[sdiy] Funky Beta

[Kyle Stephens]

Ah... an old nemesis: accidentally reversed pins. I do and don't hope it's that simple. It'd be a problem solved if it was just that, at the expense of me looking somewhat silly ;P

When I check the 3906s again, I'll see if they are just sucky in the first place.


Thanks all for the help!
