SIM Card Reader
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. read more
AVR Oscilloscope is one of great project based on AVR microcontroller created by Vassilis Serasidis. It use ATmega 32 as processor and LCD 128×64 pixels for display. If you need to measure low frequency i thought this project, AVR oscilloscope, will be usefull. Read more
White LED Flashlght
This project uses 2 AA size rechargeable NiMH batteries (1.2V 600mAH) being recharged by the solar panel and also has a conventional battery holder for 2 more AA size cells in parallel with the rechargeable ones. read more
USB AVR Programmer STK500
This USB programmer has, unlike other programmers, no “chicken and egg problem”. That is: you can build it from scratch without the need of another programmer to load the initial firmware.The firmware is open source and programmed in C according to the AVR068 specification from Atmel. read more
