Has Anyone Requested a POWER SUPPLY PCB?

Hey guys apologies if this has already been covered, I did the search function and all that, and didn’t see anything come up.

For all the money we all throw down on expensive multi-pedal power supplies, the circuits don’t SEEM that complex to me with a layman’s eye. I did a bunch of Googling for “DIY pedal power supply PCB” yadda-yadda and that rabbit hole led nowhere.

There is THIS…

fx power source - 8x 9v, 2x 12v and 2x 18v - full kit | Anasounds

With this FX Power Source kit, you can build a powerful power supply for a pedalboard with up to 8 pedals 9V, 2x 12V and 2x 18V!

…which LOOKS awesome, but despite their slick website I don’t think these guys are necessarily still afloat. I contacted them about their payment system being down and they said “try our alternate payment systems” but those were busted as well. I signed up for their newsletter so I could get their build docs (and perhaps schematic?) and the signup confirmation/link never arrived. And their cart says “backordered” in perpetuity. So, yeah: not sure they are viable.

And yes I realize the Anasounds one isn’t fully isolated but hey it’s sumthin’.

Perhaps this has not been tackled by the commercial PCB sites for fear of liability issues and dealing with high voltage? Otherwise this seems like an easy need to fill with a big potential market, myself included.

What gives am I missing something? Educate me!

I've built a power supply pretty similar to this one! It's not isolated, but has worked really well for my needs so far (only digital ics i ever use are pt2399, so can't vouch for how it would work with digital pedals)
 
Interesting, that PSU looks like something joyo is doing. When it comes down to it. The DIY community has looked into PSUs, and the consensus is, they are cheaper to buy than to but parts and build.

This one is actually super cheap to build. It's basically a combination of caps, diodes and regulators. It has served me well so far, but i'm certain it could give some kind of problem down the line depending on the combination of pedals and what not

If you're playing in bars every weekend, you run into some dodgy electrical outlet wiring. One time, we tripped a breaker that shut down the electricity to half the bar. Terrible gig, never went back.

A (not so much) fun fact: just last night i went to a concert and a power outage in the street (not the venue's fault, which is actually quite a nice venue) left half the place (and the stage) without electricity, so the wounds are still fresh regarding what you're talking about :LOL:

Oh wow, end of show, huh?

I suspect this is the case. Some locales may also require a license to build anything that works with mains voltage.

Then again, several sites sell DIY tube amp kits. Not sure how that would be different.
 
The MP1584EN is an adjustable DC to DC converter that operates in the megahertz switching frequency. As such it is totally silent. I'm using it for a battery powered DC supply for my 18650 pedal power. They are like a $1.50 on eBay and the size of a postage stamp. They will supply 1.8A continuous and will smoke at 3A.

I have several designs of this, most with more batteries, but this would supply 4 to 5ah depending on the type of 18650 battery used.

I found this as well after reading the power supply discussion.
I was able to sign-up for the newsletter and get the build docs. It does include the schematics and BOMs. I am happy to share that information and would love it if @PedalPCB could do a version of this.

Cool! I wonder why my signup failed!?! Thank you for sharing!
 
I’d be surprised to find anyone outside of the original Small Bear owner (Steve Daniels) and that ilk offering up anything. The power supply industry can run circles around anything we can build. And any of the dodgy outliers have likely died of natural causes at this point. Yes there’s still cheap shit out there but likely STILL better than we can do. Buyer beware of what you get for the price. It’s one of those things like trying to design your own op amp that the DIY camp will never catch up on. Now if it’s a real weird combo of voltages, that’s another thing…
 
I've been learning about PS's lately. Comparing commercially available ones. I have a Cioks DC7 and it's shocking to me how small it is, without a brick. Because Strymon (2 stage SMPS) and Voodoo x8 (hybrid SMSP) all have bricks. Makes me wonder how good the cioks is. Most of them have 2 stages, 110-230 stepped down to 24v, then down to whatever 9/12/18 volts you want.

I'd love to build one, just not sure where to start.
 
I've heard nothing but good about the Cioks. I use the standard 1-spot on my work bench and a Dunlop with the 18v brick on my live rig and it's never done me wrong. Pictures on the original AMZ diy power used to be from my build (not sure they are anymore) but it did me well for years. I ran into some overheating issues I think but no complaints.

you should head over to the troubleshooting forum then think about what that place will look like with builders messing with 120 VAC instead of 9 VDC
 
My CIOKS is solid & reliable for ... a decade or more now?

Originally, I'd have gone with the GIGRIG if my pockets were deeper, but now plan on getting more CIOKS.


There are some DIY avenues to making my own power-supply that I've found, but none that have the features, reliability and lack-of-killing-myself that a commercial supply such as CIOKS has.
