Design And Construction Of A Bicycle Guard

ABSTRACT

This work is on a bicycle guard which is an anti-theft device for bicycles which is inexpensive and can be constructed easily using a few components.

At the heart of the circuit is a wheel rotation detector, realized using a DC micro motor. For the purpose, you can use the micro-motor (spindle motor) of a discarded local CD deck mechanism. Power supply switch S1 should be kept ‘on’ when you are using this bicycle guard. When it is flipped towards ‘on’ position, the circuit gets power from the miniature 12V battery. Now LED1 lights up and resistor R4 limits the LED current. Next, the monostable built around IC1, which is CMOS version of timer LM555, is powered through a low-current, fixed-voltage regulator IC2 (78L05).
