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.
RNG Information and Websites:
-
Planet gear radius & tooth count: 1, 12-tooth.
-
Gear tooth profile: Circular.
