@Andreask Nice work!
I almost finished my new brushless head and made first tests. 3 axis controllers for brushless gimbals will also be available soon. The motors are silent due to 32 kHz pwm frequency.
Thanks for that video VK, this is the sort of stuff that the Movi rig excels at.
Can't wait for the smaller versions, this tech will make GoPro type footage much more usable, especially after exchanging for less wide lens.
The video above that WhiteRabbit posted on the 10th features a new road course in my area (western Washington) called The Ridge Motorsports Park. I've ridden this track a couple of times, and it's incredible. I'd take a year's pass to the Ridge over a MoVI anyday!
Kind of nice accidentally stumbling upon a clip featuring my own stomping ground here on PV.
They say they designed their own motors. From my research. The key to good gimbals is to rewind the wires in a specific way to increase torque. Motors are very simple devices. Electromagnets being cycled on and off creating rotation. So, What are the specs on the Freefly motors, and the next thing, is what makes a quiet motor. The noise may be more a controller issue.
At NAB Freefly was kind enough to let anyone willing play with it... very cool, very light weight. Great design. Price is not for the faint of heart, but neither are $15k+ tripods or other stabilizers used in the production world.
I can't wait to play with one of these.
@Felix, nice one. I can read and learn more, thanks.
Great resource for those wanting to build a Movi style Gimbal there's info on the control board, schematics, how to rewire a motor etc....
Finding quiet and responsive motors is the key. Same for the focus. I winder about the lens type focus motors. Fast an quiet. I wonder if that technology is in higher torque motos. Someone here will find the perfect motor for us DIY. I did see a Russian video showing how to re-wind a motor for this purpose. Don't know any of the reasons. Will see if I can find the video again.
Found it:
перемотка двигателей, AlexMos Simple BLGC
Very similar to rthe great Russian Arm Flight heads. At least the camera moves so. I wonder how long of lens can be used effectively?
New update from Laforet with answers to common questions. http://blog.vincentlaforet.com/2013/04/07/movi-update-answers-to-common-question/
My new thought on all of this is which inexpensive gopro solution will also work for the Blackmagic Pocket Cinema camera and how soon can someone market them as a ready to shoot solution!?
This could be attached to the rig ...
Zenmuse with Zeiss 24mm 1.8 lens
The real beauty of this device is that it is so small. Imagine the MöVi or a similar device on a shot of this kind (starting 1:45 min):
Soy Cuba is from 1964 but still a classic with extraordinary shots.The camera was handheld and passed from one operator to another or connected to the cablecam trollies ascending from street level, through the building and at the other side again on a cablecam and above the street. Thogether there were two flights with a cablecam system and the system was connected with a magnet to the trollies for fast coupling. I would use carabiners for higher saftey and together with my cablecam I can imagine to get something like this done. The stabilized third axis would also help on the cablecam to point the camera correctly and beeing stabilized like in the MöVi video.
Here is some additional information about the movie: http://www.rogerdeakins.com/forum2/viewtopic.php?f=2&t=850
There are different projects around worldwide for brushless technology, some of them are open source. I also develop a brushless gimbal of this kind as so I might be a little overexcited about it...
