Title: runoffgrove mockman PCB?
Post by: movinginslomo on July 10, 2024, 09:01:24 PM
I know there's a vero layout, but does anyone make a PCB? Preferably to fit in a 1590b?

Hi.
I love runoffgroove designs so I've designed quickly a PCB for you.
Check the attached files and tell me if you want me to put the PCB on OSHPARK.

I'll post a pdf file with BOM and basic drill template soon.

getting ready to solder.. does this take an spdt on/on or on/off/on? I'm thinking the former?

I'm curious to see how this pans out for you in terms of sounding like a rockman.  Hoping for some sound clips??

will do in time.... the breadboard version is promising

Just a note
Cybercow over on PPCB had a x1000 PCB at one point. Also, see the proposition PCB. Maybe will scrath an itch.

It's on/on.

I was assuming, but didn't want to resolder. I may start soldering today even

Bingo, the Proposition.  I like that circuit and I thought it did a really good job of covering the tone of the original but the Rockman sound is also based on the delay ("reverb") and chorus so it took a fair bit of stuff to duplicate.

Still it sounded very cool and I've loved the pedal.  I don't get a chance to play it out live but at some point praise band music will come around to 80's radio rock and I'll be at the forefront :-)

Totally get where you're coming from! I've seen a few PCBs that work with vero layouts, especially on sites like Tayda or even in some DIY pedal forums. They usually have designs that fit perfectly in a 1590B. If you're up for it, designing your own with software like KiCad can be a fun challenge too—I tried it for a couple of my builds, and it was really rewarding to see it all come together.

She's finally together boys, but she's passing a very weak signal.. any ideas where to start? I checked with multiple IC's (including verified legit new) so I don't think it is that

Voltages, clear closeup pics or front and back and a schematic. Reflow all your solder joints, check for bridges and reflow all your solder joints.

reflowed and checked values. I did notice on zombiesnore's build doc it calls for a 47n output filter cap while on the runoffgroove site it calls for a 470pf cap. I am using a jrc4558 op amp. I am going to breadboard this circuit and see if I get the same result

If there's a difference between my doc and runoffgroove's schematic then the mystake is on my side of course.
I'm not at home this week so I don't have access to my files for checking any mistake...

when I get time I'm gonna try and breadboard the parts and see if it works as intended.

Hi !
As I don't have access to my kicad files, I've downloaded my own pdf...
1) Why didn't I put my schematic on the pdf ? Why ? :-/
2) On my B.O.M. the output cap, parallel to the volume pot, is C7 and call for 330p to 680p (Cx on runoffgroove's schematic). So no mistake here. 470p is a good start.
3) Can you post photos of your build, maybe it's a simple wiring issue ?

Footswitch wiring scheme is the same as the one found here https://www.madbeanpedals.com/projects/_folders/DistBoostOD/pdf/Deadringer2022.pdf (left switch of course.)
For the jacks, pads are left: GND, right: signal, components side.

yes I used madbean switch wiring. I'll try and get some pics when I have some time

Here's my schematic attached.
Main difference is that I put a 1N5817 diode instead of a 100 Ohm resistance.
Added a 100n capacitor for IC power filtering.

On your pictures I didn't see any wiring mistake so maybe just reflow everything and check for bridges ?
Title: Re: runoffgrove mockman PCB?
Post by: movinginslomo on April 30, 2025, 07:22:09 PM
ah thanks I'll breadboard at some point
Title: Re: runoffgrove mockman PCB?
Post by: movinginslomo on May 03, 2025, 01:54:52 AM
ok I breadboarded zombiesnore's schem.. still weak signal. Must be some user error on my end if this circuit is verified. I did learn how to transfer a schematic to breadboard.. so win anyway?
Title: Re: runoffgrove mockman PCB?
Post by: zombiesonore on May 04, 2025, 03:46:11 PM
Hello,
I've breadboarded my schematic this morning. It's working. I failed to ear a difference with the switch on or off but definitively not a weak signal, quite the opposite.
One thing, replace the 1N5817 diode with /or put a 100R resistance in series after it, it tame the background noise of the circuit.

do you mind sharing your breadboard layout? it would be hugely helpful to make sure I'm not getting something wrong on my end.

If I could I wouldn't mind but I've removed the components from the breadboard a few hours after doing it.
I've never had a circuit working on breadboard on the first try.
For this one, on first try => nothing. Check => forget to connect the opamp to +9V...
Breadboarding needs to be 5x check. It is tedious but a simple circuit like this one is a good introduction.
Good luck.

found a similar breadboard layout from beavis audio for he version 1 mockman that I applied here. only difference is the op-amp is wired backwards and I eliminated the LEDs used in version 1. seems to work. Now back to the soldered PCB and see what's going on
