[@sebastiansombra]

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! Thanks for sharing your projects

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!

hello Brian, I did the editing but I have 2 problems: 1) blue and green are reversed. 2) impossible to configure the time for europe, what is the right command to put in the WEB interface. I tried UTC +1:00, UTC+1, UTC 3600, UTC Europe/brussels Thanks for the video

[@BrianLough]

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

[@hankpaxton5585]

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]

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

[@jimmymach6588]

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]

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

Hi! Im currently using the Tetris clock but the constant brightness is bothering me, especially at nighttime. Are there any plans to integrate a brightness setting?

[@bigtst36]

I got two of the Trinity boards and they come with an LDR. You have to solder them to the board manually using lead wires so that you can position sensor where it needs to be. Haven't wired mine up yet, so not sure if works or not.

[@BrianLough]

It is possible, but it's a little complicated to be honest. Check the GitHub page of the i2s matrix library for details

[@P.A.T.]

Hi! Where can I find that kind of matrix?

[@BrianLough]

Hi Paul, the most convenient place to get everything is Makerfabs, they sell the trinity and the panels (and they test that panels work with the trinity) www.makerfabs.com/esp32-trinity.html Scroll to the bottom of that page to see the panels

[@jasonnation6615]

How would I go about using the esp32 as a simple wifi antenna for my laptop? for example if my wifi card inside was to fail, could I use the esp32 to connect and surf?

[@KrantzThe]

Yes, but speeds would be lower than before, about 10-15mbps. We have implemented this in work, connecting esp32 over Ethernet and then using the ESP32 over wifi to an access point. Your keywords to Google are PPP and LWIP bridge.

[@shinysquirrelclub]

doesn't your trinity have a voltage regulator?

[@BrianLough]

It does for the esp32, but not for the panel, they take too much power to have a regulator for them.

Hello. I tried the Mario clock project and the clock is two hours behind. For example I entered US/Hawaii as my time zone and saw the incorrect time. I reinstalled the code and tried Pacific/Hawaii and got the same 2 hour delay. Does anyone know what could be wrong? Thanks!

[@goranjosic]

To be honest, neopixes matrix look much better than these displays - somehow the lighting is stronger, as well as the colors. (Of course neopixel uses much more power, but still) These displays would be a good solution if there were many of them, enough to form a screen of at least 200x200 pixels.

Are you using a Trinity or your a diy solution? It sounds like there is a problem with your e pin, hopefully that narrows it down!

[@toastknusprig9622]

@@BrianLough Hi thanks for the answer, it really seems to be the e pin, but even with a secure connection, im only getting pixel flickering if i twist and turn the cable. I think the cables interfere with one another as when i move them, they give different signals. To be fair, the cable management is pretty chaotic, ill try using shorter ones and lay them parallel to one another.

[@dalewhitmore143]

Can we use a P1 board instead of the p3?

[@BrianLough]

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.

[@dalewhitmore143]

@@BrianLough ok thanks very much. Also is there any other boards that work as I can't find a trinity board here in Australia or on aliexpress

Sorry but Makerfabs is the only place stocking the trinity at the moment. As I mention in the video, any esp32 could work if wired appropriately , once it has 14 available gpio. There are some alternative devices for controlling matrix boards like one made by adafruit, but I'm not aware of one that will work with these clocks.
