This Camera can see Wi-Fi: Visualising Wireless Signals with the XJ9 Wi-Fi has become a cornerstone of modern connectivity, enabling wireless data transfer across homes, workplaces, and public spaces. It operates in the microwave range of the electromagnetic spectrum, typically at frequencies of 2.4 GHz or 5 GHz. While essential for internet access, these signals are invisible to the human eye because our vision is limited to the visible light spectrum, leaving… |

Simple DIY FM Receiver Circuits on the Internet - Do they Really Work? Recently, we thought of building a simple FM receiver circuit, so, like always, we started googling for possible circuits that can be used to fulfil our requirements, and as expected, we found a lot of circuits on the internet, but the question remains, how good or useful will they be when we put those circuits to the test? Because just like us, we found a lot of… |

Superheterodyne AM Receiver - Working with Block Diagram and Schematics A superheterodyne receiver uses signal mixing to convert the input radio signal into a steady intermediate frequency (IF) that can be worked with more easily than the original radio signal, which has a different frequency, depending on the broadcasting station. The IF signal is then amplified by a strip of IF amplifiers and then fed into a detector that outputs the audio… |

How to Build FM Transmitter Circuit One of the cool projects I always wanted to build is an FM transmitter with a good range. I have always been fascinated by some of the applications of the transmitter, especially when I was younger and, like everyone else, spent most of my time imagining how cool it would be to have some of the equipment and devices used in spy movies. So recently, while going over one of my… |

RF Controlled Robot In present time almost all the people are familiar with robots. Robots play a very important role in human life. Robots are a machine which reduces the human efforts in heavy works in industries, building etc. and makes life easy. In Our previous Projects we have made some robots like line follower, DTMF controlled robot, gesture controlled robot, computer controlled… |
