On Egyptian Pyramids And Why It’s Definitely Aliens

April 1, 2025 by Maya Posch 59 Comments

History is rather dull and unexciting to most people, which naturally invites exciting flights of fancy that can range from the innocent to outright conspiracies. Nobody truly believes that the astounding finds and (fully functioning) ancient mechanisms in the Indiana Jones and Uncharted franchises are real, with mostly intact ancient cities waiting for intrepid explorers along with whatever mystical sources of power, wealth or influence formed the civilization’s foundations before its tragic demise. Yet somehow Plato’s fictive Atlantis has taken on a life of its own, along with many other ‘lost’ civilizations, whether real or imagined.

Of course, if these aforementioned movies and video games were realistic, they would center around a big archaeological dig and thrilling finds like pot shards and cuneiform clay tablets, not ways to smite enemies and gain immortality. Nor would it involve solving complex mechanical puzzles to gain access to the big secret chamber, prior to walking out of the readily accessible backdoor. Reality is boring like that, which is why there’s a major temptation to spruce things up. With the Egyptian pyramids as well as similar structures around the world speaking to the human imagination, this has led to centuries of half-baked ideas and outright conspiracies.

Most recently, a questionable 2022 paper hinting at structures underneath the Pyramid of Khafre in Egypt was used for a fresh boost to old ideas involving pyramid power stations, underground cities and other fanciful conspiracies. Although we can all agree that the ancient pyramids in Egypt are true marvels of engineering, are we really on the cusp of discovering that the ancient Egyptians were actually provided with Forerunner technology by extraterrestrials?

Wrencher-2: A Bold New Direction For Hackaday

April 1, 2024 by Jenny List 44 Comments

Over the last year it’s fair to say that a chill wind has blown across the face of the media industry, as the prospect emerges that many content creation tasks formerly performed by humans instead being swallowed up by the inexorable rise of generative AI. In a few years we’re told, there may even be no more journalists, as the computers become capable of keeping your news desires sated with the help of their algorithms.

Here at Hackaday, we can see this might be the case for a gutter rag obsessed with celebrity love affairs and whichever vegetable is supposed to cure cancer this week, but we continue to believe that for quality coverage of the latest and greatest in the hardware hacking world, you can’t beat a writer made of good old-fashioned meat. Indeed, in a world saturated by low-quality content, the opinions of smart and engaged writers become even more valuable. So we’ve decided to go against the trend, by launching not a journalist powered by AI, but an AI powered by journalists.

Announcing Wrencher-2, a Hackaday chat assistant in your browser

Wrencher-2 is a new paradigm in online chat assistants, eschewing generative algorithms in favour of the collective expertise of the Hackaday team. Ask Wrencher-2 a question, and you won’t get a vague and made-up answer from a computer, instead you’ll get a pithy and on-the-nail answer from a Hackaday staffer. Go on – try it!

NFTs Are The Hope For A New Tomorrow!

April 1, 2021 by Jenny List 54 Comments

Here at Hackaday, we’re always working as hard as we can to bring you the latest and most exciting technologies, and like so many people we’ve become convinced that the possibilities offered by the rise of the Blockchain present unrivaled opportunities for humanity to reinvent itself unfettered by the stifling regulations of a dying system. This is why today we’ve decided to join in with the digital cognoscenti and celebrities embracing Non-Fungible Tokens, or NFTs, as a new promise of non-corporeal digital investment cryptoasset that’s taking the world by storm.

Crypto Non-Fungible Investment Gains!

Imagine for a minute, yourself owning a very expensive car. Skievl, CC BY-SA 4.0.

An NFT is a digital token representing something in the real world, and coupled to a unique ID held in a secure entry in the Blockchain. It’s non-fungible, which means that it’s unique and not interchangeable in the manner of a traditional old-style cryptoasset such as Bitcoin. As it allows a real-world object to be tokenised in digital form it represents a way to own something that provides an irrefutable connection to it as as a digital cryptoasset.

It’s a complex system that’s maybe too difficult to explain fully in a single article, but think of an NFT as a way to invest in a cryptoasset in digital form with its uniqueness guaranteed by Blockchain security, without having the inconvenience of physically owning it. Instead your NFT is safely held on a server on the Internet, and can’t be physically stolen as it would from a bank vault because it has the Blockchain cryptosecurity baked in.

Non Fungible Blockchain Cryptoassets!

You don't own this. Yet. — You don’t own this. Yet.

NFTs have so far found a space in the creative markets, where they have provided a revolutionary opportunity for artists to expand their sales in the digital realm by selling NFTs of their work. A struggling artist can now access buyers all over the world, who can in turn now invest with confidence in creative talent to which they would never otherwise be exposed. It’s a win-win situation in which both cryptoinvestor and artist benefit from The Power of the Blockchain.

Hackaday is excited to offer a once-in-a-lifetime chance to acquire a Blockchain-cryptosecured NFT representing one of our own articles; our first ever NFT is the only officially sanctioned digital copy of a Hackaday article presenting a novel method of handling toilet paper shortages. The original article will continue to exist on Hackaday.com with all rights reserved, but we will not make any other NFTs of it. We may also decide to update the original article to let everyone know you are the lucky owner of the only digital copy of this piece of greatness. That’s right, this NFT will let you prove you own a screenshot!

Having today sold you on the incredible cryptoinvestment opportunity offered by NFTs, we’ll be back on another date with a more sober and in-depth technical examination of the technology behind them. Meanwhile should our brief foray into NFTs garner any interest (and we really hope it does not), we will donate proceeds to the excellent Girls Who Code, a truly solid investment with a tangible bright future.

Thanks [Micah Scott] for some NFT consultancy during the making of this piece.

Hackaday Forced Into Light Mode

April 1, 2021 by Elliot Williams 94 Comments

Hackaday has always been dark mode. Gray10 is less jarring when you’re burning the midnight oil on a project, so we give you a lot of it. Fifteen years ago, it was called “reverse video” or “trog mode“, and we were the freaks. We were doing it wrong. We had the colors “backwards”. Dark mode used to be edgy, outré, but dare we say it, a bit sexy.

Hackaday … QuickBooks. Just sayin’.
They even ripped our highlight yellow!

Flash forward, and everyone has come over to the dark side. Facebook has a dark mode. Google has dark mode. Across the Microsoft empire, from Windows 10 to GitHub, you can live your life in the dark. Heck, even the White House has a dark mode! (They call it high-contrast mode, but they’re not fooling anyone.)

Dark mode here, dark mode there. It’s mainstream. Dark mode has become corporate cool which is nobody’s idea of cool.

We’re not saying that all of the aforementioned institutions are biting the Hackaday style, but, well, they’re all biting our style. Where were they when we were the only website on the whole darn Internet with a sensible background color? Huh? Dark-mode-come-latelys!

But Hackaday doesn’t rest on its laurels. We have our fingers on the pulse on the modern hacker. Where previously you would be up late at night researching Hackaday for juicy nuggets of communal wisdom to help out with your current hack, you’re probably “telecommuting” these days — a euphemism for working on your private projects even while the fiery ball is still in the sky. (Wink, wink, nudge, nudge.) It’s only natural that you’d want a lighter background color to match your new lifestyle. We hear you!

So we present you, Hackaday Light Mode™. Enjoy!

[Editor’s note: For historical accuracy, we had phosphor green headings in the very beginning, in place of the jarring white. If you want to relive those glory days of yore, or just to go back to Hackaday in dark mode, there’s always CSS scripting.]

Accurate Dispensing Of Toilet Paper Will Get Us Through The Crisis

April 1, 2020 by Jenny List 51 Comments

As we enter our second week of official COVID-19-related lockdown where this is being written, it’s evident that there are some resources we will have to conserve to help get us through all this. Instead of just using all of something because we can nip out to the store and buy more, we have to look at what we’ve got and treat it as though it will have to get us through the next three months. It’s not always certain that on our infrequent trips to the supermarket they’ll have stocks of what we want.

This is the very last of the toilet paper in my local supermarket, on the 8th of March.

A particular shortage has been of toilet paper. The news was full of footage showing people fighting for the last twelve-pack, and since early last month there has been none to be had for love nor money. To conserve stocks and save us from the desperate measures of having to cut the Daily Mail into squares and hang them on the wall, a technical solution is required. To this end I’ve created a computerised toilet roll dispenser which carefully controls the quantity of the precious sanitary product, in the hope of curbing its consumption to see us through the crisis.

In the midst of a full lockdown it’s difficult to secure immediate delivery of our usual maker essentials, so rather than send off for the controller boards I might have liked it has been necessary to make do with what I had. In the end I selected an older single board computer I had in a box under my bench. The Sinclair ZX81 has a single-core Z80 processor running at 3.25 MHz, dual-channel memory, a Ferranti GPU, and plenty of expansion possibilities from its black plastic case. I chose it because I could repurpose its thermal printer peripheral as a toilet paper printer, and because it has an easily wiped and hygienic membrane keyboard rather than a conventional one that could harbour germs.

Hardware wise I found I was fairly easily able to adapt a standard roll of Cushelle to the ZX printer, and was soon dispensing sheets with the following BASIC code.

10 REM TOILET PAPER PRINTER
20 FOR T=0 TO 44
30 LPRINT ""
40 NEXT T
50 LPRINT "---------- TEAR HERE -----------"

For now it’s working on the bench, but it will soon be mounted with a small portable TV as a monitor on the wall next to the toilet. Dispensing toilet paper will be as simple as typing RUN and hitting the ZX’s NEW LINE key, before watching as a sheet of toilet paper emerges magically from the printer. It’s the little hacks like this one that will be so useful in getting us through the crisis. After all, this Sinclair always has a square to spare.

Gold Cables Really Do Work The Best

April 1, 2020 by Jenny List 88 Comments

As a writer, I have long harboured a dream that one day an editor will buy me a top-of-the-range audio analyser, and I can set up an audio test lab and write pieces debunking the spurious claims made by audiophiles, HiFi journalists, and the high-end audio industry about the quality of their products. Does that amp really lend an incisive sibilance to the broader soundstage, and can we back that up with some measurable figures rather than purple prose?

An Audio Playground You Didn’t Know You Had

Sadly Hackaday is not an audio magazine, and if Mike bought me an Audio Precision he’d have to satisfy all the other writers’ test equipment desires too, and who knows where that would end! So there will be no Hackaday audio lab — for now. But that doesn’t mean I can’t play around with audio analysis.

Last month we carried a write-up of a Supercon talk from Kate Temkin and Michael Ossmann, in which they reminded us that we have a cracking general purpose DSP playground right under our noses; GNU Radio isn’t just for radio. Once I’d seen the talk my audio analysis horizons were opened up considerably. Maybe that audio analyser wouldn’t be mine, but I could do some of the same job with GNU Radio.

It’s important to stress at this point that anything I can do on my bench will not remotely approach the quality of a professional audio analyser. But even if I can’t measure infinitesimal differences between very high-end audio circuitry, I can still measure enough to tell a good audio product from a bad one.
