The healthy dose between honesty and accountability is so hard to judge. Don't ever beat yourself up you're appreciated.
i would really appreciate a 20 minute video off fardwell beating himself up. 2 minutes would also be very wel recieved.
Bardwell does a better job with journalistic integrity than almost any RUclipsr and certainly most big outlets. This is why you're one of the most beloved creators in this hobby!
He makes a lot of efforts to sell and makes money - and we all know it. He is an influencer of the mainstream “DJI”.
And he also has a great sense of humor 😁
It's actually so refreshing to see someone admitting when they are wrong, and factually correcting things and moving on. I think every hobby needs a Joshua Bardwell, and FPV community is lucky to have you. As a noob to this hobby, your content is absolutely essential to avoid tons of mistakes. /me is off building your 5" drone :)
Thanks for the updates, Joshua! 😊
Stay safe there with your family! 🖖😊
Very helpful in-depth info, the O3 is very interesting indeed! Been a while since I was serious about my fpv setup but this one's making me so curious.
Nice work of the corrections man 💪 Lots of good additional info in there too. Going to be a useful video to refer to when mine arrives. Cheers 🙏
Thank you for the clarification. Good to know more about the O3.
This is understood. Just goes to show that we're all learning about this new product together and while we might encounter some concerns, it's great to discover solutions and get best results later on
How cool is it to know that you're one of the world's most helpful people for those in the FPV hobby?
Great update video this system keeps surprising me.
Missed opportunity to say “I’m Joshua bardwell and I learned something today” 😂
Very helpful and appreciative of all the work you do. Some thoughts on hacking the unit to obtain additional channels and cautionary tale. The frequencies these units operate at is within the wireless networking range and has been limited to what appears to be non-overlapping or least interfering frequencies. Either you could be causing your neighbors to become very annoyed with you, or perhaps negatively affect your own wifi without even realizing it IMO
I'm glad I got the information I was curious about. The part about nuclear and the part about the output of Jimmy Lee will be the biggest issue. I watched the video well.
You are the best gift to FPV
After testing the 03 today, i was pleased with the goggles dvr view and also the penetration of the video signal, it was not going blocky in the trees where my vistas usually do, the image in the goggles had no jitters but the footage from the 03 air unit had jitters when using rocksteady, i read that this can because the esc's are at a similar frequency, i have 16bit esc on my aircraft so it is not possible to change this as they are not 32bit, well i think this may defeat the object less stabilized video with stabilization on! also the 03 seemed to stop my gps from finding satellites where i had no problem of getting a link with my previous vista, this maybe down to the gps module mounted above the camera and maybe The 03 camera is giving out noise where as the old camera did not affect it. I may upload a comparison video of the dvr and the 2.7k 60fps recording with the inbuilt 20gb storage so not an sd card issue. I hope these issues can be rectified, don't want to think i have wasted money and time.
Thanks. I'm the sort of guy that likes to deep dive into specs, so this is great.
You will always be the man. That will never change.
Props (no pun intended) for the updated video 😊
Ohh yeah 😃😃 My o3 is arriving tomorrow... And I am happy that I have DJI RC PRO remote to have clean feed from V2 thru HDMI ))
In winter if the goggles are too cold, they fog also from the heat of your face. I use hand warmer to warm the lenses if they are too cold and are getting foggy.
Good tip.
If you make it an hour n a half long, i'll still watch it all 🙌
@jan doodle I'm full-time FPV. I watch bardwell while I work. Seek knowledge so you wont be ignorant 👍
@@jandoodle6769 someone sounds jealous about their life choices 🤣
@jan doodle strange how ya keyboard warriors always think they know what's best for someone else. Seek knowledge instead of spreading vitriol. I love my job, quitting the rat race was the best decison i ever made.
FYI I believe that that the newest beta firmware (the one that gives you backwards compatibility with vista) for the goggles (and therefore likely the air unit) might disable the ability to use the hacks, so we might lose that as the firmware updates roll out.
Purely speculative
Don't worry, there will be new hacks
@@creationlabsinc.189 Check out mads tech, he shows that the hack doesn't increase the power as it did on earlier firmwares. I'm pretty bummed.
@@aviatoFPV Check his comment underneath the video, he says he got it working again
@@andytroy oh okay, sick news! No way they would be selling O3 in EU without any - user config way against the rules - option to increase for normal range.
Always the best🔥
There seems to be a bunch of small features that they should implement i.e clean video output option. I guess feedback is just provided via a support ticket.
Great video. The power difference between FCC and CE affects both Controller and goggles or only one of them? Which one? I’m about to buy a cinebot30 O3 in ELRS version. Tks, brother!
Building my first drone, didn't know anything abt drones a week ago but now I'm building my own, couldn't have done it without Bardwell.
Excellent video.....Thank you.
Is the O3 compatible with DJI FPV goggles V1?
Cameras mounted on stiff 36 inch long 18 ga spring wire can absob all the vibration . I always use a silicone o ring to mount it .
I think what you said about the v2 goggles not having a fan is incorrect.
I was thinking the same thing. I have a pair of V1's and V2's and both have a fan. It's hard to believe the Goggles 2 were designed without a fan.
The new goggle 2 have no fan.. v1 and v2 have a fan 👍
Hi @JoshuaBardwell
Thx for the great update
Potato / Avata same issue when switching, always needs to rebind...
Cheers
Evel-Knievel
Great video Joxhua!
I have noticed that the DJI FPV Remote Controller 2 will work with the DJI O3 Air Unit however the Expo/Gain and Button options are not selectable. This makes it very difficult if not impossible to fly with the DJI FPV Remote Controller 2 and I am forced to install my Crossfire system.
Well now I feel stupid. Ignore my post I haven't used Betaflight for a while.
I’ve mirrored my phone to the tv 📺 no cables , plan to add a tv into my trunk mounted . Or even put on a table . This works I flew outside watching my home tv .
I appreciate you bardwell cause you can man up and be honest. So when I say this it doesn't apply to strictly bardwell. All these people doing reviews are in such a hurry do drop there video for views and product link in description. I get it this is how you make your money. But ooofff I feel horrible for the people who rushed right away on stuff and then had issues. Like the avata drone. Glad I have patience but then again I'm always behind catching up. May not be such a bad thing. Again props to this man for making another video but to late for alot if there's things now that's a deal breaker
“If” DJI somehow enabled remote ID in their products, they would have to make it so they user could enable/disable it. This is because many people are using their products (goggles/air unit) in sub 250g drones for recreational purposes where RID is NOT required by the FAA.
please detail your discovery on hdmi signal out from o3 air unit / V2 goggles to a monitor or second pair of goggles : how to what other devices are needed. thank you
Love it that you corrected mistakes and added info.
Seems that the new beta killed the hack again. Won't buy it if it can't be hacked...
Just had a thought: If you update or active the Air Unit using a VPN "being" in the US shouldn't the Air Unit think to be there and switch to FCC?
Nope, the DJI app checks your carrier and stuff, you can't activate without sim card.
@@aviatoFPV Dang!
That makes no sense since activation is done on pc and doesn't require you to plug in your phone. Right?
Hey Joshua, please include the link for the USB-dongle you are using on Android devices for HDMI out with affiliate link. I am not the only one who would go for it after watching this video I believe. Cheers!
I like your video's, thanks. Please let me decide if I'm going to learn something today. I take it as condescending.
After putting the code in cli in betaflight, to use the osd the quad did not recognise my crossfire receiver no matter what uart it was on, I figured I'll try my crossfire on sbus then it recognised the receiver, so having to use crossfire on sbus.
I am waiting for the OS 4 which is supposed to be cross compatible with HDZero.
Very interesting and informative video. Thanks for the update. Question, after updating 03 au and goggles V2 following your video, do I need to do anything with the firmware on the diy side before reinstalling wtfos? Thanks 👍🤓
the one question we really want answered haha. I believe it is still not clear the best approach to this.
Does USB out work with DJI RC-PRO controller? Thank you for your video
Another important point missed. O3 system needs an armed signal to output full power. Same for upgraded vista type AU as well. This makes O3 system useless for wings without a FC.
Yall finally got me , just ordered the DJI Goggles 2 😂
Nice to meet you! I can't output video using dji fly app, my version 1.8.0! what dji fly version did you use?
I think you said the screws were M2 on the air unit. I believe they are M1.6 used to replace with longer screws to screw the air unit to frame.
Surely DJI will update the HDMI so you can have a clean feed? Makes sense for broadcast
The reason HDMI dongles don't work with DJI Fly is because the goggles and phone have to reverse the USB host and gadget roles due to the Android Accessory Protocol. Fly should work if you plug the dongle into the Goggles side, but obviously HDMI won't do anything like that.
hope Next product idea for used with the new DJI O3 Air Unit :
a little box receiver multi O3 Air Unit (for the strong immersive spectators) with :
-- max : 4 receiver internal, each receiver must pairing on one slot on box.
-- output : 4 hdmi 2.1 for individual screen.
-- 1 Gigabit Ethernet PoE for diffuse 4 stream full resolution 1080p 120fps. (network and use OBS for example, and can setting the iso, speed frame, optic ? because bidirectionnal information ?).
-- box dimension : smallest bossible.
- no screen, no other else ... for better low prices plzzz
😁😁
DJI you ROCKKKKS
Wonder why there is gps coordinates that are all 0’s at 19:17 when you show the set file from the o3 air unit.. so they planned something to give it the gps info in the future.
Good job
Great video, thanks for this. One question, at time 20:20 the explanation of the FOV does not line up with what you are showing. maybe I am mistaken, but I'd be grateful for some clarification here. What I am noticing is the FOV changes when you arm if using > 60fps. For example, if I am in 4:3, 2.7k, 120fps, when I arm, the image FOV goes down (zooms in). If I select 100fps it zooms less, and at 60fps there is no zoom, the image looks same as when not armed. The same is true if using 1080, 120fps crops most, 100fps less, then 60fps does not crop at all. Again, this only happens at the moment you arm. after you disarm, 10sec later of so and it goes back to wider FOV. Has anyone else noted this. I am running o3 firmware 01/02.00.00 (latest as of MAR 10. 2023) , on V2 googles (firmware 01.06.00.00).
On the being wrong theme… I wouldn’t be so quick with stating O3 would run on 25mW in non-FCC regions. It has automatic channel switching logic built in, so it should be eligible for 100mW max RF output in most European countries now! (not sure what regulations are in other non-FCC regions). Not saying 100mw is all you need for everything, but some people could actually live with that much better than with 25mW. Especially if you add the more efficient codec O3 is using (H.265) that provides reasonable image quality even down to 3Mbps…
0:21 I watch 5 hour podcasts, hit me with the longman 💪🏻
Should there be any noticeable differences in terms of control link when using Chimera7 Pro with O3 Air Unit + ELRS 2.4 Commando 8 VS DJI Controller 2?
Do you think this new system will be your new daily driver?
Mads has shown in latest firmware even with FCC hack you don't get full output power outside of the States. You can't go around it because DJI app checks your sim card to see where you are.
Yikes.
Hi :).
Do they records onboard in h264 or h265 when using Google V2? And at what baudrate?
Thanks in advance.
The in-goggle view shown seems to match the wide FOV not the normal. Is this what you meant?
A quick and dirty way to share the video via HDMI is screen sharing via a Chromecast dongle.
You can also use an Android TV box for an HDMI out. Runs all the apps needed, including analog apps like FPV viewer. You can also plug up an OTG analog receiver right to the box.
This may work for casual viewing, but for those looking for a high quality feed, including professionals using DJI FPV on set, it's not usable.
@@JoshuaBardwell Oh, I totally agree and that's why I prefaced quick and dirty. Lol
@@JoshuaBardwell I'm also curious if you were to use a USBC dongle that has HDMI out but also a USBC 5gbps input instead of sending the signal USB c to usba to USBC like you did in your video
The problem with the adapter is that the USB host device switches when the DJI fly app is used. It's not about the speed.
Ever thought about doing a proper review on walksnail now it’s on good firmware and pretty much half the price and weight.
What has better range: O3 Air Unit + Goggles V2 with aftermarket antennas, FCC and 1200mw hack or O3 Air Unit + Goggles 2 with stock antennas?
I get a feeling they are not going to fix the lost bind bug - because, if they port the vista and air unit connection to the V2 goggle firmware, they likely ration that you should not need to boot into the older DIY side OS anymore. 🤷♂️
Interesting take
Hej Joshua! Recently I found that the power output on 2 and V2 are differerent. Look at the FCC power on both systems. Can you eleborate on that?
Transmission Power (EIRP) on Goggles 2
2.4 GHz: < 30 dBm (FCC), < 20 dBm (CE/SRRC/KC)
5.8 GHz [1]: < 30 dBm (FCC), < 23 dBm (SRRC), < 14 dBm (CE/KC
Transmission Power (EIRP) on goggles V2
2.400-2.4835 GHz
FCC: ≤ 28.5 dBm
CE: ≤ 20 dBm
SRRC: ≤ 20 dBm
5.725-5.850 GHz [1]
FCC: ≤ 31.5 dBm
CE: ≤ 14 dBm
SRRC: ≤ 19 dBm
There are too many comments to check, but if you can get video to your phone, can you cast your phone to a TV? I have a 55 inch TCL Roku TV that I can cast Apple devices like iPhone and iPad to it. So essentially I can cast the goggle view if it's appearing on my iPhone, correct?
Bardwell da goat
One thing that you didn't get wrong but didn't mention is if you are new to HD and have bought into the new system with Goggles 2, unless you bought the goggles from DJI directly you will be stuck staring at your 03 air units sitting on your bench until mid January because DJI decided to withhold their retail partners stock until then. Guess they are hurting for money and really needed to get those initial sales....🤦♂️
Order from DJI, they ship super fast.
@@fpvgiggles and you get 1% back for future orders
DJI hurting for money lol
21:30 The 4:3 footage got mislabeled as 4K60 here. But it is marked 2.7K60 on the phone card, and you do point out afterwards 4:3 can't do 4K.
Good catch.
WTFOS fixed the binding bug on vista side. On o3 still need to rebind
Wow so we can use the new air unit with our old goggles 😁 thats brill
Hey Mike does it still work? I have an RC PRO but it won't connect to my goggles 2 like your video.. Any tips to get this working?
I think that HDMI adaptor does not give enough power to give you hdmi out. You might have different results with a more professional monitor
Any idea on what the max range is?
Hi great video BTW, I have a crazy question, is it possible to use this camera as an action camera only, without video transmission. and powered from the USB C port, I like the size of this unit and it would be great to mount the camera on a helmet and stick the main unit on the side of the helmet and power through a USB connection, and the price is great, so is it possible to opperate this without goggles. In other words power up and start recording from your phone ??. Also would the on screen data be recorded or can it be turned off on the internal video recording.
Thank you in advance.
That’s a bit much bro.
The camera does not power up from USBC.
NOTE: using V2 when you switch back to Vista type air units you can not use audience mode until you bind with a Vista.
Is it necessary to update Goggles V2 to make them work with O3 Air Unit? If so, whether it makes it impossible to use FCC and 1200mw hack?
again, so great review, but i'm still a bit confused if the goggles 2 are supporting the DJI Air Unit and vista? in some quite recent other review, it is claimed it is not supported, even on DJI website if i'm not wrong.
It is not currently supported but it will be supported soon, expected by the end of December.
I can't get the OSD Canvas mode to work? I'm using crossfire and followed the manual to set the MSP UART 4 on and then changing the CLI files. Am I missing something?
The rebind problem to me is like DJI just trying to annoy the V2 users, force them to switch to goggle2, it really doesn’t like a bug
The 2 systems share the same memory space, and it overwrites each time you change. They're likely to fix it this update
Hi Joshua, thank you very much for the videos !! I am wondering if there is a solution yet to get video output from the DJI google V2 to an ipad or iphone using the classic air unit ?
V2 goggles yes. Look up "digiview" app on android. Not iPhone though. It doesn't allow access.
There is latency information in that srt file. Below the timestamp, there is a “DiffTime” and that is the latency. Actually the timestamp itself shows the latency, you just ise the second timestamp and minus the first one.
Are you sure?
How is the air unit supposed to know the latency at the receiving end?
If you look at them, 33-33-34ms, it just tell you the delta T between log entries
It seems like only the goggles can truly know the final latency since only they know when a packet was finally received. But in the other hand, only the vTX knows when a packet was sent, and it's not like they sync their clocks or something. It's a bit of a mystery.
Ok im having trouble with my o3 air unit. When I look in the goggles everything is fine. Then I arm everything is still fine but then when I go to take off then the video connection instantly gets disconnected and then it reconnects again? Any problems heared like that before lol? I tryed changing voltage settings etc and nothing is working, I think its either a bug that dji needs to fix or my air unit is just faulty. But sometimes it Flys great with no problems. But I definitely don't like the fact that sometimes ill have to disarm because I can't see anything on take off lol. Any help much appreciated
No fan is a deal breaker for me. Kinda sucks was going to get them.
My Air Unit 03 will suddenly just turn off while I'm flying. I don't know if it is over heating, or low battery or what. Suggestions? Is there a way to get warnings or overheating and/or low battery in the new goggle firmware/OS? I have DJI googles V2 (loaded with firmware/OS to support the O3) and a BetaFPV Pavo Pico quad.
I want to use my goggles 2 with a FPV wing setup and I want heads up display like i get on my DJI. How can i do this? i know video can be done with the Caddix system but want to get the other information.
I've not flew in a few years till this fall. Your about to get me spending money again..lol
Anyone having issues with the air unit or googles recording the 0sd I'm wondering what records the osd overlay because when i first installed the 03 air-unit i was recording the osd then all of a sudden yesterday it stopped recording the osd. In my qav s and in my armattan beaver 2 different air units it says now googles screen recording failed and its only recording a clean feed now in video anyone else have this issue also.
Hello! does it have a built-in microphone? transmits the audio to the glasses? Or just record it. Thank you and very good your video!
No, it doesn't do either.
For Dji o3 unit googles 2 is better option for you Joshua?
Hello.Is the lens of the camera replaceable?
Can this unit be powered by a separate stand alone battery? If so. 1s 2s?.
If im flying with the o3 would anyone recommend using the dji controller? Im currently using the q7
I wish you would have tried a c to c cable on the v2 goggles to use digiview.
I think I did, didn't I? The V2 goggles work with Digiview.
Josh Prince of FPV could you do a DJI round up? I have a set of goggles v2 and I dip in and out of the dji news is there still firmware updates that people shouldn't do like in the past or is it all safe now??
Now that Butter can roll back firmware, it seems like there's no risk of locking yourself out of Root.
sorry worded the last comment and ? wrong so my googles 2 were recording the osd now it says osd could not be recorded wondering its got to be a googles issue im on the newest firmware unless one dropped i don't know about just weird it says cant record osd in the bottom right corner and it says it with bolth air units ive also got the avata and this has never happennd so is it the air units or gooles weird going to fly my Avata soon as the rain lets up 2 days of it now BS hate winter. well gonna try it and see very weird first issue ive had since i got the new system and googles..
and Joshua (too) did learn something today ;)
Which DJI Assistant did you use to flash the firmware to get the OSD running on the v2 goggles? Cause it doesn't work in my case...
Hi, my airunit O3 is very hot, I can't figure out how powerful it works. I have the FCC hack installed. The power meter showed ~4w in lower state mode and ~12w without it. Can I see the transmission performance in some software?
I didn't observe dynamic power changes. The power consumption doesn't differ when in close proximity, even when the signal has almost disappeared. I don't like this approach because why should my airunit O3 operate at maximum power when it's only 5 meters away from me?!
Great Info thank you, I have a DJI goggles V1 & ten air units/vista's. With this new firmware update will my air unit's still work with the goggles v1? I do want to buy the 'goggles 2' but still need my goggles v1 for analog.
None of this impact the V1 goggles.
@@cafub2650 what if I buy the goggles 2 and update my air units firmware. Will my old goggle v1 work with those air units?
MadsTech said that the FCC hack doesnt work on the latest beta firmware... and that the channels you can see are not related to the transmit power... this is VERY confusing. perhaps you can dig more into this.
