Collin Cunningham teaches you how to etch your own circuit boards using the photoengraving method. No longer will you have to send your designs away and wait forever for your PCBs to arrive in the mail.

Making your own printed circuit board can be a truly satisfying process, tying together electronics and the handmade craft of etching. It’s the most accurate way to build a circuit short of sending away to a PCB manufacturer and it’s a lot more fun (+ cheaper too!).
