Re: [TCML] High Voltage Negative Ion Generator
The Electronic Goldmine (goldmine-elec.com) has them ready built for
$10.95. See item G1783.
I built one 35 years ago with the 7.5 kV negative corona charging supply
from a Xerox copier. They used to be very common at hamfests, but I
haven't seen one in years. You could probably pull the HV section out
of an old copies or laser printer.
Basically, you just need a high voltage negative DC supply that feeds a
bank of needle points to make corona. The current requirement would be
only a few microamps.
