William Premerlani left a comment for Fabien Bruning"Hi Fabien,
Here is a link to my discussion on wind estimation without a pitot, and here is a link to my paper.
Since then the method has been thoroughly tested by many pilots and found to work reasonably well.
Best regards,

Fabien Bruning replied to Oyvind Dahl's discussion We consider offering radar altimeter for UAV's"I suppose there are really two kinds of UAV markets: the diydrones community hacker kind and the professional user who just want a closed box.
The thing is, I think, the user wants a complete quad that works out of the box, so doing an open source…"
Fabien Bruning replied to Zachary Eldridge's discussion Who wants a Iphone App used as a ground station with Mavlink?"Nice, I tried serial interface through ssh and Minicom on a jailbroken iPhone once (to have one phone in the plane and one on the ground).
It worked a bit, but 3G lag was immense."

Fabien Bruning replied to James Printer's discussion Rotating object at 60RPM"You can get relatively cheap optical encoders (about 30$) that give your Arduino the rotational speed. Simply take the desired speed, subtract the current speed and multiply that by some suitable constant. Output that to PWM and it should work. (the…"

Fabien Bruning replied to Ellison Chan's discussion Brainstorming Specifications. in the group DIYDrones - CNC Project"That's the same tech I mentioned, and he's completely right. Not to cut your buddy out, but I already ordered from the manufacturer directly and they ship quickly.
One disadvantage: they're pure SMD components and they don't…"
Fabien Bruning replied to Ellison Chan's discussion Brainstorming Specifications. in the group DIYDrones - CNC Project"Couldn't you make a "bridge" , so that instead of moving the gantry you'd have only a moving bridge up top? That's how most commercial machines I know work, for example this…"
Fabien Bruning replied to Monroe Lee King Jr.'s discussion Drawings of the machine in the group DIYDrones - CNC Project"That's a very generous offer, unfortunately I can't seem to find the Hong Kong new ones, they only have linear ball bearings.

Fabien Bruning replied to Monroe Lee King Jr.'s discussion Drawings of the machine in the group DIYDrones - CNC Project"Hm, I haven't calculated it but you're right that straightness was the first thing I was going for. I wonder if those eBay dovetails are any good."

Fabien Bruning replied to Ellison Chan's discussion Brainstorming Specifications. in the group DIYDrones - CNC Project"Why use stepper motors? They are inherently an open loop system, where you prescribe a certain amount of rotation to the stepper motor while you hope the gantry follows your model of rotations -> linear translation.

iPhone telemetry: a short tutorial
Posted on April 22, 2011 at 8:13am 7 Comments 6 Likes
Hello everyone,
After experimenting with tuning the APM, a friend (Roel Offermans) and I decided to implement telemetry. Even though it may seem counterintuitive to use a phone rather than an Xbee, when you already have the phone it saves some money. Another advantage is that it has 'unlimited' range,…
Continue My first Mega flight
Posted on August 8, 2010 at 8:40am 6 Comments 0 Likes
So after first connecting the engine the other way around, rain , and more rain, I finally managed to make my first flight in Stabilize mode. With just P-control on a Wingo clone, both at 0.06, it manages to maintain it's height perfectly, but it rolls around a bit.
Guess upping the P was a bit enthusiastic! I'm not posting anything revolutionary, but I'm very happy it flies :)
Picture of the APM mounted inside the plane, no video,…

i saw one of your post about a cheap quad, i have motors ESC frame, remote etc with me, but confused about board and sensors, can you plz tell me which board and sensors u have used?
