A regular complaint over at Instructables is that not everybody can afford their own laser cutting rig. If DK Ahn has his way, however, precision cutting – of at least paper, wood and polypropylene under 2mm thick – would be available to the mainstream, thanks to his MOW microfactory.
The MOW is a tabletop cutting machine, that sits on a desktop and moves itself via four tethered anchors. Patterns would be downloaded and beamed over to the MOW via Bluetooth, which would then shuttle around slicing through the plastic or whatever material it was dealing with.

While the glossy device in the image above is merely a concept render, DK did put together a working prototype. Made from bits of remote-controlled cars, plotters and other recovered gadgets, you can see the prototype in action in the video below; if you want to skip to the action, start watching from around 8:35.

Not, perhaps, the sort of thing most SlashGear readers will be able to try at home, but if you’ve ever wanted to see a 15 tonne hydraulic grapple controlled by a humble Wiimote then here’s the video for you. Simon Wittber of Australian firm Transmin is lucky enough to have not one but two remote-controlled grapple arms, each toting a vicious looking six-claw pincer, and so he and his team decided to link up Nintendo’s controller for some afternoon entertainment.


Each grapple can make roughly twelve revolutions per minute – that’s about 72kph or 45mph – and has a sixteen meter reach. The team used Python to link the Wiimote (via Bluetooth) into their normal grapple control system.

As an aside, Simon’s voice-over and the choice of music is perfect. He sounds like just the sort of calm, level-headed person you’d want wielding a 15 tonne grapple with the casual flick of a Wiimote.

The iPhone Dev Team have updated their redsn0w jailbreak and ultrasn0w carrier unlock tools to work with the iPhone 3GS, citing the release of rival app purplera1n as forcing their hand. The Team had originally intended to wait until iPhone 3GS adoption was more widespread before distributing their tools, in the hope that it would give Apple less time to close the security hole on which the unlock depends.

“We realize we upset some folks (e.g. existing 3GS owners) with our earlier announcement that we wanted to hold onto the 3GS iBoot-family hole until 3.1 was out. Our aim there was to get as many people as possible onboard (within reason of course) before revealing the hole, since Apple will fix it immediately. But all of that became moot when the purplera1n release was made, since it uses the same hole” iPhone Dev Team

Those wishing to unlock their iPhone – and keep it unlocked – are still being warned to avoid Apple’s official baseband updates. The Cupertino company has apparently stepped up its efforts to remove loopholes such as the one which enables this latest version of ultrasn0w.

Going by the comments over at the Dev Team blog, however, Apple retaliation is not the only problem some users are facing. Some iPhone 3GS owners are experiencing poor signal reception after unlocking, or an inability to connect to WiFi networks, while others claim their handsets have been left bricked or show significant battery drain. Now seems as good a time as any to warn that Apple are unlikely to perform warranty repairs on any iPhone they believe has been tampered with, so you attempt a jailbreak or carrier unlock at your own risk.

We can’t say we looked at the Sharp Mebius NJ70A netbook – with its nifty touchscreen trackpad – and thought “what this needs is a second touchscreen”, but then we’re not SKY at UMPC Fever. After unboxing the N270-based netbook, he loaded up Windows 7 and then installed a touchscreen layer so as to use handwriting recognition direct onto the 10-inch display.

Interestingly, while he had the NJ70A open, SKY discovered that the optical trackpad actually has its own processor and RAM, meaning it doesn’t rely on the netbook’s own Atom CPU. He’s now trying to identify exactly what those mysterious components are.

Other hardware details include two RAM slots inside, which makes upgrading from the standard 1GB straightforward. XP will only recognize a maximum of 2GB; Windows Vista will recognize 3GB; and Windows 7 will recognize 3GB but only allow you to use 2GB.

Reminding us of Thermaltake’s monster Level 10 PC case, this is actually the Edelweiss PC, the handiwork of Pius Geiger and in fact initially constructed all the way back in 2006. Updated this year with a crisp new white color-scheme, the water-cooled Edelweiss separates out drives, graphics and power-supply, and then illuminates them with a discrete but effective lighting system.
Full hardware specifications of the PC are unknown, but the Edelweiss PC does have a FATAL1TY motherboard, dual graphics cards and a DVD burner. We’re assuming that along with the color update, Pius also slotted in some more impressive hardware to take advantage of the heavy-duty watercooling system, too.

Add in the excellent cable-routing, and you’ve got a mind-blowing case mod. No word on how much all this cost, nor how long it took, but we’re guessing the answer to those questions are something like “a lot” and “a long time”.

The iPhone Dev Team have announced that they are delaying the release of the updated ultrasn0w iPhone 3GS jailbreaking and unlocking tool. In a post on the Team’s blog, they detail the nature of the exploit used to jailbreak (and then unlock) the 3GS, a loophole which Apple could readily close once it was made public.
“Here’s the critical point, the reason why we’re delaying our version of the jailbreak: Once the jailbreak is out, Apple will fix the iBoot-family bug we use to accomplish it. They will simply stop signing the old iBoots and only sign the fixed ones. If you bought your phone after Apple has done this, there’s nothing you can do…the jailbreak isn’t going to work for you.” iPhone Dev Team blog

According to the Team, the exploit depends on an iBoot-family bug, which can only be addressed if users have a signed iBoot-family img3 from their own device. This contains their ECID, a unique chip identifier different on each iPhone 3GS. If Apple discover the loophole, they could update the smartphone and refuse to sign any old iBoots; then those users would not be able to jailbreak or unlock their handsets.

The Dev Team are counting on an imminent iPhone OS 3.01 update which addresses some of the platforms more buggier aspects, and are waiting until then to see the state of play. They’ve given no indication of when the iPhone 3GS jailbreak and unlock option might be released, a situation that’s prompting no small amount of revolt in their comments.

Owners of the new iPhone 3GS will soon be able to jailbreak and unlock their smartphone, thanks to a five-month-old security flaw in the handset’s baseband. The iPhone Dev Team have verified that Apple have not addressed an exploit known as 24Kpwn that was originally identified in the iPod touch 2G; with it, they will be able to upgrade their ultrasn0w tool to work on the iPhone 3GS.
The loophole arose, the Team believe, because Apple finalized the iPhone 3GS’ bootrom in around August 2008, months before the exploit was identified for the iPod touch 2G. 24Kpwn went on to be exploited in the redsn0w tool, and similar techniques can now be implemented in ultrasn0w.

It will take some time to update ultrasn0w with the new system, but once completed it will mean the iPhone 3GS can not only be loaded with unofficial apps but used with any SIM card. Apple are likely to release a firmware update to try to prevent any damage, so the Dev Team are advising that people avoid baseband updates.

Developers playing with Palm’s webOS have discovered a method whereby software can be installed on an unhacked Pre. The system emails a .ipk link to the app, and seemingly takes advantage of a loophole in the platform to bypass Palm’s security.

For the end-user, installing an app is as straightforward as tapping on a link in their email and allowing the Pre’s browser to open it. That automatically downloads and installs the software; currently the only publicly available app is a proof-of-concept that installs a non-functional shortcut icon to the Pre’s launcher.

Frankly, we’re fully expecting Palm to step in and put a stop to this sort of software distribution with an update to webOS. Not only does it present a security risk, where naive Pre users may click to load a malware app without realizing, but it bypasses the official app store and thus denies Palm themselves any cut of paid-app profits (or the ability to decline certain apps it doesn’t want released). They’re likely to put more emphasis on the security reasons, though.

You’ll need more than a passing familiarity with the Dell Inspiron Mini 9 to spot the mod here, so we’ll give you a hefty hint: it’s the fingerprint reader in the right-hand side of the palm-rest. MyDellMini forum member Rich decided he wanted biometric login functionality in his netbook, so inserted the guts of an Eikon fingerprint reader into the Mini 9.

To do so he also had to squeeze a USB hub inside, so as not to lose one of the Inspiron Mini 9’s external ports. After some careful measurements, he cut a narrow slot into the palm-rest, and then gave it a suitably beveled edge to allow contact between finger and sensor.

Considering you can pick up the Eikon for under $40 through Amazon Marketplace, this doesn’t have to be an expensive mod, either. Next step for the Mini 9 – which as you can see is already running Mac OS X – is an internal GPS receiver.

It hasn’t taken hackers long to enable unofficial tethering on iPhone handsets running OS 3.0, and its taken carriers even less time to put out the predictable dire warnings regarding anyone found using such hacks. UK carrier and official Apple iPhone partner O2 have issued a statement suggesting that anybody found using tethering without their official “Bolt On” package will be charged or disconnected.

“Internet rumours suggest that some customers have modified their iPhone to enable Internet Tethering without the purchase of the Internet Tethering Bolt On. Any use of this particular feature without the purchase of the Bolt on is specifically prohibited under our terms of service.

Under those terms we reserve the right to charge customers making modem use of their iPhone or disconnect them. If customers wish to use the Internet Tethering feature on their iPhone 3G or iPhone 3G S, we recommend taking the Bolt On which is available from Friday 19 June” O2 statement

The carrier has been less forthcoming about how they will check for unofficial tethering use, though it seems likely that anybody with high traffic rates will stand out and be investigated. Like other carriers, O2’s so-called “unlimited” iPhone data package actually has a 3GB limit, and they closely monitor traffic for signs of P2P or VoIP use.

Arguably, O2’s stance is more understandable than, say, AT&T. At least the former offers a tethering package in the first place – albeit an expensive one, charging £14.68 ($24) for 3GB per month or £29.36 ($48) for 10GB – whereas AT&T won’t offer official tethering at all until later in the year.

As we know, iPhone OS 3.0 brings with it the potential for tethering on your Apple smartphone, using the handset’s 3G connection to get your laptop, netbook or other mobile device online while on the move. Apple have done all they can to make it straightforward – you can tether over USB or Bluetooth, with minimal setup - but the carriers seem less enthused. Some, like AT&T, don’t officially support it yet, while others, such as O2 in the UK, will allow you to tether but have an expensive extra data plan you need to add.

One thing we know about iPhone users, though, is that if you show them a sign saying “no entry” they’ll work out a hack to enable it, and sure enough there’s now a simple way to turn on iPhone tethering no matter your carrier or tether-plan status. All you need do, in fact, is visit help.BenM.at on your iPhone and install a new local carrier profile configuration file.

There are files for tethering on multiple carriers – not just the official Apple partner in each company, but rivals for those using their iPhone unlocked – and more apparently being added all the time. Plus, there are install files for MMS support, including AT&T who have previously said that they won’t be officially enabling it on the iPhone until late summer.

This is one of those cases where “because you can” might not mean “you should”; carriers have been very clear now and previously as to the fact that tethering data is not considered part of an “unlimited” on-device data package. If you do attempt it – and obviously there’s also risk in installing any software from an unknown site – then bear in mind your carrier will likely be monitoring data traffic to identify any unofficial tethering or MMS use.

The iPhone Dev Team have released a video demo of their latest unlocking tools, including yellowsn0w, doing its magic on an iPhone 3G running OS 3.0 which is set to be released sometime in the next 24 hours. They’ve also revealed the development of a new tool, ultrasn0w, which they claim should be able to unlock any iPhone to-date, running any OS version.


yellowsn0w will get its release shortly after Apple push out iPhone OS 3.0 – the Dev Team are being cautious, so as not to give Cupertino’s engineers any time to scupper the jailbreak/unlock setup – but ultrasn0w won’t see daylight until Friday at the earliest. There’s no telling right now as to whether the iPhone 3G S can be jailbroken and then unlocked.

As ever, the tools to do all this will be free – if someone is trying to charge you, they’re not legit. In the video below, skip to around the two-minute mark to see the actual unlock demo.

Security researchers are claiming to have found a way to run non-approved code on iPhones that have not been jailbroken. Charles Miller, a principal analyst at Independent Security Evaluators, and Vincenzo Iozzo, a student at the University of Milan in Italy, have discovered “more than one” technique for loading an application into a factory iPhone as a non-executable chunk of data, which then flicks over to an executable and could potentially be used to monitor the smartphone, listen in on calls or harvest user data.

“If you want to attack iPhones, you have to be able to run code to do whatever it is you want to do. Maybe that is grabbing credentials, maybe it is listening into phone calls, maybe it is turning on the microphone. Who knows? But this all requires that you be able to run code” Charles Miller

Unlike jailbreaking an iPhone, which usually requires physical access to the handset, this new system will work remotely. Apple’s security software – which was bolstered for the launch of the App Store, to prevent copied or pirated apps from being used – usually prevents such exploits, but Miller and Iozzo found several loopholes.

The attack will be demonstrated at the Black Hat Conference in Las Vegas next month. At present it works with iPhone OS 2.0, which is the version Miller and Iozzo developed it on; they’re unclear whether Apple will have addressed the exploit in iPhone OS 3.0, which is set for release on June 17th.

Hacking the Pre isn’t just about running Doom on the smartphone: it also promises to unlock currently forbidden functionality such as tethering. The Pre Dev Wiki had been one such team working on that, but after a “polite” warning from Palm themselves have ceased publicly discussing it: it seems Palm is concerned, not that webOS might be modified, but that Sprint may demand the manufacturer step in and prevent users overstepping their contracts.
Sprint do not currently offer a tethering option for the Pre, and as such attempting to use it as an external 3G modem for a laptop or other device would contravene a subscriber’s contract. If that happened, Palm obviously expect the carrier to turn up on their doorstep looking for the hackers responsible to be curtailed, something Palm doesn’t seem particularly concerned about doing themselves.

Of course, we’ve already seen one hack of the Sprint CDMA Pre which bypassed the carrier’s activation and turned it into a WiFi-only device. That can’t be something Sprint would find particularly appealing either, especially if it’s as easy as reported. This seems a fine line for Palm to be walking: they seem to recognize that supporting – or at least not hindering – fan community tinkering can in fact boost the profile and appeal of a new platform, as happened with the original iPhone, but they of course have to keep on the good side of their carrier partners.

Palm’s “webOS Reset Doctor”, the tool intended to be used to reflash broken or bricked Palm Pre handsets, has leaked, and with it the full webOS ROM. Intended only for internal use, the ROM has already been cracked over in the PreCentral forums, and it’s throwing up not only some interesting tidbits about Palm’s intentions for the Pre but about the rumored Eos second device said to be launching later this year.

Mention has been found in the code of both “castle”, assumed to be the Pre’s internal codename, and “pixie”, which has previously been tipped as the codename for the Eos. Palm have never hidden the fact that the Pre is to be the first device of many to use webOS, but the presence of “pixie” in this first-gen code does seem to suggest that the handset is set to arrive sooner rather than later.

Elsewhere in the ROM, icons for MSN and AOL have been unearthed, together with a Java Virtual Machine. There are also plenty of comments left by webOS’ developers, including the somewhat worrying “# what the hell does this do?”

It was arguably the unofficial developer community that accelerated the original iPhone to success: while Apple were attempting to corral programmers into creating simple webapps, those with access to the hacked (aka jailbroken) core of the iPhone could use the same functionality that Apple’s own apps did. Might this be the turning point for the Pre, too?
