Adjustable Power Supply

Objective

The goal is to build a circuit with an adjustable voltage and current for use in various DIY projects.  Initially I intended to build this based off some references I found on the internet but then Lady Ada saved me.  She has a great tutorial and kit for exactly what I wanted.
