Built the Tesla coil.

You've got a coil.

Giant serpent, curl and coil!

And it's not a tesla coil.

If you put a coil around it,

So in this picture, you see that rotor four is spinning faster and rotor two is spinning slower.

When we have shuffled off this mortal coil...

When a coil is moved near to a wire with current flowing in it current flows in the coil as well.

JULlET Here's such a coil! come, what says Romeo?

What I need to do is wind a coil.

This is the rough idea behind rotor encryption machines.

Whenever current flows through the coil, this becomes an electromagnet.

First, we choose from 1 of 6 possible rotor orderings.

Then we select an initial position from the rotor sequence.

And there's a rotor there that this motor is spinning.

And if you manipulate the speed of this rotor, you are actually able to crack the rotor and eventually even have the centrifuge explode.

And the other way around, if you increase the speed of rotor three and decrease the speed of rotor one, then the robot pitches forward.

This destroyed the uniform distribution of the initial rotor position, and after repeated observations, it allowed the allies to reverse engineer the rotor wirings completely.

Understand that each rotor position is equivalent to a location in the sequence.

When the rotor advanced, an entirely new path was defined for each letter.

Because I want to get my coil to have about 4 ohms of resistance.

So we were able to associate the small digital warhead with the rotor control.

Each rotor wheel had electrical contacts on either side with a maze of wirings within.

The rotor is that moving part within the centrifuge, that black object that you see.

And I'm going to center that coil right over those magnets so it's just above it.

That coil is connected to an R.F. amplifier that creates a high frequency oscillating magnetic field.

Now, the state of the art technology of the time was called a rotor encryption machine.

In the canal, which is just outside the restaurant, there is hundreds of meters of coil piping.

Imagine a coil. For those of you that are engineers, there's a capacitor attached to it too.

They're going to survive as long as our species survives on what Shakespeare called this mortal coil.

You coil it around so that you get 1s and 2s and 3s on the outside, like

So at each rotor position, there's an electrical path from every input letter to every output letter.

And what I'm going to do is take this wire and wind an entire voice coil from it.

It was an electromechanical rotor machine invented by a German engineer at the end of the World War I.

This is a 100,000 volt Tesla coil that I built in my bedroom, much to the dismay of my mother.

You wish to make sure that a helicopter can be recognized, no matter what angle it's rotor blades currently have.

The four things that I need to make my own speaker is a diaphragm, a coil, a support, and a magnet.

The security of rotor machines depends on both the size of this key space, and the randomness of the key setting.

If the operators had instead rolled dice to decide their initial rotor positions, the starting points in the sequence could have been uniformly distributed.

like a generator, as our system is dynamic, dynamic magnetic fields, in cutting the atoms of the copper winding of the coil, it creates energy.
