Hello I really like the forum here, and apologies for any redundancy in previous threads. I didn't find any answers in recently posted threads and didn't want to bump a thread that was too old. I'm looking for a simple way to make a small electrostatic precipitator for use in a small enclosed box by giving a plate or interior of the box an electrostatic charge strong enough to hold on to dust-like particles of a relatively large size as far as particles go, about the size as some of the larger particles in household dust but with a little more density. From what I perhaps incorrectly understand, metals aren't suitable for this purpose because of their conductivity. I am also aware of the obvious solution of rubbing a piece of fur or carpet on the surface, but I'm curious about automating and if possible maybe even adjusting the intensity of the electrostatic charge on the plate. If anyone could help point me in the right direction, give me some tips on how to start, if this is even something that can be accomplished in an economic manner, I'd be very willing and happy to document its construction in this thread as a demonstration to others who, like me, are interested and less knowledgeable in this area. Thanks!
