The disc with the holes is chemically photo lithography etched , still = expensive! If my memory is correct the etched material was in the neighborhood of $900.00 per 22" x 22" section.
I did finally get some of the video out, but being mad didn't help, I lost a bunch of it to rerecording without realizing with the cap on. I did get the some of the last cell configuration, though it was after it was up and running for a bit. I'll redo the whole thing again after the new cam comes in.
This may not be active yet, but will be soon.
