- A Van de Graaf generator is built for the purpose of creating high
- voltage static, emp, and electrical transients. Playing with one in
- the vicinity of computers, stereos, tvs, vcrs, or any other sensitive
- electronic equipment is ill advised.
-
- The question is roughly equivalent to asking, "I have built a large
- blowtorch. How may I play safely with it around gasoline?"
- It may be possible to take enough precautions, but the main
- precaution to take is to just say "No!"
-
- Analog tube gear was leading edge at the time these generators were
- and generally recovers from transients quickly. Solid state
- digital is not like that.
