I’m just getting started with electronics, but this is on my list of things to try.
I did find some good reading here: http://www.tellurex.com/technology/ (note the pdf versions on the right as well.)
Highlights for me were:
A heatsink is required on the hot side. And cold side should be connected to something.
You can use PWM (>= 60hz) or voltage to regulate the temperature(s) of the device.
The hot and cold side is arbitrary, if you reverse polarity it switches the hot and cold side. So it can both heat and cool which is good if your ambient fluctuates like the outside world does.
Not sure if the Seebeck or Peltier effects confuse me more than Ohm’s law ;-)
Time to setup my first Sparkfun order…
No public wish lists :(
