How to Build a Simple Electric Motor
Here is an way of making a simple electrical motor, to see more interesting videos have a look at the collection that David Colarusso has put together.

Arduino Optocoupled PWM Motor Speed Control
uC Hobby has a nice article about a project that uses an Arduino Microcontroller to read in temperature data and control an optically coupled motor using PWM. “Oscar Gonzalez gives us a simple tutorial for speed controlling a PC FAN and reading a LM35 temperature sensor with an Arduino microcontroller. He covers the use of an optocoupler, PWM (Pulse Width Modulation) and reading analog voltages with the Arduino. This devices
Hide a Hard Drive in a UPS
Hack your old UPS and install a covert hard drive by using the existing USB connector for access. No one can tell that there is storage in there. “Your computer downloads in plain sight. Pictures, movies, music, files, whatever! Nobody will even know it’s there. Not your kids, your wife, a burglar – not even the RIAA!” Via: Hack n Mod
Wiimote Lego Tank Surveillance Robot
I can just imagine how much fun Andrew Hundt, Boris Lipchin and Ned Fox from Carnegie Mellon University had creating this Wiimote Lego Tank Surveillance Robot. “This robot is composed of Legos and uses a handyboard as the control hardware. It has 4 wheel drive each controlled by a lego motor, and a pan tilt mount for directing light and the video camera. The Wii Remote talks to a
Cassette Deck Hack
Lush Projects has an cool tape deck hack that allows for some neat sound mods. “First mod was to setup one deck to allow scratching. To do this I originally removed the pinch roller so that the tape could run free. Later on I realised I could modify the pause button to retract the pinch roller without actually pausing the player. The second mod was to make a tape delay
Big Seven Segment Display
Have a look at this huge Seven Segment Display made by Turd, a Hacked Gadgets Forum member. Other than the ones made by the guys as Sparkfun this has got to be the largest one I have seen. Watch a video of it in action. “I made this for a test. It’s made from a picture frame, some foam from a camping mat, blue translucent film and a shopping bag
Robot Arm Clocks
These are probably some of the most expensive clocks around. 🙂 I would love to have a Robot Arm Clock in my living room though. “The robot arm is probably the most mathematically complex robot you could ever build. As such, this tutorial cant tell you everything you need to know. Instead, I will take shortcuts and just talk about the bear minimum you need to know to build
