Big Rock 3s FPV DJI O3 + Bitrate OSD
268
Published 2024-03-04
V2's are using TrueRC patches and stubbies. O3 is using a FlyFish RC long antenna made for the O3.
Went about expected for this area. I get horrible analog signal out there. I'm parked with my back against a building which is not ideal and don't have LOS most of the time but that's about typical for anywhere that isn't a big open space. There honestly isn't a whole lot I can do in an area like this and the average reasonable range stays around 250-300 meters. In this case going behind me a little under 200 meters causes me to lose video for a second around the building I have my back against. I probably wouldn't have lost video if my receiver wasn't so close to the building. While I could park just right in a different type of location and have way better range, this is about what I can expect just being in some random location that isn't in the middle of nowhere. It's also of course better when I'm not sitting inside the car.
If you study enough videos of O3 footage showing the bitrate then you can sort of get an idea what to expect given certain layouts and obstructions. You can see that even on the ground you don't really start to lose signal at the first loss of LOS like you might with analog. Small objects like bushes or trees or even walls don't really drop the signal until enough of them stack up. When it comes to the patches, if let's say at any given time I'm driving to my right or left, I can turn my head and expect to see somewhere between a 5-10Mbps increase on average. Another thing you can notice is that a lot of times the signal is not the same heading away vs heading back toward me. Even with the antenna not being directly blocked by anything on the truck that will happen, so increasing the height and giving it even more head room would probably fix that.
It's a pain that takes forever to render videos with the subtitles file included when using the V2 goggles so I doubt I'll do that again. It basically had to create over 7000 segments, 1 for every frame. Starts gorilla pounding my CPU like it fumbled the banana heist.

With this you made my day! Nice and stable video quality, love the idea with the adjustable mirror, exploring the area and reveal the true speed bit by bit. A total pleasure to watch π Dreaming of an unlimited range FPV RC car of my own...

For anyone else looking the cyclist following starts at 7:35

Super cool brother !! Looks like that battery voltage was swinging a lot from 7.5 to 9 wich seems a bit strange , that cyclist felt followed heheh , looks like you have a much better range now or maybe is just cause of this new area looks bigger
-
Nice run! How much did you pay that cyclist for his appearance? ;)

hey, I tried putting together one of your tl494 based interrupters, believe it was apart of a push pull coil you built, the frequency range on the POT seems to be perfect, with full range of control but for the duty cycle it seems to only want to work from the left side to about the middle of the potentiometer then the rest of the way is maxed out, why is this? and how could i use my full pot range for the duty cycle? thanks!

Ahoy fellow hi voltage friend i have a sstc driver from eastern voltage research & i get little to no output..the 555 & ucc gate driver chips work & ive triple checked my solder points removed the igbts & test good maybe i could have you look at it???
