Anigmo has revolutionized the concept behind a light switch. This new design does not require physical contact to operate. Hand movements in front of the plate is all that is required. Gone are the days of clap on clap off… Click here to see how to work the lights. Source : I4U
After outgrowing the capability of his Homeseer home automation system this guy decided to build his own. The system consists of a wide variety of hardware, everything from off the shelf X10 to custom build modules. For example to monitor his electricity consumption he is counting the number of times his meter flashes in a minute. What does it monitor? The easier question is what doesn’t it monitor… Currently it
So you say you want to build a server farm? Take a look at this one! Hey whatever works right… Source: Digg
Want to build a stun gun? You would be surprised how simple the electronic circuit is. The basic concept is to take a small voltage source and convert this into a much higher voltage. This is done by pulsing a high gain transformer and storing the high voltage in a capacitor. Click on the schematic below for a detailed look at a nice simple design from Electronics Lab. How Stuff
Jesse Sullivan lost both of his arms in a work related accident. He is now the worlds first real bionic man. How does it work? “NECAL uses nerve-muscle grafts in amputees to gain added control signals for an artificial arm. Doctors take nerves that used to go to the arm and move those nerves onto chest muscles. The nerves grow into the chest muscles, so when the patient thinks “close
Big Clive has taken a dollar store fiber optic display and converted it to run off of LEDs. He has built an interesting circuit that allows the low voltage LEDs to operate from 220VAC (yes Clive is not from North America). He demonstrates his circuit board fabrication process and provides a schematic drawing so you can build your own.
RoboNova-1 could be the next big hackable toy. It comes with 16 Hitec servos, the structural portions are made of steel and the exoskeleton is made of durable plastic. The robot also comes with a simple programming language. “Beginners to robot programming technology will be pleased to use the supplied RoboScript programming software. Without knowing any programming language at all users can create operational subroutines with the click of a
