Simple Walkie Talkie Circuit
In this article I have explained a simple walkie talkie circuit that can be easily built by any hobbyist and used for communicating between rooms or floors or simply for having some fun across neighbors and friends. The range of this system is around 30 meters. A walkie-talkie, also commonly referred to as handheld transceiver is […]
Simple FM Radio Circuit Using a Single Transistor
When it comes to making an FM receiver it’s always thought to be a complex design, however the one transistor simple FM receiver circuit explained here simply shows that it isn’t the case after all. Here a single transistor acts as a receiver, demodulator, amplifier to constitute a wonderful tiny FM radio. It’s basically based […]
Transmitter Receiver Circuit for 80-meter Ham Radio
This tiny and simple transmitter, receiver set will allow you to communicate over 100 of miles across the world, by tuning to 80-meter amateur ham radio stations. What is 80-meter Band The 80-meter uses 3.5 MHz frequency band for radio communications, which gets the permissions under amateur radio use Between 3.5 to 4.0 MHz in […]
Mini Transceiver Circuit
A transceiver is a wireless communication device which has its own transmitter and receiver units built-in for communicating with another similar device at some distant location. The user on both sides with the unit has to switch from transmitter to receiver and vice versa while speaking and hearing to each others conversation respectively. Introduction In […]
