Android and Chrome OS are merging - a new Desktop OS will soon be here!

It's official! Android and Chrome OS, two operating systems made by Google, are merging.

What I have understood Chrome OS won't be there anymore but will be replaced with Android. Not 100 % sure though...

The new Desktop OS will be called Android and will be running on PC hardware. I guess Google wants to challenge Microsoft and it's operating systems Windows 7/8.1 and 10.

You have to wait until 2017. However, it's not that far away, is it!

Me and my Chromebook really look forward to see the new Android!

Edit: Android and Chrome OS might NOT merge? Not sure who to believe anymore.

How to make Lilypad blink an LED

Every time you start a new project with your Lilypad or Arduino make sure your hardware works. This is done by running "Hello world" -app.

Open your Arduino IDE (see picture below). If you don't have Arduino IDE, get it here: In case you are running Linux you might need extra elevation of rights (i.e. sudo su in Ubuntu) . Attach USB cable and Lilypad to your PC. Under Tools in Arduino IDE, you can check if the right Arduino/Lilypad model and port are chosen. Many times it happens your hardware seems not work. This is due to wrong hardware and port.

In Arduino IDE click File, Examples, Basics, Blink. Right after that, Save Blink somewhere else. Now, change the code. For example, reduce the blinking time from 1000 ms to 100 ms (see picture below; delay (1000). Finally, click an arrow which points to the right. It saves, compiles and sends the code over to Lilypad or Arduino. Thumbs up! Fingers crossed! If you are lucky you have your very first Lilypad app up and running!

An AOSP version of Android 6 is now running on my Nexus 4

An AOSP version of Android 6 runs on my Nexus 4

Google didn't publish Android 6 upgrade for Nexus 4 in the beginning of October 2015. My bad. However, only a week later the first AOSP-version* of Android 6 showed up! You can download all files needed here:


Instructions say TWRP 2.8.7 (recovery tool) is needed. My version was older 2.8.6. There is TWRP Manager (root) in Play store. Thus it's easy to download and install the latest version of TWRP on your phone. See here: I guess Nexus 4 needs to be rooted in order to make TWRP Manager work. You have to find out how to root Nexus 4 for yourself.

Android 6 and Google apps

I downloaded (= Android 6) and (= Google apps). Using a file manager app it was easy see where inside my Nexus 4 those two zips were. TWRP manager was able to flash both zip-files (first Android 6 and after that Google apps). No help from PC was needed. No USB cables. Nexus 4 only.

First boot

It took some time before Android 6 showed up. First there was no carrier. After reboot I was able to make phone calls. So now I have Android 6 up and running! Look at the pic below.

*AOSP = Android Open Source Project (= Google leaded project for Android)
