Experimental music iPad dock

You can buy nice audio breakout equipment for your iPod if you don’t mind breaking the bank. This is partly because the demand is not incredibly high so commercial breakout hardware doesn’t benefit from volume discounts. But it’s also because Apple charges licensing fees for third-party accessories (often referred to as the “Apple Tax”). [Reed Ghazala] decided to side-step the whole situation by building his own accessory which he calls the iPad Audio Desk.

It all starts with a breakout board. The PodBreakout Mini provides an easy to solder interface for the iPad, and ensures that the repetitive act of plugging and unplugging the connection doesn’t break a solder connection. From there [Reed's] enclosure finishing skills take over. The shape and curve of the aluminum sheet give the look befitting an expensive tablet device. Along the back you can see the jacks for line-in, line-out, video, mic/guitar, and headphones that make the dock useful. It wouldn’t be hard to make one… but it might be hard to make one look this great. See for yourself after the break.

Breathing new life into a broken iPod

ipad_nano_button_fix

[Craig] had a busted 2nd Gen iPod Nano that was well out of warranty. The play/pause button no longer worked, leaving him unable to play or pause music, nor power off the device. He didn’t want to scrap the iPod, so he figured out a way to add an external play/pause button instead.

He ordered an iPod dock connector from SparkFun and found that it had just enough space inside for the electronic components he would be adding. He consulted some online references for pinout information, then got busy cramming an ATiny13 and a pushbutton into the dock connector.

To minimize the drain on the iPod’s battery, he puts the ATiny into sleep mode when it is not being used. When the button is pressed, it wakes up the microcontroller and sends the proper signal to the iPod. Based on his estimations, it would take nearly 250 years for the ATiny to drain the iPod’s battery completely, so he’s pretty comfortable leaving the dongle attached at all times.

If you have an iPod with similar issues, he has made his source code available so you can save yours from the trash heap as well.

Cellphone charger has a USB port forced upon it

We still can’t figure out why a standard charging scheme hasn’t been developed for handheld devices (other than greed). Certainly we understand that many devices have different electrical needs as far as voltage and current are concerned, but we still long for the ability to use one charger for many different doodads. [Rupin] is trying to narrow down the number of dedicated chargers he uses by adding a USB charging port to his Nokia cellphone charger. Since the USB standard calls for regulated 5V a hack like this can often be done just by patching into the power output coming off of the voltage regulator in the plug housing of the device. [Rupin's] charger had 5V printed on the case, but when he probed the output he found well over 8 volts. He added a 7805 linear regulator to get the stable output he needed, then cut a hole in the case to house the connector.

Since [Rupin] wants to use this as an iPod charger he couldn’t just let the two data lines float. Apple uses a specific charger verification scheme which requires some voltage dividers to get the device to start charging.

Repair stuck iPod Nano buttons

A system is only as strong as its weakest link and [Roberto Barrios] found that on the sixth generation iPod nano the buttons are the problem. It makes sense that the buttons would be exposed to wear since they’re movable parts. The issue isn’t one of contacts or springs wearing out, but how the buttons are assembled. Each consist of a couple of parts; the tactile piece that you see and press, the electrical switch which converts that force into an electrical signal, and a shim that bridges the gap between the two.

After two months of use the iPod [Roberto] was fixing had stopped responding to presses of the Power button. It turns out that the shims are attached with double-sided tape. Inspection of the internals revealed that the shim had slid to one side and no longer made contact with the electrical system. His solution was to remove the tape and clean off the goo, then reattach the shims using “two-part metal cement”.

With the shim back in place all is well but he made sure to execute this fix on all of the buttons before reassembly.

CES: Where are they now? CES of course!

CES is a time for showcasing the latest and greatest innovative products. While the crowd milled around the iLounge there was one company who stood out amongst the rest. [Mike] from CableJive is making his debut on the biggest stage for innovation this year. Many of you will remember [Mike] from a post back in 2006, where he was fed up of with all of the good docks being for the apple products exclusively. He set out to fix this and, when talking with him, attributes his success to the coverage Hack a Day did on his project. CableJive has become so popular that he has hired staff that help him produce his products. All detailed information for their products can be found at their website.  The finished product is displayed after the break.

iPod nano 6g closer to being cracked

[Steven Troughton-Smith] figured out how to push signed firmware through to the iPod Nano 6g. This is accomplished by modifying iRecovery to recognize the device on the USB after forcing a recovery mode reboot. So no, this doesn’t mean that it has been cracked since it checks the firmware you push and reboots if it’s not approved. But if you can figure out how to craft a custom image that passes the check you can call yourself a jailbreak author.

New A4 jailbreak debacle puts the brakes on for iPad

If you’ve been waiting in the wings for the next Jailbreak to be release you should know there’s been a bit of a speed bump. [ChronicDevTeam], which has been working on an exploit for A4-based iOS devices called SHAtter, tweeted last Thursday that the fully tested, untethered, and unpatchable package knows as greenpois0n would be released today. But on Friday [Geohot], who you may remember from the PlayStation 3 Hypervisor exploit, rolled out his own mostly untested and admittedly beta jailbreak called limera1n.

So where does that leave the situation? Because [geohot] used a different exploit, the [ChronicDevTeam] decided not to release greenp0ison. If they did, it would give Apple a chance to block two different exploits. Instead they are working feverishly to incorporate, test, and repackage using the same exploit as limera1n.

If you don’t want to wait, jailbreak now, but you risk problems with an unstable exploit method that is only available for Windows.
