Interesting link about magnetometer fluid.

Добрый день не подскажите какие флюз биты при прошивке используются ?

fluze Bits there is ?

Fuse Bits ?

I found this project interesting, so I decided to do it. It's not easy because, as I mentioned, there's no component layout, which is a bit tricky with SMD. I tried to create my own board layout, but I'm still missing a few components. I'm leaving out the resonant capacitors and the 220uF electrolytic capacitors. Can someone help?

Gerber files does not contain element descriptions or outlines. The lay6 file contains element outlines, but it's unclear which element it is, for example, R5 or R8. There are no letter symbols. Do you have a drawing or file that would solve this problem?

Thank You Fisher

An old patent for a similar sensor

Nice project! Thanks for posting.

What proton-rich liquid did you find best for your sensor?

I use purified kerosene.

The sensor's inductance, together with capacitors C22, C28, C34, C35, C36, and C37, forms an oscillatory circuit. This circuit is tuned to the following frequency ranges:
Range 6 - C37 - 3320Hz
Range 5 - C34 - 2869Hz
Range 4 - C36 - 2463Hz
Range 3 - C35 - 2111Hz
Range 2 - C28 - 1800Hz
Range 1 - C22 - 1511Hz

What type of capacitors did you use? What type of dielectric? Relay R2-Nil-1C-12. Could you suggest an analogous type? I can't find one. Could you attach a picture of the board so we can see the component layout or do you have a file with the component layout on the board? I'm planning to build this magnetometer, so I have some questions.

Thank you very much. Could you describe your experience with this magnetometer? What are the typical detection ranges? For example, a shovel, a car?

The magnetometer detects a magnetic anomaly from a passenger car at a distance of 8-12 meters. This range depends on the vehicle's position relative to the Earth's magnetic field and the magnetometer's relative position. A T-34 tank is detected at a distance of approximately 20 meters. A DP-27 machine gun is detected at a distance of approximately 6 meters.

The photo from inside the magnetometer shows a NEO-M8N GPS module, and the parts list shows a Beitian BE-800. Which module should I use?

You can use both the first and second. Both work. $GNRMC and $GNGGA, UART baud rate = 9600 - required parameters.
