Circuit Scribe Pen

Available online only. Limited quantities available.

Let your creativity merge with science and let your imagination run wild as you build exciting circuits and draw your own connections using Circuit Scribe’s conductive ink pen, magnetic modules (sold separately), and paper. This conductive silver ink pen allows you to doodle working circuits that power blinking lights, whirling motors, beeping buzzers and more.

Draw on any surface a rollerball pen will write on. The Circuit Scribe conductive ink pen can draw 60-200 meters depending on writing surface and speed (60 meters on absorbent surfaces like 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.
