Make the Time to Fix Your Time Debt

Posted on by

You’re too busy to read more than this intro paragraph. We all are. Your interest might get piqued enough to skim, but you can’t read the full thing. Our lives all resemble the Mad Hatter, constantly late for our next thing, never enjoying the current thing. You feel simultaneously super productive and yet never productive enough to be satisfied. You yearn for a Jarvis that can automate the mundane aspects of your projects, and yet the prospect of building a Jarvis causes anxiety about not having enough time for yet another project. You see another YouTuber showing off not only …read more

Sudo Find Me a Parking Space; Machine Learning Ends Circling the Block

Posted on by

If you live in a bustling city and have anyone over who drives, it can be difficult for them to find parking. Maybe you have an assigned space, but they’re resigned to circling the block with an eagle eye. With those friends in  mind, [Adam Geitgey] wrote a Python script that takes the video feed from a web cam and analyzes it frame by frame to figure out when a street parking space opens up. When the glorious moment arrives, he gets a text message via Twilio with a picture of the void.

It sounds complicated, but much of the …read more

Hack Your File Hierarchy with Johnny Decimal System (Dewey’s Older Brother)

Posted on by

Most of us have our fair share of digital debris. After all, with drives measured in one-million-million byte increments it’s tempting to never delete anything. The downside is you may never be able to find anything either. [Johnny Noble] must have gotten pretty fed up with clutter when he decided to formalize and publish his own numeric system for organizing everything he comes in contact with. It’s called Johnny Decimal and it’s actually pretty simple!

This is of course a play on words for the Dewey Decimal system. Dewey is one of a variety of information organization systems used by …read more

Glasses For The Hearing Impaired?

Posted on by

If you don’t have hearing loss, it is easy to forget just how much you depend on your ears. Hearing aids are great if you can afford them, but they aren’t like glasses where they immediately improve your sense in almost every way. In addition to having to get used to a hearing aid you’ll often find increased noise and even feedback. If you’ve been to a theater lately, you may have noticed a closed caption display system somewhere nearby that you can sit within visual range of should you be hard of hearing. That limits your seat choices though, …read more

The E-Waste Apocalypse Looms

Posted on by

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

Mario Candy Machine Gamifies Halloween

Posted on by

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

Lawn From Hell Saved by Mower From Heaven

Posted on by

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

Stretching My Skills: How (and Why) I Made My Own Compression Sleeves

Posted on by

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

Smartwatch Fights Anxiety with Action

Posted on by

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

Hurricane Simulator Buoys Research

Posted on by

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
