Giant ShiftBrite Election Meter
Here is a giant red/blue bar graph to display the electoral vote at Garrett ’s house. It uses 32 ShiftBrite RGB LED modules, two CSG-4M LED numerical displays, a Cubloc CB405 with Quick Start 1000 board, and an ACODE-300B Bluetooth module and run on a small 400MHz Linux server.
LED clock 
The LED clock consists of 60 LEDs which are placed circular around a common analog clock. The LEDs are used to display the seconds. Essential part of this circuit is the LED driver MAX7219 from Maxim. A datasheet is available on Maxim's homepage. The clock is controlled by the microcontroller AT89C2051 from Atmel. This microcontroller is clocked at a frequency of 12 MHz from which results a time base of 1 microsecond. Via software dividers one clock impulse per second is generated which is used for updating the LED display.Two different display modes can be adjusted by a jumper:
1. The LEDs are switched on one by one every second until all LEDs are on after one minute. After that they are switched off one by one every second. This sequence is repeated.
2. The LEDs are switched on one by one every second until all LEDs are on after one minute. After that it starts from the beginning by switching on the first LED.

Digital thermometer
This project is a 3-digit digital thermometer easy to build for beginner or hobbyits.PIC16F628 used to read digital value of temperature from a DS1820 sensor.All 7-segments drived by power logic 8-bit shift register TPIC6B595 with open collector output. For the 7-segment need 12V volt to drive because it have 3 LED per one segment.All segment no need to scan display. Source code programming with CCS C Compiler availible
