(another) external Lighting Node Pro for back of screen


Recommended Posts

Yep, another person doing this. I'm only going to talk about things I don't think I've seen before.


I mounted the LED strips by gluing magnets to the back of the screen: https://imgur.com/gallery/4PltYqs


This means that if I find an SDK app that would work better with the light strips arranged in some other order I can just change them around.


I also cut off the SATA power connector. I used a multimeter to work out which pins were connected to which wires, then wired the two ground wires and the +5V wire to an external power supply and left the +12V wire unconnected: https://imgur.com/gallery/SEHrdWi


This is quite a lot less bulky than using a complete PC PSU or even using a 5V adapter with a SATA connector on it. It seems the +12V isn't necessary, at least for my setup with only 4 LED strips.
