That's better. :smile: It's been a while since I've seen individual logic gates...


These are a few 555/556 timer based circuits I was thinking of:

Correct. It would be more for show than go, I just think TEC's are really cool! You'd only need to run about 50-70W through it to keep it nice and chilly. That kind of power is nothing compared to the power that would go through the ESC at ultra-low temperatures. I only suggested the idea because of the single FET board, which makes it possible.

WE DO NOT recommend attempting to remove the MMM heat sink. It would be difficult to do so without damaging the FETs. (besides, removing the heat sink will void your warranty. )

I see. So it IS thermal epoxy! That would be difficult, and yes it would most likely pull a few FETs off the board! :mdr:

If it's the same stuff you use on the MM, a few minutes in the freezer makes it quite brittle and easily pops off. :smile:

So in other words I'd need to use a different thermal medium with the TEC as well.
