In 2006, Defcon 14 premiered a unique electronic badge. All it did was blink, but it raised the bar for what was expected from a hacker conference badge. In 2007, they went from 2 LEDs to 95 in a scrolling marquee. Along with a POV mode, the badge had two capacitive switches to let the user edit the displayed text. Defcon 16′s badge featured an IR transmitter and receiver for transferring files from an SD card. It worked as a TV-B-Gone and had pads to access a USB bootloader. That was the same year that The Last Hope debuted their RFID tracking badges.

This year the official Defcon badge reacted to sound, but they were no longer the only game in town. Ninja Networks brought their 10 character party badges with a built in debugger. The Arduino compatible HackTheBadge 1.0 also made an appearance. With these new entrants into the field, we wondered what you’d want to see in your ideal badge. What badge would you want to see at next year’s Defcon? Leave you comments below and keep in mind that it should be an idea that is easy to cheaply mass produce.

UPDATED: Forgot to mention the Neighborcon 2 badge based on the GoodFET20.

Boxee, the free media center management and streaming application, is now available for Windows platforms. We’ve been following the developments of Boxee since we first announced its alpha this time last year. At that time, it was only available for OSX with promised Ubuntu support. We were a bit skeptical about the interface noting, “Unfortunately all the dynamic resizing, animated, sliding, floating info boxes make it behave like the zooming user interface’s retarded cousin”. Our interest in Boxee was almost entirely based on it being a fork of XBMC, the media center project developed for initially for hacked Xboxes. It was interesting to see Boxee become the interface of choice for hacked Apple TVs and then go mainstream with a big push at CES.

Have you been using Boxee as your media center? What do you love/hate? What about alternatives like XBMC, Plex, or MythTV?

Joystiq has been tracking the new starlet of Xbox 360 failures: the E74 error. It appears as the lower right light on the console turning red and an on-screen message telling the user to contact support with the error E74. The number of reported E74 errors seems to have risen since August 2008 and people are wondering if the more recent increase in errors are related to the release of the New Xbox Experience (NXE) Dashboard update. Did Microsoft reclass Red Ring of Death (RROD) failures as E74 to avoid warranty replacements?

From day one, the Xbox 360 has been plagued by hardware failures. So many failures that Microsoft ended up pushing the 90 day warranty up to a full year. Less than a year later they acknowledge the systemic RROD problem and extended replacement for affected consoles to three years. The RROD is named because of the three red lights displayed when the console failed. The culprit appears to be poor cooling of the console’s components. Components like the GPU would overheat causing solder joints to fail. People were able to repair their own consoles by reflowing with a heatgun. Microsoft has never officially disclosed why these systems fail. Our console purchased on launch day RROD’d, but [bunnie]‘s solder joint inspection of it proved inconclusive. Every Xbox owner on Joystiq’s staff has had an RROD.

The E74 error is apparently not new. While Microsoft officially calls it a “general hardware failure“, users have been calling it a general video error since launch. It can occur when you have a bad video cable attached to the console. Users are blaming the HANA video scaler chip for the latest issues. There have been five different motherboard versions of the Xbox 360 so far. Each version upgraded the cooling and/or the size of the GPU and CPU. The HANA chip was introduced when the consoles started supporting HDMI. The original ANA video scaler on the Xenon board was a quad-in-line style SMD package with pins around the perimeter. The HANA chip on newer board designs is a ball grid array (BGA) package, which means it can fail the same way the GPU does for an RROD.

Did Microsoft change the error reporting on the Xbox 360 so they’d replace fewer consoles? No, we don’t think so. Is this a similar hardware failure? Most certainly. Unfortunately, E74 errors are only covered under a one year warranty instead of the RROD’s three year despite it being the same failure mode. Why are so many E74s happening now? There aren’t any hard numbers on how many failures there have been or how it compares to the RROD. We think that it’s just a result of more people having Xbox 360s with HDMI support now. A large portion of the Xenon 360s have been replaced with more reliable HDMI consoles, but that just means a larger install base of E74 prone consoles. More consoles means more possible failures.

RFID seems to have invaded every part of our lives. Sure, the technology has been primarily used in government and industry, but that doesn’t mean that it doesn’t have consumer applications. Recently, we posted about [max's] RFID dorm room lock, that he built to provide a safe, convenient way to access his room. A while back, we talked about an RFID spatially aware address book that used a combination of rfid tags and post-it notes to control the NFC enabled Nokia 3220 cell phone. Both of these projects highlight unique applications where RFID is used. We bash on RFID from time to time, mostly due to its security (or lack there of). That said, there is an interesting consumer solution out there for people who want to voluntarily use RFID called Touchatag (formerly known as Tikitag). The cool thing about Touchatag is that it uses a combination of RFID and QR (2-D barcode) tags to trigger applications on the Touchatag website. The starter kit, which includes 10 tags and a USB RFID reader, goes for about $40; a decent price considering the hacking potential for the RFID reader. In addition to using the reader, you can also use any NFC enabled phone to read the tags. While NFC enabled phones are currently few and far between, the technology will likely be implemented in many of the new phones released in the coming year.

We’re curious, what do you think is next for consumer RFID? What kind of innovative project ideas do you have?

We spotted this odd piece of geek couture on DVICE today. It’s a bracelet that displays incoming calls via Bluetooth and also vibrates. The intended use is kinda interesting, but we wonder what else could be done with it. Could you update it with any text you want by creating fake caller ID messages? You could have your laptop in your backpack and have the bracelet update when it finds an open access point or any other sort of notification. The display shows the word “Connecting” in pictures, but apparently only displays numbers for incoming calls. It also includes a button to reject calls.

Do you have a project that needs a wireless display? Are there other options like this? At $25, this might be worth a try.

An anonymous Slashdot reader asked today what was the best digital television to analog converter box. He was looking for one with the best hacking potential. We actually purchased a Zenith DTT900 HD converter box this summer specifically wondering about the hacking potential. We did a teardown and you can find a full gallery on Flickr. Our conclusion was this: there’s not much there. You’re talking about a box that takes a digital RF signal and turns it into a crappier looking analog signal over composite. There isn’t much you can do outside of its designed use. Do you have any ideas what else can be done with it?

Slashdot commenter [timeOday] did mention a Tivax brand box that features a serial port. You can use it to issue remote commands to the box.

Not much has been said about the actual coupons. We’ve got a scan of them embedded below. The $40 coupons are essentially credit cards. We ran ours through a magstripe reader confirming this. Even though the card isn’t stamped with the recipient’s name, it is stored on the magstripe.

Gadget blogs have been a fluster the last day about TechCrunch stating that netbooks “just aren’t good enough“. Writing a response post hasn’t proven very hard given the number of factual errors in the original. Boing Boing Gadgets points out that the low-end of the spectrum that TC post seems to cover are almost impossible to purchase because they’re so outdated. Liliputing rightly states that comparing the browsing experience to the iPhone isn’t worthwhile since it’s entirely a software problem. Laptop goes so far as to recommend the HP Mini 1000 and Samsung NC10 specifically for their keyboard. TechCrunch isn’t alone in their opinion; this week Intel stated that using the ultra portable devices was “fine for an hour“. TechCrunch is designing a web tablet right now using the collective wisdom of blog commenters. Looks like they’re just reboxing a netbook for the prototype.

We cover the netbook market for different reasons than most: Their low low price makes people much more willing to hack on the device. For the price of a smartphone, you’re getting a fully capable laptop. The low performance doesn’t matter as much since we’re running different flavors of Linux that are much lighter than Windows. People running OSX86 are doing it to address a market that Apple doesn’t.

What’s your experience with netbooks? Do you have one that you adore or are you annoyed by their shortcomings? Models we’ve covered in the past include the Acer Aspire One, Asus Eee PC, Dell Mini 9, and MSI Wind.

When Boing Boing Gadgets posted about this $13 robot hand music box, we immediately thought “OH EXPLOITABLE!”. Over the years, we’ve acquired quite a bit of cheap trash just operating under the assumption that we would turn it into something else. Most of our acquisitions are Woot‘s fault. Just this morning we were dismayed to find out that the purveyor of cheap electronics had already sold out of animatronic Elvis heads. Now that would have been fun. We’ve purchased things like Tony Hawk helmet cams, jumbo remotes, Bluetooth headphones, Gyration mice, IMFree chatpads, and many other items of questionable use thinking that some day we’d use it. How about you? What sort of irrational purchases have you made and what would you do with a $13 mechanized hand?

[Just as we were wrapping this up, Woot posted a $49 HMD; you better believe we bought that.]

• thin as possible
• touch screen (except for power button)
• WiFi
• video camera and low-end speakers
• 4 Gigabyte hard drive
• 1/2 Gigabyte of RAM
• Linux and Firefox (in kiosk mode)
• no desktop interface

We are not completely sure that this device does not exist in some form. Tablets have been around for a while and many cover most of these features. Consider the Nokia N800 or the Pepper Pad.

We also think the TechCrunch readers, who generally concern themselves with what they can buy rather than what they can make, are not really the best crowd for this job. Considering our reader’s abilities to do things on the cheap, we thought we would pose the question ourselves with our own spin. What old and cheap hardware could you re-purpose to create this product?

When working on a Mac, we find that Handbrake works really well. It is intuitive and efficient, featuring useful options and a virtually nonexistant learning curve.

Options on a PC are far more diverse. Our goto app is DVD Shrink: finding the download is a little tricky, but once installed, it makes ripping and burning a snap. We really love how easy it is to alter the compression of audio and video, and selectively include or exclude extras, menus, audio streams, and even legal warnings. We only have 4.7GB to work with, so we make space where we can.

When the source DVD is under the size limit, we prefer not to alter it in any way; for this, we use Alcohol 120. It is capable of creating nearly identical copies of any DVD, even copyrighted DVDs or video games.

It is entirely possible, likely even, that all you’re interested in is ripping. There are entirely too many options to name them all, but we are partial to DivX for rip-only operations. It is cross-platform, easy to use, and encodes in the DivX format. Playback is another issue (cough – FFDShow – cough). One of the most accessible ripping options, though, is an often ignored but useful app: Nero Vision. It is part of the Nero 8 suite, and although it is officially DVD authoring software for beginners, it features a functional ripping option that encodes ripped files in MPEG2 format. This is truly useful if you intend on authoring custom menus on the destination DVD, although Adobe Encore is a far better option for the actual authoring.

The great variety of options is part of what surprised us at the popularity of the low tech solution. Still, given the variables (level of user proficiency, platform, destination media, etc.), we wouldn’t be too surprised if our readers all vouched for different methods. That’s the question: what method do you use to rip DVDs?

The main problem with the current design is that you have to hit the table hard enough to make a noise the mic can pick up. The ideal solution would be able to detect anything, no matter what the material or how forcefully it was set down. How would you detect objects being placed on the surface (table doesn’t have to be wood)?

A used 1st generation iPhone is actually a pretty attractive device. It’s already been laid wide open by hackers so you can run pretty much anything you want on it instead of waiting for the App Store to tell you what you can and can’t do. You could use it as a WiFi Voip phone, a simple web pad, run an NES emulator, use it as a musical instrument, or build an army of robots.

What will you do when the price of used iPhones bottoms out?

By the way, the best five submissions will get a chance to win a secret prize that I’ll be announcing around the end of next month.

Iceware via rapid prototyping: As we type this post, [Bre] is in the background attempting to build a RepRap style rapid prototyping machine that will construct shot glasses on demand. We were thinking it would be neat to cut beverage glasses out of blocks of ice using a milling machine, but why stick with normal milling equipment? It’s ice right; you could be doing something stupid like using a butane torch for your working tool. We then began to wonder “Has anyone built an ice based rapid prototyping machine?” You could just deposit water on a frozen surface to create your glassware. A group at the University of Missouri has been investigating “rapid freeze prototyping“. Since they’re using water, they only have to create the frozen shell of the part and then fill in the empty cavity with water to create a solid.

Industrial flare bot: Use two large industrial arms to perform cocktail flare moves. This is a similar idea to the juke_bots, industrial DJ bots. The goal would be to put on a good performance while attempting to appear less robotic than Tom Cruise; shouldn’t be too hard.

The separator: There are a few cocktails out there that are carefully poured so that they appear layered when served. We’d love to see a bot that clumsily mixes all of the ingredients together and then runs it through a centrifuge to create the desired product.

Those are three of our ideas. Leave your cocktail robotics ideas in the comments-this whole discussion reminds me of those garbage disposal based margarita machines we saw a couple years ago.
