Collaborate Disseminate
Randomness is a pursuit in a similar vein to metrology or time and frequency, in that inordinate quantities of effort can be expended in pursuit of its purest form. The Holy Grail is a source of completely unpredictable randomness, and the search for entropy so pure has taken experimenters into …read more
Need a random number? Sure, you could just roll a die, but if you do, you might invite laughter from nearby quantum enthusiasts. If it’s truly, unpredictably random numbers you need, look no farther than the background radiation constantly bombarding us from the safety of its celestial hideout.
In a …read more
For the casual Monopoly or Risk player, using plain six-sided dice is probably fine. For other games you may need dice with much more than six sides, and if you really want to go overboard you can do what [John] did and build electronic dice with a random number generator …read more
Hackaday editors Elliot Williams and Mike Szczys highlight the most delightful hacks of the past week. Need a random-number showpiece for your office? Look no further than that fish tank. Maybe the showpiece you actually need is to complete your band’s stage act? You want one of Tristan Shone’s many …read more
While working towards his Computing and Information Systems degree at the University of London, [Jason Fenech] submitted an interesting proposal for generating random numbers using nothing more exotic than an aquarium and a sufficiently high resolution camera. Not only does his BubbleRNG make a rather relaxing sound while in operation, …read more
Are you waiting for something that may never happen? Maybe it’s the end of your ennui, or the release of Half Life 3. While you wait, why not build a Godot Machine? Then you can diversify your portfolio and wait for two things that could happen today, tomorrow, or at …read more

Many languages feature a random number generator library for help with tasks like rolling a die or flipping a coin. Why, you may ask, is this necessary when humans are perfectly capable of randomly coming up with values?
[ex-punctis] was curious about the same quandary and decided to code up …read more
There’s not much time left now. If you’re going to put something together to give the youngsters some night terrors in exchange for all that sweet candy, you better do it quick. This late to the game you might not have time to do anything too elaborate, but luckily we’ve come across a few quick Halloween hacks that can get you some pretty cool effects even if it’s only a few hours before the big night.
As a perfect example, these LED “blinking eyes” were created by [Will Moser]. Using nothing more exotic than some bare LEDs, an Arduino, and …read more
We just wrapped up the Musical Instrument Challenge in the Hackaday Prize, and for most projects that meant replicating sounds made by humans, or otherwise making musicians for humans. There’s more to music than just what can be made in a DAW, though; the world is surrounded by a soundscape, and you only need to take a walk in the country to hear it.
For her Hackaday Prize entry, [Kelly] is hacking nature’s musicians. She’s replicating the sounds of the rural countryside in transistors and PCBs. It’s an astonishing work of analog electronics, and it sounds awesome, too.
The most …read more
Continuing on in our Encryption 101 series, we now look at what it takes to break encryption. In order for something as powerful as encryption to break, there needs to be some kind of weakness to exploit. That weakness is often a result of an erro… Continue reading Encryption 101: How to break encryption
