LED Stroboscope

This circuit can be improved a bit by using a more stable STROBE RATE oscillator or by using a regulator to power the oscillator and associated logic. If you do this you should switch to 74HC class devices.

Xenon Strobe Light 110V by SCR

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 perform formed control the work and this circuit uses the fire AC 110 Volt or AC 220 Volt. But must use a pot transforms the sky decrease electricity pressure lower. The detail is other , see in the circuit.

PWM Driven Safety Strobe by UC3842 – TL3842

You’ve seen them when you’re driving. Mailmen use them, snow plows have them. This is a schematic of the circuit inside.This was taken from a popular unit available at NAPA auto parts stores. It’s amazing how simple it is for a PWM circuit.
It uses a UC3842 (here a TL3842 clone) pulse width modulator to regulate the charge on the main storage capacitor. In this respect is similar to a computer power supply. It has an interesting Zener booster circuit using an NPN transistor, shown on the left of the drawing. This keeps the supply voltage at or below 15V at all times. One great feature that this affords is a great variety of input voltages. It s rated at 12-80V.
