Infnoise
About the Infnoise PCB
Infnoise is an open source PCB design by waywardgeek, published on GitHub under the CC0-1.0 license. It is a 2-layer board measuring 34.9 × 12.2 mm, with 24 components from 13 distinct parts.
By type, the board carries 9 capacitors, 9 resistors, 2 switches and 1 inductor.

The world's easiest TRNG to get right
For instructions for compiling the and using Infinite Noise TRNG driver, go to the software sub-directory, and read the README file there. Both Linux and Windows are supported.
The Infinite Noise TRNG is a USB key hardware true random number generator. It uses what I call a "Modular Entropy Multiplier" architecture (previously Infinite Noise Multiplier or FireBug). Besides being simple, low-cost, and fast, it is much easier to get right than other TRNGs. It naturally defends against influence from outside signals, such as radio interference and power supply noise, making it simple to build…
