Make a homemade PCB all by yourself

Printed circuit boards, PCBs, can be made from a variety of substances. The most widely used in a form of glass fiber based board known as FR4. This provides a reasonable degree of stability under temperature variation and is does not breakdown badly, while not being excessively expensive. All electronics utilize circuits as a means of transmitting and using electricity, so anyone interested in electronics as a hobby or career should familiarize themselves with circuit boards.

Fortunately, constructing a homemade circuit board is a relatively simple and straightforward task. With some basic tools and a few hours to spare, anyone can build their own circuit board and create the foundation for a much deeper experience with electronics.

Instructions
Making a Basic Printed Circuit Board
Step 1. Drawing the circuit pattern on regular paper with a pencil. Mark where you will need to drill holes.
Step 2. Place tracing paper over the first sheet and trace the pattern with the overhead projection pen.
Step 3. Tape carbon paper to the copper side of the copper clad board. Neatly tape the tracing paper over the carbon paper.
Step 4. Once again trace the pattern with the overhead marker. Remove the tracing paper and carbon paper; the marker's ink will leave the pattern on the copper board.
Step 5. Wait 10 minutes for the ink to dry, then place the copper board in a container, and submerge it in the etching solution. Allow the board to simmer in the solution for a couple of hours.
Step 6. Clean the board with tap water.
Step 7. Drill holes where components will be attached.
Step 8. Use thinner to remove the remnants of the marker ink. This completes the basic structure of the circuit board.
