Here's an interesting experiment that lets you simulate PenTile displays on a normal LCD monitor. [Barrett Blackwood] wanted to test out how some graphics look on PenTile RGBG displays with different pixel densities. These PenTile RGBG matrices are sometimes used in OLED displays. For instance, the Nexus One smart phone features a display of this type. Because red, green, and blue OLEDs emit … [Read more...]
Here's a look at the TRRS cable that Android phones use. [Rich Kappmeier] want to control the music player on his Nexus One while driving.

[Pikipirs] developed an app that lets you connect a Wii remote to an Android phone. After the break you can see it used with a Sega emulator. The button presses seem very responsive, making for a nice gaming addition if you care to carry around the Wiimote in addition to your phone. It certainly seems to work better than the Wii remote + iPhone hacks we've seen. Pick it up from the Android store … [Read more...]
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. [Thanks Juan] … [Read more...]

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 … [Read more...]
