Ivconic Magnetometer/Gradiometer

[ivconic]

We worked with a Chinese colleague for a couple of months on improving the FGM-3 sensor and now it is a completely new and much better quality sensor. A new version of the sensor with many qualitative improvements is also being prepared. But the price of that sensor will be higher.

We are slowly completing the offer!
Now here is the sensor.
This is the basic sensor model, an improved version of the original FGM-3 sensor.
The price is for 2 sensors in a set.

I think the Chinese and I discovered what the problem is with shopping in some countries. It was a ridiculously small amount to collect part of the postage.
That's why, from today, shipping and postage are free, that is, on the seller's account.
This will have a very small, insignificant effect on the price of the item. But it will solve the problem of buying in many states.

We are working on some changes and additions to the ad.
In a few days, all ads will be active again.
The language barrier is a big problem and I don't fully understand my Chinese friend, but I understood that there are some minor problems when filling out the ad and that in a few days everything will be fine.
He is currently working on some certificates and branding.
That's why he has to re-create some ads.
At the same time, we are preparing several more interesting offers on Aliexpress, soon.

HI MR IVCONIC

WHAT TYPE OF TUBE IS IT USED TO PUT FG3 SENSOR IN IT

THANK YOU SO MUCH

[ivconic]

Mostly plastic. I try to find strong plastic tubes that don't bend.
On a couple of occasions I have experimented with non-magnetic steel tubes (they are hard to find, I came across a few pieces by accident) and on a couple of occasions with pure copper tubes.
A tube of pure copper (I emphasize this "pure" because often various alloys are sold as "copper") has proven to be the best for this purpose, except for the problem of the weight of such a tube.
Pure copper acts as a "filter" and the sensors work more uniformly and quietly. I discovered this by accident, experimenting.
In the pictures below you can see all 3 cases; non-magnetic steel, plastic and copper. (click to enlarge)

Very rigib carbon fiber tube! https://www.amazon.com/Carbon-Fiber-...de=11260292011

Despite my health problems, for the last few months I have been working intensively on a completely new device that I could also classify as a "magnetometer/gradiometer".
At first it seemed to me that I would have an easy job. However, I was wrong.
A big and serious job has opened up, which I am now slowly bringing to an end these weeks.
The device in question is placed in an ordinary "tube", which will have only one "soft" button for "ON/OFF" and nothing more. Everything else happens in the Android app.
There is two-way BT communication.
The device will have two versions, a version that will work with sensors that have a frequency output and devices that have a voltage output.
The use of existing FGM-3 sensors is possible. For the version that outputs voltage; I specially designed a small accessory, a converter that will be added to the FGM-3 sensor and convert frequency into voltage, very linear, stable and with excellent resolution.
And in my plans until autumn, I also have the production of a special "FGM" sensor that will have both frequency and voltage at the output.
I must mention that the previous cooperation with my colleague from China has been DISCONTINUED and is no longer ongoing. Reasons are subjective in nature and irrelevant to the topic.
My colleague from China will work for himself from now on. Whether they will still offer sensors or not, I don't know or care.
So from this moment on I do not stand behind his products on Aliexpress and have nothing to do with it anymore.
As for the new device, I had to write almost the entire code from scratch. I added many improvements to the code, more accuracy, more linearity, more options, etc.
The previous experiences with the sale of "Euromag3D" are surprisingly very positive, most customers contact me regularly, I collect their experiences and it turned out to be a very good story in the end.
I must mention here that this is the case only with the devices and kits that I have personally built and sold so far.
I am not implying here anything that came from my former co-worker from China, who persistently did not listen to me and made many disastrous mistakes that have caused me great harm so far.
But there is something good in everything bad. I learned something new and very valuable from that cooperation. That I have to be much more cruel to people and that I never trust people. And of course, that I always charge for my work in advance.
For now, here's a short video testing the beta version of the Android app:

And now a little joke for the end...
Previous experiences with "project sales" (dating from 2019) brought me a very valuable experience in understanding things.
I have had several thousand contacts and correspondence with various people around the world, since 2018, when I first presented my "Euromag3D" in public.
And on the topic of selling the entire project. Ha, ha, ha!
So I'm going to joke here now and say that this new project of mine is also for sale as a complete project.
My "book" of jokes and taunts is not finished yet, there are plenty of blank pages to fill!
Notice is given; only serious enterprising people (with lots of money) can contact me about my new project.
All the others who have torn underpants, are barefoot and with black under their fingernails... please do not contact me, I beg you from the bottom of my heart! Spare me!
