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 super 12v light flasher circuit. It is high power out load(lamp 12V). I used the Transistor 2SC1061 or H1061 or TIP41 for drive lamp light 12V 20W.
This is a circuit that features a running pace with a changing voice, the tiny microphone. For a frivolous fun.
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,
