This a great, minimalistic, LED name sign created using a simple setup of plexiglass, LEDs and some cool extra features. Â The author makes the project more complex by throwing in a microcontroller to the mix to change the colors, but you could easily wire up a simple LED circuit without the microcontroller.
- Don’t Miss: Make LEDs Thump to Your Music
Basically, he took a sheet of Plexiglass and mounted it on a rail of LEDs. The LEDs would normally shine straight through the Plexiglas and not create the glowing effect shown above but because the outer edges are scratched, the light is visible and the sign becomes illuminated the light was trapped in the engravings and thus illuminated.
Although he used a homemade CNC Machine to engrave his name, you can use a Dremel and a steady hand to accomplish the same thing. Â Or, send the plexiglass to be engraved professionally if you have extra cash. Â A simple, fun weekend project with beautiful results.
