EEVblog #493 - DIY Video Camera Dolly For Workbenches
« on: July 12, 2013, 09:31:13 AM »
Dave makes a DIY camera dolly system that mounts under his work bench.
It's not complete yet, it possibly needs a 2nd rail platform and better tripod mount, but otherwise works fairly well.

Put some grease on it already!

Try mounting the tripod using pipe clamps. You can probably 3D print some spacers to suit the different size tubes!

When you put a second rail on, mount the drawer runners the way they're meant to be used, and it'll be smoother and more stable, also far less likely to be broken accidentally.

A jib crane with a counterweight might have been a little easier to build.
Was it really supposed to do that?

Yes, yes, and yes.
I need some suitable angled aluminium and some suitable spacers first.

Yeah, an extra pair of bearings would make sense, then you attach a plate (wood, aluminium?) across the front of the two black angle pieces to eliminate the side-to-side wobble. As for holding the tripod, how about a pair of something like this? http://www.xump.com/science/Burette-Clamp-Single-Coated-Jaws.cfm
The screw thread on the rear of the jaws looks like it has potential for mounting through the centre of the plate between the angle irons.

EDIT: Something like this:

You'd have to hack up your tripod (maybe find an el-cheapo one), but if you reverse the way the leg is mounted, i.e. largest tube mounted to the angle bracket and the "foot" attached at the top, it would solve your up-down telescoping problem.   :-+

On the tripod.

Something like this, with the camera plate able to be mounted in vertical and horizontal positions.

Made one recently with a few lengths of steel tubing (mop handles I think) and a couple of weights from the local sports store. Less that $20 in materials.

I would at least try to use these.



I would even try to get the battery out of the camera and use external power supply to reduce the wobble.

Another great project for the future ?

mount the rail on the ceiling. have a stepper motor to roll it along the desk.
have a worm drive telescope arm that can lower / raise camera ..

now that would be fun.

The ceiling moves.

That can be solved (horizontal rail on vertical pipes poking through the ceiling tiles in a couple of places and affixed to the slab above.  A lot more work of course.

An excellent way to piss off the neighbours upstairs, too. :)
