DIY Neurophone lets you Feel Sound

  The Neurophone was invented by Patrick Flanagan and used radio transmitter that injected sound into the human  nervous system.  Antennas coupled a one-watt 40kHz transmitter to the body to inject the signals. Seems that Patrick was quite the brain since he developed and sold a guided missile detector to the U.S. military when he was 11 years old. Andreas Hahn has make a modern version of the Neurophone using

Motor Control using an FPGA

  Chris from Pyroelectro shows us how to interface to an FPGA to allow precise control over a DC motor. “The goal of this project is to build a simple one input, one output system that will control a motor. The control input will come from a trimpot and the FPGA or CPLD’s job will be to use the input to create the proper duty cycle PWM output to the

How Ceramic Brake Discs are made

  Wow, making Ceramic Brake Discs is not an easy process. I didn’t think there would have been so many complicated steps involved in making them. I was just thinking it was a slurry of ceramic material that was cast and machined. “This high performance material, made from a special mixture of powders, resins and fibres in a complex manufacturing process, has been used since the 1970s in braking systems

How a Slurpee Machine Works

  Most people enjoy a nice cool Slurpee every now and again. Even though I live in the Slurpee capitol of the world I had no idea how the machines worked. The video above makes it sound like the process is a bit more complicated than it is. I was thinking there would have been a bit more going on under the hood. I had envisioned some type of automation

Taipan Game running on Arduino

  I played a ton of Apple games in junior high, I think Choplifter was my favorite, looks like Taipan was created around the same time but unfortunately I don’t think my school had it. Simon Jansen sent in this hack where he made a version of the Taipan game that runs on 2 Adruino boards. Two Arduinos (that talk to each other) were used because a single Arduino would

Texas Instruments C2000 LaunchPad released at $17

  You probably remember (and have) the Texas Instrument MSP430 LaunchPad, that is the TI microcontroller development board that was released for $4.30. TI is back at it, they have just released their C2000 LaunchPad which has a 60MHz Piccolo processor on board. This processor is sure to be very popular based on the power and price since it looks like you can get them for 2 or 3 bucks
