cool/ sorry for the pun what got me was how quick a tec will cool ,and power output goes up and how quick the power drops when the Tec's turned off, three for a watt of red now we are getting somewhere nice Andy con
one big problem, i had robins driver set to 700ma and it got way to hot. so had to stop the whole test.
i need to find a driver for my tec, my tiny tiny tec

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.
dont worry its in hand
cough cough

ok found a new psu for my tec
6v at 1amp
diode running at 338mw seems to be stitting there for the moment, lets see how long for!

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.
what!!!!
im using the tec to cool the diode, not driver

i think im running somewhere in the region og 550-600ma
treat em mean keep em keen!

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.
