Hi Colin,
Rick here from Miami Florida.
I have a question that maybe you can help. I need to make a ckt. to strobe 1 or 2 Ultra bright large L.E.D.'s. from radio shack. I need to have it adjustable from 800 Hz to 4000 Hz. I think that with a 50% duty cycle I can freeze what I am trying to watch. (an R/C airplane prop)
Can you suggest some values. for the variable resistor, and capacitor values?
I need to be able to freeze the prop outdoors, so I may have to add 2, 3, or 4 Ultra bright L.E.D.'s. to the output of the 555 timer. can it handle 100 - 120 Ma?
I will be powering the device with a 1200 mah 11.1 volt LiPo battery.
Thanks...
