Flag-waving, without use of arm muscles

Eben met Alex from RasPi.tv earlier this week, and was given this rather fantastic flag-waving kit for our demo table. (If you’ve got something you think we could use in demos at schools, in talks, and when we chat to the press, give me a shout at liz@raspberrypi.org – we’re always looking for new kit to show off.)

This demo is something you can very easily set up yourself at home, if you’re interested in learning how to use servos. Alex’s setup means you won’t require any expansion boards – you’ll be ready to go with just a servo (very cheap from your local electronics shop – Alex’s cost him £3), some wire, some batteries and a few bits of wood.

And a flag.

Instructions are at RasPi.tv – if you make your own, please send us some video!
