Very interesting build! I'm trying to build it myself. How were you able to invert the polarity of one half of the pumps? I might be wrong, but the schematic you provided doesn't seem to reflect that. It shows all the pumps are connected with the same polarity. Could you elaborate on that? Thanks a lot!
