PS3 Patch Allows Linux Installation

May 11, 2010 by Mike Szczys 37 Comments

[Geohot] came up with a patch that allows OtherOS on 3.21 PS3 firmware. You’ll remember that Sony released version 3.21 specifically to prohibit OtherOS which allows the installation of Linux for which they were subsequently sued. Well, now their “fix” doesn’t work on people willing to flash patched firmware which means they’re only punishing those who play by the rules. Ugh.

Wondering why this is a big deal? Check out this article on the effect Sony’s move has on PS3 clusters used for supercomputing; something we hadn’t even thought of initially.

It turns out that this patch was released more than a month ago. Sorry for the late coverage but it’s new to us. You can see the obligatory proof video of the patched OtherOS after the break.

Original NES Plays Game Boy Games?

May 11, 2010 by Mike Szczys 26 Comments

[Bunnyboy] pulled off some wizardry with this custom NES cartridge. Inside is the mainboard for a Game Boy as well as his own custom PCB with the comb connector needed to interface with an original Nintendo Entertainment System. In his own words it’s “a Super Game Boy without the Super”. The expansion port to for the handheld is still accessible for some head-to-head Tetris or use with the obscure Game Boy printer.

Open3DP Looks At 3D Printing In Common Materials

May 11, 2010 by Mike Szczys 11 Comments

[Buddy Smith] sent us a link to Open3DP which he calls “REAL 3d printing hacks”. Open3DP showcases the projects of the Solheim Rapid Prototyping Laboratory at the University of Washington. They’re working on 3D printing in materials that can be commonly acquired and to that end they publish recipes for powder printing in materials such as sugar, ceramic, and glass. Take a look through their archives. We found the post on microwave kilns interesting, as well as the writeup about Shapeways glass printing which is seen above. We’ve also embedded a short video on Open3DP’s work after the break.

Update: [Mark Ganter] dropped us a line to clarify that Open3DP was the first to develop printable glass about a year ago, called Vitraglyphic. They’ll also be presenting papers at Rapid2010 and announcing a new printable material.

Hack Your Crystal’s Frequency

May 10, 2010 by Devlin Thyne 53 Comments

[Drone] tipped us off about [Joachim]’s efforts to alter a crystal’s frequency. Through a process called penning, a crystal’s resonant frequency is lowered by painting the crystal with an indelible ink marker. Our curiosity piqued, we went off and found more information about penning crystals. It turns out this technique has been around for nearly as long as there have been amateur radio operators. Outside of your local oscillator, and radio jammer, how might you best use a hacked crystal?

Color A Sound

This is an interesting take on a music box. [Blair Neal] is using an overhead projector with a roll of transparency to make a synthesized music box. A camera watches the projected image and feeds data to Max/MSP to produce the sounds. Customization merely requires creative image analysis. In this case, different colored pens or different tracks can be assigned to a sound with the speed of the track based on how fast you wind the transparency spool.

More Glove-based Interfaces

You may remember seeing the golf glove air guitar hack last month. Here’s two more uses for gloves with sensors on them.

On the left is a glove interface with flex sensors on each digit as well as an accelerometer. The VEX module reads the sensors to detect sign language as a command set. A shake of the hand is picked up by an accelerometer to delineate between different command sets. See it controlling a little robot after the break. This comes from [Amnon Demri] who was also involved in the EMG prosthesis.

Straight out of Cornell we have the SudoGlove, seen on the right. [Jeremy Blum] and his fellow engineering students bring together a mess of different sensors, sourcing an Arduino and a XBee module to control a small RC car with added lights and a siren. There’s embedded video after the break. You may want to jump past the music video for the description that starts at about 3:52.

FPS Controller Hacks Getting Easier

May 10, 2010 by Mike Szczys 12 Comments

It used to be a major production to build a gun-form-factor FPS controller but commercial tech has adopted many of those traditional hacks over the years. Now, [Nirav Patel] is playing Cube with a Wii zapper and a SpacePoint. All that was really required to make this happen is a patch to Cube, the open source FPS.

[Nirav] has plans to make this controller wireless using a BeagleBoard. We’re wondering if there’s support for using the Wii motion plus? We’ve seen motion plus Arduino connectivity, as well as direct PC connectivity. The Wii remote already connects to Linux, what about pulling that data down from the Bluetooth connection? If you’ve done this, send us a tip about it.
