PS4 Wireless controller via bluetooth
Hi Guys! Just got my Dualshock 4 controller to work with bluetooth connection on OSX. I updated client to use PySDL2 bindings instead of pygame to take advantage of latest SDL2 which supports PS4 controller connected wirelessly. If anyone is interested, code is at https://github.com/ak1394/crazyflie...

Re: ms5611 barometer usage - more altitude hold
BTW, looking at your code it seems that you reading pressure and temperature in one go?
I briefly played with it as well and I was getting the best results when alternating when reading temp and pressure.

Re: 10DOF model sensors
I twisted motor wires when assembling CF, so I have never tried it with the untwisted wires. Also wires are a bit longer than they need to be to reach the motors, and can be moved around a bit. I have suspicion that moving the wires affect magnetometer, so if you have calibrated it and then moved th...

Re: 10DOF model sensors
I was flying outdoors with the heading lock on, which is quite fun - you can trow CF up in the air - in almost in any orientation like sideways, hit the throttle and it steadies itself and rotates so you know where the forward is, and you ready to fly it. In the process I crashed it, hitting the gro...

Re: 10DOF model sensors
I got some results using the magnetometer data. With my current very hackish changes to (mostly) the client, I can lock heading of CF and fly it around the room with its front always pointing the same direction. If I manually rotate it with joystick, it returns to pre-set direction in a few seconds....

Re: 10DOF model sensors
That's something I thought of doing, nice to know it wasn't such a bad idea. Magnetic fields generated in flight don't seem to bad (although I did quite limited testing so far) it seems that running motors on the increasing speeds simply adds to magnetometer readings depending on the speed, so hope ...

Re: 10DOF model sensors
I'm trying to calibrate and tilt-compensate magnetometer at the moment, seems quite challenging considering magnetic field distortion present indoors.

Re: GPS receiver extension
I wonder what's the point of adding GPS considering very short flying time of Crazyflie?

Re: 10DOF model sensors
One idea is to limit the thrust lowering to avoid the Crazyflie dropping like a stone when you release the thrust ... This is a good idea! However before I can try something like this, I want to make sure I'm getting solid sensor readings. It looks like (by simply observing values on the console) b...
