We quite liked the trick of using old PCBs as capacitive touch sensing, using copper fills ... [Jeremy]’s got a whole YouTube channel you ought to check out. Oh, and if one of the musical ...

Using multi-material 3D printing and computational tools, this work demonstrates an approach to generate and fabricate conductive traces within objects to support capacitive touch sensing. Touching ...

The idea is that simple resistive or capacitive sensors can be read through their AC characteristics by sending out a sine wave on one channel of the card and reading the result on the other from ...
