John Jorsett writes "Always wanted to film one of those cool 'walking' sequences, where the camera stays rock-steady as you trudge along? Well, so did Johnny Chung Lee, except he didn't want to lay out major cash for a professional Steadicam rig, so he built his own for $14. He further claims you can do it in about 20 minutes if you know what you're doing. What more could a cheap, impatient Spielberg wannabe ask for?"

the best solution I have ever seen was a monopod modified to have a plastic coated weight at the bottom, it collapses into something that can be carried and is much easier to control plus costs less and weighs less.
although it is still NOTHING like a real steadicam.. wearing that vest with the spring arm and rest of the gear coupled with a REAL 5 inch LCD monitor mounted on the weight plate... a trained operater can almost run at full speed without motion in the camera... the home brew units can not do anytihng like that.
Plus I find the vest unit to be more comfortable and can shoot for much longer... having your body support the weight compared to the home built that requires your arms to support everything is significant!

Simple: It's not a tripod, and it has no wheels.
At best, you could call it a monopod, but even then, it's meant to be carried, it doesn't rest on the ground. So I guess it's a nonopod.
What it really is is a stick with a weight attached. The weight steadies the camera from sudden jerks, simply due to it's own inertia. It still relies on the camera guy to have a fairly steady hand, this just "takes the edge off" of the shakiness, so to speak.

Just receantly the department I now work at got slashdotted (the meteor impact simulator). It was on a Sunblade with deceant stats, and the load average shot to 98 within a couple minutes. We finally offloaded it to a brand new (as in got it a week ago) Sun blade doing nothing but hosting that simulator and it was STILL at about a 25 load average, though it stayed up and serving.
Here we were on a much improved network (dual gig backbone to 3x OC-3s as opposed to the 10mb to 1x DS-3 back in the newspaper days), servers an couple orders of magnitude more powerful, and one dedidacted to serving, and yet got hit much harder. The big difference was the content was dynamic. The network wasn't even strained (it was all text anyhow) but the server was being asked to do a ton.
In this case it looks all static, so I'm guessing it's probably either the connection, or general load on the system. After all, this isn't his server, it's a departmental server, and probably one with a lot of users.

All he's doing is adding a weight to make it hard for you to move your hands. And you can tell he's having a rough time with it as many of the shots are crooked. It's not properly weighted on the other side so he has to push down with one hand, up with the other and maintain a horizontal position throughout the shot. And he can't do it so the image is tilted most of the time. He'd have a chance of keeping the horizontal straight if he made a "T" instead of an "L"
This is why real steady cams are mounted on the chest like a snare drum. The springs/hydrolics take care of the vertical bounce and the mounting position balances the horizontal. The operator would have to bend over to one side to tilt the shot. If you want to get an "up" shot you bend over, point the camera up and walk backwards.
This is also why most movies move the camera around a lot. Besides it adding to the scene. It's actually easier to keep a steady path of movement than to hold a camera still.

No (Score:4, Interesting)
Keeping a camera still is trivial if you use a tripod. A steady path of movement gets expensive (in crew and equipment) quickly. The steadier you want it the more it costs. Even getting a non-jerky pan multiplies the cost of a tripod time ten.
The reason that movies move the camera a lot is because that is usually what tells the story best.

That same background (Score:5, Interesting)
In my old school marching band was just walking up and down the street. In my new school it was walking up and down the street I think once or twice but the rest of the time it was doing half time shows and competitions with formations and whatnot which was really cool. I had to learn how to basically run and play at the same time while keeping the instrument level.
Kind of like running with a video camera and not bouncing it around.
A lot of people don't get the practical applications of things like that because they're too concerned with not being "geeky" and just plain short sighted.
And this is why schools tend to cut music programs while the athletic department gets gobs of money.

Look into something more sophisticated... (Score:5, Interesting)
I've built one of these too, and all things being equal, I think you would be better off spending $120 to get one of the Steady cam clones. True, he has some cool shots on his page but those are not nearly as easy as he makes it out to be. Maybe I am just clumsy.
When I walk forward my system wants to behave like a pendulum causing the camera to rock forward and back around the horizonal fulcrum. If things aren't perfectly balanced it is very difficult to keep the cameras tilt at a given attitude. Your left hand (if you were the author in the photo on the page) will not be able to keep the attitude without pendulum style oscillation. It's also difficult to make the camera turn around the camera of the horiontal bar and the fact that the rotational inertia of the person-pipe-camera system is not appropriate for turning around the camera.
Beyond those basic problems: it's also hard to hold on to and I tend to smack into door frames and innocent bystanders with the horizonal pipe.
One of the key parts to a steady cam rig is a gimbal joint that isolates tilt/tip motions of your hand from the "mass" that has the camera. Without this isolation it's really hard to get good shots without Zen master balance or just being lucky.
If anyone out there wants to make a Steady-cam like rig, I suggest they copy something like the Flowpod [varizoom.com]. Note the gimbal connecting the handle to the body of the device.

I can kinda understand where you're coming from, but honestly, it kind of erks me. And I've started seeing quite a few of these in this article. This guy spent $14 and maybe thirty minutes to an hour learning how to get the thing to work well, and yet for some reason paying nine times as much and also taking some time to learn to use it seems like a better idea?
Maybe if you can afford it. I'm a poor college kid who has several expensive hobbies. What you are saying is, I would be better off taking my car to a car audio store and having them install my stereo system for me, at the cost of $300 or so. That or I can do it myself, take a few days longer, for $40, and maybe not look quite as good. In my case I thought it was pretty damned close, and even though it took me a lot longer, I got the satisfaction of doing it myself. Thats the key thing here, I think, that most people miss.
He improvised, saved some money, and made a pretty good gadget himself. Decent accomplishment even if it isn't as good as something that costs nine times more. And thats just the cheap one, right?
Now, as far as him trying to make money off of it, I might see where you could complain about that. I think I would in his case too, but I don't think that would bother me as much.

I mean watch a football game. There are tons of shoulder mounted shots that are quite good. As with anything, the skill of the operator is a large factor, but you don't need a stedicam to get a deceant shot, just a solid unit on your shoulder. Probably better than this, since this unit is going to want to act like a pendulum when faced with motion.

Re:Not quite the same thing. (Score:5, Insightful)
That's not at all what he's doing. The key to the steadycam is that the center of gravity of the apparatus is inside the handle (which is why you need a weight on the end of a pole to counterbalance the camcorder). This means that as you yank the camcorder around by the handle, *only* the position of the camera changes, not the orientation. This removes the much of the "jerkiness" of handheld shots that otherwise screams "low-budget amateur video!" Even without a gimbal mount for the handle, this device can still reduce handheld video jerkiness by a significant amount. Of course a gimbal-mounted handle would be better and would allow easier smooth panning, but it would be hard to do for $14 with commonly-available parts and easy assembly.

Granted this is significantly cheaper to make than these products, but from my experience anything that is handheld doesn't work as well as the bodyrigs. Personally, I'd rather just do it by hand alone.

I saw a documentary about Garrett Brown, and it showed his various prototype stages. The original one looked exactly like this - a length of pipe. The second one was more like a pantograph to try to keep the camera level. Then he added the seperate handle connected to the upright portion wih a gimbal. The rest of the development was on the counter-balance arm and the vest. All of this was necessary because Brown was building these for 35mm film cameras.
If you're looking to improve this design, the things I'd look at are: a gimbal, so allow the operator to hold the unit more comfortably and lightly, and avoid transferring hand motion to the camera; a sliding mount at the top, to allow the camera's balance to be shifted forward and back to tilt up or down.
The Steadycam JR Lite [steadicam.com] is a great one to look at. It was designed by the great Frogdesign studio (the NeXT cube). The camera sits on top of a slide, and right on top of the gimbal and handle. The arm is divided into two parts at a 90 degree angle, connected to the slide at 45 degrees. And the whole thing folds up. It's a wonderfully slick design - and obscenely overpriced [bhphotovideo.com].
