Ballpoint Pen Draws Electronic Circuits With Conductive Ink

Circuit Scribe is a rollerball pen that uses a silver conductive ink to let you create fully functioning circuits as fast as you can draw, making it cheaper, faster and easier to test out electronics and prototype concepts.

Developed by Electroninks Incorporated, a company originally part of a University of Illinois research lap, Circuit Scribe tries to make the process as easy as possible. No wires, no boards, no soldering; all you need is a sketch and you can begin tinkering with nothing more than a coin battery and an LED.

Circuit Scribe offers a selection of components, from relatively simple buzzers and LED lights, to more sophisticated parts like photo sensors and potentiometers. It can even interface with the Arduino MaKey MaKey, allowing for even more elaborate designs and making it ideal for hackers at any level. With Circuit Scribe, you can create everything from a simple switch to a fully functioning touchpad. The water-based ink dries instantly so you can immediately begin testing on a freshly drawn circuit. Read more...
