[Derek] likes to get a little bit of drivers-eye footage when racing his motorcycle, but there’s an inherent problem with mounting a camera to a moving and tilting platform. When he leans into turns, the camera can’t keep the horizon level. Cinematography and electronics go well together. so [Derek] built a horizon-stabilized camera mount for motorcycle videography.
The build was inspired by footage shot from [Valentino Rossi's bike in 2010. Of course the professional model costs a small fortune, but [Derek] managed to make his own out of 3D printed parts and a hobby servo.
Based on the Contour Roam camera, [Derek] had a pair of gears printed at Shapeways to fit over the camera and attach to a servo. The electronics are an ATMega32 with a L3G4200D gyroscope. When the ‘micro detects a change in the gyroscope it rotates the servo in the opposite direction, keeping the horizon in the video level.
It’s a very cool build, and judging from the action videos after the break, makes for awesome track footage.
