4-Channel Timer Known as xTimer

The project was design to be suitable with energy saving applications since it has simple hardware and nice firmware with C coding, making this 4-channel timer easy to build.

Testing Tool for LED Component

The project is a standalone LED test tool that is foolproof and very useful for anyone who is into recycling old electronics.

PWM Power Supply with Constant Current

The purpose of this project is to control the current across a load by using pulse width modulation for maximum power efficiency while being constructed on a breadboard.

Ring Light From Surface-Mount LED

The project is a solid-state ring light that incorporates surface mount technology using high-output & relatively inexpensive white LEDs.

Temperature Sensor for Veggie Oil Applications

Cars and trucks that are running on veggie oil would benefit on this easy to install temperature monitor since any veggie oil used in a diesel engine needs to be heated to ideally at least 160°F to achieve a low viscosity.

Modified Power Distribution Unit

The project illustrates a great way of recycling some old electronics by modifying a controller for an old APC power distribution unit.
