One of the things that I find annoying about most of the probe designs is that the rods must be insulated from each other because they form part of a series circuit connecting all of the balls in a chain.
It occurred to me that the rods could all be grounded if logic connected to each of the balls could tell when they were grounded through the rods. So, a probe hit would be recognized if any of the balls was not grounded.
I think that the total cost of this would be a handful of diodes and resistors.
I'd like to find some PC board material that is thicker than the usual 1/16 inch. Does anyone know where I could find some material that is 3/16, or so? Single sided would be most convenient.
As an alternative, I could glue some standard laminate to some aluminum (in some ways, that would be even better). Any suggestions on an adhesive to use? The main requirement is that it must be stable (It would be convenient if it were an insulator, also.)
