I modeled the mount that would hold everything at the bottom of the cup. The square hole was for the IR sensor, and it had a deep trough to run wires under the LED. The wire clip had a mounting hole and nut socket to keep it all tight.
I built thirteen sensors, which took all afternoon. To run them, I built a small device that could plug into a USB port and provide enough power at 3.3V to run all the sensors.
I built a small target with five cups. I wanted thirteen and assembled all the targets, but there was not enough room on the lid of my laser tag bin. The reflective coating was from a recycled insulating bag, and it was a ton of work to assemble them all. I would do it with aluminum tape if I were to do it again.
I wanted to replace the front grip with a lighter version with batteries. I sketched a design similar to the previous one, but this one would be longer, with battery cavities. Each chamber will have a threaded plug to tighten onto the battery terminal and secure it.
I used yesterday's drawing to make the first model. I started with the old grip code, but I wanted to build it differently and made several changes. The overall model looked promising.
Sarah, Amanda, Fred Schwartz, and I talked about Fred's upcoming installment of the Fisticuffs comic series and Clerks (1994). Fred called this movie a time capsule, which succinctly describes it and what it captured. We picked a few bones about things that did not age well, and had a great time.
The rest of the summary posts have been arranged by date.
