HANDMADE LISTENING MINI DEVICE How to make with your own hands at home

In today's video, I will show you a wonderful idea of how to make listening device with your own hands at home. DIY Small FM transmitter Very easy and to do this we need only a few electronic components. Closer than 5 m, the transmitter is very phonetic. An ideal distance is 10 m. In order to achieve better quality Experiment with microphones A lot depends on them. And also on the inductor. Also, the frequency of the FM receiver settings range may depend on it. Hey, guys. Many people in the comments of past videos asked me to show something interesting from the field of electronics. of course, I will comply with your request. In today's video, I will show you a great idea of how to make a simple FM transmitter with your own hands. With this transmitter, for example, you can listen to conversations in the next room. Just pre-install it in the next room, go to a radius of no more than 15 meters, because it will catch somewhere 5-15 meters. And using a conventional radio, find a suitable wave that will be picked up by the FM transmitter, and listen. The idea is very cool, it's simple. Just a few components, so you can make it all literally on your knee. So stay with us and let's do it soon. The pad contains all the components we need, except the power supply. One ceramic capacitor for one nanofarad, also a ceramic capacitor for 47 picofarad and another for 6.8 picofarad. One microphone, the simplest inductor for 5-6 turns, a transistor 2-n 2222a, two resistors: one for 100 ohms and the second for 4.7 k. Well, we also need connecting wires, one of which will be used as an antenna. Well, we will need power from 3.7 to 5 volts. In order not to confuse you with long conversations and beam soldering, since this is all going to be soldered literally on the knee, without using boards, I'd better draw a chain first. Microphone... the minus of power supply... 102th ceramic capacitor... a 4.7 kilohm resistor... a 100 Ohm resistor...ceramic capacitor for 6.8 picofarad.... transistor 2n 2222a...ceramic capacitor for 47 picofarad.... inductor... antenna…. plus the power source. The chain is there, the components are there, so I start soldering. I hope you don't need my comments here. So, the chain is already assembled. We just need to solder the antenna and connect the power source. This is a plus, and this is a minus. For testing, I will use a 5-volt power supply from a mobile phone. Later, you can put it all in a matchbox and use 2032 battery power. Turn on the power supply in the socket, turn on the radio and look for a wave. To make it easier to find the appropriate range, periodically tap on the microphone while searching. So the transmitter is in the other corner of the room. Now I'm going to try to turn up the volume and say something. wow, guys, that sounds really cool . I walk around the room left and right, from one corner to another corner now. And there is this distortion. I don't know if the distortion is due to me going back and forth, or the distortion is due to the radio being set too loud. And plus, the radio is close to the transmitter. In principle, I am very happy with the result, given that there are just a couple of components and everything is done on the knee. So if you liked this video, be sure to like it and also in the comments do not forget to write what you would like me to show you my next videos. Well, that's it for today. Thank you all very much for your attention, have a good day, bye bye. Welcome to the channel Roman Ursu Hack.
