Now, I am working on my ISEF project with pumping Cr doped gain meduims with 430nm light from high power LEDs.
I am in need on a schematic for a TEC temperature controller using a resistive thermocouple. I need the TEC driver to take at least 30W at 12V. I have the TECs already (Marlow rocks!) and I have solder to solder them to the parts. I am good with electronics so making a complex circuit is not a problem, I just can't seem to find any of the information I need.
In addition to the TEC driver, I am also wondering how you typically build a starting delay into a system? As of now, I am planning on incorperating a STAMP microprocessor to control the delay and the currents.
If you are interested in my project, send me a PM and I can further explain it.
