How to make a video transmitter and receiver? Answered

I need a small compact and light video transmitter and a powerful receiver that I can use for my Drone, but i don’t want to empty my wallet. Is it possible to build a simple one, that sends video and audio via(with)/without – internet, I wanna try both, but not very complicated?

Thank You.

Video and audio channels are not all that easy to transmit when you are confined by space and weight. That is a lot of data to be sent when you have a small battery, lightweight craft, and possibly long distances. Having said that, Amazon has a small camera that you could use for about $50. You may have to do some modifications to fit it to your drone, but it should work.

Best of luck!

There are many 802.11 wlan based links that are popular and typically a bit cheaper than analog setups. However due to the overhead of all the technology behind the digital link, there is a considerable amount of latency (possibly as bad as 500mS) and dropouts can occur. There may be more obscure ways to 'make' a device transmit video in such a way... Possibly a raspberry pi zero + 1080p camera module? Whip up some code on android to allow video streaming over a adhoc wifi connection? It will not be very long range...

5.8G analog transmitters/receivers appear to be cheaper now than ever, I see some on amazon as low as $40. Lower frequencies are also typically better. 900MHz ISM band is generally sought-after, although you might need a licence to use it.

Another idea would be to use a UHF RF modulator with an RF amplifier and an old analog TV w/ an RF input. I have not found a cheap RF amp, however. Also the frequency is so low that you would need very long antanna's for good reception, and you would be transmitting illegally as well.
