Grindfest, a biohacker gathering, includes electric knife fights as a bonding and exciting tradition. I've been rebuilding the knives over the years, and this time, I had to replace one crooked blade and add new layers of aluminum tape to three knives. The red plastic switch adapters were smoothed out with acetone swabbing.
Last year, I supplied three knives for the tournament, but we barely made it to the end with a usable pair. I wanted a fourth knife this year and gathered parts to make it. I made the handle from clear polycarbonate tubing and the electronics from a damaged knife. I modified a training knife with a saw and razor knife. Grindfest2024 is ready with four working knives.
I received the latest parts for the PCB Dice tower, so I assembled it and soldered the electronic components. Some bezels looked great, but the colored ones did not match the aesthetic, and the black ones did not pop. I used paper towels to dampen the light on this version.
The PCB Tower parts arrived with the Grindfest badge parts. I took pictures to make a parts list for anyone assembling a badge. I made pictures of logically grouped parts and one final image with every component.
I took pictures of each step while I assembled a badge. I went out of order, so I must ensure the images go in a logical sequence. The assembled badge worked perfectly.
I gathered my parts and assembly pictures into a manual for collecting and assembling parts. The document was six pages long, and I wrote eleven steps to assemble everything.
The rest of the summary posts have been arranged by date.
