I think that's a good idea about the no solder PBWs, I agree that lots of folks just don't want to solder stuff and would like things that just plug in.

Need to do some testing with the new component values and check that out. I guess I'll have to rely on my Hz readings with the DMMs. The flashing LED is not synching extremely well with the second hand on my watch. It syncs for a while then gets out of step for a while. I don't have any PCBs yet so I can't try it on my layout until then.
I think that Hantek scope may be calling me here, that would be a good way to break it in. I have been eyeing it everyday at least once.
