I had my revenge on my unfriendly classmates at school with a Van de
Graaff generator.  ;-)  While they were all daisy-chained to each other,
standing on plastic boxes, with one on the end touching the generator,
as part of a practical demo, I grabbed the water pipe and the person on
the other end.  They all sprang apart in a hurry.

I hate switchmode power supplies.  Electrically noisy, high voltage,
high current, painful operating frequencies, or DC, live heatsinks...
You have to be damn careful working on them.  I'm not sure which is
worse, them or TV set EHTs.

Yes, if they hadn't needed to cram a computer into a tiny space capsule,
and had the money to fund the research, I don't know how long it would
have been before we got ICs.

George Orwell's '1984' was supposed to be a warning against tyranny, not
a set of instructions for supposedly democratic governments.
