My build progress

Some good new regarding the Kosmo Mulitool. Everything is working with the Arduino Nano Every so there should be plenty of memory for further development. I managed to set up some basic menu structure that is easily extendable so people can start adding their own stuff. There is not much functionality right now. My first module is a simple arpeggiator which is already working but still in progress. Expect a lot of code changes, this is all in a very early stage of development.

I uploaded PCB, panel and code to Github in case you guys are interested: GitHub - polykit/kosmo-multitool

Would you add a license please, to clarify if we’re allowed to make copies (ā€œforkā€) and changes?

Yes, I haven’t decided yet on this topic. I would like to have something that grants unlimited personal usage but prohibits selling it. Maybe I just write it down like this.

I use Creative Commons BY-SA (4.0 ?)on all my stuff.
It lets folks sell it, but they have to credit me and if they change it they have to share it under the same license.

I think that folks are generally respectful and wouldn’t just take a PCB design, get 100 copies printed, and sell them without asking the creator first.

Also bear in mind that you can’t protect the idea behind a circuit(or Behringer would be out of business long ago) but you can protect drawings of circuits - the schematic itself.

I don’t know, I think I will stick to the personal use license. I have no problem if someone is taking the circuit and designing a product out of it. But here it is only a matter of uploading some files to a PCB factory. I mean there are hundreds of hours of work in this. I want to give something back to the community and not fill someone else’s pockets. This is not restricting a commercial use in general, I just want to be asked.

I guess CC BY-NC license should fit your intention. It allows to copy redistribute and modify your works, but limited to noncommercial use. However it allows you to individually grant commercial permissions.

Btw. I would love to order some PCBs from you :slight_smile:

Ah, thanks, I will take a look at that. Honestly I don’t want to spend to much time on this topic. I doubt it will ever be a problem.

Sorry, I don’t sell the PCBs. But feel free to download the Gerber files and upload them to JLC or some other company and get them produced.

But be aware that this is not a finished product in any way.

Well, I usually check licenses when forking repositories, making changes or sending back pull requests. You could read it like this: Your license can be an invitation to others to contribute. IMHO worth the effort.

I take the attitude that (at least for anything I’ve created so far) I am not intending to profit from it. So if someone else does, so what? I’m not losing anything by it. In fact I can’t imagine anyone else making significant money off anything I’ve designed, so I don’t think it’s an issue — but if they do, it’s because they put the effort into production, marketing, and so on that I have no interest in. They might as well be rewarded for that effort. Being rewarded for mine would be nice, but I wasn’t expecting to be, so I’m no worse off.

So I usually use CC0, which is tantamount to public domain.

Obviously not everyone will feel the same way. That’s just my own point of view.

For those who feel otherwise, CC-BY-NC is a good option.

So hope I got it right and this is the official build progress Thread.

Started a year ago to do some stuff, slowly learning from the bottom. Had a long pause from September when I got stuck in my home-country when visiting my family :sweat_smile: but used to read a lot more about electronics, electronic music, etc.

Here is where I got:





Used the 20x10 cm format proposed by LMNC (it all started from his videos), yet im using 3.5 jacks cuz I’m trying to keep it as small as possible.

Yellowish light destroys the color - it a darker blue with a tint of green in it (see the last picture).

Here are the 3 modules finished:


The Arduino Baby 8 - LMNCs design
Its a even darker blue, spacey esthetics (as the whole thing actually wants to be in the end)


The MS20 LO/HI filter - LMNCs
Had Millennium Falcon in my mind for the looks… might be only in my mind :stuck_out_tongue_winking_eye:


Annnd a drone, based on LMNC’s Super Simple Oscillator’s.
You can stop the oscillators from the switches, CV to each individually or all at the same time.
But this feature works only with lfo source, the sequencer above can’t. This neewby version of mine has also other problems.

More things on the breadboard, more to get some panels soon.

(got some problems with some things so I’m thinking to open a thread ā€˜ā€˜help Amix9’’)

Nice looking case! Even from the back!

Use the search facility to see if others have asked about similar issues before, and be sure to check the FAQ category. If you still have questions I recommend posting to an existing topic or starting a new topic relating to the specific circuit rather than a ā€œhelp Amix9ā€ topic. It’ll be more useful for beginners who come along later and are looking for the same answers.

Woah! My case is just some timber I knocked together - I’m getting professional arcade cabinet vibes from yours!

Your modules also look great, what are you using for power?

Well done.

I just added CC BY-NC license to the repository.

Damn thats some nice work on the case, even your back panel looks nice!

Messing around with the MFOS Noise Toaster faceplate design. Wanted to cut down on the jargon as much as possible so my nephew can figure out how to play it.

Kosmic Superspreader design finished! I still haven’t breadboarded it but it’s simple so I might just order and see.

Oh baby, save one for me!

Nice, but I look at your build info to see what do this module,
and in the description i found this :

ā€œIt takes a CV input and a Spread inputā€

what do you mean by this Spread signal plz ?

btw i think there’s no value for the 2 pots in the BOM

@willow2x @Sonosus @analogoutput Thank you all for the input :slight_smile:

@Sonosus Power is a modest MaxWell RT-65B, switching, with +12V 2.8 A & -12V 0.5A
When I started I felt like I want the PSU to not be made by me…for safety. Will stick to it a while then build a more proper one.

The ā€˜spread’ voltage is added or subtracted to the CV voltage, and sent to the +/- outputs.

For example, it can be used to evenly detune 3 oscillators - I would plug the 1v/Oct signal from my keyboard into the CV, and the 3 outputs into the 3 oscillators. The Spread knob can be used to change the amount of detune, and is controllable with the ā€˜spread’ input. I hope that makes sense?

Edit: and yes I’ve been fiddling with the interactive BOM, both pots are b100k.

Edit 2: it’s pretty much this

There’s a good demo on that page.
