SCALAR ELECTROSTATIC GRADIOMETER

[ivconic]

A friend send me a link to this schematic. He insist me to make prototype and perform some checks and experiments. I told him my opinion and explained him my attitude upon simillar projects. Yet...he insist and i decided to obey his wish and to please him by making this. Just draw preliminary pcb for this thing. Have not much spare time so i decided to draw fast and easy pcb just for prototype. If this turns to be interesting than, later i am planing to draw much better pcb.
Ok...since this corresponds to subjects in RS thread i decided to post it. I would apreaciate any comments and reactions on this. Although i already do know what to expect...
