This modded old telephone from France integrates a Stompbox distortion microphone into its design for signal processing and some nice knobs at the top to tweak the audio output. Check out the parts list at the link below. SUPER LASER BLASTER CIRCUIT BEND
This project details a traffic light control circuit that features twenty open collector outputs that turn on one at a time in a continuous sequential manner. The circuit makes use of the 74LSxx family of TTL integrated logic devices. The circuits are designed to drive light emitting diodes or low current, low voltage incandescent lights […]
Check out Rob’s ice cream machine… via Tim. These are two photos of an ice cream machine made by a local Mennonite. It uses a small gas engine and pulleys to tun the crank for the ice cream. The engine also helps bring the temperature of the consumer grade anti-freeze to -67 F in the […]
I bring my TV-B-Gone with me whenever I go out to eat, but it’s hard to subtly use it without the waitstaff and other customers giving me funny looks. I wanted to put it in something that would be appropriate for eating out (so no hats, sorry, Mitch) that would allow for stealth TV-B-Goning, so […]
From the MAKE Flickr photo pool Sascha’s rocket trades a bit in the way of aerodynamics for a big gain in the style department – Current scratch-build rocket – BT50 with 18mm motor mount. Waiting for paint. Head comes from a candy packet purchased with a rocket in mind :) I’m guessing it’ll make past […]
Florin sent in this link to an interesting stepper motor controller. It uses a single ATmega8 to control all 3 of the motor controllers. Check out the web site for a video, schematics, and sources files for making your own. [Thanks Florin] Although the motors are controlled by the same microcontroller each one can move […]
This is a really interesting article about removing rust via electrolysis. I know a lot of our readers like to re-use and recycle old parts, and sometimes that involves removing a lot of rust. There are various obvious methods of rust removal, but these methods are unsuitable for very old or valuable artifacts as they […]
