Here is some starting help: I did a pwm thermal controller. I used a TEC (thermo electric cooler) that I controlled with PWM thru an IRF530 fet. I also used a Dallas 1 wire temp probe for feedback. I used a PID loop for temp regulation. See: http://tech.groups.yahoo.com/group/Meade_DSI/files/dsi%20cooling/ this should get you started. JoeT
