The Raspberry Pi Foundation have recently launched the Pioneers:
Get together, get inspired, and get making.
We’re looking for Pioneers (aged between twelve and 15) to use technology to make awesome things. We’d like you to get together in a team, make a thing, and share it online.
The most impressive, interesting, and ingenious makes will win money-can’t-buy prizes and cool swag.
The first challenge is to make them laugh:
We’re setting you a challenge to inspire you to get creative with technology. Your challenge? Make us laugh!
This is not a joke. We’d like you to come up with a hilariously genius gag, prank or caper that involves some kind of technology to make it happen.
Get your make ready by Wednesday 22 March
