- At last I got around to free the car from its dusty dungeon in the basement and took it upstairs to my workbench. I have relocated the cam to the roof and added a plastic roll bar for its protection. Also, I have equiped the VRX with helical antennas, hoping to boost range a little with their higher gain.
I went for a test ride last Sunday, after I had searched for and found a good area with the help of Google Maps. Unfortunately it rained the day before and everything was quite muddy, but it was a succesful test nevertheless.
I've reached a distance of around 900 meters and might have been able to push it a little farther, but didn't want to risk losing the video feed. I might try next time, though...
Again, the video is what was recorded with the receiver, so it's what I saw while driving. I have added the OSD so you are informed about the most important data like distance, bitrate etc.
Thanks for watching! - Наука та технологія
Nice build and great explanation, brother! Subscribed 🤙
Thank you! Some of your videos were a great help with putting the car together.
Very nice 👏Good Job 👍
Thanks! 👍
niceeeee
Thanks!
hi once the far away how to see the car location, any possibility bro
Hi, I guess the easiest way would be to use a cheap flight controller with GPS, connect it to the VTX and use it to show the GPS location on the OSD (canvas mode). More elegant would be to use some kind of microcontroller (Arduino, Raspberry) with attached GPS and program it to provide the data to the VTX. The most convenient way would be to use some kind of standalone GPS that can provide the data to the VTX in the correct format, but I'm not aware of the existence of such a product.
Hmm wonder why nobody uses a cellphone data connection to stream the FPV video. Then the range would be unlimited. Even more so when Starlink to cellphone reaches prime time, and it is in testing.
There is already such a system on the market, it's called CloudRC if I remember correctly. I think the biggest problem with such solution is/will be latency. Everything above ca. 150ms will become a problem, especially when performing faster maneuvers like with a quadcopter. But yeah, I'm sure the future will bring us some interesting cellphone network based FPV solutions!
Next challenge go to 1Km range
That's right! Just have to find the right spot on the map to try it. With all those hills and forest here it's not easy, need a wide open space or something like that.
