I still have 2 of them that I still use on occasion.

Api if it has one. Otherwise AutoIt or Autohotkey

A long time ago lived in an apartment and used an openwrt router and some can-tenas to connect to the leasing offices guest wifi. Worked okay for about a year. Made sure to limit my torrents to after business hours. Then i was able to buy my own service so retired the setup.

Freespace 2 comes to mind. The whole game engine was open source not just the game itself. Looks like there is still a community building on it too. https://scp.indiegames.us/

Finished rewiring and replacing the control board on my Robo R1+ (the first 3d printer i ever bought). It started powering off in the middle of print jobs a few years ago. So instead of replacing the stock board i bought an skr pro 1.2 control board.

The parts have been sitting there for a while but finally spent some time on it this week. Flashed the reprap 6.5 firmware and wired up the tft-3.5 v3 control panel. Just need to finish the tuning and configuration, then it should be printing better than new.

I have another fdm printer(creality ender 3 mqx) and a resin printer(elegoo mars 2). So this was just my ‘f around and find out’ project printer.

Hanging out at the house working on some projects. Then I am taking my partner out to dinner and a performance of Mean Girls the musical.
