more than I really want to do right now. At that point I would be closer to a full time landlord, not a full-time software engineer who enjoys working on houses on the side!

<comment><USER41> Run the numbers and compare in your next sale. As a rule of thumb if you can get 1% of the sale price per month in rent you're doing awesome.

And a good property manager should take away 95% of the hassle.

<comment><USER42> You're saying that if the house sold for $500,000, you should keep it if you can rent it for $5,000 / month or more?

I've heard of 5% of 1/12th of the projected sale price, which seems more realistic.

<comment><USER41> Yes $5000/month would make that a great property. Look up the one percent rule.

For many older and rare cars it's usually no longer possible (or desired) to replace broken electronic components such as the engine or transmission controller. So owners contact me to have the part repaired instead of replacing it.

The repairs are usually not that challenging for me, and it won't make me rich, but it's a great way for me to clear my head from challenges with my tech startup. It also gives me access to some very rare and expensive cars. Obviously you need to test drive the car if you just fixed the ECU ;-)

<comment><USER44> That sounds really interesting. By repairs do you mean mostly board level type stuff? How do you handle all of the encryption and road blocks OEMs like to put on the software? Doesn't that make it challenging to get a board diagnosed or operating properly again?

<comment><USER43> Mostly board repairs, but also wiring on the cars itself.

Like I said, I mostly work on older cars, since those are the ones where it makes economic sense to do this kind of repairs. Those cars are usually from the era where ECU's had little to no encryption, or even no software at all (pure electronic based ECU's).

Stuff like early Bosh and Lucas, Porsche CDi.

* Write articles for other people - usually on topics I really don't have a lot of knowledge or feeling about to start.

* Mow lawns - I'm allergic to grass. Builds character.

* Labor - the harder the better. Beats the gym and there is no better way to turn a Budweiser into a $100 beer than sweating your tail off digging a ditch.

* Help startups bootstrap or otherwise avoid "the man" while they find their dream.

* Sell chicken eggs when the hens push more than I can French toast.

* Make films, music, stories, pamphlets...often these cost more than they make, but I refuse to call them losses. Slightly passive income stream.

* Consult - since I was 11 in '81 I've been paid for helping people with their broken technology. I'm not exactly on the edge of all tech like I was, but I still serve a purpose.

* This is an odd one, but I have found it at least as profitable as a few side projects over the years. Be lucky. Actually look for money on the ground ($143 last year), win prizes, expect financial benefits from transactions, assume your (educated) choices will make money.

* Sell plant starts - a little late for this year, but it's one of those things you can save seeds from your regular groceries / food prep at home and early Spring...ba-da-bing ba-da-bang...kind of almost free plants!

* Investment clubs - getting a small community of a tech nerd, business geek, social butterfly, and either an accountant type or law dog, plus whatever else you happen to be friendly with, you can end up with a very smart engine for investing. Invest in either public stock, local businesses, people with ideas, or projects of your team's own creation.

Have fun, and profit!

<comment><USER46> > Write articles for other people

That sounds interesting. What kind of people, and how do they find you? Where are the articles published? How much time do you usually have for writing them (days, weeks, months?) Do they get published under your name or the buyer's name?

<comment><USER45> As far as I can tell, there is no gold standard for text brokering, including TextBroker.com, but start with Textbroker Alternatives and you'll see lots, and plenty of reviews to find something you like.

After that, get old school and check out the Writer's Market Guide 2019 (or anything from the last couple of years). Keep in mind, all the magazines and industry publications out there need a ton of content every month. What are YOUR favorite places to read? Heck, it can be poetry, fiction, DIY, anything.

Timeline, word count, style, pay and all the other tidbits are almost always agreed upon prior to your efforts. Unless you want to pitch a story. Which can be super fun! And these can be blogs, industry rags, magazines, newspapers, and so on.

Enjoy!

But when someone gets referred and calls or sends an email asking for help with setting up an LLC, helping wind-down or sell their business, or even something small like reviewing an NDA, I can jump in.

I'm solo, so I don't have any overhead and I can charge far less than anyone else. This is also entirely a side gig, so volume is so low that I can be responsive, helpful and more like a thought partner who is also helping out on legal.

My net profit can be as high as $1200 per week, $800 on the low side, for a few hours of "work". I generally use it as a fall-back income when I'm in-between tech jobs but I do it if I'm employed or not to keep my paying client list fresh for when I need it. I could make a lot more, I have a "cam friend" who makes $5k/week regular but he does it full time and markets himself and such. I put the minimal amount of time & effort into it.

<comment><USER22> Why would you be downvoted? I've always thought of HN posters as being liberal/libertarian leaning.

Personally, I didn't think twice about it either way. It was neither intriguing or off putting.

</comment></comment><comment><USER50> Three things for me:

1) I own a small rental property in Florida that is fairly low maintenance and pays for the mortgage + a small amount each month on average. This is a long- term ROI play since after taxes, maintenance, repairs, and everything else it ends up being close to a wash until the principal to interest ratio on the mortgage payments improves after 5+ years. I only say this because everyone and their brother in my age group seems to want to retire on rental properties, but in reality it's really not that great.

2) Basic ETF investing in a combination of value-oriented and dividend- oriented ETFs. This is, in my opinion, the only way to get truly passive income with literally zero ongoing effort.

3) I design and 3D print props and cosplay pieces on a referral basis for commission. In reality it's a horrible way to make money since quality 3D modelling for 3D printing is time consuming to the point of the hourly effective rate being lower than minimum wage, but I enjoy it, so it's kind of a semi-paid hobby.

I'm father of 2 twins sisters (11) and a boy of 5 years old.

My father have a degenerative disease (fatal but with slow progression), and my mother spends most of her time taking care of him.

I put all my energy with my kids and helping my parents.

As soon as I realized that I can loose my loved ones, I started making selective choices with my time.

In the past, I was course trainer of linux during weekends. It was very rewarding to teach students that "wanted to learn" and the money was good, too. I remember when a student ssh'ed to a station and executed "eject" in the remote machine - he literally jumped in happiness!

I also made some websites in my spare time but it wasn't so rewarding.

<comment><USER59> It is very nice and warm to hear your story.

</comment></comment><comment><USER60> I write nonfiction books.

I used to be a magazine/newspaper editor. About eight years ago, I made a career change and became a full-time programmer. But I wanted to continue to write. So I wrote a book proposal, found an agent who loved it, found some publishers who were interested, and went with a publisher who offered a two- book deal.

My first book, "Experimenting With Babies: 50 Amazing Science Projects You Can Perform on Your Kid" ([http://www.experimentingwithbabies.com](http://www.experimentingwithbabies.com)) ended up selling pretty well.

My second book, "Correlated: Surprising Connections Between Seemingly Unrelated Things," ([http://www.correlated.org](http://www.correlated.org)) did not do nearly as well. In fact, it bombed pretty hard. I assumed my book writing career was over.

But because of the strength of "Experimenting With Babies," I ended up getting two more book deals, each of which follow a similar format.

"Experiments for Newlyweds: 50 Amazing Science Projects You Can Perform With Your Spouse" ([https://newlywed.science](https://newlywed.science)) came out earlier this month. I'm really proud of it. You should give it to any engaged couples you know.

And "Experimenting on Kids: 50 Amazing Science Projects You Can Perform on Children Ages 2-5" will hit bookstores in May 2020.

If you factor in advances, royalties, foreign rights, and other secondary deals, the amount I've made from my books is about what I make in a year as a programmer. So it's a nice chunk of change, but also a decent amount of work.

Advice to anyone else who's considering writing a book:

* You can do well with self-publishing if you're really good at marketing your own stuff, already have a strong platform, and don't need to depend on an advance. If any of those things aren't true, you're probably better trying to get a book deal with a traditional publisher.

* Writing the book is often not the hardest part. Selling the book is often the hardest part. If you just want to write, but you don't want to sell, this might not be the side project for you.

* If you have a literary agent, you typically pay 15 percent commission. And boy is it worth it.

<comment> em-bee you made one years worth of a programmers salary from all your books? how much work was it to get there?

<comment><USER60> I would say that I did not devalue my time by doing it, but there's a good amount of risk involved, compared with a salaried position.

<comment> em-bee obviously, but that's true for starting a new business too, so if you can manage the risk then this is not bad.

</comment></comment></comment></comment><comment><USER61> I woodwork at a local makershop, I started out making random things for my home and when I no longer had ideas for other stuff I wanted I'd make things and give them away for free to friends.

Eventually other people wanted to know if I can make them custom pieces so I began doing it for money, mostly to cover cost of materials and a bit of time for labor.

Not making big money from it but it's fulfilling work and good to know I could still have a place in a world with no technology. Surprisingly, woodworking shares some things in common with building software.

<comment><USER62> What would you say the commonality is?

<comment><USER61> Aside from the things mentioned: Like software, wood is something that is around us everyday, but very few people really stop to think about how it's assembled. Wood and technology are things we can never seem to escape in human civilization.

People see computers like a black box that does magical stuff, in the same way they will look at a curved wooden chair and simply sit in it, without thinking how it got to be in that shape and how the carpenter knew it would be a safe design for holding a person's weight. People also don't think much about the types of woods used and their special properties, similar to how people don't think much about technology stacks and why certain applications work better than others.

In wood working it's also common to make other tools and jigs out of wood for you to use, to make other kinds of cuts easier. This is the same as writing smaller programs that do one task to help accomplish other tasks. A woodworker may use a series of tools and jigs to produce some end result the same way a programmer may pipe different programs together to make some end result. Each tool is a lot like a discrete program with input parameters that applies some effect to a piece of wood, and their combination allows for the production of a multitude of wood works.

Also, when you get good enough at building furniture, you will begin to wonder why people would pay so much money for something you could easily build yourself, similar to how people wonder why pay for Dropbox when you could just mount an FTP server on a filesystem and use some version control. $400 for a coffee table is ridiculous, I could build the same thing for maybe $100 in wood, and probably better, because I can be sure it wasn't mass assembled by a crackhead following basic instructions in a sweatshop.

<comment><USER66> If you're going long term, the platform doesn't matter at all. With short-term trading quants have a huge advantage (I went through an interview at a hedge fund, I know how smart they are, but their downside is that they have to have high sharp ratio to attract investment).

<comment><USER86> What is special about a tabletop for festool products?

<comment><USER85> Take a look at Festool's MFT 3 table system. It is a grid of 20mm holes, spaced at 96mm on center. There are many time saving and convenient tools made to take advantage of them, and many more custom stuff that craftsmen build to make things easier.

Without a CNC it is frustrating to drill those holes reliably square enough to use them in downstream operations like squaring cuts or aligning/spacing.

It is generating some money, but I am in the process of professionalising whole business and that costs HUGE amount of money so I basically invest all of my earnings and will continue to do so for next decade(s).

Being born into winemaking familly was big gift and a curse. Without having some basic infrastructure there is no way I would be able to afford starting. On the other hand it brings complex familly issues when you try to do something different: I am farming organically, I refuse to use any "modern" additives and even stylistically I prefer doing very dry old-school type of wine instead of what they thought is modern off-dry and semi-sweet wine.

It is not hands off (fair amount of customer support & design work) but the net profit makes it worth it.

</comment><comment><USER114> I organize a conference for developers (see: [https://2018.cascadiajs.com](https://2018.cascadiajs.com)).

Organizing events is obviously very different than programming and shipping software, but it's nice to create something that programmers enjoy and it's been awesome to meet so many industry folks whose work I really admire.

</comment><comment><USER115> This is unlikely to be reproducible, but I bought a foreclosed condo in Seattle in 2013, did a few weeks' worth of work (spread out over a year or so) redoing the kitchen and bathroom, and sold it not quite three years later for $120k more than I paid for it.

I also have a couple of super simple apps in the iTunes Store that earn about an iPad a year worth of money.

<comment><USER34> This seems very reproducible, or at least many people focus on doing this. Donald Trump is probably the most popular example of someone who got rich buying things at low value and fixing it up for a large profit.

<comment><USER116> It's not easily reproducible in Seattle any more. The housing market has flattened over the past year or so. Back before 2018, properties would easily go up 20% a year.

<comment><USER117> Other Washington markets are ripe for this activity though. Lot of money is exiting the Seattle area and buying homes in the rest of the state.

<comment> em-bee i really like this idea, but i am not a fan of the elaborate battle rules in d&d. in fact, i'd like to do roleplay without any fighting at all. just treasure hunting, puzzle solving, etc...

i did some research for what else is out there and found [http://www.susanjmorris.com/dd-for-kids/](http://www.susanjmorris.com/dd-for- kids/) and also [https://www.wired.com/2010/09/rpgkids-a-critical-hit-with- li...](https://www.wired.com/2010/09/rpgkids-a-critical-hit-with-little- gamers/)

but most helpful was this review which i found inspiring to come up with my own ideas [https://boardgamegeek.com/thread/137660/great- introductory-d...](https://boardgamegeek.com/thread/137660/great-introductory- dungeon-crawl-game-kids)

basic setup: there are no monsters, just NPCs that block your path. role the dice to decide who needs to give way. if the player "wins" they get to keep the NPC as a score. if the NPC wins they need to move back as many steps as the NPC roll, and try again when they get there later, or go another way. there can also he other surprises such as treasures or cards that add to your rolls (+1, +2 etc)

the rest can be like any d&d game, but this avoids the whole battle scenarios which is not something i want my kids to grow up with when i don't even like it myself. (when i play online RPGs, i find fighting just a nuisance that prevents me from enjoying the rest of the game)

</comment><comment><USER130> I'd like to do something constructive, maybe tutoring the local college and high school students, but since people are mentioning index funds: I bought a couple Vanguard funds about 8 years ago and have been maintaining an average return of 10-12% which is almost enough to pay rent. I used some of the returns to help pay the down payment for my condo. Now, my rent won't go up anymore. My mortgage isn't much more than my old rent and less actually then one of my previous places. It's also about double the size and arguably in a better location. If I ever get another job some where else and because of it's location I can rent it out extremely easy.

</comment><comment><USER131> When I was in Texas, I used to buy Disk drives in bulk through auction from PC manufacturers Compaq and Dell that didn't meet their QC, test these drives and sell the good ones to retail shops, PC repair shops and individuals. I stopped once competition became tougher, bad to good ratio of disk drives increased, and disk drives became cheaper.

In Japan, several people asked me to teach them English. So I teach them English, some pay me in food and drinks. I also figured out that I was good in helping others prepare for standardized exams TOEFL/TOEIC/GMAT/GRE/USMLE so that became my primary side gig.

</comment><comment><USER132> I never charged money for it, but since I live in Japan and used to teach English for a living, I used to teach English to retired people in the area. I stopped because I don't actually have enough time any more, but it was very rewarding. I'm thinking of starting up again, holding sessions in the pub and charging beer as payment.

Now that I think about it, it's how I got together with my wife. I met her running in a marathon of all things and she wanted to learn English. I said I'd be happy to teach her and after 2 lessons I asked her out on a date :-) I never did teach her English beyond that!

I've been doing it since I was a teen, before I started programming, and the first significant amount of money I made was after I invested all my savings in a small festival I organized with my friends.

As for recording, it's been a fun ride because equipment go so much better and accessible since I started 15 years ago. For recording, having portable stuff is nice, but affording to pick studios because of the room instead of the equipment was a real game changer.

</comment><comment><USER137> I perform data cleansing of excel spreadsheets and sometimes convince them to develop basic CRUD apps to take the place of excel. Depending on the project and the feeling I get about the depth of their budget I charge: per row based on the transformations they need, flat fee if they actually have well defined requirements, per hour for development time if they are convinced of the value in standing up a new web app to handle the process.

<comment><USER37> How do you get clients for this kind of work and about how much do you charge? This sounds pretty laid back and potentially lucrative

<comment><USER137> That my friend is the secret sauce. My first job out of school was for a staffing company that pimped me out to perform similar projects. Word of mouth mostly, it's very lucrative if you have domain knowledge and can sit for long periods of time. It's not Mechanical Turk style cleansing and I have to take personal responsibility for every row as they mostly just suck up my cleansed data and roll with it, which you can't do with ML cleansed data or off-shored cleansed data. I've been thinking of launching a SaaS product but the transition from trusted consultant to enterprise SaaS is not easy. What do you do?

<comment><USER37> I do big data stuff mostly. A lot of that involves cleansing. So working with large excel/csv/other tabular data formats is second nature to me. Familiar with many technical tools that I could maybe use as force-multiplier (e.g. serverless SQL processing, OLAP, RDBMS, python pandas, spark), hence my interest since if we relax the condition that every single row is accounted for, my productivity would likely be pretty high

<comment><USER137> The customers always find the rows that are not accounted for, it's bad form to drop data. We sell high quality data, which you can't claim if you can't account for every single row. You should be careful about delivering an incomplete data-set.

I was a full time college student and was working at a pharmaceutical company full time. I would custom order bracelets at Alibaba with my logo on it. Would pay wholesale price of $0.75 per bracelet and would sell it for $10-$30 dollars on Etsy and my website. It was fun while it lasted. I was making $3-4K a month until dropshipers ruined the market.

<comment><USER139> Would you mind sharing how dropshipers ruined it?

I'm not a dropshipper myself, but I know a couple of people who have gotten into it.

<comment><USER140> Not OP, but I've done some work in the space. The market is just saturated now. It takes such little effort to start a dropshipping "business" that unless you have a really unique angle or spend absurd amounts on marketing, you'll probably make somewhere in the range of peanuts to beer money.

Even if you do find a successful niche market, it won't take long for a low budget clone to jump in, which invalidates a lot of the up front work in marketing and product validation.

<comment><USER142> I had a coworker who literally did a rant, slammed the door of the conference room and quit. He was earning some side money playing online poker then made a go of it full time. His conclusion: This is a lot less fun when it's your sole source of income.

<comment><USER141> Yeah, even if you are good enough to make a decent wage, it can be boom or bust. On a long enough timeline, there will be times you say, make a bet with 4 aces but get beat by a straight flush[1]

Also, most poker players are American - so they're going to need to cover health insurance.

Maybe when I retire I'll give it a go, but I don't think it's practical to envision retiring early to play poker unless you amassed enough savings you could live without the poker income.

First, I play in an Irish wedding band (it's insane how much people pay for wedding bands...and since they're Irish weddings we usually all end up being fed shots throughout the night (this was more fun when I was in my twenties, now I stick with a beer or two so that I'm still standing (well, sitting, I'm a drummer) at the end of the night). Secondly I do quite a bit of teaching / mentoring. It's easier in nyc than in other places because of how many boot camps there are here but companies pay quite a bit for a 6-10 pm twice a week gig. Plus at my job I'm primarily working with php and vanilla js so this helps me keep my react / insert framework or library here skills sharp. I argue that this is still outside the field because teaching beginning web dev is to actually working as a programmer as apples are to oranges. That last sentence was super bungled but I think the point comes across.

<comment><USER150> How do you bottle your products? I see the cans with your logo, seems like a bigger operation than you describe. :)

<comment><USER149> There was a lot of research that was done, but we were able to get into cans with a few key components.

We use a piece of home brewing equipment right now to fill our cans and bottles, the beer gun [1]. The beer gun allows us to purge our cans/bottles with CO2 (oxygen is bad for alcohol), and then fill them from the bottom to reduce foam.

I was able to find a local supplier, that wraps cans in plastic. So rather than printing them, they shrink wrap our label on to them. They're a bit more expensive than printed cans (if I recall 34¢ sleeved vs 19¢ printed). This allows us to order a single pallet at a time, decreasing our storage needs

The last key was the can seamer[2]. I found this early on, and it's been a great little work horse for us. We've put over 6,000 cans through it, and it's been one of the best purchases we've made.

Bottles are the easy one, we just use the beer gun [1] and then a manual capper to seal them.

Happy to answer any other questions! It's been a fun ride trying to figure out how to "mass produce" something on a smaller scale :)

Easy to work on: upgrade RAM, swap HDD for cheap SSD, replace broken keyboards, etc.) We could sell them for a nice profit with very little work. I wouldn't want to do this work on many "modern" laptops since many parts are not (easily) user replaceable these days.

Most passive income just comes from Index Funds/miscellaneous investments. But I don't really see it as income since it all stays invested/just grows until I retire some day. Still trying to find the right app/site/tool to build to bring in real passive income from something I have built.

My winrate online is only a couple dollars an hour. I don't play live very often so I don't have the sample size to say what my winrate would be, but I'd guess $10-20/hr. So, ultimately, not too much money. But if I keep improving, my winrate should keep going up.

</comment></comment></comment></comment><comment><USER195> I build furniture. I don't make much - honestly, I just do maybe 1 paid project per year. I only use handtools (mostly due to shop constraints) Maybe someday I'll be able to do more with it.

</comment><comment><USER196> This isn't exactly passive but...

I used to buy old furniture, refurbish it and resell it on craigslist. I made generally about $20 - $30 an hour. I also kept things for myself sometimes and slowly replaced different furniture items with nicer and nicer items. One year, I had 4 different coffee tables in succession. I found a cool coffee table and kept it, then I found a cooler one weeks later so I kept that and sold my previous one. Repeat that 3 times.

I'd mostly troll a certain thrift shop for antique-ish and mid-century items. It doesn't take long perusing Pinterest and design blogs to get a bit of an eye for what people want to consider collectible. Plus often if you look at something and squint, you an see if shaping it up will make it into something people want. I occasionally hit some garage sales, estate sales were too high priced and competitive. Sometime going an hour before they closed, they would drop the prices super low. %75 off would be better for them for them than not selling AND having to move it to get rid of it. Not always though.

I mostly just used Old English oil or Minwax furniture wax on items. It wasn't unusual for me to buy a $20 dresser, spend an hour giving it a cleaning (with Windex or other dollar store cleaners) and an oiling and sell it for $80 - $125.

I would do some small carpentry repairs on items, usually broken drawers, loose legs and occasionally a crack in the piece that was on a non-essential or non-structural area. You learn to avoid the repairs that are time consuming, difficult to get right or especially those--this is hard to describe--that will either be super easy or will fail no matter what you try with no in between. I avoided painting things, too time consuming plus I hate covering good wood. If anything is missing a knob or matching decorative hardware--it was an instant "no". You'll never find one that matches just right without spending a ton of time--if at all--and if you replace them all, it's expensive. Plus new knobs usually look weird on an antique and ruin the aesthetic of a mid century item.

I have had dozens of people tell me that I am a magician because I could take an old dried out looking item and bring the finish back. Honestly, it was the oils and the wood itself. I's take a piece like a dresser, table or chair, and after cleaning it for 5 - 15 minutes, just spend another 20 wiping the oil on. You just go over every bit over and over to rub the oil in well and also that takes the excess off. Give it a 2 minute wipe down an hour later if you can, using the same rag but without adding oil. (sometimes the wood soaks the oil into itself, but then it's wet and starts to expend. Then the oil gets pushed back out and sits on the surface. This step gets rid of that.) Give it a super light coat of oil the next day, looking for areas you missed or that soaked up more or less oil than others. This takes maybe 5 minutes.

Dressers were my staple. Everyone has at least one dresser, people use them in other rooms for storage or decor. Chairs were okay deeding and also would sell in even number better. Coffee tables, especially mid century items went easily also. Headboards and foot-boards I would buy if they were exceptional in appearance or super, super cheap. With those, any physical repair needed would also deem them a "no".

All my supplies fit in a dollar store plastic basket that was about 14"x14"x12". A few bottles of surface cleaner, oil in dark medium and light and a can of wax. Then a bunch of rags, use the same rag for the oils, one for each color. and one for wax only. Some steel wool for scuffs or hard stains, a small hammer, a few screw drivers and a ton of different sized screws and nails, almost all in the smaller than average to tiny varieties. I very occasionally used a drill and do have a couple long bar clamps for gluing.

The skill needed to bring a finish back is minimal. I'd say if you can clean a bathroom well or polish a chrome bumper, you can make a $10 thrift store item look like a $150 one. Just rub the stuff on and it does the work. People will call you an artist and not realize they could do the same.

I sold on craigslist and usually the people came by in the evenings when I was just making dinner or getting stuff ready for the next day anyway. I have a covered porch so they'd never come into my house, I have a large dog with a scary bark, plus I had a few hidden aces up my sleeve in case anyone got cagey. No one ever did. Craigslist can be a gutter of society but the people wanted what I sold were about 20 somethings, soccer moms, "artsy neighborhood dwellers" of varying demographics or empty nesters. I had a 4 text limit and if someone texted me more times than that, I'd do my best not to arrange to meet with them. That sounds like a dick move, they just want to know about the item, right? But like clockwork, those were the people who would no-show, super low-ball me once they got here or reschedule 20 minutes before they were due. People got one strike and they were out.

The thrift store I went to to was near where I would run errands and so I would stop in there for 5 minutes every time I went to get groceries or whatever. I made one special trip a week on Saturday mornings, right when they opened. I was there 1 - 4 times a week, usually about 3. So it did not take much time out of my day or routine to get stuff. It came to a close because the one thrift store I used to get stuff from really fell off in their selection. In the Pinterest craze, more people started keeping things and "Up- cycling" them themselves. My store also lost a deal with some organization and suffered a drop in items. They also used to make regular pick-ups in areas and I think they just saturated it an sort of squeezed the sponge dry.

</comment><comment><USER206> TL;DR: not making money yet, but enjoying stop motion animation of marble track construction.

Back in the day, my brother and I would use Legos to build tracks for marbles, using roof pieces as ramps. Eventually I started making marble tracks out of popsicle sticks. Over a period of some years, I built a track 2+ feet (70cm) tall with lots of tracks intertwining each other all the way down.

After moving and leaving that old track behind, I made Marble Track 2 over an eight-month period in my free time at work.

I posted the finished track on YouTube[1] and comments fell into 2 categories.

Trolls: U suck, it's garbage, get a gf, etc.

Fans: U rule, it's amazing, make a tutorial, etc.

Me: "Make a tutorial? about how to make a marble track?? hmmmm that gives me an idea!"

So far, I have about 11 minutes[2] worth of (silent) video of little pipe cleaner characters placing wooden pieces onto a stage. They are answering the question "how do you make a marble track?"

The project has its own website[3], which reinforces the story that the characters are building the track.

(fake spoiler) However, it's actually me behind the scenes moving the characters to make the movie in which they build the track!

300+ hours of livestream[4] answer the question "how do you make a stop motion movie which answers the question of how to make a marble track?"

The livestreams are long, dull, often quiet, interspersed with a few ramblings that go through my head.

So, back on track (ahem) for this thread, I believe there are people who'd be interested in this project, and eventually we will figure out how it can be monetized. I am just enjoying the creation process and open to possibilities.

Do you often have issues at work when you feel you're "just asking questions"?

I haven't seen a single person mention their gender yet. For all we know _everyone_ who has replied is female.

Maybe don't assume someone's gender based on data like hobbies?

<comment><USER239> > I haven't seen a single person mention their gender yet.

That's why, in order to establish the answer to OC's question, it is necessary to ask.

> Maybe don't assume someone's gender based on data like hobbies?

Directly asking is the opposite of assuming.

Your attitude is why OC made a throw away.</comment></comment></comment>
