Am I reading this correctly? It sounds like the product is an LED matrix which requires third-party cloud servers to update the display? That doesn't sound right. Also, the author uses 2x 32x32 panels @$97 each as a price peg, but you can get a raw 64x32 panel from Adafruit (a quite expensive supplier) for $50.
I'be build pretty much the same thing using an esp32 an 3d printed enclosure and a small custom pcb. You can connect via websocket from a browser and upload images, text, ect. I've also managed to implement OTA firmware updates and a similar Wifi based setup as this product has. If anyone is interested I'm happy to put it on Github. https://photos.app.goo.gl/ajAbJ3fqqYQV5sd98 https://photos.app.goo.gl/PHzq1P7uWkJgAtP…
I'm lazy, but I plan to do the full write up and to open source everything. I use it to display pixel art, and during the night it automatically switches to the clock mode.
I love yours as well and it would be great if you can put the code on GitHub. Mine is using ESP32 as well (Adafruit's MatrixPortal M4). It is running Circuit Python though. I love it dearly and I played with an idea of making it as a product.

Love it! I did a similar thing, 64x64 pixels with a LED diffuser. Everything is packed up in the IKEA picture frame: https://imgur.com/a/cLXGWWd I'm lazy, but I plan to do the full write up and to open source everything.

I'll update my comment tomorrow with a GitHub link, just need to tidy up the repo first. This was my very first time writing c++, so the code is probably not the cleanest ;)

I would have bought so many devices like this, Vestaboard, etc. if they had a hardware local control option with completely open docs. I refuse to spend time engineering a data pipeline that’s dependent on someone else’s cloud service.
The only thing it doesn't have is a RTC, so I just polled a time server every so often.
Earlier quoted context omitted.
Is there a replacement firmware already available that allows local control? I feel like for all these connected hardware products, they should ship with an open source server and the phone apps that control them should have an "Server IP address" field in their iOS settings. Your company goes under? I just run your software locally and point my app to my local IP.
We're working on an example open source firmware. In reality though, it's not something the majority of our customers are asking for so with a 3-person team it hasn't been at the top of the list.

Using a pictureframe is a cool idea! I actually have an 64x64 matrix in my drawer that I havent used yet. Should you decide to open source your code I'd be very interested too.

Diffuser also makes a difference as the controller I'm using doesn't allow me to control the brightness. I should really write a blog post :D

It'll expand the audience immensely and probably be hugely profitable but I hate it.

Adafruit offers a starter kit with a microcontroller, 64x32 led matrix, and some other doodads for ~$70 ( https://www.adafruit.com/product/4812 ). It's really easy to tinker with. I made a clock that does some crappy visualizations and open sourced it here: https://github.com/kruffin/matrix_portal_gol It actually looks a lot like this Tidbyt (a box with a dot matrix). The only thing it doesn't have is a RTC, so I jus…
