The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.
I'm prototyping a hand-held 110V tool. It has a filter screen where the usual dust and debris collects. Is it possible to create a static discharge that would "kick" off the dust particles? Can't use vacuum or any other method.
- Is it possible to cram the neccessary components into a small enough size for a hand-held power tool? - Any safety issues to be concerned about?
Ah thanks Sulaiman. What are your thoughts on the size of the electrical system; how small you could make it, and the best design for this application?
We're talking about a half a teaspoonful of dust, removed every several seconds or so. Could the secondary grid stand off from the primary about, say, half an inch?

That would depend on the mass/composition of the dust, the relative humidity and power available. Safety isn't that big of an issue-- you'll still need kV for the E-field, but the overall power level probably won't get anywhere lethal; just use common sense. But if this tool is being sold to Joe Public, I'd expect this part of it to be vetoed by the insurance people.
Coyote, the dust would be your normal sanding dust - it's on a sander. So a power source is always available. If you were me, where would be the next place to get some components for prototyping? You can tell I am a newbie in this area.

My Canon D400 has a piezoelectric element attached to the CCD which is supposed to shake the dust off. Don't know if it works or not but you could prototype and try something similar

Electrostatic dust kicker?
