2022-09-30 (F) Weekly Summary

I wired up one of the lids, but my wire was too stiff, so it broke the piezo element. On top of bad wiring, a potentiometer was faulty or damaged during installation and caused many confusing issues when I tried troubleshooting.
Wired internals

I revised my plan and added a landing point for the wires. On the lid, I placed a prototyping PCB that held a foil-wrapped sponge in contact with the piezo element. Everything else connected through the PCB and kept the wires tidy.

I completed the first usable 24EngBaroStat. I tweaked some program settings, glued the box sides, added labels, and improved the connection between the PCB and piezo element.

I shot some video demonstrating the 24EngBarostat, but the audio wasn't loud enough, so I used a different phone. The results were similar, so the problem could have been with the stairwell. I put the demo video on YouTube.

I wired the second board to its lid, but I used silicone-insulated wires for the first time. They were more flexible, less prone to breaking, and held up wonderfully to tweezers during soldering.
Second unit

I fixed the problems with the peripherals. The barometer wasn't communicating because of bad wiring, so I replaced the wires, and the potentiometers were connected to the wrong terminals, so I moved them. I glued the sides shut after confirming that everything worked.
