Circuit Board Layout ArtworkNote: the new circuit board layout will not have any surface mount components, and it will be made with a silk screen that identifies each part, to make it much easier to assemble.
Parts Placement Diagram. The three dotted parts are surface mount soldered
to the bottom (solder) side of the board. The four analog input sections
are identical (LM324 opamp, two 10 resistors, two 0.01uF capacitors, and
eight 1N4148 diodes). Only the first one is labeled, to avoid a lot of
extra clutter in this diagram.
