Always accept free plywood.

Structural plans got scrapped for fear of structural instability.

Instead we built 18 11"x11"x4" boxes.

We have a working V.1

The sensors are not as sensitive as I would have hoped.

The first issue i ran into is that I assumed that an Air gap would be equivalent to the cardboard capacitor of the prototype. This was not the case. In order to get my capacitance to ground closer I used a sheet of laminate. This got the pad functioning. From here i can A an 8 while barefoot, but not AA. I'd say 1/250 steps appears to be off by ~160ms or is a clear pad miss. It only kind-of works with shoes. The issue has to be that I have too much noise / Signal is floating. I have a plan though. different / better dielectrics and a physical capacitor on the board in parallel to my laminate capacitor should solve this issue.

I'm also getting some pad squeak on some of the sensors. I have some things that i can try for that as well.

Will post instructions when I'm happy with it.

Thanks for your patience!
