Digikey sort by price script

Does anyone else find it a little ironic the electronic retailer SparkFun is advocating scripts to help Digikey have a Sort By Price function? Regardless, to reiterate now Firefox (and we hear Google Chrome too) users with the Greasemonkey plugin can sort Digikey items. Personally, some of us here are just Mouser fans at heart.

Maze solving

[Mitchel Humpherys] and his fellow developers didn’t just develop a maze-solving algorithm, they also built a ping-pong ball maze platform that is computer controlled. Using a webcam the computer picks up the high-contrast maze by peering down from above, calculates the solution, and moves the ping-pong ball to the goal using two different tilt servos controlled by an 8051 microcontroller. But wait, there’s more! Why have the computer solve it when you can make a game out of a maze? Once the PC was thrown into the mix it was pretty easy to add Wii remote and Wii balance board control too. See these alternative inputs in action after the break.

PS3 patch allows Linux installation

[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?

[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

[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.
