I'd like to see a dev board (Arduino, RPi, micro:bit) with V+ lines all silkscreened in red, ground in black, and serial in blue & green. It would make teaching much easier.
It wouldn't even be too hard to design, I just never saw it before.
It's not exactly the same thing, but there's an app that does AR overlays of PCBAs [1] to help with debug. I haven't used it, but it's a pretty neat idea.
Thanks! I think next we'll try to naively increase the levels of red before printing, and see if that helps enough. If it doesn't, maybe it's time to look into alternative red inks that don't fade from heat as much.
I don’t want to diminish your drive and accomplishment, but I can’t help but see the connection between this, and the microplastic world we live in. Creating disposable objects, and then covering them in plastic, seems like a net-loss for the planet.
