Keyboard concept uses magic trackpad

This is a keyboard alternative that [Sebastian] is building from two Apple Magic Trackpads. The multitouch devices are a good platform for this because they’re designed to pick up several events at the same time. To prototype the locations of the keys he’s using printable transparency sheets. He gives you a sense of where the home row is with a dab of clear fingernail polish that you can feel with your digits.

He may laser etch these pads once the key location is just right. This should give a bit of texture in itself and do away with the need for nail polish but we still like the ingenuity of that solution. The device is being developed in Linux, with some kernel hacking to handle the devices. We asked about source code and [Sebastian] is hesitant to post it because he’s been getting a lot of kernel panics. It sounds like once he cleans things up a bit he’ll share his work.

Don’t forget, there’s an easy hack to do away with the batteries in these things.

Adding RAM to the Nexus One without soldering

Want 21 megabytes more ram in your Nexus One? [Coolbho3000] worked out a way to tweak the kernel and remap memory usage to free up some resources. That means this comes as a custom kernel image requiring no hardware alteration. Try it out and share your experiences in the comments. But if you don’t need more ram you can just upgrade to the most recent kernel.

Running bleeding edge on Nexus One

We like to run the newest software available. We often encounter problems and things that don’t work because of this, but with open source that just give you the opportunity to contribute and make the package better. Now you can take the fun and daring of bleeding edge to your phone by installing the latest Linux kernel on the Nexus One. [Jon Lech Johansen] wrote up that eight step process to install 2.6.32, which should take you just minutes if you already have the Android SDK installed. If you don’t what are you waiting for?

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.

KernelCheck kernel compiler

kernelcheck

If you’ve ever tried compile a linux kernel yourself you know the headache of configuring and taking care of dependencies. KernelCheck makes this a point and click process for debian based linux distributions such as Ubuntu. You can use it to compile and install any 2.6.* stable kernel as well as the bleeding edge. KernelCheck even offers custom compilation options such as including kernel patches or rolling in proprietary video drivers. A tutorial (PDF) is also provided so you can see what you’re getting yourself into.

iPod Touch 2G jailbreak demoed

redsn0w

Now that the iphone-dev team has unlocked the iPhone 3G they’re moving onto jailbreaking the iPod Touch 2G. While they have a fully working jailbreak, it’s not yet in a user friendly format. [MuscleNerd] did a live video demo this afternoon to show what progress they had made. It starts with him showing the iPod on but not booting. He’s already patched the kernel, but it’s failing the signature check in iboot. He then uses the team’s recoverytool to exploit a hole in iboot and patch out the signature check. The ipod then boots normally and he shows non-App Store software like Mobile Terminal, Cydia, and an NES Emulator (which makes use of the iPod’s internal speaker).

The redsn0w jailbreak works, but it has to be applied via tether every time the iPod boots. The team won’t release anything until they’ve found a way around this problem. For more insight into the boot process, check out our coverage of their Hacking the iPhone talk at 25C3.

Android adds A2DP, AVRCP Bluetooth and more

tmobileg1

While working towards open-sourcing Android, the team continued to work on new features in their own private development branch. These have now been published publicly in the “cupcake” branch. There’s a lot of interesting new features and bug fixes included. We’ve got a rundown of many of the significant additions after the break.
