BETA Warning: for serious tinkerers only. CIRCUITS.IO is hoping to reduce the complexity in building, designing, and discovering circuits. Young makers and engineering students will appreciate the in-browser circuit building tool. DIY electronics gurus can take it a step further by starting a “Bootstrap Campaign” to get their most interesting projects off the ground. In the spirit of open source hardware, each circuit design includes a list of required components and a free downloadable Gerber file for tweaking or manufacturing PCBs.
