Answering comments I missed during the premier chat: AD725 -- yep, classic. I know it well. Just trying to keep it simple and cheap so there's an entry level project out there for absolute beginners. The LZX cadet encoder uses a similar (or maybe the same?) chip for RGB encoding. It's definitely what I'd recommend for people who are at that level. Will I do pre-builds? Yes, although I'd encourage you to take it on yourself. Soldering electronics is one of those things that seems intimidating but is actually quite easy and can even be relaxing. Anyone can do it. A N Y O N E. If you're at all interested in building this, but you're worried that you won't be able to, I WILL HELP YOU.
Hi! If you’d like, you can e-mail me through the site with a hi-res picture of both sides of the board and I’ll help you troubleshoot it. Most times it’s something simple, although things are considerably easier now that wiring isn’t required. That’s usually where the problem is.
Thanks! If you want, e-mail me through the site with the subject line "CHADAPTER" - include your name/address and I'll send you one of those little chicklet adapter PCBs. No need for wiring anymore!
thanks! don't hesitate to reach out for support. I don't check UA-cam that often, but the contact form on my website pings my email inbox, which I check daily.
You Rock Dude ! Thank you so much for sharing these wonderful devices with the community ! I hope my AliExpress orders turn up. I've ordered them from two suppliers, but at US$4 each it won't upset me greatly. I just wish it didn't take two months to receive ! Now I have to buy this new Arduino beast and build it with sliders into an old DVDROM case ! lol I'm very new to the CHA/V, you didn't include links to the PCB order page, JLPCB ? Your very long single CHA/V web page is a little difficult to parse.. sorry PS: Much cringe for the bottom of the soldered boards and all its sharp points dragging across your poor LCD screen !
Awesome! So much covered here... I really appreciate the Karl Klomp Kudos at the end there too. Tired of seeing people sell his mixer for rip-off prices! I grabbed a CHA/V board from THONK here in the U.K. & love it! Do you know yet if they’ll they be carrying these new boards? Thanks!
Is there a chance to open source the PCB layouts? It would be fantastic to be able to produce my own, since the original PCBs seem to be sold out at the suppliers listed on your site (at least for EU and UK). Or will there be available stock of them soon again?
Thanks for sharing all those information. I am wondering whether or how you attenuate the signals. Eurorack oscillators are 5V I believe and the VGA channels have a max rating of 0,7V (might be totally wrong though). Unfortunately are the boards sold out in Eurpoe :(
you are correct. these oscillators usually hang around 3v, but they could potentially even rise to the rail voltage. CHA/V devices rely on the forgiving architecture of VGA inputs, which specify diode clamps. Attenuating to 0-0.7v is theoretically correct engineering, but in practice, the color is quite dull. Overdriving the inputs gives nice blown out colors and aesthetically pleasing edges; similar to the idea behind a fuzz pedal. That said, VGA4EVA includes a triple filter/attenuator that helps with blending and mixing colors.
Is this something I can use for streaout music to tweak and glitch my video too? Do you make one that can create different glitch movements to the frequencies beat of music? I'm considering adding something like that to my project and record to video.
dang. i just finished soldering it all in and loaded up the chip like 4 times and im just gettin a black screen. any tips? all my solders look nice i think. triple checked everything.
Awesome! Look forward to picking these up. Do you need the conversion board to use the new board with the CHA/V 2.0 rev b? Or is it just for the older yellow boards?
The adapter is for 2.0 rev b. You got it. Email me through the website with the subject line "CHADAPTER" and send your name & mailing address -- I'll send you one. That yellow board in the vid was 2.0 rev a, but not much different from b. I made them in every color for the first run. It was fun to let people pick a color in the workshops that year. Most people wanted black anyway though, lol.
that's an FAQ for sure. I've been meaning to do an FAQ for a while. The short answer is yes. In the meantime, I have a page that talks all about that: jonasbers.com/vga-output-conversion/
I'm here 3 years late and enthralled.

rly excited to try this out, i could never get a signal out from my cha/v 2.0, so hopefully i get better luck with this lol

Can't wait for the rest of my parts to come in!
i love you this is amazing. just soldered the 2.2pf caps that i forgot to order-. now i can finally experiment my ass off. and learn coding arduino
Just ordered a VGA4EVA and CHA/V from Raw Voltage and am really excited to see what I can do with it.
Excellent! Good luck. HMU on my site if you run into any issues.
THANK YOU SO MUCH ILL BE ORDERING THE PARTS THIS WEEK
Definitely need one of the new boards as soon as they're available! Loved building the CHA/V and this would be such a good addition!!!!

This is the G spot...! great work and great philosophy... master piece!
Thanks!
Yay ! Awsome work
can't wait to get my hands on this.
Built it, it works great, thank you!!!!!
This is awesome. Instant need.
My dude. You are a legend!!!
Really excited for this.
Amazing work, thank you for this!
Nice!!
This is rad.
This was fucking dope. Subscribed now.
Wow!
Comment to help the algorithm. Keep it up!
ha, excellent.
PCBs ordered!
thanks! don't hesitate to reach out for support. I don't check UA-cam that often, but the contact form on my website pings my email inbox, which I check daily.
Ah! When will these be available? I have the 2.0 rev b and would looooove to get my hands on the new one!
SOOOOOOOOONNNNN!!!
Thanks dude ! such goodnesses

PCBs aren’t up for sale quite yet, but will be soon. Good luck with Ali!
@@jonasbers Ahhh thank you for clarifying, I was getting frustrated !

Half hour of Jonas nnnnngggggg
Haha! Hope you made it through the COVID era ok. Remember when we used to get to do shows? It seems like a different life.
@@jonasbers I do guerrilla sets in the woods now. I have some up on my channel and some duo pieces on wormlogo.bandcamp.com/music
@@lutzcore can't we just call them gorilla sets? I wouldn't be able to resist the urge to climb a tree anyway.
Where are the docs and code pretty pretty please?
not up yet, but soon!

@@jonasbers great, thanks for clarifying! Will do
Looks amazing, when/how can we order these through your shop?
They'll be available through a few online shops very soon.
@@jonasbers that's great, thanks
This is probably a dumb or at least a amateur question, But if i dont have a vga monitor can i use a vga to rca adapter to hook this up to a old tv?
that's an FAQ for sure. I've been meaning to do an FAQ for a while. The short answer is yes. In the meantime, I have a page that talks all about that: jonasbers.com/vga-output-conversion/
I built a vga4eva but I’m only getting a black output. I’ve had difficulty troubleshooting. Any suggestions?
me too. did you ever figure it out?
