Re: Turntable Stroboscope
I did not try to measure the persistance of the white LEDs I used in my strobe project. What I do know is that with the circuit I gave I get a _very_ clear stationary pattern on the strobe markings of the spindle of an old floppy disk drive (which is what I originally made it for). Even if the persistance of the LED keeps it on for longer than 1/16th of the time it still goes off for sufficiently long to work.
