PIC Microcontroller Touch Keypad

Check out this cool PIC Microcontroller Touch Keypad by Mondo Technology. I love the simplicity of button press detection. There are lots of industrial buttons that do this exact thing but they are very costly. “This board layout was created using the SOIC version of a PIC16F627A without drawing the usual schematic first. Most of the part values are etched on the Layout. The SIP resistor packs I used are

Wicked Lasers Photonic Disruptor

This Wicked Lasers Photonic Disruptor is some piece of equipment! If you are needing a laser to do power point presentations have a look at some of the other laser pointers that Wicked Laser offers, if you are looking for a non-lethal weapon then this may be for you! Watch the Future Weapons video of the Photonic Disruptor in action to get a sense of how it operates. “The Photonic

LED Coffee Table

Using a bunch of microcontroller controlled white LEDs is one way to jazz up a coffee table! Check out the LED Coffee Table that Evil Mad Scientists has developed. If you think this technology would look nice in your table you are in luck since you can purchase a kit to build your very own. Video after the jump. “Our kits include the giant printed circuit boards, components, instructions, regulated

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
