What connections do i need to make if i have a Phantom 2, Lightbridge, GoPro hero 3 (WITHOUT a Gimbal) and the 2.4ghz V2 controller?
At the moment I have it connected up as if i did have a Gimbal, and the 2.4ghz controller does not work with the phantom and i just get flashing yellow lights on the copter
I'm setting up a 1/8 scale RC truck (an Arrma Nero) as a mobile camera for shooting mobile video. I have a Ronin-M mounted in upright mode carrying a Nikon D7200 DSLR. I want to connect the HDMI output from the Nikon to a Lightbridge 2 as well as an FPV camera to the video-in on the Lightbridge 2 so I can get a driver view and a DSLR camera view for shooting.
I have a couple of questions:
1) In other threads I've read that attempting to use the standard RC controller for the Arrma truck will interfere with the Lighebridge 2 video transmission. Ideally I'd like to control the throttle and steering on the truck via the Lightbridge 2 controller. The truck uses a Tactic326 SLT receiver, which I believe drives PWM throttle and steering controls. I think I just need an SBUS (DBUS?) to PWM converter that I ought to be able to use to to connect to the Lightbridge 2 vehicle-side ("air-side") DBUS output and then directly to the controls that I simply unplug from the existing Tactic receiver. Thee is some sort of channel mapping that I need to do in the DJI Go app that hopefully I can find instructions for on the DJI support site. I have found a FrSky 4-Channel S.BUS to PWM Decoder that seems like it ought to work and have also seen DJI recommend a RMILEC high-precision PWM/PPM/SBus Signal Converter V2, which seems to accommodate a lot more channels than I need. Do I have this basically right? Can I use either of the SBUS converters?
2) Since I plan to use the Lightbridge 2 controller for throttle and steering, it would be good to know what might happen if I lose control connectivity, or whether this can be configured on the Lightbridge 2 vehicle-side. In particular, do controls return to neutral under LOS? I'd hate to see a full-throttle runaway. I'm not under any illusion that I'd get anything fancy - like the return-to-home function you'd get in a helicopter drone with a flight controller like the A2.
3) Because I need to use the Ronin-M in upright mode the DSLR will be inverted. Is there a way to invert the video that displays on the DJI Go app so that it is right side up? Otherwise I will need to modify the Ronin-M camera mounting plate to physically flip the camera right side up. This seems like it ought to be a setting in the app, but I will go through the trouble to flip the camera if I need to (making a home-brew Ronin-MX of sorts). Also, if the DJI Go App can flip the HDMI video, does it flip the FPV video as well or is that controlled separately. It's easy enough to turn the FPV camera upside down if video is merged on the transmit side.
Thanks,
Andy |
