Use the bottom circuit as the base.

From the top circuit, you’ll need that blue wire and the switch. Tack the blue wire onto the tip of the input just from the bottom circuit and wire it to the momentary switch. The black wire on the momentary switch can go to any ground point then, whether it be one of the sleeves of the in/out jacks, or the bottom right lug of the mute switch.

Can you condense that down to one paragraph and have it on my desk by 5?

 :P I kid.

Thanks for the link! I remember seeing that a couple years ago. Time to mine some info. Thank you!

From what I understand, your basic through zero flange is taking the dry signal of a flanger and slightly delaying it so the modulating flange’d signal gets to slower delay speeds than the delay’d dry signal.

So what happens if you split the signal into three - one dry signal, and two then paths into flanger circuitry, but have the flanger driven by bipolar LFO’s? So as one path increases in delay time, the other decreases. Once the signals are summed, would something interesting happen, or would there be a lot of cancelation?

What’s the part number you’re looking for?

I’d think the synth stuff would use a bipolar supply? At least the MFOS one does.

The 8 step kajjiger puts out 0-5V. I think it’d be easy enough to strap and LDR onto the delay pot, then have an LED light up with the 8 step CV out.

Do you mean you want to use it like an LFO? Or to tap in a tempo and have it set the delay time? One is infinitely more easy than the other!

Saw Jurassic World 2.

I thought the first Jurassic World was good, probably mostly nostalgia.

#2 went off the rails, and I can’t figure out if it’s in a good way or a bad way. Spoilers: Did they really just set up a where dinosaurs roam free humans can be cloned? Living dinosaurs requires some suspension of belief, but this seems to be going in a far more ludicrous direction. I was also not expecting to feel far More emotionally connected  a dinosaur than any of the actual characters.

In my barren brain I thought this is how it would be wired! Maybe I'm learning something? Thanks Ham!

I found the key to understanding switch wiring is the understand how the switch works AND what you want to accomplish. A picture helps, but putting your DMM on connectivity (or resistance) and measuring between pins of switches as you change state really helps. Combine that with knowing what you want to do and visualizing what the circuit looks like with the switch being a simple connection (removing all the bits that are not in the circuit when the switch is in one state), you can tackle and switching problem!

Drawing it out certainly helps too, then tracing your switch in different colors That the signal will take when the switch is in different positions to visualize it.

This is from Google, but is similar. The only difference is the center lug of your switch is connecting to one side where the cap goes on the PCB, and in the photo, where all of the caps connect together at ground, you’re connecting them all together to the other side of where the cap goes on the PCB.

Your rotary will have the 2 poles in the center and then 12 pigs around the outside. Each pole has a corresponding 6 lugs around the outside, that as you turn the shaft, get connected. This picture should help you out.

For your application, you only need one of the poles. So you’d send a wire from one side of the cap on the board to the center pole you want to use. Attach one leg of each cap to each of the outer lugs. The other end of each cap get soldered together and then all run back to the other pad for the cap on the board.

You can get thrifty and mount the caps across to the other side of the switch, then short all of the unused side of the rotary together and run one wire back from there.

Gat dang that’s a beaut. Goldtop and P90’s, a classic combo. Lovely.
