Do you like the idea of tesla coils and other high-voltage sparking stuff, but don’t have the time, money or patience to build something that elaborate? Here’s a fun little project that can make big, fat, noisy sparks at least 2 inches long, and can be built very quickly and cheaply. The Marx generator consists of an array of resistors, capacitors and spark gaps. Link.
Lots of MP3 players as final projects- schematics and source included. Our goal was to design a scaled down version of an otherwise marketable product with minimal cost. Our intent was to ensure that our end result would be expandable to include all of the functionality of the most popular players on the market. Link.
I think we’ll see something like this for all music players soon- This Widget for Mac OS X grabs the currently playing iTunes song and gives you the lyrics for it. It checks Lyrictracker.com first and if they don’t have the lyrics, iTunesLyrics checks another lyric database. Link.

This guy converted his truck to an electric truck. These pages are the chronicle of my Electric Truck Conversion Project. I got interested in electric cars after talking to my coworker Jim Miller who was on the Solar Electric Racing Team while he was at school at Cal-Poly. Because I’m an electrical engineer I’ve always been interested in new technology so I started doing some research on electrical cars. [via] Link.
An experiment in constructing an autonomous flying robot. It utilizes blimp design principles, combining a helium filled envelope with 3-channel motor control allowing it to navigate in 3 dimensions. Schematics and C Source included. Link.
Here’s a good resource for making an cell phone LCD in to a small display that gets its data from the parallel port. pcd8544-based displays can be found in some monochrome nokia-cellphones. With some technical skills, an independant, small display with background light can be gained out of these phones at hardly any costs. Link.
