Hi,
It´s not a matter to laugh about what happen to
me
I am occasonally do some demonstration in a
vacational school with a simple spark transmitter.
Such a Xmitter can be easy built with items
from Leybold. Leybold furnised schools physics - store rooms but many teachers
dont know what treasures in there especially for radio.
So I built with a high voltage transformer, a
multible spark- gap, 2 huge Leydener bottles ( 2 x 500pF ), a primary coil ( 10
wdg) and multiturn secondary coil as Tesla transformer connected.
There was also a strange looking bulb which was
filled with a unknown gas ( discover later )
As I did the first test the transmitter works as
there was a very loud crackling noise in the multiple spark gap, accomanied with
a lot of sparks a blue-ish- red sparks in and arround and from the top of the
tesla coil.
So fare so good. that was the test.
Next day ( Professor Ferdinand Braun Day ), the
auditorium was full with students and press, I showed first am simple
" Wagnerscher Hammer" ( it is similar to a
old door clock ) with some sparks at the interruptor.
The response was feeble.
Then I pullt out the surprise.
I let dim the room and forced the students to go
mor away and started the Tesla- transmitter.
You may imagine what happen with all that sparks,
the noise, the coulors, the smell of ozon and the illuminated gas
bulb.
In one corner of the auditorium where suddently a
rumor, because all Pc stalled.
For me and all Hams, we know what happend ...
beside the sparks where also produced EMF- pulses, strong enough to stop the
processors from work.
What would happened, if I would use more power
?
You may know the answer

( next Professor Braun Day will be 16/17 Sept
)
