Christian replied to Paulo Neves's discussion Sony Alpha5000 APM triggered and geo-tagged in Terrain/Surface Mapping
"@Oscar: This is only half the truth ;-)
AFAIK,
- Sony QX* camera series can only be controlled via Wifi and the Sony Camera API.
- However the QX* and other newer Sony models have the proprietary Sony USB Multiport connector. There are a few…"

"Which libraries do you use on the companion computer?
Do you control everything via the USB port? Or do you need the Wifi too?"

Christian commented on Simon Howroyd's blog post Efficient Powerpath Balancing for Fuel Cell Battery Hybrid Powertrains
"Thanks for sharing!
These designs may be also useful for automatic power switching and not only for balancing?
Arguably the most common cause of drone crashes is a power fail due to empty/bad/damaged batteries !?
Therefore, i recently thought about…"

Christian replied to Bill Bonney's discussion Single Board Computer SD Card Image- Software Laundry List in Companion Computer Working Group
"Why this Ubuntu version and not Ubuntu Snappy Core ?
Furthermore, for the Raspberry Pi i would rather suggest Raspbian respectively Raspbian Lite (headless version) !?"

Christian commented on Peter Koppendorfer's blog post how to land in Germany
"It is also one of the techniques that EMT uses for their LUNA drones to land safely.
The LUNA drone is widely used by the german armed forces.
However i think a huge net is a quite laborious setup if you also can land safely on the belly in the…"

Christian replied to Martin Rüedi's discussion Project FlightZoomer: low tech, COTS, smartphone based telemetry (+more) solution in Telemetry over cellular IP
"I agree - dynamic DNS is not the challenge.
The problem is the data transmission between two mobile devices without a relay server. It heavily depends on the NAT/Firewall used by the mobile ISP. Afaik, it is almost impossible to communicate directly…"

Christian commented on microuav's blog post Hijacking drones with a MAVLink exploit
"I remember there was a discussion about secure Mavlink (sMavlink) started by Lorenz Meier in 2013.
I don't know what was the result of this discussion...
And i found the SMACCMPilot project, that uses a secured Mavlink communication:…"

"This link works... huuh, very large manual ;-)
On your website i see for example the following link which doesn't work:
flightzoomer.com/includes/..\downloads.html
Maybe this is a browser or OS dependent problem, i am using Firefox 41.0.1 under Win…"

Christian commented on Daniel McKinnon's blog post Would you like to capture professional quality photos with Solo? Do you like Rube-Goldberg machines?
"@Benoit: Eeehm, this is not USB... ;-)
It uses a modified USB connector just to trigger the camera. You cannot control anything via USB...
It would be great if you can do the same via USB that can be accomplished via the Wifi API."

Christian commented on Warren Eather's blog post Multi-Point Repeater Aircraft
"@Tridge: You wrote: "The MAVLink forwarding rules in ArduPilot will get the packets through, as long as the two aircraft have different sysids."
Can you please clarify: If i connect one RF module to telem1 and a second RF module to telem2 on a…"

"Is there any solution available, that can control and trigger a Sony camera via USB? Or maybe another camera (not DSLR) from a different vendor?
I would like to connect my Sony cameras to a Raspberry via USB, but afaik there is no USB API available…"

Christian left a comment on Telemetry over cellular IP
"@Bernt:
Just a short question:
Have you measured or estimated how much data volume you need for your video stream and telemetry transmission (e.g. in Megabytes per second, minute or hour)? Because most of the SIM card flatrates have daily or monthly…"

"Nice gadget, but quite useless for drones so far...
We need an interface, drivers and SDK for connecting this to a linux based companion computer e.g. Raspi, Odroid, Edison..."
