Erik Unger commented on Egor_FPV3DCam's blog post New 3D FPV Camera - in the DEVELOPMENT process
"A fixed camera distance that is smaller than the typical eye distance is IMHO not the best idea."

Erik Unger commented on Chris Anderson's blog post Google scraps VTOL design, back to the drawing board
"It takes about 5 minutes to google what the problems of a tailsitter are. Interesting that the guys at Google didn't find out before starting the project ;-)"

"Also think you could crowdfund this!"

Erik Unger replied to Erik Unger's discussion RPM oscillations on yaw
"I found the root cause: The Multistar ESCs are loosing sync with the Multistar motors (hello HobbyKing). No stuttering with Turnigy Plush. But those are slow at regulating RPM, so I am looking for fast ESCs that work with those motors."

Erik Unger commented on Nils Högberg's blog post Oculus Rift DK2 with MavLink head tracking and HUD, the HUD (OVRPilot part 2)
"Nice. How do you digitize the video and what lag are you getting? My experiments with a USB video grabber showed a lag of 200ms."

Erik Unger replied to Erik Unger's discussion RPM oscillations on yaw
"The bad sound of the motors is _because_ of the oscillations.

Regardless: I don't get them with props removed. So it has to be some resonance between the props and the Pixhawk coupled over flexing frame. Will have to stiffen the frame.…"

"Would using an older firmware version fix the problem until rc10 is out?"

I am working on a 1.2m Quad with Pixhawk. First I had problems with the green Turnigy Multistar ESC, but after flashing SimonK they work very smooth and sensitive.Now the problem: When increasing yaw over 50% the two slower rotating motors start to…

See video: https://www.youtube.com/watch?v=7byJNPC09FEMy setup: The APM Power Module does not power the motors, just the Pixhawk via the thin cables and it delivers 5V via an UBEC to the PWM output lane so that the OPTO ESCs get voltage. The motors…

Erik Unger commented on Egor_FPV3DCam's blog post 3D FPV camera The BlackBird
"Egor it would be handy if you offer a mount with a range of typical eye distances and a way to adjust the focal point."

Erik Unger commented on Egor_FPV3DCam's blog post 3D FPV camera The BlackBird
"So what goggles can be used for stereo display of those images?
Oculus Rift would be awesome, but it doesn't have analog in so it needs a fast analog-digital converter."
