A few years ago, I got a wild hair up my hind-side, and bought a Raspberry Pi to mess with. A small, fully functional computer, running a Linux variant, built around an ARM SoC, it was a pretty nifty bit of kit.
I connected it to my monitor, wired up a keyboard and mouse, added a wifi USB dongle, and had some fun. Did a lot of learning to program Python on it.
But then the move happened, it got chucked into a box, and ignored. With the move done, the house bought, and the project bug biting me again, I have resurrected it.
The first challenge was to actually FIND it. Alas, it was hiding in my monster box of cables and other items. Still connected to the powered USB hub that I had for it.
