Re: Flyback diode on sanguinololu heated bed control board.

Thanks Traumflug!

I actually added one on the relay coil circuit just for safety. :)

I think I need to spend more time on the WIKI - LOL
The SevenSwitch uses a more pretty design and of course a MOSFET so no click-clack.
I'm going over your build guide now, for education!

Though I do enjoy re-inventing the wheel!

Thanks Again,
