Bare Conductive Paint Pen: Electric paint. Nontoxic, solvent free and water soluble. You, your child can use it to draw circuits, solder components even do repairs. The pen creates a "liquid wire" that will conduct electricity from your power source to a circuit. Works on traditional electronics, plastic, paper, cardboard even textiles and is compatible with conductive thread, PCBs & microcontrollers such as Arduino, Raspberry Pi and FLORA. Conductive when dry. Comes off with soap and water.
This is the stylus that provides enhanced precision and control while drawing or writing on all Apple iPad and iPad Pro models. It employs advanced circuitry in combination with a replaceable 2.8 mm conductive PET tip that flexes and glides across a tablet, enabling pointillist detail while drafting or doodling. Comparable in size and feel to its ink-filled cousins, the pen is ideal for outlining a sketch or crafting legible notes.
Conductive Ink Pen Lets You Draw Custom Working Circuits - Instead of wires, soldering, and a lot of specialized knowledge, you can draw circuits on paper with the non-toxic, water-based ink. Circuit Scribe sells modules that you can snap onto your creations with magnets to make working lights, sound modules and even a small motor.
Electroninks Incorporated is raising funds for Circuit Scribe: Draw Circuits Instantly on Kickstarter! Circuit Scribe is a rollerball pen that writes with conductive silver ink. It makes creating circuits as easy as doodling.
