Holography without Lasers: Hand-drawn Holograms (1999)
I've stumbled across a technique for drawing holograms directly upon a plastic plate by hand. It sounds impossible, but I've been sitting on the livingroom sofa making holographic images of floating polyhedra, words, 3D starfields, opaque objects, etc. No laser, no isolation table, no darkroom, no expensive film…

Cheating at chess with a computer for my shoes
I have come up with a new way to win at chess: I have connected up a Raspberry Pi Zero in my pocket to some buttons and vibration motors in my shoes, so that I can surreptitiously communicate with a chess engine running on the Pi. The project is called "Sockfish" because it's a way to operate Stockfish with your socks.
