Video transmitters

This is a “battery-powered Transistor FM Tracking Transmitter” that communicates a rehashing radio signal which can be recognized

This small circuit transmitter processes the signs of audio of a sound table or microphone, and the signs of video of a camera, or still the audio signs and video of a DVD

This is simple FM Wireless Microphone circuit diagram. We can use it to send all sound to the FM receiver. In this circuit has RF amplifier. So this circuit have two resonance circuits and also two trimmers. This cause have Higher efficiency and transmission far up.

This is an interesting DIY circuit tutorial, where we are going to demonstrate an FM stereo transmitter in detail.

In frequency modulation, the data is transferred by varying the frequency of carrier waves. Also, there are different ways to make

FPV cameras are small, lightweight and cheap, and are mounted onto your aircraft to send real time video back down to you via a video transmitter. In this guide I will discuss all the things you need to care about w…

This is a 1 Watt PLL FM broadcast transmitter. The RF output varies from 500mW to about 1.2W depending on the frequency selected and RF output transistor used. Motorola 2N4427 always seems to work well. Transmitter uses CMOS PLL VCO that prevents the frequency drifts. The frequency is selected via DIP switches. The transmitter is supplied by 12V DC and can also be powered from the battery.
