Dyna-Flex PowerBall Tachometer Hack HELP !?! Is their anybody out their???? Answered
I'm looking for a way to Hack this Dyna-Flex PowerBall Tachometer ( Speedometer ) I wish to use this LCD device to Time ,register shutter speed,& motor speed for 16mm & 35mm Motion Picture Cameras. The Tachometer displayes RPM's, I need to know the exact speed of the camera, ie: 1800 RPM's = 24 fps ( frames per second )I'm not sure how this unit works ? Induction current ? The Dyna-Flex Gyro Ball has coils & a magnet that is incorporated in the Ball. The Tachometer will only register the RPM's if it is on top of the PowerBalls window, and not on the side of the ball.
This unit could be used for many other applications. Since it is the size of a Silver Dollar and uses little or no power, with the right pick up ( magnetic ? ) it could be of great technical use with other HACK projects.
