Don't get it wrong, I just wanted to show that if things don't go faster is not because I am lazy. This stuff is far for being simple.

Got a brief GPS disconnected today. Came on after 2 sec. Position hold was engaged. Turned off PH and GPS disconnect warning stopped 10 sec later. Can't duplicate it again. Is this something to be concerned about? what do I replace Cable or entire GPS unit?

No one will ever accuse you of laziness Alex. You are the most prolific and accessible programmer in the OSD business. You are the primary reason I am moving to the RVOSD. I can compare features all day, but what really counts is innovation. Rate of feature improvement over time, let me call it "Feature Acceleration". No one has you beat.
I hope I can continue to throw ideas/requests at you and you can shoot them down, or implement them. I'm just happy to have your ear.

Is the GPS cable, actually the connectors. It is sensitive to twisting, you have to be very careful not to twist the cable close to the connectors. You could either get a new cable or just cut the connector and solder the cables to the GPS unit.

Thanks! The million $ question is...Since it didn't have to reset home what would happen if it was in a signal loss RTH mode and it happened?

Its usually a good idea to hot glue the connectors at both ends to reduce movement. After replacing the lead.

Good tip Thanks! My gun happens to be on now

Exactly what I need. My et osd has it and Rth would be useless for me without it because I fly above hills... so rth would bring the plane home at an altitude were I could hardly see it (500m)...

RTH waypoints could be an option? Rather easy to implement.

One awesome feature of full-scale glass cockpit systems these days is Synthetic Vision. I've been hoping this works it's way into FPV OSD's in the distant future. It's not too overly complicated either. Just pull terrain mapping data and overlay. Could be implemented in the ground station software to start.



Don't listen to me though, I'm a full-scale IFR pilot who is used to 60k avionic suites

I've actually mapped out an IFR-like approach at my field using waypoints. When the wx is right I'm planning on flying FPV IFR approaches!

For now though I'd love to be able to change the overlay color of the OSD to green, but I know that may be a HW limitation.

Are you writing all of these ideas down?

+1 My 2c

Some locations where I'd like to fly have mountainous areas. This would be a great solution.

This is good idea, the different altitude setting may be valid for loiter range: so you can set 500m altitude for RTH flying, but when the airplane hit loiter range, the altitude will descent to selected altitude... Or turn off motor, this will be safety feature as well :-)

I'm hoping the hive mind here can help me out as I get ready to maiden my RVOSD. I haven't found answers to these in the thread, so if you know the answer, please share.

1) In the debug screen for the raw data I never see any horizontal bars for the vibrations. Is there something wrong with my IMU and if so how would I tell? The AHI is working, but perhaps this is just the accelerometer part of the IMU?

2) I've somehow activated the weird debug AHI that jumps around and has little dots instead of a solid line. How do I turn this off? You can see it at the end of the video below.

Edit: This may be related. Sometimes when I restart the OSD I get Magentometer Not Found and Accelerometer Not Found. If I hardware reboot (i.e. cut the power) they come back (see the video).
(edit- video removed to stop crapping up the thread. Plus the issue was addressed in the post below)

I like the idea, will do as soon as I get my Queen bee on the air next week.

1- The first OSD sold from this batch (Hardware 5.1) have the accelerometer bars disabled.
2- The weird debug AHI shows the actual attitude, as it is seem by the accelerometers only, so you can use it to get an idea of the existing vibrations. I forgot to disable it on the first batch of OSDs sold, because I used it during the debug tests. It is toggled ON-OFF each time you set neutrals.
If you want the new graphic board firmware with this debug AHI removed and the vibration level indicator enabled, send me a PM with your email address. But that's the only change, everything else is exactly the same. Doesn't worth the change IMHO.

It is always better to do a hardware reset(cycle power), the software reset could cause a de-sync on internal comms. This is why sometimes it does show the mag and accel not detected display.

Alex could you please answer this so I know the urgency of the issue. Thanks!
