DIY quadcopter – trying a manufactured controller

After a lot of problems and a lot of failed attempts with my DIY controller, I decided to buy one to understand what’s wrong (and also to make it fly !).

I decided to buy the Flip32 (AfroFlight NAze32) because it was based on Arduino (MultiWii) and it seems to have a lot of interesting features (magnetometer and barometer, battery monitoring , possibility to implement ultrasound sonar …).

It was also the occasion to discover a sensor that I’ve never used before the barometer. I know how it works in aviation (it is what is used to know our “altitude”). However I was astonished to see how precise it is ! It can detect variation of a couple of centimeters vertically only with atmospheric pressure.

For only 29€, I bought it in order to see if it could make my drone fly. Right now it is flying in gyro mode but the stability is not great ( so a card is not that much better than me :P). However with a card it is easier to have physical vibration damping which is the next step.

I’ll try to experiment a lot with this new card, but I’ve not given up the homemade controller.
