Nike + IPod As A Tracking Device

[Thomas] found a paper from 2006 that describes using the Nike + iPod system as inexpensive tracking devices. Yep, it’s old as dirt but we think it’s fascinating reading! [Scott Saponas] and his fellow authors take a hard look at the lack of security in the system in a twelve-page PDF. They cover several different ways to capture and track one of the $29 tags in someone’s shoe, including using the Gumstix reader above, or a slightly modified 3G iPod. If the sensors are not removed or manually switched off when not in use they can be picked up by any RF reader within range. Because the tags are cheap and available, one could be planted on an unsuspecting victim James-Bond-style. Maybe this is what prompted Apple’s half-hearted attempt to restrict hacking the devices to do things like unlock doors.

Of course if you don’t want to do the reading you could download their video presentation or just stream it.

Report From ESC Silicon Valley 2010

Ah, the heady aroma of damp engineers! It’s raining in Silicon Valley, where the 2010 Embedded Systems Conference is getting off the ground at San Jose’s McEnery Convention Center.

ESC is primarily an industry event. In the past there’s been some lighter fare such as Parallax, Inc. representing the hobbyist market and giant robot giraffes walking the expo. With the economy now turned sour, the show floor lately is just a bit smaller and the focus more businesslike. Still, nestled between components intended to sell by the millions and oscilloscopes costing more than some cars, one can still find a few nifty technology products well within the budget of most Hack a Day readers, along with a few good classic hacks and tech demos…

Arduino IPod Library Work Continues

[David Findlay] has been hard at work on his Arduino iPod remote library and is now showing off some Wii Nunchuck control in the video after the break. When we looked in on his work in September he was using a Staples Easy Button to control the iPod. Now he’s added all of the functionality for iPod simple remote mode, and most of the advanced mode.

Advanced mode works well with his iPod Photo but the iPhone just returns errors. We know that Apple uses some tricks to keep unauthorized accessories out, so we hope that [David] finds a way to sniff out the necessary accessory protocols from an approved model.

Raise Your Hand If You Want To Listen To Something Else

This track is awful, someone skip it! This project does just that with a wave of your hand. A laser beam shines across a room and, when obstructed, it sends a command to an iPod. One wave pauses playback, two waves skips to the next track, and a constant obstruction jumps backward one track.

They’re using a textile-compatible electronics platform called Schemer. This is the first time we’ve run across this product which uses a modular system to connect devices via a 1-wire communications bus.

No matter what hardware you use the concept is what interests us. There’s no shortage of iPod remote projects to draw on as examples. This method seems a bit more fun than banging your head for track changes or slapping wildly at an over-sized remote. We’re just a bit concerned about the power consumption of the laser-pointer, perhaps an IR beam would be a more economical choice?

IPod Shuffle Headphone Remote Reverse Engineered

The headphone remote for the third generation iPod shuffle has a special chip that identifies it to the iPod itself. [David Carne] posted an in-depth report about the process he used to reverse engineering that protocol. He’s discovered that the remote uses a peculiar signal to identify it as authentic when the device powers up. We’ve talked about Apple’s use of peripheral authorization before and it seems this is no different. [David] did manage to emulate the authentication using an ATmega88. If you’ve got a shuffle 3G sitting around this info will allow you to operate it with a microcontroller in your next project.

Internet Controlled Scrolling Numitron

How’s this for a first microcontroller project: a ticker that pulls messages from the Internet and scrolls them on a set of numitrons. [David Barton] built this using an mbed microcontroller. Tapping an ethernet library he got this to pull data from his server by connecting directly to the cat5 cables. The display consists of three numitrons which are incandescent 7-segment displays. In the video after the break you can see him sending messages to it from his iPod touch. This is just a PHP form that writes the submitted message to a file for the mbed to read. As [David] points out, there’s obvious Twittering applications here, but we just like the way it looks! Continue reading “Internet Controlled Scrolling Numitron”

Repurposing A Click Wheel

We think the click wheel is the biggest contributor to the success of the original iPods. The devices were a brick with a monochrome screen but the user interface was slick and easy to use. [Jason] decided he wanted to add a click wheel to his own project. After using a logic analyzer he discovered that it doesn’t implement a common protocol such as I2C, perhaps a deliberate move by Apple to keep the controller under wraps? He managed to get past this hurdle, as seen in the video after the break, by bit-banging the data in from the click wheel and then reverse engineering the protocol.

It’s connected to an AVR ATtiny88 with feedback shown on a character LCD screen. We’re glad that [Jason] tipped us off about this, but he doesn’t have any code available yet. We love to dive into the source so the sooner he gets it up the better! We’ve got an old 3rd generation with a bad board that is begging to have the wheel ripped out of it, not to mention the dirt-cheap replacements available on ebay.
