This is a rollerball pen that writes with conductive silver ink. It makes creating circuits as easy as doodling.

The Circuit Scribe conductive ink Lite kit comes with a pen, a Bi-LED module, and two coin cell batteries. The Lite Kit is great for simple circuit projects including studies in conductivity, basic logic and open and short circuits, among other things.

The Bi-Directional LED module works in two directions. When current flows through it one way, the LED will be blue; flip it around and it will turn red!

You can use a Circuit Scribe pen to draw lines on any simple piece of paper, then attach special electrical components (Circuit Scribe modules) on the drawn lines which allow the electrical current to run through the components. This replaces the use of breadboards and wires.

Use it on any surface a rollerball pen will write on. The Circuit Scribe pen can draw 60-200 meters depending on writing surface and speed. 60 meters is seen on absorbent surfaces similar to a napkin, and 200+ meters on photo paper. Photo paper also has other benefits: you can erase ink by scratching a trace away, and you also get the highest conductivity on this surface (<2 ohms/cm). Soldering to the ink is possible - but tricky - and greatly depends on paper/surface type and solder type.
