I can remember the lovely lilac corona you could get when you poked the end of a screwdriver *near* the tripler in a CRT set. Tens of thousands of volts going *almost* through you (more like around the outside of you, rather than through your innards), but you were the conductor, though you couldn't really feel a thing. There'd, also, be a rather ominous screeching noise from the electronics.
i know that feeling. similarly, i had a skin effect experience when i put my hand on a van de graaff generator at the Chicago Museum of Science and Industry. [as a side note, i know the man, Steve Worack, Circuitron, Inc., who built the model railroad exhibit. a neighbor from when we lived in North Riverside, IL.] not so good a feeling was having touched the low voltage rectifier in the high voltage section a a tv with palm of my left hand. that went straight to the bones in my hand and exited from my foot thru 3 nails in heal of my shoe to a floor furnace. i had the burn marks in both for well over 40 years. if you want to reminisce about tubes; http://en.wikipedia.org/wiki/Vacuum_tubes http://en.wikipedia.org/wiki/List_of_vacuum_tubes i still have my first and last RCA and GE tube manuals stored in my historical storage boxes along with my RCA and GE semiconductor manuals. hell, even a lot of my ic manuals are now outdated. i guess i will have to do some relabeling of the boxes. :=) it is a shame that most of 'tech heads' of today know very little of such, thanks to the needs of the aero space rocket launches. sure would be nice if fedoraproject would create a 'general' list like mozilla did. then reminiscing would not be a thread unraveler. ;=) -- peace out. in a world with out fences, who needs gates. sl6.3 linux tc.hago. g . -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
