Stable radio bug

A radio bug is a simple radio transmitter with a microphone that picks up the smallest sounds around you and transmits them through a radio wave. Thus, leaving such a device in a suitable place, you can listen to everything that is done around it.

DIY do-it-yourself simple radio bug

On the Internet, you can find a huge number of schemes radio bugs. Some circuits are too complex and require tuning, others include scarce radio components, and others do not work at all! I bring to your attention a bug scheme,

Simple audio transmitter

This transmitter showed good quality of the transmitted music, so I recommend starting with this scheme. As practice has shown, an assembled generator on one transistor cannot, stand in one place, without an additional cascade, constantly

Stable beetle at 100 meters

The article presents the design of a radio transmitting device with a range of up to 100 meters. Such a radio bug was built according to the three-point capacitive scheme (like all other known schemes), the components were carefully selected. Frequency doesn't swim like

Stereo FM transmitter from MP3 player

I don’t have a car, but I decided to use this thing in my own way. Like a stereo transmitter. Why do I need it? And in order to broadcast sound from the laptop to the music center. The fact is that I like to watch a movie on the big screen, on

Flexible radio beetle

Recently, an old mobile phone inoperative fell into my hands. As a result, it was disassembled for parts. A train of an interesting form with smd components did not slip out of sight. As a result, without thinking twice, I decided to make a radio bug on a flexible board. For beetle

Silencer for the frequency of television and radio signals

I present to your court the design of a frequency silencer. A fairly simple and 100% working circuit is designed to suppress television and radio signals. The device will be able to jam almost any TV channel (except the satellite of course) at a distance of up to 15

Simple radio bug

The design of such a radio bug is quite simple, practically does not need adjustment, and in the presence of all parts can be assembled in half an hour. This is a great option for a beginner who is just starting to learn and assemble simple radio circuits. In spite of

400 meter radio bug

Today on the Internet you can find many schemes of radio transmitters. For many months, almost half of them were repeated, but not a single circuit showed the required parameters. Long-range schemes met, but stability left much to be desired

Radio microphone - radio bug

This is perhaps the most popular simple and common radio bug or radio microphone circuit. A minimum of detail and a minimum of time is required to build this baby. Through the use of a microphone from Chinese products, the sensitivity of this

Miniature Exam Devices

I think many remember Leonid Gaidai’s famous film “Operation Y and Shurik’s other adventures,” how they passed exams on the synchrophasotron.This is precisely what this miniature device collection for examinations will be about. And start

Radio bug

I propose a simple radio microphone circuit with a range of up to 30 meters. The signal can be received on the radio (cell phone, player or on a regular, etc.) If everything is assembled correctly works without settings.
