Take a look at the above

to read this tutorial.
           PCB's also known as printed circuit boards are the backbone of any modern day electronic device. They offer the microscopic wiring and pin point accuracy between IC's and components necessary to achieve the extraordinarily small sizes that we see in consumer devices today.
           This tutorial will go through how PCB's can be etched at home using a 3-4 decade old method. Old methods are often tried and true, which means they leave little room for error as they've long been perfected. The name of this method is 'toner-transfer'. Laserjet ink will be transferred to the PCB and etched from there.



The Final 1 Layer PCB Board

Some Of The Necessary Parts

Purpose & Overview of this project
           The goal of this tutorial is to teach you how to take a circuit drawn in a fabrication program like Altium or Eagle and make it a real-life PCB. To accomplish this we will need about $20-25 and a few hours of spare time.
           The board to be created will be a voltage regulator board, while variable supplies will be used, it will be designed for 4 different output voltages that should remain constant. +5v, +3.3v, 2.5v and 1.25v are the required output voltages from this board.
