STEM – DIY Electronic Mini Fridge with Peltier Cell – 12V – Kit

Based on a Peltier module that uses semiconductor materials, the system generates cooling through the thermoelectric effect, with no compressor or refrigerant gases: a compact, quiet and eco-friendly solution, ideal for understanding the principles of thermoelectricity.

The kit has an educational purpose: it lets you directly observe and understand how a Peltier cell works and the mechanisms of heat exchange. It’s designed to introduce students, beginners and enthusiasts to the world of electronics and active cooling systems.

Once assembled, the device is able to cool small containers such as cans or bottles, providing a noticeable and appreciable cooling effect. Performance depends heavily on ambient temperature and the container’s insulation level.

Power consumption is around 60W, while the included 12V 10A power supply ensures an adequate power reserve for stable and safe operation.

The kit is not intended to replace an actual fridge, but is a solid base that can be improved and developed further, for example by designing a larger container with better insulation, to increase overall efficiency.

Assembly is simple, even for those with little experience: a detailed video tutorial is available, guiding you step by step through every stage of assembly, from installing the fans to connecting the Peltier module.

The acrylic housing is protected by a film to be removed before assembly, useful for preventing scratches during transport.

This kit is ideal for students, makers, teachers, teaching labs and electronics enthusiasts, and is perfectly suited for use in STEM contexts or as a base for further project development.
