I was at risk of running out of steam again, so I let myself tackle small jobs. I wired the LED side wires for octave 2. First, I had to drill a hole in the wooden platform at the top of each base, then I added a wire to each LED. The wires were long enough to reach the prototyping PCB at the center.
I finished wiring on the second octave. I landed the wires from the LEDs and made solder bridges between them and the resistors on the prototyping PCBs. I was ready to start on the last octave.
The last octave's PCB was the fastest since I did it a couple of times already. The new lesson was that, when I had to bend some pins to place them into an offset socket, I should insert long wires into the socket and lower the PCB onto them, bending the pins in the process. The final octave's PCB was finished and ready for the IO wiring.
All the previous keys were binding, so I ran a test: I put a keycap in place and measured the friction, then retested with the wires in place and noticed a significant difference. I will have to redesign and reprint the keycaps. I soldered the 0V wires for the third octave's operators so that the signal wires can be soldered next.
My comb binding machine is awesome, but I always had to carry a clipboard or write on a table. I drafted a slate with the binding pattern and cut it from 3mm (1/8") plywood. The resulting notebook was perfectly rigid, the backing was reusable, and there was no metal, so it could not scratch anything.
We watched Keeping the Faith (2000) with Alex Schumacher and Aaron Cohen and peeked at their upcoming comic, Schticks & Stones. Both were unapologetically Jewish and never treated the audience like uninformed children. The movie had some problems, and given that it was from 2000, it was a bit better than most of us feared.
The rest of the summary posts have been arranged by date.
