Sebastian Gralla commented on Gary Mortimer's blog post Trappy's Counsel File Motion To Dismiss
"I still don't get it why it's illegal to fly next to a statue, I mean come on, if a 5 pound styrofoam block could hurt it, it wouldn't survive a storm."

"Hugues: APM with 3DRadio -> 3DRadio on the ground which is connected to wifi -> phone

Bill: will the Fighting Walrus Radio be supported? http://www.indiegogo.com/projects/fighting-walrus-radio"

Sebastian Gralla commented on Lorenz Meier's blog post QGroundControl Update
"is there a way to change the timescale of the graph? 1s is pretty short for long term data like battery voltage and current.

I like the new version :)"

Sebastian Gralla replied to Bryan Galusha's discussion What features are most important? in Fighting Walrus Dev
"Camera control would be a great feature.
One person flying on RC and the second person could control the camera gimbal."

"still no update on this? i have one of these adaptors, will it work with APM2.5?
I assume if it would they would still be available..."

Sebastian Gralla commented on Colin's blog post Ardustation Mega with Graphic LCD
"Hey Colin,
I gathered all the files I found, they are uploaded right here.
It uses the GLCDSS library from savitch (arduino forums) for easy 3D rotating. It is contained in my uploaded file because one can't find it anymore.

Hopefully my files can…"

Sebastian Gralla commented on Colin's blog post Ardustation Mega with Graphic LCD
"I once wrote a code for a graphical groundstation (back when Arducopter was still in alpha stage, without Mavlink)
I never got to add Mavlink support. What it has, is a rough 3D model of a copter, showing the orientation of it in mid-flight, got abo…"

Sebastian Gralla commented on yann.B's blog post New and simple way to make 3D moves without complex mecanism .
"You could save a Quad with one motor/prob breaking down, it would spin like hell, but still stable and safe for landing"

Sebastian Gralla replied to Robert's discussion Downgrade APM2 firmware
"connect it to the APM planner and check if all settings are correct, you most likely will have the erase the eeprom and restore to factory settings and then go from there, do you remeber the working PID settings?"

Sebastian Gralla commented on Chris Anderson's blog post "Think GPS is cool? IPS will blow your mind."
"Ric: maybe you accidently deactivated GPS with 3G? on my iphone, it does not matter if 3G is activated or not, position accuracy is exactly the same"

Sebastian Gralla commented on Chris Anderson's blog post "Think GPS is cool? IPS will blow your mind."
"well.. in iphone uses wifi for that
don't trust me? go into a building, deactivate wifi and search your location, it will ba very weak, now activate wifi -> you will get ~2m precision if there are a few wifi spots around ;)"

Sebastian Gralla commented on ARHEXA's blog post 3.3 million microFarads help your servos and reduces noise
"you would get better results with smaller "LOW ESR" caps, which are designed to have very fast charge and discharge rates (for filtering out noise)"

Sebastian Gralla commented on giancarlo.forum's blog post ArduPilot with ARM? IMU in one chip: MPU-9150
"well, 2.5W on a quad is a very small consuption (you take about 150W to hover)"

Sebastian Gralla commented on Azam Shahani's blog post Incredible Flight Endurance!
"as you see in the video, there is no battery dropped from the drone ;)
and they mein parallel for parallel, not for selective battery switching, that means the lipos are hardwired which menas that all batteries drain at the same time, no empty batte…"

Sebastian Gralla commented on Max Levine's blog post The easiest way to mount APM2 on ArduCopter.
"no, that adds way too much mass to the autopilot, it needs to be able to follow the movement of the frame"
