This project was conceived from an interest in Radio Astronomy, Particle physics and a discussion at a Dorkbot Meeting about a number of different project ideas I've had. The one idea that seemed to strike the most interest was a Cosmic Ray Detector.
The main aim of these projects is to develop detectors that are easy to build, low cost (relativelly speaking) and has some kind of usable output to graph, visualise or sonify. Note that in many cases here I'll be using components and materials not necessarily the most ideal for the purpose, making use of what is available or what I can scrounge including surplus or hacked equipment.
Please note, this group of projects are not intended to achieve any significant scientific outcome, other than creating interesting displays that clearly demonstrate the harmless natural radiation and interstellar high energy particles that are around us and pass through us everyday.
They have really nice displays at CERN that show cosmic rays zapping across a TV sized screen. I thought it would make a really cool decoration but apparently they are difficult to construct.
