Making a 5*5*5 LED Cube without led driver

All you want to know is how to make a led cube.OK lets DO it.




 Parts list 

To make circuit

  1.  PIC18F877A
  2. LED(any colour)                       -125
  3. 330R                                          -10
  4. Vero board                                 -1
  5. Circuit wire
  6. 20Mhz crystal                            -1
  7. 22pf                                            -2
  8. 7805                                           -1
  9. 10uf                                            -1
  10. 1uf                                              -1

To make the enclouser

  1. Perspex sheets.
  2. Black coloured formica sheets.
  3. Super glue.

Making the LED matrix


  • First you have to  place led bulbs in a proper way to solder them.To place leds in equal distance I made a soldering jig using thin plastic sheets.You can make it also using wood. 
  • Then you have to solder leds layer by layer.You must ensure that all the leds are working properly before soldering.
  • You must bend each led lead as follows in order to solder easily.
  • After soldering all five layers you have to mount them one by one.First layer should be mounted on a pcb as shown below.

You can easily make the bottom pcb by following link

  • All the layers should solder one upon one.


  •  Number the cathods of leds



I used a floppy interface cable to connect the led cathods with the circuit.



  • Anode pin of each layer(five anode pins) should be connected to the floppy interface cable.




The most important thing you must know is you have to ensure all the leds are working properly.It is hard to replace leds after soldering.

Making the brain


 I make the circuit on a vero board.I'll give you the proteus schematic of my circuit.If you like you can make your own pcb.

 You need no any led driver to implement this led cube.I made my cube without any led driver because I couldn't found any led driver in local market.But programing this cube is more complex.I programmed the pic using microc pro v3.6.

Here is my code.I think it is hard to understand what I have done.But you can start to program it by simple program.Then you can go through difficult ones.

  2. Wow.....
    this is really cool machan.......
    I was also wanting to make my own led cube of 5*5*5....
    very helpful
