gimbal brushless motor project

Hi everyone

My questions are about the gimbal brushless motor project by Martinez

1- what's the motor used in his project is it BLDC or servo, if it's BLDC how can he control this motor , what are the sensors used to control the 60 degree phase of a BLDC, i didn't find hall sensors, is it by gyro, accelerometer ??

2- I didn't understand the program of Mr martinez because i don't know the ardiuno language, and the code is very long , can any one give me a flow chart to this program?

thanx

Are we supposed to know what project you are talking about?

Is there a website dedicated to this project ?
I found the original post by Mr. Martinez here:

I do not know what this is : http://brushlessgimbal.de/

The code and schematics are now at SourceForge : brushless-gimbal-BruGi download | SourceForge.net
I took a look at the file: BruGi_050_r207.zip
and the i2cdevlib is used for the MPU-6050: http://www.i2cdevlib.com/

I agree, the code is very long and complicated. Sadly I don't know that board.
Is there documentation for the board ? I can not find it.
