I assembled two prototyping boards for the ESP32. I added headers, three resistors, and screw terminals, which were a new addition. Most of the construction will happen when I solder the incoming wires.
I needed to hold the infrared receivers in place, and I wanted the technique to be reversible and repeatable. I designed a structure that would press from the inside to keep the receivers flush with their square holes. I tweaked the dimensions until the third version, which fit securely.
I spent most of the day repairing the screen holder, which I was trying to run wires through, but my drill cracked pieces off twice. I repaired it, but I focused on the chassis pipe components instead. I wired everything inside the pipe to the microcontroller, including the battery and regulator, so I powered up the ESP32.
I soldered the wires running between the screen module and the chassis pipe and powered it on. The screen and LED worked without any trouble, but the auxiliary button would not do anything. I still need to install a trigger switch inside the NERF gun to test the infrared emitter.
I tracked down the infrared reception problem. The key was to use an LED to track down the problem. I tested the receivers, the microcontroller demo board, and the prototyping board. The issue was a solder bridge shorting the receiving pin and transmitting pin. Once I separated them, the system began accurately reporting incoming signals immediately.
We invited Gerald von Stoddard to join us to talk about Sunshine (2007). I suggested the movie when I heard the premise of his upcoming graphic novel, Love & Death on The Dark Side of the Moon, where our sun is dying. Our affection was all over the place, from Gerald, who enjoyed the movie, Sarah, who saw many redeeming features, to Amanda and me, who could not get over the "style of substance" approach when it came to showing the science. We all loved the cast, though.
The rest of the summary posts have been arranged by date.
