Most spy movies (at least the ones worth their salt) will include a few scenes that depict nerds in a van listening in on conversations remotely and causing the victims phones to do things like turn themselves or their cameras on. We have been made to believe that it takes an entire van of equipment and one or two MIT level hackers to pull this off. Turns out all it takes is about $2300, some know how, and an unsuspecting target with a set of microphone-equipped headphones attached to their phone.
The French Government’s information security research group ANSSI has been investigating this and published a paper with their findings. Unfortunately that paper is behind a paywall. Wired has a pretty good summation of the findings, which use a transmitter to induce a current in the headphone wires. This in itself isn’t surprising. But they’re able to do it with such accuracy that it can both trigger, and successfully interact with the hands-free features provided by Siri and Google Now.
We think this is a really cool proof-of-concept. It’s mentioned that an attacker could potentially use this to make calls or do other things that cost the victim money. We think it’s more likely to be implemented by resourceful young engineers as a practical joke. Rick Rolling is a poplar go-to. But if you can make the phone “hear” audio, you should also be able to make someone wearing headphones hear ghosts. This has a lot of potential. The first one to make this happen really needs to let us know about it.
For one reason or another, someone decided smartphones should have personalities. iPhones have Siri, Windows phones have Cortana, but these are just pieces of software, and not a physical representation of a personality. This may soon change with Sharp, with help from famous Japanese roboticist [Tomotaka Takahashi], releasing RoBoHoN, the first robotic smartphone.
RoBoHoN is by any measure a miniature humanoid robot; it can walk on two legs, it can wave its arms, and it can fit into excessively large pockets. This robot is also a phone, and inside its cold soulless chassis is a 2.0″ LCD, camera, pico projector to display movies and pictures on flat surfaces, and the electronics to turn this into a modern, mid-range smartphone.
In the video for RoBoHoN, this friendly little phone can do everything from hail a cab, add stuff to a shopping list, and be the life of the party. According to Akihabara News, Sharp should be releasing this tiny robot sometime in early 2016 but no word yet on price.

If you’ve spent much time tinkering with electronics, you’ve probably heard of [Seeedstudio] from their development boards, tools, and their PCB fabrication service. Their latest Kickstarter venture is the RePhone, an open source and modular cell phone that will allow hackers to put together a phone by blending GSM modules, batteries, screens, and other stock units, including an Arduino-based processing core, GPS, NFC, and other building blocks.
The funding campaign has already exceeded its goal and delivery is scheduled for next year with a basic kit weighing in at a projected $59, according to [Seeed]. Presumably, the core phone module will have regulatory acceptance, but the other ancillary modules won’t require as rigorous testing and certification.
What would you do with an inexpensive, embeddable cell phone? The modules are tiny, so you could implant them in lots of places. Some of [Seeed’s] more interesting ideas include building a phone into a walking stick, a dog collar, or a kite (although we were thinking quadcopters).
Of course, we’ve seen GSM and cell phone shields for Arduino before. Difficult to imagine sticking those in a dog collar, though, unless you have a fairly large dog. If you are a fan of 1960’s TV, it is easy to imagine a better shoe phone or a working Star Trek communicator.

We have seen a few projects that convert a rotary dial for use with modern technology, but this one adds a new twist to the mix: it uses Bluetooth 4.0. [Silent] used a Nordic Semiconductor NRF51 DK development board for the project, which was built from the Nordic SDK source code for creating an HID (Human Interface Device). After what he claims was an hour or so of hacking, he was able to get this Arduino-compatible SoC dev board to detect the pulses from the rotary dial, then pass the appropriate number to a connected device as a key press. This means that his design should work with any device that has Bluetooth 4.0 support. It is powered from a big dry cell because, to quote [Silent], “small coin batteries are not hipster enough”.
It’s a simple project, and we have seen rotary cell phones before, but this still is ripe for expansion. You could either use a smaller, cheaper version of the Nordic chip at the center of this hack, as most of the dev board features aren’t used. Or you could do some more hacking, add support for the Bluetooth HSP headset profile, then wire it up to a vintage phone for the most hipster Bluetooth headset ever. We can’t wait until we see a hipster sitting in a coffee shop banging away on a typewriter and answering this. Get to it, people!

We all remember the good ol’ days when smartphones were just getting started. Realizing that we could take a fully functional computer and shove it into something the size of a phone was pretty revolutionary. Some of the early phones like the original Motorola Droid had some features that just aren’t very common today, and [liviu] set out to fix this situation by adding a sliding QWERTY keyboard to his modern smartphone.
The build started with a Samsung Galaxy Note 4 and two cases: one for the phone and one for the keyboard. [liviu] found a small phone-sized bluetooth keyboard and removed all of the unnecessary bits before shoehorning it into the case. He then built the sliding mechanism from parts out of a PC power supply and two old flip phones and then was able to piece the two halves together. Using the two flip phone hinges gave this case the additional feature of being able to flip up after sliding out. The result is a modern smartphone with a fantastic and classic smartphone twist that looks very useful.
We’ve featured projects that give new life to old smartphones, but this might be the first to give old life to a new smartphone. We wouldn’t mind seeing more flagship phones that come with these features, but [liviu] has done a great job of making up for the manufacturers’ shortcomings!

There’s a slew of apps out there for tracking your bike rides. If you want to monitor your ride while using the app, you’ll need it securely affixed to your bike. That’s where [Gord]’s No Dropped Calls build comes in. This aluminium mount was hand milled and anodized, which gives it a professional finish.
The mount consists of 3 parts which were machined out of stock 6061 aluminium. The plans were dreamt up in [Gord]’s head, and not drawn out, but the build log gives a good summary of the process. By milling away all of the unnecessary material, the weight of the mount was minimized.
Once the aluminium parts were finished, they were anodized. Anodization is a process that accelerates the oxidization of aluminum, creating a protective layer of aluminium oxide. [Greg] does this with a bucket of sulphuric acid and a power supply. Once the anodization is complete, the part is dyed for coloring. If you’re interested, [Gord] has a detailed writeup on home anodization.
The final product looks great, puts the phone within reach while biking, and prevents phone damage due to “dropped calls.”
As a society we are moving away from land line phones while mobile devices are becoming more and more prevalent. It is not uncommon for people to only have a cell phone and completely skip out on the corded home phone. While this move may be for convenience, there is one difference between the two phone types that didn’t ring well with [Stavros]. He’s an angry phone talker and misses the ability to slam down a phone handset. Now [Stavros] could just have a corded home phone but he wanted a mobile option for handset slams so he came up with a project called iRotary. It’s an old school rotary phone converted to be battery powered and uses cell phone networks for making calls.
At the heart of the project is an Arduino. The Arduino is a great choice as it can easily decode the phone’s rotary dial pulses. The Arduino code takes all of the individual dialed numbers and combines them into a phone number. The sketch is set up so that after the 10th digit is read, the phone call is placed using an off the shelf GSM shield and associated library.
Since a battery would be necessary to make this phone mobile, one was installed inside the case along with a charging circuit. [Stavros] hasn’t done any long-term endurance studies but he has had the phone on for several hours at a time without any problems. So, now he can rest easy knowing that an angry hang-ups are never out of his reach, regardless of where he may be. And since he’s a nice guy, he’s made the source code available for anyone wanting to make something similar.
