Evil Mad Scientist has another great tutorial on their website. This time it’s an easy way to control high-power LED’s. They came up with a simple circuit that uses a “blinking” bulb from a string of holiday lights instead of something like a 555 IC or micro-controller.

One of our readers sent in the really interesting data logger. It uses an Arduino to capture the Nunchuck’s accelerometer data and stores it to the eeprom. I used a Microchip 25AA512 eeprom. It holds 64000 bytes. Normally the accelerometer data for each axis is in a range of about 1 to 1000. I scaled […]
This couch was built from hundreds of old mouse pads that were on their way to the garbage bin since newer optical mice don’t need the pads for traction anymore. Rather than toss them, this maker decided to turn them into a spongy sofa that is perfect for the tech obsessed office. Mouse Pad Couch
This AVR based home monitoring system uses an ATmega8515 microcontroller, wired and wireless control and a 1-Wire temperature network that will allow you to monitor your house from any Internet connection. Plus the whole project is downloadable from the link below. AVR-Based House Monitoring System
This homebrew RGB-LED controller connects up to a PC and can be changed by hand or can be set to change with any playing music. Also, like the popular Philips Ambilight, it can be made to change color dynamically to the dominant color on the screen. RGB Ambilight LED Controller
We wrote about Dennis Havlena back in 2005 and I thought it was time for an update. The instruments are still great, but now we have video of a lot of them being played. Check out the collection of homemade instruments by Dennis Havlena
