When developing a new circuit design you will find that you often drop in solutions from previous projects since there’s no reason to re-invent the wheel every time. HackEDA takes this idea and pushes it out to the web, it’s in beta right now so it might not be able to handle all of your project ideas but by clicking a few buttons you can build the basic framework for many project ideas. After you are done you can simply download your Eagle 6 schematic.

Thanks for the tip Ben.

“At it’s core, it’s a system for collecting reusable-sized pieces of electronic designs, along with the knowledge necessary to reuse them in new designs. The library is available to browse online, you can download the individual bits, and there’s also a tool for creating custom circuits by simply selecting the features your project needs.”
