Belt driven electrostatic generators using an exciter circuit and the friction machines and capable of DC lightning. How-to, pictures, text, files, and links.
A Marx Generator produces a short, but very high voltage pulse by charging a stack of capacitors in parallel to a lower voltage and then switching them in series. The switching is usually done by spark gaps.
HV arc transmitters, theory, history and tidbits of knowledge. Excellent source of information.
(Climbing Arc) Construction informative page on these very dangerous devices.
By using only capacitors and diodes, these voltage multipliers can step up relatively low voltages to extremely high values, while at the same time being far lighter and cheaper than transformers.
Description and construction of a Greinacher or Cockroft Walton generator. The site is in French, but a few places are in English.
Salvaging interesting gadgets, components, and subsystems. Including HV parts from hither and yon.
