Everyone is making tablets and everyday we have more to choose from. Now Japanese-based company Redstar has begun pre-orders on their own Shogo Linux-powered tablet. The 10.1-inch tablet will be powered by a Freescale iMX-37 processor, with a 1024 × 600 resolution and multi-touch capability.

Some other features include 4GB of internal memory, Wi-Fi and Bluetooth, 3G support, Zigbee, an SDHC memory card slot and 256MB RAM. Who knows if we will see this one in the States.

Dell has made a promise to open source its Streak code. Dell’s official blogger Lionel Menchaca says that Dell will meet “all applicable requirements” in due time. The version of Android 1.6 used by Dell is based on a Linux kernel and fits under the GNU Public License (GPL), which requires that it open-source any new code.

Without Dell’s custom portions of software, programmers haven’t had access to the drivers and other code that speaks to the Streak’s hardware. There is no deadline for when code must be published, but it’s usually assumed code will be available immediately or shortly before any hardware or software ships.

Symbian, the world’s most popular smartphone operating system, has announced that it’s going open source about four months ahead of schedule. This move will allow more software developers to have access to develop applications and mobile devices based on the operating system.

The plan was to complete the transition of putting the OS under the Eclipse development license and work out deals with existing third party developers by later this summer. Symbian was able to move ahead more quickly, most likely to try and keep an edge on the newer open-source Android mobile operating system from Google.

Jeff Bezos wants the Kindle to have some healthy competition. That’s why Amazon just released their source code for all the Kindle devices. It’s basic Linux underneath (kernel 2.6.22 on the latest 2.1 software), but includes E Ink drivers and other hardware support.

We don’t know whether Amazon stripped out its various DRM and licensed codec support, MP3 and Audible seem very likely candidates for explosion, even if turns out Amazon did leave in its own Kindle Book DRM. Hopefully manufacturers can take and repurpose this code to build their own Kindle clone.

Gameboys are cheap these days. You remember Gameboy. That monochrome handheld with the sort of greenish urine colored background. You can get one for about $20. But why not make your own? Some guy named Matt decided to build an “open source Gameboy” called Gamepack, using off-the-shelf parts, including an Arduino microprocessor. The Arduino providse the brains, while the 128×128 TouchShield Stealth color OLED touchscreen takes care of the rest. An Inputshield board provides a tiny joystick that even sports rumble, with control buttons and a flat Lithium battery pack.

Lucky for you the Gamepack system is available in kit form so you can build one yourself. Thing is, at the moment, the Gamepack only runs some rudimentary homebrew demo code, but the idea is that others will contribute more advanced games, or maybe even a Nintendo emulator. It’s steep at $249, but a pretty cool project.
