Is it possible to retrieve raw generated bits ?

[Andréas LIVET]

Thanks for your quick reply,

Don't know much about hardware biais and electronic, but will definitely
investigate.
I think I found something more recent and quite similar to the circuit you
were refering :
http://robseward.com/misc/RNG2/

I'll maybe try to build one myself :).

Greetings,
Andréas
