We use a 3G iPod to do 44kHz recordings for MAKE:Audio when we’re out and about…and if you’re interested, the updated installer is out with the new iPodLinux Kernel and podzilla as of April 4th, 2005. Fixes some playback issues, adds some new games, AAC support and better all around build. Link.
No plans or how-to yet, but check out this homemade 3D printer “I’ve constructed a prototype turntable from Meccano that automatically lowers itself up to 60mm, currently at 0.75mm per revolution though this can be changed. This is intended for use in experiments in continuously extruding recycled HDPE…Recent fabrications include a 18mm high 19mm diameter cylinder with 0.85mm walls, and a 13mm high 43mm diameter cylinder with 1.75mm walls. Each layer is 0.25mm thick. It’s fascinating to watch in the same way as a potter is, at work on their wheel“. [Via Worldchanging] Link.
All lawn mowers have one basic flaw. Get rid of it and it’s much lighter, goes faster, goes under low branches and between bushes, turns on a dime, saves gas, mows in the rain and lets you have fun to as well. That flaw is the rider. So we made radio-control mowers. Here’s a good resource for making your own remote controlled lawnmowers. Link. Thanks Ken!
Here’s a site that shows how Mike made a working jet engine built from junkyard parts. The engine presented here is based on a used automotive turbo charger, lots of off the shelf parts, and only a few custom made components. Anyone with a little knowledge of engines, access to a reasonably well stocked workshop, some free time, and some excess cash should be able to make an engine…Link.
Carlo wrote in and said “Went to a bachelor party at a lake house Friday night. One of the guys brought a margarita that was made out of a gatorade cooler and a garbage disposal”. I’m curious how well this works. Seems like an interesting way to make a lot of margaritas. View image.
Mad Physics Dot Com is a site created by a couple students/researchers to show how things work, some experiments and demonstrations. The experiments include: The Physics of Glowsticks, GIANT Hooke’s Law Demonstration and The Science of Fire Extinguishers. They also have a neat section called “Ask Mad Physics”. [Via MeFi] Link
Taser upgraded via Fark…Lightning On Demand is a volunteer organization of engineers, artists, scientists and machinists. Our key objective is to produce a controllable discharge of lightning at the greatest physical scale imaginable using modern technology. One of the projects is a 110,000 Volt Taser Cannon. The Taser Cannon can direct a 15,000 Ampere plasma channel through the air along a straight trajectory, at grounded targets up to 35 ft downrange. Link.
