Peter and Josh build a micro FPV 5.8Ghz Camera and Video Transmitter using relatively cheap components purchased online.
This cool little project isn't anything new, tutorials and plans have been available online for years now, but we wanted to share how we put ours together. The full list of components are available below.
These DIY 5.8Ghz micro cameras/ transmitter setups allow you to add FPV to just about any sized airplane.
Josh mounted his micro camera on his FT Mini Scout. You can see it used in our Mighty Minis Episode.
Before starting, you'll want to choose a solder iron that works best for your needs.
You'll want to tin all of the connections before soldering, you can learn more about best practices on soldering in one of our other episodes linked below.
Here's the final soldering setup on our specific kit. (full list of details linked below)
Focus your camera lens to the focal length that you prefer and you're ready to glue it all together.
We decided to glue our camera to the transmitter so it's a self-contained micro camera setup.
Testing out our camera setup, we were excited to see how well it transmitted!
Josh was able to fly about 2,000 feet away and still got great reception.
These little cameras can be put on just about anything! Build one and share how you put it to use!

There are a lot of planes out there for long range FPV maybe you guys could review some of those type of planes too (Volantex Ranger EX or maybe a wing)! Thanks again for all your hard work!

Shipping cost to USA makes it a less attractive here. This still needs the wide angle lens.
Search Amazon.com ebay.com or aliexpress.com for "TX5823" (band E) and "MC900" camera
"M7 1.8mm lens" for a wide angle lens
The "MC900-V9" camera has 90 deg lens instead of 55

I think it ist a really great idea!
But here in germany you are allowed to use 25mw max with 5.8ghz.
Does anybody know a 25mw (or less) transmitter module?

Removing the SMA connector and solder the antenna directly to the board will save you 2-3g.

then it overheated and puff~
I bought another one and ran it on 5v using a 3.3v voltage regulator. Works fine since then..
Anyone have the same experience?

Transmission module 32 channels Dx.com SKU: 342286 US$24,16. Input voltage 7v-12v.
The transmission IC on the transmitter is 5V version -> GOPRO.

Need to get the weights all added up and compare it to one of the 32 channel micro 200mW transmitters on ebay. Not sure what the lower limit of the voltage input is on those since they have a voltage regulator on board... gets me to thinking.

That's a link for a micro board that has pre installed dip switches for 32 channels for A B & E frequencies. So it'll work with the boscam(RC305/806) immersion & other brands.

Also, just saw this on Hobby King's "New products" page. not as small and light as the one here but very inexpensive.

I'm just building a Hubsan X4 FPV Quad Copter with this TX and a small Cam from HK.
I wouldn't use the 3V version with a 1S Set up, the 5v works from 3,3-5v, so its perfect.
Do your TX get that damn hot as well???

you can find a 32ch 600mW module at banggood:
http://www.banggood.com/FPV-5_8G-600mw-DIY-TX-Telemetry-Module-For-Multirotor-p-957748.html
The 32 channels should provide compatibility to immersionrc and fatshark.
International shipping is for free if you don't mind to wait...

Time to find an alternate which is a shame if you already have a machine that was designed for the TX5200 and a 5V regulator.
We are looking at the 600mw 32ch versions now which might not fit well with the "micro" class machines due to the power consumption.

I'm new to building things like this - I have a syma x5c quadcopter running an 808#18 camera (ie the camera is running of the copter's power - I think it's 3.5v) - Can I also run the 3v transmitter off the copter's power as well, or should I get the 5v transmitter?

It worked fine until I spooled up my quad and then all I got is noise noise noise.
I can't find any of my old 1S lipos to try it on a different pack.
Maybe filtering will help if I keep running it off the main pack. I can try a cap on the power but I don't have a coil light enough.
I also noticed on the spec sheet for the camera that they recommend a cap on the video signal. Maybe that's just to AC couple or maybe that will help with filtering. Maybe I'll try it if I get a chance.
The quad runs on four brushed motors so I'm sure they make a ton of noise. Without a separate back and/or some filtering, it's not going to work. I have a quad that flies fine and video that is fine but not both at the same time.

5.8ghz has a wavelength of 0.052m. You can go with a 1/4 wave monopole. A 1/4 wave is 0.0130m. Typically, because electrons bounce around in a wire and don't travel exactly at C, you want the antenna to be about 10% longer so a 1/4wave antenna would be 0.01430, or 1.43cm which is 0.563in.
In others words, a thin piece of wire a bit over a 1/2 inch long.
In the picture there's some coax shielding so the antenna length is the UNshielded portion at the end.

Second question: is it possible to put a clover leaf antenna on it for better performance?
