This is my homemade Peltier Thermoelectric mini fridge. A Peltier thermoelectric cooler was used for the cooling, a polystyrene box for insulation, and old PC fans/heatsink for the heat exchangers.
An eBay thermostat was used for setting and controlling the temperature which is very handy, it can easily cool down the inside to 2°C.
