I'm new here and I was really hoping to find some help here. I am looking to light up an AMT/ERTL Star Trek U.S.S Enterprise from the movie Star Trek The Motion Picture and I think I've got the basic interior lighting, windows, etc. down but I really don't know how to create the navigation strobes with the 555. What components will I need? I'm working based on 9V if possible.
The 2 transistor led flasher should do the job for the navigation lights and there are plenty of schematics for led followers etc. if you want other effects.
The frequency is fixed at ~1.15Hz with a variable pulse width of 30ms to 840ms, which can be reversed (RV1) for 840ms pulse width and 30ms off time.
Since the LED on-time is just ~1/28 (at shortest pulse width) of a complete cycle you might use a current limiting resistor of 180Ω for a brighter flash without damaging the LED.
