i am on a project 8x8x8 LED cube and I am stuck on the value of register i should use.
Talking about single layer
I am using 2N5296 transistor for common cathode and 8 shift registers for controlling 64 anodes.The LED I have used are from robocaze.com which are 3mm Blue LED undiffused.
Now the problem arises between shift register and anodes of LED I need to connect resistor and I want to calculate its value.But I dont know that what amount of voltage and current are used up by the transistor and the shift register (74HC595).
If someone can help me figuring it out then I will be very thankful to him.

Transistor 2N5296
Shift Register 74HC595
Thanks in advance
