Re: microcontroller picking up noise?

I just tried a different board (smaller and without a metal back plate) and found that the problem is much worse. I can't even get the thing to turn on unless I start poking at things with my finger. And, yes, I'm sure it's the noise, not a bad connection.

Anyway, I'm two houses down from the transformer (probably ~100'). If I make one more run and eliminate everything inside the house, what should I do? Should I talk to the power company?
