The 1.5v led flashlight circuit which also use single AA 1.5V battery. But few parts. Such as we use one transistor only. And all other parts of 5 pcs only
This is first mini emergency light of my son. It is very small, use LED display when power outage,use transistor instead relay use AA battery charger.
This is many LED flasher circuit and with PCB layout using transistors astable multi vibrator as low frequency oscillator below more...
We will add beauty to CAR brake light circuit. With a display of 14 LEDs, visible clearly, for safety and beautiful. The installation format can fix by oneself as you like it.
When we use the bicycle(normal bike) at night. we used IC1 IC555 Oscillator signal is output to a lot LED super bright.
The siren light uses 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 weighs light and can be usable for a long time go up. How it works 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, …
