Circuit Scribe 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 presents, while improving your understanding of different ways to input, process and output signals in your circuits. Additional topics to explore include light, timed circuits, piezoelectric materials, and more.
