Hey all, whats the best way to make fake car alarm blinking led? Source will be car's battery.
NE555/ circuit with 2 transistors/ 1 transistor cicuit (open base)? Ofcourse easiest way would be to use attiny, but that would be too dumb

Just an LED that blinks?

...a flashing LED. You can literally get LED's that flash all on their without any external circuitry, other than the resistor.

It'll be stable enough that you'd need an oscilloscope to measure any jitter, sure.

LM3909 circuit will draw less than a flashing LED.

... We have a questions that don't deserve their own thread. There is also an electronics general. There's like five current "wut is dis" threads. Did something happen over the last year? Did /diy/ get popular, or is it just the shock of coming back after a year long withdrawal?
