When are you adding in the FM sync and tuner so we can make our own.
(Come on, you were all thinking it! 
)
The tuner…probably never. We’ve got Sam’s boards for that (when they’re in stock) and I’m not really interested in the space it takes up to have it on all of my VCO’s.
The FM and Sync…maybe when I experiment with them on my 1222 and decide that I need them in my others 
They would probably fit on the 70x100 boards I’m using. I know I can’t fit the octave switch and the fine tuning knobs. (Ok, maybe the fine tuning could fit)
Mine are just designed to be quick simple and easy 4430 VCO’s that scratch my personal itch. But if someone else can get use out of them that would be great!

For me the fine tune pot is essential to tune all the oscillators easily (without taking a tone when you move the pot by 1 millimeter). I had done several VCOs without at the beginning, and I have added it to all of them now.

THX for the links @juggle… I have an old -MACBETH M3X- BASS-Synth MONSTER in my studio with 3 Oscillators and CV GATE outs on big Jack sockets for test applications…
but the synth need a doctor because the 2nd Oscillator and the filter unit has a malfunction and I’ve no oscillograph or Test Equipment to do it.
also the M3X is a prototype from Ken Macbeth. Inside the machine you find the following words are scratched on the bottom of the machine from the inside::
MACBETH M3X
Serial Number 0001
THE VERY FIRST ONE
EDINBURGH 2001 and the Signature from Ken…!!
so for me it’s very unique and my little treasure and thats why i’m a little bit sensitive where to give to for repairing…???

how much are the costs for the VCO PCB Boards…??
Speaking as a Scotsman from Edinburgh I can tell you that Ken is still very much around and active. I suggest you drop him an email about your M3X, maybe send him a picture.
What better way to find a fix than to go direct to the source.
That said if I remember the one i saw about 2005 was not terribly complicated, just well built and not in any way beyond a competent engineer.

Makes sense. I’ve drawn a ton of inspiration from your build and did notice you seemed to have added those in. Once I finish the power supplies on this second case I need to spend more time playing with the synth for a few weeks and less time building things for it 
I’m not actually selling them - I just etch my own as needed right now. But the gerbers are there so anyone who wants to is welcome to make some on their own or at a board shop. JLCPCB.com is $2 for 5 boards plus whatever they charge for shipping to your location. Probably about the best deal out there.

man that’s awesome price… and did you do the design of the frontpanels…??
he did’nt do repairs… in 2019 SCHNEIDERS BUERO in Berlin sent him 3 panels for repairing… they receive the items back after half a year with a short notice… sorry no time for that… HAHAHAHA typicly Ken

Hello, I’m Thomas from Belgium, currently 34yo.
I think I discovered LMNC through the 1000 oscillator video.
One video lead to another, a few weeks passed and now I’m here, just received my kit for the FC Microbus and waiting for the parts for the AS3340 VCO.
I have some electronics experience: some small cable repairs, replacing an IC in a Marshall MS2 (the tiny amp), soldering a distortion box for guitar (but I might actually convert it in a module).
@juggle your Github repo looks like a goldmine, all the basic modules to get started, thanks for sharing.

Hello!
I’m dustboxednorth, a 17 y.o. Minnesota-based experimental/electronica/synthpop producer/tinkerer. I’ve been doing stuff with computers (heresy, I know) and DAWs since I was about five or six, but only started making music that’s semi-listenable as of about 2017. I’d love to get into building big hardware synths and modular setups, but the only thing holding me back is money, so I think I just gotta look around for cheap components a bit harder. My soldering skills are questionable at best and I’ll probably polish them up a bit more when I get some more components and such.

JLC is really cheap - and their quality is pretty good too. I’ve yet to have any issues with them though I know a few people who have had a few minor issues on occasion.
I design and 3D print my panels, there are F3D files as well as .STEP and .STL and sometimes prusaslicer projects for them in my git. If I missed one let me know and I’ll try to add it.
Glad you find it helpful! I’m trying to find time to do some better organizing. It’s getting unwieldly having it all in one repo…but I don’t want dozens of repos in my github account for individual modules since then they’re hard to find. I need to put some time in and figure out of Github projects or organizations would be a better way to keep them organized. Or…just move them to bitbucket or gitlab where I know I can easily group them in projects…
Since we use gitlab at work I switched my repos from github to gitlab because of the simple way to make groups of projects, and to have just one front-end to remember…
I still don’t like git (probably never will 
) but that’s the only free VCS that’s left with some perennity, it’s a case of adapt or die …
(everything is still private in my repo…)

It’s annoying that GitHub doesn’t seem to provide a way to organize repositories — none that I know of, anyway. GitHub Projects seem not to be usable for this. Prove me wrong, anyone?
Anyway, what I’ve done is to address the problem of too many repositories by creating another repository: https://github.com/holmesrichards/Directory . Its only content is a README.md that provides a categorized directory of my repositories. And on my overview page it’s the one pinned repository. Obviously this has to be maintained manually (and will it be? HA!) but it’s something.

Yeah, it’s a glaring deficiency of github that I’m surprised they’ve yet to address 
I love git. It’s the only free VCS I ever found that was actually worth the effort of dealing with. And now it’s so second nature for me I freak out when I don’t have a repo to track things with on a project.
But github…I’ve only ever tolerated. We use bitbucket at work (mostly because they allow unlimited private repos for small teams and our team is usually small enough…and even when it’s bigger bitbucket is still cheaper than gitlab or github for private repos.) and it does have projects which are great for grouping related repos and we use that extensively. But I’m not a huge fan of bitbucket for my own needs because their interface just kind of rubs me the wrong way. I really like gitlab from the few times I’ve experimented with it - but the last time I seriously considered switching over all of the projects I was involved with were hosted on github so I was still stuck dealing with github. Those are all dormant now though and the few projects I do still follow are mostly on gitlab…so it’s getting really tempting to switch over.
welcome aboard , yes a lot of good info here and help .

yeah money can be an issue . but if you scrap metal , wood , plastic for panels and diy strip board the modules at first to get started you can always up grade later . thats pretty much what Sam , myself and others did to get started . but you will have to pay the electric bill though for this stuff to work , food not so much …
