Re: Cheap high voltage

If you put one at every station you'll need to be sure that the current
they can supply is VERY low or they are well screened. Remember the
fingers that may get poked into the supply. It would be a shame to stop
somebody's heart. WBN

American Sci & Surplus is selling 7500v power supplies for $7.75.
These
are *AC*, but are sold as "Ionizers" with a needle strip. Perhaps they
are
current-limited, but I can't really tell from the description. It's
on
the back page of the new catalog, #28701.

Build two of them into a box, each with a 20KV diode in series, for a
pos-neg electrostatic power supply? At these prices you could put one
at
every student station in the lab.
