Profession gyroscopic stabilization systems for video cameras can get quite expensive. So, what’s a tinkerer to do? The DIY route, and that’s exactly what [David Prutchi] did.
Also as part of the project, I came across the professional-grade (and professionally priced, starting at $1,600) gyroscopic camera stabilizers made by Kenyon Laboratories. These devices don’t seem to have changed much since Kenyon’s founder filed the following two patents in the 50′s: US2811042, US2570130.
