Our contribution represents a broader trend towards building open and do-it-yourself (DIY) laboratory equipment. The list of reported DIY setups is continuously growing, providing enhanced customization at prices that can be around 94% less than their commercial analogues . The range of application is also incredibly diverse, like recycling of thermoplastic materials , re purposing of household appliances for synthesis of 2D materials , or building low-cost characterization devices as an spectophotometer or a thermometer , just to cite a few examples. Furthermore, the DIY devices take an important role in the popularization of SDLs. "Frugal twins" to refer to low-cost versions of autonomous material laboratories, and give a wide range of successful examples where this kind of setups, heavily-reliant on DIY equipment, can perform closed-loop experiments in a smaller scale and provide crucial information for the development of high-cost autonomous laboratories. Some of its advantages include full-control of the device behavior, ease for parallelization and modularity, at the cost of sacrificing some of the research capabilities of a high-cost platform. When exploring intermediate solutions between a fully-equiped high-cost laboratory and it's frugal, low-cost twin, DIY equipment becomes essential for adapting existing devices to the needs of the automated workflow and find a suitable trade-off between cost and capabilities. Virtually all these highlighted DIY projects share their Open-Source nature, their reliance in inexpensive production technologies and are a valuable alternative for laboratories all over the world, as well as for citizen science . The DIY trends is capitalizing on democratization of a number of underlying technologies, mainly (i) 3D printing, which has provided an unmatched flexibility and low cost to prototype complex parts in house. Additionally it also backed by a community of makers that share designs and knowledge, allowing a valuable platform for collaboration ; (ii) microcontrollers and single-board computers such as Arduino, Raspberry Pi and others, which again are backed by a strong opensource community that have facilitated the access of non-experts to electronics. They are used at very different complexity levels, from educational tools to professional equipment. The need for material dispensing is common in laboratory practice. In case of liquid materials, there are many both commercial and DIY solutions. In the latter case, for example, there are recent example of pipettes adapted for a collaborative robot use or liquid handlers for preparing different mixtures of reactives .
