Arduino Skeleton – Look Mom, no PCB!


MAKE subscriber Kakehi spotted this unusual Arduino incarnation at a recent Make: Tokyo meeting – Kimio Kosaka’s Arduino skeleton, made from nothing but components, steel wire, solder, and loving care. The board design is based off of the Metaboard Arduino-(mostly)compatible, which implements USB compatibility in the chip’s firmware.

Hmmm … insulated standoffs anyone? Maybe a quick resin dip?

    In the early 60’s missile modules were built in a similar manner, then encased in a solid block of epoxy resin, for shock resistance. The big difference: They didn’t solder, instead they SPOT WELDED each joint. You could see the “dents” where the wires crossed and were joined. (a coworker had most of a rejected unit as a paperweight – they would bandsaw the connector block off the rejects, so they were sure that they wouldn’t get flown)
