As yes, you can do this at home, IF you know enough about electronics, 3D printing, coding, and have money burning a hole in your pocket.

i wonder if it would be possible to introduce some kind of delay per panel such that all of the panels update at the same time, just using some example out of my ass; assuming the panels have a uniform update time of 1 millisecond the first panel in the chain might have a delay of 16 milliseconds and the last in the 16 panel chain would have a 0 millisecond delay

Clicked this video cause the title says : " led wall for $5 per tile " .... Now I have to go to university again ...

I know this is old, but you should look into Chemcast Black LED Plastic Sheets . It is specifically designed to allow light through, but it's back and diffused

Well there's a project I gave up on. I was working on the pixel density by using individual LEDs. I love soldering, just not that much.

I am an embedded firmware engineer, If you would like to improve the framerate of this system I would be glad to help!

That's like 3rd video in a row that uses Vivaldi's Winter. Algo knows I love this tune...

Great looking project! Would it be possible to get the framerate faster than 12 fps? A video wall with 30fps would be fantastic!

If your TV is Android, sideload SmartTube, that will solve the issues you're having. I don't get any,. The author(s) also patch/fix issues pretty fast. I refuse to use the official app coz it was so terrible.

Bro, why didn't you just play from across the room? With all of the money you spent making that wall, I'm sure you could have bought a few extension cables for your keyboard and mouse.

Bro, why the hell are you soldering the wires to the surface of the through holes? Put the wire through the through hole and solder it in.

Now my question is: How much did it cost you in total?

I love seeing projects like this with unique code rather than wled. Wled is awesome but ideas like this are just creative and more fun. Like that was a game of chess you were playing on it at one point right?

What about the software? What are you running on those ESPs? How do you get a HDMI signal to them?

Thank you for such a great and informative video!

what song is the outro?

What would be the method to have this powered off of a DC power adapter or such, assuming there is on board memory

this comes with the metal brackets for the HDS?

You are a genius. Thank you so much for sharing the files :)

This one looks pretty bad tbh, you improved a lot on the newer version

Are you going to turn it into a bracelet or something? I know you mentioned that making an actual ring was difficult and expensive, but how can you wear this board? Seems like a bracelet or armband or similar would be the next logical step.

why not just by the led tiles and controllers?

Is there a way to make the spacebar longer so that it can replace fn key on bottom left

We really live in the future, to think you can just order whatever your brain farts out and it gets to you assembled is just amazing

Ur stability test test so awkward

If you make another iteration of this control board diode the positive off the power supply and the usb power together. One per incoming positive supply. The only diode that will gate will be the one with the highest voltage. They use this same setup in emergency switchgear all the generator batteries are dioded in as well as a station battery. Makes hot swapping power supplies possible.

Another day I am very glad that sponsorblock exists. 10 Minutes of sponsored segments on a 25min Video is absolutely insane lol

Basically 2 ads in a video, one 7 minutes and one 2,5 minutes.. I am sorry but this has to be one of the worst formats I've seen in a long time. The topic was interesting, although the ads made it unbearable.

i can barely listen to this video with how badly the mic audio is peaking.

7 mins of yapping about the sponsor, you talk a lot!

Pretty cool project. Matches the level of polish I leave them at. lol. Gotta love the arduino community makes development so much more enjoyable. My favorite project so far was a heat sensor for a portable AC unit. Was a lot more complicated to actually fully implement than anticipated, but I got there in the end. It measures how much heat the AC is rejecting. You can see that value slowly drop as the summer goes by and the fins get clogged as it was very dusty this summer then jump when you clean it. You can then calculate the COP which as advertised was just under 3 even 13 years later.

7 minute ad for a referral code, then gives up on actually making a ring after about 2 minutes. Lame.

Cool project! But unfortunately the title is very misleading. I clicked, wondering how "a normal person" could possibly create such a smart ring. I was a bit disappointed that you ended up building a "normal" PCB.

Great video! That ring's battery charging process sounds like garbage. Could be a fun video to "fix" that and go into BMS and lipo charging and such. Thanks!

What do you think about this new video format? I thought it would be cool to look at an existing product and give my perspective as a professional hardware designer. If you have any suggestions for future videos I would love to hear them!

I've been wanting to get into designing electronics for a little while. I really appreciate you going through the entire process. How is it that you go about searching for the different components like the sensors? Just checking what jlcpcb has against what you're looking to do? Any tips for getting chat gpt to spit out the code you want?

perfect engagement ring for you 😝

I know few people see your video, thank you for continuing I myself am interested in making video walls, I will be happy if you make them more and better And I also had a question, how can I become someone like you by reading and working, that is, professional electronic engineering?

awesome job!

whats the original rack?

This has given me a better understanding of our church sign out front & how to repair it. T_T

These guides are amazing <33 Thanks bro

Can you please provide the CPU temperature and percentage code yoyu used and how to connect the Crowpanel 4.3" display to the ZimaBlade? I have a Raspberry Pi WH if that is needed. Thanks in advance!

for the love of god, secure those hard drives so they're not sliding around and vibrating to death.

Why u didn't order regular matt effect acrylic sheet?

Uuuuuhhhhhh you SOB. Ive aquired about 100m of led strip since my first POS set from aliexoress. Didnt know led would require so much learning. 8 months later and probably a couple 1000 dollars in microcontrollers, soldering, 3d printer(havnt been successful and vety impatient, need to try again) and led strips. I can kay them out in the order i bought them and you can watch my learning by trial and error. Starts at ali strips with a whopping 18led/m and i diode thats maybe a 20/20 24v. Then the 12v 5050 90/m(im learning, but guess who hasnt figured out RGB and ARGB), then ws281x 90/m(figured out the difference hardway) . Then ws281x 144/m(found out about hot spots in diffuser) and finally COB 700somethi/m(i could probably griw weed if i turned everything ive aquired on at the same tjme). Now for my magnus opus that keeps getting bigger every new idea. Plus if i bought, damniy im using it. So any kjnd DIY i could come up with to use thr crap strips. A lot jar lights, lamps from poster tube and diffuser Sheets scavanged from lcd monitors, lamps out of Old mobos connected together like a cube, led light clocks made from old 3.5"HDDs with motor Removed and cheap led fan clock placed in the vacant hole, infinjty mirrors From cardboard boxes. Still have meters of those shits left. Thf good stuff Has gone to modding my 4 gaming builds and running from them to a panel wall i built from the tops of old office desks. Using diffuser channeks, diffuser tubes, and other components i snaked thd leds on the wall like it was tracings on a PCB. I synced all thr pcs running SignalRGB. Ive trued with wled to connect the dumb rgb. It involves MOSFETS with 1 diagram in the whole internet, got frustrated and quit(still learning circuits lol). Luckily my mobis have 12v headers, so i plug inti them and signal drives them. Oh yeah the LED cloud cieling. Of bunch of leds in random patterns covered by cotton stuffing. I converted anything i had argb i bought cut off controller and wled. NOW i have to build aa f"^#*ing jumbo tron. I blame you as well youtube . U should come with a warning for people with ADD. All seriousness awesome sauce man.6 months ago id have no idea what you were doing but i think i got it now. But now im forced to actuality learn my printer. It just takes so damn long😑

you could make something like a ribbon display which is like those displays you see at stadiums, very long and the graphics that get put on it is really cool as well!

I think the Display will be more easy and convenient to work on top!

I have a 6.25ft LCD display with a 4k resolution for under $500, does that count? It's called a TV.

For the acrylic, why not use larger sheets of like 120x240CM?
