Carlo has put his Arduino microcontroller to work as a POV device. Anyone interested in making their own can download the sample code that he is providing. “This is my first attempt to create a persistence of vision (POV) display using the Arduino. The ultimate goal is to mount it on my bike wheel and have it display nice things while I ride. But, for now, it consist of an
Nick from the Digital Dawg Pound just made a cool Telit GM862-GPS Vehicle Tracker using this Spark Fun module. Code is provided on the site if you are feeling energetic. “The GM862-GPS is a hardware module with support for connecting to the GSM (mobile phone) network and receiving GPS position data. It also includes a Python interpreter, this combination makes it the perfect choice for building a tracker. After setting
If you have a RC plane or rocket the BeeLine GPS might add a new dimension to your flights and launches. Have a look at the site for lots more information. “The BeeLine GPS also has on-board non-volatile memory that stores coordinates for download after your flight. 128 k-bits of storage means you get more than 10 minutes of data. View your flight profiles in Google Earth! Here is a
Ben Jackson has built a nice simple PIC microcontroller based project that interfaces to a MA2260 Accelerometer. Ben provides the source code so you can see his interface technique. It is interesting to read that there was a number of errors on the datasheet for the device, in my opinion the errors that he found are totally unacceptable! “This little board demonstrates the capabilities of the MMA2260 +/- 1.5g X-Axis
Build a laser listening device for less than a fast food meal. Video after the jump. “In a microphone, sound waves (differences in the pressure of air) cause a diaphragm to vibrate back and forth, altering its resistance to an electric current. When an electric current passes through said diaphragm, the output forms a complex signal which can then be reinterpeted by speakers or a recording device as sound. The
With a laser pointer, two pager motors, a mirror and a small project box you can build a simple laser projector. The output looks like the patterns that were created by the Spirograph.
This is one electronic gadget that I don’t want anywhere near me! This Electric Chastity Belt is called the Dream Lover 2000. Have a look at some of the construction details and more videos of the creation. Video after the jump. “I have created an add-on to the CB-3000 chastity belt which can deliver an electric shock via a remote control. The philosophy behind it is that proper training can
