Here at ArcAttack everyone is all about doing the impossible in your back yard or garage, and one thing that’s high on my list of projects is a scanning-tunnelling microscope.  This atomic-resolution microscope was invented in the 80’s by IBM researchers and draws its image by shooting electrons into a sample at close range and recording the current.  You can make your atomically sharp scanning tip for it with a pair of wire-cutters!

Beside that, it’s on Geocities, which I’m positive was supposed to be shut down last year, but this project is so awesome that they apparently let it stay!
