This week we are starting in on a series of videos that are pretty different from the past few. Most hackers go through a phase where they etch their own circuit boards. This lasts for a few projects until they need to use a surface mount part, need many circuit boards to be made, or just don’t have the time needed to do everything themselves. In this video [Jack] starts a multi-part series about how to use Eagle CAD, which is a program that allows you to design your own circuit boards that you can then send out to be manufactured. Eagle CAD has a free version of their software that fits just perfectly with a beginner’s budget. There are other free layout programs out there but this one is arguably the best. Eagle CAD has a steeper learning curve than others but has some pretty powerful features to justify the extra effort that you have to expend to get going with it.
This video starts showing the schematic and library portions of the program. We have also added several supplementary videos on our YouTube channel that explain some of the tools in the tool palette in greater detail.
