Personalization, Industrial Design, And Hacked Devices

July 26, 2025 by Elliot Williams 28 Comments

[Maya Posch] wrote up an insightful, and maybe a bit controversial, piece on the state of consumer goods design: The Death Of Industrial Design And The Era Of Dull Electronics. Her basic thesis is that the “form follows function” aesthetic has gone too far, and all of the functionally equivalent devices in our life now all look exactly the same. Take the cellphone, for example. They are all slabs of screen, with a tiny bezel if any. They are non-objects, meant to disappear, instead of showcases for cool industrial design.

Of course this is an extreme example, and the comments section went wild on this one. Why? Because we all want the things we build to be beautiful and functional, and that has always been in conflict. So even if you agree with [Maya] on the suppression of designed form in consumer goods, you have to admit that it’s not universal. For instance, none of our houses look alike, even though the purpose is exactly the same. (Ironically, architecture is the source of the form follows function fetish.) Cars are somewhere in between, and maybe the cellphone is the other end of the spectrum from architecture. There is plenty of room for form and function in this world.

But consider the smartphone case – the thing you’ve got around your phone right now. In a world where people have the ultimate homogeneous device in their pocket, one for which slimness is a prime selling point, nearly everyone has added a few millimeters of thickness to theirs, aftermarket, in the form of a decorative case. It’s ironically this horrendous sameness of every cell phone that makes us want to ornament them, even if that means sacrificing on the thickness specs.

Is this the same impetus that gave us the cyberdeck movement? The custom mechanical keyboard? All kinds of sweet hacks on consumer goods? The need to make things your own and personal is pretty much universal, and maybe even a better example of what we want out of nice design: a device that speaks to you directly because it represents your work.

Granted, buying a phone case isn’t necessarily creative in the same way as hacking a phone is, but it at least lets you exercise a bit of your own design impulse. And it frees the designers from having to make a super-personal choice like this for you. How about a “nothing” design that affords easy personalized ornamentation? Has the slab smartphone solved the form-versus-function fight after all?

Trickle Down: When Doing Something Silly Actually Makes Sense

July 12, 2025 by Elliot Williams 10 Comments

One of the tropes of the space race back in the 1960s, which helped justify the spending for the part of the public who thought it wasn’t worth it, was that the technology developed for use in space would help us out here back on earth. The same goes for the astronomical expenses in Formula 1, or even on more pedestrian tech like racing bikes or cinematography cameras. The idea is that the boundaries pushed out in the most extreme situations could nonetheless teach us something applicable to everyday life.

This week, we saw another update from the Minuteman project, which is by itself entirely ridiculous – a 3D printer that aims to print a 3D Benchy in a minute or less. Of course, the Minuteman isn’t alone in this absurd goal: there’s an entire 3D printer enthusiast community that is pushing the speed boundaries of this particular benchmark print, and times below five minutes are competitive these days, although with admittedly varying quality. (For reference, on my printer, a decent-looking Benchy takes about half an hour, but I’m after high quality rather than high speed.)

One could totally be forgiven for scoffing at the Speed Benchy goal in general, the Minuteman, or even The 100, another machine that trades off print volume for extreme speed. But there is definitely trickle-down for the normal printers among us. After all, pressure advance used to be an exotic feature that only people who were using high-end homemade rigs used to care about, and now it’s gone mainstream. Who knows if the Minuteman’s variable temperature or rate smoothing, or the rigid and damped frames of The 100, or its successor The 250, will make normal printers better.

So here’s to the oddball machines, that push boundaries in possibly ridiculous directions, but then share their learnings with those of us who only need to print kinda-fast, but who like to print other things than little plastic boats that don’t even really float. At least in the open-source hardware community, trickle-down is very real.

Last Chance: 2025 Hackaday Supercon Still Wants You!

July 3, 2025 by Elliot Williams 2 Comments

Good news, procrastinators! Today was going to be the last day to throw your hat in the ring for a slot to talk at Supercon in November, but we’re extending the deadline one more week, until July 10th. We have an almost full schedule, but we’re still missing your talk.

So if the thought of having missed the deadline fills you with regret, here’s your second chance. We have spots for both 40-minute and 20-minute talks still open. We love to have a mix of newcomers as well as longtime Hackaday friends, so don’t be shy.

Supercon is a super fun time, and the crowd is full of energy and excitement for projects of all kinds. There is no better audience to present your feats of hardware derring-do, stories of reverse engineering, or other plans for world domination. Where else will you find such a density of like-minded hackers?

Don’t delay, get your talk proposal in today.

Limitations, Creativity, And Challenges

June 28, 2025 by Elliot Williams 6 Comments

This week, we announced the winners for the previous Pet Hacks contest and rang in our new contest: The One Hertz Challenge. So that’s got me in a contesty mood, and I thought I’d share a little bit of soap-box philosophizing and inside baseball all at once.

The trick to creating a good contest theme, at least for the creative Hackaday crowd, is putting on the right limitation. Maybe you have to fit the circuit within a square-inch, power it only with a coin cell, or use the antiquated and nearly useless 555 timer IC. (Yes, that was a joke!)

There are two basic reactions when you try to constrain a hacker. Some instantly try to break out of the constraint, and their minds starts to fly in all of the directions that lead out of the box, and oftentimes, something cool comes out of it. The other type accepts the constraint and dives in deep to work within it, meditating deeply on all the possibilities that lie within the 555.

Of course, we try to accommodate both modes, and the jury is still out as to which ends up better in the end. For the Coin Cell challenge, for instance, we had a coin-cell-powered spot welder and car jumpstarter, but we also had some cool circuits that would run nearly forever on a single battery; working against and with the constraints.

Which type of hacker are you? (And while we’re still in the mood, what contest themes would you like to see for 2026?)

Announcing The 2025 Hackaday One Hertz Challenge

June 26, 2025 by Elliot Williams 56 Comments

It’s about time! Or maybe it’s about time’s reciprocal: frequency. Whichever way you see it, Hackaday is pleased to announce, just this very second, the 2025 One Hertz Challenge over on Hackaday.io. If you’ve got a device that does something once per second, we’ve got the contest for you. And don’t delay, because the top three winners will each receive a $150 gift certificate from this contest’s sponsor: DigiKey.

What will you do once per second? And how will you do it? Therein lies the contest! We brainstormed up a few honorable mention categories to get your creative juices flowing.

Timelords: How precisely can you get that heartbeat? This category is for those who prefer to see a lot of zeroes after the decimal point.
Ridiculous: This category is for the least likely thing to do once per second. Accuracy is great, but absurdity is king here. Have Rube Goldberg dreams? Now you get to live them out.
Clockwork: It’s hard to mention time without thinking of timepieces. This category is for the clockmakers among you. If your clock ticks at a rate of one hertz, and you’re willing to show us the mechanism, you’re in.
Could Have Used a 555: We knew you were going to say it anyway, so we made it an honorable mention category. If your One Hertz project gets its timing from the venerable triple-five, it belongs here.

We love contests with silly constraints, because you all tend to rise to the challenge. At the same time, the door is wide open to your creativity. To enter, all you have to do is document your project over on Hackaday.io and pull down the “Contests” tab to One Hertz to enter. New projects are awesome, but if you’ve got an oldie-but-goodie, you can enter it as well. (Heck, maybe use this contest as your inspiration to spruce it up a bit?)

Time waits for no one, and you have until August 19th at 9:00 AM Pacific time to get your entry in. We can’t wait to see what you come up with.

Measurement Is Science

June 21, 2025 by Elliot Williams 22 Comments

I was watching Ben Krasnow making iron nitride permanent magnets and was struck by the fact that about half of the video was about making a magnetometer – a device for measuring and characterizing the magnet that he’d just made. This is really the difference between doing science and just messing around: if you want to test or improve on a procedure, you have to be able to measure how well it works.

When he puts his home-made magnet into the device, Ben finds out that he’s made a basically mediocre magnet, compared with samples out of his amply stocked magnet drawer. But that’s a great first data point, and more importantly, the magnetometer build gives him a way of gauging future improvements.

Of course there’s a time and a place for “good enough is good enough”, and you can easily spend more time building the measurement apparatus for a particular project than simply running the experiment, but that’s not science. Have you ever gone down the measurement rabbit hole, spending more time validating or characterizing the effect than you do on producing it in the first place?
