Thanks for the link. Very interesting site. He does seem to have "some skills".
The Arduino post by Wolfgang inspired me to start tinkering with the project i began on an Atmel XMEGA ages ago.
Previously, I had ported the Arduino PID code to the xmega, today I got the NTC front end working. Tomorrow Ill try to get the PWM working... Maybe
I will post my Arduino software soon, I had to rewrite a lot, esp interfacing via USB to tty and LabVIEW. This is now pretty final but almost nothing is done for the LD driver. I am looking into a low noise setup, perhaps involving those ultra-low noise Zeners 2DW232 I had been studying for a while. But low noise and "PWM" (for TEC) are an inherent contradiction, so that remains to be seen..
Nice work Dave1
Oh, I see this thread is back to life ))
I suspect that my driver was born prematurely, it has linear h-bridge TEC section and uart interface, but I deliberately did not use digital temperature sensors there. So it was just an ordinary TEC controller
