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, [...]
We used the two LED flasher with transistors only. Today we come to experiment the 3 LED flasher circuit by 3 transistors astable multivibrator,
This is a fast blinking LED bike light circuit For safety when the bike at night. We use two-NPN-PNP transistor oscillator circuit and RC circuit only show on 4 LEDs…
If you want one A lamp flasher circuit using transistors that flashing for general to use. I have many ways, But today you see this three of the lamp flasher circuits.[...]
