Just use a lava lamp.
- simias 13y agoOr a microphone sampling ambient noise.
- GotAnyMegadeth 13y agoAs long as the physical location of your microphone is secure...
- gonzo 13y agoOr a CMOS sensor in an otherwise perfectly dark environment. http://www.lavarnd.org/news/lavadiff.html http://www.lavarnd.org/news/lavadiff.html
- ape4 13y agoHow about a camera looking at the sky/weather. That's pretty random. (The attacker would have to float a blimp over your office ;))
- stephengillie 13y agoHow about this: 1. a die (D6, D20, etc) enclosed in a clear dome with a base that will pop and cause it to fly into the air and land. The base would ideally be made to pop electronically, maybe by a servo 2. a camera directly overhead the die which feeds into a computing device 3. OCR software that receives the camera input and outputs the number on the die
- oakwhiz 13y agoWhile Boggle sounds like an interesting method of generating random numbers, I think that a better way would just be to whiten the "random pulse train" output from a Geiger counter next to a weakly radioactive sample and send the resulting numbers over a serial link.
- DanBC 13y agoThat would be very slow source of random numbers. I wonder how well it would last over time? Assuming a normal (not precision casino) die, bought off the shelf from a high street store - would you be able to see any pattern in 1 million rolls? Would deformation of the popping base affect randomness at all? How about a webcam sampling "snow" from an untuned TV?
