Have you read this thread? At least with the new 9mm 445s you don't need TEC cooling... ~2.5-3W without cooling...just a thought
Sorry if this has been broached berfore... a ton of results show up from searching "Flexmod TEC".
Anyway, my question is, has anyone driven a small TEC (56 junctions) with a flexmod? I want to use this small TEC and the base of my 445nm to cool it. Now, with such a small TEC, I could probably just leave juice running to it all the time but if I am ever in a humid area, I don't want condensation building on the collimator. What I was thinking is; running two flexmods... one to the 445nm and the other to the TEC at the correct current. I would have both tied into the blue modulation so that when the blue is "on" so is the TEC. If the blue is at 25%, so will the TEC be. If the blue is at 100%, so is the TEC. Any thoughts to this? I don't think this TEC is rated for more than two amps so, I am pretty sure the flexmod can drive it. I would go with a Die4, but I have a surplus of flexmods...
I have driven a tec with a flexmod, just connect 5v through your chosen stat, all good.
Squat that bug,
One day I'll finish my build.
"stat" explain.. I want to use a quad driver for the same purpose
you could also drive the modulation input with a voltage divider made out of a 20K thermistor and a trimmer, for temperature setpoint... just draw the voltage curve of your divider around the desired temperature range and voila!
