Fluorescent Light Inverter with 12V Supply

The project is considered low-cost since it only uses 20 or 40W fluorescent tubes with 40W being the most efficient.

Digital Clock Featured Spectrum Analyzer

The project is a computer controller spectrum analyzer and clock which was constructed using two light emitting diode on 5x2 matrices.

Multi-Purpose System with Radio, Alarm Clock, and Thermometer

The project illustrates the use of a microcontroller for combined tasks to create a radio-clock-thermometer device.

Single Board with AVR Programmer and Debugger

The project is known as Evertool which is an AVRISP/STK500 and Programmer/JTAG debugger on a single board, which is compatible with AVRStudio with firmware upgrade capability.

ATmega8 Based Lithium Ion Battery Charger

The project illustrates a universal charger for Li-Ion battery using a Smart Battery interface based on Atmel ATmega8 microcontroller with GCC software.

Multi-Chemistry Battery Charger

The project produces a battery charger that may be used to charge NiMH, Li-Ion, NiCad, sealed lead acid, and rechargeable alkaline batteries.

Micro-Amplifier Based on LM4780

The project was based on LM4780 IC which is a 60W stereo power amplifier in order to produce the micro-amplifier.

Current Regulated Luxeon Star LED Driver

Using an LM317T adjustable voltage regulator with a current programming resistor is the basic concept of this project in order to get a constant current source to safely drive the Luxeon Star.
