It is possible no one replied because I am WaywardGeek, and I'm on this
thread. That's too bad, because I would love to hear opinions on my TRNG,
especially negative ones. I'd love to hear about the flashing red lights
:) Don't worry, I have thick skin and take negative feedback well.
There are some negatives that I know about. In particular, no EMI
shielding means a nearby radio might determine the 0's and 1's from the
device. One user concerned about this wrapped it with aluminum foil, and
used the extra shrink-wrap over the tin-foil, but I like to see the board
and choose to live with the EMI risk. Another issue is the architecture is
new, and not time-proven. For stronger protection, consider the OneRNG.
It is my current favorite for production needs. I actually carry this one
in my pocket, so I prefer its smaller form factor. However, only a
ridiculous geek would carry one of these in their pockets :)
