Today’s “because we can”: powering antique telegraph equipment with a desk toy stirling engine.

Neat.

Somehow I had never seen this particular Ultimate Computer talk, but it's definitely one of the more interesting ones as I knew so little about it beforehand.

Linux software nerds, I need your help!

I'm looking for an ARM-friendly way to show gamepad inputs overlaid on a fullscreen application

This might be a longshot as I've been searching for options for a while and haven't actually found anything but I'm hoping to avoid writing something myself.
