Bench-Top Power Supply Construction

The purpose of the project is to build a power supply that is capable of supplying a variable voltage output from 1.5V to 12V.

Breadboard Power Supply with Adjustable Feature

The project illustrates how an adjustable breadboard power supply can be built entirely from Radioshack parts on a prototyping breadboard where multiple voltages can be provided directly to power rails which will be useful for people with low budget.

PC Power Supply with 13.8V & 5A

The circuit of power supply for PC works with a mains voltage of 230VAC to produce an output of 13.8V at 5A due to rectification.

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.

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.

Handy Power Supply Module in a Breadboard

The project introduces a newly improved breadboard power supply with additional header pins to bring power out to both sides of the board while adding some extra stability.
