    I would love to know too

  • Tutorial - Random Number Generating Geiger Counter | about 4 years ago

    To test the randomness of the data gathered using this device and a sample of Uranium ore, I gathered 4 groups of 65536 bits each.
    Here are the results:
    Group1:
    Bit 0 found 31922 times
    Bit 1 found 33614 times
    Mean: 0.512908935547
    ChiSquare: 43.6838378906 with a DOF of 1 mean that it is not a valid random sample
    Group2:
    Bit 0 found 31885 times
    Bit 1 found 33651 times
    Mean: 0.513473510742
    ChiSquare: 47.5884399414 with a DOF of 1 mean that it is not a valid random sample
    Group3:
    Bit 0 found 31960 times
    Bit 1 found 33576 times
    Mean: 0.512329101562
    ChiSquare: 39.84765625 with a DOF of 1 mean that it is not a valid random sample
    Group4:
    Bit 0 found 31982 times
    Bit 1 found 33554 times
    Mean: 0.511993408203
    ChiSquare: 37.7072753906 with a DOF of 1 mean that it is not a valid random sample
    What software do I need to reprogram the on board Atmega168 to improve randomness? I would like to implement the algorithm that takes 4 events instead of 3 to generate a bit.

No public wish lists :(
