I was able to reproduce your observation here on my desk with a Flip32 FC. Same thing: 3D-OSD present with BF 3.0.1, no 3D-OSD present with BF 3.1.5. I dived into the Betaflight code on GitHub a little bit and while searching around I came across a chat protocol dating back to October 26th, 2016 in which one of the core developers states:
Quote:
... serial port is no longer used by mspFcProcessInCommand and mspFcProcessOutCommand,...
See the full chat here (https://gitter.im/betaflight/betafli...ves/2016/10/23). In addition and following this Betaflight/OSD introduction (http://www.propwashed.com/betaflight-osd-setup-guide/) it really and sadly looks like, that the old MSP code (used by MinimOSD) is completely gone with Betaflight 3.1. That is of cause a big pity. As long as this this status holds true, I fear, that the 3D-OSD features of all NerdCams will be non-functional with Betaflight above 3.0.1.

I don't know if it helps, but an alternative would be to use a RE1 flight control (https://www.brainfpv.com/re1/). It supports a native OSD, also in 3D (side-by-side only).

I know this, having OmnibusF4 in one machine.

Is there any chance to bring this code back, or we can only cry and replace all FC if we want to see battery data to prevent going down empty?

Not yet. In order to clarify things and possible options I have posted an issue for the Betaflight team. Let's see what the response will be.

Looks like I need to update the MSP core in my camera firmware. My present implementation is too strict in the sense, that the message length for legacy MSP messages must not and will not change.

Now both Cleanflight and Baseflight developers have decided to append new data fields to legacy messages , thus making the message length longer than the expected, instead of creating new non-legacy messages for this purpose. My position is too weak to argue against this.

@ jaba_cz: I need some days for preparation of the new firmware. I'll contact you when it's done, then we will discuss how to deploy the new firmware to your camera.

Firmware update done. Camera OSD now works again with the latest versions of Betaflight/Cleanflight.

Interesting news - there is a new alternative to FatShark's 3D-capable goggles - the AOMWAY Commander V1 (http://www.aomway.com/en/product/com...1-fpv-goggles/). SeByDocKy was so kind to perform a successful compatibility test with a NerdCam3D Mk.2. See his findings in the following video.

Hi Michael

Which goggles do you think best matches the Nerdcam? When I say best match I mean the optimal balance between large FOV but not so large that the (640 x 480 I think) camera resolution looks bad. I am ruling out 16:9 goggles as I do not want any stretch (Dom V3, Aomway, Skyzone).

Possible goggles to choose from...

Fatshark Attitude V3
Interlaced 3D, 640 x 480 screen, 32║ FOV
I use these already with my EMRLabs 3D camera and enjoy it a lot but I am getting greedy for a larger FOV. This is my baseline comparison. Is there something better in SxS mode?

Old Fatshark Dominator HD2 (ebay $400 ish)
SxS 3D, 800 x 600 screen, 50║FOV
The screen resolution is more than the camera but the 50║ FOV might be too much up scale and look pixelated.

Fatshark Dominator HD3 ($500)
SxS 3D, 800 x 600 screen, 42║FOV
(Need to adjust for goggles bad centerline)
The screen resolution is more than the camera but again the 42║ FOV might still be too much up scale and look pixelated. If I had to guess these would be the best experience with the Nerdcam.

Zeiss Cinemizer
SxS 3D, 870 x 500 screen (666 x 500 in 4:3 mode), 30║FOV (ebay $350 ish)
I read these black screen with bad signal - that would rule them out. Otherwise maybe not that much better than attitude V3 and less convenient because a ground station is needed.

What FOV do you think gets the best out of the camera?

Any other goggles?

I'd opt for the HD3 as well. There is not much choice if 16:9 goggles are ruled out.

At the moment I'm using a HD2 and I cannot complain about any pixelation. The internal 800x600 displays are fine enough and interpolate incoming analog video well in my opinion. The FOV is really huge, maybe a little bit too huge, such that a slight reduction as seen with the HD3 should be perfect. I use -2 diopter inserts.

In case the centerline is not perfectly matched use the compensation feature of the NerdCam. This works pretty well. Downside is that the DVR footage also will be uneven.

The Cinemizers are not too bad, in particular the OLED, but I personally find it very convenient to have a receiver inside the goggle.

Take the HD3, Phil.

Thanks for the confirmation. The bonus of HD3 is that it can switch/crop to 16:9 for a connex connection as well.

KritzelKratzel I do not know if you are monitoring this page but I am interested in your most up to date version of the NerdCam3D Mk.2 Stereoscopic FPV Flight Camera.

I understand they have been discontinued which I feel is a shame as I just found out about it.

If you are not going to continue to manufacture and make them better would you consider open sourcing them or at least sell us all that is needed to make them for ourselves such as plans, PCB scale drawings, component placement and a comprehensive parts list for a reasonable cost along with the most up to date software for it.

I really hope you are monitoring this page.

I am sure Kritzel will reply but if not and you still need a stereo camera let me know....
