I just saw an article about the Paperduino on the MAKE blog:

Guilherme Martins in Portugal designed an Arduino clone built on a cardboard substrate. The component layout and wiring, top and bottom, are printed on paper and glued to cardboard. You poke holes with a pin and shove the component pins in the holes. Then you wire point-to-point following the printed wiring diagram:

It seems to me that this is a good bootstrapping technique where circuit boards are not available or too expensive. It would also make it very cheap to supply alternative circuit designs if components need to be substituted because of availability or cost.

Well, *technically* you *are* printing circuitry... just not actual copper tracing, but more of a custom breadboard setup.

However, this may actually do better for those who can get the individual bits cheaply, like me. (Skycraft Surplus--you name the transistor, it's quite possibly there! )

Let me know when an Arduino-clone diagram is released, along with a compatable bill of materials attached.

Lemme' know when they get this working for SMT.

ABSOLUTELY amazing!
