Hello fellow vidiots,

Wanted to do a check-in on cases/power supplies. Has anyone tried any of the following setups with a combination of video and audio modules, and gotten good results (i.e. minimal noise)?

• Intellijel 7U performance case w/ TPS80W
• Make Noise 7U Steel CV Bus Case w/Power
• Arturia RackBrute 6U

Or anything else portable/comparable that I’m missing? Obviously Vessel would be the best choice, but just wondering what else is out there and worth looking into.

Thanks.

I used the Make Noise 3u skiff and had no issues. I used TipTop Mantis cases and they worked well, but I eventually ran out of power to supply a full case of video modules. I went Vessel and have never looked back. Tons of power, smart syncbus options between cases, and glow in the dark bumpers!

#3 — destroythings · 2018-08-16

I also previously ran my video modules in a Make Noise 3U skiff but I had problems with noisy images that I guess was down to the power supply.

After that I had everything racked in my custom

Made case with Tip Top Audio Studio power boards and didn’t hit any problems.

Now have everything in a Tip Top Mantis and haven’t had any powers draw problems so far.

I have a mostly full diy 7U 84hp with audio and video and using 4MS Row 40. The only video modules are Cortex and Staircase and I have about 20 hp left to fill but I’m closing in on the power limit, or at least a comfortable distance from totally maxed out. It’s possible that there is some noise introduced in this setup but I don’t think my eye is discerning enough to notice. I’m toying with the idea of adding a Row30 to use just for audio mods and keep the Row40 for strictly video.

#6 — jameswashington · 2018-08-16

I own the Intellijel supply and can verify that it is a bit too noisy for video. (This was especially apparent in shape generation w/ Navigator/Shapechanger workflow.)

#7 — creatorlars · 2018-08-17

Malekko has the power boards back in stock, we will have them on our webstore soon (and 15 Vessels available.) I felt like high frequency ripple in the Intellijel supply was pretty noticeable. I’d recommend a power supply architecture that has a switching supply followed by LDOs (Tiptop Mantis and Studio Bus, Doepfer PSU3, etc.) or a fully linear power supply.

#8 — giantmecha · 2018-08-17

Thanks for everyone’s input, super appreciated. I have a linear PSU in the studio — got my hands on a cheap Erica Synths Monster Case with integrated PSU awhile back, which has been super solid. The Vessel definitely seems like the best choice for a portable rig, and I love the design. @creatorlars, are you working on a “lid” accessory for Vessel? Or is it more designed for transport inside an actual/rugged case?

#9 — creatorlars · 2018-08-17

Vessel is meant to be a housing/power for modules, transported in something like a keyboard gig bag or transport case, mounted on VESA mounts in the studio. But if you’ve got a big linear PSU already, definitely stick with that! Linear will always be ideal.

#11 — a_digital_index · 2018-09-02

Does anyone here have any experience with the Pittsburgh Modular cases and Power Supplies that come with them? I’m thinking specifically of the 420 rack.

Having a case-space crisis and this would give me room to work with but I’m really dumb when it comes to power requirements.I’m only using video modules.

#12 — drumasaurusrex · 2018-09-02

I was about to ask this same question yesterday and got sidetracked. So I am interested in anyone’s input, too. They seem to supply plenty of power, and they look like linear power supplies in the Structure-EP line of cases… but I don’t know much about power supplies.

#13 — creatorlars · 2018-09-03

Structure 420 is one of the worst offenders of high frequency ripple we’ve measured so far, so we don’t recommend it.

#14 — a_digital_index · 2018-09-03

Thanks Lars. Back to the drawing board.

#15 — creatorlars · 2018-09-03

Just get one of these and wire it to passive busboards:

#16 — a_digital_index · 2018-09-04

That’s more than I feel safe doing. It looks huge! Can you walk me through it? This will help me learn about power. I’d be happy to edit the process and generate a doc for your knowledge base on the site.

#17 — jnoble · 2018-09-04

May I suggest you not work with mains voltages unless you already know what you’re doing or have some in-person expert guidance?

#18 — a_digital_index · 2018-09-04

I appreciate your response and you are correct. I don’t have the experience to deal with it. But! I have access to people who do this stuff in their sleep. So all hope is not lost.

#19 — creatorlars · 2018-09-04

I’m definitely happy to post some pictures of our studio rig (which is 5 subrack frames and one of those Acopian supplies.) John is correct though, unless you know what you’re doing (it’s possible to learn!) then best to defer to the experts. The Acopian supply itself is pretty basic – I have mine wired to the fused IEC inlet on my ADDAC rack frame, so it connects to the mains on the other side of that.

#21 — luix · 2018-09-05

I think MP has the same amps compsuption per hp as any other LZX, its a rule of thumb that Lars keeps mentioning

#22 — creatorlars · 2018-09-05

Headroom never hurts, but powering up to the quoted specs should be okay. Just watch out for heat. The Memory Palace has an aux 12V DC connector to power the digital platform’s core circuitry. This reduces the power draw from 650mA on the +12V Euro rail down to just 40mA on +12V Euro rail if you power it from an external wall wart adapter. You don’t have to worry about it being a switching supply in this case, because it’s powering the digital rail only (analog rails are derived from the clean euro supply’s +/-12V.) If you have the Vessel case, there’s already an internal DC jack you can use for chaining. We have a small access panel planned for this, too (that gives the Vessel case power/sync chaining features to the front of a rack in a different case.)

The Erogenous Tones Structure module will have the same technique for sourcing digital power externally from the EuroRack rails as an option. Rick and I have worked on the circuit together.

Even at 650mA, which is over the typical LZX budget, if you balance it out with some of the LZX modules which are under the power budget per HP (Escher Sketch is one!), you should still be okay. I’m currently running a full Vessel with Memory Palace and Escher Sketch, and the top row full of Expedition modules, and having no issues running it all off the Malekko Power.

#23 — Tan_Sat · 2018-09-24

Has anyone had problems with the mantis case and Cadet modules? Seems like most are a little too deep for the mantis case (65mm on the VCO and SyncGen), at least on paper.

for some reference for those who aren’t sure I’ve got a case that is powered via a 4ms black row power, 4ms shrouded bus board and 4ms power brick that is getting some noise

my vessel and vidiot are beautiful and clean but 4ms is leaving something to be desired.

#25 — Agawell · 2018-11-10

I just checked

cadet and castle modules definitely fit in most of top row and all of bottom row except the very ends

the only issue is that the power cables need space too

I think you’d be ok if it was a few cadet modules spaced out between shallower modules and not a full case of cadet/castle modules

I will try to remember to post again next week… I have a visual cortex on it’s way and will need to move that and at least some of the castle/cadet modules into the mantis when that arrives

#26 — Tan_Sat · 2018-11-10

Thank you! I wound up building a case out of this: https://www.harborfreight.com/4800-weatherproof-protective-case-x-large-64250.html

And a Malekko powered buss board.

#27 — Agawell · 2018-11-10

cool - have fun!!!

cadet, castle, razzmasynth and??

#28 — microtonal · 2018-11-11

Wednesdayayay,

You may want to try a solution like the Genus Modu LIBB + EHA to clean up your row power:

http://www.genusmodu.com/products/eha.html http://www.genusmodu.com/products/libb.html

#29 — Tan_Sat · 2018-11-11

Just a looping envelope, LFO, and three attenuators. Gonna have some BSO in there soon!

#30 — Agawell · 2018-11-13

Update… i just built a cadet vco last night and it’s a wider board than the other cadet and castle series builds i’d done before…

It just about fits into my bastl marton case… will check the mantis tonight… but doesn’t look good…

was hoping to put everything that needs synch in the same case …

#31 — Agawell · 2018-11-18

another update - as suspected the wider boards (vco and synch gen don’t fit in the mantis - they’re a couple of mm too deep

#32 — sean · 2018-11-20

I realize that starting small doesn’t always pay off in the long run (it’s a slippery slope, innit?), but kind of want something reasonably portable to pair with a Vidiot.

Anyone have experience with and/or thoughts about something like the Pulp Logic LBZ54? I can’t 100% parse what they are saying about the power supply there, how clean it will be, etc.

Or other suggestions for small, ultra-portable cases?

#33 — alexpelly · 2018-11-20

I see that the Pittsburgh 420 is no good. Has anyone used the Pittsburgh Modular Structure EP-360 Eurorack Travel Case for their video rigs? Is the power supply the same as the 420? I’m looking for a good 9U travel case with a lid.

#34 — alexpelly · 2018-11-21

Also I just stumbled upon the MDLR 12/104HP portable eurorack modular case “performer series” with 2 Doepfer PSU3s. Any concerns about using that for and all LZX video rig? I guess I’d just have to connect my sync across the two compartments, right?

#35 — Agawell · 2018-11-21

if you look near the top of the thread @creatorlars recommends the PSU3

so yeah you may need to run sync between the two halves

if it’s deep enough (& it is!!! you need 65mm+) then you could do it with a cadet sync gen (plug say vc into in from the other half) there was some talk about a module for syncing different cases - but I guess that’s on the back burner

or you could trail a cable between the 2 cases through a 1hp gap perhaps, or make a custom rca cable going through 2 drilled 2hp panels

or you could just put all modules that require sync in one half and the ones that don’t in the other - if the psu will take them - watch out for the -12v only 1200mV each - which gets used up quickly

I think that if you want a full 6u 104hp LZX rig then you will either need the malekko power system (as used by LZX in their cases) or you probably need 2 psus to cope with the -12V

#36 — alexpelly · 2018-11-25

Ugh, yeah you’re right - the doepher psu 3 is not enough power for 6u 104hp. I love that case though because you can carry it on a plane and leave all those modules patched. Has anyone found something similar that works for LZX? I currently have a 6U 84hp bento box that I put malekko power in, but it’s full and I’m really struggling to find a good portable, carry-on sized upgrade.

#37 — Agawell · 2018-11-27

there was iirc a erica synths 6u portable case (before the current aluminium one) that had over 2 amps for both +/- 12v rails - but no idea if the psu was quiet enough for clean video

#38 — Agawell · 2018-11-28

if you don’t use stackcables, you could take a look at tendrils - they’re right angle patch cables - which might work for you - and eliminate the need for a deep lid

#39 — a_digital_index · 2018-11-30

New Case Question. I know slim Skiffs are all the rage these days but some of the Cadets and Castle modules are kinda deep. Can someone recommend a skiff that is deep enough for these modules and has a sufficient power supply?

#40 — Agawell · 2018-12-01

well the cadet sync gen and vco are 65 mm deep - that’s pretty deep for a skiff (they won’t fit in a mantis)

you could try mounting the pcbs in the case (there are nice holes at the corners of the PCBs wihc could be used for standoffs) and using wires to the panel or sandwiching a couple behind a larger panel (or a combination of panels and again wire them to the panel - the only issue I see here (and I’ve thought about it) is that with the pcbs at 65mm you need at least 13hp - and allowing for the jacks and pots and the 2 boards you’d get pretty deep

#41 — VideoFanatic · 2018-12-11

Hi there, I am currently thinking about getting a Make Noise 104HP Skiff for a system of Cortex, Polar, Marbles, 4MS Buff x2, Bridge x2, Arch and Shapechanger. Do you think this would be ok to fit in that skiff and to be powered by the Make Noise power supply? Many thanks!

#43 — 337is · 2018-12-12

Have you set up your desired modular setup on modular grid?

https://www.modulargrid.net/e/modules/home

That way you can get a sense of what sort of power draw the assortment of modules you’re wanting to use will require. It’s not always 100% accurate, so looking at the manuals to verify power requirements is always the best practice. And like @DesertMuseum mentions, the Make Noise power system may not be the best choice for video modules. However, I did use one for awhile and it was passable for my needs at the time. Good luck in your search!

#44 — VideoFanatic · 2018-12-12

Hi there, thanks so much for the feedback. The Thing is I am looking for a 104HP 3U row with he right kind of power. About £300, anyone know of anything like this that is good for video? Many thanks!

#45 — VanTa · 2018-12-12

Im looking into the Befaco JumpSkiff, mostly because of size (98HP, 52mm deep), which will be ideal for Orion.

The topology of the power supply should be fine for video, but it has only 0.6A.

Extra hole to power the fpga with a second brick? Bigger brick?

Anyone experience with it?

VideoFanatic, what you can also do is to get a moog mother case or similar that comes with no power and fit any of the PSU recommended by Lars.

#46 — cinema.av · 2018-12-25

Hello, in the last week I’ve upgraded my main live-performance case from a 6u bento-box with a synthrotek deluxe power w a 5a meanwell supply, which could easily fit castle/cadets, to get this; a enclave 6u w a make noise bus and 4.3a volgen supply. while not a complete upgrade, ive notice zero change-over in terms of power and Ive got more modules in the enclave than on the bento.

however, if yr trying to fit castle/ cadets into a skiff like ive now got, try buying longer screws from yr local hardware store and mount a set of nuts between the bottom of the module and the edge of the rail. depending on the depth, you may need to apply 2-3 nuts. the ramps I have there only uses 1 set of nuts and barely fits in the deepest end of the case, but it’s enough space.

#47 — reverselandfill · 2018-12-25

what type of Volgen powersupply did you get? (and where did you buy it?) I’m looking for a new one too.

#48 — cinema.av · 2018-12-25

#49 — cinema.av · 2018-12-25

for the record, that is the power supply that ships w the new make noise steel cv bus cases.

#50 — a_digital_index · 2019-03-17

Another case inquiry. I seem to remember that a lot of early LZX systems were housed in Monorocket cases. Is it safe to say their power supplies were generally suitable for video purposes. I do believe they were linear.

#51 — creatorlars · 2019-03-17

Their linear supplies worked great (IIRC, the 6U case had enough power for LZX but 9U case that had the same PSU needed some augmentation.) There was a period when they were using Meanwell supplies that were not so great. I’m not sure what’s being used in them now.

#52 — a_digital_index · 2019-03-18

I don’t think they are made anymore. Still in search of a good 9u Utility case with sufficient power.

#53 — joem · 2019-05-31

Anyone know how well Trogotronic’s power supplies work for video? They’re pretty high amperage for sure, and they claim to be very clean power, but has anyone tried them out?

#54 — jkbh · 2019-07-16

Has anyone tried putting the Malekko power in a 3u 104hp case? From the specs there should be enough room, but I’m not quite sure if it will be to tight with cables and all.

I’ll want expand to two rows in the future so it would be nice to invest in a good power supply from the beginning.

#55 — creatorlars · 2019-07-16

3U full of LZX modules would be too much. Malekko Power is suitable for up to 208HP. Budget about +/-10mA per HP for LZX systems.

#56 — creatorlars · 2019-07-16

Have had terrible reports about switching noise from the Trogotronic.

#57 — Agawell · 2019-07-18

@creatorlars think you’re mixing up 3u and 3 rows here

@jkbh - as lars said it’s good for 208hp, it’ll be fine for 104hp

#58 — creatorlars · 2019-07-18

Yes, you’re right, I meant 3x 3U rows. So with 104HP rows, that’s 312HP. Recommended you power this with two powered boards supplying at least around 1.5A each.

#59 — GijsvO · 2019-10-05

MDLR are using a different power supply now and are no longer offering the Doepfer PSU3 option. I just got off the phone with him and he said the new power supply for the Performer series Pro (Meanwell GSM60A18-P1J with MDLR PWR 45W powered buss boards) is actually less noisy than the Doepfer. Can anybody confirm that this is a good choice for video synthesis?

And what would be a good ‘torture test’ to check the suitability of a modular case for video?

#60 — GijsvO · 2019-10-05

I see now that with only 1.2A on the -12V rail, like the Doepfer PSU3, it would be a bit light for 208HP anyway

#61 — joem · 2019-10-19

I’m looking for an acceptable power solution for 2 rows of 42hp of LZX modules. By the old 10mA per HP rule, that works out to just 840mA per rail, I believe. Though based on example configurations I’ve put together in modulargrid, it likely will actually need less than 600mA per rail no matter what configuration of modules I put in, so dipping a little below the 840mA spec should be OK.

Since it’s a smaller case, the size matters. The internal measurements are roughly 8.5" (216mm) wide by 10.5" (267mm) tall, which rules out both the Malekko Power and the Zeus Studio Bus. The Doepfer A-100PSU3 technically can fit, but I’m a bit concerned about the space it’ll take up (less possible depth for an entire row) and the possible heat it’ll generate, given those big heat sinks. I’m making the case myself, so I can make the depth whatever I want, but I’m also hoping to make it as shallow as I can while still housing some Cadets and some Expedition. I think a good size would be one of the power-supply-in-a-module ones which I can make a spot for in the side or back of the case (to save on HP), like a 4ms Row Power or Tip Tip uZeus, but are any of those adequate for video? (I’ve seen mixed comments here about some Row Powers…)

Does anyone have any suggestions? Has anyone tried making such a tiny system before? I guess I’ll settle for not-quite-ideal power cleanliness as long as it’s not terrible, since it looks so far like that might be my only choice.

#62 — nerdware · 2019-10-19

PSU modules like Row Power will likely be too noisy for use with a video synth. Maybe the Intelligel 30W PSU will work for you? I have no idea how clean it is but I’d be disappointed if it wasn’t an improvement over a power module. Another option might be an external PSU. Maybe a Doepfer in another box?

#63 — nerdware · 2019-10-19

BTW, the Row Power 40 is definitely too noisy for me to use with a video synth. Not recommended at all!

#64 — Agawell · 2019-10-20

Not sure how clean they are but befaco do very low profile power solutions (excalibus and lunchbox) the lunchbox might fit - I’m intending to build an excalibus as my next power supply and test it - but that probably won’t be early next year sometime - I’d be interested if anyone else has tried these power solutions - are they too noisy?

another possibility would be to house the actual PSU (say the PSU3) in a separate case and run the power to the case/bus board (addac are/were doing this)

#65 — joem · 2019-10-21

From the schematics, it looks like those two Befaco options use the exact same circuitry, so I’m very interested to know how your Excalibus tests go, even if it’s after I’ve made my case.

#66 — trbsnd · 2019-10-24

made the same experience as @nerdware , im using a row power but its somehow noisy. Not that big problem for me atm because my modular is paired with glitch-hardware but i want to improve that in future… hope the malekko power will be avaiable again soon… or i will go with doepfer

#67 — nerdware · 2019-10-24

Yeah, I made loads of glitchy feedback videos on Row Power. Its less noticable there, and maybe even a little useful, but you don’t have any choice in the matter. You get the noise whether you want it or not. Now I do not want it. YMMV.

#68 — trbsnd · 2019-10-24

what power solution do you use now?

#69 — nerdware · 2019-10-24

My main cabinet is a 12U rack and uses a pair of Malekko PSUs. I’m currently waiting for more to arrive in the UK so I can power a second cabinet. However, I have some LZX modules working well in a Mantis case. When I have the money and the one shop in the UK that sells Vessels gets a new shipment, I can buy one and move the modules from the Mantis to the Vessel.

#70 — trbsnd · 2019-10-24

ok thx, hope i can pickup a Malekko one here in germany soon

#71 — giantmecha · 2019-10-24

Hi - I use my Row Power 40 with a LIBB and it’s super clean!

http://www.genusmodu.com/products/libb.html

#72 — jevergreen · 2019-10-25

Does anyone have a visual example of the noise that you’re talking about, from whatever case/power situation? I’m trying to assess how much my LZX setup is afflicted by this. I’ve been using a Make Noise skiff and haven’t had any complaints so far, but maybe I’m just not seeing what you’re seeing.

#73 — trbsnd · 2019-10-25

i will check out the libb, but its also not available here in germany for now

for me its not really noise, more some kind of small edges i would say… the shapes are not 100% smooth, hard to describe…i will make a visual example when i have some time. But i also have trouble with crosstalk between some audio modules

#74 — trbsnd · 2019-11-10

attached my kind of noise in closeup

#75 — nerdware · 2019-11-11

That’s the kind of noise I was seeing on a Row Power 40. Thanks.

#76 — jevergreen · 2019-11-11

Thanks! @trbsnd

I’ve started to notice a similar thing as I’ve been pushing things further (more cross modulation, finer limits; using power from a Make Noise Skiff). I think someone mentioned elsewhere that they notice it most when keying, and as I was listening to one of the Vidicon talks on YouTube, where the fellow from Mystic Circuits mentioned that signal to noise ratio is one of the challenges when designing video instruments. Described that way, the noise thing started to make sense, so I thought it would be good to share here.

Does anyone know, are digital modules (Orion series, etc) effected by background noise in the same way, or to the same degree? Or what about this, if two different power supplies are used (one clean, the other noisy, modules patched together) would the noise only effect part of the signal path, or would it effect all the modules on both power supplies?

#77 — nerdware · 2019-11-11

I’ve mixed modules on clean and dirty PSUs, and my experience is: once a signal becomes dirty, it stays dirty. I’ve now moved all my video modules onto clean power (Malekko and Mantis). So only my non-video modules are on the dirty power now.

I can’t comment on the Orion series as I don’t have any yet. Nor can I comment on Structure, but like you, I’d love to know how well (or not) these modules cope with noisy power.

#78 — Halfgeleider · 2019-11-13

Hi there,since im newer than the newest newbie, (first post) but does anyone have experience with L1 power supplies? Im planning on a power supply switch in my euro rigs and plan to take a plunge into video synthesis.

Thanks in advance

#79 — SPIKE · 2019-11-23

hey ya everyone!

i finally joined the forum after delving into vid noiz quite a bit recently.

i posted elsewhere asking for insight to installing a Memory Palace and was pointed here by @337is.

below is the current design i am formulating on ModularGrid.

looks like i will need to update the powersupply from an Intellijel TPS80W Triple Power Supply - 80W 3U / 6U busboard.

the case i am trying to re-purpose is an old 6U Enclave case and some older modules that i currently have.

in fact…

i have everything except the second Structure and the Memory Palace.

is there anything else anything you guys can see as a potential problem with this design?

(other than the price)

thanks for any and all help!

#80 — csboling · 2019-11-23

Interesting setup, I’m curious what your intended signal flow is like with the second Structure. As far as I know all of Structure’s outputs are composite, are you planning to use each one to drive a different display?

With the Memory Palace I would probably like some more 1V pattern sources or camera inputs. Processing still images is awesome but working with live video input (or both input and stills) is IMO where the Memory Palace really shines. Especially with the alpha input!

#81 — SPIKE · 2019-11-24

all that vid signal will go to a Roland VR-3EX and a BPMC modified Edirol V-8 so i have tons of vid routing capabilities.

i am approaching this with a CV and Gate control kind of focus and not so much with the 1v vid standard.

at least…that is how i am using Structure and the DU NTSC.

lot’s of syncable LFOs and other rhythmic controls moving in time with all of the noiz is what i am really interested in.

lately i have been using a Little Deformer 3 to do all the heavy lifting with it sending synced CC messages and CV control that all moves in perfect time.

my current vid noiz setup consists of Structure in a 4MS 48X pod, Edirol P-10, Korg Entrancer, BPMC V-8, VR-3EX, C&G ETC and three C&G videoscope/rhythmscope thingies.

hmmm…

now you have me rethinking again…

that poor DU-SEQ has been kicked out of three cases now!

thanks for the insight!

here’s a link to a lot of my recent visual noiz…these are all live streams as of late: ASTROGENIC HALLUCINAUTING - late night noiz for late night fiends

I think with outboard video mixing / processing well covered and complex composite sources like Structure, another incredible range of stuff to explore is video feedback. Memory Palace works fantastically in a camera feedback loop. For decoding composite signals the best options would be TBC2 or one of the upcoming Automata series. One or more Cadet IIs could also work, though each of those would also be a mono feed, and would probably be a more complex sync situation.

#83 — SPIKE · 2019-11-24

Neat!

Would that upcoming Chromagnon be a good candidate for vid input?

#84 — csboling · 2019-11-24

Yes, I believe the plan is for Chromagnon and the other upcoming Automata instruments to decode full color composite input. Can’t recall if I read that here or on the LZX Facebook group.

#85 — VanTa · 2019-12-12

Price and full specs yet to be announced.

How does that power supply look like?

#86 — transistorcat · 2019-12-12

Someone in the MW thread claimed to have seen a spec of “3 zones, each of which can provide up to 1 A of power”

If i remember correctly, the model D fills 70 hp, so 2*70 x 2 rows -> 280 hp.

If this is a proper 1A on both +12V and -12V, this does deliver more than the magical 10 ma/hp

I guess the question comes down to the big ifs and then how clean the power is.

#87 — catbiscuits · 2020-01-02

I already have a PS3 Doepfer P9, but as it gets filled with LZX modules, I am aware I will run out of power fast.

I was thinking of adding an extra power supply for one row. My thought had been that I could get a Row Power or Microzeus, unplug the connectors to the passive busboard and feed it that way, but I’m reading here that the Row Power would be too glitchy and am thinking the Mantis might be too. Any ideas? Also, any thoughts about unplugging the bus board to pass the power?

#88 — nerdware · 2020-01-02

I recommend the Malekko PSU and the TTA Access module. I’m using a Dual Access to power two Malekko PSUs in a 12U rack cab. I needed some help mounting the PSUs, however.

If you use this PSU, check you have some Faston 250 connectors and a crimping tool. I had to buy mine for the job, but that was easy.

Now I have a full set of various Faston250 connectors, so I can make all kinds of funny internal power cables.

#89 — northerntao · 2020-01-02

I just bought a Doepfer Monster base to upgrade the 3 Happy Ending Kits I’ve been using in a 9U “bento” flight case from Black Market. I’ve though about putting a Malekko board in the flight case - I’m not that much of an electronics or DIY guy, but it seems pretty easy to mount the Malekko if you have the right tools. I was thinking I was gonna have to punch holes in the case for a switch and DC barrel, but I like this solution better.

#90 — catbiscuits · 2020-01-02

That looks too complicated for me, looking for an easier solution. I’m wondering is some modules might care less about power supply than others (Liquid TV? Bridge?)

#91 — nerdware · 2020-01-02

Maybe Liquid TV, esp if you use the 12V DC socket on the back. I’ve yet to try that option as I’ve been happy powering it from first an RP40 and now a Mantis case/PSU. I’m still evaluating the Mantis PSU. It’s a big improvement over the RP40, but I’ve yet to test it to its limits. I should try an A/B keying test. Keying tends to expose noise rather well, I find. (E.g. A=Mantis/B=Malekko.)

#92 — nerdware · 2020-01-02

Consider this recent video: https://vimeo.com/381878754. Is there some small noise in there? Did it come from the Mantis PSU, where the ramps are generated? The keying was done by a Doorway on the Malekko PSU. The ramps come from a Diver and a VC in the Mantis case.

#93 — catbiscuits · 2020-01-04

Ugh, so according to modular grid, I’m definitely overvoltage on the -12V range and that’s with some of my modules having incomplete specs.

I’ve purchased a A100 base. I’m going to take my PSU3 P9 and split it between an older PSU2 P6 and the PSU3 P9. That should work, right? The PSU2 won’t matter since the 1200V on -12 has been the limiting factor thus far.

I know @creatorlars and everyone else is super busy, but there are some power specs missing from Modular Grid, for example for the Cadet Ramps.

#94 — joem · 2020-01-05

The general rule of thumb for LZX modules is to plan on needing 10mA per HP. Since the Cadets are all 4 HP, it’s fairly safe to assume that they’ll need around 40mA on the +12V and 40mA on the -12V. The actual numbers vary, but more often than not they’ll be less than 10mA per HP.

#95 — trbsnd · 2020-01-06

i measured my cadets some weeks ago with the joranalogue test3, i remember some of them consumed more mA than indicated by modulargrid

#96 — nerdware · 2020-01-07

The problem I’m currently wrestling with is how to cleanly power my next cabinet. A 12U 19" rack cabinet made of steel.

I really like the Malekko PSU but mounting that on a steel panel is way beyond anything I can imagine, nevermind build. I can’t even buy the power bricks Malekko recommend thanks to CE restrictions. A shop could sell me one, if any shop here sold them, but of course they don’t.

I can’t even be sure I can buy a Malekko PSU in the UK. I know of two shops who might. One has in the past, but this PSU is currently out of stock. The other shop talks mysteriously about not having stuff in stock, but being able to solve that in just a matter of days, with a vague reference to distributers.

So maybe the ideal PSU for me would be a small board that plugs into the power socket on the back of a module. On the other side could be a 12V DC socket and the circuitry for a single-module PSU. Maybe 300ma on each rail. If that existed, I’d buy a dozen without hesitating. Esp if it’s not fussy about the power brick. I.e. vapourware.

I could just abandon the cabinet idea (and sell the modules I have that require a cabinet due to depth) and switch to Vessels. Then I’d be limited to a maximum of 4 Vessels (2 horizontal, 2 vertical). That’s 2 x 204hp x 4 = 816hp. With cabinets using the same tablespace I could still have room for 2 Vessels.

My cabinets are elevated on 3U cabinets, giving me space for extra gear under the synth, but also making it easier to use skiffs in front. That would be 84hp x 4 x 3 = 1008hp just for the cabs. The 2 Vessels in front would add another 416hp.

So, I’m very pleased to see new modules like Topogram and the forthcoming Automata series.

#97 — Dewb · 2020-01-07

Mounting a Malekko Power on a sheet-steel panel isn’t hard. Assuming you’re drilling holes through, it’s easier than trying to anchor pocket standoffs in a wood case.

All you need is a hand drill, a half dozen machine screws and nuts, and 1/2” spacers. Malekko supplies a drill template in the documentation but it’s unfortunately not to scale and not downloadable to print at scale, so I made this one. If you can print it on 11x17 paper all you need to do is cut it out, tape it on, and use something sharp to tap divots in the hole centers before you drill. (There are a lot of holes, but Malekko docs say you only have to use the six marked with red arrows below.)

EDIT: I can’t upload a PDF, but here’s a PNG:

Fusion drawing link: https://a360.co/2WLE4Pq

#98 — nerdware · 2020-01-07

I can’t do any of that. Trust me on that. I know my limits. That’s way over on the “I can’t do that” side.

#99 — joem · 2020-01-08

Might be worth it to find someone who can do it for you, then. It’s a simple enough task that anyone who owns a drill can probably manage it, so no need to draw a professional into it unless you really want. Just ask a friend.

#100 — Gavin · 2020-02-28

Would folks like to share their experiences with wider cases - 126hp or 140hp? It seems the 10mA per 1hp rule means power per row gets trickier (or at least expensive) at these widths, as 1260 or 1400 per row means one PSU per row? What solutions have people found work for them here?

#101 — souka · 2020-02-28

Could you please share more info on your setup?

Malekko has been out of stock for a while and the genusmodu stuff looks like a good alternative to it but i couldn’t find as many people using it. Using the Row Power 40 would also help with the fact that I wouldn’t have to create holes for the power supply in the case as it would power from the front. Do you feel that it provides enough power for your system? I’m going for a 6U 104HP and +12V @ 1.5A, -12V @ 1.3A, +5V @ 1.5A might not be enough.

#102 — Agawell · 2020-02-28

you may be okay with that

but, it’s not just about is there enough power - is it clean enough too - most eurorack psus are fine for audio, but a lot have issues with really high frequency noise, which can affect video - this is why the latest modules (at least topogram and chromagnon) have on board power conditioning - so they can cope with noisier power

I would mock whatever you are intending up on Modular grid and see - if you are intending to rack some of the newer modules then pay attention to what can be powered from an adapter (say if you have a Memory Palace and a Chromagnon) - there is a module due to allow power input for these from the front of the case - so no cutting involved

#103 — lumena · 2020-05-11

Hi all,

I am wondering if anyone has actually tried the power from MDLR cases. I am thinking of ordering a case and I am wondering if I will need to take steps to fix power - their power supply looks really hefty but I am asking for experiences.

#104 — souka · 2020-05-15

I’m in the process of ordering the 3.4A model of the Bel Power Linear Supply as suggested in this post by Lars — [/forum/

I have decided to go for the best quality possible sacrificing on the portability factor. I’m going to design an external case for the power supply and a separate one just for the modules.

As far as my understanding goes, LZX series modules use only the +12V and -12V rails so a 5V scenario doesn’t need to be included for now.

I’m thinking about having three of these in total (see image below). The first one would be used to connect AC and the power supply case. The second and third one between the power supply and the modular case.

https://pt.mouser.com/images/schaffner/lrg/FN9262-1-06_series_DSL.jpgI’ll probably be working on this the following months. I intend to share some of the process by the end of it.

#105 — jnoble · 2020-05-15

This is for AC power entry. Do you intend to run DC through them? If so, you are creating a very hazardous situation since it would be easy for someone to plug AC mains power into an input expecting low voltage DC.

Perhaps I misunderstand your intentions.

#106 — souka · 2020-05-29

You understood correctly and I appreciate your feedback very much.

I have, since posting above, investigated a bit more and arrived to similar conclusions to yours. I thought that color coding connections and cables, along with careful case design would be enough but, as you put it, it is too vulnerable to mistakes. I also had trouble finding a cable that would feature female connections on both ends so it was prone to be redesigned anyway.

Do you know any type of cabling standard that would be adequate for connecting the powersupply module and the eurorack module case?

A simple representation of the system.

If you’re sending DC through this, then perhaps 4 pin XLR would work well. It can’t be confused with anything else and has more than adequate current capacity (10A per pin, use two for ground and one each for the +/-12V rails). Something like a Neutrik NC4FXX on the cable and NC4FD-LX in the case might do it.

#108 — LauLindqvist · 2020-06-10

I use cheap 4 pin m12 connectors and cables for interconnecting power between cases…

Found cheap ones via aliexpress can send link later…

#109 — diemangonel · 2020-07-13

I’m shopping for an eurorack case and although I don’t own any LZX modules yet, they are kind of on my roadmap of purchases in the mid-long term, so I’m thinking about getting something that would work with those as well.

Would a Cre8audio Nifty Case work OK-ish with LZX modules? I know that the PSU will be noisy and I’m somewhat concerned with the low performance of the -12V rail, but is there anything else I should keep an eye on?

Thank you!

#110 — Agawell · 2020-07-13

have you looked at the recommendations??? - that’s a good place to start!

I’ve never seen anyone mention using the nifty case for video - so you could always try it!!!

good (recommended) power supplies are the Malekko, Doepfer PSU3 and TipTop Studio bus - if you get a doepfer case specifically for video - 6u is recommended - as the 9u has more space and the same power supply

I use a tiptop mantis which is very close to the Studio bus and works well - but can only really get half full of LZX modules - I have some doepfer and Maths and Stages in the same case and everything just about works - unless it gets hot - which is when you discover why the vessels have fans in them!

saying this which modules are you interested in?

some of (if not all) the newer ones are less fussy about power (on board regulators) Toppogram for example and both Chromagnon and Memory Palace can be (at least partially) powered from an external wall wart which will help massively

and a some of the DIY modules will probably not fit in the nifty

#111 — Genlok · 2020-07-15

What are people doing for large systems? I’m looking to purchase a 12U MDLR case because my video modular is just exploding all over in different cases, all with substandard power.

Lars has said in various comments that the Malekko and new LZX boards aren’t ideal for large studio systems. So what is?

LIBB+linear PSU would be the highest quality option, but finding a power supply that will output up to 6A and fit inside a eurorack case is a bit challenging. There is the L-1 but at only 1.5A I’d need four of them and that just feels a bit overkill-ish or something.

Curious to hear what others are doing!

#112 — jwsmithwick1 · 2020-07-15

I have an MDLR 14U case that is fantastic from a header and wattage perspective. I haven’t experienced all that much noise with the Meanwell power supplies either. I have limited space in my apartment, so it is nice to be able to stow all that hp in around 4 cubic feet. My one concern is that the ring/collar isn’t as solid as I’d like it to be for transportation, especially considering how heavy/not waterproof a loaded case can be. I could probably reenforce some of the weaker points, however I’d rather spend the time patching. I’d be lying if I said that I wasn’t considering a Doepfer case, especially because their power supplies have been recommended by LZX for low noise.

#113 — sean · 2020-07-22

After collecting parts piecemeal for probably almost a year, finally put together a case today — with a lot of help from a friend who is far more handy than I (my main contribution was slicing open my thumb while trying to shorten a screw).

Very close to what @Tan_Sat posted above, but with an extra 1u row as well. Used @Dewb’s drill template, so thanks for that!

Will post parts list below pics, in case that helps anyone.

Didn’t want to wait for the LZX power module, so just built this 1u Synthrotek power inlet kit:

Added feet, so the screws on the bottom don’t scratch tables:

Ended up using the same exact feet for the spacers on either side of the rack bracket since they were a perfect fit:

Harbor Freight Apache 4800 XL Case $55 Malekko Power $229 Cincon TRH100A120 DC Power Brick $45 Synthrotek 1u Power Panel $18 Vector TS169 Rails x 6 $66 Pulp Logic 1u + 3u + 3u Case Bracket $40 M2.5 Square Nuts $12

& ~$10 misc. hardware

= $475

(not including taxes and shipping, but I also picked up several of those things on sale or used, so I estimate my total cost was more like $450)

#116 — jeffbbz · 2020-08-27

So i’m doing a DIY Suitcase rack for my first ever set up, what is the recommended depth for such a case?

I’m looking to mount 6u 84hp to the bottom and then have room at the top to maybe leave patches in when its closed (although not a deal breaker). So how deep does the bottom where I’ll have the rails and power stuff need to be (right now, I’ve got cadets, syntonie, reverse landfill diy stuff only but who knows in the future)? Is there a general recommendation?

#117 — creatorlars · 2020-08-27

2.5 inches at a minimum I’d say. If you want to be careful then I’d go 4 inches or so.

#118 — Agawell · 2020-08-27

all the cadets and most of the synthonie and reverse landfill are boards mounted perpendicular to the panel and some of them can be quite deep so I’d say what lars is saying as clearance over the power supply/busboards and any mountings for the busboards - I’d go for at least 3 inches so there’s a decent amount space for ribbon cables too!

#119 — reverselandfill · 2020-08-27

the Matrix mixer panel & pcb are mounted parallel

I have to say, I love shallow cases. But I have none.

My main case is 10.5 cm deep (which is about 4 inches)

#120 — Agawell · 2020-08-27

I know Martijn!!! - I’ve built and am using both the triple function generator and matrix mixer often - I just couldn’t be bothered to go into that much detail…

#121 — Agawell · 2020-08-27

not sure If I updated, the befaco supply seems reasonably clean - I’ve passed video through modules in it without obvious ‘dirt’ showing up

#122 — n3wt15 · 2020-08-29

I see some mention of the monorocket cases, and some power is good and some is not, but dont see specific models of power.

I found a monorocket case with 2 Heng Fu HF60W-SL-12’s in it and was wondering if those would be good for a 12u system?

#123 — Agawell · 2020-08-30

generally if the power supply is not mentioned as being good for video - you will be taking a gamble

#124 — praiseofpeace · 2020-09-17

I want preface this question by emphasizing I understand that Chromagnon has it’s own power and Memory Palace has the aux 12V DC option, however there is something to be said for the convenience of having all modules in one case with a SINGLE power supply especially when it comes to performance applications.

In a recent comment on facebook Lars said of Chromagnon: “worth noting that this can be dirty power. All the clean analog power supplies are inside the module. So you should be able to use a much larger range of euro power supplies than with previous LZX modules.” Excuse my ignorance, but the word ‘analog’ caught my eye. Does this mean that more digitally oriented modules like Memory Palace would be less susceptible to dirty power? I am currently considering limiting the video modules in my system to the two aforementioned: Memory Palace and Chromagnon. Would this open up the selection of power supplies? Many of the sanctioned power supplies listed in this thread wouldn’t meet the demands of these two modules however something like Intellijel’s TPS80W would.

#125 — Z0NK0UT · 2020-09-19

You are correct–Memory Palace (with the other Orion modules) and Chromagnon are much better insulated from power supply ripple than the Expedition series modules. It is worth noting that Chromagnon will require almost 1.5A on the positive 12V rail, which will eliminate most eurorack power supplies as viable power solutions.

#126 — praiseofpeace · 2020-09-19

Ironically, if I’m understanding this correctly, this is great news: it leaves me with just under 1000mA of unused power, are their any other modules similarly robust

?

#127 — Z0NK0UT · 2020-09-20

Memory Palace needs about 550ma on the positive rail, so you should be ok.

#128 — proto · 2020-09-30

Just picked up the 84hp NiftyCASE and plugged in my Visual Cortex and Prismatic Ray modules. For some reason I get a high pitch hiss whenever I plug in more than one module. I thought I would be within the power limits:

Power output for modules

• +12V - 1500mA peak output**

• -12V - 500mA peak output**

• +5V - 500mA peak output**

https://www.cre8audio.com/niftycase

Does the case just come with a bad psu?

#129 — Agawell · 2020-09-30

it’s a definite possibility - I’ve not heard of whining before though

I’d go for a case with one of the recommended power supplies if I were you, otherwise it is a complete gamble - have you tried plugging into a tv? you’ll probably see noise all over that too

#130 — videot · 2020-11-11

hello! if i understand things, both the Memory Palace and the Chromagnon are best run with their own 12V power supplies in addition to the Euro buss power (for non +12v things)?

i’m helping a friend put together a pretty packed 208hp video rig. in my dreams, i would love to find a one-power cable solution. i wonder if i installed a second power supply to just feed the +12 needs of these two modules, if it could all run from a single IEC power cable to the case?

it’s +12v DC, i presume that these two modules need? what is the draw needed?

thanks very much!

#131 — wednesdayayay · 2020-11-11

chromagnon / TBC2 can be completely powered off a 12v input OR euro power

memory palace needs either just euro power or 12v plus euro power

a good place to look for info about the modules is the LZX website

chromagnon

memory palace reference card

memory palace is one of the modules which will be known as falling between the new power standard and the old.

the new powered standard is going to be one of those things that incoming video synthesists won’t even have to think about but will feel like magic to people who’ve been around for a while.

#132 — Z0NK0UT · 2020-11-11

Memory Palace requires about 550ma on the positive 12v rail and a little bit on the negative.

Chromagnon will be somewhere under 1500ma. There will be a 4hp power distro module to send additional 12v to modules that have barrel power inlets.

#133 — videot · 2020-11-11

that’s excellent info, thank you. i’m sorry if this has been covered in detial elsewhere - i couldn’t find it!

is there a projected date for the release of this 12v distro module? in its absense, could i simply take a brick like, say https://www.mouser.ca/ProductDetail/418-TRH100A12012E126 (12v, over 8A!) and split the output between the Memory Palace, Chromagnon, and the Structure (all of which will be in this rack, and all of which can use supplimentary 12v via barell jacks)?

i’m trying to find a clean, simple, 1-power cable solution to what will be a portable rig being used by various artists.

thanks so much, and again, sorry if this has all be covered elsewhere in the forum.

#134 — wednesdayayay · 2020-11-11

yes you can split the 12v power

I currently am taking the 12v aux out from my vessel into a splitter powering a row40 and a podx60

#135 — videot · 2020-11-11

alas, the Vessel [nice typo!] is no more, it seems. on the subject of cases, i noticed that the Vessel has two fans installed. is this advised for other cases?

#136 — Z0NK0UT · 2020-11-11

The power distro module will be released when TBC2 (which also has an aux barrel input) is ready to ship.

#137 — dni_br · 2020-11-23

I bought a new case. it s 12 U 84 HP.

The power is Synthrotek blue . 3a at +12v. so it respects the 10 mA per hp.

But it s so noisy.

Does anyone have experiences with that power ?

#138 — rempesm · 2020-11-23

I wouldn’t recommend a Synthrotek PSU (or any of their products for that matter–google Synthrotek controversy) for video synthesis.

Interested in hearing how people got their vessels portable or if you anyone made their own travel accessories for it like a snap on hard plastic dust cover(w enough room to close patched), using the bumper screw placement to mount a handle or shoulder strap, etc.

#145 — jwsmithwick1 · 2020-12-19

Maybe look for an MDLR header board. The ones I have in my MDLR case are solid. Also, the Doepfer PSU3 has gotten the highest praise for its power filtering (sharper lines). That combo of MDLR board and Doepfer PSU might work best for a DIY setup if you can’t source a Malekko board.

Are the power supplies in ADDAC cases unofficially recommended for LZX modules?

I was looking for rackmountable cases and came across this Video Circuits FB post it seems that they are sufficient.

Definitely, it solves most issues presented above in this thread and you never really have to worry about available stock–just print some! I’m working on getting my system all swapped over to Capsule power. Might consider offering some built extras or finding ways to make the potentially scary bits of SMT on it (QFN regulators) not so troublesome but don’t quote me on that yet.

#151 — joem · 2021-06-18

Those QFN bits are the only thing stopping me from making one or a few for myself.

#152 — wiatrob · 2021-06-18

The ideal solution would be to have the QFN parts soldered by the PCB fabricator.

#153 — rempesm · 2021-06-21

Agree that would be easiest, I’ll have to check if JLCPCB has both regulators in stock. All the other parts can easily be placed by hand with a soldering iron and flux. After putting together 10 of these by myself though (just missing DC jacks

), I can confirm regular ol’ human beings can do it with a hot air tool, flux, ChipQuik low temp solder and a fair amount of patience:

Preheating your boards is a very good idea and I used an integrated PCB preheater / temperature controlled hot air gun stand.

I found this video to be a helpful reminder on key points of QFN soldering with just a hot air tool and flux:

The ones in this batch of 10 are already spoken for but I may do a run of 10 or 20 fully built units if enough folks would be interested. I don’t want to clog up this thread and I don’t have an exact price figured out quite yet so please PM me for now if you’re interested.

Wow! Nice work! The smallest pitch I’ve tackled recently is TSSOP-16. You hit on the one element I lack: PATIENCE

Question on the DC Power Distro DC Distro – LZX Industries

Is one DC Power Distro sufficient to power one each Memory Palace, Chromagnon, TBC2 and Expander?

#159 — vhsdestroyer · 2021-08-07

I believe its around 5amps so probably more

#160 — Z0NK0UT · 2021-08-09

DC Distro gives you 5A to work with.

Chromagnon is ~ 1.5A

Mempal and TBC2 are ~ .55A each

So I am planning to build another case, similar to the one I posted above. But, factoring in a bunch of power-hungry Gen3 modules, I want to make it a hybrid case, power-wise.

I am trying to balance a number of factors here: portability, durability, maximizing space for modules, as well as admittedly also being budget conscious.

For DC distribution, I was thinking of using the distribution blocks that Dubpixel posted a while back:

amazon.comhttps://www.amazon.com/OONO-Position-Terminal-Distribution-Module/dp/B08TBXQ7H6Buy OONO 16 Amp 2x12 Position Terminal Block Distribution Module for AC DC: Control & Power Supplies - Amazon.com ✓ FREE DELIVERY possible on eligible purchases

Link: Amazon.com: OONO 16 Amp 2x12 Position Terminal Block Distribution Module for AC...

And then for eurorack power, I was thinking of using a TipTop Studio Bus, as I recall that being mentioned in the past as a reasonably low noise board, it provides enough power for the non-Gen3 modules I’ll have in the case, while also being still readily available and relatively inexpensive.

BUT, because nothing can be easy, I now see that the Studio Bus requires 15v power, and not 12v. Yet I was hoping to have a single power brick that would be connected to both the eurorack board and the distribution for the Gen3 modules.

So, questions:

1. Is there another eurorack power board that folks can recommend, with similar performance to the Studio Bus, at a similar price point, but that is 12v?

(I don’t know of any) (BSO’s recent run of Capsules comes close price-wise, but I guess I missed that; also it does not do as good a job of physically distributing the power jacks, which I think would frustrate me)

1. Or is a dual brick solution the easiest/cheapest here?

(I would however really rather avoid this, if possible; but if it is the path of least resistance—

) 1. Is there some other solution I am not thinking of?

(…More generally, what are people doing for DIY hybrid cases?)

Thanks for any thoughts/input!

#162 — sean · 2023-01-22

…But, alternatively, does anyone have a single built-up LZX Capsule power board available?

#163 — Rik_bS · 2023-01-22

Dual PSU - get in line, not wall warts. Tape them together, use an IEC Y splitter and you’ll barely notice inconvenience besides two cables and possibly extra bulk

#164 — creatorlars · 2023-01-23

Dual PSU is the best answer (2 bricks.)

But also, you can get 12V to 15V boost converters like this one:

amazon.comhttps://www.amazon.com/Step-up-Converter-Regulator-Waterproof-Transformer/dp/B097GS4LNWBuy DC DC 12V to 15V 10A Step-up Module,Boost Converter 9V-13V to 15V Voltage Regulator,Waterproof Power Adapt 150W 15V Volt Transformer Module(12V to 15V 10A): Power Converters - Amazon.com ✓ FREE DELIVERY possible on eligible purchases

You could try powering the TipTop from that, and then have a big hefty 12V source for everything on a single inlet (just make sure to rate connectors appropriately.)

Posting to see if anyone has any recent experiences/updates with the following:

• MDLR PWR powered busboard 45W version
• Konstantlab Boardpower (45W)
• Make Noise Powered Busboard

Looking between the Submodular Systems ‘Shadow’ and the MDLR cases (Pro & Mk1)

Additionally, if anyone has any experience with those specific cases please lmk

#166 — vhsdestroyer · 2023-04-11

MDLR 45w & 85w worked fine for my SD rig. Sold that case before the HD encoders launched so cant say much about that.

#167 — Agawell · 2023-04-11

I’d check on other forums (specifically modwiggler) for news on MDLR - iirc they’ve gone AWOL - but please check as I might be wrong

#168 — Pagoda · 2023-04-12

Konstantlab Boardpower

Was the best option I had before switching to 3A distros.

I am currently running 2x 3A distros in a Makenoise case with a few VH.S modules, Sensory Translator and Pams are on the MN bus. Running nicely for me.

Im a fan of Konstantlab. I run a few euro cases with it and all my Serge stuff runs on 3 Cihla’s. They have a filtered section on each of those Boardpowers. Not sure if it helps or not? They also just released a bigger euro setup. My euro cases were built by Blackhole cases

Solid folks making a real nice case.

#169 — sean · 2023-04-13

For anyone that happens to be following along from my question/discussion a few posts back, I decided that grabbing a Capsule was the path of least resistance for my new dual-power case.

So, here is what I ended up with:

Very similar to the other case I built, above, but instead of the Malekko Power I am using the Capsule plus a 12v distribution block that Dubpixel had pointed out a while back. (Haven’t plugged everything in yet, but seems to all be working thus far after testing with a few individual modules.)

And I decided I didn’t want to give Synthrotek any more of my money, so the person who helped me put this together just cut a little panel for a power inlet and switch.

#170 — Jesse · 2023-04-13

If anyone needs we’ve got a handful of Capsules that we’re happy to pass along cheap

[edit] they gone

I mean we have more but we’d have to build em, so we can make it happen just don’t expect us to ship em tomorrow

#171 — Pagoda · 2023-04-14

Nice work Sean!

I don’t know why more modular heads don’t go with these for cases. Always feels so obvious of a choice if you want to transport. What model did you ues? Or is this a stock Synthrotek sans power? I have spent ages on a few case websites working out the best dimensions but can never decide what to go with.

Edit: looks like the same Apache listed above yea?

#172 — sean · 2023-04-14

Yes, it is another Apache 4800 case from Harbor Freight. Those are the best balance of size, ruggedness, and cost that I have seen.

Another reasonably-priced option that someone either mentioned here, on Discord, or that I possibly saw on Modwiggler (I forget) is the Explorer 5117, which fits 6u and ~100hp.
