I have been reading some on wiki but the info isn't really sinking in. Are Peltier's and TEC's the same thing? :undecided:
So elektro freak.... I used an un regulated power source, is that the reason for the ice? And would a ddl circuit work or do tec's need whole amps?
@jaseth..... It might be overkill if it was a tec for a fridge. But I am also saving up for 20k galvos....
@elektro....again.... So a ddl would work. Would I wire everything like this.... All positives (LD pos- tec pos- pwr sup pos, to ld neg, tec neg- pwr neg) or do I need two drivers? One for LD and one for TEC?
