A nibble is equivalent to half a byte or 4 bits, encodable on one of the 6 faces of a die.
A 6-sided die can easily be built using 6 sonobe origami modules, 2 dice can be used to store 8 bits of data for the paper computer. This is an original idea from Maleza.
The 6 faces of the dice are as follow:
| sA | sB | sC |
|---|---|---|
| sD | sE | sF |
Hex table
Here is the 16 possible values that can be expressed with the rotation of the die.
| 0 sA | 1 sB | 2 sB | 3 sC |
|---|---|---|---|
| 4 sB | 5 sC | 6 sD | 7 sE |
| 8 sB | 9 sD | A sC | B sE |
| C sC | D sE | E sE | F sF |
Each face can express a specific number of values, here are all the values that can be expressed for each side.
| Face | Values |
|---|---|
| sA | 0 |
| sB | 1, 2, 4, 8 |
| sC | 3, 5, A, C |
| sD | 6, 9 |
| sE | 7, B, D, E |
| sF | F |
The nibble dice cannot be used to generate random values, as some sides hold a higher number of results than others.
