Make your own 10x10 LED Matrix

[@a.gromov3889]

The more I watch you videos the more I understand how it's important to have a proper tools to create such beautiful things

[@JasperJanssen]

(As a lazy man, I'd really want to make these in a grid size that is exactly matched to the spacing of the led strip. Holy reduction in soldering, batman!)

[@nosafetyswitch9378]

Very easy, just buy the stripe with the fewer LEDs/metre and thats it.

[@theshinyobject2438]

why not just use pre-wired led strings

[@Buzz-Tea]

I had the same thought 30 LEDs/m would probably work fine with just some solderings between different strips

[@shiftyjesusfish]

Ya wow, I have no idea why he did so much extra work. Low density (addressable) led strip then cover with a grid like he did....same result

[@guspaz]

Idea: if the acrylic was raised slightly away from the underlying grid, allowing a little bit of light to escape through, the light bleed could mask the dark spots caused where the grid is touching the acrylic. The distance between the grid and the acrylic could be adjusted so that a balance is found where the light bleeds enough to cover the gap between "pixels", but not so much that it bleeds significantly into the next pixel over.

[@BowersElectronics]

for the acrylic glass I usually just go through ally ways in my neighborhood until I find a flat screen TV. Plenty of useful parts, and a pretty big sheet of acrylic.

Wow, that is beautiful. I did a small solder job tonight after not soldering for the best part of 20 years and I think I did well. Wouldn't it be beautiful if there was 100 of these, all on one wall in a house! Imagine that in a games room, or a room with a nice stereo.. Or better still, under the floor with a clear Perspex floor omg that would be amazing. So it's settled. When I'm super rich, I'm having LED matrix floors. Sweet project man, very very cool.

[@TheHomerepo]

Hey Scott! Me and my brother got a Raspberry pi 3 and made your matrix board, we did however make it a 10x20 grid and programmed it so we played tetris. Pretty cool huh? The most tedious process was the hole drilling by far. The wiring got to the point of just being a routine and we took turns making it. It was totaly worth it and we really like your projects. Good luck with future plans

[@HypherNet]

If you use 30 LED/m LED strip, you can just drill holes in the backing material for the LEDs to show through and use strip for each row, only requiring soldering for the row connections. In your case, this would reduce the number of solder joints by a factor of 20.

[@geekdomsgrandma3740]

reading the comments makes me feel really stupid

[@lightguy250]

If you want to get technical, you could buy a small pixel controller (from a website like Holidaycoro) and use it to control this matrix over DMX. Basically so you can control it in real time and integrate it with other panels.

[@MitsuZer0G]

3:33 my inner perfectionist is happy 😍

[@MethodicalMaker]

Hey, you should take that up to the next level. a cool electrical project should get a cool outer look as well. saw off anything sticking out, wood filler the holes. sand it nice and smooth then glue down some nice veneer and stain it, or prime and paint it!

[@ElProfeGarcia]

good explanation, thank you, Saludos amigo.

[@sacul19700]

i currently make because of your video a led matrix with 24x12 :) will look awesome i hope, got the leds today but already drilled 1800 holes :D

[@tartletboy]

Hey GreatScott! Your previous led matrix bar inspired me to make a similar project that will look very similar to this when its finished! Keep up the amazing work cuz you do some great projects for electronics beginners (such as myself)!

[@madhatter2k]

I'm working on a similar project at the moment using nodemcu, allowing you to switch between patterns by curling a URL. This looks great and has inspired me more!

[@AmusementLabs]

Good job, but what about the programming side? Didn't you mention something at the beginning about showing us how easy it is to use? If not, what did you use to program the light patterns featured in this video?

[@Kori-ko]

I think it's the same software used in his video of a large scale one

[@jamesfromit]

FastLED. I think he shows how to use it in the large scale LED matrix video..

[@ThatGuy-nv2wo]

He used the arduino IDE(whatever it's called) with a library for the LEDs. There is a download on instructables.

[@beeldbuijs1003]

Tips: 1) Carve the acrylic (and similar plastic) plate with a sharp knife instead of drawing / sawing it. Then simply break it over the edge of the table. Easy, precise and fast. 2) Use white (or even mirroring, like aluminium (foil)) inserts / maze walls instead of black. Black absorbs light.

[@MrWilliam932]

haha, I made one of these out of wood and RGB LED strips for my High School Final Project it was 13x13 leds and a LOT more big and heavy. Nice video man btw

[@Kori-ko]

I was making a desk using frosted glass and a matrix like this underneath, using wood as the dividing material and I ran into that weight issue, too.

[@GoodOlKuro]

sounds cool. did you finish it?

[@Kori-ko]

I finished the structural portion and dividers of the top and wiring up the LED matrix, but I moved from Germany back to the US and still have the rest of the portion on hold while I get settled in. SMD LEDs were not the way to go and took way too long to wire up.

[@ramirocarranza8457]

It is so nice to see this kind of videos in milimeters!!!

[@killerdalek]

You'd have much brighter and vastly more diffuse "pixels" if you'd used white separators.

[@movingheadmau8128]

killerdalek i was wondering about the same thing but do you really think it makes that much of difference?

[@TimoBirnschein]

This is actually pretty cool! You should get one of those cheap 40 watts 400$ laser cutters. I got one a couple of month ago and it cuts 6mm MDF and Acrylic and stuff with a very good ventilation and a custom air support that you need to add yourself.

[@dennisplayinglacrosse]

I love how you took time to install each individual LED, but wouldn't it be easier if you kept the rows of 10 LEDs (instead of cutting single ones) and wired each row to the next one?

[@dennisplayinglacrosse]

Or does that make the LEDs look too tightly spaced?

[@WilcovanBeijnum]

Exactly what I was thinking...

[@Tom5TomEntertainment]

My thinking was that he might not be able to control them individually if they were attached together still.

[@DocM221]

THey're all connected the same in the row as they are in the matrix. He showed that when he did the test to control the spool of LEDs. ;

[@tartletboy]

The spacing would have been a nightmare to deal with but the setup would have been easier. he wanted a specific grid size so he made it work with a little effort.

[@SuperRalle123]

How is it controlling 100 leds with so many colors, on just one single data pin?

[@xubor007]

Asynchronous Serial Data

[@SuperRalle123]

xubor But there doesn't appear to be any for of microcontroller to read the Serial Data and convert it?

[@xubor007]

0:18, why would you "read" Serial Data? That makes no sense at all.

[@didaloca]

+Rasmus Tollund There is chip inside the LED itself. Lookup WS2812.

[@SuperRalle123]

Daniel Astbury Ah okay, thanks a lot!

[@chrisliddiard725]

@1:22 interesting to see the ground from the external power supply shared with the ground on the Uno to provide the data pin from the Arduino with a common reference ground. I thought this would be more involved, eg MOSFETs to relay the data pin, but if this works then it gets over the hurdle of finding 43w+ to drive those LEDs.

[@shaytaylor8860]

This is my favorite video/project you've done. I'll definitely be making one of these in the future. Great Job :)

[@TheViewFromUpHere]

Nice project. I would use 10 strips of 10 LED's to reduce the wiring by 1/10 and base the spacing on the LED center to centre spacing on the strip.

[@TheKill3rexe]

long story short :D ... After a quick test i can say that the connection of up to 65 LEDs is no big problem. But you have to take care of how bright you want them to be and which color!!

[@ThatGuy-nv2wo]

You can do any amount of LEDs(well not really, but a lot) it's the power supply that needs to be beefier the more LEDs you have, not the arduino which is just data.

[@mazegamer5698]

LucasMoviesmaker yes

[@BrazilianGaucho]

I don't think you can use an Arduino Uno for that many LEDs. You'd have to get a higher Arduino model.

[@mic159]

I would suggest using the ws2811 string type LEDs instead, that way you dont have to do so much snipping and soldering! Just drill the 8 or 12mm holes in the backing wood and slot the LEDs through.

[@allurared9029]

Also, why slice them up? couldn't you achieve the same result by cutting 10 strips with 10 on them and connecting the strips data in to the next strips data out? ( And power of course)

[@ciarfah]

claydioactive it'd be harder to isolate the LEDs into 'pixels' that way

[@grendelum]

That's what I was wondering as I watched this... using strips is a *LOT* easier. The only drawback to using strips is the LED per meter density is what sets the size of your 'pixels' as the spacing is preset... still, saves a *ton* of time and it really isn't hard to figure out... this seemed way overly complicated.

[@anahitamahmoodi1836]

wouldn't it still get the pixel effect with strips if he just separated them using that foam matrix? seems like it could to me

Too much work for most people I think with so many cuts and solders, but the end result is very appealing indeed. I would totally fill this thing with with lots of cool gaming retro pixel-art. I think it would be a fantastic product idea. If you could manufacture this thinner (and you undoubtedly could) and add a small bit of memory to make it programmable / wifi connected with an app it could act nice diffused normal lighting when you wanted and then switch to fancy mood-lighting according to timed program or instructions from app. Then just add support for multiple panels to work cooperatively and it would sell like hotcakes I think :)
