Radioactive Decay Seeded Random Number Generator

Images Scientific Instruments offers a radioactive decay-based random number generator.  It is available both fully assembled and as a kit.  This project characterizes the "randomness" of the device output.


"Random" number data acquisition setup.

Random Number Generation via the RNG-01

Design Inputs:

  • Arbitrary sun gear pitch curve, lobe and tooth count. (Sun gear is currently constrained to be radially symmetric with an integer lobe/tooth-count ratio)

  • Circular planet gear radius and tooth count.

  • Sun/Planet orbit ratio.

  • Gear tooth profile;  Involute, circular, arbitrary or null (pitch curve only)  

Design Output:

  • 2D gear profiles for sun, ring and planet gears in DXF-format.
