CircuitLab: Google Docs for circuits

CircuitLab is an online circuit design tool. This is my new favorite way to jot down circuits. The interface is clean and simple and even has some test/simulation facilities. It also has a sharing/GoogleDocs type feature.

Hopefully they’ll add circuit board layout to their list of features at some point. Fritzing is great, but still not quite as clean as CircuitLab. Perhaps someone can write a CircuitLab-to-Fritzing bridge in the future.
