Solder wire to LEDs
Solder wire to the bottom layer of LEDs (Rows=red, green, blue and Column=anode).
Build a base for the LED cube
It need a base for the LED cube to stand on. Again, I use my CNC laser cutter to make the base (Autocad drawing file: RGB LED CUBE COVER.dwg)
Insert wires into the holes of the cube.
Be patience, it was tedious work.
Tie up wires with cable tie
It is necessary to tie all the wiring neatly. Make sure cut all the wires in same length and put two square plastic holder in the middle of the base.
A plate for controller board
Attach a plate to the two square plastic holder allows the controller board sit on top of it.
Connecting LED cube to controller board
Prepare the header socket connectors, place a marking on pin 1.
Solder the wires that comes out from LED cube to the socket header connectors, the socket header connectors is then plug into the controller board.
Make an enclosure
I use 5mm thick acrylic to make a top cover for the LED cube.
Here is the bottom cover of the LED cube (Autocad drawing file: RGB LED CUBE COVER.dwg)
The power supply, power bank and Arduino is hide inside the bottom cover of the LED cube.
Done! Please enjoy the video.
