2026-01-24 (Sa) BonfireLaserTag Voltage adjustment and problem listing

The voltage boosters between the battery and prototyping PCBs were not adjusted, and I had to set them before I could connect a microcontroller. I added a battery to each tagger, which were finicky about getting into the battery holders, but a twisting action helped. I made a note to reprint one, but I learned how to make it work. I clamped my voltmeter probes to the module's output pins and adjusted them all to 5V. After they were set, I programmed five microcontrollers and installed them on the PCB. I had to loosen the mounting bolts to get them into place. One of them was an older model, and the hole for the USB port was too small, so I drilled it out with a step bit. All the screens worked immediately, which was a delight, but I discovered that a couple of the AUX button inputs were not working. I did not test the trigger inputs, infrared receivers, or infrared LED.
