Ha! I’m working on making one of my V1’s into a breadboard too! Great minds think alike.
I’ll have to place a V2 order with the Snow module when both are available…

That’s an excellent idea! You guys are clever.
That’s awesome @rempesm
Are most or all of the passives the same as in the BOM? Now that I ask, I don’t remember seeing one but surely there is.
Did you have to do any major customising to make this work?
@joem, have you or are you planing any useful mods to create your version of this fixed breadboard setup? Just curious but I’m really tempted to try this too.
@reverselandfill, is it possible to power the experimental board from an external PSU? Like a standard 15V AC from Doepfer for example.
the build files are here:
The BOM is included in the buildguide, because you can build it in several ways.
you can power the VEB with a dual (eurorack or bench supply) PSU. -12 and +12
I added an external power input (left next to the 16pin header)
You cannot power it with an AC brick. This board needs DC.
If you don’t have such a powersupply, you can also use 2x 9v batteries.
(PM me if you need assistance)
Cheers @reverselandfill for the link & info
DC PSUs are definitely easier to source so I’m glad to see that. Is the power socket footprint on the PCB a particular standard? Ah, I’ll have a look in the build instructions & update this if the answer is there.
Update: there’s a nice closeup of the power input feet in the build guide but I’m not familiar with this type of power connector
A small suggestion would be to turn the 3x2 footprint of POTH1 90 degrees to match the layout of the pot. POTH2 is perfect although to the side of course.
What are the values of the 3x pots? Surely B10K.
No, I’m planning on doing pretty much the same thing as @rempesm – I’m just waiting for my female headers to arrive. Didn’t have enough for this kind of thing already on hand when I started.
The pots can be whatever value you need for your circuit. Chances are if you’re building some Cadet/Castle circuits that you’ll want B10K since that’s what most (all?) of those use, but it’s entirely up to you.
in v2 of the VEB the pot & switch headers are better aligned. (and better labeled)
I mainly use 10k pots.
Just double checking my work on these DIP adaptor boards for ADA4851-4s with the buffer circuit on LZX’s Github. The VEB makes tasks like this feel less annoying to start. Thanks again @reverselandfill
I see this Polarised cap between opamps non inverting input and gnd in the unity gain amplifiers for +1v and 0.5v.
What are they there for? Is it extra noise protection? Or do they stabilize the opamp in some way…?
It acts as a First-Order low pass filter.
Are these boards still being made?
Nice! Yea I checked with Thonk and it looked like they were sold out which is why I was askin. Will definitely have to snag one!
you can buy one (or a pack) directly from me (with some forum discount)
