This video explains how to make a one-piece DIY concrete waterfall countertop with an inlaid river of flowing LEDs that cascades over the waterfall edge (using neopixel LED strips).

This is the first of two videos for a mancave makeover at a friend’s house. Check out part 2: https://youtu.be/-RbUXryaz74

The countertop is made from a glass-fiber reinforced concrete (GFRC) concrete mix, which is pre-cast in a melamine form. I made the mix from scratch (recipe links are below). I mixed 280 lbs of the dry materials (including powdered pigment) all at once, so the color would be consistent. I used 40 lbs for the face coat, and the remaining in batches for the back coat with glass fibers.

I used an off-the-shelf LED controller that has MUSIC REACTIVE modes, chasing modes, and solid color modes, with an RF remote, to control the WS2812 LED strips. (https://goo.gl/mC8B5j) The LEDs are covered by a smoke grey transparent acrylic sheet, which is inlaid so it sits flush with the concrete countertop.
