hi I'm stuck at home bored out of my
brain and for future people who are
watching this video it's during 2020
pandemic and everyone is stuck at home
trying to flatten the curve so I was
just looking at these flames and thought
to myself is this a microphone is it
possible that the FBI is spying on us
using our lighters no no hear me out I'm
not totally crazy yet this might be a
microphone because it has a appears of
crystal in it now if you want to know
how piezo effect works go watch steve
moulds video who describes it in crystal
level but in general appears of crystal
if you apply voltage across to specific
surfaces it contracts or expands over
reversely if you push and pull on the
crystal it generates voltage across it
so it can act as a load and if you smash
it it can also act as a generator and
provide some power now it's made of
different material like ceramic is one
type yeah like ceramic quartz langa site
which is la3 g85 SiO 14 doesn't matter
so this thing has piezo crystal in it
and it hammers on top of it so hard that
it generates very high voltage that
generates arcs in the tip I don't know
can you see that all sorry hammering it
hard could create five to ten kilo volts
but we don't need such huge voltage for
audio signals I'm guessing even my voice
vibrating it could create decent audio
signals so it could be a microphone
let's see if we can be Samantha lit and
get to the wires there you go so there
are two contacts one here connects to
the metal body and the other one is the
tip here now if you like to feel some
electric shock this should give you a
very mild one yeah it's more of a
surprise that what yeah it's not too bad
shocking now let's see if I can record
any audio from it
I hope it wouldn't look too stupid that
I will be talking into a lighter I'm
gonna find a broken headphone and
connect the lighter wires to the
headphone wires and record audio
hopefully there we are an audio jack
typically there are four wires in a
headset cable and this green and red are
their stereo left and right and the
copper colored one is the ground and in
my case this one is extra I'll connect
the ground to one side of the piezo and
tie the two channels and connect it to
the other side so both channels would
have the same audio input now to avoid
being an absolute idiot and damage my
devices audio input I put two parallel
reverse diodes between my signal wires
to limit the voltage between them below
point seven volts now all I need is to
connect the piezo output across my wire
and the only audio recorder I have right
now is my camera's input so I'm going to
record on the other camera and slap like
if you hear anything well I guess FBI is
not spying on us through our lighters
that's a plus I was hoping there would
be at least something let's measure this
thing so noisy well let's try with
something look at that I'm not an
absolute idiot sure let's crack this
open you might be able to make it better
hmm
there you have it the piezo keeps out
and it typically looks like this this is
one contact of the piezo and this wire
is the other side look how much more
sensitive it is now that I pulled it out
I'm thinking if I glue a large membrane
to it it might pick up the air
vibrations better here it is let's see
if it works any better
it works but who saw a lighter can be a
microphone
we have been bugging our homes with
lighters let's see if I can record on my
camera now
well surprisingly it's not made to be a
good microphone when I connect it
directly to the camera the camera
voltage and input impedance loads it to
zero
so the output of this has to go first
directly into an amplifier to be strong
enough and now I'm trying to see if it's
a speaker and when I connect it to a
function generator or I can hear it very
faint noise I don't know if you hear it
at all or not I'm gonna make it work one
way or another I'm gonna make an
amplifier and feed it into it okay I put
an amplifier together and seems like
it's working to some extent I just hook
it up to the camera and see what happens
and that's not all they are trying to
kill us slowly by excessive radiations
the best solution to that is to stay
inside because your home walls you know
filter radiation to big extent and it
also helps with the current pandemic so
stay home
