Micro-Step Driver for Bipolar Step Motor

The device is designed to use parallel ports in order to connect a bipolar step motor to a personal computer.

Extender/Repeater Device for IR Remote Control

The goal of the project is to show how an IR remote control extender/repeater was built in order for electronic appliances from a remote location to be controlled.

Unipolar Stepper Driver with 20A Handling Capability

The project illustrates a unipolar stepper motor driver that is able to handle 20A current.

3-Wire Fan Controller Built with PIC

The project shows how 3-wire fans are controlled with PWM while simultaneously having RPM feedback.

SMS Controlled Light Tower

The project illustrates the use of SMS message to remotely produce cool effects by switching lights.

Arduino Based High Altitude Balloon Tracker

The project is known as Ferret which uses a GPS tracker along narrow band RF tracker in a balloon payload with the possibility of tracking the balloon and tuning up the frequency.
