Do you need someone to clean your science-room?
Walter P 🤔You mean like me producing a mess all day long and finding it clean every next morning??? My oh my, sounds like a lucid dream! 😄
Please publish the circuit for the board
Is it possible to still buy these boards? Maybe the file?
so i will be starting here!!
Hey man I need a 10 by 10 ft screen...
why not making 100x100
it is cheaper to buy leds on large flexible sheets (not stripes) and just connect them
I was shooting for something dense! Thats all!
Everything I found on the market was sparser than that.. (14 leds inside 98 millimeters)
Cheers!
10k leds is way too much for an arduino to handle. Some 10 times too much.
Hello Zep! Great video!
Have a question about the resistors, I've seen many (if not all) of WS2812B being used with individual resistors in each led, you didn't used any resistors there right? Is there a kind of ws2812 that needs an other that dont? Or why is this? Because if I can use them without the resistors would be much easy to do a custom pcb like you did : )
artesalve Hey buddy! Thanks a lot. I don’t know something about resistors to be honest! I think it is suggested to use one per data line, just before your first pixel, and thats all!
Then there’s the capacitors...In theory you need one for each pixel. You can work without them, but it’s wise to use them! My first pcb was made with one capacitor for each Led (on the back side) but I never bothered soldering all those 😄 So eventually I modified the board to take just one capacitor ( 1 for 196 LEDs, can’t remember the exact value right now..) and it’s working like a charm! Think of it as something to stabilize the voltage, a ups maybe..You can use a big one, or you can use 196 tiny ones and run your computer in both cases! And it’s fairly easy to make one of those pcbs , yes!
Cheers
Great! Thank a lot for your explanation and motivation. Now having more courage to make my own pcb design with these neopixels. Appreciate your help!! ; )
No capacitors?
Kindly How this many LEDs are installed in modern 4k tv ?
Ελα ρε φιλε,χαρας την υπομονη σου,το αποτελεσμα παντως σε δικαιωνει πανηγηρικα!Μαστορας τελος.respect
Αργυρης Πανωριος Ευχαριστω φιλε! Ναι ειναι τα ατιμα τα λαμπακια.. Ωραια να τα βλεπεις!
Zep Labs ναι ναι ρε φιλε ειναι πολυ ωραια
Thanks...!!!!
Can I ask what temperature and air setting you were using for soldering the leds?
Nice work on the surface mount soldering, even with a stencil that takes some patience and a steady hand!
Güzel bir çalışma.
Love your Presentation /Instruction.
Hello I'm wondering where can i find this board at and the Stencil?
Diy in the Ghetto Hey buddy! I 'll be releasing them someplace in the near future I think, just have some testing and further development to do for now..Thanks!
Im interested too on were to find/purchase the solder plate (stencil) with the holes for the solder.
Let us know when a where to buy it.
Thank you!!!
Any chance you might have the PCB layout available? Gerber files even?
NuttCorp hey Nutt! These are what I' m partially make my living out of (or will be!) so I can't share the gerbers here! Hope you understand 🍺
Zep Labs I got yah. Makes sense. :)
Thanks! Interesting you get away without the little capacitor to each led. I always suspected you could, but the datasheets insist on it.
In my experience, you can do with just one at the beginning of the string. And probably a small resistor on the dataline just to be on the safe side.
Jose Baars The freaking persistence of them datasheets! I believe they are more forgiving than other LEDs (cause of the chipset "regulating" the voltage inside there) but they still could use that capacitor! Just skipped them for now...thanks Jose!
U r creative one mashallah
Thank you! Cheers!
hello would you consider sharing the PCB design ?
Yves BAZIN hey Yves! Sorry for the late reply.. I 'm afraid I can't share this one yet ( it' s part of what I make my living out of!) Hope you get it! 🍺
Zep Labs I totally get that !! ;) can we buy these somewhere then ?
Yves BAZIN Glad to hear! I hope sometime soon...I' m a bit in the testing and improvement process yet..I have to narrow the gaps where they meet just a tiiiny bit more..I 'll have that on video soon! 🍺
You can give the gerber files of the PCB Matrix Please!
Plz set the langage of the video to have automatic subtitles
I highly doubt they 'll catch my funny accent, but I ll give it a try next time!
Its cool to put it on gaming pc nice video bro
I am looking for those types of boards how do I get them? The place in town here is a rip off for a custom made pad
Order them abroad! They are very cheap nowadays!
you best get soldering because we're all coming to your place this summer for out door cinema :)
John Made it it's in john! You get the popcorn, I' ll have the beer 🍺
Great stuff Zep. Curious if you have you tried out the FastLED library for controlling pixels? www.FastLED.io
Marc Miller glad you like it Marc! The name rings some bells, cant tell for sure...but I'll surely dig into that..thanks!
why aren't capacitors used on the 5v line near the leds?
Cause you dont need them as badly as they let you think! And beacause this one wasnt finished yet!
Don't get me wrong, they sure have a purpose to serve, but you can run those thingys without any ( for guite some time actually) and be golden!
As you may see on other videos of this project, I ended up using a bigger cap for each one of those boards.
Cheers bud!
I like the custom PCB's. Another good build, placing all the pixels looks laborious!
Spikey DaPikey I 'm catching myself thinking of a custom pick n place machine! That laborious they are 😄 Thanks Spikey!
I checked the web site to buy some of your boards. Are you planning on making more?
Hey George! I have some of them available as a matter of fact. Sold 2 or 3 of those but after that they werent moving so much. So I never relisted them! I guess most people dont wanna solder the LEDs themselves ( personaly I quite enjoy that, but I can't blame them!)
So I have some thoughts on putting out some already assembled of them boards, but between a ton of different projects I cannot tell when this is gonna be!
If you still have some interest on the board , let me know and I 'll relist it!
Cheers
that's great is there a way to pm me or email me?
Sure. zeplabs@gmail.com
πολύ καλό το βίντεο. Αλλα καλό είναι άμα μπορείς να μας εξηγείς και στα Ελληνικά γιατί λόγο λίγων γνώσεων στα Αγγλικά σε χάνω . Συνέχισε έτσι .Ελλάδα από που είσαι?

The PCB boards are not available anymore :(.
New ones?
Sorry for that Avi! Will fix that soon!
Pcb board is not available
Thats cool, where did you learn all your skills, formal or day dreaming and having a go?
Burt Johnson Glad you like it Burt buddy! I do have an engineer's degree (mechanical) but it has always been the daydreaming for me 😄 And a technician father helps a lot!
where do you live my friend?
Walter P I live in Greece buddy!
I live in Italy , Milan but I'm always out for work. I like mediterraneam culture , we are the best from hystory to now but fucking politics and global power want to destroy us. But we don't release ;)
Walter P Freaking politics! Say that again man..keep it up and keep it true🍺
You have a dog? 😀 Nice display...
satyrek123 I wish! It's the neighbor's dog..still barking as we speak 😂 Thanks buddy
Can you explain the code for the text that you displayed at the end of the video?
Hey Danish! Sorry for the late reply..
The code from that comes from the Neomatrix library (link to that on description). It's the Matrixtest example modified to match my hardware and it's fairly simple!
Give it a try and let me know if you have any probs on that!
@@ZepLabs Thank you so much, really like the work you are doing- your fan from India.
Dont know where you get the patience Zeb.
Anthony ihavenoidea 😄 well I tried meditating...but it gets me asleep every single time! Try the blues buddy!
Straordinario come sempre Zep!!!
L' impermeabile Schiano contento che ti piaccia amico! Grazie
Hi, I've one silly questions. Did you use any capacitors in your board ?
I guess the 4x4 board you provided have capacitors in it but your board doesn't seem to have that.
Hey Hasan! Not silly at all my friend...
Actually you are right. According to the datasheet of those thingys you are supossed to use a 0.1 uF capacitor for each one of them. Which I always found a bit annoying!
In fact it is wise indeed to use a capacitor. On the larger display I made I used one for each board (196 LEDs) and I believe it was 25uF. But then again, it's not a necessity I guess. I have also made an RGB studio light using one of those boards(without a capacitor), which I have used for countless hours since, and is still working like a charm!
Cheers
@@ZepLabs Thank you so much. One last question, what could be the best solution to light up the 10x10 panel without using power supply ?
Iqramul Hasan that’s a tricky one!
Well they use power to light up, and you have to supply that... So at any case, if they are lit, you are using a power supply of some sort! 5V
If you don’t have one arround, you could use an old computer’s power supply. They also have a 5V line ( just check the amperage. We are looking at 3-5 Amps at full brightness white!)
You could also use whatever power supply you have on hand, and use a stepdown circuit (DC-DC converter) to get it down to 5V. An average laptop PS unit can do 2 Amps at around 20V . Should be more than enough when dropped down to 5! Just make sure your stepdown can put out 5 amps!
Actually what I mean is I don't want to use those dedicated 5V power supply or computer's power supply because that needs AC voltage. I want to make it portable. Like I want power that using any powerbank which charges our phones but not using those external power supply which you're talking.
Is it possible to powerup 10x10 board using powerbank ?
@@iqramulhasan1217 Yes, some libraries even support you setting a limit to their amp draw from the software side.
I recommend the FastLED Library for this.
If your library cant limit the max current, then calculate it yourself, and make your own limits to not go over your 2.4a (or w/e) rating of your powerbank :)
