REcently got my new 3D printer set up, and boy oh boy, is a big bed and auto-leveling nice. I was just able to take my plate design, intended for the laser, and extrude it as a 2.8mm plate with numerous 1.4mm relief cutouts to allow stabs and switches to fit a little better. I still used hot glue on the stab inserts, especially on the two where I didn’t confirm the plate generator put them on the same side that the original plate did. The new drilled and filed holes are… interesting.
Speaking of interesting, don’t let English majors design your PCBs, folks. In addition to the other oopsies I’ve documented, even though Alps with Focus keycaps have been the target, I actually designed the board in KiCAD based on an MX layout that uses basic 1800/96% caps, because it had the most switch footprints on the bottom row. I then manually placed the Tsangan footprints and connected them. I mostly did this okay, but I did the 1u mod on the left side based on the 1.25u LCtrl, not the 1.5u. So that key is officially hand-wired with the jumper wires threaded through the central post cutout for an MX switch, and I need to see if I can tweak it a bit to clear up the tiny amount of north-south offset that resulted (under 1mm, but I see it and it annoys me, which is saying something for this build). I also completely forgot that I mapped Capslock to be my Fn key, and as it is one of the bodged keys, I did a lot of desoldering and resoldering of that key before I decided to check the firmware. On the plus side, got the LEDs right on the first try!
I also noticed one of the stab inserts was broken, but a little super glue and a sliver of plastic snipped off a grocery store loyalty card 99% fixed that up (sensitive fingers can juuust sense the slightly reduced travel when numpad-plus is pressed from the upper half). So, as has been mentioned in the past, literal garbage. The spacebar is just a touch heavy, but perfectly usable. I suspect the tube insert part of the stabilizing system is a hair off, but I am not even sure I’ll mess with it. Some of these parts are 35 years old, and all of them were assembled by an idiot. Sometimes you just chalk things up to “character.”
Software wise, mostly all good. Sometimes the PC recognizes the Pi Pico as a storage drive, but if I plug it back in that seems to fix itself. Might investigate further. Last big step will be the case. I think I have enough walnut to make something decent.
