    Driving 740 LEDs with variable intensity

    Sounds good, would you happen to have a name or a link?  8) All the best, Basil PS: I'm in Denmark

    Driving 740 LEDs with variable intensity

    hehehehe. Now, that's excactly how i'd describe my relationship with those  too ;) Thanks a lot for bringing the PICAXEs to my attention. It looks like they have all i need: A PWM out and a RTclock/LCD add on. Seems, providing i stick with PWM, all i need to worry about is the powersupply...

    Driving 740 LEDs with variable intensity

    For a dawn simulation i need to control all LEDs together, fortunately. I have been considering using current control, but i think PWM is easier to build. I'll only need one output, which will make wiring up the LEDs easier.  Are there advantages using current control instead of PWM? I have...

    Driving 740 LEDs with variable intensity

    Ehhh, no. Do you think i should? All the best, Basil

    Driving 740 LEDs with variable intensity

    Yes, i think i'll make series of six LEDs with a resistor on the tail, seems the easiest.  A resistor for each diode seems to me to be a lot of work. Now for a power-supply; i have been eyeing all those old computer power supplies i have. Stacking two of those would provide a nice stable 24V...

    Driving 740 LEDs with variable intensity

    Hi all, My sweet wife wants a "dawn simulator" the ligthsource is to be LEDs, 740 of them in all....... I've tried to discourage her, but she seems to believe i can do magic with electronics since i built her an amplifier/mixer for her computer stack. I have been pondering how to drive those...

    Voice activated switch used in noisy conditions

    Hi, I had a somewhat similar problem where a click from a plastic coupling were to stop a test. The test machine was located in a production hall. The solution was to rectify the signal from the microphone to get an "average noise level" the rectified signal was "stored" in a capacitor with a...
