Leica M4 & Fomapan 400 (2023)
I went past the old hacker space building a couple of weeks ago to document it before it was torn down completely.
Which is exciting for two reasons. First it means that I plugged in everything correctly, and that I got all the bits of the toolchain installed.
Second, the chip is a CH32V003. This is a Risc-V microcontroller with 16KB of flash and 2KB of ram. It also comes with a bunch of communication protocol peripherals and analog to digital converters. And all of that for 10 cents, or about 10% of the price of a SAMD11 with similar memory specs (though granted, the SAMD11 does USB).
I have no idea yet what to do with them, but because they are so cheap I can put them in places that could use a bit of software. Maybe some model railroading stuff, or weird LED controllers. I might also make a small badge I can give away.
The next step is to play a bit more with the devboards I got. I also want to design my own board that will work with the rest of the stuff I designed.

I screwed up something here, resulting in very faint negatives. They were salvageable, but all the photos from this roll are Extra Crunchy.
