   The mixte bike has a tail light now

     Oh boy I bet with an LDR per LED you could create a sort of chaotic gate generator. In fact think I think nonlinearcuits has done something similar with a few of their designs. Mmm I wish I knew anything about electronics.

     @mds2 oh the patterns are just a byproduct of the parts I'm using. I want the tail light to blink and to do that as simply as possible, I wired a bunch of self-blinking LEDs in series with some bright LEDs. The bright LEDs are bright enough to easily be seen out on the road and the blinking LEDs cause the bright ones and themselves to blink and they have a nice side effect of limiting their own current, so I don't need to deal with a special driver or resistors.

     They're not actually patterns. It's just that each blinking LED has a slightly different blink right then it's peers and after a period they end up all blinking kind of randomly. It looks like patterns though

     @MLE_online I don't understand what the patterns are for, but everything about this looks friggin awesome!

     So ... in synths, a gate is a voltage pulse of (mostly) 5-10V, with a duration of a few ms.
     They're used to initiate other events (percussion or envelopes for instance)
     Chaos circuits usually generate variations that are not random, but not entirely predictable. Their limits of activity are known but within those limits can't completely be predicted.
     A device that generates gate sequences based on a chaos circuit can produce patterns that sound rhythmic but with continual variation

     @botvolution what is a chaotic gate generator?

     To demonstrate:

     This is a module called Stochaos designed by Andrew Fitch (nonlinearcircuits.com), based on a 1980 US Patent.

     Here it's driving two envelope generators, which are controlling two voltage controlled amplifiers, each being fed different kinds of noise.

     (yes I can see all the dust. yes there's a bit of tape covering the LEDs, its because I didn't select the right value of resistors and they're too bright. Yes one of the LEDs is duff)
