Although both iOS and Android devices allow developers to get access to gyro/accel/mag data fusion output, it's not as low-level as developers of autopilots would like. Make Windows 8 will get closer.
You'll need 4 rubber rings ~1.5-2cm diameter, ( used on prop-savers ) and 4 M3x10mm Spacers.
Just squeeze it through the hole:…Continue
The folks MAVlab team from the Delft University, faculty of aerospace engineering, have been actively involved in the paparazzi community. They have been part of the the paparazzi community since 2006 and have different MAV projects running in the lab. The subjects of thier projects have covered a very wide range: From swarming over autonomous spot landing, Hybrid uav`s (quads with wings), flapping wing (www.DelFly.nl), fixed wing, rotary wing, electronics…Continue

It's free and open! Current issue has an interesting paper on sensorless control of DC motors with a Kalman filter.
The journal covers:
"...international activities that relate to the design (mechanical, control architectures, actorics, sensorics...), experimental results and applications of:
A perfect combination of my twin passions, 3D printing and copters! From Hackaday:
If you’re like us, you’ve been infatuated with the small RC helicopter you picked up on Amazon up until the point where it careened off a wall and broke its…
Firefly Mark One Flies in TREX Configuration. It's like a Space Odyssey!
As you can see above the 3D printed frame project has advanced one more step. I have fitted the 3D printed hub with 4 cut down TREX 450 (12mm) tail booms. It's being flow in Stability Mode. Just a note on cutting the…Continue

I've been experimenting with using an Arduino-powered vision system to detect and locate point light sources in an environment. The hardware setup is an Arduino Duemilanove, a Centeye…Continue

Andrew Tridgell ("Tridge") is a well-known programmer in the open source world (Samba, etc) and one of the leaders of the APM dev team. His UAV team, CanberraUAV, will be competing in this year's Outback Challenge with an APM-powered Telemaster, and at the…Continue
Hello! This is our first UAV video and some clips from our first flights. We never done anything like it and you will enoy the crashes :p Our prodject is to build a UAV with the beagleboard mini computer, wify, 3g, auto pilot. But for now we
will have to learn how to fly RC,
Pictures can be found on our facebook page, just like…Continue
The items shown above are part of a 5.8GHz video transmitter (#5) setup offered by Range Video. All items are sold as individual items and like a big dummy I forgot to get Santa Clause order their powersupply (#4) when she placed her order for the transmitter.
So the luck of the Irish kicks in and Mr. Murphy ordered their last Filtered Linear Power Supply and there's no telling when they…Continue
That there is the culmination of 30 months of off & on, hard work. The 1st stable hover of the Marcy 1 monocopter, under computer control. The last items were getting the takeoff as stable as possible, getting the altitude as stable as possible, aligning the azimuth as close to the camera angle as possible, & trying many PID values. Not only…Continue
This week I focused on getting the Nova ready for the FPV system I'll be installing, and it flew great!I added a new wing that has a larger wingspan (62in.) and better locations for the ailerons (closer to the wing tips for greater leverage). This added a little more stability, slowed the airplane down a little, and allowed for the additional weight.
I also tested the wing loading by using the heavier battery (a 4.4Ah battery that weighs in…Continue

Some interesting videos of my morning flights with the latest firmware and APM2.
Dont forget to watch the last video ;)
Arducopter, now with REAL chicken sound effects...
Loiter worked quite well considering the drift issue...
It only started to drift after a while.
Very impressive design and what looks like top-quality components. [UPDATE: It appears to be a stock Xaircraft frame that costs $160. Thanks to the commenters for catching this].…Continue
DISCLAIMER: This could be dangerous and might crash your copter.
OK! I made some new changes to the autotuning algorithm and I have tested it again in the simulator. I think this is ready for some real world testing from some VERY BRAVE users, or some simulation testing. Unfortunately I do not own a quad and my octo is out of commission until Tuesday, or I would be testing this right now outside.
FPV is the greatest way to discover places while you're on vacation. In the next few weeks and months TBS is going to present a couple of vacation videos ... here's the first from the Maldives, piloted by RiSCyD.
If you have quite a wedge of loose change down the back of the sofa this might be a fun thing to purchase!
