This is the Circuit Scribe Conductive Ink Pen, a simple looking
ball-point pen that allows you to draw circuits instead of soldering
or wiring them to a breadboard.
With Circuit Scribe
you can draw exactly what you want, no wires or
breadboard required. You can build a circuit with nothing but a coin
battery, paper clip, and LED, or build out complex circuits with
multiple components. The Conductive Ink Pen uses a non toxic, silver
conductive ink that writes on any surface a regular roller ball pen
would with a resistance of 2-10 Ohms/cm.
