Уязвимость LED-панелей
Здравствуйте, читатели Хабра. Хочу поднять важную тему, о которой сейчас практически не говорят, — уязвимость LED-панелей. Хотя технически это сложно назвать "взломом" в классическом смысле, речь идет о возможности подключиться к LED-дисплеям и изменить отображаемый на них текст или изображения.

That's some #NextLevel #AssholeParking but I've to admit they look cool with those #lights - not shure if a #Trithium ring or #LED or #phosphorescent...

Inspired by Youtube's Patt Vira, I implemented the Reaction Diffusion algorithm in C++ on my testbed for my 64x64 matrix. Next step is to port this to my #esp32 #microcontroller and have it output directly on the #HUB75E #LED Matrix display.
In my implementation, I have three different rendering modes
Every 0.5 seconds I add/subtract a bit of B value to keep the sim alive, and reset the entire thing if the balance goes over 50%
Week 1025 - scanning and planning
@amcewen tidies up the move to a newer version of #ESPIDF; @defnetmedia looks at a website refresh; @huffeec does some #3Dscanning and some rather sweet #3Dprinting and #LED work as we look towards this week's #OHS2025
