Circuit Scribe is a rollerball pen that writes with non-toxic conductive silver ink. It makes creating circuits as easy as doodling. We've created a non-toxic, silver conductive ink pen and a number of interactive modules. The Maker Kit contains a pen, eleven modules, a 9V Battery and other accessories to improve your circuit drawing experience. This kit allows you to explore all of these concepts: knowledge of transistors, resistance, elements in parallel and series, open and short circuits, and improves 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.
