RGB Uplighter Light: "Doobie Uplighter"

Wat?

The Doobie Uplighter is a nice slow color changing RGB light for indirectly lighting living spaces. It slowly goes through the RGB spectrum and provides the room with a nice chill atmosphere. The more Doobie Uplighters the merrier!

There are some designs provided but feel free to design your own. Creating new designs is easy, for example you can use the color change option in PrusaSlicer. I've also uploaded a special edition lamp which looks very nice when printed on an MMU.

Shopping list:

• Arduino Uno (or compatible microcontroller board), very easy to find, Arduino Uno, Leonardo or Clones go for € 8 - 25. They usually come with an USB cable included.
• CJMCU 8x8  RGB LED Matrix Panel (with 64 WS2812 LEDs), search for “CJMCU 8x8”, they go for € 7 - 35.
• 3 Wires ( 5V, GRND, Data), ideally with Dupont connectors, the length depends on the number of tubes you plan to use, check the assembly guide PDF for exact dimensions.

Order now,  printing will take 1 - 3 days :-) Your parts will arrive once you are ready for assembly.

Building Instructions

Start by printing every part once:

• Beamer and tube parts are best printed using the brim feature in Prusaslicer at 15% infill and a layer hight of 0,15 - 0,2 mm. The threads will be a little harder to screw if you use thick layers. Clean all threads for easy assembly, a drop of silicone lubricant will also help.
• The foot parts are best printed with a little more infill (20 - 30%) making the lamp harder to tip over.
• The diffusor is best printed in clear PETG, clear PLA will do. The lamp will work without, but it just looks nicer.
• Print the tube part as many times as you need, all my photos show 2 tubes, which works for me. Don't forget the brim.

1. Connect the Panel to the 3 wires and lead the wires down through the beamer, keep track of the wire colors you use for 5V, GRND, DIN
2. Remove the brim and assemble your tubes by screwing them together, mind the wires.
3. Assemble the foot top part, mind those wires!
4. Put your Arduino or compatible inside foot bottom part
5. Wire Controller to Board: 5V → 5V, GRND → GRND, Pin 7 → DIN
6. You might want to glue the Panel inside the beamer or the microcontroller board inside the foot bottom part.
7. Use Arduino SDK (or compatible) to upload "Doobie_Uplighter_Code".ino" to your microcontroller board. Notice that you can always change the code on your controller without disassembling the lamp.
8. Use an USB cable and power supply for your new Doobie Uplighter or plug it into your PC, TV or any other USB outlet.
9. You are done! Enjoy the calm chill ambiance lighting. 

Credits

I used the Adafruit NeoPixel library for Arduino. Adafruit has their own variety of a 8x8 RGB LED Matrix, which will fit if you clip the topmost pins in the beamer and use 6 small drops of glue. Check out https://www.adafruit.com/product/1487

The term Dooby Lamp was first coined by Big Clive (http://www.bigclive.com). Later the term Dooby Computer or Doobie Computer was used by his YouTube chat for any kind of blinking or color changing LED matrix assemblies of which there are a lot on his YouTube live channel. Doobie Uplighter consequentially combines slowly color changing LEDs and indirect lighting and is also a word play on lighting up a doobie.

Bruh!
