I had another revision of the schematic. This revision should be close to the final circuit for the prototype models. If we create a PCB for the taggers, it will be vital, but then it will need a revision to show the circuit board. The IO list should help immensely as the lines get close together.
I finished the pipe tagger with a back plate. It had four nuts pressed into the sides to attach it to the pipe's interior. The USB port connected to the ESP32 demo board inside. The tagger needs improvements, but it is fine for the first prototype.
I wanted to test my LED and lens configuration with infrared devices, so I opted to use the Flipper as a test component. The default IR remote app can use the GPIO instead of the built-in emitter. I added a weaver rail mount to the tube and printed a lens holder and LED holder. I mounted everything to a length of aluminum rail and installed an LED in the prints and connected it electrically. The device had a range longer than I could test in my apartment and a beam so tight I could not activate my television without carefully aiming. I am ecstatic about these results.
I made a couple of testing sensors that would use the IR detectors to illuminate an LED or actuate a piezo element. Both worked, but the sound was too faint and the LED was too prone to triggering with any nearby IR source.
I sketched out an idea for a large infrared bullseye. Each light would work independently to give users an idea of how their gun aimed. The lights would sit at the bottoms of cups mounted to a board with the tops facing toward the shooter. The cups should act as blinders.
We discussed the anime Cells at Work, which we mostly enjoyed despite its formulaic story and unresolved relationships. Sarah made an adorable sticker for the show based on the platelets in the show who appeared as young children in oversized t-shirts and caps.
The rest of the summary posts have been arranged by date.
