You're welcome. But damn!! I didn't even think of the fuses when you said you were loading binaries into the Atmega. I have been bitten by the fuses myself and I even have a textfile I made that has the correct fuse setting in case I forget. But I have never seen bad fuse settings make the VCC regulator get hot. I still don't understand why that would happen. Crazy HV rail makes perfect sense but I can't figure out how that would affect the VCC rail.

I guess I'm so accustomed to "everybody" posting here using the pre-loaded Atmegas that Ian puts in the kit that I didn't even think about fuses. But actually not everybody uses them. At least that's going to be my excuse! ;)

Anyway, I'm glad it's working now.

Look into it later when the dust is clearing off the crater.
