One led flasher with 2SC1815

This circuit is a simple circuit using only capacitor C1.Resistors R1 frequency generator to Q1.Which acts like a switch.then used Q2 to be the current increase.
Operation of this circuit from capacitor C1 through R2 and LED1. Until the voltage drop at C1 increases,Q1 to the value that work.
As a result, the current Q1. The current through pin E and C stand to cooperate with the Q2 Q2 B’s conduct as a result, a current flows through LED1.While C1 is discharged through R1 to a period of time.When C1 discharge out there would be no pressure to bias the leg B of Q1. The Q1 to stop working, Q2 will stop working.LED1 will turn off and capacitor C1 will start again.The Q1, Q2 LED1 light work, where work is of such and so on.

Very simple LED Flashing with sound

If we wasp one size miniature serial loudspeaker (8 ohm speaker) suits. Flashing LED number FRL – 4403 which be mourn shine that can can blink. By must not use other equipment help. unless , power supply gives with it only. Already will hear the sound goes out a loudspeaker in the rhythm that it works with.

Single LED GATE Flasher by 4011

From this circuit : Easy Lamp Flasher by IC 4011 I apply to new stye display with a Single LED, by I use cool digital IC , GATE Flasher IC-4011 quad nand gate.
so the Flashing output frequency = 1Hz. The IC 4011 ‘s Input pin 1 use for Control LED ON or Flasher.
Logic = Low (LED ON) , Logic Hi = LED Flasher. I like this circuit because it is easy to make.
Detail more, Please read in this image circuit. and you can see the next circuit of Two LED Flasher
