We’re moving forward the OpenHD project to h265 encoding/decoding with the Jetson Nano 2GB as an Air unit and NCB00 carrier board. The CM4 is capable of decoding h265 and with ochin will be the perfect combo for a goggles module!
@@WX4CB there is another carrier board with dimensions 85x50mm. Also we are developing a completely new AIO OpenHD board that will have similar technical specs with Jetson Mano. But until the OpenHD hardware is ready we’re continuing the development on the Jetson nano.
Yes - we've been trying to get a working config for a while now with the Ochin board but I've run into a few issues, a h/w issue and then the GPS loosing signal as soon as the Open.HD side was powered up. It's still not fully resolved - but once I eventually get to the field and fly something I'll bring you up to date on what I've been doing
Would have been useful to explain what Open.HD is and why you would use it. I have used Evos over the last 3 or 4 years (I still have 2) and on hot days ESC cooling can be an issue. I simply add a 3D printed grid which fits into the lid and problem solved.
Good point - I've added a link to my playlist of previous Open.HD stuff (including initial explanations) as a card and in the description. I like the grid idea, I may do that
interesting, i have just ordered something very similar but based on the 3B which is called the 3B mini and sports the same quad core 1.2ghz cpu and 1gb ram of the 3B but in a stripped down board layout and weighs the same as a Pi Zero! A 4b is a more powerful board but seeing as the zero manages, the 3b mini with four cores instead of the zeros one which are also faster plus double the ram of the zero should make it more than good enough and it has two data enabled USB headers vs the zeros one usb which could be used for on craft diversity but im hoping i can use one for a usb cam and use the csi for another cam and switch between them like you can on the 4B
That sounds interesting Steve - I've not come across that one on my browsing. There is talk about using h.265 compression which is where the 4 will have an advantage, but I'm not sure what this does to the picture quality/latency at the moment
@@CurryKitten in the comments you have been talking to a user called Mario FPV, go to his channel and you will find a video called introducing 3B mini running OpenHD, he is how i found out about it. I paid £25 for mine on Aliexpress, same 9g as the Zero but a quad 1.2ghz and 1gb ram. Shame they have no hdmi, they would be a candidate for a ultra small and portable ground pi on a TX mounted screen if they had that but they are perfect for the air pi!
@@gmivisualsjason3729 Yes, a Jetson nano board greatly reduces it, atm theres some new stuff going in development which is still secret but supposedly it is really quiet good with a lot of speedup with the new board, better code, and a more sophisticated encoding algorithm (h265)
Nope. There was talk of the interfaces being similar, but it needs either specific cameras for the PI's, or you can use an HDMI to CSI convertor and take HDMI from and HD camera
Great project Wayne, interested to see how this works for you. Please don't put it in that horrific wing...lol...Put it in something you know works instead...🤔😳🤨🇬🇧
What's up with that wing!? The trouble with putting this in something that already flies is that it can be harder to stick a new thing in post-build that planning around it adequately in the first place. I'm very much learning this with the Open.HD Quad build
@@CurryKitten Oh, you're doing an Open HD quad as well...?....I'd stick with just the quad. Winters coming, it will be easier as a test bed for sure than that awful wing...🤔😳🤨🇬🇧
You'll have to tell me what you have against the Falcon Evo... it sounds personal :D I flew the original Falcon wing probably more and any other and I've crashed it, exploded it into foamy shards and it's still flying. In theory Open.HD works better in fixed wing as the latency isn't as important. But I'll be doing two Open.HD builds. The Pi Zero in a quad and the CM4 in this lovely wing :-P
@@CurryKitten Well, it has a nice deep bay for the gear, so I can see the appeal. It's just that these wings never fly well IMO, but I look forward to you proving me wrong..🤔😳😀
very interesting Wayne, looking forward to the follow up. 👍
Me too! I'll be getting my head down and finishing the two Open.HD builds ASAP
Pretty interesting hardware indeed, Wayne! 😃
Looking forward to the build!!!
Stay safe there with your family! 🖖😊
Thanks MC - the tricky thing is now finding a decent weather day to fly things
nice to see some development...

nice, but the jetson nano is pretty big isnt it. the dev kit is like 10cm square

@@mariofpv that's cool. I just got some wireless dongles to play with.
Nice - Looking forward to it - having just tried to get a Pi Zero on a quad... well, it's a pain. Smaller modules FTW!
Ooooo. This looks nice!
Sounds cool
Wow interesting
Hello just checking to see if you are still working on OpenHD build and your progress

Excellent....... what's the latency of Ohd?
Should be the same as using regular Pi's - so 100-150ms
@@CurryKitten Is their any development happening to reduce that?

@@jotham123 It's actually quite exciting tech.....
Do can this board use camera digital DJI (runcam)?

you really need to turn off auto focus lol.... looks opretty interesting solution
Fixed focus is worse - I only have to move my hand 10mm and it's out of focus !
