I didn’t post for a while, and I blame this on the success of the car project.
Since then, I have assembled and tested the binary clock, which works great except for one bum connection in the hours digits: it rolls over at 28:00 instead of 24:00, which anyone familiar with binary will understand. I tried to just mangle the board into a working state, but that doesn’t look like it’s going to work, so I need to order new boards. A simple fix, but it will take weeks to arrive.
In the meantime, I bought a 16×16 Neopixel matrix and have enjoyed working with that. I created an animated display for a big party we had, and now I’m working on an interactive game with a custom-built controller. More on that later.
