Hi all. Maybe the brilliant minds here can help me with, well,,,, design. Picture 2 vertical cones, one upside down, joined at their tips. Actually there is a small sphere between the tips and the tips are cut off. There is a shaft going through top to bottom. The cones always rotate around the shaft. The shaft stays straight vertical always. The swivel point is the center of the sphere. As the top cone tilts, the bottom cone goes opposite acting as a counter-balance so the whole unit does not vibrate. The cones tilt stops when the inside of the cone side wall hits the shaft. Because the cone-cam is tilted and spinning around the shaft, it resembles a doppler effect. It's spinning, circular diameter path is much more than when the cone is not tilted. So far, ez enough. The tricky part and challenge is to control the amount of cone-cam tilt with a joystick. At least I haven't figured it out yet. Could be worth mega$ some year.
