Adjustable Portable Power Supply

Objective: Build a cheap, portable, variable DC power supply.

Motivation: It was finally time to get my hands on a variable power supply for my electronics projects. Previous projects mainly involved Arduino, which was able to supply 5V and 3.3V with ease. However, the need for a supply with higher voltage, current, and flexibility eventually arose, resulting in the birth of this ghetto (but functional) power supply.
