Connect both potentiometers to a 12V DC
transformer that’s rated for a total amperage
greater than the sum of the amperage of all your
fans combined.In our fog screen we have 14 fans
at 160mA and one at 100mA, totaling2340mA,
powered by a 12V 2500mA transformer.We were
lucky and sourced the transformer from an old
laptop but various 12V transformers with the
needed amperage can be found on Amazon.
Finally, make the fog skirt.Previous DIY and
commercial fog screens have focused on
laminar flow of the air from the fans to keep the
fog in place. That’s awesome, but it adds too
much weight and ...
