A cheap USB camera would make a good source.
The cheaper the better, too. Pull a frame off,
hash it, and it's got entropy, even against a
white background. No lava lamp needed.
I sort of agree, but I feel cautious about recommending that people
use their holiday snaps. And then post them on lin

It should be doable as just a RNG device for a BOM of a few tens of USD.
There are at least of couple of SoCs on the market which advert
Does anyone know of a cheap USB random number source?
As a meandering comment, it would be extremely good for us if we had
cheap pocket random number sources of arguable quality [1].
I've often thought that if we had an open source hardware design of
a USB random number generator ... that cost

Is $7.59 cheap enough?

For that you get a USB audio adapter with mike jack, and
then you can run turbid(tm) to produce high-quality randomness.

The Lava Lamp Random Number generator (at http://www.lavarnd.org/)
generates true random numbers from the images of a couple of lava
lamps. Of course, as a source of randomness for cryptographic
purposes, it's useless because it's visible to everyone (though I
suppose it might be used for
