Hack your fairy lights to flash every time a specific phrase or hashtag is mentioned on twitter. 2014 CHRISTMAS LECTURES assistant Kate Mulcahy walks you through an easy project using a Raspberry Pi, a Pibrella, some fairy lights, and Tweepy. Grab a tin, etch a design onto some clear perspex, and link up your Raspberry Pi. You can set it up to track any phrase mentioned on twitter, and never miss a beat. Be careful plugging LEDs, motors and other components into your Pi, as if they can fry your Pi if it’s not protected.

This is tinkering for the 21st century, using the full array of cutting edge devices that we can lay our hands on: 3D printers, new materials, online collaboration and controlling devices through coding.
