A website which lets you design circuitry online in your web browser (i.e., without having to (buy, download and install PCB engineering software). The online circuit designer contains a library of known, documented, and trusted subassemblies of circuits (like power supplies, amplifiers, and volume controls) that you can use as the framework of your circuit, but you have to add the rest. They plan on making it possible to automatically generate and e-mail all of the files a third party small-run manufacturer would need to etch, drill, and mail your circuit boards to you.
