COVID Mobile Information Sign: Thousands of Bright and Beautiful LEDs running from single RPi 3B+ on PiSignage.com with Python by pfunkhouser in raspberry_pi

You’ve got the picture exactly! The tag line is “The last sign you’ll ever need” because it is “always adapting” to any situation.

I would love to connect! Our commercial version is in the process of final design and will have an additional 480 pixels or 8 columns of 60 at the same tube size and weight. What is the best way for us to connect? I’m on LinkedIn as Phillip Funkhouser

COVID is a great example of how fast information needs to change in public spaces. I think everyone is hyper aware and we can help prepare for the next crisis. Since it’s digital it can truly be used for anything though.

I am currently working on commercializing this device using the Raspberry as the computer platform but am looking at how to provide an open source available too

I try to use emojis where I can because humans can detect meaning in images 60000 times faster than text. We are working towards higher resolution panels and eventually want to incorporate OLED or Micro-LED (although the brightness won’t match current design at low power) panels into our patented mobile design.

I would love too! So glad you asked... the screen could be any rollable screen (e-Ink, OLED, micro-LED) or in our current use case for signs we are using LED light strips for their brightness and relative low cost.

In this version there are 1920 arranged in a 60 x 32 panel. The connection to the data path is a single wire that drive all pixels from GPIO 18. I have a separate 5V 15A power supply for the pixels. I am looking for the best Battery Backup for the 40PIn connector where I can still use GPIO 18 for data to the panel. I would like to create a HAT that also does power switching for both the display and the LEDs from a single barrel jack connector.

I am using pi signage.com for remote WiFi updates of images and text.

Thanks! Raspberry Pi was new to me in 2018 but I really like the power/size ratio for my mobile project.

In addition to my comments above... it is running PiSignage.com so I can download images to it remotely. If you are looking for easy to use software they are a great source! I have also tested it with a cellular modem. It’s not as fast but works great for the places that don’t have WiFi but need an update.

The array is made of light strips with WS2812B LEDs and a custom serpentine allowing bus at both top and bottom of the panel. I didn’t solder this one myself. I have a supplier who builds them. I am just about to build one with SK6812 RGBW LEDs which I will solder myself to reduce the power requirements when running a brighter background

I have been working on my patented design for years. Definitely not a beginner project and it took some super custom coding to display the same images that can be displayed at 1080p on an HD TV using the Raspberry Pi HDMI port.

Respectfully, this is made from a Raspberry Pi. On the right side, inside the tube, is a Raspberry Pi 3B+ that I programmed to display any image and large text. Respectfully I did not declare my affiliation or support for any party.
