What does post-apocalyptic technology look like? Well, that kind of depends on the apocalypse. Regardless of the cause, we’ll need to be clever and resourceful and re-learn ancient crafts like weaving and pottery-making. After all, the only real apocalyptic constants are the needs of the survivors. Humans need clothing and other textiles. Fortunately, weaving doesn’t require electricity—just simple mechanics, patience, and craftsmanship.
If it turns out the apocalypse is scheduled for tomorrow, we’ll have piles and piles of e-waste as fodder for new-old looms. This adorable loom is a mashup of old and new technologies that [Kati Hyyppä] built at …read more
Picture it: Halloween, 2018. You want to go to a party or take the kids out trick-or-treating, but remember what happened last year when you weren’t there to answer the door? A pack of wild children blew their allowances on 48 rolls of the cheapest toilet paper ever printed, and it took you four full hours to get all the sodden, dew-laden wads out of your rose bushes.
Halloween is a time to fear things like hobgoblins and the possibility of The Purge becoming a thing, not sugar-fueled children who are upset that you left out a bowl of Sixlets, …read more
It’s that time of year again, at least in the northern hemisphere. Everything is alive and growing, especially that narrow-leafed non-commodity that so many of us farm without tangible reward. [sonofdodie] has a particularly hard row to hoe—his backyard is one big, 30° slope of knee-ruining agony. After 30 years of trudging up and down the hill, his body was telling him to find a better way. But no lawn service would touch it, so he waited for divine inspiration.
And lo, the answer came to [sonofdodie] in a trio of string trimmers. These Whirling Dervishes of grass grazing are …read more
Have you ever noticed how “one size fits all” often means “one size poorly fits all”? This became especially clear to me when I started using a compression sleeve on my arm. Like any hacker, this seemed like something I could fix, so I gave it a shot. Boy, did I learn a lot in the process.
A little over a year ago, I started dropping things. If I was holding something in my left hand, chances were good that it would suddenly be on the ground. This phenomenon was soon accompanied by pain and numbness, particularly after banging on …read more
In our fast-paced modern world, it’s no wonder that so many suffer from anxiety and panic attacks. There are several time-worn techniques for dealing with the symptoms of these attacks. But as anyone who’s ever suffered such an attack can tell you, it can be difficult to sense one coming on until it’s too late. By then, rational thinking has been supplanted by intrusive thoughts. For this year’s Hackaday Prize, [Austin Marandos] is doing his part by using technology to help us check ourselves before we wreck ourselves with worry.
Similar smartwatches exist to detect oncoming attacks, but they don’t …read more
They say an ounce of prevention is worth a pound of cure. In this case, 38,000 gallons of seawater is worth an un-quantifiable amount of knowledge about hurricanes. At the University of Miami’s Rosenstiel School of Marine and Atmospheric Science, [Brian Haus] and his colleagues study hurricanes using a simulator–an enclosed glass tank about the size of a lap-swimming pool. With the flip of a switch, a 1700 hp fan can create winds up to 200 miles per hour—stronger than a baseline category 5 hurricane.
Although there’s currently no cure for hurricanes, understanding how they work goes a long way …read more
As an electrical engineering student, [Brandon Rice] had the full suite of electronics tools you’d expect. Cramming them all into a dorm room was doable — but cramped — a labour to square everything away from his desk’s top when he had to work on something else. To make it easier on himself, he built himself a portable electronics workstation inside the dimensions of a briefcase.
Built from scratch, the workstation includes a list of features that should have you salivating by the end. Instead of messing with a bunch of cables, on-board power is supplied by a dismantled 24V, …read more
If you’ve ever disturbed your partner by getting up during the night and flicking on the bathroom light — or tripping over something and startling them awake completely in the ensuing catastrophe — [Kristjan Berce]’s idea to install motion-activated ground-effect lighting on his girlfriend’s bed might hold your attention.
[Berce] is using an Arduino Nano for the project’s brain, a PIR sensor from Adafruit, and an L7805 voltage regulator to handle load spikes. He doesn’t specify the type of LED strip he’s using, but Neopixels might be a safe bet here. Soldering issues over with, he …read more
If you’ve spent any serious time in libraries, you’ve probably noticed that they attract people who want or need to be alone without being isolated. In this space, a kind of silent community is formed. This phenomenon was the inspiration [MoonAnchor23] needed to build a network of connected house plants for a course on physical interaction and realization. But you won’t find these plants unleashing their dry wit on twitter. They only talk to each other and to nearby humans.
No living plants were harmed during this project—the leaves likely wouldn’t let much light through, anyway. The plants are each …read more
