In February 2020 I promised to do a badge for Hacker Hotel 2021. That one was canceled. Then it was planned for 2022, and canceled again. And this year it finally happened, so I can show the results.
It's running on a RP2040 and is inspired by DEC PDP computers. The software is using micropython and has all kinds of puzzles and challenges (plus I put in a brainfuck interpreter)
Currently we're busy providing tech support and squashing the last bugs. There is much more to be told, but that's for another post.
