Thanks!
The etch started to undercut the mask, so the smaller font is a bit fuzzy. I have IN and OUT on the sides, and the latter isn't really all that legible because it went too far. I'm still learning about how the electro etching works, it seems to work faster on small areas so the big Pi doesn't erode as fast as small text. It's also important for the etched surface to be on top, and of course that's not possible when you're doing stuff on three sides of a box. I'll try some different techniques next time.
The end result is kind of appropriate, really
It's got a rough industrial vibe that suits the pedal. That may have been accidental but I'll take it
I'd be happy to do a tutorial on it for this forum if desired. I used
this tutorial to get me started. My battery charger is too smart to fall for this sort of thing, so I just hooked it right up to a car battery. Worked a treat.
