A timer circuit 555
The number of coils for each coil consists of 200 to 300 turns around a plastic or wooden tube.
How the device works.
The device works by magnetic induction generated by the two coils alternately with each other. Where the magnetic field formed in the coils affects the magnet that is in the middle, while the timer 555 generates pulses simultaneously and here comes the role of AISI cd4017, as it distributes the pulses in a sequential manner over the amplifier, which in turn cuts the DC current to produce intermittent vibrations from this piece so that the two coils work alternately with each other. ,
