Project: DIY Steadicam for under £100

Anyone care to guess what it's going to be?

So we have:

2 Universal Joints
1 Giottos Quick Release slide plate
8 Abec7 Bearings
50 50mm Washers

On order:
1 Pistol Grip
1x 1000mm x 30mm x 5mm aluminium flatbar

To order:
Tapping tool for 1/4 UNC 20TPI
Bolts
Nuts
Maybe some other bits and bobs as they become necessary...

I still don't understand how it counteracts the unsteady motion of a arm holding a heavy object...

I believe the fundamental principals behind the steadicam are the following:

1. effecting the cameras 'Moment of Inertia' or in layman terms reducing it's ease of rotation about the cameras axis of rotation.

and

2. spreading the mass of the unit across a larger area and subsequently isolating it (through a low friction joint) causing a damping effect between the operators small movements and the camera.

The smoothness of motion is gained through the operators ability to self dampen their 'bounce' and the rig takes care of the rotational damping by shifting the axis of rotation away from the camera and then reducing the pendulum effect of the hanging arm by 'almost' balancing the axis around the grip. Almost because you still want the camera to hang vertical but you also don't want it to pendulum out when going around corners or changing direction.
 
Years agao I made a very simple steadicam type device using copper piping and a weight lifting weight, it was a simple 't' shape construction with the weight held below the camera and a bar out at a right angle . You held the end of the bar and the joint area.

Once you had got used to the way of holding it, it was incredibly effective, and it only cost me about £20 in materials!!!

Similar in theory to this one? My main concern is that it doesn't end up looking too 'rangi' i.e. has some aesthetic appeal.

Even more basic that that, it was literally just three lengths (about 12 inches each iirc), a T union. A modified end cap on one length, with a padded dished washed and a thread to attach and hold the video camera in place.

Similar on one of the other lengths to hold the weight and then the third length coming out of the t section and 90 degrees for you to hold on to.

Sort of like this.

It didn't look particularly pretty but worked really well. Yours looks much much nicer!

Well a little further down the road now - switched handles to an old barbell handle because the skateboard bearing wasn't playing nice with the other handle I purchased.

Having a mare of a time figuring the balance out and also locking the bearing in so it doesn't shift in the handle.
