I think this is near to perfect now.. BTW: It also depends a bit on how deep one pushes the propellers in. I got the feeling that the propellers who need more force to push in tend to have less vibrations. Thanks for testing. And yes I got the same feeling that the propeller needs more force to pus...

Hi rkiara,
can you make some pictures of your soldering skills on the CF (both sides). Maybe we can see something unusual.

You have to load the driver in MotioninJoy, look at this YouTube Tutorial

You're welcome :D ...Will try to change the propellers and see how the results change. That's the right way to use the mod! Maybe you can post a capture from the balancing self test without the propellers too. I try to find out if there are differences in the motor conditions too. Thanks for testing!

Hi Tobias, I'm not so familiar with MCUs. But i've managed to map 2 Dig. Out GPIO to the EXT Header and can switch it with parameters! Juhu :D But i don't know where i should call my extioUpdate() funktion. At the moment i call it in the workerLoop() :oops: Can you give me a TIP where i can call it ...

Maybe you need one of this Pololu 3.3V Step-Up Voltage Regulator NCP1402

That looks so Wonderful. I love it!
And huge opportunities!

How the balancing self test works (in short): see bool mpu6050PropellerBalancingTest(int motorId) 1. Based on the mpu6050SelfTest() 2. First measure the environment (motors off); noise only. 3. Take second measurement (100 samples of all 3 axis) with motor on and choose the max one. 4. axfDiff = di...

Crazyflie frame v1.7 finished will post files in thingiverse tomorrow... Have a look at my blog http://paulogeraldes.blogspot.com/2013/05/crazyflie-frame-v17-finished.html It is late and I need some sleep :o :o :o . Looks really great! Maybe you can replace the motor mounts and use the CF arms for ...

Hi, i want to use two digital output bits on the Expansion header. Question: Is it possible? Can I Remap e.g. EXT_SPI_xxx Pins in the FW to digital outputs? Maybe that is also interesting for every one who wants to switch on external peripherals like LEDs, buzzer or something else. I need it for the...
