Hey guys , making projects easier means having the right tools. Ezb does alot, but it can do even more by making simple circuits. This is a new tool that last year was in beta from the autodesk family. It is available now to use online through the Web or installed on a PC as an application for free. Previously circuits was a independent open source group and still follows collaborative effort among other users. They can share circuit designs and even entire pcb designs. Upgraded account are available with additional features. You may want to weight out the services that are best for you.
