[James Eckert] got his hands on a Freescale MPR121 capacitive touch sensor. The chip in question speaks I2C and senses up to twelve simultaneous capacitive sense electrodes; break-out boards are ...

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 ...

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 ...
