My old board did not have a native USB controller, so I ordered an updated one. Meanwhile, I looked into MIDI over Bluetooth and downloaded some helpful libraries, but I did not get around to testing them. I wrapped up by soldering wires between the prototyping board and the addressable LED bar.
I got MIDI working with an example sketch. I tweaked it to output pseudo-random notes instead of just one repeating note. When I connected to my phone, I could see the notes appearing on a piano app.
I got the addressable LEDs working. The first example would sporadically skip over lights while I tried to get them to turn on sequentially, aka the Larson scanner or Cylon example. I could not use a serial port for debugging, so I printed the expected values on the screen, which worked wonderfully. I also printed the prandom note playing through MIDI.
I revised the knob design so I could operate them more easily. The large knobs looked nice, but I could not turn them unless I pinched the top. The new model has a nub on top that I can easily reach, but it may be too fragile.
The first stint of my work trip was ending, so I made changes to the faceplate that I can reprint at home. I changed the clearance around the USB port, including making room for the on-board buttons. All of the visible mounting hardware is now hidden inside and mounted from below by threading into the plastic.
We discussed Soylent Green as it tied into Laurie's comic, Path of the Pale Rider, but it turned into a fun discussion about a film in that era that addressed climate change and some really dark topics. We ended by quizzing Fish Lee about the most exotic things he has eaten.
The rest of the summary posts have been arranged by date.
