In this episode, I show off a custom laser-engraved acrylic license plate cover I modified with an ESP32 microcontroller to create dynamic lighting effects. You’ll see how I integrated it with LEDs for colors, wipes, fades, and even a flame effect. We dive into the science behind linear fiber optics and total internal reflection, plus explore how the etched design channels the light just where it’s needed.
Finally, we tackle the big question: is this legal for the road? We review both federal and state laws and examine the nuances that determine what’s street-legal.
