Interactive LED Wall - Arduino Code Explained
compared to hub75 RGB LEDs Panel is this cheaper?
These are about 1/4 the price of hub 75 panels and a hub 75 driver is also really expensive
hey i tried to compile fastled_test and it gave me this error Fastled_h directory of file is missing
Make sure you go to library manager and install the FastLED library before compiling
Please make it easy for anyone without coding😢😢❤❤❤❤😊😊😊🎉🎉
😢😢😢 when are you launching this
Next week! Be on the lookout 👀
@@TheTechRandom Keep up the great work, can you investigate USB videowall software called monitors anywhere. Secondly, in Africa it's hard to order PCBs like in USA , can u consider a simplified DIY video with not many things and no PCB , like indians do so that anyone anywhere can put this together. Led lights are there and led drivers but PCBs not common this side
Any relation to Peter Parker?
Did you not have to tie a common ground because you used a single power supply ?
Each panel has its own power supply so they are not physically connected in any way. There is no need for common ground because the data is transmitted wirelessly.
great job Sir 👍 I inspired to build also like this but I'm planning to use 60 leds per meter to compress the spacing of each leds. Is there a big difference on the performance between esp32 and esp8266? I'm going to build 108x42 per panel equivalent dimension of 108 x 168 total of 18,144 pixels. any suggestions and tips to make this successful plan and proposal of mine? 😍
ESP32 has a 240 mhz processor so it can process the pixel data much faster. I’d recommend using four of those as the receivers instead and the code should still work. You will probably have a low frame rate with all of that pixel data so you may want to switch from a wireless to a wired design. I have a video coming in the next week or so with my new high density LED matrix design so you may want to check that out!
@@TheTechRandom I prefer hopefully wireless design so that no more wires to be connected between each panels and to my laptop 😅 I changed my plan from 60 pixels x 108 pixels I plan to make it 108 pixels x 168 pixels. 108 pixels by 42 pixels per panel total of 18,144 pixels. 60 per meter ws2812b is it possible to build without any conflict on configuration and data transmission with a total of 18,144 pixels? 😅
@michaeldeloso9042 It should still work but you’ll need to use a few tricks if you’re hoping to get 20 fps. With 18,144 pixels at 16 bits per pixel, you’ll need around 6 Mbps of throughput. Unfortunately the current version of LMCSHD can only go up to 2 Mbps at best. You can probably pre-compile a gif as a pixel array and get a high enough frame rate but it will take a bit more work upfront. I’m working on a change that will let you run several USB devices at once from a single LMCSHD window and will allow much higher resolution walls without sacrificing color accuracy.
@@TheTechRandom thank you for your time replying on me Sir. by the way I suggest taking a look at jinx software that is also used by others to drive and control the led matrix. on my searching on this kind of project, I see a lot of jinx software appear when I try to look for a diy led wall.
Cool! I've got a small matrix (2x2 of the same panels) running with wLED, but I really like this, especially the video capture. Might be worth playing with. Go Beavs!
P1.5 setup pls for begineer
Hey man, im currently working on a LED tube light project. My Idea is to be able to create a bunch of LED tubes that can work individually, or connect together and work as a group of tubes. This could be very cool if you can link them to softwares such as RESOLUME to help enhance stage FX for shows. Im a DJ so this is something that will be very nice to figure out. Please let me know if I can chat to you about my project. Love your videos.
Sounds like a great project! I get a lot of people asking if I can help but I don’t have enough time to get to everyone so I’m thinking about starting a discord server where people can share projects and get help from me and the community. If you’re interested in that I’ll be launching it when I post my new video soon!
common mate you know who Builds the Best LED Walls on the Internet good Video cheers
My E5 wobbles, got a 40kg 200cm table top on it.
I have no wobble but I am on a carpet so that probably helps with sturdiness considerably
Also the feet are adjustable so you may have one slightly lower than the rest.
Badass.. Rock On
Wow, what a journey. You never know how brutally technical these things get until you're midway into the project!
Ever heard of tvs?
xlights and everyone else has the same issue.
My current project, which uses an ESP32, is a Domestic Hot Water Controller. It has temperature sensors which monitor the water in a hot water cylinder that has a heat exchange coil, and the temperature of a solar array. It then controls a circulation pump to transfer the heat from the solar array to the hot water cylinder. It also controls an electric immersion heater as a backup when there is insufficient sunshine. I used an ESP32 so that I could send temperature readings to a web page enabling me to monitor the system on my phone. It also has a "holiday mode" which prevents it using the electric heater whenever I'm away on vacation. The ESP23 connects to a time server so that it knows the date/time and switches back to normal mode the day I come back.
Try streaming the data with ESP-now.
I would so make a mini rambley. XD\
Seriously, no nyan cat at all in the video?
Just for you here’s a clip of it playing Nyan Cat off the SD card: drive.google.com/file/d/1TZDZ8KsBOZ9oU1r5EdzvgCFYohlSmyCI/view?usp=drivesdk
@@TheTechRandom thanks! You've turned my disappointment around 😁
with rainbows in it ??? Most likely it'll make my projects gay..........
Good thing it’s June 🏳️🌈
Project. I'm building a weather station. 2 units. One sits outside. With a few sensors. The other inside. The two connect via ESP Now. That dev board would make an ideal home base station to display the relevant information.
Stupid idea. Retro PC! At 240Mhz. That is Pentium 1 speed. Agon Light uses an ESP32 as a video card. So I wonder if an S3 could run as a 200Mhz Pentium ( window 98? ). Core 2 as the video driver.. Or. Just a second ESP32! Usb 1.1 is plenty fast enough for a USB keyboard and mouse. Large SD card as a hard drive. Just needs a sound card ( another esp32? ) and you have the hardware needed for a retro PC. Anyone fancy coding a Bios and firmware? Lol
You can't directly compare clock speeds between a x86 and an ARM processor. An x86 processor can do much more in a single clock than the ARM processor can, because it has a much more elaborate instruction set. And if you want to build a PC compatible out of it, it will be even slower, because it has to emulate those instructions. Next to that: the ESP32 has so little memory, I doubt anyone would be able to built a fully compatible x86 emulator out of it.
At some point it makes more sense to just buy a Big TV instead of an LED Wall😅
You didin't get the point of the video
Always love to see a new Tech Random video! Most underrated channel on UA-cam!
What is the resolution of the each frame that is being sent to the esp maybe you can do some form of compression or reduce the resolution before sending it if you haven't tried that already
The new wall is 182 x 128 at 16 bits per pixel with no compression. It could be a fun video to demonstrate the pros and cons of different compression algorithms
This would be awesome for my stationary bike monitoring system I wanted a data collecting device to run train an ML model on cloud now I can use this to make that as well make a little fun game maybe on the screen to make cycling a bit more fun xD
Your intro music is too loud and drowning you out. Need to tone it down so we can hear you...
will be fixed next video
@@kritik_edits And try putting the mic a bit closer to your mouth, it'll help the sound sound less tinny
@@PureGlide Just troll chris he will definitely 😆
Yes
Like seeing the extra "functionality" on the 3d printer. basic and works. general question on processros and such, have you considered to use older cellphones and repurpose them for the computing power for projects? Have a few and not sure who to use them (and seeing how poerful they are with all the functionality (wifi/usb/etc compute and integrated power. any pointers would be appricated.
So far I’ve only ever used old phones for app development but I’m sure there are some clever uses out there. Smart home control panels are the first thing that comes to mind
Can i Power my esp32 With 5v 30a?
If it’s a dev kit then yes. If you’re making your own board you’ll need to step the 5V down to 3.3V with a linear regulator. The 30 amps is the maximum rated current for your supply and not the amount of current that the board will actually receive.
I have 4 8x32 matix panels and they are wifi and also on my PC I have Signal RGB which sees them and all my lights in and out of the PC run in sync...can also mirror PC screen
Could you get signal to recognise them as an array of leds?. For mine i had to define every individual row as it's own custom strip
In order to make the gaps disappear between the tiles: Make the outer grid walls only 45 % of the inner ones (maybe even 40 %) so the edges move closer together. (Maybe you need to sand off a bit of the panels too) Instinctively, you might choose 50 %, but given, than no clipping together will make the effect disappear completely, you might need to experiment a bit with the amount.
What about window screen / shade cloth?
I know the sponsor was JLC PCB, but ive used them a few times before and they really are the bees knees. I really want to make my own led wall now though lol
I’ve gotten sponsor requests from other PCB manufacturers and they’ve even offered more money, but JLC is genuinely my favorite. They make complex hardware seem so simple
"led video wall" is the same thing but way more dense leds...🤔
7:12 u should have made the walls between the tiles half the thickness
the ali express site is not available ....would it work with WLED?
Turn a room in your house into a Volume!
You look like Jimmy's lil brother.
For $500 you could just buy a cheap led tv...
See my last video haha
@@TheTechRandom 🤔🤔🤔 Nah
Hey, I've been designing PCBs for 30 yrs and there's always some screw up. Don't sweat it. Fortunately, PCB production cost has dropped to near zero and companies like JLC make it so easy. I also don't mind you using the auto router for circuits at your designs' speeds. Keep up the great work on this awesome project. The stuff you're learning here, and showing us, will help with all your future projects. Thanks for the video.
Oh well played, well played! ARE YOU KIDDING ME RIGHT NOW??? Step 1: Produce a wickedly good and informative video; Step 2: LEAVE US HANGING!; 😂 Seriously though, I really appreciate the incredible effort put into making this video and the project itself. You and a very small number of other YT channels are REALLY making me excited for my kids’ futures. By that I mean, they have some amazing opportunities to learn anything and everything they could ever want to, and be inspired by experts from all around the world, unlike has ever been possible in human history. Keep up the great work 👍
One rule of thumb for video walls: the optimal viewing distance is roughly the millimeter LED spacing switched to meters. A 5mm pixel spacing is best viewed from 5 Meters or more. Super cheap Hub75 panel LED spacing as low as 1.87mm are available (for less than 1 cent an LED)
Looks fantastic! And I'd love to see some retro console emulation on it once completed (I was thinking GameBoy, but you could do others depending on the full resolution of the final wall).
16 times the Details
fahrenheit 451 parlor walls irl. Jokes aside this is awesome!
Cool project. I want to make one similar at some point. For the diffuser, get some clear acrylic or plexiglass and run an orbital sander with 480 or finer grid thru one of the surfaces.
I could hear it now, Todd Howard walks out on stage with you to reveal the new LED wall "16 TIMES THE DETAIL" and with the coding went. "It just works"
😂
Looks like ass..... Ping pong LED wall looks better
