Missing Build Docs / Schematics

Any chance on getting the microblend schematic? Want an active blend but not set up for SMD so would like to Vero it
 
Just breadboarded the micro blend. Works, but I get bleed from both signals on either side of the pot. Working as designed, breadboard oddity, or I dun F’d sumpin up?
 
Any chance I could get the OG Synchrowah schematic? I've had the board for a few years and finally built it and I have no LEDs working at all, including the one for the LFO, so I need to start chasing voltages lol
 
Hey Robert,

Any chance you could upload the build docs/schematics for Acrobat?
I contacted Musikding, to see if I can buy the kit from them (I am in the EU), but they can only sell it if the build docs are online.
Thanks a lot!

For being such a simple chip, it's soooo hard to represent the 4007 in a schematic. The most beautiful I've seen is the original MPF-1 schematic, but even that is unwieldy.

My lifehack is to use symbols for discreet mosfets and NOT gates, depending on how the 4007 is configured in circuit, and tack the appropriate pin numbers on the schematic🤷‍♂️

Thanks for the schem! Now I know why that B10kDG does what it does. Mods ahoy!

I do 'em like this, that about the same as your method?

But uhh... that Stonedeaf schematic is... well it's certainly an interesting approach.

Edit: Just realised this read like I was complaining about Rob's CD4007 drawing, was referring to Stone Deaf's approach to the MPF-1!

Is there a drill template for the USB Pedal Power Converter?

If you like how that one turned out, I could share it.

Edit : you can now find it here

Here is the drill template I used for mine. Fell free to use.
Robert told me that if you use a 5mm Male standoff paired with a 20mm Female standoff (on opposite sides of the PCB) you don't need any mounting holes or hardware on the outside of the enclosure.

Hey,

I've been waiting to do a multiple PCB order, but am hesitant without getting the project documentation/schematics.
Waiting patiently for following docs : Quarry Fuzz, Silica Fuzz, Double Muffin.
thanks

Most Excellent! Thank good sir.
 
Not sure if this is the right thread, but I've noticed on several build docs that the switch position labels are missing. For example, the Pastel Preamp has two double throw switches, one engages the Hi-Pass filter, and the other presumably switches between 720hz and 400hz as the frequency for the low-pass filter, but the documentation doesn't show which is which.

Another example is the Equilux and Equilux Mini. The three rotary switches each have four positions that correspond to specific frequencies.

It might seem a little pedantic but even on something like the Skeptical Buffer it would be good to know which direction of each switch is the "on" position.

I really liked seeing the switch position documentation on the XC Phase. It was very helpful when laying out the labels / design! As a software developer by day, I tend to view the enclosure design as a small fun exercise in building a UI that is both pleasing to look at, and (more importantly) is clear as to what the pedal does / is doing. Having clear documentation makes for a much more enjoyable experience :)
