Металлоискатель из TV пульта и Радиоприемника / Своими руками Однако!

They say that you can make a real metal detector from an old TV remote control and an old radio. https://zen.yandex.ru/media/dima/meta... Here, like, the effect of changing the tone of the sound should be observed when the radio wave from the TV remote control passes by the piece of iron. Well, what? Let's check how it actually works. As bloggers and articles write, for greater effect, you need to attach a coil of copper wire to the place of the infrared diode, then the real fun will be - a real "Pirate Metal Detector" or something similar. As befits a diligent hand of wrenches, I assembled and tested several variations of these mind-blowing schemes, but the result did not just not please me, but even surprised me - well, it does not work at all, and it cannot work! Neither large pieces of iron nor coils of different calibers could change the tone of the messages in the radio receiver. As they say in common parlance? - they say that they milk chickens! =) #DIYMetalDetector #RemoteControlMetalDetector For those who need details (I am rarely there) https://zen.yandex.ru/dima https://vk.com/id26168899 https://ok.ru/profile/570092326202/ https://www.facebook.com/profile.php?...
