Random Number Generation [closed]

I have a need for true random number generation. I've been looking at a number of hardware solutions. Does anybody have any solid experiences with these? Any recommendations?

I don't think I can make a convincing argument for a lava lamp hack. ;)

Solution 1:

We once bought a Protego SG100, but they hadn't released the Linux driver when we needed it so we never got around to using it. It looks like they have some newer products with various drivers now.

Solution 2:

Is there such a thing as a true random number generator? Random.org uses atmospheric noise to generate a random number, just need a really really long antenna.

Solution 3:

Here is one idea:

"True random numbers from Wi-Fi background noise"

Solution 4:

Unless you need hundreds of billions of random #s, the easiest thing to do is just use random.org. You can purchase blocks from them if you go over the free allotment.

People have come up with some rather unique solutions to gain "street cred" with their random # generators (particularly online gaming sites). This random dice roller is my personal favorite ... generates 1.3 Million random dice rolls per day.
