TréPhonos Calls Up History In Houston

Posted on by

Houston’s historic third ward, aka “The Tre,” is ripe with history, and some of that history is digitally preserved and accessible through an art installation in the form of repurposed payphones. We love payphones for obvious reasons and seeing them alive and kicking warms our hearts. Packing them with local history checks even more boxes. Twenty-four people collaborated to rebuild the three phones which can be seen in the video after the break, including three visual artists, three ambassadors, and eighteen residents who put their efforts into making the phones relevant not only to the ward but specifically to the …read more

CNC Mill Repairs iPhone 7

Posted on by

Modern smartphones are highly integrated devices, bringing immense computing power into the palm of one’s hand. This portable computing power and connectivity has both changed society in innumerable ways, and also tends to lead to said powerful computers ending up dropped on the ground or into toilets. Repairs are often limited to screen replacement or exchanging broken modules, but it’s possible to go much further.

The phone is an iPhone 7, which a service center reported had issues with the CPU, and the only fix was a full mainboard replacement. [The Kardi Lab] weren’t fussed, however, and got to work. …read more

3D Printed Head Can Unlock Your Phone

Posted on by

[Thomas Brewster] writes for Forbes, but we think he’d be at home with us. He had a 3D printed head made in his own image and then decided to see what phones with facial recognition he could unlock. Turns out the answer is: most of them — at least, those running Android.

The models tested included an iPhone X, an LG, two Samsung phones, and a OnePlus. Ironically, several of the phones warn you when you enroll a face that the method may be less secure than other locking schemes. Conversely, one phone had a faster feature that is known …read more

Manhattan Mystery of Creepy Jingles and Random Noises Solved

Posted on by

Here’s a puzzler for you: If you’re phreaking something that’s not exactly a phone, are you still a phreak?

That question probably never crossed the minds of New Yorkers who were acoustically assaulted on the normally peaceful sidewalks of Manhattan over the summer by creepy sounds emanating from streetside WiFi kiosks. The auditory attacks caused quite a stir locally, leading to wild theories that Russian hackers were behind it all. Luckily, the mystery has been solved, and it turns out to have been part prank, part protest, and part performance art piece.

To understand the exploit, realize that New York …read more

5G Cellphone’s Location Privacy Broken Before It’s Even Implemented

Posted on by

Although hard to believe in the age of cheap IMSI-catchers, “subscriber location privacy” is supposed to be protected by mobile phone protocols. The Authentication and Key Agreement (AKA) protocol provides location privacy for 3G, 4G, and 5G connections, and it’s been broken at a basic enough level that three successive generations of a technology have had some of their secrets laid bare in one fell swoop.

When 3G was developed, long ago now, spoofing cell towers was expensive and difficult enough that the phone’s International Mobile Subscriber Identity (IMSI) was transmitted unencrypted. For 5G, a more secure version based on …read more

Retro Wall Phone Becomes A Doorbell, And So Much More

Posted on by

We have to admit that this retasked retro phone wins on style points alone. The fact that it’s filled with so much functionality is icing on the cake.

The way [SuperKris] describes his build sounds like a classic case of feature creep. Version 1 was to be a simple doorbell, but [SuperKris] would soon learn that one does not simply replace an existing bell with a phone and get results. He did some research and found that the ringer inside the bakelite beauty needs much more voltage than the standard doorbell transformer supplies, so he designed a little H-bridge circuit …read more

Vintage Rotary Phone Turned Virtual Assistant

Posted on by

Like many of us, [Zoltan Toth-Czifra] has completely embraced 21st century living. His home is awash in smart gadgets and dodads, from color changing light bulbs to Internet-connected cameras. But he’s also got a soft spot for the look and feel of vintage hardware, like the rotary phone he keeps kicking around to remind him of the old days. He recently decided to bridge these two worlds by turning the rotary phone into a modern voice controlled assistant.

The first piece of the puzzle was getting the old school phone connected to something a bit more modern, namely a Raspberry …read more

DIY Telepresence Robot Built From Off-The-Shelf Parts

Posted on by

Telepresence hasn’t taken off in a big way just yet; it may take some time for society to adjust to robotic simulacra standing in for humans in face-to-face communications. Regardless, it’s an area of continuous development, and [MakerMan] has weighed in with a tidy DIY build that does the job.

It’s a build that relies on an assemblage of off-the-shelf parts to quickly put together a telepresence robot. Real-time video and audio communications are easily handled by a Huawei smartphone running Skype, set up to automatically answer video calls at all times. The phone is placed onto the robotic chassis …read more

Hello, And Please Don’t Hang Up: The Scourge of Robocalls

Posted on by

Over the last few months, I’ve noticed extra calls coming in from local numbers, and if you live in the US, I suspect maybe you have too. These calls are either just dead air, or recordings that start with “Please don’t hang up.” Out of curiosity, I’ve called back on the number the call claims to be from. Each time, the message is that this number has been disconnected and is no longer in service. This sounds like the plot of a budget horror movie, how am I being called from a disconnected number? Rather than a phantom in the …read more

Smartphone Mod Goes Out On A Limb

Posted on by

The modern smartphone has a variety of ways to interact with its user – the screen, the speakers, and of course, the vibration motor. But what if your phone could interact physically? It might be unnerving, but it could also be useful – and MobiLimb explores exactly this possibility.

Yes, that’s right – it’s a finger for your mobile phone. MobiLimb has five degrees of freedom, and is built using servomotors which allow both accurate movement as well as positional feedback into the device. Additionally, a touch-sensitive potentiometer is fitted, allowing the robofinger to respond to touch inputs.

The brains …read more
