4 Pelteir Plate Water Bottle wired to Arduino Uno Note - I plan to use the Arduino Starter kit to make this project.
Hey everyone,
I've had an idea for a project recently and I would like to get some insight on its plausibility. Is it possible to heat and cool a bottle of water using 4 pelteir plates? I'd like to heat up or cool a bottle of water using 2 pelteirs for heating and 2 for cooling. Could the amount of power for the peltiers to function be supplied from a laptop, computer, or battery pack? The role of the Arduino is to program in some safety features or some things to help the circuit function better if necessary. For example, a feature I want to add in is if the cold pelteirs are on, the hot peltiers are off if nessecary. I might add an LCD to display which setting is on/off if I can (example: Cold: ON, Hot: OFF)
Thanks guys.
When it comes for amount of power from laptop, then this is not realy reasonable to expect even USB3, maybe some older laptops PCMCIA, or hardware docks. When it comes to Desk, They would have to be adjusted to get the ATX from PSU (it would have to be upgraded for purpose) We are still talking about a small Can or Yacult botle...
Even then insulate, insulate (and same again) 
Then its a question of speed and how hot or cold) Battery pack that charges even when not used, used as buffer might work (for a short time).Controlling it from Arduino is easy part using function that switches one on other off whenever you want and then calling the function itself to make sure both steps happen, rather then manualy editing or using one output for controlling power on/off and another on two way relay switching between sets (relay would increase consumption here).
