anyone have info on some IN PRODUCTION modules that convert Euro 5v to LZX 1v?
it seems everything i’m looking for is discontinued!
also trying to find one that is 6HP.thanks for any help!

https://www.omiindustriies.com/webstore/curtailCurtail is a 4hp voltage scaler used primarily to bring signals from audio Eurorack modules (+/-5V) down to video Eurorack levels (+/-1V)
Price: USD 110.00

yeah passive will work fine!
since they can be an attenuator, 2 input mixer or a panner
the koma electroniks inline attenuators do not work very well as their useable throw for video is very short. Not sure what is going on there.

There’s a maker on Reverb building Cadet modules. Cadet V is 4 scalers in 4HP. If the Cadet V isn’t in stock, just message the maker and he will build it. I have the following:
5 to 1
+/- 5 to 1
1 to 5

From the LZX Cadet github:
LZX Cadet Series EuroRack Video Synthesizer DIY Modules
The designs and release artifacts for these projects are now open source hardware.
You may fabricate any of the original PCB & Frontpanel Gerbers for personal use without restriction.
You may not sell these modules, bare PCBs or kits with the original LZX artwork or under the LZX brand name.
If you sell these modules, open source your derivative work and link back to this repository.
this seller is not complying, so i would advise against buying them, out of principle.
this seller also sells teletect stuff, which im not fond of, though i never specified you couldnt sell them, i think its just bad form.
#7 — rempesm · 2023-03-01
This same person is also selling BSO, Syntonie and Foxing Hour modules with components not specified in the BOM. Whether they’re the critical components or more for aesthetics, it’s poor form to sell them like that.

absolutely!
what the FRACK?
i mean…
the creators have graciously given everyone explicit use of some of their designs like Ciat-Lonbarde.
if you have the skills and know how to build these things…is it so fracken hard to not brand or rebrand them and point back to the original source?
Cruc-FX and Meng Qi are two that come to mind who respectfully use open source Ciat-Lonbarde designs with great success!

This seller is also building my modules from pcb and selling them commercially.
I asked him to stop doing this, but never got a reply back
#10 — meudiademorte · 2023-03-01
isnt it possible to report him to reverb for violating “trademark” rights?
#11 — wednesdayayay · 2023-03-01
monome saw people starting all the way back in the 40h days copying their work and selling it without permission. Even people that are still around selling different stuff to this day…
On a separate note I commissioned meng qi way back in the day to make me a ciat-lonbarde expander that I bet you’d be interested in reading about if you haven’t @SPIKE
I love that Cruc-FX is so serious about not selling modules it makes me so happy to have been in the ciat family for so many years.
#12 — dryodryo · 2023-03-01
Oh, I did not know about any of that.
The maker was very helpful to me, building stuff that I was not competent to do.
So for him to comply, he would just need to change the artwork and upload the changes to GitHub?
Maybe I can convince him.

If he’s building for you on commission, no problem! It crosses the line when it’s advertised as an LZX Industries product publicly. If he wants to do that, we’d prefer he do his own faceplate design at least, and advertise it under his brand name, saying “based on LZX Industries Cadet open hardware designs” or something similar.

Yeah, I understand that. I do want him to change his ways, so before I approach him I need to understand the terms of compliance. Change the artwork and upload the changes to the repository. Anything else?

Hey @SPIKE, there’s also the Wrangler from Visible Signals.

#16 — creatorlars · 2023-03-01
He doesn’t even need to upload anything. Just not putting “LZX” in the product title and getting the front panels made with no silkscreen layer would be fine, for example. This isn’t killing me, it’s just a request. I realized this would happen from time to time if I released the source files.

I’m anticipating that he may say that “LZX” needs to be in the product title, because search engines. Is there any language that would clarify the status of the product as designed by LZX, but manufactured by another maker? Sorry, this is all new to me.
#19 — brownshoesonly · 2023-03-01
I in no way support or endorse this maker or anyone who sells BSO modules made by their own hands. I also sell an improved crossfader with correct parts cheaper than they do
#20 — Vdot · 2023-03-01
“based on LZX Industries Cadet open hardware designs” in the product listing should be sufficient for search algorithms. I think the major issue here is printing the LZX trademark on his product, which would lead to consumer confusion.

Ugh. This just gets worse and worse. I’m so sorry this is happening.
I will try to convince him, but it sounds like others have tried.

Martijn, can you clarify the issue for me? Is it that the commercially built modules should not have your branding?
How is what this seller is doing different from the commercially available built modules on e.g. Schneidersladen?
#23 — reverselandfill · 2023-03-01
My DIY products (schematics, pcb sets & kits) are available for users with a limited budget,
who want to make video art.
If you want to buy a finished module, I offer these directly, on my Etsy page and a number of shops worldwide stock them. (I’m working on having more shops in the USA right now)
The modules these shops offer (for example Schneidersladen) are made and tested by me.
External commercial builders:
Buying cheap pcbs and building modules from them, then selling these as a commercial bussiness is not something I think is ethical. This is a practice you see much more often now, especially with open source audio modules.
People make money without having to do any real work, and the designer gets (almost) nothing.
Where do you want to see your money go?
For the designer / maker this is a means to earn a living, continue their work and offer new projects.
For an external “bussiness” it is just easy money.

HOLY FRACK!
THAT LOOKS AMAZING!!!
i have a few of his early devices but not one of those!
now that i have delved heavily into the Ciat-Lonbarde sphere over the years…something like that would be AMAZING!
also…
apologies to everyone if this topic has really slid off into a litigation session over jerkoffs that just don’t have a simple modicum of respect for other people’s creations. A CURSE ON THEIR HOMES!
anyhow…
thank you so much for the info on proper conversion modules.
i hope that more of these will be available for the community.
seems like they are a serious basic tool needed for videosynths!
this is what i was building…
i found a used one of @brownshoesonly modules and picked up the suggested Curtail and figured a buffered splitter would be handy!
now i can connect a horde of Pamela’s NWO modules and various other noiz weaponry to the thing!
hopefully all the parts arrive by the weekend!

He could include something like, “designed for the LZX 0-1v ecosystem” in the description so at least the search picks up the “LZX” and there isn’t blatant trademark infringement.
#26 — dryodryo · 2023-03-05
Hey, just to give an update on the situation with the Reverb seller. He did reply to my message, said he has seen this thread, thanks for bringing it to his attention… but made excuses rather than taking responsibility. So, it does appear unlikely that there will be any positive movement on this.
Question … why didn’t LZX strike their logo from the open-sourced Cadet panel graphics? If I was releasing something out into the wild, I would take at least that minimum precaution to literally protect my brand. Anyway, it’s never too late to revise those graphics to prevent such shenanigans in the future.
Thanks, and again, I’m sorry this is happening. I tried.

It was as a courtesy to those with existing Cadet systems, and also because I wanted to preserve the project archive unmodified. The idea is to archive the project for personal use and historical purposes, not to publish a “print and sell” product design. If someone wants to sell it as a product, they can learn to make their own frontpanel art. If I were too worried about it, I would have never open sourced to begin with. So it’s okay – thanks for trying.
My heart on all this is of course just that “someone else learning something or contributing something back” is what I get out of the deal.
So I’ll be here, if anyone wants tips on designing or exporting their own frontpanel art.

would multiple complaints of a cease and desist nature to Reverb shut this down?
i know they can be a bit strict about customer issues…which tries to make a safe environment to order through the site.
back to the original topic though…another question for the group…
does anyone know the IN and OUT of the BrownShoesOnly 5:1?
is the 5v IN on the left column or the right column?
#29 — jwsmithwick1 · 2023-03-05
In should be on the left column
#30 — dryodryo · 2023-03-05
BTW @brownshoesonly what’s the status of your configurable voltage converter, XFMR ?
Also, great work on the user docs for VH.S … complex modules like Channel really benefit from such a thorough explanation and graphic.
#31 — wiatrob · 2023-03-11
Ahh bummer I never have time to troll the boards anymore… I have some Cadet Scalers I would have laid on ya for chips…
#32 — Jesse · 2023-03-25
Breadboarding a 5v to 1v w/ CV controllable slew rn, should be able to get panels/PCB’s on the next JLC order inshallah
#33 — Jesse · 2023-05-05
Our simple 2hp 4 channel bipolar 5:1 scaler is now available www.scopicmodular.com
#34 — dryodryo · 2023-05-08
By bipolar, you mean +/-5 V → +/- 1V?
Because some configurations of Cadet V can convert polarity, e.g. +/- 5V → 0-1V.
#35 — Jesse · 2023-05-08
Yep, exactly. ±5v becomes ±1vA 0-5V CV signal becomes 0-1V
Purple trace is a ±5v LFO, green trace is the scaled version
#36 — monads · 2023-05-08
That scaler looks really nice/footprint compact size!!
#37 — monads · 2023-05-11
Just placed an order for these to check them out!!!
#38 — Jesse · 2023-05-11
Awesome! We’ll get them in the post tomorrow
Thanks for your support, it’s been a fun little project 
#39 — giantmecha · 2023-05-23
Hey @Jesse ! Quick question with maybe an obvious answer. Will this module scale 10v signals down to 2v?
#40 — Jesse · 2023-05-23
@giantmecha Nah thats a great question, yep it sure will
#41 — giantmecha · 2023-05-24
Thanks! Snagged me one
#42 — Rik_bS · 2023-05-24
FYI your URL doesn’t work for me (in Australia)
#43 — jwsmithwick1 · 2023-05-24
Having trouble with the link as well
#44 — monads · 2023-05-24
I also found the link provided didn’t work when clicking in this thread. The workaround was to directly type it in your web browser and it loaded quickly.
#45 — joem · 2023-05-25
@Jesse I think I figured it out. The link in the thread is a https link, but your site doesn’t (currently?) do https, only http. I could swear I’ve clicked on the link in the thread before and it worked, so maybe your SSL certificate expired or was removed? Or maybe I’m just imagining that and it never worked with https?
#46 — Jesse · 2023-05-25
@joem ahh thanks, we dont have HTTPS certs/cloudflare setup so its http right now, must have typed the link wrong or maybe the forum tried to force https.
Fixed the link!
