If you want to go under the sea, this Parallax Submersible ROV project by Richard will allow you to go where most electronics don’t want to go. With a goal of looking at the bottom of a lake in Michigan and watching some fish I think this project will do very well. "This ROV is tethered to the surface with a 6 conductor Ethernet cable and nylon support line.

This DIY Subwoofer Project Build shows that it is truly possible to make a sub that looks (and probably performs) better than lots of the stuff you would find in your local electronics shop. The use of leather and high gloss plastic panels really add to the high end finished look of the speaker. "The box itself will be built of MDF board. I chose MDF because I can
Every time I see a microwave beside the curb I think of all the things that could be made with the MOT (microwave oven transformer). Bob Davis just finished some of his 2400 Volt Soda Can Crusher experiments that uses a MOT, some large caps and a handful of other electronics. The crushing results are a bit more dramatic in one of his last can crushing experiment which used
There are radio designs that require no batteries. Rick Crammond has been playing with a radio called the Beta Blocker Spirit Radio. Have a look at his other crazy radio experiments here.
NerdKits demonstrates how make a Microcontroller Real Time Clock using system Crystal Oscillator by using system interrupts. "This project demonstrates a minimal piece of code that shows how to use interrupts, as well as the ATmega168’s onboard Timer/Counter modules, to divide the 14745600 clock cycles per second down to just 100, and to keep time accurately in seconds."
No this isn’t a CD-ROM drive that has been modified to scratch my head but rather a mechanical assembly in a CD-ROM drive that has me scratching my head wondering how it functions. A few weeks ago I ripped apart an old CD-ROM drive to get a DC motor for the VHS Tape Storage Drive, the circuit board was also cut up while testing the CNC machine that was
