Żłob Modular: New VnIcursal VCA v666 redesigned and more DIY friendly

[onurkalaycioglu]

Just ordered a TH SVF! excited! One thing I noticed is the BOM looks to be an older rev as it shows 2sa798 which you said isn't used any more.

thought i answered this. but im sure you figured it out by now. yes the new rev doesnt use the 2sa798. just 2 normal pnps.


new red and black aluminum panels are in for the minimix and svf. the screen printing clarity at fahrion is really impressive. my crappy over exposed pic
doesnt do it justice.

synthcube has a shipment coming in of the new panels and diy stuff. and analogue haven will have some built ones soon.

more aluminum panels are a coming in the new year as well as pcb panels...

[Whelm]

Awesome! I've got a few of my remaining dollars earmarked for the vincursal VCA once the aluminum is ready.

nvm

Looks good! I too have 3 vnicursal VCAs eagerly awaiting an aluminum panel upgrade!

[sleepgardens]

I must admit that I was skeptical about about the new graphics, it looked very cluttered to me. But instead it looks really really good!

I'm trying to source the components for the Entropy, which calls for two ADA Fruit 100k trimmers and 1 500k - 1M trimmer.

Unfortunately, even a google search has resulted in ADAFruit having only a 10K trimmer. Does anyone have a mouser/smallbear/tayda parts for non ADA Fruit trimmers as I can't seem to find them?

Thanks.

I just finished my TH SVF and its not working! I have built a lot of projects and have gone through the usual debugging. I can't find any solder bridges, and I've replaced all the IC's.

Im getting a lot of DC voltage on the outputs and as far as I know thats usually a no no in audio.
My voltage in (power connector) is +/- 11.98v

HP: 10.57v
BP: -11.20
LP: -11.88v
These voltages do not change dependent on the knob positions.

Also, the TL071 seems to get quite warm to the touch. Not quite smoking and burning your finger, but a big uncomfortable.

another note, when you touch the some resistors near the edge of the board with your fingers it makes some squeeling sounds.

[daynehacks]

Got it figured, After reflowing everything and swapping out the transistors it still didn't work. I grabbed a tl081 from my breadboard (known working) and replaced the tl071 and Yeeha! works fine.

I'm guessing my tl071 pile is a bunch of crappy fakes.

i think i sent you this already. but i get my trims at tayda. they are 6mm and 100k should work for all 3 trims on the entropy.

@daynehacks
glad you got it working


also i should mention theres new build docs for the vnicursal vca. and i also think i forgot to post that theres docs for the minimix too. its under diy-boms on my site.

also going to post a video soon of the new clk dv mk II which also has a new 2hp expander.

switching over many designs to white on black aluminum pcbs. so far with the clk dv, attmix, and dual vca.

new aluminum panels red and black panels for 2 new modules and the vnicursal should be in end of next month hopefully.

Yep, I just ordered it along with another ViNCursal, and I just got the shipping notice. Thank you!

I am building the Vncursal VCA now and I am a little confused about the leds. How do I know what resitor value I should use for my red leds? I´ve got red standard leds, the ones in the BOM. 10k?

EDIT: silly me, it is in the build guide: 20k for red leds

[Slomen]

I just finished the build of my vca today, I used 0805 for all the resistors and most caps apart from a few values I didn't have. I put the led resistors on the back of the board which was handy for trying a few dif values for the superbright leds I used. Ended up using 100k for most of them. Attached a few pictures in case anyone was wondering what the finished thing looked like as smd - it was relatively simple after getting all the 100k in place following the picture on the bom. Here's an insta of the light show

The panels look amazing up close! Pictures don't really do justice. I think because the details are debossed slightly, which is lost a bit in straight on photographs.

I got my pcbs from synthcube, and they are the old revision of the main board, which was a bit frustrating. I'm not bothered about the gain trimmers, but the hf bleed in the sum out is pretty noticeable. I'm not entirely clear on what the changes to the new board are apart from the trimmers, would it be possible to mod this older main board to get rid of the bleed?

Where did you buy the trimpots with the white lines on them?

well its 20k for the red leds that come in my kits. not all red leds have the same mcd(brightness). if you have your own standard red led it might be around 1k or a little higher.

yep you need the song huei pots


if i didnt mention it already. i posted a bunch of new build docs recently. theres now vnicursal docs for the mother board, and docs for the attmix and dual vca.

also i posted a vid in euro subforum. but you guys over here would probably like to know theres a new clk dv coming out

the new clk dv mk ii and expander are coming out in a couple weeks. i also fixed whatever problems there were with the last version not triggering with certain slopes and now triangles and sines at audio rate can be divided "clearly."

the expander adds switching over non-inverted, off, and inverted clocks of the 5 divisions from the clk dv. it also provides 3 non inverted divisions of 64, 128, and 256.

old versions of the clk dv are not compatible with the new expander....

heres a little video with the smrf

im cool now, i have an instagram....
https://www.instagram.com/zlobmodular/

also its hard to see but it will be released in black and white pcb/aluminum panel.



o and finally vnicursal, push vca, and miniatt black and red aluminum panels should in by the end of this month or so. and other black and white aluminum pcb panels will be coming out soon for the dual vca, entropy, mineq, and clk dv expander

[maltemark]

Great, looking forward for the entropy and clk div panel!

[daynehacks]

Definitely am into that new clk divider and the instagram account!

[GryphonP3]

Vnicursal panel put me down for three!

[Whelm]

God damnit I was going to try not to buy anything this month.

[Pokus]

if i didnt mention it already. i posted a bunch of new build docs recently.

I know this takes time, but would it be possible to post a new and updated BOM? I'm planning on ordering the vnicursal once the new panels are available. This is my first time ordering a full diy-kit where I have to source parts on mouser etc. and I'm spending hours trying to make sure I haven't missed any reistors / capacitors etc.

yep i will update it. but im actually working on a new revision of the top vnicursal pcb that changes the pots into attenuators when you plug voltage into the cv jack. trying to make it compatible with the recent revision of the vnicursal mother board with minimal if any modding.

also good news. the vnicursal vca aluminum panels are finally in! also i have new aluminum panels for the push vca and miniatt. so they will be released soon.



will post a buy button for the vi vca panel soon. they will be $10 each.


check out some new vids of the miniatt and push vca

Looks great! if we order the VCincursal pcb and panel set now which pcb version will we get?

[onurkalaycioglu]

Currently I still have the v4(with the trims). But the top pcb with attenuation feature will be v5 and should be out in a couple weeks. Have to do another revision.

Button is up to buy Vnicursal panels.

[onurkalaycioglu]

miniatt and push vca are available on my site now.

push vca
$95 built
$65 kit
$20 pcb/panel

miniatt
$40 built
$25 kit
$15 pcb/panel

should be shipping some out to control and analoguehaven within the next couple weeks.

Is there an ETA on the v5 VI VCA panels? Thanks!

Also curious on this. Got a few aliminum panels in my basket and would prefer to buy along with the new top pcbs.
