Piano stairs

At a Princeton hackathon a while back, Bonnie Eisenman did something rather wonderful to a flight of stairs using a Raspberry Pi, some lights, an Arduino and a handful of photoresistors. Bonnie, I can’t believe you only won second prize. This is amazing. A while later, Bonnie made build instructions and code available on Instructables – and since then, some other people have been posting video of their own staircase piano hacks. This one, from Alyssa Zachariah, is from Halloween, when she made the stairs up to her front door into a piano for trick-and-treating kids. And there are home applications too: here’s William Kreutinger’s family staircase, piano-fied. There’s a little soldering involved, but soldering is easy, and this is not a hard build – in fact, it’d make a really good first project if you’re new to hardware hacking. Fancy making one yourself? Head over to Instructables for a how-to, and let us know how you get on!
