I looked in all deals topics, and nothing with "pegasus" in there. where can i find it?

@Vitaliy_Kiselev do you know if is there any chance of being able to buy just their 'front-and-back' camera head unit? I like the 'memory markings' on the pegasus :-)

the upper balance bracket

well, if i researched correctly, the pegasus is a steadycam-type of stabiliser.
But a gyroscope stab. is a different category...its active stab, for situations where the pegasus would never work (on a car, a boat, a plane or helicopter, a jib\crane, etc..) its for a different use that the pegasus style.

@gasosas

Yep, but people who make professional shooting in a boat, plane or helicopter won't be using proposed DIY solution.

@gasosas

HDDs are fuckingly bad gyros.
If you think that something will change and you'll soon see cheap and good gyroscope, you are wrong.

Hi @balazer Although it's a great idea, I did a lot of reading around this subject a while back, and if you use three gyros at right-angles to each other I think the three basically cancel each other out somehow.

I've had some success on my old mini-DV camcorder, using one gyro - but the vibration upset the camera a bit and it never worked properly after that. And of course tripods react in slightly weird ways when you move them around.

I guess the other idea might be to use a lot of inertia, perhaps by sticking some very long arms on the camera with weights at the ends. That way you make better use of inertia without needing huge weights. It would look very weird though! I think this is how archery stabilizers work.

You can get electronic gyros which is how r/c helicopters stabilize, and I think there are a few YouTube vids out there of people who've used that approach to build stable camera platforms. Way beyond my skills though.

There's one trick I've used occasionally, when you want a low angle: you turn the tripod upside-down and walk around with the camera upside-down, just above the floor. Then you flip the picture upright in editing. It's very simple and low-tech but can be good for low-angle tracking shots of pets etc.

@Mark_the_Harp, if you have two gyros spinning on the same axis in opposite directions, the rotational momentum is cancelled out. You need 3 gyros at right angles to provide stabilization on all 3 axes. The Kenyon stabilizers have two gyros mounted on a gimbal, which is good enough apparently, for reasons that I don't entirely understand.

I did build a simple stabilizer: basically a monopod that I made into an upside-down T with weights on the ends, kind of like a Glidecam HD without the gimbal. It helps somewhat. Even more than using its inertia, it helps a lot to prop it against my body. I think I will buy some kind of shoulder & body mount.

The electronic gyros for radio controlled helicopters don't use their inertia to physically stabilize the helicopter. They are simply input to a control system, giving it a constant directional reference. You can have a similar kind of active control stabilization for cameras: it's what we already have in lenses with stabilization. (I think they only need accelerometers, not gyros, but it's a similar idea)

In fact I've decided that I'm not particularly interested in dynamically balanced stabilizers or gyros at the moment. I don't like that look of floating. Actually it's the slow rolling motion that bothers me. It makes me seasick, like a boat. I want to maintain control over the camera's direction while getting rid of the high frequency, low magnitude shaking. I think that's best done with a combination of in-lens stabilization, a mount that braces against your body, and software stabilization. A bit of low frequency shaking is o.k. We see that all the time in TV and movies, and it's not a big deal.

guys, thanks a lot for the feedback, it's been tremendously usefull..i really thought the hard disk idea would work, but the 'not enough mass\speed' argument makes sense (if we're not talking about a tiny camera weight, at least)
i'd love to get one from kenlabs (or the blackbird, whenever it's ready..looks good on paper,right?) but for the eventual use i'd get from it, it's still not worthed for me, unfortunatlly.

i never saw one 'in the flesh'...is it noisy, really? i would never think so...

I've used the Kenyons before on boats, 2 units 90degree offset. Yes they are extremely noisy and limited by how much battery power/inverter you have access to. Think a screaming high pitched whine. They work excellent as long as you don't fight them.

I 've also used DIY Gyro's made from fast spinning Dremels mounted to a monopod under the camera. Works ok as long as you eliminate the vibrations by rubber mount isolation.
