 For the 64 columns I used a [[http://​www.nxp.com/​documents/​data_sheet/​74HC_HCT595.pdf|74HC595 8-bit serial-in, serial or parallel-out shift register with output latches; 3-state.]]. Because there is never more than one level on at any time, we do not need mosfets or transistors to boost the power of the outputs. We do need to connect 8 74HC595 together to get 64 outputs. For the 64 columns I used a [[http://​www.nxp.com/​documents/​data_sheet/​74HC_HCT595.pdf|74HC595 8-bit serial-in, serial or parallel-out shift register with output latches; 3-state.]].

 +====== Bringing it all together ​ ======
  
-These are the principles used in creating the LED cube, the details ​will follow...+The design, build and software are made and put together is described in the following paragraphs. 
 + 
 +===== The driverboard ===== 
 + 
 +The ''​driverboard''​ is the PCB which connects the Arduino to the LED cube.  
 +I designed the PCB in a program called [[http://​www.cadsoft.de/​|Eagle]]. This software is really good for designing PCBs and schematics but unfortunately the free version has a limit on the maximum size of the PCB you can design. So in the end I actually made the board on a ''​PCB Prototyping Board''​ Actually [[http://​www.okaphone.com/​artikelen.asp?​id=977&​groep=604|this one]]. 
 +^The schematic^^

 + 
 +The finished ''​driverboard''​ in the end looks like this:

 + 
 +===== The LED cube ===== 
 + 
 +The construction of the LED cube is a very tedious and time consuming part, and also the most visible part. So take your time and measure twice, cut once... 
 + 
 +Some details of the construction:​

 + 
 +===== The Software ===== 
 + 
 +The software is still a work in progress, as it should be. Because there are always more effects and animations to create if you have the power over 512 LEDs on your fingertips... 
 + 
 + 
 +These are the principles used in creating the LED cube, the details ​might follow ​some day... If you have a question regarding this project, you could try sending an e-mail. I might even answer if the question is right.
