Nokia LCD Library
admin 
History
I found this LCD make for cellular phone Nokia 3310 by browsing the web at www.jelu.se. There is many interesting things about this LCD: low price, easy to interface via SPI port, can support graphic and text and consume low current. The only thing that I did is writing code who gives you friendly functions to support this LCD. The last version of the library only send the bytes who had changed since the last update. It's considerably reduce the refresh time who can be very important in a batteries powered system.

OneWire Library
History
The OneWire protocol which in fact needs two wires (data and ground) is fantastic for many reasons: you can have a very long cable (250 feets), you can have multiples of devices on this cable and with a simple code you can poll those devices to get temperature, voltage, switch position, wind speed, etc.
MP3 Player
History
I decided to do this project for several reasons: first I like music, second I have a huge collection of MP3, and third I wanted to be able to play them anytime in my living room. I began the project with one major restriction, the printed circuit board of MP3 player MUST be single side in order to do it myself. After 2 months of drawing, I realized this project was in fact ‘feasible’! One major characteristic of this player was the bi-directional remote control. I had to give several information, folders and songs on a small graphic LCD.
