My first etch! It’ll be a single transistor overdrive for guitar, maybe.

Now … drilling is next. How exactly I will drill 40 holes in that, we’ll find out later. :)

    That’s not what I expected to happen, lol. Cool stuff, though.

    Did you transfer the pattern of your deign directly onto the plate, or did you guestimate?

      Yeah I just painted it on by hand. It’s very rough but hopefully it’ll work. It’s probably not going to make the best solder joints because there aren’t really “pads” at all–the solder is going to leak down each line a bit when I try to do it. I could probably do it much better with a finer brush, but honestly I might as well do a transfer next time.
