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

See my last video haha

@@TheTechRandom 🤔🤔🤔 Nah

😂

I chose the ESP32-S3 specifically because it has dual cores so it can handle the amount of data it will need to process to achieve a decent frame rate but also its programmable through the Arduino IDE making it approachable for most hobbyists who may want to try a project like this on their own!

@@TheTechRandom first point is valid, as generating frames on the fly is way faster than, for example, reading data from SD card (it can take up to 5 ms for 4k points), but peak framerate is also limited by speed of LED data transfer - I believe that was the reason that some listings or darasheets state that maximum LEDs per line is 2 or 4k (though tere is no actual limit). but the Arduino IDE is still a method to program a controller so you still need to deal with coding at mid and low level and to interface different libraries with each other. It's no big deal if you're an engineer or at least coding hobbyist. But what I can see, a lot of hobbyists who specialise on practical skills like cosplay, crafting, making miniatures and so on are not good enough to be abe to code and prefer using ready-made devices. Does your approach allow a workflow like step 1 - download a program that casts something to your device, step 2 - buy a ESP32, step 3 - download a program that flashes your code to ESP32, step 4 - connect ESP to PC through USB, and flash it, step 5 - done? Or even better - buy online preprogramed device and download a program to cast something there - and start using it?

@WindLighter I would love to sell these as a pre-programmed product someday but right now that’s outside of my scope. For now I will be keeping the project open source so someone can simply buy the hardware and install my pre-written code. Anyone attempting this will still need the basic knowledge of soldering and 3D printing as well as setting up the Arduino IDE but all of those things can be learned for free on KZfaq already so I don’t go into the details. I am planning smaller projects for the future that will be more practical to sell and ship from my own store but we’ll see how it goes.

Sometimes I have to connect LMCSHD multiple times to get it to work right. If your matrix dimensions don’t automatically get set then close the pop up and try connecting again. Once the dimensions autofill it should work!

Go to the library manager and make sure you’ve installed the websockets library

Price mostly but I also like the pixel aesthetic. P3 or P2 panels will happen eventually if I can make the money back.

@@TheTechRandom Thank for reply. I am doing my project, raspberry pi 3 and matrix led. If that looks okay, I will just share with short video although that might be lame cuz it is quite old and nothing new.

Everything is customizable on the website so you can get just the frame for a really good price or you can choose from a wide variety of desktop styles and colors. I encourage you to check it out and see if there’s a configuration that fits you needs and budget!

I go into more detail in the full video

If you don’t like the grid lines you don’t need to use them. If you have a diffuser that’s 1 cm away from the LEDs without the grid then the colors will blend together and it will look like a blurry monitor instead of a pixel array.

I’ve used WLED for small matrices and all of the lights in my house. The effects are great as well as the controls, but for this project I want to specifically mirror a PC display so that’s why I’m doing it this way instead!

WLED doesn’t support screen mirroring but there are many other advantages to it. I want this project to be scalable for as many applications as possible so screen mirroring is an important part of that.
