No, I don't have a blog. These are just my private projects that I make for my own use. I am working as a software developer and learning electronics as a hobby.
The backlight is going to be a box supplied directly from AC, connecting up to 6 strips of individually addressable WS2812 RGB LEDs, providing up to 10A at 5V (50mA per LED == 200 LEDs at full power). It will be connected using galvanically isolated Full-Speed USB to the PC.
For now I will have some pre-programmed sequences but I plan to make a piece of software that will make it possible to match LEDs to the borders of image on the screen though I have no idea how to do that at the moment.
I've also been playing with WS2812 LEDs as ambient/halo lighting around my monitor. I'm using a cheap ESP-32 dev board to allow control from my phone via WiFi even when my computer is asleep. I went much smaller though - only 16 pixels, powered by an old phone charger.
This works for now because my primary use-case is ambient lighting when the room would otherwise be dark. I'm planning to build some larger-scale higher-density light panels to provide more illumination for those dark winter days.
