Hey guys. Ive tried lending some brainpower, now its time for me to ask a question. Have any of you seen a guide or circuit schematics for DIY Pletier controllers? Im looking at a building something with a couple of op-amps and thermistor reference. I got a $5 peltier off Ebay thats rated for 8Amps/15Volts. I could just start wiring things up with op-amps and trial/error my way through, but some reference would be nice. The most I found so far is on-off controllers, and I would much preffer feedback through temperature refference. Im mostly looking for links that anyone has come across, so I can do my own homework. Thanks.
