I got myself a Petzl NAO RL for (ultra-)trailrunning, wich is equipped with a USB C connetor for the battery. My first thougt: Nice, I could run it on a bigger powerbank in my backpack. This kind of works, when using a extention cord with 5 kOhm...
Native C compiler (smaller C) with Color text TV system. Under a tiny memory, libraries are hard to link, so library such print, filesystem is on the flash and call from function-table. PS/2 keyboard(US, Japanese) can be used. Library for Color Video...
How It Works Brief Summary I started with a well-known disassembly of Combat (by Harry Dodgson, later improved by Nick Bensema and Roger Williams). To this, I added a K-nearest neighbor algorithm that uses examples from a training dataset to make a...

In another page, I described my adventures converting an Ubuntu DEB package to an RPM package. This provided me with a native toolchain for my Linux workstation. I wished though that there was a solution that would allow far more Linux users, no matter...
This idea was born when i saw this project years ago: https://hackaday.io/project/170961-resistor-color-code-clock-v10 NOTE: There is a bug showing resistor values under 100 since gold nor silver can be displayed. AND the multiplier seems to be...
The 16C2552 doesn't need a lot of glue on the RC2014 side. A single 74HCT138 is used to decode the I/O space and allow the card to be placed at 80/90/A0/B0/etc with the second port 8 bytes above. The standard configuration used on non Z80 ports is to...
