October 19 - Hardware Design Competition At Diptrace
Articles tagged with: Projects
This project details how to build a Smart/SIM card reader/writer for experimentation and investigation of SIM & Smart cards.Once the reader design is built, the open source software can be used to read from and write to the card. Together they can be used to backup/restore stored SIM card data, recover deleted SMS’s and phone contacts, examine the last phone numbers dialed, etc.
For about $30 in parts for the core amplifier and a weekend of soldering, you can enjoy premium audiophile sound through your MP3 player or iPod.
Take a 3rd grader with an idea, a Nuts & Volts article, and a technodad, and what do you get? Check it out here!
Here’s a thought. How about a contest? Maybe we could cough up a few items from the Nuts & Volts store as prizes for the best projects? If there’s enough interest, we’ll put together some simple guidelines and make it official.
This is a new kit in the Nuts & Volts store from the article in the February issue. Using just a few components, you can easily transform your traditional bulb flashlight into an energy-saving, super bright LED flashlight. Complete kit available now. Digital Flashlight Conversion Kit
