There are a few other projects I did listed here https://nestenius.se/about/ Besides that, my biggest project so far is that I created a developer community around 1996 called Programmers Heaven that became my main living for many years :-)

HN discussionWhat a Wow, this brings back memories from my own Sega Mega Drive hacking days. About 35 years ago I built my own hardware development kit from scratch as a way to learn more about the hardware. I documented the project here if anyone is curious: https://nestenius.se/hardware/how-i-built-my-own-sega-mega-d... It's really fun to see Linux running on the Mega Drive. I never would have expected that back then.
