Making oddly satisfying LED magnet tiles

Led tiles are cool and those bulky addressable WS2812D LEDs have a nice retro touch. What started as a LED wall tile ended up as a magnet gadget in the end that likes to socialize with its friends.

Hi Bitluni, The link of the magnet connectors leads to the LEDs. Can you fix the link? Thx! Awsome work.

[@bitluni]

link fixed. thx for the hint

[@D1zZit]

@@bitluni can you also fix the github link for the project? Also broken

[@msmith2961]

Soldering the magnetic connectors was hilarious 😂😂

[@1kreature]

I did a similar project about 18 years ago and I implemented the water-ripple simulation. I think you should do that with the tiles! It would look fantastic when a ripple can propagate from a single "randomly excited pixel" on one of the tiles and spread as a water-ripple to the other tiles. The choice of reflection, inversion or something else at borders offer some fun variations as well.

[@JemEklery]

I can imagine some 2D platformer game on these, where you have to move LED segments to discover more world :D

[@dvohwinkel]

Project files giving a 404 error. REALLY cool project!

[@backgammonbacon]

Excellent work, 5 iterations is pretty good. You need a buddy to remind you to check if your pads are upside down/mirrored or not.

[@vonries]

I haven't worked with electronics in quite some time. It is nice to visit the old community and see things are going well. You always do such cool work. Keep it up and good luck to you.

[@UnexpectedMaker]

That's a wicked result - where can I order a lunch of them? :)

[@Maxjoker98]

Mmmhh... LEDs! It's lunch time! ;)

[@PrinceShehzad]

I don't think they are edible, but you can try a bunch of them.

[@LogicalDraws]

They BRIGHT up my day when i eat them! ​@@Maxjoker98

[@hannesknofel8408]

Having a programmable, extendable led-Display with that would be amazing! Please continue working on the code, this looks amazing :)

[@cristiturcanu7769]

Time to run Conway's game of life on these bad boys

[@nevyn]

Oh man these look fantastic. I would love to build some of these and hack together some nice patterns or something. Maybe angle the sides so one can make rings? Make a hexagon version?

[@Saleca]

Thus could be a really cool eletronic puzzle

[@0xDEAD_Inside]

This is really really good! I was looking for something similar and lo & behold, bitluni uploads magnetic version of it!

[@Fabian-_-]

Some more info on the blender modeling part would be cool, I recently tried to model something simple and struggled quite a bit using Blender. The other CAD programs sucked or didn't work well on Linux, so Blender was the best option, but all the boolean stuff wasn't as nice as I had hoped it to be. Wouldve been a lot easier if one could simply group objects together like in 2D in Figma for example

[@IndustrialJones]

For booleans you want to check face orientation (all facing out). The overlay drop down has an option for it. Just takes time but it gets easier. The default units to work in is meters but I use that as centimeters. 1 unit = 10 mm and export at 10x scale. I tried working in mm but the scale feels to small if that makes sense

[@MichelSatoer]

Free Fusion has a limit of 10 active "editable" projects. But you can have a many projects as you wish if you make the previous projects "Read-only". (See the sidebar with "My editable documents"). If you need to edit a read-only project, just make ik editable again. Just make sure you respect the max of 10 editable projects at the same time.

[@Ahadun]

thanks for da tip

[@sirseriously]

Also - you can usually pay about $10 to get added to a school/company license to get access to everything, if you know a guy...or have eBay.

[@martinslade6741]

​@sirseriously wait for real? I'm a hobbiest and I'd happy pay $20 a month but not $700+ a year!

[@makers_lab]

@@martinslade6741 which is why you use the free version, which is free for non commercial use and fully functional with no meaningful limitations for almost any type of non-commercial project. For commercial use, $700 a year isn't a big deal.

[@richards7909]

This style of LED imo makes it look even better :)

[@ZERR0R]

You can make a puzzle game, where different modules would light up different patterns on 4 sides, and you have to connect them in such a way that adjacent modules have the same pattern on the common side. The only thing is that they don't have built-in batteries, so disconnected modules won't light at all until you connect them and see that the pattern in not matching...

[@Jasmohan]

Pretty cool project

[@АлексейГорький-в8е]

You can use a heat gun with solder paste, to solder magnets. Another way around this problem is to close magnet field on one side with metal, this will significantly reduce the strength of the magnetic field on the other side

[@johnacsyen]

The magnetic connector link to AliExpress links to the rgb led

[@tonysfun]

Just like usual, you are very talented and even your video's are well done! Thank you for sharing your ideas and videos.

[@deathshaker0026]

Oh cool. I love the idea!!!

[@jammidj]

this is awesome. id buy ten asap

[@LukeHoersten]

Incredible project!

[@Ernzt8]

Great project!

[@sweeeenay]

These are really cool looking. Soldering that close to a magnet looked painful haha

[@lorenzorentniop717]

Nice! I like these

[@madwilliamflint]

That's some gorgeous work.

[@ergindemir7366]

Those cells consume up to 2A each, in your case it's unnecessarily dense. If you want to chain them properly you should go for the 12V version of the nenopixel.

[@guyh3403]

Wow. Just wow.

[@testman9541]

Those LED are great, I would love that there exist with an embed touch controler 🎉

[@HDefectus]

Got a 404 on the github link btw

[@lasarkolja9692]

I guess the repo is still private.

[@montazvideo]

I don't know if it's feasible or not, because of potential size problems, but these leds look like they might just slide in some 4pin sockets soldered to the board instead of soldering leds directly. (?) It might solve your replacement issue.

[@panconkisu]

THIS IS SO COOL!!

[@rondlh20]

Very cool, amazing!

[@3Dgifts]

Awesome project!

[@hulkgqnissanpatrol6121]

You're going to be one rich man soon! Fantastic job 👌 Simple game of Snake 🐍 maybe? That way you can challenge yourself to programming a simple Bluetooth joystick and 2 button's? 🤔

[@paulushdk]

Amazing as always 🎉

[@daemuth9614]

These look amazing! I'd love to build these. Would it be possible to request a tutorial? I can solder things just fine but the details with the programmer go above my head.

[@JanSt12]

Mega =D Als keyboardwarrior muss ich sagen, dass ein weiterer Pin bei den Magneten, für einen einfachen& schnellen wled Anschluss noch das I-Tüpfelchen gewesen wären :D Aber mega Projekt & Ergebnis

wake up! new bitluni video just dropped!

[@hannesknofel8408]

I would love to see you continue on the code for the latest led-project!

[@user-vw4cg8cy4f]

To reduce the amount of simple mistakes in the PCB design, just print it out 1:1 scale on a sheet of paper how it would look once its fabricated. I caught many mistakes this way which were not obvious when viewed through a monitor.

[@HiLight7777]

Really great video. I like 🤩

[@marcusm5127]

Very cool. Could you make a large one for displaying pictures? I love the idea of a diy art display with high brightness capabilities.

[@OscarSommerbo]

Magnet connector link ends up at the led page... And the github link is broken too.

[@qiou29]

Github project name has changed if I remove 6x6 from the repo name.

[@SirSpence99]

You have a messed up link for the magnet connectors, it goes to the leds instead.

[@diyhard666]

This is by far the most impressive led wall i saw. Did I understand it right, if you overrule it with the Arduino it can play videos?

[@domcxz8643]

This is crazy :)

[@Bubatu7]

that's awesome

[@skyslycer]

How did you code the tiling boarder thing, it looks like it's complicated logic. Really cool project!

[@shadman1911]

outstanding!

[@ms2649]

Would you happen to know the maximum current draw for those magnetic connectors? Depending on how large the panel will be it might get quite hot.... Especially since the contact point is well... A point Great video though 👍 EDIT: you should turn it into a tilable subscriber counter (as a practical example and then can say "like and subscribe to increase the tile count" 😁)

[@Adventures_EC]

if you don't bother add the resistors, they will not last long. THe main reason for the resistors is to limit the current and not allow the LED's to die

[@sirtra]

How big can it go? Theoretically up to 255 in any layout if im understanding correctly? 🤔 Looks amazing with just a handful but 255, that'd be... 😍

[@AmirASD]

AWESOME

[@leeashleyanthony]

Dupont connectors? Sorry, Pin Headers... But I'm not sure if the pitch of the LEDs would be thick enough.

[@jstro-hobbytech]

That's awesome. Who do aisler use as a shipper to north america? Dhl charge 17 dollars at the border for brokerage fees. They are the worst if you live in Canada. They are my favorite addressable led type. I have a ton of them.

[@MAYERMAKES]

A tutorial on the code would be cool. I can´t figure out in my head how the auto tiling works.

Maybe Onshape is a viable and free Fusion360 alternative for you

[@4kleidisc]

wow im super early! this is a great project

[@wchen2340]

Do you really run them full brightness on a daily basis? I find the brightness of my 300LEDs matrix way too much. I can barely use the lowest 3 or 4 bits in my colorspace otherwise its just agressivly bright. Im still torn if its worth to put another filter on top of the diffusion glas or if i should just leave it like that.

[@auxz2jz158]

That's cool where can I order about 300 of them

[@malimaru42]

this is so coooll yeaaa yippeee

[@leeashleyanthony]

Get PCBWay to assemble them, giving them a BOM

[@MrWeebable]

Is it possible to make a game out of this? You simulate a bouncy ball and you have to disconnect en reconnect tiles in front of the ball to keep it from going out of bounds.

[@gestaltlabart]

I made my stuff with blender too but Freecad is coming in strong nowerdays ...

[@jozefhercegml.6224]

what circuit board making programme is that? i use aegle but that one looks good too

[@peter.stimpel]

Love it, well done. But only 5 versions seems to be a bit too fast for my Luni taste ...

[@PUREBLOOD0001]

can you broadcast an encoded video thru the LEDs to a camera to receive the light input and decode it with arduino - visual light communications

[@v.k_]

Heyyyy, you put wrong link for the magnetic connetors
