    I wasn't in a position to see something that ordinary people couldn't. Except maybe a couple of times, and even then it was about not so "secret" things.
    I will always remember something I saw in the late nineties.
    Before that, a pre-context is needed.
    In Belgrade, the capital of my country, there was a gathering, a meeting, the police of my country and the police of the state of Israel.
    The friendship between the two peoples is traditional, so the cooperation of state institutions is close.
    At that meeting, there was an exchange of gifts between colleagues.
    And our deputy minister, (police general), received a "device" as a gift from a colleague from Israel.
    He later gave it to his friend. And that friend is also my friend.
    Two small black boxes. One is the size of a matchbox and the other is a little bigger. One is the "transmitter" and the other is the "receiver".
    "Spy bug". But what! I couldn't believe how it works! A friend and I tested it multiple times.
    I leave "TX" in the room, close the room door, go 5 meters outside and stand.
    My friend took the RX with headphones, got into the car and started driving away.
    The road cascades to the top of the mountain, so I can clearly see the lights of the car in the dark.
    He goes about 10 km from me. I can barely make out the lights in the distance in the dark.
    I say "stop" almost silently. He stops. I say "turn off the lights", he turns off, I say "turn on the lights" he turns on.
    When he came back he told me that he heard me crystal clear and clear, without noise, as if I were sitting next to him.
    It is fascinating not only the long range for such a small device, but the sensitivity and selectivity of the microphone in the TX box,
    which was closed in the room, while I stood outside the room talking quietly.
    It was the end of the nineties, when we didn't have a GSM network, mobile telephony, internet, etc.
    A decade before that I had become a radio amateur. Had a few rigs. So I was not a mere layman.
    I was no stranger to that technology. But what I saw then with that "spy bug" really fascinated me.
    Next experiment. I hide the TX under the TV in the living room.
    I get into the car and drive from home to the mountain.
    There are a lot of bends, the forest is dense and I slowly move away and reach the opposite end of the mountain. The distance is about 5 km.
    But half of the mountain visually obscures the space between me and the house. Plus there is a big height difference.
    I stop the car, turn it off. I sit and listen with headphones on.
    I hear every detail very selectively.
    I can hear the TV program, clearly my wife in the background working on something in the kitchen at the other end of the room.
    At one point, a cat passes by, I hear it very clearly.
    Incredibly! I have never experienced anything like it in my life!
    Even today, it is not clear to me how I could even imagine such a thing, let alone make it!
    A few years later, I first meet the Flir thermal imaging camera, a handheld, small, police camera. It was an exclusive then. Today it is no longer news.
    I don't need to describe the delight with that camera, there are already numerous videos on Youtube.
    In both cases, it is a technology that has already reached me, an ordinary person, who has no privilege to see something that others cannot see.
    Although I had the privilege of being among the first to see such a thing.
    And then let's imagine what else exists that is "hot" today and that is very much hidden from the public.
    Of course, let's not get too carried away, this can be a double-edged sword.
    Political propaganda can abuse these facts and pretend that it has in its possession some very advanced technology...
    which actually does not exist or such a thing does not exist yet or is even impossible to exist and will never exist.
    It is clear that the most advanced technology is still hidden from the public and is primarily used for military purposes.
    And when one day it becomes "obsolete", it slowly moves into the civil domain. Especially if it can be mass commercialized.
    When Flir met all the military and police needs of the home state; it became clear that they would be without jobs and markets.
    But then some better technology appeared (high resolution satellite tracking for example) and then Flir was "allowed" to offer its products to the civilian domain.
    That's just one example. It's a similar story with drones. And with many other products.
    But one should not get carried away and believe in things that are far from reality.
    Yes, it is true that there is "secret" advanced technology, no, some things are still not possible or not yet achievable.
    With stories like this, I always wonder just one thing; can all that fantastic knowledge and progress be used to directly help people with various diseases?
    In treatment? Are there already drugs for "incurable" diseases? Various conspiracy theorists claim that yes.
    I have no proof and I can't possibly know that.
    But the sad human history of stupidity gives me the right to believe that there have long been drugs and methods of healing for many serious diseases that are still killing countless people on the planet.
    It is obvious that still not enough people are dying on the planet, fast enough, so we have the situation we have in the world today.
    All the progress of technology that we are witnessing... is not worth a penny... until it is 100% in the service of people on the planet, every "small" and "ordinary" person under heaven's cap.
    As long as it is only the privilege of the minority; it has no real historical value.
    And it will not help humanity and the planet itself in any way.
    Thus; it's not worth anything at all.
    And it doesn't deserve for us, the smart people here, to deal with it.
    To spend our limited and very valuable time on those stories.
    Detectors are a much nicer and more rewarding topic.
    Because they brighten up our gloomy lives.

      I have always preferred to take parts from electronic scraps! no matter how much they are used, they have always been more reliable than new ones!!

        The era of the flourishing of quality technology and components, as I recall, began somewhere in the late 70s and early 80s.
        There was no mass production from the East then, the first home computers, the first home VCR, the first serious HIFI systems appeared...
        the quality of those components was such that the calculated duration and retention of quality was 30-40 years.
        If you open today, for example, a VCR from those times, you will find a WIMA polypropylene non-polarized capacitor in it,
        which has retained its good characteristics and is still usable today.
        The world was not "corrupted" as it is today.
        There was no "planned obsolescence", the race for money existed, but it was not as unscrupulous as it is today.
        At that time, almost all analog circuits were in the "military" standard quality.
        It was a real revelation for me when I found some large pcbs from some medical equipment in a local junkyard about 15 years ago, and on them was the LF347 in a ceramic package!
        I collected about 20 pieces from those pcbs.
        During that period, I intensively made SMW detectors.
        When I replaced the TL084 with that LF347; detector performance jumped over 30-40% !!!
        I couldn't believe what I was seeing!
        Nowadays, it is difficult to find such quality in modern products.
        The mass use of cheap processors has also brought the phenomenon of "planned obsolescence".
        Everyone is silent about it, of course. But it is an open secret that today it is an integral part of "business".
        I wouldn't overly criticize, but in the EU, French car manufacturers were the first to start with it.
        Renault is the most notorious in this regard.
        A Renault car will serve you well ONLY until the warranty period expires!
        And then an avalanche of problems and malfunctions begins.
        Very quickly, others also accepted this practice, and in the last 20 years, even the big Mercedes.
        As a rule, car classes for the "broad masses" are made so that they do not last longer than the warranty.
        Because production needs to be maintained, work needs to be done and employees need to be kept.
        Social peace should be preserved in our own countries. You need to maintain your own economy.
        The average EU citizen feels this, he doesn't know the details, but he feels it.
        And he has the discipline of replacing the car a couple of months before the warranty expires.
        What happens next to those used cars?
        They are exported for favorable prices to "third world" countries.
        Piles of waste leave such a country and such a country remains "clean".
        And that system works flawlessly at first glance. But not for long.
        Because it is based on the almost free exploitation of raw materials from those same "third world" countries, as well as very cheap labor.
        Such an unfair system does not last long and returns like a boomerang to those who adopted it as a practice.
        Today, there are no more free raw materials, no more cheap Russian energy, and what is happening?
        Car production has stagnated and today buyers in the EU wait from several months to several years for their new car.
        The prices are much higher and the quality is getting worse.
        The same is happening with the electronics industry.
        This world was not created on lies and fraud but on honest work and a lot of sweat and blood of past generations. And as such, it cannot survive otherwise.
        Justice comes after all and takes its toll on all those who have gone astray.
        Because the planet and nature are based on truth and correctness. Anyone who tries otherwise; it can't last long.
