Homemade Clock

The principle of operation is gear rotation. In a mechanical clock,the main moving parts include the springgears, balance wheel, and hands.The spring is responsible for storingenergy, which is released to drive the gears. The gears transmit energysmoothly through a series of transmissions and also control themovement of the hands. The balance wheel stabilizes the passage oftime by oscillating.The entire mechanism works together to make thehands move at a certain rate to show the exact time.

Automatic Pitching Machine

The principle of operation is wheel chafing. Automatic Pitching Machine is when the ball from the slide into thetwo balls between the use of two high-speed rotation, the directionof rotation of the opposite direction of the wheel, and the spacebetween the wheel is slightly smaller than the diameter of the ballthe wheel and the ball will produce friction between the ball, theball will be quickly spun out!

Conductor Detection Dinosaur

The principle of operation is insulation resistance test. Conductor material is conducive to the propagation of electric currentplace substance in the mouth of dinosaurs, press the upper part of themouth, the dinosaur eye lights bright is a conductor, or is an insulator.Common conductors in life are metal, graphite, the human body, theearth, acid and alkali salt solutions.Conductivity reasons: conductors in a large number of free-movingelectric charge.

Voice-activated Fan

The principle of operation is sound control. When the microphone detects the sound signal, the sound controlmodule outputs the voltage, which controls the motor to rotate fora few seconds and then stops, realising the use of sound to controlthe fan running rotation. Sensor is a detection device that receivesthe detected information and turns the information into electricalsignals according to a certain law to meet other needs.

Mechanical Car

The principle of operation is mechanical motive force. Rebound relies on the rebound tooth box to accumulate elasticpotential energy and pull back, and when released the accumulatedelastic potential energy is converted into kinetic energy to make thecar run forward. As the car moves forward, the path of motion of theeccentric wheel, causes the shovel to oscillate up and down.
