Bring out yer Diptrace

Building pedals is the same way for me. I love designing boards, verifying dimensions, laying out graphics, etc. playing them when they are finished is awesome as well but the actual building is a lot like driving someplace: The trip sucks, is typically boring and is only redeemed by actually getting to the destination, which is often glorious.

The creative aspects are more exciting than monotonous assembly for me too. They also cost less money than building a pedal! I do want to be good at the more laborious aspects of the hobby too.

Homebrew is generally like farts. You don't mind your own, but you can't stand someone else's.
 
I haven't posted any of my recent projects, but I've been cooking up some more PCB designs. This one is a higher-gain overdrive based on the Southern Belle/Mach 1 circuit, but with some Timmy features wangled back into the circuit, like the EQ controls and the gain boost.

I've also tried to improve on the Six String Stinger circuit by replacing the BMP tonestack with an active baxandall EQ and switchable gain via changing the source resistors on the J201s. I haven't breadboarded any of these, which I know is probably some kind of pedal crime, however this is what I can do with what I've got right now.

I think the files for this are on my other computer, but I wanted to share this because I love how nicely the layout came out. A combination of using a large box (1590XX) and a fairly simple circuit meant I was able to keep it nice and tidy, and all the components are more or less grouped by function. This is a tube FX loop with a parallel clean blend.

Also I've decided for anything I'm going to do pick-and-place on, I'm going to start removing the designators. It looks a lot cleaner, and I always have the design files in front of me if I need to debug anyway, so no serious need to keep them on there.

@vigilante398 This is too clean, too pro, Mr Manufacturer 😜

But seriously, nice work. I think I would do the same, if I ever did a mostly SMD layout. Just keep designators for any parts I have to solder on myself.

I love what I see on this thread folks 😍😎😁🙏

Thanks man. V1 had some bugs, but I was able to get a working prototype. I'm going to wait on the V2 boards and do a proper build report. It blows me away that the original was a single sided hand drawn PCB!

Stoked to see this happening! And always glad to see more chorus. Definitely my favorite mod.

Edit: Did the original also have FET switching? All the more impressive that it was a single-sided board if so!

Yep, stereo chorus (mine is mono), flip flop, 2 LFOs, and noise gate on a single sided hand drawn PCB smaller than a 125B.

I was always a fan of the Rullywow libraries, always had good luck with those. I think I heard that there are Madbean libraries out there somewhere, but I've never tried them.

I just found an old post of yours on diysb with a link to the rullywow library. I have the Madbean library for kicad but I'm not sure if there's a diptrace one. There is a Madbean eagle library too though

That must have been what I was thinking of. I remember hearing there was another big pedal component library for DipTrace, now I can't remember whose it would have been. I've been the unofficial keeper of the Rullywow library for a few years now, not sure what happened to whoever I got it from :P

Well thanks for that! It wasn't on the rullywow site that I could find
 
You can convert Eagle libraries to DipTrace format. It requires a little manual labor after the fact (pin names are weird and things like that) but 90% of the heavy lifting is done.
