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.

Recantha’s only gone and made a tricorder.

I’ve been waiting for…ooh, just over a year, for someone to do this. Recantha , an old hand here in the comments and on the forums, has built a tricorder

Meltwater’s RGB LED libraries lesson

Meltwater (of MagPi fame) has been working on some affordable teaching add-ons for the Pi. He’s demonstrating what you can do with one of his little kits with this natty tutorial where you’ll be creating your own Python library, and using it to do some low-level control of the GPIO

Bilingual R2D2

Sadly, I don’t have any more information on this project besides what you can see in the video. Which is a grave shame, ‘cos it’s brilliant. Greensheller, who is somewhere in China, has made his girlfriend an interactive, multilingual, face-recognising R2D2 for her birthday, using a Pi and some other off-the-shelf electronics
