This is a very short demo of a drinks can cooler inspired by the one Ben made way back in Episode 12 of TBHS. The idea is that a pair of TEC modules are strapped to a hunk of alumin(i)um to cool down a soda can. It was the first time I really used an Arduino and it gave me the confidence to take on more complicated projects like this in future. As an actual cooler for drinks, it worked ok but I could improve its cooling performance with some insulation and more powerful peltiers/heatsinks.
