Last modification get the desidered result: no more step shocks. No compromise with other stabilizing performances.
Now the only thing to improve is my ability to drive it, by intense practical usage and learning some job tricks.
On board camera: Panasonic HDC-TM900. The OIS is deactived to best show own swiffercam behaviour. More effective result is expected with OIS switched-on.
Videoclip to show my self-made device to shoot as camera-car. Very easy, intuitive and cheap in construction to achieve non professional result (vibrations due to the road surface are not absorbed)
Anyway the camcorder's O.I.S gives a pleasant effect in following car motion.
