Circuit Scribe, a Kickstarter project aiming to make it easier to prototype electronics, has designed a rollerball pen with conductive silver ink inside that lets you doodle circuit designs on a piece of paper.
After the super slick Ex1 circuit board 3D printer, say hello to Circuit Scribe: another Kickstarter project aiming to make it easier to prototype electronics by doing away with breadboards and soldering. But this project is taking a deliberately low-tech (and thus low cost) approach — by putting conductive silver ink inside a rollerball pen so you can doodle circuit designs on the back of an envelope.
