I recently picked up a couple of these kits http://store.qkits.com/moreinfo.cfm/FK934 to try and control a few TEC's. One kit will be used to control a TEC that will be cooling two blu-ray diodes combined with PBS for a scanner. The other kit will be used to control the TEC in a TO-3 635nm diode.
One problem I found is the output is AC and I want to control a DC output. Here is where I found the suggestion to get this kit http://www.photonlexicon.com/forums/...troller&page=2 post #30.
Another problem I found is this kit uses an IC to detect temperature and I want to use a themsistor inside of a TO-3 diode to control the TEC. I might be able to replace one of the 10k pot's that is used to set the on/off TEMP with the 10K thermsistor inside the TO-3. If anyone has any suggestions to help use this kit for my application that would be great.
