Here’s a little flashing/debug jig for a circuit board:
I originally made it in acrylic (Flashing jig - #8 by evansd2), then @eflyguy pointed out that acrylic isn’t so friendly to electronics since it can build up static electricity. So I redid it in wood, easy! It was much easier to align the pin holes in acrylic, so it’s good I did that first. I’ll have to remember that next time I’m trying to line things up where I wouldn’t be able to see them otherwise.
