Hi everyone, I'm Jerry. It's good to see this new forum coming out. I'm a long time builder, and I've 'played' with quite a few devices. (Most of the time there was an unrecognized, unaccounted-for force which prevented successful operation, but I learned as I went along). My primary focus involves what I call a Split Gyroscope. When the gyroscopical mass is split onto two counter rotating shafts, both sides will move in the same direction when the gyro is tipped, unlike the complex torquing of a regular gyroscope. All movements - horizontal or vertical - are forced, to conserve rotational radius' inertia. Horizontal movement: https://youtu.be/yzaJuyPpBcs?si=FN9iObTGMbjRgT8m Vertical movement, with a steering technique (out of synch rotors): https://youtu.be/a1m1In1q7jA?si=lOZ-QMjwgfMtJl0A Bottom kicks out further than the top, proving no reverse force: https://youtu.be/IA20vsHaeos?si=D8sR4iwRjEaTr-Hj This unit, which has since smoked, did deflect a swinging pendulum's swing angle, when momentarily pulsed at the high point of the swing, perpendicular to gravity's effect against the pendulum. All of this stuff has long since been open sourced into the Public Domain. -JV
