Case Light - ATX Power Supply LED Power Indication

Bill from DSE GLOBAL has created a tool called the Case Light that will ensure you don’t forget to remove power from your motherboard before you work in the case. Modern motherboards are still live when your computer is shut down and some don’t have any LED indication of the lurking power… Read More “In the picture you can see a modified ATX extension cord that reroutes two ATX signal

Morse Code Translated to Text and Speech

So you think that text to speech is cool? What about Morse Code to Text to Speech! This is a great example of the ingenuity found in the Cornell University ECE 476 Microcontroller Design Final Projects. “To implement our Morse Code system, we had to use both hardware and software. Since the Morse Code audio was that of a 750 Hz sine wave, we had to build a Schmidt Trigger

PIC16F84A Disco Light

This PIC microcontroller Disco Light looks like it produces the same effect as the professional ones costing big dollars. “This is an early picture of my discolight effect. Because of the AGC circuit theres no need for potentionmeters for sensitivity adjust. I replaced them with trimmers. Now the microphone is on the control electronics because theres no need to place it outside the box and the possible noises from the

Arduino POV

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

DIY Telit GM862-GPS Vehicle Tracker

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

BeeLine GPS

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.
