sensors Touch Sensor Workshop with Mark Frauenfelder at Engadget Expand

Painting circuits with conductive ink.

If you make it to Engadget Expand in New York this weekend, check out Mark Frauenfelder’s workshop Sunday, Nov. 10, from 10-11am. He’ll be making a simple circuit using a 555 timer chip, an LED, and some wire and then creating touch sensor pads by painting them on a piece of paper with conductive ink.

Once the paint dries, you hook it all together and watch the LED light up when you complete the circuit by touching the sensor. You will learn how to build the basic electronic circuit as well as tips and tricks for designing your own painted tough sensor.

What’s Engadget Expand? It’s tech conference for gadget geeks and an opportunity to hear from consumer electronics luminaries and to get a first-hand peak the latest new devices. If you can’t attend, not to worry. We’ll be posting video highlights over the course of the weekend.
