Hello, I want to build a 1 led flasher NOT using a 555 or 556. I need it to flash about every half second or so. I want the least components possable.

HarveyH42 said:They make LEDs with the flash circuit built in, and its usually about 2 Hz... half a second per flash, can't get less parts then that.
wmmullaney said:OK, thanks. I DON't want a micocontroller. How do i generate a 2 htz signal?

1 Transistor, 1 Capacitor, 2 Resistors
What's wrong with an LED with a built in flash circuit?Thanks, but I just found a 4 part flasher. (see Will This Schematic Work?)
