    Variable speed flashing led

    That sounds like the sort of thing I am trying to achieve XPTICAL, a circuit diagram would be great if you have the time. I had to bore into a block last week, and it had a recess in the side which meant that the cutting tool was exposed as the work revolved. As the tool was quite shiny I was...

    Variable speed flashing led

    Too much fuss is made over safety, I think we should remove all safety warnings and let nature sort things out :-). But I do appreciate the concern. I thought of synchronisation, but it would have to be triggered by the main shaft rotation and be adjustable to a degree so that the flash came...

    Variable speed flashing led

    George thank you very much for taking the time to do this for me, I will bookmark this page against the time when I can do something with it :-), at the moment I am running flat out, I have been busy all day finishing off a winch that we built for launching paragliders, we've used it with a...

    Variable speed flashing led

    The variable one sounds best George, thank you. I've just checked and my lathe does 13.6 revolutions per second, is that speed possible with a high intensity led, or would it be best to go for a slower speed and try for a match at a harmonic speed?

    Variable speed flashing led

    George, thanks for the reply. I want to use the circuit as a strobe light on my lathe so that it appears stationary and will allow me to better adjust the depth of boring bar.

    Variable speed flashing led

    I want to flash an led at a variable rate, between 3 and 8 times per second, and think that a 555 timer might do the job but I have no real idea about designing a circuit myself, although I am quite capable of building it if someone could draw me a circuit, or tell me where such a circuit could...
