[Becky] wrote in to tell us about her latest hack for Adafruit Industries. This hack will allow you to light up the Apple symbol on the back of your phone, and as she notes, it will definitely void your warranty. From the looks of the video, it requires some extremely good soldering skills, and optionally mid-level tape skills. If you’re up to the challenge, and have the stomach to see your iPhone on the operating table, the results are quite good.
One other challenge of doing this hack is that it uses a kit that Adafruit isn’t going to sell since it uses knock-off Apple parts. They exist somewhere, but where to source them would be a challenge. On the other hand, from a purely experimental/engineering point of view, the video after the break is quite interesting. Many of us would be very hesitant to take apart a several hundred dollar phone, much less solder to a power supply on it!

This super quick hack will be fun to do with the kids. Remember the days of View-Masters? You’d put a disk of small slides into a little plastic viewer and a stereoscopic image would jump out at you in 3D! Now you can not only view stereoscopic images on your smartphone, but make your own too!
To shoot the images just hold your phone in portrait orientation and take a snapshot of your subject, then move the camera six inches to the right and take a second image. The two pics need to be displayed on the screen at the same time and for this [Plarky] uses a free iPhone app called Pic Stitch. We’re sure you can find an Android equivalent in no time if you do a bit of searching.
To view the stereoscope it helps to make a divider out of cardboard like the one seen above. You’ll need to cross your eyes and focus on a point to bring the two images together. We don’t remember having to do this with the View-Master so we’re hoping someone will take the idea and improve upon it. We’ve already seen a digital View-Master. Now we want to see those dual screens replaced with an iPhone cradle.
The Raspberry Pi foundation is in a somewhat unique position. They always test the units that get returned to them in hopes that they can improve the design. They often request that the power supply also be sent back with the RPi unit, as we know the board will not work well if the PSU can’t source enough current. And so they’ve been able to get a look at several counterfeit iPhone chargers. This is not one of the recommended ways to power the RPi, but their ability to collect failed hardware means that they have identified three different fakes on the market.
Seen here is a genuine Apple product on the left. The others are fake, with the easiest way of spotting them being the shiny chrome plug connectors. The genuine part has a matte finish on the connectors. There is also a difference in the chamfering, and even a variation on the orientation of the USB port on some of them. Unfortunately we don’t get a look inside, which is what we really wanted. But you can see in the video after the break that weighing the adapter will also give it away as a fake, showing that the components within probably vary quite a bit. This reminds us of some other fake PSUs that have been exposed.

This is a simple iOS debugging tool that will take no time to solder together. There’s even a chance that you already have everything you need on hand. The hack simply connects an RS232-to-USB converter to a breakout board for an iPod connector.
The hardware is aimed not at stock iOS systems, but as an aid to those who wish to run alternative operating systems on them. When the OpeniBoot package is run on an iPod Touch or iPhone it enables a serial terminal on pins 12 and 13. The FTDI breakout board takes these as RX and TX and makes them available to your terminal program of choice via USB. Speaking of USB, you may already have noticed the black cable leaving the right side of the image. Using the terminal doesn’t limit your ability to use the device’s USB functions.
[Zitt] has a security camera which will send him messages any time it detects motion. However annoying this might seem, we’re sure he has his reasons for needing this much immediate feedback. The real problem comes when he goes to view the feed on his iPhone. His solution is to turn the camera’s notifications off, and use his own script to transcode a clip and shoot off an email.
As you can see above, the end result is a concise email that includes the recently captured clip, as well as links to the live feed. He has been storing the clips on an LG N4B2 Network Storage Server (NAS) and since he’s got root access to the Linux system on the device it was an easy starting point for the new system. After he compiled FFmpeg from source (which handles the transcoding) he started work on the script which backs up the recordings and sends the email messages.
One thing he wants to add is a method to clear out the old backup videos. Having encountered a similar issue ourselves we decided to share our one-liner which solves the problem. Find it after the break.

[Jake von Slatt] is at it again; putting his own artistic spin on ordinary items. This time around it’s the glass on the back of an iPhone. It kept breaking and after a few replacements he wanted to try to replace the glass with a piece of etched brass. But part way through that experiment, he figured out how to use toner transfer to develop these stunning custom iPhone glass back plates.
The first step is to source the correct replacement back for your phone. These are made of two parts, the glass and a plastic backer. By carefully heating and wedging the two parts with some popsicle sticks he was able to separate the pieces. Next, he cleans and buffs the glass, preparing it for the artwork he is about to apply. Toner transfer paper, just like that used for PCB resist, is used to print and adhere a design to the underside of the glass. From there he hand paints over the black outline to achieve the results seen above.
It takes time and patience, but shouldn’t be any harder than etching a circuit board.
At the beginning of the school last year, [Ryan] needed to come up with a project for his master’s thesis. Having a bachelor’s in mech. engineering and doing his graduate work in software engineering allowed [Ryan] to do something really cool for his thesis; he decided to turn an iPhone into an autonomous robot with live video streaming, remote control, and object detection.
[Ryan] started building his ArduiPhone last October with an Arduino, motor shield, and a Magician Chassis. The software is based on an iPhone network programming tutorial that opens a socket connection to a desktop PC and relays commands to an Arduino serial port.
One of the more interesting features of [Ryan]’s ArduiPhone is the ability to stream video directly from the phone to a Java application. Instead of FaceTime, [Ryan] streams videos by converting an image from the front-facing iPhone camera to a byte array, sends it over the network, and decodes the image in a Java app. It’s low-level stuff, but the video quality is excellent and something we’ll probably be seeing more of in the future.
As always, videos after the break.
