Right after “no editing whatsoever”, the “shaky camera” is the bane of YouTube viewers the world over. [David] came up with a nice solution to the problem of shaky cameras that uses gyroscopes to even out the bumps of making a great movie.
Most cameras attached to moving frames – from the zip-line cameras at NFL games to police helicopters and aerial reconnaissance drones – have some sort of gyroscopic stabilization. Even though gyroscopic stabilization has been around for more than 60 years, the designs haven’t changed that much. [David] dug up a few patents dating from the 50s and set to work replicating the design.
[David] bought a pair of [Glenn Turner]‘s fabulously heavy and expensive-looking powered gyroscopes and began bolting them onto a piece of sheet metal. Per the 1950 patent, the gyroscopes were mounted 90 degrees apart and bolted onto the camera.
From the video demo (after the break), there’s a marked difference between filming a stroll though a parking lot with the gyros on and gyros off. While the pair of motor driven gyroscopes look a little ungainly and are a bit too loud for our tastes, the solution is much less expensive than the $1600 professional gyro [David] based his build on.
