> I salvaged some 13” LCD displays from old laptops and found additional matching displays on ebay.

The LCDs were taken from old disused equipment.

And the board was disused equipment too, it seems.

I find this kind of reuse very inspiring. Once I no longer need my old laptops, I feel like it might be fun to do something similar instead of shipping the whole thing to a recycling plant. You could even use LCDs that have dead pixels or other defects.

You could argue that requiring a 35 W LED lamp is wasteful, or the power used by the SoC (10 W max), etc., but together that's still about as much as a standard incandescent lamp.
