Dice Rolls From the Beginning of Time
Generating random numbers might seem like a trivial task, that is until the numbers need to be truly random for cryptography or security reasons. When that's the case, it turns out that these numbers are really "pseudo-random" and follow a predictable pattern. Devices that can produce truly random numbers often do it by sampling random events in the real world rather than relying on a computer to do it directly, like this machine which simulates a dice roll by looking at the cosmic microwave background radiation.
The cosmic microwave background radiation exists in the infrared at the farthest edges of the observable universe as a remnant of the big bang. It's an excellent source of randomness, but tapping into it poses a bit of a challenge. For this build, [iSax] is using an old Soviet-era Geiger tube to detect the appropriate signal, and a Nixie tube to display the dice roll. After the device detects two particles from the Big Bang, the device measures the amount of time that passed between the detection of both particles and uses this number to calculate the dice roll.
While it takes a little bit longer to roll this dice than a traditional one since it has to wait to detect the right kind of particles, if you really need the randomness it can't be beat. It certainly works as dice, but we can also see some use for generating truly random numbers for other applications as well. For some other sources of random inspiration be sure to check out our own [Voja Antonic]'s deep dive into truly random number generation.
Random Numbers From A Smoke Detector
The quest for truly random numbers is something to which scientists and engineers have devoted a lot of time and effort. The trick is to find an unpredictable source of naturally occurring noise that can be sampled, so they have looked towards noisy gas discharge tubes or semiconductor junctions, and radioactive decay. Noisy electrical circuits have appeared in these pages before as random number generators, but we'd be forgiven for thinking that radioactive decay might involve something a little less run-of-the-mill. In fact we all probably have just such a device in our houses, in the form of the ionisation chamber that's part of most household smoke detectors. [Lukas Koch] has built a project that shows us just how this can be done.
A smoke detector of this type uses a metal shell to house a tiny sample of radioactive americium that emits alpha particles into the space between two electrodes. These ionise the air in that space, and the detectable effect on the space between the two electrodes is increased when ionised gasses from smoke are present. However it can also quite happily detect the ionisation from individual alpha particles, which means that it's perfect as a source of random noise. A sensitive current amplifier requires significant shielding to avoid the device merely becoming a source of mains hum, and to that end he's achieved a working breadboard prototype.
This is still a work in progress and though it has as yet no schematic he promises us that it will arrive in due course. It's a project that's definitely worth watching, because despite getting more up-close and personal than most of us have with radioactive components, it's one we're genuinely interested to see come to fruition.
Of course, we've seen smoke detectors in more detail before here at Hackaday.
