Hi
Making this a seperate question.
Simply put… is this enough?
If not please please advise the correct supply needed …
Tried to figure it out but so many terms just fogged my understanding
Thanks guys
This may help
Hi tha ks for that i will have a look. However ive tried some calculators and left me numb… and more confused. Watts and amp… currant values all getting kentucky fried and poooof … brain melt…
But thanks will give this a look.
True before and after this moment lol…
Here we go…
Well…
After i rocking back and forth in a corner of a dark room… i screenshot the reselts…
Temperature? Well that changes by the day. English weather crap most of the time. Lol
Is this correct and exactly by link or product what power supply i should aquire… a definitive solution please.
Thanks you in advance …
One of these panels will draw 10 amps at full white, so 90 for 9 of them.
But that’s both a ludicrous amount of light that will blind whoever’s looking at it so if you want to make effects that are actually pleasant to watch you’ll only draw a fraction of that, and they won’t stand that for long without being actively cooled either, so you probably want to stay with that supply and make use of the limiter function, the “5V efficient (35mA)” selection is right on point for them.
Thanks.
The kinda reply i appreciate.
Thank you for the insight.
I plan to utilise each panel separately or layouts. Plus wouldnt xray the street that way lol
But would still like it bright.
Yes cooling did cross my mind. Thought i could get a slim 6" fan and attach to back of frame… and some “vents” down side of frame?
Or fan near top vents at bottom?
Would that suffice do you think?
Not only the Amps count, for stability is a fat and short wiring essential - and buffer caps in low ESR! PSU behind Panels in the middle. 2,5 mm² copperwire short as possible from PSU to each panel separate. And for each panel on panelside a 1000µF low ESR capacitor - gel is best!

Well… that escalated quickly! Lol…
Ermm… i dont know some of the terms you used.
Is there an idiot’s guide to what your explaing?
Also… at present it has microphone wired in.
So with 3 data outs for each row… can i still use a relay? As wish to cut power to the mesh.
I thought id show the state of play. Im no expert but hey im having a go ! Lol
I think its deep enough for that perfect glow
It has spacers i can play around with to tune distance
Plus may see if i can get anither back panel the same size. If the mesh is deep in the frame. Then i could mount a slim fan in the centre of the new panel and place and the back maybe? My need more holes on the mesh backing. Although there stuck now. Used some aliexpress Tony Stark double sided “tape”… sticky gum really… but its good.
Just have to find the right level of defusser.
Was looking at these trying to see if correct for this and not just plain white lights

I am going to want to use this… but cant find any data sheets or pinouts for it…
Not totally convinced on whats what.

Hi. Which one in particular should I use please…
Also…
A curious thing.
My aliexpress 5v 30a power supply. I multimeterd it and it showed 8-11v (with adjuster left and right.
Now in my mind shouldn’t it be 5v?
Wouldnall my 9 panels be enough load to drop that voltage?
Any help on this would be great…
RRD
If the supply measures 8-11 either it’s actually a 9V supply or you’re measuring wrong, but if it’s really 9 and you connect your leds to that they’ll all be killed instantly. It must be 5.
Hi
It would turn out it was my multimeter. Batteries low causing errors…
Buuuut.
Adjustments are nkw from 4 78 5.55 approx.
Problem is i dont think its enought.
Wled keeps crashing … seizing up… then reboots or i have to do it…
Dont understand.
One feed friom Power supply… to panels… ither toi esp… had to increase adjustor to its max as esp32 would boot up. Have to set limiter to 3
2500 else it freezes . This shouldnt be happening surely…
5v 30a. Panelnare no way close to there potential brightness. Can see when some effect roll … more leds that light up the first ones dim.
Any clues? It was suggest that i use a 1000 t capacitor inline some place … is that any brand?
I want to do a good job on this but dont understand why this is happening
If you have doubts about power crashing your MCU, I’d definitely dedicate a 5V supply just for the ESP.
You can use a 5V 2A “wall wart” or a 2@ USB charger.
Make sure you include a separate ground line from the MCU to the panel, dedicated for data.
That will let you guarantee the crashes aren’t due to power issues.
An earlier photo shows long thin wires, doesn’t show what’s going to the PSU but for 30A you need seriously thick wires or they’ll drop a lot of voltage and get rather melty.
You raise an interesting point.
So… lol
If i feel heat in the wires then that would suggest too much current? And if i double up the wires to my “POWER” knot would that help.? I need to see what current its getting.
Dont laugh but this be my power wiring…
18 gauge
That barrel connector will melt with not much more than 3a and will for sure burn your house down with 30A.
18awg wire is also not rated for 30A
I would use 2x 12awg
Check the rating of that terminal block thing as well. I doubt that is rated for 30A.
Thanks for advice… I will do what you say… Will research shortly.
So my power distribution is ok? Wiring at least?
I have an old mains power cord… could I use that? Not sure what gauge that is but it’s used for 240v (UK)…
That terminal block usually used for 240v connections…
Im just a little disappointed with outcome so far.
