Another idea, maybe it´s more easy to control a brushless motor such as the one in this link:

http://www.maxonmotor.com/maxon/view/catalog/

This motor is also used in the second video that I posted.

Exactly it does have 3axis stabilisation, this would be perfect especially if it is possible
to turn it off in flight but pitch and roll first. If I can get that to work it would be great.

So to recap:
I need a gyro/accelerometer (this can be used from the multiwii controller board)
I need a ULN2004 or Quad Hbridge depending on the type of steppermotor used.
I can connect these together but do need to programm it to get it to actually work together.

Is this correct?

The gimball will be perfectly balanced so the force needed from the motor's won't be to high,
it does need to be able to accelerate fast and smooth (as seen in the second video)

The multiwii controller has loads of inputs and exits, woud it be possible to reconfigure the
outputs to match these output pins that you talked about?

My Apologies for the large amount of questions. I'm kind of a newbie, getting it working smooth
with servo's was a big step for me, reprogramming this to accomodate steppermotor for me
quite a big project.

If I am correct I should be able to reconfigure the outputs of the MW board using the arduino tool
and connect it to the steppermotor controller and steppermotor. Do I need to program this steppermotor
controller? or is it just a sort of translator?

Well that's the point, I dont know if that's necessary. This multiwii controller uses Arduino as well right?
I tought it would be compatible in some way and that it might even be possible to connect this ULN2004 that
you talked about straight to this board.

So I guess the answer to your question is yes.

Hello John,

Thank you for your reply, It's good to know that it is possible, Can I use the multiwii code and board as a basic? this allready contains the code for
the stabilisation using a ITG3205 3-axis MEMS gyro and BMA180 3-axis acceleration sensor installed on this board:

This board is capable of controlling servo's as it is. as you can see in this video:


I am trying to accomplish this:


Thanks again!

Hello, I'm new here on this forum and got kind of intimidated about the large amount of information
that is present. I am kind of new to arduino allthough I have allready used it in my multicopters. This
is also the reason why I started this thread because:

I would like to control a gimbal for a camera ( that is possible and not that hard to accomplish)
but not using regulair servo's but stepper motors. I want to do this because I see better results
in gimbals that use steppermotors.

Is this idea possible, and is it possible to accomplish for a novice such as myself?

Thanks in advance for your help!
