I design Simple dream baby automatic sensor night light as Figure 1 since it cheap and easy to makes,The LEDs glow brightly just when in night or dark only.
This is simple hight power LED flashlight,we use 24 LEDs super bright for display and 3 AA batteries and resistor for limit current so cheaper.
This Op-amp LED flasher circuit , that interesting. By it will wink to alternate between LED the red and LED the green. This circuit can work with IC LM324, [...]
This is Xenon Strobe Light circuit, model continual use a tube Xenon at give many brightnesses. By can fine blink fast or slow get , with VR1. By have SCR…
We used the two LED flasher with transistors only. Today we come to experiment the 3 LED flasher circuit by 3 transistors astable multivibrator,
Imagine that your car is broken on the way home. The battery is damaged or has run out of power. At that time, very night. How to make the rear…
The small Christmas LED flasher circuit is small and easy and cheaper than other circuit. It suitable for beginner. there are IC1- CD4093 as main,and 9 LED
