Here is a cool project that you could build for about $20.00. Check out the full build details. “This project details a small & simple, but very powerful USB charger for your mp3 player, camera, cell phone, and any other gadget you can plug into a USB port to charge! The charger circuitry and 2 AA batteries fit into an Altoids gum tin, and will run your iPod for hours!
This robot looks like an interesting project. If you can wait for a bit they will have some control boards available for sale soon. “Looks as if some enterprising hacker has built himself a robot that runs off a Nintendo DS handheld. The proposed specs are here: # 20 Digital Input/Output for multipurpose use. # Customizable with you own Motors and Sensors # Wireless programming and controling. # You can
Ryan from Googlemarks brought us the NERF Rifle a short time ago. Well he is back at it, this time he has built a microcontroller based capacitive sensor. “Capacitive sensors have historically been regarded with fear and hostility among hobbyists. They’re notoriously flaky, unreliable, and difficult to design. Further, they traditionally fall in the “analog domain” which is something the casual microcontroller hobbyist can sometimes wince at. They usually require
If you are looking to play around with X10 technology, this project may be what you are looking for. “I was looking for a cheap way to interface my PIC microcontroller projects with my X10 home automation system. Plug-in serial X10 interfaces have to be … plugged into the wall, so I thought a good alternative would be to hack a wireless X10 remote. It worked… here are the details.”
You might remember the Hard Drive Laser Oscilloscope from a few weeks ago. I have had many inquiries about how to build one. This page should give you enough details so that you can make your own. Basic Overview A hard drive voice coil circuit is hacked to allow it to be directly connected to a stereo output. This allows audio to move the hard drive read write head. Mirrors
Zack Anderson and Russell Ryan over at MIT are playing hard, not sure where they find time to study. 🙂 Check out the elaborate dorm room automation system they have developed. “What happens at 4:10 am when you have a bunch of MIT students hard at work? Naturally, they throw an instant party with their automated control system. Since moving into my dorm this last fall, my roommate RJ Ryan
Looking for a fun way to destroy all of those old CD-ROM disks that have confidential information on them. Give the Hammerhead a try! “Hammerhead the CD thrower is composed of two main parts, the head that throws disks, and the tail which feeds the head with compact disks. Two big “4×4 off-roader” (8466) wheels, rotating very fast, grip the CD as it is inserted between them by the feeder,
