Aural Twitter

[POTUSCamacho] listens to his @public_timeline rss feed. In part one of his project, he describes creating a bash script in which he uses cURL get his private feed, sed to clean it and eSpeak to output a WAV file. In parts two and three, he goes on to discuss how he created an audio stream (currently down, opens in a new window) of @public_timeline and how he plans on tweeting vocally.

New AVR Simulator For Linux

simavr is a software simulator for the AVR line of microcontrollers. You might be asking why anyone would write this sort of thing considering the simulator provided with AVR Studio is a wonderful tool? Well, a lot of folks don’t run Windows and don’t wish to use that development environment even if Wine or Virtualbox could make it happen.

We haven’t tried it out ourselves yet. There is a discussion thread going that reports some positive results of using simavr with GDB and AVR Eclipse. It’s a new package, but so far it seems to have put its best foot forward. Currently there is support for ATtiny25/45/85, ATtiny13, ATmega48/88/168, andATmega164/324/644 chips. Several of the common on-chip peripherals are already supported with the others on the way.

Have you tried it out? Let us know what you think in the comments.

How To Use Wiimotes W/ Linux

[Sprite_tm] has whipped up yet another interesting tutorial – software-based this time. He basically describes how he connected his Wiimotes to an HTPC. A USB Bluetooth receiver, and a little bit of Linux scripting,  was all that was necessary to get the system up and running. To add to the fun, [Sprite_tm] configured a the controllers to work with MAME (an arcade machine emulator), allowing one to play Duck Hunt on a computer in its full glory!

Color Correction Patch For PS3 Eye

ps3-eye-color-correction

[Max] was happy to see that the PlayStation 3 Eye has support in the newer Linux kernels. Having sat in his closet for quite some time, this would give the camera another chance at usefulness. Unfortunately, the driver doesn’t include framerate selection and color correction so he set about writing a patch to control the color settings. As you can see above, his success greatly improves the image quality you get from the device.

We get the feeling that the camera peripherals for Sony’s gaming devices seem like a good idea but don’t have much staying power as a realistic gaming interface. With contributions like [Max’s], they can be re-purposed. The PS2 had its own, the EyeToy, which has long enjoyed driver support for Linux. The NUI Group does a lot of work with multi-touch and recommends the PS3 Eye for use with their projects because they’re inexpensive with high frame rates and decent picture quality.

Great work [Max]. It looks like he’s sent this patch upstream to be considered for incorporation into the kernel’s webcam module.

Ubuntu 9.10 Karmic Koala

ubuntu-karmic-koala-splash

Today is the official release of the latest version of Ubuntu, the most popular Linux-based operating system. Someone mentioned that there had been a new release of the Windows OS recently and if you’re thinking of going with that one, we feel you should a least give Ubuntu a try. Now in its 11th official release and codenamed Karmic Koala, this version of Ubuntu continues the traditional six month development cycle by succeeding Jaunty Jackalope which was released in April of this year.

We’ve been running the beta release of Ubuntu Netbook Remix for several weeks now. It cut boot time down to between 5-10 seconds and WiFi is already connected by the time the Desktop loads. Speed isn’t the only new feature, graphics have been redesigned, there is a new app store that serves as a front end for the extensive free software repositories, and the newest kernel and software versions are included.

We’ve been using this open source operating system since its third release, Breezy Badger. We love it for the quality, convenience, and the fact that we can get our fingers into the code and hack around a bit.

Linux IPhone Sync Draws Near

linux-iphone-sync-support

[Emuboy] lets us know about some software advances that will make iPhone and iPod Touch syncing possible under Linux. Apple made big changes to how the iPhone syncs compared to legacy iPods. Locking out all communications other than through iTunes was surely part of their motivation. This has left Linux users out in the cold with shoddy sync capabilities which should be coming to an end. If successful, syncing will be be possible with phones that have not been jailbroken.

One of the biggest hurdles in reverse-engineering the new protocol is the non-standard way in which the devices communicate over USB. The usbmuxd developers have been working to implement communications and now have a Release Candidate for the 1.0.0 version. Along with testing of this package, libgpod is now being updated to play nicely with the new database format and hash of the iPhone.

This isn’t quite at the plug-and-play level of convenience yet but if you’re comfortable working with Linux packages you should be able to get this working and help report any bugs you might find. But if you’re tired of open source playing cat and mouse with Apple you can always switch over to a device based on Android.

Head-mounted Computer With Linux, WiFi

hmdlinux

Most wearable computers we’ve seen feature a head-mounted display tethered to a small PC system in a backpack or worn on a belt. Here’s a slick little system that does away with the cord, fitting the entire system in the glasses.

[Pascal Brisset’s] WXHMD is based on the tiny Gumstix Overo Fire computer-on-module which features a beefy, 3D-capable OMAP processor that runs Linux. The Gumstix is interfaced with a Vuzix VR920 head-mounted display that includes a three-axis accelerometer and compass. Tying these together is a custom video digital-to-analog converter board of [Pascal’s] own design, created using direct-to-PCB inkjet printing techniques. For less than $1,000 total in parts, the result is a spatially aware six ounce computer, with display and battery and all, that fits neatly over the bridge of one’s nose.

It’s a fantastic hack and a nicely documented project, though even the device’s creator himself questions whether having a pair of microwave transceivers and a LiPo battery strapped directly over one’s eyes and brain is such a good idea.
