Cell phones have become part of our daily life. No longer just for making phone calls, cell phones are like tiny computers we carry around at all times. Just like any other computer, people are hacking cell phones like crazy. This could be anything from jailbreaking your iphone to rooting your android, but it isn't limited to that! We've seen android hacks ranging from tutorials for writing android apps to using your android phone to crack wifi passwords. Iphone hacks are pretty common too, like using an iphone to make vine timelapse movies.

Of course, there are also hacks out there involving cell phone accessories, like how to tripod mount anything, or how to turn your bluetooth headphones into a car auxiliary jack. How about using your cellphone to control a robot or having your cell phone tell you when you've caught a fish? We just can't get enough cellphone hacks!

Pwning Timberman with Electronically Simulated Touchscreen Presses

arduino-plays-timerman

What do you do if you suck at a smartphone game? Buy some in-game upgrades to pretend like you’re good? Screw that! [Valentin] did what any self-respecting hacker would: developed an automated system to play for him.

Granted, when you see the demo video embedded below you’ll realize there isn’t much strategy involved in this game. But that setup to simulate the touchscreen presses is pretty neat. We’re used to seeing mechanical touchscreen hacks but this one is electronic, using a couple of pads of copper foil tape and some relays to make it happen. Here’s the one caveat: you still need to be touching something with your hand. This just uses the relays to switch the connection between the pads and your body.

We’ve looked around for this before. Does anyone have a cheap, simple, and effective hack to fully automate presses on a modern touchscreen? Can we use a potato or something? Tell us below, but send it in to the tips line too!

Embedding Wireless Charging into Your Laptop

Wireless charger in chromebook

Looking for a project to do [Jason Clark] thought it might be fun to integrate a spare wireless Qi charger into his HP Chromebook 14.

He started by cracking open the Qi charger — it’s held together by adhesive and four phillips screws hiding under the feet pads — all in all, not that difficult to do. Once the plastic is off, the circuit and coil are actually quite small making it an ideal choice for hacking into various things. We’ve seen them stuffed into Nook’s, a heart, salvaged for a phone hack…

Anyway, the next step was opening up the Chromebook. The Qi charger requires 5V at 2A to work, which luckily, is the USB 3.0 spec — of which he has two ports in the Chromebook. He identified the 5V supply on the board and soldered in the wires directly —  Let there be power!

While the coil and board are fairly small, there’s not that much space underneath the Chromebook’s skin, so [Jason] lengthened the coil wires and located it separately, just below the keyboard. He closed everything up, crossed his fingers and turned the power on. Success!

It’d be cool to do something similar with an RFID reader — then you could have your laptop locked unless you have your RFID ring with you!

The Rotary Cell Phone

It’s happened. It’s finally happened. In a move that has hipsters donning their good flannel and breaking out that case of Genesee they were saving for a special occasion, the rotary cell phone is now a reality.

[Jaromir] created this astonishingly retro future device as an entry for the NXP LPC810 challenge, a contest to do the most with an ARM Cortex M0+ microcontroller in an 8-pin package. Having only six I/O pins for controlling a GSM module, display a few buttons, and the fancy rotary dial meant [Jaromir] needed to expand his I/O some way. He chose a shift register to handle the buttons and display in a somewhat impressive demonstration of using a shift register as both an input and output expander at the same time.

From the videos [Jaromir] uploaded, the rotary cell phone isn’t ready for Think Geek to do a production run quite yet. He needs to enter the PIN for the SIM card, AT commands for the GSM module, and is, of course, a horrible method of user input for the younglings who have only seen rotary phones in old movies. That being said, it’s a rotary cell phone running on an 8-pin microcontroller. What more do you want?

Videos of this awesome this truly awesome phone in action below. If you’d like to build your own – and why wouldn’t you – all the files are available on [Jaromir]‘s git

Call A Cell Phone, Find A Tent

relay Finding your tent at a music festival is a tricky endeavor – not only are there miles and miles of tents exactly like yours, you most likely have a few beers or other substances in you that affect your sense of space and/or time.  [James] came up with a great solution to finding your tent by illuminating it with Christmas lights and a cell phone.

The basic idea of [James]‘ build is having Christmas light flicker whenever he calls a phone. One feature in nearly every phone that can be exploited to accomplish this task is the backlight turning on when a call is received. Add a phototransistor, a little bit of circuitry, and some Christmas lights, and you have a fully functioning tent finder.

[James]‘ circuit is a simple relay driving the Christmas lights, triggered by a phone right on top of the phototransistor. It’s a simple circuit that can be built on a piece of veroboard, and with a few pieces of plastic forming the enclosure, provides a reasonably bulletproof device that will survive the rigors of a music festival. As a bonus, there’s no need to modify the phone to trigger a remote circuit. Video of the device in action below.

Hacking a MagSafe Connector for your iPhone

maglock

The MagSafe power connector for Apple MacBooks is probably one of the handiest features they developed — we’re not too sure why it hasn’t been integrated onto iPhones yet. [Tony Hoang] isn’t sure either, but that didn’t stop him making his very own!

Due to the size of the MagSafe adapter, it’s simply not possible to integrate it directly into an iPhone, so [Tony] took his trusty Otter-box case and modified it instead. He’s using a Qi wireless charging receiver on the inside of the case, because it has a very slim ribbon cable to the USB. Modifying that he was able to solder on the MagSafe adapter directly to the ribbon cable. In order for it to fit nicely through the case, he 3D printed an adapter bracket for it to stay nice and secure.

From there it was just a matter of soldering the MagSafe power cable onto a 5V USB power brick, and boom-bada-bing, he’s got a MagSafe compatible iPhone. Previously he’s done this mod to a Samsung Note II, and plenty of other people have added it to laptops and ultrabooks!

Phoenard: Arduino Phone as Small as An Arduino Mega

 

Hanging out at one side of the Atmel booth at Maker Faire was [Pamungkas Sumasta] who was showing off his Arduino cellphone called Phoenard. We really like the form-factor but its hackability is where it really shines. [Sumasta] showed off the menu system which is quite snappy and makes it simple for you to add your own applications. Software isn’t the only thing you can customize, as there’s a connector at the bottom of the phone. He showed off a breadboard attachment which was hosting LEDs of various colors. Their intensity can be altered using a simple slider app on the touchscreen. But there’s more power if want it. Also on exhibit was a self-balancing robot body which has a connector at the top for the phone.

[Sumasta] won the Atmel Hero contest and we assume that’s how he made it all the way to San Francisco from The Netherlands for Maker Faire. You can learn a few more technical details about Phoenard on the Facebook page.

Magsafe On An Android, Cats And Dogs Living Together

Mag

We’re thinking most Hackaday readers have at one time or another been tasked with replacing the power connector in a laptop. Anyone who has done so can easily see the genius behind the Apple Magsafe connector. Since the second gen iPhone, there have been rumors Apple will release a cellphone with the Magsafe connector, a great idea, seeing as how cell phones are thrown around even more than laptops. [Tony] got tired of waiting, and had an Android device anyway, so he decided to retrofit a Magsafe power adapter to his Note II.

In the interest of excess, [Tony] is using the absurdly large ZeroLemon 9300mAh battery and case for his device, giving him a lot of room for this hardware mod. A tiny 3D printed adapter fits around a slightly modified Magsafe connector, and with a little bit of super glue and solder, the connector is wired up to the charging port.

Of course the charger isn’t a stock Apple power supply; it’s just another Magsafe plug wired into a 5V wall wart. We’re not going to take a guess at what would happen if [Tony] plugged a stock Apple charger into his modded phone, but the mod works perfectly without the danger of ripping a USB port out of his phone.
