I wrote a new rule draft and sent it to my playtesters. The rules have been gelling in my head for a couple of months, so I think I conveyed them succinctly.
I made a bowtie based on Ms Pac-Man's hair bow. The low-resolution bow should be fun to spin on the badge, wear on the neck, or on the head. I want to make a few changes, like rounding the corners and adding slots for an elastic band.
The REV3 PCB and accessories arrived. Since I forgot to order a motor mount, I had to cut one, but I made a working badge. The accessories looked great, except the 555 timer board, which acted like a one-shot instead of an oscillator.
I redesigned the bow so I could attach a backplate and clamp an elastic band to wear it as a tie or a hair bow comfortably. I wanted a single board with holes, but even a narrow band required large holes.
My 555 accessory did not work, so I tracked the problem down to the circuit, which was designed for 6 to 12 volts. I found a 3V version and built it on a breadboard. The red light stays on most of the time and occasionally flickers the green light, but I can change that with different resistors.
I modified one of the resistors to make it alternate lights more often and evenly instead of 9:1. Once I was happy with the performance, I translated it to the schematic and regenerated the PCB. The board has two lights now, which is exciting.
The rest of the summary posts have been arranged by date.
