Small PCB for rotary switch and a few resistors, to make a custom-taper stepped potentiometer
While I was breadboarding the SN94281, I decided it would be a lot easier if I had a quick and easy way to switch between different capacitor values, so why not practice PCB design by making a capacitor switch. The design is inspired by this Sparkfun potentiometer switch. However, instead of stepping the capacitance, my switch simply selects one cap at a a time.
