    Fasteddy,


    So if there are only grey and white wires, is there a way to get inside to connect a wire to the trigger pin?

    If you want the style with trigger and programmable pic, I could trade. I have some I didn't wire up. Just seems like a shame to open the sealed ones.

    Not that I know of and would be a lot of work because you would have to remove the covering which would then compromise the water proofness.
    Give them a go and see if they will still be suitable for your needs

    Skunberg,


    I tested the strobes tonight and think that they will work as long as there are plenty of other lights running at the same time and people don't have to "just" focus on the strobes.


    Thanks for the offer, but I am going to go with the ones I have this year.

    I think you'll be happy with them.

    I have an idea on how to get these strobes to turn on in a randomised state, but don't have any units to test.

    If someone wants to send me a string to play with, I'm happy to see what I can come up with.

    Popped my strobes in the mail this afternoon. Should be there next week :)

    Cool. Hopefully what I have in mind works.

    My initial testing of the strobe strings has been fruitful.

    By turning them on at around 2.3V, they will start randomising but not be visible.

    Snapping the voltage between 2.3V and 5V effectively turns the LEDs off and on.

    Because the supply voltage doesn't drop to zero, the randomising function doesn't restart each time.

    So, would most people have run these strobes from a DC controller output (on/off only) normally?

    I'd run from a dc controller yes, but if that channel is off, would there be no voltage down the line?
    How would we control to turn them off and on via a controller?

    My idea is for a small PCB that takes 5V from your main power supply and a channel input from your DC controller.

    It would then have an output that provides the switched voltage to the strobe string.

    When the channel is off, the output to the string would be 2.3V and when the channel is on, the output to the string would be 5V.

    The current draw for the 50 node string was hard to measure reliably, but seems to be approx 2 Amps worst case.

    Once the strobes are randomised the average current draw drops considerably.
     
    Fing and djgra79 like this.

    What's the interest from ACL members for a PCB to do this function?

    My guess is that I could sell them for $10 each. They'd be supplied fully built.

    Postage via a 500g red bag is around $9 but more than one board fits in a bag.

    I'm interested!! I'd probably take 2 at that price, thanks David :)

    I've created a new thread for interest in the boards.
