I did a thing. Whilst searching Amazon for the best tech Black Friday deals I ran into something I didn't absolutely need but couldn't ignore: An awesome Raspberry Pi-powered robot tank kit.
Take a look at the Amazon listing and you'll see why. It does all sorts of cool stuff like using ultrasound to avoid strategically placed obstacles, using software to follow a little red ball or a black line on the floor, and it also works as a remote control vehicle with your phone as the controller.
