The new shiny circuit boards came today :-)))
However, not all needed parts are in my box in sufficient numbers. Not unexpected. But finding the right parts is always a bit annoying for me, so I have to order some stuff. For testing one new function, I have the parts. So maybe on the weekend, with a fresh mind, I'll heat up the solder iron.
I hope you'll keep us up to date on your experiments (and don't accidentally burn yourself in the process)!
