 Hello friends! I hope you came well trough the holidays. After a lengthy editing session the hopefully watch-worthy video is done. If you like one of these programmers the Tindie shop listing will be online tomorrow and I'll provide you with some coupon codes beforehand.  What might be even more interesting is the code. Even though it's not this videos focus, but I took some time to finally implement the I2S serial mode in my ESP32Lib which is also used to feed the LEDs. There is a basic class to access the LED array for now but that will be extended by the graphics interface used by my VGA stuff. The huge advantage of that is that it uses a DMA ringbuffer and all CPUs are free for other stuff. There will be a in-depth video how the effects shown work and how the library can be used properly once it's cleaned up and uploaded.

Now I'll hack quickly a game pad support for my new mini console so I can upload a unscripted update video before the competition on hackaday ends on Tuesday. That sounds like very optimistic Elon time planning but I hope it works out. Until then Enjoy!

ESPCam Programmer & LED Wall Effects

In this video a cheap ESP32 camera is interfaced and used to display real-time video on my huge ping pong LED wall. With some additional video processing nice visuals and interactive animations are created. A custom programming circuit is used to simplify the programming of the ESPCam. programmer: ...soon... code: ...soon... Links to the parts (affiliate links): ...soon...

Trademark bitluni video! The (almost) realtime LED wall effects were super cool. Absolutely loved the one with image repeating in different colors. It'd be great fun to reproduce this even with a small scale panel. Any plans to recreate the LED panel like effects through VGA by any chance? If it'd even be technically viable, using big rectangles in place of LED's?

Bitluni does it again, and again, and again. Very cool project.

Sure, the LED interface of my library will implement the graphics objects. This means all the graphics will be transferable to VGA and PAL (hopefully)

bitluni, very cool! I wonder if the camera has an IR filter that could be removed (or does it even have one to begin with, tbh haven't tried yet?). Then it could be possible to get the camera to work even in pitch dark using IR light. :)

That would be cool for surveillance... Maybe the interwebz has some info

I was thinking more on the LED matrix animations working when it's really dark. :)

bitluni

It would be cool to ONLY let ir pass to the camera so the wall wouldn't cause feedback... Great idea!
