That's just a story made up by cowardly enemy soldiers. :)

Has anyone seen any good write-ups on, or figured out for
themselves,
just
how the self-oscillating dirty - i.e. smoothing cap-less -
switchers
that
you find in use as lamp ballasts (or 'electronic transformers'
that
they
seem to be sometimes known as) work ?

I recently acquired a fairly sophisticated disco lighting
fixture that
has
such a supply to run the 24v 150 watt lamp. It seems to have
two main
switching devices, which I suspect are FETs or IGBTs, but
can't tell
for
sure so far, as the numbers have been ground off them. On the
mains
side,


That's pretty high tech for a product from the 1970s to use a
switching
power supply.



1970s ? Where did you get that from ? It's actually about 4 or 5
years
old
at a guess ...

This one seemed to go over everyone's heads.

the joke (and sad truth) is disco never died in europe. All horrible
things last forever there.



Clearly, you don't understand the difference between 'Disco' and
*a* disco
... See my other reply :)



the germans have some of the creapiest musicans that are still
alive and
popular, like Fancy.


Well, that's Germany for you. That's mainland Europe, which we in
the uk,
aren't. Being an island, our culture is rather different from that of
mainland Europeans, although politicians both sides of that watery
divide
seem to have trouble comprehending that. We have some of the best
musicians
in the world, and most of the rest of the world follows our lead ...


It is safe to say good music comes out of the UK on a regular basis.

Bagpipes?


ugh, I hate the sound of bagpipes.


A bagpipe was invented as a military instrument to scare the enemy.

as it was blowing, hot air!

Me, either. We have someone who plays them for Memorial ceremonies
at our Veterans' Park. He is out there a lot of mornings to practise,
and break in new reeds.
