Help with building a "random" pedal.

Say I mix two outputs from the 4016 together again, is there an audible click when the 4016 changes between the outputs?

Yes, this is definitely a possibility, but with care and planning, it is completely avoidable.  The most likely scenario woudl be having two signals biased at different points.  The 4016 itself won't pop, and if it does, the 4066 won't.

the regulator is only going to lower a higher voltage down to 9v though. thats not what i'm talking about at all. i'm saying that if i run it off a 9v battery and the battery starts to wear out and goes to like 8.3v or whatever then the noise will stop. and if i try and run it with another circuit like a delay or something off the same battery, it will not work at all. so adding it to this S&H will not work until that is figured out. i tried a few things but no success.



hey caress hope the move went well. my last one was a borderline nightmare. once everything was said and done i’m so happy i did it though. i have never been able to turn my amp up above 4, but now i can crank it 24 hours a day. its a whole new world.

i meant a dc jack.  i hate them too and only use them when i have to...

The regulator is to fix this problem, not the problem of a battery getting low.  There are plenty of circuits that will stop working on a battery that starts to go.   It would isolate the white noise circuit  from the other circuit. Did you try that and it didn't work?  There are plenty of other white noise designs that will certainly work with other circuits, if you have no success.

only 1 out of like 5 different brands of battery's would work and if that battery was used for lets say an hour it would die. sometimes less, i didn't time it though. but that battery would work fine in everything else i tried it in. i did try different filter and decoupling caps but i don't know of any other way to isolate it aside from giving it its own supply which i didn't want to do with what i was messing with at the time.
