Hi! I completed My OneTesla kit assembly
and I'm Excited to try it together. Let's dim the lights. You should always Keep a proper distance from Tesla coil. Let's play Pink Panther.
WHUUAAAAAUUU!
[F***]!
[BLEEP][BLEEP]!!
My f***ing brain cells!
According to their manual it is better to stand like 10 feet away. Who knew?
Let's run a single tone with a lamp on.
[PAINFULLY LOUD ELECTRONIC TONE]
[F***]!
This is loud
See like I said in my previous video the output power is interrupted at a certain frequency
which I can tune using this interrupter. It's like punching air at audio frequency which makes this sound.
[ANOTHER PAINFULLY LOUD ELECTRONIC TONE]
OUCH!
[S***]!
[PAINFULLY LOUD ELECTRONIC TONE CONTINUES]
Sh**
Playing music might be better.
[PINK PANTHER THEME AT MAX VOLUME]
[painful electric shock and bleeping]
f***!
F*** Why does it feel different? It feels like an actual painful electrical shock
unlike my old Tesla coil. If you remember my old one when I touched it directly, it would just burn my skin
or if I touch It with a metal rod I wouldn't feel anything. This is different I'd like to measure the output
waveform of the Tesla Coil and for that I created a single loop on my probe that will pick up the electromagnetic energy
radiated into the air by the Tesla coil and the oscilloscope will show it. Also I have a ground rod here that the arc will jump
to and hopefully not to my scope. Let's try it.
[SUPER LOUD ELECTRONIC TONE AGAIN]
See? We have pulses of energy!
[SUPER LOUD ELECTRONIC TONE]
So what We captured is that at one kilohertz setting we have a pulse every one
Millisecond and the pulse duration at maximum setting is around forty
Microseconds and the resonance frequency is around 300 Kilohertz. So that's why this arc hurts like s***
See my old Tesla Coil I had a continuous stream of one Megahertz Signal Which Would not penetrate inside the body due to
Conductor Skin Effect, look It up. The Skin Effect is when the flow of Electrons is Pushed to the outer
Skin of the conductor due to the
Electromagnetic
Fields Generated By AC Currents The Higher the Frequency the Thinner That outer Skin Becomes This thing pulses Energy at
Frequencies Lower Than one Kilohertz Which means it has strong Low Frequency Harmonics that Will penetrate deep inside the Body and is definitely Harmful
So never try to touch This at home. I'll give Away four of these at the end of the video so you can exercise not
Touching It at home. Let's Try touching it one more time for science
Let's use the rod!
Using this rod at lower frequency I can still feel it tingling my muscles and nerves but it's much less painful Because the electricity is
distributed over a much larger surface
Let's see if it can turn on a lighter
****
I need a Faraday Cage
Well The Faraday cage Is a Metal cage that Encloses the body completely
This is Just a metal foil Mostly open that i'll connect to ground so that The Arcs Jump to It rather Than Going Through My
Body. Okay here we are my metal glove Connected to ground.
There we go!
Yeah!
There we go!
Now I'm wondering if My spinning Wheelie thingy will work on that
So I bent this wire in shape and I'll place it on Tesla Coil. Okay let's balance It down of course
I expect it to turn much slower than mine, because in my Tesla Coil I had a
Continuous Power Output but this is a much lower duty cycle arc. Let's Try it
[More of this painfully loud electronic tone]
Oh yeah! It's going!
[This is so hard to listen too]
XD [Electric Train Sounds] XD
Let's Instead Play Some Music
[Head shaking and finger snapping music!]
Okay let's get back to the circuit and try to understand how it works. First the Tesla coil itself which is the heart of
Well, Tesla coil it's just a transformer made of a primary with a few turns of winding and a Secondary With
1500 turns in case of This One Tesla kit. The secondary of The Tesla Coil is Just an Inductor connected to a
Capacitor and They resonate. That's all There Is no magic it doesn't pick up any strange Energies out of nowhere
Tesla Never tapped Into free Energy Using His coil there are millions of engineers that to use inductors and capacitors
In all sort of Shape and form and none of Them ever pick Up free energy Out of nowhere! [<---angry rambling]
Ever and That's Final!!!
Now that That's out of my System Let me show you how it Works like i said the second er Is an Inductor that Is
Placed in parallel with a Capacitor
and That
Capacitor Is made by This toroid or top Load to the environment and the bigger the top Load the bigger the capacitance and
Inductor and Capacitor
Connected Together Will oscillate if They are Charged
It's like Connecting a weight to a spring if you pull the weight down you will charge the spring if you let go the
Spring will pull Up the weight
Loses its own Energy But Stores It in the weight in the Shape of Kinetic Energy so now the weight it will start
Contracting The Spring and Loses its Kinetic energy and Stores It in the spring and then the spring Pushes the weight back down
Again so this Oscillation continues Going Until the system loses all its Energy due to Friction
Same Goes for a capacitor and Inductor Try to remember this, a
Capacitor Resists Against Change of voltage Across It but an Inductor
Resists Against Change of Current Through It so for Example if i charge the capacitor to a voltage like
VC(???) and
Connected Across an Inductor with zero Current What happens is that Initially the inductor doesn't want to change its current so it stays at zero
But as the capacitor continues pushing Energy into the inductor its current
Rises to some level as it's charging and at The same time the capacitor voltage drops all the Way to zero Because it's Losing Energy
Now we have a capacitor that Doesn't have any Energy but the inductor has
Charged To some current and wants to continue pushing It through into the capacitor so it charges The capacitor Backwards
The voltage of the capacitor Goes all The Way negative and the current of the inductor drops all the Way to zero
Again we Have a capacitor That's Charged and an Inductor that Doesn't
Have Any Current The capacitor Pushes its Energy into the inductor and the inductor Charges to some current
So this continues Going for a While until the system loses its energy to
The Resistances of The circuit and Radiation the oscillation Frequency of the circuit Is 1 over 2 pi square
Root of L Times C which is the inductance and capacitance
Values This Is also The resonance Frequency of This Circuit now
Anything in the world can store a lot of energy and its resonance You just have to excite them correctly
so if i heat this inductor and capacitor
At resonance Frequency it will build
Energy upon
Energy and the voltage field is so high that the arcs will jump out of It like you saw now how do we transfer energy
To the secondary by making a simple?
Transformer
winding a few turns of primary and then provide an AC with a frequency that matches the resonance of the secondary and that is guaranteed
to keep the excitement going
[Classic Piano Music Plays]
What do we have here? A low-Power FULL BRIDGE RECTIFIER and here's a cute little
Transformer Like a traditional Wall Adapter first They have a Transformer That Steps down 120 Volt AC into 12 volt
AC Which Has 17 Volt Peaks Then They Feed back into a
FULL BRIDGE RECTIFIER !!!!!
[EXAGGERATING TO THE MAX!@#$%!]
And a Capacitor That Generates Around 16 Volt DC Then They Feed that 16 Volt into 15 Volt And 5 Volt
regulators to power the low power circuit
[Classic Piano Music Plays]
Most Solders come with something Called the flux What it Does is that It Cleans the Surfaces to be soldered from
Oxidised Layers so the soldering can Be done much easier But then the flux creates These Fumes that I suppose not Very good for Health
There are these fans you can Buy that Sucks the films away
[Classic Piano Music Plays]
It's time to mount the power IGBT's on the Heatsink
IGBT Is a Type of Transistor That's a Mixture of fets(???) and BJT's
You don't need to worry about that though it's like a switch That opens and closes based on the input Signal
[Classic Piano Music Plays]
These Things heat Up quite a lot That's why they have to be on a Heatsink to cool down or?
IGBT switches are arranged Like This between a positive and a negative
voltage Supply and Their output Here goes to drive the primary of The Tesla Coil
They open and close one at a time and connect The voltage here high and low and create a square wave?
Now this Is an interesting
Transformer It Drives The Power Transistors
This Part Is a Bit complicated to Explain I'm just going to say if you think you may Get Brain Cancer Just Skip Forward
Here are the IGBT's They require a
Positive voltage Between gate and Ammeter to Turn on but you can see here that the Ammeter is connected to a minus
170 Volt DC and this ammeter is switching High-end as lots as F***
So you can't drive this Directly from your low-Power circuit so they are using a one-To-One
Transformer Like This with One primary and two secondaries the secondaries are isolated so they can Be at Any voltage They want
Now They provide an on-off Signal to the primary Which is repeated on the secondaries
One of The Secondaries is connected Backward so that When one of the switches is on the other
Is off otherwise if both Switches are on at The same time It Ensured the power Supply and boom okay so far so Good time
to check the low power circuit.
Okay Let's power it up, according to them or should
[BANG]
Sh**!
It's definitely Beneficial to check the Direction of Your components before powering it up, fortunately I think I have a replacement?
There it's Good Now, and this Thing wasn't wire it's an optical fiber that Goes between the interrupter and the tesla coil driver the
The interrupter generates pulses with a certain frequency that turns the output power on and off both
To generate sound and to limit the output power so that The circuit won't overheat and Blow Up
It is connected to the driver circuit with optical Fiber Which is not electrically Conductive so all the noise and
Radiations from The output won't go back to mess with the interrupter circuit and also the user won't receive a shock
Unfortunately You Know I went ahead and Got One of These fans it's only 28 Dollars from circuit specialists i
Recommend Having It It Sucks The solder Fumes away from your lungs and absorb some of It too i leave the link in the description
If you want one [Classic Piano Music Plays] and Now it's time to install the
Power Full Bridge Rectifier Now Here's another awesome usage of The full Bridge Rectifier
Originally We Have our Ground Connected here and AC comes Here and if We Measure the output there we Get Bumps like This and
If we Put a capacitor at The output we Get a rectified DC Now if we Move Our reference Ground from here to here
and Measure this point we Will get positive bumps like This
and if You measure this point You'll get negative bumps like This and if You Put capacitors Between these
Points and The reference Ground We Will have a positive
DC Supply and a negative DC Supply Here in the OneTesla design They provide 120 Volt AC
Here Which has 170 Volt peaks so we will have positive
170 Volt DC There and
Negative 170 Volt DC There of Course we don't Need these two diodes and can do the same Thing with two single Diodes but
Whatever isn't the Food rectifier Just Beautiful like i said it's not a puny single diode Rectifier
You can Get This Shirt from the link Below as a Tribute to our hero the full bridge rectifier
[Right Hand Rule Music Plays]
This is interesting The Primary winding of The Tesla Coil is made of thick white copper on both?
Sides of The pcB itself i think it's Seven Turns if I'm not wrong This giant capacitor is not
Directional and it's Placed in Series with the primary of the Tesla Coil now this is interesting We Already Know that we can have a
square wave of Plus/Minus
170 Volts across the Primary of The Tesla Coil but Why stop there when we can add a
Capacitor Right Here Which with the inductor will have its own resonance Frequency if the frequency of these square Wave Matches That
Resonance Here we Will Have voltages in orders of Thousands of Volts Which will translate into millions of volts!
On the output of The Tesla coil, but the secondary of The Tesla coil already has its own resonance
Frequency so the Primary L and C must be Designed Carefully, to provide the same resonance Frequency as the secondary
[Classic Piano Music Plays]
This Thing Is a Current Transformer
The Currents That Runs Through The Primary of The Tesla coil is sensed by This current sensor
Transformer in OneTesla
Circuit We are Sampling The
Current Of The Tesla Coils primary and Feed it back to the circuit to make It oscillate Which oscillates at the same Resonant
Frequency Of The Primary This circuit Doesn't have a Feedback from Secondary unlike circuits such as
Slayer Exciter so Similar to the traditional
Arc Tesla Coils The Designer of Such Circuit has to make sure that the primary resonance
Frequency Exactly Matches The Secondary resonance Frequency but This also means if the environment Around The tesla coil changes
It Changes The capacitance of The top node Changes The resonance Frequency and so the output power Say Like This.
[TASER NOISE]
[Classic Piano Music Plays]
Have to apply a Few coats of Varnish to the secondary?
[Classic Piano Music Plays]
We have Huge Arcs Jumping from the top Load Which i'm guessing are around Half a Million Volt if not higher and
This Power is Around Twenty centimeters Which means we Have
25 kV across Every centimeter of This Tower That voltage is high enough to easily Break Through the wire
Coating and Arc To itself Like I've Seen in my old Tesla coil
[Worst Frame Shaking]
:P :V
This is Why we covered The Secondary in a Thick Layer of Varnish to prevent unwanted arcing and
Also This is Why we wind the secondary in a single continuous Layer from top to bottom
Because otherwise If You Overlap The Wires We are placing
Huge Voltages Side By Side That Will Arc Through and Burn the winding and This is most of The things you Need to know about
Tesla Coil
