This hack seems simple enough: 1. Open hatchback 2. Insert jet engine 3. Profit Actually, the guy who added a jet engine to a VW Beetle has a PhD in Mechanical Engineering from Stanford. He claims this is street legal, and even has a snapshot of the police trying to figure out what to charge [...]
CNC hardware: stream g-code to an Arduino

Posted: July 21st, 2010, 1:00pm MDT by Mike Szczys

[Reza Naima] has been using an Arduino as the center of his CNC setup for quite some time now. It handles three stepper motors, limiting switches, e-stop, and spindle control. The sketch he’s using allows him to stream g-code to the popular prototyping platform, freeing him from needing a dedicated PC. It’s worked so well [...]

Break out the two-ply, Ecobot III poops

Imagine our surprise when this article on Ecobot III and the disgusting video above showed up in our feed. The robot can theoretically be self-sustaining forever, so long as it has a food source. Yes, you read correctly, food. Typical robots relying on grub burn the biomass to produce heat/steam/energy, but Ecobot III actually digests [...]
LED matrix with a gross of pixels

Posted: July 21st, 2010, 10:00am MDT by Mike Szczys

This LED matrix is arranged in a 24×6 pattern for message scrolling. There’s no etched boards here, making us wonder where [Syst3mX] found protoboard this long. He’s using an Arduino to drive the demonstration (clip after the break) but you can use any microcontroller with this setup. That’s because he’s using three shift registers for [...]
