Quadcopter - Raspberry Pi - Arduino - Esp8266 and more

Yesterday morning, I did my first flight test out. 2 problems: My phone LG3 loses the wifi hotspotan then I can no longer control the raspberry Some propellers randomly do not start or not at the same speed as the others This morning, try again To correct my previous problems, I tested with my wife's Honor 5C phone. No more loss of wifi ;-) Instead of plugging the raspberry on the beak of an ESC, I plugged the raspberry on an external battery. No more problem starting the propellers. But the tests were not very conclusive ... The QuadCopter has indeed raised too much on one side. The other side did not stand up. So he tipped over and flipped over. This resulted in the breakage of 2 propellers. I still struggled to interpret the results of the logs because I do not know which side it rocked. In the future, I will have to film the flight so that I can analyze it later Here are some graphs of my simulations First test : I lean the quadcopter forward by 30 degrees...

Building a Quadcopter using Raspberry Pi... The idea came to me during my holidays by reading an article by Andy Baker in the MagPI newspaper (numbers 19 and 20) On reading the article, a quadcopter appeared to me very simple to build. And then, according to my research, I realized nevertheless that there are a lot of knowledge to know and that it will be quite complicated .. . So I bought the material on ebay: The F450 frame The 4 motors The 4 propellers The 4 ESCs The LIPO 3S battery The MPU6050 (gyroscope / accelerometer sensor) F450 kit The MPU6050 (gyroscope / accelerometer sensor) For the flight controller part, I use a Raspberry Pi 2 that I already have. As passionate computer scientist, the idea is to program the Raspberry to drive the engines according to the MPU6050 sensor which will provide me informations on tilt and acceleration. So, I will not want to use the CC3D flight controller provided in the kit. For the remote control, ...
