Re: Some questions of my DIY project

Do you know about kinematic design ? It can be very helpful for this kind of thing.

The basic idea is that any object can move in six directions: translation in X Y or Z, and rotation around the X Y and Z axes. (This applies to camera shake and stabilisation among other things).

The principle is to apply only enough constraints to prevent those of the six movements you don't want. This makes it much easier to make something that is accurate but simple. The best introduction I know is in a little old book by Braddick called "Mechanical Design of Laboratory Apparatus". If you Google this you will find a PDF to download, or you can buy a used copy for a few dollars on Amazon.

(Recently the people who design robots have made this subject very heavy and mathematical.)

One possibility for the legs would be to buy an old tripod on eBay and cannibalize it.
