hi I stumbled upon this video talking
about a circuit called slayer exciter
that supposedly generates very high
voltage the circuit is very very simple
in this video with a link provided below
the guy talks about how to make this
overly simple circuit which is obviously
a fake if you listen closely the
secondary coil you will hear that the
guy actually has an accent if I
determine of course you can never trust
a guy with an accent if the primary with
also the bulbs light up too bright for
such a puny circuit this circuit is all
over the web and people make it sound
like it actually works but a quick
analysis of the circuit shows that this
circuit relies on a feedback from the
secondary winding of the transformer but
the other end of the secondary is not
connected anywhere it's open circuit and
can't affect the transistor but some
people so firmly believe in this circuit
that I just had to make it to put an end
to this here is a transformer I made
which I wanted to use to make a Tesla
coil
I made my simple circuit connected here
and I will turn it on with my power
supply here I turn on the supply see no
sparks there is not even a high voltage
here that they can feel so it's
impossible for these to excite a
fluorescent bulb
was it wrong but I'm never wrong well
you're pretty much always wrong pretty
much always shut up well I guess I'd
have to apologize to my friend I'm sorry
to my defense he didn't have an accent
after Internet and I pour our brains out
we realize there was in fact an
important component missing from the
schematics which is this parasitic
capacitor that exists naturally between
the secondary winding to ground it is an
extremely small capacitance but is
enough to close the loop and make a
circuit oscillate so the circuit can
generate very high voltage in order of
thousands of volts that can excite the
fluorescent material inside the ball
what before you start babbling about
that there is high voltage and you touch
it and you don't die so it must be the
current that Q is not the voltage I
should say please stop being a [ __ ]
volt
joel's current Q's who came up with that
crap yes there is high voltage here now
but it can only deliver very little
current which means that we cannot
maintain its high voltage if more
current is drawn see if I bring my hand
close to the coil even without touching
it some of the energy is absorbed by my
hand which causes the voltage to drop so
much that if I touch the coil the
voltage drop to zero from thousands of
volts and the light goes out as I
measured this circuit has a resonance
frequency of one megahertz now I want to
boost this circuit here is my new
circuit which is pretty much the same
concept but beefed up please see my
website for more details let's try the
beefed up circuit now Wow much bright
most satisfaction the light is actually
getting worn this is what's called
wireless power the power supply is
spending energy to turn on the light but
if I bring my hand between the coil and
the light my hand blocks and absorb some
of the energy and the light goes dim am
i getting cancer from this if I bring my
finger close there are some sparks that
burn my finger but they don't have any
short-term effect in general it's better
to isolate yourself from harmful
electrical signals now I bring a ground
wire cloves see because of the very high
voltage the charges start flying from
the tip of the wire when I touch the
piece of wood with the ground wire the
charges find a way through the
and here's a napkin on the secondary
winding Russia this circuit can be
further beefed off
