Don't know if this will help in this environment but...
Try isolating the brain from the relay/mosfet/etc with a quad-bilateral switch (non-inverting)and wire the output with light-duty fusible link or just a regular low amp fuse. That'll give you 4 switch channels each to play with and a little over-current protection. I build digital switch networks for my guitar stuff (foot board). Still trying to learn midi-based automation.
Thanx Tx dude
I´ll have a look at it
:tiphat:
