andreas kellermann commented on Chris Anderson's blog post Intel gives sneak peak of drone development board
"250$ for a complete x86 based flight controller with camera and hd link in a tiny package, sounds like the Pixhawks will be outdated very soon?"

andreas kellermann commented on DROTEK's blog post Drotek releases first L1 RTK GNSS compatible with PixHawk (ArduPilot/PX4)
"Great Project!

@Emlid
Maybe this helps motivate you to put some more effort into the reach project? I mean the software is still beta at best and the Pixhawk integration is nowhere. Also your "todo" list on your wiki looks pretty much the same as…"

"Hello Terus Team
I would volunteer to compare your RTK solution to the reach system, with which I have been working for the last couple weeks. 
I`m building copters and planes as a hobby for 5 years now (mapping and photography). Currently I`m a ee…"

"They had a discussion on the Emlid Reach forum about the Pi Zero. The Emlid team said it would be possible to use with their Navio2 shield, but currently you would need an adapter cable to match the Zeros pins to the Navio.

The zero is pretty much…"

"Raspberry pi 2 i/o shield are already available and offer 1GB of ram. Not that much bigger than a pixhawk. Or use the raspberry zero with a custom shield. Tiny.
So instead of using a lot of resources fixing the Pixhawk it wouldn`t it make more sense…"

"Because they tried to squeeze more and more code into the original Arduino chips. Which was obsolete for years anyway. Trying to program everything as efficient as possible makes development very slow, as Randy already stated.

Also I`m a bit…"

andreas kellermann replied to Chris L's discussion Pixhawk with DJI Lightbridge
"I haven`t found a option to control non DJI gimbal via gimbal port. You can still use the SBUS channels. But you lose the option for the second transmitter...

No non DJI OSD either, as far as I can see.

I paid about 1300$ when it first came out…"

"It just shows that the hardware itself is cheap. You pay so much for the lightbridge 1 because it was the first affordable system. And now you pay as much for the lb2 because after you realize that your phantom is too small for a better cam / you…"

"USB 2.0 is 10Mbit/s isn`t it? Recommended bitrate for 720/1080p is about 15/25Mbit/s for good quality stuff. So it might be a problem. I found the quality on usb worse than on a direct hdmi screen but I`ve never tested it objectively.

Also, the…"

"Maybe if you get it a lot cheaper. I just don`t think HD link was worth that much money. And then you only got one air unit which is a pain for planes where the air module is buried in the fuselage and it takes ages to switch them to another plane.…"

"Sounds great. Where did you get that information? I haven`t seen much details about the internal workings of the Lightbridge system. I was really tempted to tear one down for a while to see if there is anything which can be read out. But the price…"

"Well not a normal plane but since I`m rather confident in the failsafe / RTL mode (Usually I crash the plane 9/10 of the time) and I never had a RC signal loss on the lightbridge (so far) I`m fine with the Lightbridge.

Wouldn`t buy it again,…"

andreas kellermann replied to Bill Piedra's discussion New RTK GPS on Indiegogo
"Interessting. Emlid has told me that they will use Golonasss/Beju and later on Gallileo as well for their RTK solution. Since as you say the number of satelites with good reception is critical.

The trouble with that is that the update rate of the…"
