Graphic equaliser

Our good friends at Adafruit put this project on their Learning System earlier this month. It’s a beaut: you’ll learn something making it, and it looks fantastic when set up. Before we get into the nitty gritty, here’s some video: http://www.youtube.com/watch?v=AMPJH1LOu50 This graphic equaliser (a spectrum analys/zer if you’re from the USA) is made from a RGB led strip, with everything down to the audio processing run on the Pi. Everything you see in the video is happening in real time. The setup runs Python, and is based on LightShowPi (which was originally designed to orchestrate Christmas lights), so you’ll be able add LightShowPi features like SMS control from your phone if you’re an advanced user. Some soldering is required – but soldering is easy, and this is a good project to earn your soldering wings on if you haven’t already. There’s the usual full and helpful tutorial over at Adafruit, along with tips, a parts list, code and all that good stuff. I wish I’d had one of these for my student bedroom. Imagine the parties!
