Yes, I’ve been caught by the Raspberry Pi fever. A bit late, but caught for sure. It all started with a friend of mine handing me a box, saying “Guess you can make use of that way better than I could.” That’s how things started – I’m sitting here, staring at a dark screen, a text console, hacking […]
