Holoprojector OLED Display

The Holoprojector OLED Display is a modification of a Ftlhy standard holoprojector to include an Adafruit 0.96" OLED and a 12x Neopixel ring.

Parts List

This is a list of the parts used

1. BobC Holoprojector
2. R2-D2 HP Slip Ring Mount
3. Adafruit OLED Breakout Board 16-bit Color 0.96" w/microSD

4. Adafruit NeoPixel Ring 12x

   The RGBW versions look to be compatible in size

5. 12 wire slip ring

6. Window Film One Way mirror (non-adhesive)

   You can put the rest on your windows :-)

7. Any kind of clear acrylic adhesive. I use Weld-On but I'm sure other types work just as well
8. 3mm sheet of clear acrylic for laser cutting
9. Arduino Mega or Mega 2560 Pro (Embed) 5V
10. Crimp ends and crimpers for the slip ring.
11. Heat shrink tubing and some wire wrap for the finishing touch

    frontHolo.play("Leia.bd2");

By default the Holoprojector display provides 3 movies, but you can upload additional ones:

Leia.bd2: Tantive IV Leia recording:

Plans.bd2: Deathstar plans

R2.bd2: R2 cartoon
