Got a late start, but I'm catching up. Went green to match the color of some other boards that might be in the final build.

Don't feel bad Bob, I have not started yet either. You will probably finish before I do!

Unless you have an oscilloscope, no.

You can buy one from RS Components.

Roberto et All,

I don't know if it could be your problem, but I hope so - it would be much simpler. I just found a mis-shipment from Mouser. The envelope marked R-21 had a 221K and a 2.4 K. I try to check everything but I noticed the different color codes as soon as I opened it. I believe Dario's pics at the beginning of this thread should be used as a guide.

I could have very easily installed the wrong value. So measure all you can and don't trust the writing on a label.

Thanks Bob, I'll check more accurately all the components.
