Sparkfun, an open-source electronics company, and Uverter, an online design tool, have teamed up to bring a massive library of editable and hackable open-source designs to you for free.
Why are these two parties such a great fit? On the creation side, there is Sparkfun. Sparkfun is a company that sells electronic parts, pieces, and kits. It was built on the idea of open-source, which means the company has to rely on being fast and always coming up with new good ideas. When you buy a part from Sparkfun, you get all the information, including schematics and pcb files.
Up next is Upverter, an online pcb editing, simulation, and collaboration tool. In this one place you can design your boards, visualize how they will look, simulate the circuits, collaborate with coworkers, and even send them off for production.
The two seem like a perfect fit. Sparkfun has uploaded over 500 of its designs into the tool so that you can simply log in, select what you want, and instantly be working on your own derivative of their work. Having a library like this at your fingertips is surely a fantastic resource.
