[Bertho]’s submission for the 74xx logic contest is really impressive. He designed a capacitive sensing touchpad using only 74xx and 40xx logic chips. We’re impressed with the build and his ...

[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 ...
