This looks really good! I've always wondered if the the decoupling caps just before the individual photocells are necessary but I've never bothered to find out.
 
The absolute love for sharing this. I will try and make a SMT version of this for my own use, but that's going to be a while.. and I definitely won't open source the layout!

I like the layout as well, nice and efficient. If you want a SMT DipTrace layout of the relay, let me know!
 
I’d be in on a group buy for sure. However I agree with the 1590BB…125B would be super tight.

Well, super tight for me atleast. I’m not on your guys level lol.
 
So, I'm revisiting this because I am thinking of doing a "big box", 1590XX design and adding all the bells and whistles, including dual speeds and a cancel function.

I'll make all the files, including Tayda drill plans and graphics files available here when I do.

I think, based on where my market for production pedals is going to line up around vintage style dirt boxes, that I am officially abandoning this as a production project.

That frees me up to make it a Cadillac DIY project for the forum.
Awesome
 
Kudos for taking on this ambitious project; building upon the original UniVibe circuit that could use some additional mojo. Looking at your schematics, I don't see a pot for the Pulse control. Is this essentially taking the place of the the Bias trimmer?

I recently built an ElectroVibe Mini and I really like it! I can't help but wonder if the Depth control may be better served as 2 separate controls; 1 as a Mix between clean and wet (maybe the chorus/vibe switch could go away too?), and a Width control. I'm thinking of the controls on my old EHX PolyFlange and how you can fine tune the sweep. Just throwing out some ideas here.

Thanks for all your work on this project and all the ElectroVibe mods! I plan to build another EV mini and implement some of your recommended mods next time around. 🙏
 
Okay, back to a normal amount of controls and added the output for a foot controller:

Going to start on a board layout now.
That’s frickin sweet. Maybe I’ll be able to afford an actual hot rodded vibe one of these days.

So after you finish this project rotary sim seems like it’d be on somewhat the same playing field.
 
@Big Monk, are you still planning to release this PCB? I would like to build this or modify my Eletrovibe build to these specs, but I don't see a clear visual guide on how to do so. If you're planning to release this, I would just leave my EV alone and build this separately.
