#350 CircuitScribe/LiteWings

Learning about conductive ink with the CircuitScribe LiteWings kit.



There seems to have been quite a boom in conductive paint/ink applications in recent years. From the (google) research I’ve done - see Conductive ink on wikipedia for example - I don’t see any particular reason for “why now” .. no great materials breakthough seems to be driving the trend. Perhaps it is more a market-pull situation - more people interested in wearables and flexible tech for example.

When I saw the latest Circuit Scribe kickstarter campaign, it was a perfect opportunity to try some out.

I received a simple LiteWings kit recently, and was impressed. After making the wing kits I still have ink in the pen, so now looking for novel applications;-)


It is pretty simple!




Depending on how densly one colors in a “wire”, the resistance can range from 35Ω to 75Ω (as measured on my attempts).

The batteries supplied were CR1216 3V, so no extra current-limiting resistance required for the LEDs.

The circuit is as simple as you can get:

LEAP is my personal collection of electronics projects, usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting (IMHO!).

The projects are usually inspired by things found wild on the net, or ideas from the sources such as:
