My build progress

Gotta love those quick little sideprojects which should take no time at all, right? Just follow the datasheet, quick adventure, in and out.

Anyway, Electric Druid Digidelay with tap tempo and voltage-controlled everything should see daylight soon…

I have no idea why a delay would need 10 jacks and 10 knobs but I love it.

cool nice to see more stuff from you ! still digging the evil eyes …

looks great , not sure how far along you are , I should have said something when I first saw your pictures . but you might want to think about adding a 1/2" strip to the side panels between your rails . with the back set it is harder to get to the jacks / knobs on the ends . the spacer makes it a little easier . I built my last cabs with spacers and it makes it much easier than my original design .


with / without , you may loose a little rack space but it makes getting to knobs / jacks much easier .

I’m sure there is some correlation between the number of panel components and the time taken :slight_smile:

I would be interested in hearing how this turns out, as you have produced another feature-rich module.

Love this!!!

Would be keen to build one of these myself

Finally got to testing this, it is excellent! Worked first try, makes playing the instrument sound much better. Even works well with the VCDO with low rise/fall times, or long rise/rise fall times if you want to get a neat stepping effect.

It also works with audio signals, but only with small rise/fall times, but the effect is a really interesting filtering/octave lowering effect that makes a cool upright bass sound, very thick.

Seriously encourage other stripboarders to try this one! It is getting a permanent home in my box.

@jessecakeindustries great job!

@BlackDeath fat noodle, really cool.

What module are you chatting about, im confused?

Oh right! I was replying to my own earlier post. It’s this portamento module: Verified Stripboard Layouts! - #422 by jessecakeindustries

I was hoping the demo would demonstrate the “bendiness” in the sound.

What’s better than a toggle switch? 36 toggle switches!


This is a trigger sequencer I’ve finally finished after many months of trial and error. It was a bit of a nightmare to build, but to my continual surprise it does exactly what I wanted it to, which is the nice thing about making your own modules.

Clocking channel 1 syncs all 4 channels, but you can clock the other 3 individually or even clock one channel from the output of another which allows all sorts of rhythmic joy. The last toggle for each channel flips between 6 and 8 steps which is good enough for the time signatures I tend to use.
I can’t see many wanting to spend time building this exact module, but as I was inspired by seeing the builds of others, it’s always good to share your ideas.

Love the switches!!

I had a similar project with lots of LEDs, with SN74HC595 chips for two groups of 16 lights but it ended up flickering a lot when the LEDs would change. Wondering if you came across this issue or know why it might happen?

Thanks! I considered 16 steps but I couldn’t face the soldering and loss of panel space. I used 4 x CD4017 decade counters rather than shift registers, so I’ve not tried that approach. I had some issues with the counter timings on the 4017’s causing double-triggers but I fixed those with some questionable circuitry kludges. Your issue may be one for some of the Greater Forum Wizards.

Are you correctly pulling the latch pin, shifting out all data, and setting the latch again? Maybe post your code?

Protos have some issues but easy fixes (lol, I used BC547’s in the schem, and used an SMD footprint so it netlisted the pads incorrectly… lesson learned!)

Works lovely now!

I was getting surprisingly inaccurate voltage from a voltage reference once and it turned out…

Oh, you’ve done that too?

Building 100 oscillators sometimes gives you ideas…

And sometimes those ideas need refinement…

Nice! Do you apply any attenuation to the input signals to prevent their sum from overloading the output?

That’s basically the “refinement”
