Take an ESP8266 and strap a gyro, magnetometer, accelerometer, barometer and AVR with a motor controller to it and what do you get?

Because I love ESP8266's so much, I figured adding one to a quadcopter wouldn't be so bad. Not really adding it to one as much as making it the brain, itself. This project surrounds my fun with the sensor platform and 4 motor controllers that might some day fly!

Enjoy this project?

PID loops on the ESP8266? Definitely looks like a fun project!

Unfortunately because of the lack of decent math libraries and efficient floating point arithmetic, the ESP module itself won't be able to do it very well.

It took me 1.5 seconds to calculate 32bytes of information (doing simple shifts and multiplications) on the ESP. They are just no good for math work.

Better to offload that to the AVR.
