2022-09-26 (M) 24EngBarostat REV1 Complete

The connection between the piezo element and the circuit board wasn't reliable, so I pushed a piece of wire from the circuit board into the aluminum-wrapped sponge, soldered it in place, and the constant pressure seemed to help. The case started to come apart after I reassembled it for the millionth time, so I added some wood glue. My technique was to apply a lot of glue on one side and tilt the box, so it ran over all the seams. I did this for three sides, let them dry, and then repeated it for the fourth wall. I haven't glued the top since I couldn't service the device, but I added labels. I reconnected it to the computer and lowered the light. I had it set to 20 out of 255, but even at the lowest setting, 1, it was bright enough. I also lowered the tolerances on the potentiometer settings because I set them very high for testing, but experimentation suggested I could go lower.
Labeling with REV numbers is vital
