Category Archives: Cellphone Hacks
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
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
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
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
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.

If you haven’t been paying attention, live streaming has become a big business. Streamers are getting out of their basements and moving around among us. While IRL streams may not be our cup of tea, the technology behind creating a solid high upstream bandwidth wireless internet connection is. Sure you can stream with a phone, the top streamers want something a bit more reliable. Enter [Gunrun], who has designed a backpack just for mobile streaming.
The backpack starts with a Sony AS300 Camera. [Gunrun] likes this particular camera for its exceptional audio capabilities. Network connections are handled with no less …read more
Whether or not you personally like the concept of the AirPod Bluetooth headphones is irrelevant, as an Apple product one thing is certain: all the cool kids want them. That also means that plenty of overseas manufacturers are pumping out janky clones for a fraction of the price for those who are more about the Apple look than the Apple price tag. Are they any good? No, of course not. But that doesn’t mean you can’t do something interesting with them.
[Igor Kromin] took apart a pair of fake AirPods and was predictably underwhelmed. So much so that he didn’t …read more
As is always the case with a significant hacker camp, we’ve been awaiting the official badge announcement for the upcoming Electromagnetic Field 2018 hacker camp with huge interest. These badges, for readers who may have been on Mars for the past few years, are part of a lively scene of wearable electronics at hacker conferences and camps, and can usually be expected to sport a fully-fledged computer in their own right along with other special functionality.
The announcement of the 2018 badge, dubbed the TiLDA Mk4, does not disappoint. We’d been told that there would be an on-site GSM network …read more
With mobile phones now ubiquitous for the masses in much of the world for over two decades, something a lot of readers will be familiar with is a drawer full of their past devices. Alongside the older smartphone you’ll have a couple of feature phones, and probably at the bottom a Nokia candybar or a Motorola flip phone. There have been various attempts over the years to make use of the computing power the more recent ones contain through using their smartphone operating systems, but the older devices remain relatively useless.
[Vishwasnavada] has a neat plan though, using an ancient …read more
You probably don’t think much about charging your phone. Just find an outlet, plug it in, and wait a while. Can’t find a cable or wall wart? A rainbow of cheap, candy-colored options awaits you down at the brightly-lit corner drugstore.
This scenario couldn’t be further from reality in third world countries like Papua New Guinea, where people living in remote jungles have cell phone coverage, but have to charge their phones by hooking them up directly to cheap solar panels and old car batteries.
[Marius Taciuc] wants to change all of that. At the suggestion of his friend [Brian], …read more
