This is a rollerball pen that writes with conductive silver ink. It makes creating circuits as easy as doodling.
The Maker Kit contains a pen, eleven modules, a 9V Battery and other accessories to improve your circuit drawing experience (see below for full list). This kit allows you to explore all the concepts that the basic kit does while improving your understanding of different ways to input, process and output signals in your circuits. Additional topics to be explored include light, timed circuits, and piezoelectric materials, among others.
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.
