Direction-Determining Device
Posted On Friday May 9 2008 @ 4:00 aBehind the motor are placed the battery rack with the batteries in it, which can serve as a simple direction-determining device. In most cases it can form comparatively strong disturbance at the back of the rotary ball of the gravitational field matter of the rotation part, and can make the gravitational field matter emit and scatter in the opposite direction of the motor shaft (from the center of the rotation part to the motor), and hence make the direction of the antigravitational acceleration the same as the front direction of the shaft.
The power is 1.5 v nickel-cadmium batteries (about four batteries, placed in the battery rack). The main switch is a small single-pole single-throw switch. An elastic ties the switch blade and the switch base together. A length of cotton thread is tied on a thick wire (in the shape of a reversed L) joined to the switch base. Pull up the switch blade from its base with the cotton thread.
Use a match to light the cotton thread. When the thread brakes, the switch blade is pulled down by the elastic, and the electric current is turned on. In this way we can reduce the shake of the little boat caused by the shake of the hand.
