Control Your Web Browser Like It’s 1969

Imagine for a moment that you’ve been tasked with developing a device for interfacing with a global network of interconnected devices. Would you purposely design a spring-loaded dial that can do nothing but switch a single set of contacts on and off from 1 to 10 times? What kind of …read more

Bluetoothing Beautiful Phones

You’ve seen a landline phone converted into a Bluetooth headset. There’s nothing new there. It’s great for confusing kids when asking them to dial a rotary phone, but that’s about it. It’s the same phone, built by Ma Bell for fifty years, converted with a little Bluetooth breakout board.

You’ve …read more

Telephone Plays The Songs Of Its People

Music, food, and coding style have one thing in common: we all have our own preferences. On the other hand, there are arguably more people on this planet than there are varieties in any one of those categories, so we rarely fail to find like-minded folks sharing at least some …read more

CNC Mill Repairs iPhone 7

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

[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

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

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

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

Unphotogenic Lighting As A Feature

Have you ever taken a picture indoors and had unsightly black bars interrupt your otherwise gorgeous photo? They are caused by lighting which flickers in and out in its normal operation. Some people can sense it easier than others without a camera. The inconsistent light goes out so briefly that we usually cannot perceive it but run-of-the-mill camera phones scan rows of pixels in sequence, and if there are no photons to detect while some rows are scanned, those black bars are the result. Annoying, right?

What if someone dressed that bug of light up as a feature? Instead of …read more

The Bad Old Days of Telephone Answering Machines

Telephone answering machines were almost a fad. They were hindered for years by not being allowed to connect to the phone lines. Then a mix of cell phones and the phone company offering voicemail made the machines all but obsolete. Unless you are really young, you probably had one at some point though. Some had digital outgoing messages and a tape to record. Some had two tapes. But did you ever have one that didn’t connect to the phone line at all? Remember, there was a time when they couldn’t. My family had one of these growing up and after …read more
