A Conference Badge Breathes Life Into A Rotary Phone

We have covered the astonishing diversity of conference badges to a great extent over the years, and we are always pleased and surprised at the creativity and ingenuity that goes into their creation. But the saddest thing about so many badges is that after the event they go into the …read more

Warshipping: A Free Raspberry Pi In The Mail Is Not Always A Welcome Gift

Leading edge computer security is veiled in secrecy — a world where novel attacks are sprung on those who do not yet know what they need to protect against. Once certain tactics have played out within cool kids’ circles, they are introduced to the rest of the world. An IBM …read more

5G Power Usage Is Making Phones Overheat In Warm Weather

As reported by ExtremeTech, the brand new 5G network is running into a major snag with mobile devices as Qualcomm 5G modems literally cannot handle the heat. After just a few minutes of use they’re going into thermal shutdown and falling back to measly 4G data rates. Reports by both …read more

Add Scroll Wheels and Buttons to Smartphones with 3D-Printed Widgets Read by Accelerometer

The first LED digital wristwatches hit the market in the 1970s. They required a button push to turn the display on, prompting one comedian to quip that giving one to a one-armed man would be in poor taste. While the UIs of watches and other wearables have improved since then, …read more

A Very Different ‘Hot Or Not’ Application For Your Phone

Radioactivity stirs up a lot of anxiety, partially because ionizing radiation is undetectable by any of the senses we were born with. Anytime radiation makes the news, there is a surge of people worried about their exposure levels and a lack of quick and accurate answers. Doctors are flooded with calls, detection devices become scarce, and fraudsters swoop in to make a quick buck. Recognizing the need for a better way, researchers are devising methods to measure cumulative exposure experienced by commodity surface mount resistors.

Cumulative exposure is typically tracked by wearing a dosimeter a.k.a. “radiation badge”. It is standard …read more

Finding the Goldilocks Cell Module

If adding a cell modem is dealing with a drama queen of a hardware component, then choosing from among the many types of modules available turns the designer into an electronics Goldilocks. There are endless options for packaging and features all designed to make your life easier (or not!) so you-the-designer needs to have a clear understanding of the forces at work to come to a reasonable decision. How else will Widget D’lux® finally ship? You are still working on Widget D’lux®, aren’t you?

OK, quick recap from last time. Cell modems can be used to add that great feature …read more

Creating a 3G Raspberry Pi Smartphone

It’s hard to believe, but the Raspberry Pi has now been around long enough that some of the earliest Pi projects could nearly be considered bonafide vintage hacks at this point. A perfect example are some of the DIY Raspberry Pi smartphone projects that sprung up a few years back. Few of them were terribly practical to begin with, but even if you ignore the performance issues and bulkiness, the bigger problem is they relied on software and cellular hardware that simply isn’t going to cut it today.

Which was exactly the problem [Dylan Radcliffe] ran into when he wanted …read more

EMMC Data Recovery From A Bricked Phone

We’ve probably all got at least one old cell phone lurking somewhere around our bench. In most cases they’ll still work, but their  batteries may be exhausted and their OS could be an ancient version. But sometimes there will be a phone that just died. One minute the flagship model, the next a useless slab of plastic and glass with the added annoyance of those priceless photos of Aunty May’s 80th forever locked in its memory.

[Andras Kabai] had just such a device land on his desk, a high-end Sony whose screen had gone blank. Others had tried, he was …read more

Hacker Pops Top On NFC Vending Machines

Vending machines used to be a pretty simple affair: you put some coins in, and food or drink that in all likelihood isn’t fit for human consumption comes out. But like everything else today, they are becoming increasingly complex Internet connected devices. Forget fishing around for pocket change; the Coke machine at the mall more often than not has a credit card terminal and a 30 inch touch screen display to better facilitate dispensing cans of chilled sugar water. Of course, increased complexity almost always goes hand in hand with increased vulnerability.

So when [Matteo Pisani] recently came across a …read more

ESP8266 Powered Tank With Voice Control

The high availability of (relatively) low cost modular components has made building hardware easier than ever. Depending on what you want to do, the hardware side of a project might be the hacker equivalent of building with LEGO. In fact, we wouldn’t be surprised if it literally involved building with LEGO. In any event, easy and quick hardware builds leave more time for developing creative software to run the show. The end result is that we’re starting to see very complex systems broken down into easy-to-replicate DIY builds that would have been nearly impossible just a few years ago.
