This is the Circuit Scribe Conductive Ink Pen, a simple looking ball-point pen that allows you to draw circuits instead of soldering or wiring them to a breadboard. With Circuit Scribe you can draw exactly what you want, no wires or breadboard required. You can build a circuit with nothing but a coin battery, paper clip, and LED, or build out complex circuits with multiple components. The Conductive Ink Pen uses a non-toxic, silver conductive ink that writes on any surface a regular rollerball pen would with a resistance of 2-10 Ohms/cm.

The main conductive component of the conductive ink pen is a silver-copper mixed powder, which also contains an appropriate amount of an oily thinner, a film-coated resin, and a conductive agent; the conductive property is excellent; the paint is liquid and has strong fluidity, and it can conduct electricity after being air-dried after painting.


How to use the conductive ink pen?

The use of a conductive ink pen is similar to the use of correction fluid. Shake the pen well before painting. The iron column in the pen body can fully shake to prevent the paint from depositing. The pen body is slightly vertical. The handwriting needs to be plump and smooth.
Shake the pen body sufficiently before use to prevent the precipitation of metal powder in the paint.
Make the pen body slightly vertical, press the pen tip lightly on the plane, squeeze the pen bar and drag slowly, and the handwriting needs to be plump and stable.
After the pen handwriting is air-dried, the conductivity can be measured with a multimeter.
1. We can imagine the lines painted with conductive ink as liquid wires, and we can draw vivid circuit patterns with our own ideas.
2. In addition to painting with a dedicated conductive pen, you can also use a brush, roller, etc. to paint like paint.
3. The conductive ink can adhere well to common materials and is not easily washed off by water. If you don't want to remove your work and want to make it more durable, you can spray a layer of varnish on it.
4. In addition, you can also cover some of the insulating material on the drawn circuit to draw a multilayer circuit.
5. If the first painting fails to conduct electricity successfully, you can repeat the painting after the surface of the first layer of ink is dry. Using a hot air gun can speed up the ink drying.

Where is the product suitable?

The conductive ink pen has excellent performance and can be applied to various occasions according to different needs. conductive ink pens are often used for creative circuit doodles, such as electronic greeting cards, paper circuit painting, etc., and can also be used for simple circuit repair.

Why choose a conductive ink pen?

Safe and reliable, no welding required; easy to understand and easy to learn; fun and entertaining; diverse gameplay, wireless imagination! Let’s enter the wonderful electronic world together!

Which materials are suitable for painting?

After the paint is dry, it can adhere well to cardboard, wood board, glass board, acrylic board, PLA, ABS and other materials. We recommend using thicker boards. Hard boards can effectively avoid the breakage of painted lines open circuit problem.

Why doesn't it conduct electricity after painting?

The conductive ink pen is of good quality, and it is impossible to be non-conductive after painting and drying under normal use. If the handwriting is non-conductive, it is mainly because the user has not used it properly or the brush stroke has not reached the path conditions. Please refer to the following pictures:
