Hacking Google Daydream To Work With IOS

December 20, 2016 by Elliot Williams 11 Comments

The Google Daydream is a VR headset with a controller, and according to the folks at Google, “It’s not currently compatible with iOS and won’t be for several years probably.” OK.

This inspired [Matteo Pisani] to get to work on the protocol that it uses to speak with Android phones. Cutting to the chase, he got it working in several days.

There really wasn’t all that much to it. The controller sends data over Bluetooth, and [Matteo] noticed an “unknown” device on the network. Looking inside the data that it sent, it changed when he moved the controller. Not so unknown now! The rest of the work consisted of writing applications to test hypotheses, waving the controller around, and finding out if he was right. Read up if you’re interested in implementing this yourself.

We love protocol hacks here. From running quadcopters on your own remotes, to simply trying to turn on a lightbulb, it’s getting more and more important that we understand the various languages that our devices speak.

Phone-To-Phone Power Thievery

October 30, 2016 by Steven Dufresne 38 Comments

Once again, [Rulof]’s putting his considerable hacking abilities to good use, his good use that is. By modding a few simple parts he’s put together something that he can carry around on his keychain that’ll allow him to steal power from his friend’s phones to charge his own phone.

He starts by cutting away the motor from an iPhone fan to isolate the Micro USB connector. He then removes the charging circuit board from a cheap Chinese USB power bank, and solders wires from the Micro USB connector to one side of the board. Lastly, he cuts away the Lightning connector from a Lightning-to-USB cable and solders that connector to the other side of the circuit board. For longevity and cosmetics, he puts it all in a small wood block and connects a key ring. The result is a small, neat looking box with a Micro USB connector on one side and a Lightning connector on the other. You can see him make it, and then use it to steal power from his friends in the video after the break.

Simple Game Boy IPhone Mod Is Simple

October 21, 2016 by Richard Baguley 10 Comments

We’ve featured the work of [Modpurist] before, but his latest hack is wonderful in its simplicity. He wanted to create a more authentic Game Boy feel on his iPhone, so he printed out and stuck a skin on the front that makes it look like a Game Boy. Or rather, a Phone Boy, as the form factor is a bit different.

By measuring out the on-screen buttons and using light photo paper, he was able to have buttons on the skin as well: the touch screen still works through it. You can download his printable templates… and the finishing touch is a similar print for the back of the phone to gives that genuine Game Boy feel. Okay, feel is not the right term since the classic d-pad and red buttons are still just capacitive and have no throw. But this is a clever step in a fun direction.

Check out his other hacks while you are at it, including the Game Boy Fridge.

Pokemon Go Physical Pokeball Catches ‘Em All

July 25, 2016 by Moritz Walter 12 Comments

There’s something irresistible about throwing Pokeballs at unexpectedly appearing creatures. But wait. When did you actually, physically throw a Pokeball? Swiping over colored pixels wasn’t enough for [Trey Keown], so he built a real, throwable, Pokemon-catching Pokeball for Pokemon Go.

Ever Buy Music From Apple? Use Linux? You Need This Tool

July 21, 2016 by Cameron Coward 38 Comments

Sure, you’re a hardcore superuser, but that doesn’t mean you don’t enjoy the finer things in life — like shiny squircles and getting every new app first. But, what’s an OS-indiscriminate person like yourself going to do when it comes time to purchase music? That’s where the recover_itunes tool shines, and if you’re a Linux user with an iPhone, it might just be your new best friend.

IPhone Polarizing Camera Solves Filter Orientation Problem Using Flash

July 4, 2016 by Jenny List 6 Comments

One of last year’s Hackaday Prize finalists was the DOLPi, [Dave Prutchi]’s polarimetric camera which used an LCD sheet from a welder’s mask placed in front of a Raspberry Pi camera. Multiple images were taken by the DOLPi at different polarizations and used to compute images designed to show the polarization of the light in each pixel and convey it to the viewer through color.

The polarizer and phototransistor taped to the iPhone.

[Dave] wrote to tip us off about [Paul Wallace]’s take on the same idea, a DOLPi-inspired polarimetric camera using an iPhone with an ingenious solution to the problem of calibrating the device to the correct polarization angle for each image that does not require any electrical connection between phone and camera hardware. [Paul]’s camera is calibrated using the iPhone’s flash. The light coming from the flash through the LCD is measured by a phototransistor and Arduino Mini which sets the LCD to the correct polarization. The whole setup is taped to the back of the iPhone, though we suspect a 3D-printed holder could be made without too many problems. He provides full details as well as code for the iPhone app that controls the camera and computes the images on his blog post.

We covered the DOLPi in detail last year as part of our 2015 Hackaday Prize finalist coverage. You can also find its page on Hackaday.io, and [Dave]’s own write-up on his blog.

Apple Introduces Their Answer To The Raspberry Pi

April 1, 2016 by Brian Benchoff 157 Comments

Today, Apple has announced their latest bit of hardware. Following in the tradition of the Raspberry Pi, BeagleBone, and the Intel Edison, Apple have released a single board computer meant for embedded and Internet of Things applications. It’s called the Apple Device, and is sure to be a game changer in the field of low-power, Internet-enabled computing.

First off, some specs. The Apple Device uses Apple’s own A8 chip, the same dual-core 64-bit CPU found in the iPhone 6. This CPU is clocked at 1.1 GHz, and comes equipped with 1GB of LPDDR3 RAM and 4GB of eMMC Flash. I/O includes a Mini DisplayPort capable of driving a 4k display, 802.11ac, Bluetooth, and USB. In a massive break from the Apple zeitgeist of the last decade or so, the Apple Device also includes a forty pin header for expansion, much like the Raspberry Pi, BeagleBone, and Edison.

Although Apple’s first foray into the embedded computing market is a shocker, in retrospect it should come as no surprise; the introduction of HomeKit in iOS 9 laid the groundwork for an Internet of Apple Devices, embedded into toasters, refrigerators, smart homes, and cars. The Apple Device lives up to all these expectations, but what is the hands-on experience like?

See our review of the Apple Device after the break.
