O/T Spark Gap Transmitters was: Interest in UUCP?

Has anyone else here tried using metal screen, etc. with such devices for interesting effects? I won't caution anyone on being careful, since I would think that all of those who post here and are mad enough to also collect and restore vintage computers are intelligent enough to be careful with high voltages. :-) Getting back on topic, has anyone here used a classic computer to control high-voltage devices such as Tesla coils and jacobs laddrs, like the control center for a mad scientists laboratory? -- Copyright (C) 2001 R.
