I made an electronic message board using Raspberry Pi and RGB-Pixel boards.
Something similar to my virus simulator but with a horizontal layout. I can display various information messages a bit like an airport arrival board or a share price ticker, or a daily inspirational quote.
I also made a web-submit page to send messages directly to the board from anywhere on the planet.
Or simply use the app below which I built with Anvil for python.
It also gathers the data from the Solar Panels and displays how much of the house electrics are being covered by the solar panel’s energy. It is the green line at the bottom showing 100% of house electricity being supplied by the solar panels.
Another long term project…with many potential uses, none of them critical for life on earth.
