Very nice and easy to follow projects. I discovered these panels and their possibilities with your video on the scrolling text for smarter everyday. Your videos have helped me going from knowing nothing to being able to modify the base code to fit my needs. I added wifi manager to the scrolling text base code and also the possibility to do OTA updates which I think it’s a great feature as you can update code with the panel still mounted in your wall!

Great vid! I've got some 38 pin ESP32s on the way. Reading through some of the comments and answers here and: You mentioned in one of the comments that this board could power a 64x64 matrix without a power supply - is that as simple as soldering up the 5v and ground pins? From some research i've done (I'm a complete beginner mind you) you'd need to have a 5v 4a power supply to run the 64x64s at max brightness. Is it possible for the board to do this and power itself? and... how can that be figured out? Thanks!

I’m trying to use a hologram fan as an odometer for my motorbike, I need a way to encode and render the sensor readings to a video and then to input video of the hologram, so far I’ve considered using esp32, is it capable of taking odometer sensor reading and rendering two block numerals that may rotate slightly I.e.isosceles scaling to create a depth of field effect amongst the invisible display?

Hi Brian, is there a limit on the amount of panels that can be used i.e. could I use 4 panels in a square to make an extra large Mario clock? If so, apart from 3 extra panels, what other components would i need? Thank you

@BrianLough Рік тому

Is there a limit, yes, the esp32 eventually doesn't have the memory to handle a large amount of panels, but 4 panels *should be* ok. Is it possible, yes, but it will be significant effort. There are a two different issues that need to be addressed. 1) physically assembling the panels. Wiring is not too big of an issue, ribbon cables usually come with the panels and you plug the trinity/esp32 into the first one and then plug the ribbon cable in to connect the other ones together. Powering the panels is a bigger concern, the trinity probably can't power the 4 of them, but if you supply an external 5vs to the panels that would be fine. 2) the software. The first issue is that the libraries default is to consider the panels being in a long line (4*1) but you are looking to put them in a grid (2*2). The library does support this, but you'll have to read the documentation on it on the GitHub page The code would also need to be modified to handle a 128*128 screen, it's currently written for a 64*64

@hankpaxton5585 Рік тому

Built this with your ESP32-Trinity and works great. I remember seeing somewhere that there is the ability to use an ambient light sensor to automatically dim the display. However, I can't find this again. Could you elaborate on this?

@BrianLough Рік тому

Great to hear! The LDR (light dependent resistor) should have come with your Trinity (it's a red and white thing). it needs to be soldered onto the top right of the board, above the esp32 module. It's not added as part of assembly to allow users to route it to the top of the panel or somewhere that makes more sense than pointing directly out from the back of the panel. After that It's possible once the software supports it, which isn't the case with either of these examples at the moment. Here is an example showing how it could be added to a sketch though: github.com/witnessmenow/ESP32-Trinity/blob/master/examples/TrinityFeatures/LDRAutoBrightness/LDRAutoBrightness.ino

@BrianLough Рік тому

For 1), this is a problem with some panels where they physically have the wrong colours connected, it's something that will need to be fixed in code so you'll have to install the version from GitHub (not webflash) Fix for it is described here: github.com/witnessmenow/ESP32-Trinity/blob/master/FAQ.md#my-colours-are-mixed-upnot-right For 2) you should be using a string to get the correct time, so for me in Ireland it would be "Europe/Dublin" for central European time it could be "Europe/Paris" or something

In theory yes. once the only difference is the size of the LEDs it really shouldn't matter. There are some displays that are configured differently though so there is a chance it won't be the same. The trinity is also really designed to work with p3 panels from a physical size point of view, but it would hopefully work out.
