“ A NOTE”A quick note I possibly didn’t make clear! The power jack isn’t 240 volts! That would be crazy. It’s wired to a 12v ac wall wart. There’s a link in the description to it!
As an electrician if you hooked up 240v or even 115v US to those power supply boards, you would get a capacitor fireworks display you would NEVER forget 😯 DON'T PLAY AROUND WITH POWER OUT THE WALL KIDS IT WILL!!! KILL YOU
Are AC wall - warts or transformers a whole lot harder to come by than DC? I have seen maybe two schematics online for making a bi-polar supply from a D.C. Wall wart, because they're more common out in this here New World. AC are much less likely to be found. So your voltage regulators on your Freq. Central PCBs, they're rated for a good 1 - 1&1/2 Amperes per regulator, no? So maybe a good idea to take note your regulators' current capacities in Amperes when matching the AC wall warts for them. If your wall wart is able to provide 5.5 Amperes of current, then you should probably make allowances by wiring two of the regulator PCBs to the single wall wart (so to use its current capabilities efficiently). By using different values of fuses for both rails, I've learned a whole lot about power consumption. If you're modules need a total of 450 milliAmperes of current, I'll put a 600 mAmp fuse on it, so it won't allow too high of a current spike. More modules, I put bigger fuse. So I've learned that my fuse should reflect my power consumption needs and not just to put the largest fuse that my wall wart would allow! Since maybe I only need 1/2 of my wall wart's power capability. Any thoughts / feelings about the donut shaped Toroidal transformers vs the cube shaped varieties? You are really doing great, Thank You!
You are going to freaking bust your equipment Sam we have a gig coming up remember? FANS PLZ DONT GO :'rjfjrhfjdkcmdnjjhhejfnfhjfje OK ITS ANNOYING PLS DONT SAY HI DONT BURST MY FUSE U 3 YR OLDS PLZ NO ATTACK PLEEEEEEEEEEEZ XD
Sam, I gotta say this is just about my favorite content on UA-cam at the moment. You are clearly smart and motivated as hell, and you are enabling aspiring makers and musicians to deepen their craft. You are helping remove financial and mental barriers for people with this channel, and the world needs as much of that as it can get. I can't wait to see what's next.
'Tools are made to be used not to be pretty, even though they do look pretty in their own kind of brutal way' 'No need for measurements because, measurements, we all know, are for crazy people and mathematicians' Nowhere else can I find such peculiar maxims, keeps me coming back here.
Just made an OSB-version of this for only 20 bucks worth of material and it's huge. Expected it to be less easy / way more prone to critical errors. Thank you for yor content. It can be pretty encouraging.
This video brings up great memories of when I first got into synth DIY and I watched an MFOS video on building a case. Thanks Sam for continuing to push synth DIY to the masses! i'm sure Ray would be proud!
I want a t-shirt that says "Mesurements are for mathematicians and crazy people" I was looking for inspiration to build my modular synth. Thanks for you awesome drive !
I was waiting for this series since ever!!!! I want to build a DIY-Mudular by myself and now I'm getting 'help' by the Master of DIY-Modular... I love your content!!!!!!
Let me convert the measurements to US: Depth: 1/3 of a foot Height: 3/8 of an arm holding a budweiser Length: the wingspan of a young american eagle. You are welcome...
For the three remaining backwards countries on the planet that still us the Imperial measurement system (Liberia, Myanmar and the US) the conversion factor is 1 inch = 2.54 cm
You can use screen window framing pieces for the rails as well. It's very inexpensive (about $4 US for a 7ft length), doesn't splinter when you screw your modules in, and is almost the exact same size as a legit pre-drilled Eurorack rail. Once you get your rails into your case just slap the module into the rail space, mark the holes with a permanent marker, use a 2mm bit to drill holes, then screw your modules right on it. It'll be sung the first go, but the screw will tap your hole as you screw it in since aluminum is soft. Hope you enjoy this tip!
If anyone makes similar make sure those PSUs are wired all in phase! It doesnt matter which you connect if you have one psu board but if you have multiple connected to 12v AC they must be connected in phase
I still can't understand how this circuit works without a transformer... Reactifying bridges, caps and volt. regulators? So is it a rough version of a linear DC supply?
MoolahNasreddin I think it probably is a charge pump. These invert a DC voltage by periodically charging a capacitor with the input voltage and then connecting the positively charged electrode of the capacitor to ground. Then another capacitor is charged from the negatively charged electrode, which now is below ground by the input voltage. I don’t know if this explanation is good, maybe you should look up a circuit diagram.
Dude, you're a fucking national treasure. I don't know jackshit about this stuff, but you make it interesting to watch and your passion is contagious. You seem like a down-to-earth and chill dude... had me totally cracking up at your simple "AC current, you know, the wavey one?" Keep it up man! You rock!
Johnny Cogs yep! It was always intended to be a video! But I didn’t really know how to achieve a video like this last year. Without it dragging way too much. So hence it being a zine! But now it’s a vid 🙃
I always build my Kosmo cases with backs that can flip open. Held closed with magnets. But I guess for touring that would be too fragile. I mount the power bus system on the floor of the case instead of on the back. I love the way you put these cases together Sam. It's so simple and yet so practical.
You cheeky bugger. I just got myself a power supply yesterday with some eurorack rails. It is my first modular and can;t wait to begin making my own modules. Let the building begin 🤘
Awesome video Sam! I would add some little metal latches on the sides of the cabinets so they lock in together when they're set up. It'll cost you practically nothing, too. Keep it up 👍🏽
I'm excited about this series! Till now I didn't try any modular stuff because I thought it would be too complicated, but this sounds like it could be easy enough for me.
Pretty cool units and very useful. Just a thought - if you drill a few holes in the top to line up with the rubber feet then they will lock together a bit better. Glue some blocks on the inside then to seal up the holes...
I'm going to have to plug the smoke alarms back in. ATX standards look like they might be more complicated to track than I remember but I really want to reuse and recycle. I deliver papers at night and pick up a lot of roadside goodies but my house is filling up with half finished arcade machines made from desktops and vintage stereos.
Great video!, I literally uploaded a video putting together my first case last week (someone gave me the wooden frame section). Used the Frequency Central power which was my first attempt at soldering and it has been great so far!
Next time you build a box my man, use a square block of wood, or a T-square to check your center when you drill the pilot holes with a hand drill, it'll help a ton. Love the videos, keep it up.
Look MuM No ComPutEr Much LUV & thank you for the tip/link on the case power via Frequency Central had to order the Routemaster for our entry into the diy modular world.
Hey Sam! So I'm building my first case. 40 cm x 20 cm sides but only 80 cm wide, due to what wood I already had. Thinking about rail placement now. Can you say why you offset your rails so far back? Most other cases I've seen look to be flush or just very slight recessed. Is it so you can transport your cases with cables plugged in and not damage them? Thanks and keep up the amazing work!
I have a bench power supply(fairly cheap one from Amazon), I’m wondering if it works in the same way. I’ve had several failed attempts at making the ms-20 filter and the 1v/octave cem3340 oscillator, after troubleshooting, I’m beginning to suspect the bench power supply I’m using is the culprit. It has a +, - and ground so I assumed it would be fine but after poking my cem3340 oscillator I noticed that when set to 12v, the positive was putting out 3.8v and the negative was -8v. The power supply works fine on projects that don’t use bipolar power.
I have a question about the whole +/-12V DC. So, I came across and article that had shown that use of dual 12vAC/DC adapters wired together creating a +12V/GND/-12V and is the method I decided to go with because of the simplicity of it. Now my main question is...what in the heck gets connected to the -12V? lol The modules I have right now are basic 555, Hex, and Phase locked loops which can be powered by either 5V/GND or +12V/GND. What part of any of diy modules will be using the -12V? I've already blown six 555 chips with experimenting (wasn't the smartest thing but fun fire works in my studio!) lol Answers are greatly appreciated :) thanks
So can you do a little more about the power supply? This is the most informative video I've seen so far and all your videos are inspiring stuff but it sounds like, when I see +12 and -12 volts, maybe you can use an old desktop PC PSU. God knows I have a ton of those around. BUT what is the pinout like? etc. GREAT WORK! keep on preaching!
Pin out? Anything asling as the wires are wired up right. If you want to use the same connectors as in the vid search up eurorack power connector pinout
5 років тому+2
Quick question: why choosing 8 pins for the modules and bus board, when you've only got +12, GND, -12 (and the optional +5V) wouldn't it be easier to use 4 pins? ^^
-12v. Ground. Ground. Ground. +12v. Pitch. Gate. +5v. 3 ground lanes to minimise the chance of the +12/-12 coming into direct contact, and the magic smoke that ensues if they do. +5v is typically used to power a microcontroller, so you do need voltage regulators in digital modules. The other 2 lanes are simply for module communication. These are rarely used, and rarely used for their intended purpose. EG malekko use them to sync their sequencer modules, whereas tiptop use them as a mix bus for their drum modules. It's just the eurorack standard (which is actually 16pin not 8, I'm assuming the reason he's using 8 here is just for cost cutting reasons, or just what was at hand). Most eurorack modules use a 16pin to 10pin cable, and simply ignore the +5v and comm rails. It's a common standard, and so it's cheaper and easier to just use what already exists.
Hey Sam, did you take inspiration from Keith Emerson's Moog Modular setup for your stage shows? Your "Cosmo" synth has got an impressive presence onstage! Love it!!
The cases seem quite wide. I can see the benefit of the front space from the batons to leave cables plugged in, but was thinking of making a picture frame type wall mounting to hold my Kosmo's. Is the recommended width just for stacking the cases or are there cooling or other considerations that I haven't thought of? Cheers.
Man, will be cool if you'll be explaining oscillator circuits in details! I know some things but this is basically in the range of just one type of oscillator: saw core Jupiter8 design (made in AdamskiA videos). Very good oscillator (in terms of cheapness) but highly depends on DC stability.
I have a problem with my power supply. If I measure from -12 to +12 I get 48V and from -12 to GND I get 26V. At the start I have 12V but from the first diodes on it is 40V and also at the big capacitors. Can you maybe help me? :D
where can you buy large pieces of stripboard like the one sam has in this video? or is it just a bunch of smaller pieces connected to eachother? hope you read this i am very curious to know. and thanks in advance if you do!
@@freshescargot2470 I've never found long pieces like Sam has. Wish I knew where to get ones like that. I just ordered some of the longest ones I could find available on ebay in the U.S. I use 2.58" solder in screw terminals to connect power to the strip boards. Good luck with your DIY!
Sam, take bashed bits of broken electronics and strip them for parts to make your first modules: old stereos, old mixers, etc. Stuff that is junk and just being sold for parts/scrap... parts that most anyone can find in the rubbish bin. I like the idea of showing people that there IS a way to build your own stuff on a minimal budget.
I scavenge old electronics for parts and alot of the stuff inside is reusable! the biggest trouble with this idea is finding some kind of transconductance device. the CA3080 or even updated LM1700 are not going to be in regular gear that can be salvaged. These are unfortunately essential for stable oscillators/filters. however, some sound system equalizers have discrete transistor pairs which would likely be closely matched, which you could use for log conversion, etc. FETs are also not as common in consumer electronics, or logic chips... I definitely filled my parts bin with stereo innards and was making shitty noises before I bought actual parts but way worth it to just buy the parts IMO.
Pretty sure if you ask Frequency Central, they'll sell you an assembled FC Power - they sell assembled and unassembled versions of their modules, so I would assume they'd be happy to do the same for the power supply! But probably with additional cost? Just make sure to specify that you want assembled clearly because it looks like they usually just sell the PCBs. "Generally these PCBs are DIY only, but I am prepared to build them should you wish, please enquire." www.frequencycentral.co.uk/?page_id=1758
Could someone pls help me? I’m considering making a 5U MU style modular synth but I can’t find any info on making a power supply and such for such a synth. Can someone please provide some information regarding this issue?
indeed. but in essence the 2 rows are just joined together in eurorack. so just imagine the two lines as connected together. if you look at eurorack pcb's youll see the 2 lines are just connected together
LOOK MUM NO COMPUTER do you know any DIY power supplies that can handle up to 1.5A? I didn't find any on Google, maybe you know some good DIY websites?
The voltage rating on a capacitor lets you know the max amount of voltage a cap will take before it goes pop. Since these caps are being used for mains rectification I would stick with whatever is recommended to avoid any unwanted fireworks :)
Hey, Big thanks for your Videos! Did help a lot for starting to build stuff:) but i need to ask: where did you get that handle for your case? cant find it anywhere!
“ A NOTE”A quick note I possibly didn’t make clear! The power jack isn’t 240 volts! That would be crazy. It’s wired to a 12v ac wall wart. There’s a link in the description to it!

Depth: 1/3 of a foot
Height: 3/8 of an arm holding a budweiser

At least the interior size is 31" x 16" x 8"

good bit of advise there i completely forgot to mention!
A rectified 12VDC supply line does not matter in terms of phase. No synthesizers I know of are powered directly with AC, they all use DC
I have never made any attempt to have my power supplies in phase? It's all DC after the power supply so Matt Gaines is right!

I was hoping for a series like this. Thinking of diving into the analogue synth DIY pool, but have only basic knowledge of electronics. Cheers!
Hard out cool Sam... I always wonder how you get the time to make music design electronic at same time aswell as produce UA-cam videos...
You know what I was looking on your site for info on your kosmo case, and then this video comes out! Awesome :D
I'm going to have to plug the smoke alarms back in. ATX standards look like they might be more complicated to track than I remember but I really want to reuse and recycle.

This is awesome; definitely want more DIY modular!
Thank you very much for this video (series). I already had plans on building a synth and now I can benefit from your great experience.
08:46 doesn't wood mildly conduct electricity? Is there no risk of shorting here?
It shouldn't be a problem for a 12V circuit
Pretty excited about this new series ! :D
Super excited for this series! Exactly what I was looking for (:
You're a mad man and I'm absolutely fascinated
In the word's of a nother well known youtuber , ace!
oh dude I can't wait for this series
Can you make a tutorial on installing a eurorack rack in your center console?
Hey Sam, did you take inspiration from Keith Emerson's Moog Modular setup for your stage shows? Your "Cosmo" synth has got an impressive presence onstage! Love it!!

What's the advantage of buying a pcb over building the power supply on stripboard?
In your professional opinion how much play does the ply provide per player?
I have a problem with my power supply. If I measure from -12 to +12 I get 48V and from -12 to GND I get 26V. At the start I have 12V but from the first diodes on it is 40V and also at the big capacitors. Can you maybe help me? :D
love this! i’m planning to do a much smaller version soon and might just use that frequency central supply pcb
Like the strip board power distribution. I do that too!
where can you buy large pieces of stripboard like the one sam has in this video? or is it just a bunch of smaller pieces connected to eachother? hope you read this i am very curious to know. and thanks in advance if you do!
@@freshescargot2470 I've never found long pieces like Sam has. Wish I knew where to get ones like that. I just ordered some of the longest ones I could find available on ebay in the U.S. I use 2.58" solder in screw terminals to connect power to the strip boards. Good luck with your DIY!
Where can I buy strip board long enough for the pin outs ?what lengths are available ? Seems you can only buy small pieces
Sam, take bashed bits of broken electronics and strip them for parts to make your first modules: old stereos, old mixers, etc. Stuff that is junk and just being sold for parts/scrap... parts that most anyone can find in the rubbish bin. I like the idea of showing people that there IS a way to build your own stuff on a minimal budget.
I scavenge old electronics for parts and alot of the stuff inside is reusable! the biggest trouble with this idea is finding some kind of transconductance device. the CA3080 or even updated LM1700 are not going to be in regular gear that can be salvaged. These are unfortunately essential for stable oscillators/filters. however, some sound system equalizers have discrete transistor pairs which would likely be closely matched, which you could use for log conversion, etc. FETs are also not as common in consumer electronics, or logic chips... I definitely filled my parts bin with stereo innards and was making shitty noises before I bought actual parts but way worth it to just buy the parts IMO.
Woodworking protip, put a base coat of red on the wood, then black, and when it wears it's gonna look fantastic when the red starts peaking through.
What’s a good preassembled power supply and such that I could buy for a case like this? What are all the electrical components required?
Pretty sure if you ask Frequency Central, they'll sell you an assembled FC Power - they sell assembled and unassembled versions of their modules, so I would assume they'd be happy to do the same for the power supply! But probably with additional cost? Just make sure to specify that you want assembled clearly because it looks like they usually just sell the PCBs. "Generally these PCBs are DIY only, but I am prepared to build them should you wish, please enquire." www.frequencycentral.co.uk/?page_id=1758
Could someone pls help me? I’m considering making a 5U MU style modular synth but I can’t find any info on making a power supply and such for such a synth. Can someone please provide some information regarding this issue?
nice... been waiting for that 💪
Can anyone clarify how you wire two in power PCBs in parralel. Do I simply wire them both to the same power input. ? Tia
You put parallel from the power grid? has current enough for all right?
I cant figure out after hours how you built the extra sockets on strip board, like how did you connect it to the power supply and so?
Like what cable do you use to connect?
Hi Sam! It seems that 8pin connector differ from the eurorack one. Eurorack connector has two lines of 8 pin each..
indeed. but in essence the 2 rows are just joined together in eurorack. so just imagine the two lines as connected together. if you look at eurorack pcb's youll see the 2 lines are just connected together
@@LOOKMUMNOCOMPUTER ok, so if I put an eurorack in your one line connector, or if I put a kosmo into a two lines one it works anyway?
This a strike with a sharp blade against the conglomerates.
🚴♀️ keep it up
4 years ago everything was ‘AWESOME’ these days everything is ‘DOPE’. Anyway LMNC I think your videos are MARV.
LOOK MUM NO COMPUTER do you know any DIY power supplies that can handle up to 1.5A?
I didn't find any on Google, maybe you know some good DIY websites?
Where did you get those long PCBs for the power bar?
Still can't find them
Well there goes all my money on electronic components...hyped for the new series
Awesome! Looking forward for modular DIY series. Would like to get into modular world on a budget :D
What are those things you use as heatsinks on the powersupply?
This is the big brother i wanted as a kid
Is this power supply safe to used if assembled by an amateur with just a soldering iron
So awesome! So stoked!
Hi, great vid! I'm interested if I can use 0.1 uF 50v capacitors instead of 0.1 uF 100v ? thanks!
The voltage rating on a capacitor lets you know the max amount of voltage a cap will take before it goes pop. Since these caps are being used for mains rectification I would stick with whatever is recommended to avoid any unwanted fireworks :)
I love how he has an SH-101 casually buried under a pile of old Casios XD
Hey, Big thanks for your Videos! Did help a lot for starting to build stuff:) but i need to ask: where did you get that handle for your case? cant find it anywhere!
O cara tem um caixão no estúdio 😂😂😂😂😂😂😂😂 ótima oportunidade de fazer um Synth pra o Halloween !!
Do you ever break something by just touching it ?
Btw great vidéo. Thanks.
This is awesome, I can't wait to build one for myself!
Love your vids, mate!❤
Will you be making lids to protect your modules during transit?
