SplitFlapKinematoscope

Açıklama

https://youtu.be/gd3dIFpSpE8Split flap clocks have been in use for some time in alarm clocks and in train stations.The mechanisme is relatively simple. Moreover, if the rotationspeed is increased, it acts as a kinematoscope (zoetrope like result)(thanks Kongorilla). The movie is quick and dirty because I did not have the patience to make nice series of drawings. I'm sure you can do better :-).The motor is a popular mini geared motor. The battery voltage should be choosen below the motor voltage, to reduce the rotation speed. The stop bar on top can be rotated to achieve a good synchronisation. The wheel is printed twice. At one side an M3 screw is inserted and fastened with a nut. The other side recieves the motor shaft. The two halves are connected with two M3 screws. The flaps are inserted by bending them a little.
