Beetlejuice Sign

Beetlejuice - Beetlegeuse - Betelgeuse sign I created derived from Max Corbetts design found on youtube. My version uses an Arduino Nano with 3mm leds, 2 - ULN2003AN transistor arrays and 5v USB power. In order to get everything to fit I had to remove the USB connector and communications chip off the Arduino.

I CNC'd mine into MDF but it could be printed with a red filament. It might have to be painted on the inside to prevent the light from bleeding through translucent colors.
