I struggled to install a potentiometer near the conical lever because the plastic was so thick. I also installed a USB-C port and two MIDI ports near the back, where I can easily plug into them while playing.
I dug through the largest connectors inside the guitar controller and decoded which wires corresponded to which buttons. I figured out the connections on the headphone jack, which were different from the three connections I assumed.
I drafted the schematic for the new guitar. I should have used CAD for the first schematic, so I would only need to redraw a few things, but I slacked early on. The new drawing is nearly complete except for the synthesizer and the second IO expander.
I added the MIDI synthesizer and speakers and completed the second IO expander's connection list. I should have planned the layout better from the start because I created a very wide drawing that would not print well.
My old apartment building had a "Maker Space," an empty room with sturdy tables. I went there to solder, but my new apartment does not have such an amenity. My solution was to bring a wheeled cart with a battery-powered soldering iron into a stairwell and sit on a folding stool. I ordered a 12V fume extractor because I sat under a building-wide smoke detector.
I removed the guitar's motherboard and all the cabling. I carefully removed the wire connectors to preserve as much copper as possible. Lastly, I trimmed and soldered each conductor.
The rest of the summary posts have been arranged by date.
