This week I teamed up with Xander Hudson to make PCBs. Besides being pretty, making your own printed circuit boards is fun and you can have a prototype board ready in a few hours.
First you need a design. There are a bunch of timer circuits in the latest issue of Make: that are begging for circuit boards. There are lots of designs online at places like discovercircuits.com
Eagle CAD has a bit of a steep learning curve, but it’s got a library of parts that you can drag and drop onto the board that make getting everything the right size and proportion easy.
If you don’t want to design your own circuit, you can download all the source files, including a pdf, and print them out on a laser printer out to make the Make: Light. – Link (Zip File)
Also, make sure to download the pdf that goes along with this podcast that includes a great article by Andrew Argyle that includes material lists and step by step instructions. – Link
