doh, I tried, and I'll try again, but i don't know why is syncing, if its because they are too close each other or...
Yeah, I'm not sure why that happens. It's really hard to prevent it when you're building on this scale. I have much larger versions of this idea which work fine, but I gave up trying to make the tiny ones work like they should.
it was staged, but in somehow after the first lap, they keep syncing
In the chained version, set the tmp and life of VIBR to staggered values. That way they will all get 'charged' and 'defused' at different times, if you time it right you can have constant SPRK output at all times. You'll have to do a little bit of maths to find the right values to use, though.
