Most of people ask TV transmitters. So Today I`m going to give you a very useful circuit diagram. By using this circuit you can send your signals 75m to 100m. This circuit diagram is not my own circuit one of my friends gave me this. I suppose you guys also....

The TV transmitter circuit given here uses UK standard 1 FM modulation for sound and PAL for video modulation. The audio signal to be modulated is pre-amplified using the transistor Q1 and associated components. The transistor Q2 has two jobs: production of....

Notes: The frequency of the transmitter lies within VHF and VLF range on the TV channel, however this circuit has not been tested at UHF frequencies. The modulated sound signal contains 5. 5 -6MHz by tuning C5. Sound modulation is FM and is compatible with....

A very simple and high quality TV transmitter circuit based on IC MC374 is shown in this article. MC1374 is an integrated TV modulator circuit that can be used in various TV transmitter applications. The MC1374 includes all necessary circuitries required for....

This is design circuit for UHF transmitter circuit. The TV transmitter circuit is working on the UHF channel, 470-580 MHz frequency channel 21-34. This transmitter can radiate as far as 30-100 meters by using a cable 10-20 cm. This is the figure of the....

This small video transmitter is very usefull for video surveillance on short distances ( up to 100m ) equipped with a black and white or infrared camera mo...

The T5753 is a PLL transmitter IC which has been developed for the demands of RF low-cost transmission systems at data rates up to 32 kBaud. The transmitting frequency range is 310 MHz to 350 MHz. It CAN be used in both FSK and ASK systems. By ATMEL....

Simple TV transmitter circuit using the TV modulator circuit IC MC1374. 12V supply, channel 3 or 4 operation, FM modulation for sound....

A very simple TV audio video transmitter circuit can be designed using this schematic diagram. This TV audio video transmitter circuit can be used to transmit video signals from VCR ( or some other device ) to a TV without using any cable. Video signals....

Here is a handy gadget for test- ing of infrared (IR) based re- mote control transmitters used for TVs and VCRs etc. The IR signals from a remote control transmitter are sensed by the IR sensor module in the tester and its output at pin 2 goes low. This in....

The circuit presented here is a simple audio/video transmitter with a range of 3 to 5 metres. The A/V signal source for the circuit may be a VCR, a satellite receiver or a video game etc. A mixer which also operates as an oscillator at VHF (H) channel 5 TV....

A 'TV modulator' is really no more than a transmitter. It is a very small transmitter, admittedly, but none the less that is what it is. What does a modulator actually do? In general -and this design is no exception to the rule - it is a simple oscillator....

Using this low-cost project one can reproduce audio from TV without disturbing others. It does not use any wire connection between TV and headphones. In place of a pair of wires, it uses invisible infrared light to transmit audio signals from TV to....

Using this low cost Project one can reproduce AUDIO from TV without disturbing anyone. It does not use any wire between TV and HEADPHONE. In place of pair of wires it uses invisible Infrared light to transmit audio signals from TV to Headphone. Without using....

I have seen these devices advertised in magazines, they sell for around £40-£50 and use radio to transmit between receiver and transmitter. This version costs under £5 to make and uses a cable connection between receiver and transmitter. For example, if you....

This is the circuit of a 500 watt linear amplifier, based upon a design by Frits Geerligs, PA0FRI, who has his own homepage at http://home.planet.nl/~fhvgeerligs. The circuit uses four PL519 TV line output valves in a very simple circuit that will deliver....

This is an IR transmitting circuit which can be used in many projects (I designed this to try to make my 3D glasses wireless). This IR transmitter sends 40 kHz (frequency can be adjusted using R2) carrier under computer control (computer can turn the IR....

Using this low cost Project one can reproduce AUDIO from TV without disturbing anyone. It does not use any wire between TV and HEADPHONE. In place of pair of wires it uses invisible Infrared light to transmit audio signals from TV to Headphone. Without using....

The ATV exciter described here uses a pair of Hamtronics model TA451 2-watt narrow-band FM voice transmitters to develop video and audio carriers on 439.250 MHz and 443.750 MHz. The TA451 is a single board, phase modulated exciter designed for amateur radio....

This is the circuit of a 500 watt linear amplifier, based upon a design by Frits Geerligs, PA0FRI. The circuit uses four PL519 TV line output valves in a very simple circuit that will deliver over 450 watts at 3.5 MHz (350 watts at 30 MHz). PL519 (40KG6A) is....

In this fast-paced world, there is little time for inconveniences and a greater need for portability and adaptability. The idea for an Audio/Video transmitter stems from this need. There may have been times when you`ve wanted to hook up your VCR from one....
