"I've had similar incidents with a bixler. They develop nasty stall behaviour with some weight on them, especially if the weight isn't centered laterally. You have to level the wings using rudder and aileron before applying up…"

Getting body-frame accelerations from X-Plane

Hi all,I'm currently working on hardware/software in loop simulation for my Android autopilot. I've got UDP packets flying back and forth over wi-fi between X-Plane and Android, and it works…Continue

Thanks."
johnm545 commented on Hai Tran's blog post UAV Multicopters safer than other model aircraft?"Personally I would not want to be within 5 meters of a large multi-meat-slicer-copter. MTBF of hobby-grade motors and ESCs is probably in the tens, maybe hundreds of hours. 8x the powertrains = 8x the chances of a failure. Hope your…"

segf4ult commented on johnm545's blog post Running an autopilot on Android"Hi John, very interesting project. I signed up just to comment XD. Using the mobile network is definitely the way to go in order to perform long range missions. Here are my two cents as Android programmer:
The phone doesn't need to be the…"

All the code is in an activity. Lack of real time doesn't seem to matter, it's got plenty of CPU grunt to stay on top of…"
Hans Cappelle commented on johnm545's blog post Running an autopilot on Android"@John Moore: on your tablet for sure :p
I like the idea. Is it fast enough? Bluetooth isn't very fast and then you're running on Android, no real time processing."
exporulez commented on johnm545's blog post Running an autopilot on Android"Nice work :D Have you made a simple Activity running all the code? Some Android phones have more than one core. Have you decomposed the system to use parallelism? I know that linux kernel offer RT call for the scheduler. Maybe there is a way to use…"

johnm545 commented on johnm545's blog post Running an autopilot on Android"@Chris: I plan on releasing the code at some point, but want to clean it up a bit first. There's some big chunks of code with no comments and some "workyouf$&$#&%" variable names floating around in there.

Savraj Singh commented on johnm545's blog post Running an autopilot on Android"you could also poll a url... but that's totally a hack. ;)"
Carl Clegg commented on johnm545's blog post Running an autopilot on Android"You could also use a reverse ssh tunnel through a publicly accessible server."
Savraj Singh commented on johnm545's blog post Running an autopilot on Android"why do you need public IPs from the telco? You can send a 'push notification' to your app from a server. On iOS it's the push notification API, not sure what it is on Android but there's an equivalent."

Running an autopilot on Android

Here's a fun little project I've been working on for ~6 months now. It started when I looked at my phone and thought this has everything needed for an autopilot - 3-axis gyros, accelerometers, magnetometers, GPS, fast CPU, plus a nice big touch screen and more wireless modems than you can point a…

Hi folks,
I've been working on a small C# program to enable hardware in loop simulation with FSX. It's working nicely now, so I've posted the code up at http://code.google.com/p/fsxio/
I've been using it to test my Android…
