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?

FrogFind Grabs The WAP

July 23, 2025 by Tyler August 24 Comments

Yes, the Wireless Application Protocol! What other WAP could there possibly be? This long-dormant cellphone standard is now once again available on the web, thanks to [Sean] over at ActionRetro modifying his FrogFind portal as a translation engine. Now any web site can be shoved through the WAP!

WAP was rolled out in 1999 as HTML for phones without the bandwidth to handle actual HTML. The idea of a “mobile” and a “desktop” site accessed via HTTP hadn’t yet been conceived, you see, so phoning into sites with WAP would produce a super-stripped down, paginated, text-only version of the page. Now FrogFind has a WAP version that does the same thing to any site, just as the HTTP (no S!) FrogFind translates the modern web into pure HTML vintage browsers can read.

Of course you’ll need a phone that can connect to FrogFind with a WAP browser, which for many of us, may be… difficult. This protocol didn’t last much longer than PETS.COM, so access is probably going to be over 2G. With 2G sunset already passed in many areas, that can be a problem for vintage computer enthusiasts who want to use vintage phone hardware. [Sean] does not have an answer — indeed, he’s actively searching for one. His fans have pointed out a few models of handsets that should be able to access WAP via WiFi, but that leaves a lot of retro hardware out in the cold. If you have a good idea for a 2G bridge that can get out to the modern web and not attract the angry attention of the FTC (or its local equivalent), fans of ActionRetro would love to hear it — and so would we!

Vintage phone hacks don’t show up often on Hackaday, and when they do, it’s either much older machines or upgrading to USB-C, not to modern communications protocols. We haven’t seen someone hacking in the WAP since 2008. Given the collective brainpower of the Hackaday commentariat, someone probably has an idea to let everyone dive right into the WAP. Fight it out in the comments, or send us a tip if you have link to a howto.

8-Core ARM Pocket Computer Runs NixOS

July 17, 2025 by Tyler August 9 Comments

What has 8 ARM cores, 8 GB of RAM, fits in a pocket, and runs NixOS? It’s no pi-clone SBC, but [MWLabs]’s smartphone– a OnePlus 6, to be precise.

The video embedded below, and the git link above, are [MWLabs]’s walk-through for loading the mobile version of Nix onto the cell phone, turning it into a tiny-screened Linux computer. He’s using the same flake on the phone as on his desktop, which means he gets all the same applications set up in the same way– talk about convergence. That’s an advantage to Nix in this application, compared to the usual Alpine-based PostMarketOS.

Of course some of the phone-like features of this pocket-computer are lacking: the SIM is detected, and he can text, but 4G is nonfunctional. The rear camera is also not there yet, but given that Mobile-NixOS builds on the work done by well-established PostMarketOS, and PostMarketOS’ testing version can run the camera, it’s only a matter of time before support comes downstream. Depending what you need a tiny Linux device for, the camera functionality may or may not be of particular interest. If you’re like us, the idea of a mobile device running Nix might just intrigue you,

Smartphones can be powerful SBC alternatives, after all. You can even turn them into SBCs. As long as you don’t need a lot of GPIO, like for a server,a phone in hand might be worth two birds in the raspberry bush.

Eulogy For The Satellite Phone

June 23, 2025 by Al Williams 54 Comments

We take it for granted that we almost always have cell service, no matter where you go around town. But there are places — the desert, the forest, or the ocean — where you might not have cell service. In addition, there are certain jobs where you must be able to make a call even if the cell towers are down, for example, after a hurricane. Recently, a combination of technological advancements has made it possible for your ordinary cell phone to connect to a satellite for at least some kind of service. But before that, you needed a satellite phone.

On TV and in movies, these are simple. You pull out your cell phone that has a bulkier-than-usual antenna, and you make a call. But the real-life version is quite different. While some satellite phones were connected to something like a ship, I’m going to consider a satellite phone, for the purpose of this post, to be a handheld device that can make calls.

Adapting An Old Rotary Dial For Digital Applications

June 13, 2025 by John Elliot V 27 Comments

Today in old school nostalgia our tipster [Clint Jay] wrote in to let us know about this rotary dial.

If you’re a young whippersnapper you might never have seen a rotary dial. These things were commonly used on telephones back in the day, and they were notoriously slow to use. The way they work is that they generate a number of pulses corresponding to the number you want to dial in. One pulse for 1, two pulses for 2, and so on, up to nine pulses for 9, then ten pulses for 0.

We see circuits like this here at Hackaday from time to time. In fact, commonly we see them implemented as USB keyboards, such as in Rotary Dial Becomes USB Keyboard and Rotary Dialer Becomes Numeric Keypad.

The DIY 1982 Picture Phone

April 29, 2025 by Al Williams 19 Comments

If you’ve only been around for the Internet age, you may not realize that Hackaday is the successor of electronics magazines. In their heyday, magazines like Popular Electronics, Radio Electronics, and Elementary Electronics brought us projects to build. Hacks, if you will. Just like Hackaday, not all readers are at the same skill level. So you’d see some hat with a blinking light on it, followed by some super-advanced project like a TV typewriter or a computer. Or a picture phone.

In 1982, Radio Electronics, a major magazine of the day, showed plans for building a picture phone. All you needed was a closed-circuit TV camera, a TV, a telephone, and about two shoeboxes crammed full of parts.

Like many picture phones of its day, it was stretching the definition a little. It actually used ham radio-style slow scan TV (SSTV) to send a frame of video about once every eight seconds. That’s not backwards. The frame rate was 0.125 Hz. And while the resulting 128 x 256 image would seem crude today, this was amazing high tech for 1982.

Hacking A Rotary Phone

March 13, 2025 by Al Williams 15 Comments

[Yaymukund] made an interesting observation. Old-style rotary phones were made to last and made for service. Why? Because you didn’t own them, the phone company did. There was no advantage for them for you to need a service call or a new phone. Of course, many of these old phones are still hanging around like the GPO 746 that appears in the post.

What do you do with an old rotary phone? In this case, you make it play a random tune whenever someone picks up the handset. As you might expect, you don’t need much of the original phone to do this. In particular, you need the handset receiver and the switch hook. We’d have liked to read the dial to select a tune, but perhaps that could be in version two.

All the components wire back to a D92732 circuit board. Finding the right wires was a bit finicky, but eventually, a Teensy, a battery pack, and an audio breakout board were in place. The rest is mostly trivial.

[Yaymukund] spent about £300, but over half of that was on tools most Hackaday readers will already have. The phone itself was £65. You can use these phones as a basis for many projects. Even if you want to go mobile.
