As more and more “DIY” makers exclude and hide their schematics for “copyright” concerns, it is really nice to see a kit with the primary purpose to teach how it works, rather than mindless assembly. Kudos to you and Erica Synths. I loved their Polivoks kit and I will certainly dive into this series as well.
This is the kind of thing that has been missing from pretty much every DIY community I've ever encountered. Congrats to Moritz and the folks at Erica on this release!
that manual is gold. pure gold. I found all parts in my lab and am currently setting up the schematic on a bread board. this project bridges the gap between toy oscillators without usable CV and temperature compensation and highly complex marvels which seem to work by magic alone. right on spot. this is probably the most accessible usable VCO ever. kudos for that!
I was planning on building the shapes Vco but I often find it difficult to skip to bits of a video that I don't quite understand or find component lists - the manual looks amazing!
Your video's are so informative, being interested in both synth music and electronics I have learnt so much more about how electronics behave/work. Amazing work.
Dear Moritz, this is not only a great product but also a great guide for DIY synth community. Thank you so much. I learned a lot from your channel by the way. Great work!!!
the modules look amazing! its so cool to see this project growing up, the best way to learn about electronics/synthesizers is building things, great job Moritz and Erika Synths
This is something very much appreciated. Not since Ray Wilson started his Music From Our Space, has anyone cared so much for DIYers and anfänger DIYers in particular.
Been seeing this kit all over but had no idea it was your work behind it! Fantastic job, it's been awesome to see you establish yourself here over the years!
The little prototype area on the side of the pcb is such a nice touch. Ngl, 71 Euro's (German shop is the closest to me) for a full VCO kit with FM and multiple waveforms is cheap! And we get the full technical breakdown to boot. You can't beat that. I appreciate your effort Moritz, it's always awesome to headsfake someone into electronic design, and you're doing that very well!
nice! i remember watching your passive patch pals video when i was just starting out, completely stumped because i didn’t understand how on earth that single JFET-VCA works!
Mine's in the mail, I'm very excited! I've been assembling DIY kits for a while now, but I'm doing it blindly. I've craved a deeper understanding that this series will provide. I'm sure it's going to be an enriching experience to build this series of modules, but I also know this will make it so much more enjoyable for other DIY kits in the future because I'll understand what's going on so much better. Thank you, thank you :)
Hey, kept an eye on this since you mentioned it! Really happy it worked out, congratulations! Also great work on this channel in general, all the best :)
I’m so excited for this! I truly appreciate the amount of effort and dedication you put into making this a reality. For people like me who struggle with some of the fundamentals, it’s going to be so great to have a chance to learn in such a guided, hands on manner.
Nice job! I’m currently going through the VCO serie and bulding one, your video’s are gold. Congratulations on achieving this release and the ones to come!
This is an incredible project, thank you guys for putting this together. This channel has already taught me so much, and I’m Incredibly keen to keep doing so in the coming months. Y’all are really doing great work.
Loved the whole experience so far, i congralute you also for adjusting the manual afterwards. Only 2 points of critique i'd had to offer would be to a.) make the case available asap because as it is i have a module lying around i cant test because i cant power it. and b.) to send out an email informing people that the manual has been updated as i was able to determine that there is some connection missing but i couldnt figure out by myself what it was. Just by pure chance i went back to the shop page and clicked on the manual again (even though i had it saved already) and noticed the changes. Both if the points are on the part of erica synths though i guess.. Anyway, thank you Moritz for giving me this opportunity, i enjoyed the experience so far!
valid points! the case and power supply are scheduled to release tomorrow. i‘ll see about sending out update mails for the manuals, but if you have an account, you can also follow me on instagram. i post about those kinds of updates on there.
As an addition. May I suggest the Ken Stone approach to future developments, where you can provide schematic variations, with which users that protobuild on a bread board, as well as a small protoboard area on the PCB to hardwire those changes. Just a thought.
So very cool, congratulations Moritz, amazing work. I look forward to meeting the droves of fellow newcomers thanks to what you're doing. I would be nowhere near as far along as I am without your education, help and inspiration. :D
@@MoritzKlein0 I'm heading back to review your quantizer circuit now (from the old days of your videos) and thinking about how I can use a programmable logic chip to implement the allowed notes. I briefly considered the 'all singing, all dancing' Arduino solutions out there, but it just feels like cheating - nothing wrong with that, but I want to be more hands on than that :)
@@MoritzKlein0 yes, or a PLD or GAL or something. I remember doing it at university with some fancy software. You can make the most elaborate logic circuits so easily. I haven’t really started researched it yet, but I got hold of a EEPROM programmer so that’s a first step.
Verry nice stuff. I find effect modules would be quite mezmerizing. Some ideas would be chorus and delay effects both easily achievable with BBDs (bucket bridge devices). It would be even cheap if the V3205 and V3207 were used and an external lfo unlike in a vintage guitar chorus is a quite nice feature I assume.
This looks awesome! With the diagrams this seems like it could be the Forrest Mims Radio Shack manuals of the Eurorack world. Excited to see how this all progresses. Congrats and well done! 😊
I've already build a custom rack and some modules myself, but these one looks so much better finished it's tempting to buy the kit to complement the system.
2 years later and I can still order this! It's affordable and available! I am getting into making music and its my dream to have a eurorack setup so I will probably be ordering like 3 total systems eventually.
Really looking forward to what else is coming! Unfortunately, I already built an oscillator, and I'm on a tight budget and missing other essentials (like a VCA and VCF), so I can't justify getting a second oscillator just yet, but I really LOVE this approach for DIY kits. This seems unique among DIY kits; most others that I've seen are like following the instructions for a Lego kit. They tell you what to solder and where to solder it, but they don't explain what it's doing, nor do they ever show the actual schematic. So they usually end up being a cheap way to build a module without learning much. And then if you need to troubleshoot any issues, good luck figuring it out, since you didn't learn anything in the build.
Very cool!!! I started out with Blacet kits, which were just a bit above what I'd consider beginner level despite their excellent docs. I wish I had started with these first! (I imagine the relative that got me into all this wishes I did too, because I asked him a TON of questions :D )
Your dedication reminds me of Ray Wilson's MFOS. This is pure gold for those who's just starting out and have no prior electronic knowledge, you're gonna have thousands of artistic sons dude!
Vor 50 Jahren war DIY im Synthesizerbau waaghalsig, teuer, langwierig. Ich fühlte mich mich wie Robinson auf einer einsamen Insel. Es gab kaum eine "Community" zum Austausch. Bis mein Modular "fertig" war, vergingen 5 Jahre und ich hatte keinen Pfennig Taschengeld angespart und 2 30er Visaton's geschrottet, weil sie mit den abgrundtiefen Bässen nicht zurechtkamen. ---- Das was jetzt z.Z. auf diesem Gebiet passiert ist fast paradisisch. Wünsche viel Erfolg!
Always happy to see such a well-documented creation! No doubt that an ambitious beginner could figure this out. Are all the kits going to be thru-hole, or are you looking at introducing surface mount components for the more advanced modules?
this is fantastic, very excited to get my kit - however, I have one question/comment... I noticed in the VCO manual, you don't get into some eurorack specifics e.g. reverse polarity protection, protect cv IO from unexpected inputs (voltages / outputs to outputs etc). I recognise, there was ALOT to get thru in the VCO being the first module - but I wondered if these topcs would be covered in other modules? Ive done a few experiments in oscillators/filters on 'desktop' , so my main interested in this series is how to adapt these designs for eurorack, how do I interface with eurorack... where a user is not just twiddling knobs, but is sending voltages... this series seems to be great for this, the VCO section on temperature control, voltage control pitch, v/oct adherence was nothing short of fantastic :) so im hoping you cover other areas that we need to be careful of when designing modules ... where users (me) do stupid things like connecting outputs to outputs ;)
girts from erica synths is explaining those things (reverse polarity protection, decoupling etc) in the assembly appendix - it‘s at the very end of the manual
What would an absolute beginner with no other equipment require to make this? Just a soldering iron and a breadboard for experimenting? An oscilloscope? Or does the fact I'm asking this mean this is too advanced for me? It looks brilliant.
absolutely required are: breadboard 2x 9V batteries + battery clip connectors jumper kit soldering iron solder it helps if you also get a multimeter and an oscilloscope, but they‘re not strictly necessary.
@@MoritzKlein0 Thank you Moritz! I've been watching a few of your videos today and I've never learnt so much in such a short time. I'm excited already. I started reading a list of 'necessary' tools for soldering and there were so many, it was beginning to put me off the whole idea, but I'll just get the things you said, along with your VCO kit, and see how far I get :]
The only thing I think I'd enjoy more than assembling this kit and (finally) getting into modular would be running it through my Strymon Night Sky. Ohhhhhh man. You are doing the Lord's work, sir! Will the schematics for the entire setup be available to download and build from scratch if we want to? And maybe the faceplates to buy separately?
the manual (which includes all schematics) is available here: www.ericasynths.lv/media/VCO_FINAL.pdf - we currently have no plans to sell faceplates separately, sorry!
amazing. Thanks for this. I'll defo buy this system. Do you do paid 1-2-1 lessons? I've been eager to learn these basics but never been able to find a teacher.. if so... where can I get in contact? I have ideas for a drum machine but never been able to understand the basics of how to build anything. Done kits before but has never really taught me anything other than soldering. I'd like to take it all to the next level - I think these kits will be for sure. Cheers
Having the PCB and all the parts would be very nice but it does seem a little pricey. Hopefully there will be an American supplier since post out of EU can be hit and miss.
I built the vco and it sounds great but unfortunately the pitch is really high. If I were to add a larger value capacitor at c10 next to the 2.2nf in c9 would it give me a lower pitch? Thanks
Mine is on the way! Your work is fabulous. I am also looking forward to getting this case! Just curious, will the released version be tapped only for the module widths in this series? Wondering because I'd be a shame to have to tap my own holes just to use different modules in the case.
i wasn’t involved in the design of the case, but it looks like it is tapped for the modules in our series. i‘m guessing this was done to keep cost down. i will check back with es and talk about it in a separate video!
This is awesome! Will we be able to purchase just the PCB and panel for those of us that source our own components, or does that not really factor into the price too much?
Hello Moritz! Is the case shown in the video the one that will be sold by Erica Synths to house this series of modules? So, will we have enough space for 2 envelope generators just like shown here?
@@MoritzKlein0 Thank you for the answer! Could I ask you something else? It's about the ICs, I'd like to put them on sockets instead of soldering them directly onto the pcb. Do you think there's enough space between the pcb and the front panel to do this?
Moritz - congratulations! I have been watching a lot of your series and inching up to the plate to try from scratch but in hopes you might indeed release a kit and here you have! Question - I'm in the States. If I purchase from the states vendor for more affordable postage (if the case) is it still fair for you?
the chips are pretty sensitive to reversed polarity (+ to - and vice versa). so there's a high chance they might be toast. luckily, all the chips used in this design are widely available and cheap!
Hi, i assemble 2 vco on maker board, but on one of them meet issue: when i use my midi Keys via midi to cv -i found that vco can not play correctly 1v/octave range (it more higher than 1 octave, an on another vco it is almost ok but only in 1 octave. Question-what part of sheme can be corrected, seems component problem, thank you in advance
Great! What realistic background is needed to build it and undestand the manual? I do not know a thing about electronic theory, I have never touched electric components and never used a solder :)
this specific kit & manual is very beginner-friendly. i‘d say you only need some basic knowledge about synthesizers (i.e. having used one, roughly knowing what a VCO does etc.). if you‘re unsure if you‘ll be able to tackle it, you could read a chapter of the manual - it’s available for free on erica synth‘s website: www.ericasynths.lv/media/VCO_MANUAL_v2.pdf
@@MoritzKlein0 Thanks! Went to rewire the whole breadboard today and realized the CD40106 chips v+ leg was missing 🤯Spent a good 1.5 hours yesterday trying to figure out why it wasn't working.
Hello ! I have just received the kit and I am having a problem with the volume. I can't hear anything coming out of the jack unless I connect to an amp and turn the volume up to near maximum... Is this normal or did I miss something 😅 Thanks a lot for your work and these amazing kits!
@@MoritzKlein0 i've been trying with earplug with a 4 contact point jack , stereo jack/jack to a hedset (no sound with these two) and a stereo jack to the amp where there is a sound only with max volume . Maybe i should also try mono jack ? And i've forgot to precise that i'm only to the first transistor step !
Fantastic! Definitely want >= 40 of each if you and Erica would wholesome. (Tried to leave club website here, but the comment keeps getting deleted) either way, very inspiring

I had the power config all wrong. Is it possible to blow things up? or will they be ok and I can start again?
the chips are pretty sensitive to reversed polarity (+ to - and vice versa). so there's a high chance they might be toast. luckily, all the chips used in this design are widely available and cheap!
Hi, i assemble 2 vco on maker board, but on one of them meet issue: when i use my midi Keys via midi to cv -i found that vco can not play correctly 1v/octave range (it more higher than 1 octave, an on another vco it is almost ok but only in 1 octave. Question-what part of sheme can be corrected, seems component problem, thank you in advance
I get + and - 13V from the PSU not 12V, is it still safe to connect the modules or is that already to high?
Sounds great !!
Great! What realistic background is needed to build it and undestand the manual? I do not know a thing about electronic theory, I have never touched electric components and never used a solder :)
this specific kit & manual is very beginner-friendly. i‘d say you only need some basic knowledge about synthesizers (i.e. having used one, roughly knowing what a VCO does etc.). if you‘re unsure if you‘ll be able to tackle it, you could read a chapter of the manual - it’s available for free on erica synth‘s website: www.ericasynths.lv/media/VCO_MANUAL_v2.pdf
Is there a discord or someplace I can reach out for some help? I’m trying to breadboard this vco, not getting any sound and can’t figure out why.
yup, here: discord.gg/apsVVX5x
@@MoritzKlein0 Thanks! Went to rewire the whole breadboard today and realized the CD40106 chips v+ leg was missing 🤯Spent a good 1.5 hours yesterday trying to figure out why it wasn't working.
@@adroc9841 happens to me all the time. glad you were able to fix it!
Hello !
I have just received the kit and I am having a problem with the volume. I can't hear anything coming out of the jack unless I connect to an amp and turn the volume up to near maximum...
Is this normal or did I miss something 😅
Thanks a lot for your work and these amazing kits!
what are connecting to the jack? headphones? what kind?
@@MoritzKlein0 i've been trying with earplug with a 4 contact point jack , stereo jack/jack to a hedset (no sound with these two) and a stereo jack to the amp where there is a sound only with max volume . Maybe i should also try mono jack ?
And i've forgot to precise that i'm only to the first transistor step !
@@vigar2351 so you haven’t set up the op amp buffer yet?
@@MoritzKlein0 I have set up the op amp buffer, the transitor and the potentiometer
Really great work! I have an analog club at UT I want to buy these for. What do you think you will have done by May?
the plan so far is VCA in feb, envelope in march, mixer in april, VCF in may!
Fantastic! Definitely want >= 40 of each if you and Erica would wholesome. (Tried to leave club website here, but the comment keeps getting deleted) either way, very inspiring
Is it possible to get gerber files for this kit ?
Will your DIY modules become available from THONK??
the VCO is on thonk already - will be in stock again very soon!
I can't find the specific schottky diode the manual calls for, would any other schottky rectifier diode work?
maybe try the 1N5818 if you haven't? otherwise, yeah, others should work too.
@@MoritzKlein0 thank you for your reply I'm looking forward to building your circuits and learning more.
Does it come with components or without?
with components!
@@MoritzKlein0 cool!
wow thank you!!
Good plan. Delicious.
Any plans for kits sold in America?
as far as i know, Synthcube will be selling them in the US.
O wow, this is my first time seeing a diy kid that is not priced 200€+ .
Will building it count towards university credit?
have your professor call me
