I'm the dork making them by hand in SF :) It's just a fun hobby. I'll
make 10 more soon...
As you found, OneRNG is open-source and open-hardware. I strongly
recommend it for nearly all applications. Coupled with a solid CPRNG, it
generates all the cryptographically secure key data you will ever need.
Being fully open-source is extremely important for a TRNG. NeuG
<http://www.gniibe.org/memo/development/gnuk/rng/neug.html> should get an
honorable mention here. However, the engineering and theory behind OneRNG
is stronger, and OneRNG includes the schematics and board layout, and even
a bill-of-materials if I remember correctly.
A more popular alternative is TrueRNG
but even though the creator promised to make his code and schematics open
source, he never delivered. We simply don't know if it is any good.
Back to this thread: The beam splitter is cool :) An open-hardware version
would be a welcome development, IMO.
