    I think it's time we built a general purpose TEC controller like d4drive but with feedback, maybe a simple opamp PID controller?
    I don't know what type of sensor is best but I have a bunch of LM335's and AD590's to experiment on.

    You don't need TECs for cooling a driver circuit. Just use a normal heatsink. I found a perfect heatsink for cooling the die4drive in my salvaged junk. I can even fit two die4drives on opposite sides of the same heatsink and still not have it run very hot.

    Oh sorry, misread " i need to find a driver for my tec, my tiny tiny tec" as "I need a tiny tiny tec for my driver". I just got home from work (11pm) and I'm a bit tired.

    Still, you need to cool the die4drive with that large currents going through it.
