Bike tail LED light flashing
Lightings
This is a bike tail LED light flashing as the planet Bike Blinky Safety. When we use the bicycle(normal bike) at night. we used IC1 IC555 Oscillator signal is output to a lot LED super bright. Present roads in good condition than the former roads, the traffic is convenient. But often car ran high speeds. When we use the bicycle(normal bike) at night. Although we will attach the reflective sheeting at the end of the bicycle. But it could be dangerous. We should attack the planet Bike Blinky Safety at the end of our bike would be better. Operation of …
Siren light from running light
Lightings
The siren light use that general use motor help in the whirl lamp or refect go to around, which weigh very and when be usable go to for a long time will cause the wearing out. but if we modify light running pretend siren make get siren that weigh light and can be usable for a long time go up. The work of the circuit will divide the work goes out to are 3 the part, be origin frequency part will compose IC1 555 numbers will perform frequency origin. which fix get with the value of R1, R2 and C1. …
Light turning bike using IC LM3909
Basic Circuits
Usual already a bicycle has will no Light turning. If want to turn a car may be born dangerous can go up. Because of a car that drive to follow come to don’t know that turn thus. We should enhance the safety gives with one self with building light turning bike circuit this upward. The work of the circuit be in usual time switch S1 will stay in a position OFF. If the circuit will turn to the right move switch S1 go to a position Right have power supply 1.5V, go to at IC1 which be IC1 work oscillator …
