I’ve been working on a rather silly but entertaining project for the past few weeks:

It’s a hat, that’s also a compass. There are LEDs in the brim – whichever is pointed North is the one that’s on. I’m planning on adding a “party mode” which just lights them up in various patterns, but haven’t gotten around to it yet.
Did I mention that they are pink LEDs?

There’s also a secret buzzer underneath the hat so that the wearer can know where North is without asking someone else to tell her which light is on. The various parts:

Edit: I’ve pushed the source code to bitbucket; it’s fairly hacky, but will be evolving over the next while :)
Anyone else working on fun knitted things, wearable computing projects, or knitted electronics?
