Very well planned little system! I wouldn’t have ever been able to settle on what modules I wanted in it, hence my two by 168 hp case for drum stuff only, and another melodic box that’s four by 126 hp! There’s really not much that your case can do that my melodic box can’t do, except I’ve got some different sequencers and effects. I can’t ever settle on my projects as being truly finished, so I never do finish them, they’re all work in progress. I can see many lessons I should take from you when I hear you talk about your box. Namely, to take the time to sort of revel in the successes and be sure to follow through with my plans to put the thing to use once it’s done, no matter what it is. I have many fears of exposing myself as someone who can become sort of obsessed with toys, and I really come down on myself for it every day. I applaud you not only in your careful planning and sound decision making regarding this project, but also in your seeing to it that you’re exposing it and showing it modestly, with an important message for people who might wish to follow your example and build something while not having tons of cash to pay out. A very valuable endeavor for you, and now an inspiring and helpful example to reach people who need it! It’s tough to find meaning and usefulness in these things sometimes, and I know it that you have done both. CONGRATULATIONS, AND THANK YOU FOR SHARING!!
This is a beautiful machine i´ve started to build one but at the moment the as3340 and the lm13700 completely sold out at my local shop. So i have to wait a bit. Thx for the video and greetings from germany.
from my experience building electronic things, although not modular synths: aside from some specialized chips, electronic parts like resistors, capacitors, transistors are on the order of cents, and you'll need some hundreds. pots, jacks, knobs, vero board, cables are a bit more but still cheap and there's far fewer of them. power supply, case, panels and graphics can be diyed as well. you'll need tools and consumables. if you already have some tools and are willing to do everything yourself (so nothing in the form of kits), i couldn't imagine such a project costing more than say 200-300 bucks (spread over several months), at least in my part of the world. if you don't have any tool it could get arbitrarily more expensive (although i think it's wrong to count the whole price of tools for one project; those tools are yours forever). if you also do that weird thing americans do where they count the hours spent working on something in their free time as lost wage, and you just wanna make music, you're better off buying used gear. if on the other hand you wanna build a synth because you love making your own things, and because it's a cool way of learning electronics and circuit manufacturing, and believe gaining skills and life experiences is more important than slaving away for money, then you don't need me telling you to do it. but it does seem to be a rabbit hole, so good luck.
What runs that midi to CV control? I really want to make a USB one for my rack but I don't even know where to begin, all my knowledge stops at analog :(
Very nice build, really impressive. Could you share a little bit more of info about the MIDI to CV module ? I've been looking for a budget way to do one, but with no luck.
i was thinking about building one, too. i guess you can just use a micro controller, use some midi library , do some calculations and send it out thru a DAC, then amplify the signal to Eurorack range.
Those guys are 3340's. There are a lot of schematics around for them. I actually rebuilt all three of them using the kassutronics schematic. That can be found here: github.com/kassu/kassutronics/tree/master/documentation/VCO%203340
@@otemrellik Thanks so much! I'm building a KOSMO format modular at the mo, but would like to do some of my own DIY modules at a later date. Yours look incredible. :)
Some were photo transfer and some were routed with my cnc then I used colored resin to fill in the lettering. The ones with finer detail were photo transfer.
Yoooo!!! I'm working on a cigar box with the same idea in mind, but using an arduino to do the Poly MIDI->CV. How are you doing the analog out for CV? Does teensy have onboard DAC or are you doing like PWM/using other modules?
Teensy does have an onboard DAC, but I'm actually using a couple external dac chips. I kind of need to revisit this module. It can be a bit glitchy at times.
Looks amazing!! I'm looking to make something similar and the resources in the description are super helpful! I have some questions though. What kind of wooden panels did you use? Are they about 2mm thick? And how do you mount your stripboards against the front-panels? Especially for the noise module this seems rather difficult. Thanks a lot!
I use a a lot of different types of wood. All 1/8" which is about 3mm. I found that attaching pots and jacks first to the panel then just finding a way to solder them to the protoboard works best. Here are some photos (noise and mult). imgur.com/RvOKp67 imgur.com/fFNB4K0
Really nice little rack!! Do you mind telling me where did you learn that photo tranfer technique? Didn't catch it in the video... I'm working on a system myself, lots of modules built, but I'm missing the faceplates
@@alebrenna441 The photo transfer I learned from the TheCrafsMan SteadyCraftin channel. You need a laser printer, some label relief paper and some transfer medium. It's a pretty cool process. The envelope was from electro-music.com/forum/topic-61297.html and I think the vca's were from kassutroncis site. Some of the modules were built a while ago and don't remember all the details.
Hey man, thank you for this amazing video I am from Brazil, and i must ask, do you sell or teach how to make the electronic project of synths and modulators? Thank you
I really could't say. I was learning as I built everything. Looking back at my instagram posts on this, it was like 7 months from my very first lfo prototype to this video.
really nice work man, put a little piece of wood over the hole, that case is really nice. i would of used only black knobs though... those teensy midi to cv chips are cool ans not too expensive (teensyy is expensive compared to others doing the same thing, these pt2399 tap tempo chips for example, they sell em 25 dollars, i get em for 7 euros)... but this unit is really nice, keep that enclosure. did you ever check the electric druides website? if not you might want to check it out. tthis guy is one of my heros
I actually recently rebuilt that. The new build is based on this guy: github.com/elkayem/usbMIDI2CV_MC Except I changed some stuff to do polyphonic cv and added glide functionality. That github project is a great place to start though.
Not currently. I did put a bunch of references I used in the description. Also check out modular in a week videos from Kristian Blåsol, they were a big reason I started this project.
Really hard to say since I ordered a ton of different components over the course of some months. Super ballpark would be around $200 for everything including the case.
There is really no code besides the midi-cv module. All the other stuff is analog. All the schematics I used were found online, I just modified some of them.
I was the one person who gave a thumbs down on this video. I think it speaks to our patriarchal culture that I knew this would be made by a male before even watching it. A woman could have easily built this, but his self assured attitude is very offputting to her.
