improve sensitvity #15

Closed mindforger closed 7 years ago

mindforger commented 7 years ago

one thing in advance, i am not profesional in things like electronics but i talked to a co-worker beeing professional and asked him if i could probably get better sensitvity on this

he told me you could mirror the capacitor layout on both sides of the PCB and connect the planes with a few vias, this increases the overall capacity coupling over the surface and greatly reduces the coupling through the PCB material itself, resulting probably in an overall capacity loss but a great improvement on capacity change through the surface field

Thanks for the tip! I am not sure if there really is any need for more sensitivity for now.
