Hey gang I'm in need of a circuit that will flash a array of LEDs at =
14hz. The LED array isn't a problem to build but the flasher circuit has =
got me scratching my head. I need the flasher to flash the LEDS so that =
the pulses will have a rise time from start of pulse to peak of pulse of =
10 microseconds or less. I've thought about a 555 chip but it seemed =
like it wouldn't be that stable.
