Knitted Oscillator

An oscillator based on CD40106 Hex Schmitt Trigger chip.

Replacing the resistor with a knit made of a resistive yarn or conductive foam. This creates a variable resistor which will modulate the pitch of each inputs. You can make a total 6 different varaible resistors on x1 CD40106 Hex Schmitt Trigger chip.

Another project was made using light sensors (photocell) with calcite rocks to modulate the sound through the light coming through. People can play with the 'rock osicilliator' by passing their hands on the rocks varying the light.
