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
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
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
Congratulation to winner of the last contest. The prize this week is a compact flashlight, it is sure to come in handy when poking around in the dark areas behind computers and server racks. 🙂 This contest will run for this weekend only (August 18 – 19, 2007) . Ending time is based on central standard time. To enter, identify the item pictured above and give an example of what
I thought I had seen it all, have a look at this automated cat litter box. It actually gets connected to the water supply of your house and dumps the waste into the house sewer system. Video after the jump. "CatGenie, the world’s only automatic cat box that automatically flushes, washes and dries. With CatGenie Self-Flushing Self Washing Cat Box never touch, change, smell or buy cat litter again. Includes
