How it works?

We shift the proton magnetic spin with resonant

radio frequency and receiving the spin echo, in

low energy magnetic field.

Not need cryogenic superconducting electromagnets.

ZYBO Zynq™-7000 Development board used in the

project. Like a one chip full Linux computer, this is

ideal for this original scientific measurement

unit to build. The measured spectral data stored on SD card.

We compare this with the database, which is inside

more than 700.000 molecule spectral data.

The ZYBO is compatible with Xilinx’s new high-

performance Vivado Design Suite as well as the

ISE/EDK toolset. These toolsets meld FPGA logic

design with embedded ARM software development

into an easy to use, intuitive design flow. They

can be used for designing systems of any

complexity, from a complete operating system

running multiple server applications in tandem,

down to a simple bare-metal program that

controls some LEDs. For systems that require an

operating system, Digilent provides an out-of-

the-box Linux solution specifically targeted to

run on the ZYBO, complete with documentation

describing how best to mold it to suit your

purposes. These Xilinx tools and Linux solution

are all available to use at no additional cost

with the ZYBO.

The ZYBO (Zynq Board) is a feature-rich,

ready-to-use, entry-level embedded software and

digital circuit development platform built

around the smallest member of the Xilinx Zynq-

7000 family, the Z-7010. The Z-7010 is based on

the Xilinx All Programmable System-on-Chip (AP

SoC) architecture, which tightly integrates a

dual-core ARM Cortex-A9 processor with Xilinx 7

-series Field Programmable Gate Array (FPGA)

logic. When coupled with the rich set of multimedia

and connectivity peripherals available on the

ZYBO, the Zynq Z-7010 can host a whole system

design. The on-board memories, video and audio

I/O, dual-role USB, Ethernet and SD slot

Step 1: Now We Look at the Parts!

By the time we will be finished this project,

we will look like this,

if still not, we worked well.

Step 2:

Let's take a Test-Glass

Step 3:

Let's wind according to the parameters,

this will be the Receiver Coil, with whitch we can sense the radio echo impulse

of the atoms answer of

Step 4:

Let's make the Transmitter Coil,

according to the specified parameters:

On an D:22mm, L:40mm, n:16, d:2mm Cuz wire

Step 5:

Transmitter Coil with magnets

Step 6: Polarizing Coil

coil parameters: D:220mm, n:73, d:2mm Cuz wire, R:0.3 ohm

polarisation pulse:7A, 3-5sec

Step 7: Excitation Coil

coil parameters: D:85mm, L:100mm, n:360, d:0.8mm Cuz wire, R:3.7 ohm
excitation pulse:0-7A, 3ms, 2.1Khz

This pulse must be at a resonant frequency of the nuclear spin in the ambient field!

Its depending on the ambient temperature and ambient magnetic field.

Step 8: Let's Make the Legs

Step 42: But What Is the 42?

... ...This is the last question...

Answer to the Ultimate Question of Life, the Universe, and Everything (42)

The answer is in this book:

Douglas Adams: 'Guide to The Hitchhiker's Guide to the Galaxy'

'a group of hyper-intelligent pan-dimensional beings demand to learn the Answer to the Ultimate Question of Life, The Universe, and Everything from the supercomputer, specially built for this purpose. It takes Deep Thought 7½ million years to compute and check the answer, which turns out to be 42. Deep Thought points out that the answer seems meaningless because the beings who instructed it never actually knew what the Question was.

When asked to produce The Ultimate Question, Deep Thought says that it cannot; however, it can help to design an even more powerful computer that can. This new computer will incorporate living beings into the "computational matrix" and will run for ten million years.'

And the answer is the 42

...otherwise

42Hz/uT (Hertz per microTesla) the resonant frequency of the proton of Hydrogen atom.

We measure that with this Equipment.

In our case:

the Earth magnetic force is: around 50uT, here in Central-Europe,

multiplying this with 42Hz/uT,

the outcome: 2100Hz Spin Echo voice of radio-frequency.

This we attach and this we measure...

If You have more question, ask!
