All,
Just about finished with my Dual 445 Build. See below...

I'm down to figuring the best way to drive the TEC.
Has anyone used a Flexmod to drive a peltier?
I am using one Flexmod to drive the two diodes in Series and I have a second driver laying around so if it would work for this purpose that will be a good way to put it to use... If so, would one simply modulate the second Flexmod with the same control signal from the DAC? In other words the control signal would be attached in parallel to both Flexmods...
Another option would be to keep the two separate and use a thermocouple attached to the diode housing to provide temperature feedback to an op-amp circuit which tickles the input of the second Flexmod...
Ideas, experience would be greatly appreciated...
Thanks,
Rob
