Jeri shares some interesting build details of the C64 Bass Guitar. The brains of the system is a Spartan FPGA, I was surprized to see that the pickups were made using round disk piezo elements that were cut into rectangles. I didn’t think that a piezo element would work properly if it were cut like that. I guess they are much more robust that I had thought! If you
Wow, this Augmented Reality technique looks like it works very well! Via: Procrastineering “Video results for an Augmented Reality tracking system. A computer tracks a camera and works out a map of the environment in realtime, and this can be used to overlay virtual graphics. Presented at the ISMAR 2007 conference.”
Most of our workplaces are built using wood, metal and plastic. Adding some plants can go a long way to make the space a bit more comfortable. Have a look at the Bio Computer over at Total Geekdom. In this design the computer is used to help heat the soil to promote germination. Â “I started wanting to use the heat from a computer as a way to warm the
The Microchip dspic33f is used for this Self Balancing Robot that chayben from Australia put together. Bluetooth modules are used to achieve communication link between the robot and the computer running Matlab. On the computer you are able to see the many tiny changes that are needed to keep the robot upright. The stacked round disk PCB design looks and works great in this design. “Processor: Microchip dspic33f Sensor:
  Blair Kelly has designed a fun looking RC car. It has an Arduino mounted in the car, there are a number of sensors that allow Blair to drive the car around viewing the drive on a computer screen. There is even force feedback so when the car goes over a large bump or bangs into something he can feel it. With a head mounted display this thing would
This Interactive Mirror project by OpenGadgets is based on the IOIO Microcontroller which looks like it is very flexible. A 32X16 pixel matrix display is mounted behind a 2 way mirror, this display is connected to the IOIO microcontroller and talks to the Android phone using bluetooth. With the current implementation you are able to send things such as low resolution pictures and video to the display. There is
 If you are working on a vision system project that needs to track something your life just became a bit easier. Willem Schwalb just sent in a link to his open source software tracking system, Open Vision Control that can be used to control things such as automated turrets. You can also see lots more videos of the system in operation here. “Open Vision Control was initially created
