Parts list

3D printed parts

  • 6x beam
  • 2x beam-w-hole
  • 2x beam-bottom (one symmetry !)
  • 2x beam-bottom-w-hole (one symmetry !)
  • 4x corner
  • 4x corner-bottom
  • 5x corner-cache
  • 1x corner-cache-w-hole
  • 4x panel-holder
  • 1x electronics-case
  • 1x electronics-case-top
  • 1x support

In doubt you can replace all beam variants by :

  • 8x beam-w-hole
  • 4x beam-bottom-w-hole (two symmetries !)

The no-hole variants use less material and are faster to print.

Hardware

  • 6x 210mm/2mm square one-way mirrors (or standard glass/PMAA with one-way film)
  • 24x M2 15mm wood screws

Electronics

  • 6x 80cm WS2812 LED strips (60 LEDS/m)
  • 1x Arduino Nano
  • 1x Bluetooth module
  • 1x capacitive touch button (20x15mm)
  • 1x 10A 5V power supply
  • 3-wire cable

Assembly

  1. Start building the cube from the top panel, taking care where you use beams with or without holes to pass the wires. You will use all beams and corner pieces and five panels, dont put the last bottom panel yet
  2. Cut the LED strips to lenght en solder the wires, I recommend using dedicated power lines for each strip but you can use a single wire for the data line
  3. Glue the strips to each side and pass the wires in the beams, all wires must output on the same corner. I recommend adding CA glue as the standard 3M tape is not adhesive enough
  4. Check that every strip is working correctly
  5. Put the bottom panel and secure it in place by glueing the four panel holders
  6. Glue all height corner caches

The following diagram shows one way to arrange strips (flattened cube seen from top).

Configuration

Edit the constants.h file according to your wiring :

  • PIN_LED output pin use to control LEDS
  • PIN_BUTTON input pin for the control button
  • BLE_RXD RX pin for the BLE module
  • BLE_TXD TX pin for the BLE module

Edit MAX_MILLI_AMPS according to the rating of your power supply (keep a safety margin, especially with cheap Chinese stuff).

Controls

The cube is controlled via Bluetooth and can received basic serial commands:

  • BRIGHT X(X=0-255) to change the brightness
  • BRIGHT+ to increase the brightness by 16
  • BRIGHT- to decrease the brightness by 16
  • MODE X to change the current mode, modes are:
    • RAINBOW
    • RAINDROP
    • PULSE
    • CYLON
    • CHASER
    • RANDOM
  • MODE+ to use the next mode
  • MODE- to use the previous mode
  • HUE X to change the current hue, huse are:
    • RAINBOW
    • RED
    • YELLOW
    • GREEN
    • BLUE
    • PINK
    • WHITE
  • HUE+ to use the next hue
  • HUE- to use the previous hue
