Please tell us a bit about your UAV interest

Multicopters for fun (aerobatics). Winged drones for photo (still in contruction).

Søren Kuula commented on Eric Compas's blog post APM response to catastrophic air frame/wing failure?
"Implementing autopilot behavior switch on an already dead airframe - would that not introduce more risk than it would mitigate? Like if it falsely triggers etc.
But it would be nice to have a working post crash detection and shutdown, which might…"

Søren Kuula commented on Trent at MyGeekShow's blog post USA Trip - Day 5 - The End
"Rana, have you seen the implementation of how the automatic altitude deduction is made?
It is (in my opinion and experience anyway) too complicated, too error prone and too confusing. Among other things, APM keeps a variable of the home altitude, MP…"

Søren Kuula commented on Trent at MyGeekShow's blog post USA Trip - Day 5 - The End
"Love your initiative :) - But do always use absolute altitude, unless you just fly a small copter in small circles. I learned it the hard way too, in Swiss mtns."

Søren Kuula replied to Kristian's discussion Almost got killed in the office today. Log file attached..
"Did u accidentally plug it back in reversed?
Yeah I had similar experiences with smaller copters. One with an APM1 leapt off a table and kamikazed into the costliest enemy installation around, my laptop. Turns out that under some circumstances, it…"

Søren Kuula replied to Jerry Hatrick's discussion Massive instability on take off.
"Was gonna say the same. It looks sooo much like a 45 degrees off error, ie, an X copter configured as a + or opposite.
OP please check that. And you can remove propellers and check that only the front one motor (+) or both front motors (X) speed up…"

Søren Kuula replied to airmazingvideo.com's discussion Pixhawk with BaseCam (AlexMos) SimpleBGC Gimbal
The last time I looked, the gimbal control code in ArduCopter was for controlling an old style servo gimbal, with stabilisation and all. The SimpeBGC does not need any of that.
I suggest you run a servo wire directly from your receiver to the…"

Søren Kuula commented on Søren Møller Dath's blog post Aerial mapping and surveillance of agricultural fields at Aarhus University
Well fell free to ask me. I an an AU alumni :) - Computer Science. I am not in Aarhus any longer though.
I never had the Bormatecs but I know them from a friend. He cut his Maja up and moved a section or the forward fuselage to the rear, to get…"

Søren Kuula commented on bigkahuna's blog post I may have just witnessed the future of personal drones...not sure if I like it
"Don't worry too much, what happened there is not the future. It is a phenomenon that will end as soon the novelty wears off and those, ah, idiots will find some other way to believe they appear cool.
Also, the photos or vids from 10 ft over peoples…"

Søren Kuula replied to David's discussion 3DR Power Module Limits
"Hi, I also think that sounds a little bit extreme, even for that weight. There may be room for improvement."

Søren Kuula replied to Patrick B Lawler's discussion Firmware connection failure
"Hi, firmware update works only through USB.
The reason is that the bootloader, which is the only software component that can do the job, is only active for a second or so after reset. The USB serial port on APM and on Arduinos is therefore made so…"

Søren Kuula commented on Chris Anderson's blog post New APM-powered ready-to-fly FPV plane
"It's quite some larger (198 cm) than an Easy Star and looks okay. The small pusher props are neither very powerful nor efficient though. I once cut the whole tail off my ES and glued a thin balsa tailboom under the fuselage to make space for an 8…"

Søren Kuula replied to Hugo Pereira's discussion The luckiest fly away ever
"Hi, funny story but really you have now learned that YOU and not the SW is the pilot in command.
Please learn to fly it well manually, so well that you are confident to take over in manual any time. Also when it's nose in etc.

Søren Kuula replied to Guerrilla Drone's discussion APM 2.6 Orange Blinking Light
"Hi, I vaguely remember having been in this situation and having pulled the SD card out and read the boot.log file. And having found useful information there about a HW error I had, which caused it (bad compass wires in my case).
I also remember that…"

Søren Kuula replied to Benjamin Harvey's discussion minimOSD no mavlink data. SR3 missing?
"You can write the parameter settings, and then pull the USB cable. As soon as the USB is pulled, that should cause the output to appear on the telemetry port instead of USB (the smaller PPM encoder CPU takes care of that).
I'm not quite sure about 2…"

Søren Kuula replied to Remus Avram's discussion Serial Buffer very laggy! Can you explain why?
You do know the radios break the byte stream into frames and can send only whole frames, right? The 3DR radios can be set to look at or not look at the MAVLink message boundaries when doing this, in order to avoid splitting MAVLink messages over…"

Søren Kuula replied to Leandro Chaves's discussion Driver Arduino Mega 2560 do not work with WIN 7 ?
"Do you have VirtualBox installed on that? I sometimes suspect that it messes things up.
I'm planning to get rid of Windows altogether, maybe you want to join me? :)"
