I was looking through old photos and found this from the end of 2019.
I'd just built my 2nd hand-wired keyboard and had an idea: almost always keys are spaced at multiples of 1/4U, so why not have a long narrow PCB that essentially embodies the row wiring & holds the diodes.
I don't know what exactly the problem with the design was but for some reason it wouldn't work. (maybe just that the diode pads were on the wrong side??) And then for the next years I didn't touch it or think of it until now.
I wonder if I still have the design files.

@3dprinting This morning I soldered the FilaBilly dehumidifier PCB. I need to crimp up some connectors, reprint the orange standoff/surround (it's like 0.3mm too tight), and finish the firmware. Then it'll be system testing time! I already know the ESP32 boots, either from USB or 12V power.
I found out about r/PrintedCircuitBoard yesterday, so I'll ask for a PCB review there, even though the board is assembled.

@recantha using KiCad is an art. It's relatively easy to learn, and getting your first PCB from #oshpark is not too hard (and rewarding). Designing for low-cost prototype services is more difficult. Using the correct design rules, using supplier component databases, balance default components with special components (if available), label them correctly, double- and triple-check orientation of, e.g., diodes...
Having an up-to-date guide certainly saves time (or money).
