I have been working for a while on a LED Panel Project. The idea is to have a low cost LED Panel assembled from scratch.
As I go thru the phases of the project, I will be posting some photos, videos and documents in order to explain with details how it was built.
Now I have a very simple 1m x 0,5m panel, which is composed by 20 lines of led strips (1m each) with 30 leds on each line. As I am using the old fashion led strips, each IC controls 3 leds. Therefore, in practical terms, I have a LED panel that is 10x20 (X,Y). It means 600 leds, but 200 as the software is concerned.
I am using Jinx and an Arduino Uno board to drive the LED Panel.
Next step will be to drive the panel using an ESP32 DEV KIT board and have a 50cm x 25cm LED Panel with a better resolution (30x17 leds). Once it is done I will try to drive at least 4 of this panels with parallel output and the Resolume Arena software.
Let´s see if I can get it working…….
I have managed to have the panel working with ESP32 on a WiFi configuration. I am using two DMX universes. I am still using Jinx because it has a simpler user interface to work with.
I have bought a couple of 5-meter WS2812b LED stripes (60 LEDs per meter). It will give me a 50cm x 30cm panel with 600 LEDs (30 x 20). For 600 LEDs, I will have to use four DMX universes. As soon as I have it assembled, I will post some pictures. On this one, the LEDs stripes will be placed on the back of a frame with squared holes, so the only thing we will see are the LEDs. The strip will not be visible. For testing proposes I will use a black EVA frame. Same sort of metal or wood (with waterproof treatment) will make the final version, but in order to do that, I will need some support from my local FABLAB.
The idea is to have four of these panels as a starting point (1 m x 0,6 m). If the resolution of this panel is acceptable, then I will keep growing its size up to the point of a 3 m x 2m panel.
Once I have the 1m x 60 cm LED panel working fine, I will post all the information regarding the material used, code and software configuration.
Phase 2: I have managed to have the ESP32 and the Jinx working fine on a 10x10 panel. I am using a 10x10 panel because I have noticed that when I configure the ArtNet output device on Jinx, it locks in 512 channels. That was expected, because one DMX universe has 512 channels. My 10x20 panel has 200 LEDs which means 600 channels. I will work on the universes to see if I can have my 10x20 panel fully working too with ESP32 and Jinx.
Once I have it working, I will try to use the Resolume Arena with my ESP32.
