[sdiy] Touchpad as CV controller

[Veronica Merryfield]

Hey

Most of thee devices are based on capacitive sensing. Check out the Cypress touch microcontrollers for info. There are other micro ranges that now include touch sensing hardware but I have found the data available from Cypress to pretty comprehensive. They do 2D and 3D sensing systems.

I have a number of used notebook touchpads lying around and was thinking about building a CV controller using one of these. Idea is to give trig/gate outputs when the touchpad is, well, touched, and X and Y information would translate as CV Outs, with additional potentiometers for Offset and Scale.
