Now that LED strips exist, it’s super easy to make your own lighting. Case in point, YouTuber Darbin Orvar shows off her light cube packed between a couple of slabs on concrete.
The easiest part of the this project is wiring the LEDs to a USB port, which just requires a small amount of soldering. From there, the concrete is formed, then the shade is made from a polycarbonate sheet. The end result is a clever looking little light that can plug into any phone charger with a USB cable. Of course, you don’t really have to use concrete if you don’t want to, but the video provides a pretty good base idea for any number of different materials.
