CNC Engraver Upgrades

November 21, 2008 by 3 Comments

We’ve been following [glaciawanderer]’s CNC build for quite some time and he’s recently added a few upgrades to make for an even more interesting machine. He’s been trying out new bearing blocks, anti-backlash nuts, and z-axis plates hoping to get some improvements. In the case of the bearing blocks, he went back to the older style because of the added safety and smoother movement. The final addition he made was a dust collection system. It’s just a couple support hoops and duct tape, but it should keep dust out of the threads and rails.

YouTube Testing Even Higher Quality Videos

YouTube, purveyor of some of worst looking flash video is finally getting their act together. We posted the other day about embedding videos using &fmt=18 to get higher quality YouTube videos. It seems the awesome knob has now been turned up to &fmt=22. All of the previous tricks should work, just use 22 instead of 18. This all depends on the highdef version being available. Now they just need to get rid of the grainy preview images.

Faster Browsing With RAM Disks

A coworker approached us today wondering if they could get a performance boost using Samsung’s newly announced 256GB SSD. Most of their work is done in browser, so we said “no”. They’d only see benefit if they were reading/writing large files. Their system has plenty of RAM, and we decided to take a different approach. By creating a filesystem in RAM, you can read and write files much faster than on a typical hard drive. We decided to put the browser’s file cache into RAM.

PSP 3000 Hacked

November 19, 2008 by 63 Comments

Peripheral manufacturer Datel has been hard at work attempting to crack the PSP 3000 since its release. They’ve developed the Lite Blue Tool battery to force the PSP into service mode so hackers can run any arbitrary code they want. According to MaxConsole, Datel performed a silicon level investigation of the PSP’s chips to determine how to break into service mode. This means they decapsulated the the chips and reverse engineered any cryptographic protections. We’d love to hear exactly what chips were being used since some are fundamentally flawed.

Silicon hacking has always been a favorite topic of ours and we suggest you check out [Chris Tarnovsky]’s decapsulation technique to learn more about it.

Iphone-dev Team 3G Soft Unlock Coming Soon

The iphone-dev team has officially stated “all that remains is implementation“. They’ve developed all the pieces they need to perform a software unlock for the iPhone 3G, now it’s just a matter of putting them together in user friendly fashion. They’ve managed to run unsigned code on the baseband, developed custom AT tools, and are now showing injection of a background task. They will combine all of these techniques to override the carrier lock baseband code. As usual, they warn against performing any official firmware updates to the phone.

Augmented Reality In Flash

November 19, 2008 by 35 Comments

Digital Pictures Interactive has put together a great augmented reality demo. Unlike many others, it’s entirely Flash based, so there’s no install necessary. Print out the custom symbol and try it out for yourself in your browser. Augmented reality refers to any mashup that combines computer generated content with a live video stream. We see great potential for this technology and the large number of consumer webcams would certainly help consumer adoption. Video demo embedded below. Continue reading “Augmented Reality In Flash” →
