I opened the taggers and installed a battery so I could adjust the voltage boosters to 5.0VDC. A couple of battery chambers were snug, but I installed the cells by twisting a little as I pushed them in. I programmed five microcontrollers and inserted them onto their mounts, but I did not check all the connections. The screen all worked, which was a huge relief.
I had high hopes about finishing the troubleshooting in a day, but I discovered that two taggers were not receiving infrared, none of them were transmitting, and two needed solder work to repair faulty ground connections for the buttons. I fixed the IO, but the infrared will be trickier.
I modeled a handcuff key to upgrade a whistle design that protesters were using to alert people when ICE was nearby. The prints were too fragile or too bulky to work on my cuffs.
My wife and I bought a dual-extruder printer, but the previous owners told us that it was prone to clogging. They were also using high-temp and abrasive filaments, so it seemed like a good investment. I tried clearing the print heads with tweezers and dental picks, but I had to completely open both units, four print heads total, and dislodge lots of broken filament. I need to replace two nozzles, but I was proud of my refurbished extruders.
I churned out the first batch of whistles on an old Sovol printer. I had to figure out which software to use, decipher the monochrome screen menus, and level the bed. Fortunately, the software was CURA, which I was familiar with. The bed leveling was automatic, and the menus were straightforward, but there was no preview image, so I had to rely on file names.
We watched the biopic Rustin and appreciated it for its acting, casting, immersion, and entertainment value. We did not hesitate to talk about the things we would have done differently, but we did not agree on what that would be.
The rest of the summary posts have been arranged by date.
