I want to make a small fridge to carry in my vehicle, and possibly locker at school.

I can get a cooler or styrofoam container, a TEC, a battery, and a fan,, and I should be good to go. A TEC is a thermo-electric cooler that uses the Peltier effect to cool things.

Here are a couple cool vids I found on TECS

I can find them for around $10 on ebay, some even closer to $5. This might be a cheap project. I'll also need a heatsink for at least the warm side and a fan for the warm side.

Recommendations are welcome on TECs and heatsinks. Don't know exactly what I need.

The hard part is next. I want to make a circut the senses the temperature then turns the Cooling unit on to cool down to a certain temperature, then turns off to save battery life. Can anyone tell me how to do that? Maybe a modded thermostat?
