"Fritzing" Software Bridges Schematics, Prototypes, PCBs
One of the many things that I haven't had time to pursue this year is a determination to do some hardware hacking. One aspect that's been a challenge is moving between the joy of "stick a wire in a breadboard and see what happens" and schematics (I'm sure for the more experience this "challenge" is long forgotten). Fritzing is a piece of software on which you can drag-and-drop wires and components and it will show you the schematic (and vice versa). Kewl.
