I just subscribed to MAKE, a quaterly magazine filled with DO-IT-YOURSELF projects. Take a look at some of the wicked projects from their first volume:

• 12: Gauss Rifle
  A linear accelerator for studying high-energy physics costs around $5 billion. But you can make one for about 30 bucks with four strong magnets, a wooden ruler, some plastic tape, and nine steel balls. by Simon Quellen Field in 123
• 44: The Open Source Car: a Design Brief
  The time is right for a true people’s hybrid vehicle. The web is peppered with how-to sites for converting your old car into an electric vehicle, but why not develop SourceForge-style documentation for an open source hybrid? by Saul Griffith
• 84: $14 Video Camera Stabilizer
  You don’t have $10,000 to spend on a Steadicam? Make this ultra-low-cost video camera stabilizer and see how much better your video shots turn out. by Johnny Lee

Groovy!
