Roger Smith made a great overview of how a Tesla coil is built. Warning, don’t attempt to build one of these as your first electrical project. Roger was also kind enough to give us an interview, here are the interview results. Interview with Roger Smith Hacked Gadgets: How did you get into the electronic/electrical hobby? Roger Smith: I first got interested in Tesla coils when my older brother
Electricity will take the path of least resistance and that path sometimes includes bridging air gaps. These videos show that with enough voltage the gap that can be bridged can be huge.
The first video shows a hand drawn electrical arc. The second shows the final project in operation. Translated. Original. “Picture tubes in televisions and monitors need tensions of several thousand V for the acceleration of the electrons. For the production of this high voltage the Zeilentrafo is responsible. The Zeilentrafo mostly is on the motherboard. CAUTION! The picture tube contains a high vacuum and can with wrong treatment implode!
This Computer Controlled Robot Face needs to be hooked up to an IM client to freak people out “The goal of this project was to create a head that can be used to display information. The face can be a very powerful method of conveying information, and a robotic head can serve as a very useful indicator. This project is meant to provide computer programs the benefit of using
Have you ever been frustrated with technology? This technology should be incorporated into other devices so that you could yell at your devices… Bad Computer… “In this third year project the student built a robotic face (from Lego mindstorm) capable of expressing emotion, and software that allowed the robot to responded to the tone of the user voice. In the future many more devices around the home may have
Have a look at this laser system, this would be perfect for the living room. “This battery-operated laser system can be controlled using any audio device — including your iPod, computer, etc. — †for the ultimate sound to light experience in your own homeâ€.
Now this is a skateboard that I might be able to ride without breaking my neck. It looks like lots of fun to ride. “The steering control of the board is just like on a regular skate. You tilt the deck side to side. Since the deck is mounted by only 2 rubber bushings, it is able to pivot along this axis by a few degrees. An IR sensor
