Flickering LED's like a firefly effect?
"Hey guys, wondering if I could get your help with a project for my daughters school play.
The effect I want to do is a led sort of fire fly or even a flicker candle effect with about 100 led's. I would like to possibly have control over the amount of time they are off or at times just keep it on steady as a regular flicker effect.
The led's would all hang individually above the set, so any resistors would be at the top where you do not see them.
I would like this to be powered by a transformer, not battery and plug it in the wall.
So to have about a 100 or more random flickering little led's is the goal and executed in the most logical (and clean) way. I have seen long lengths of copper tape and then solder to that or whatever you think.
I know this is just a play, but woud mean a lot to my daughter. I can put it all together with a plan and a good source to get the various elements.
soooo the idea is have the led's suspended by the cable hanging down maybe 6' from above where I would have a 1 x 4 grid to hang everything from.
The led's would either have random flickers on a slow (hopefully) adjustable sequence. Out of 100 led's you would only want maybe 3, 4, 5 (who knows how many yet) on at one time. So just quick little flashes of pulsed light like the flicker candles do. So you would have little clusters of 2 or 3 leds hanging down and I would use black heat shrink to bind it up and the cable (22 guage?) would be black as well.
The other idea may be to just have a constant candle flicker effect to each "drop" and leave it at that. Would be great to know how to do both.
