"Hi,
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…"

"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.

"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…"
"The APM/Pixhawk definitely is less robust to brownouts than standard,high quality RC stuff. Hence the warning to use suitable power supplies for them. The alternative of trying to make the APs more robust and continuing to use power with big holes…"
"Find the 2 balancing wires that are in each side of the cell in question. Make a cable that connects the + side of the cell to the + main port of the charger and the same for - . Charge as 1S with a low current.

"Hi, considering that the days of APM are almost over,
I'd suggest you try make a Pixhawk BOM instead. Or keep an eye on the other hardwares that are coming, like vbrain or the BeagleBone cape solution(s).
Regards, Søren"

"Wow, is the balloon recognition code also available in the above links?"
"Hi, don't you think the "smaller props people" mean smaller swept area, not lower mass?"
"I made this one

with Multiwii and a few lines of added code. The great thing about Multiwii is that it is simple, and it already supports plane and multi rotor in the same firmware - although not with the…"

"Hi,
Forgive my ignorance but where is the back EMF coming from? And on the (nominal) 5V rail?"

"When it hovers, does it "think" it is level? You can see the attitude on the MP horizon from telemetry data, and if you don't have telemetry you can log the attitude onboard and read or maybe replay the logs.

"I crashed my 2.0 countless times (sometimes it did itself)
I hung it - with a plane - in a tree for 11 weeks in about the rainiest spring in Swiss history (vid)
I shot it down from the tree with a golf ball cannon
I zapped it with 12 volts from a…"

"Hi Tridge,
Thank you for the very informative answer.
Okay, I feel more reassured now. I think we are some who prefer a set of well proven algorithms with known and acceptable limitations, rather than getting involved in trying out new things. I'm…"

"Hi,
Is there a story somewhere to be read on the background of the decision to implement EKF? Which practical benefits does it bring?
I ask because I would like to know what drawbacks there would be in disabling it and returning to only DCM ->…"

"Interesting. But how does this work, is the PPM converter a USB host or a device? If it is not a host, the joystick cannot be connected directly to it. If it is not a device, it cannot connect with a PC. And USB devices are AFAIK never also hosts…"
"Hi, was there a conclusion on where the 3.3V bus overvoltage on some APM2s comes from?
Some said the volt reg, and others found a design flaw where the low and high sides of a level converter were reversed.
Regards, Søren"
