Here’s a 2-channel Oscilloscope for your Android phone. It uses a base module driven by a dsPIC for signal processing. From there, an LMX9838 Bluetooth module broadcasts the data to the phone so that the waveform can be displayed. [Yus] ported some Python code he had been using over to a set of Java and XML files in order to get it working on Android. This was actually the first time he worked with the SDK… we’d say he’s a quick learner. See it in action after the break.
Processsing has come to Android. [Jer] posted a guide to setting up the software and coding your first Processing app for Android. The module which supports Google’s mobile operating system is not yet part of the stable Processing release but it works and is available to download and use. It provides support for Android version 2.1 and newer, playing nicely with the SDK to emulate your sketches during development. The Hello World app seen above uses just a few lines of code to draw a white box on an orange background. After you’ve installed and tested the tools you’ll be developing in no time.
This makes a great addition to your Android development tool bag.

The Insignia Infocast is a $169 simple media device being sold at Best Buy. Marketed as a way to share photos and run Chumby apps, hackers are starting to release packages to extend its features. [Bunnie] shows us one package in particular that allows it to be used as a web browser with an external keyboard. With an 800Mhz processor, an 800×600 touch screen, and 2 GB of memory, we can see that this is just scratching the surface of what is possible. [Bunnie] points out that some people are working on porting Android to the device, and if you really feel adventurous, you can dig into the hardware.
[Ewan Hemingway] tipped us off about his new Android app, Androidome. This is the first one he’s turned out after going through our Android development tutorials. It combines an app running on his Android 2.1 device with a computer running Max/MSP 5. The two don’t needed to be tethered, they just need to be on the same wireless network. This won’t be the best solution if you’re doing live performances, as the buttons on the screen end up being quite small. But as you can see after the break, it’s a great way to get into working with the Monome interface and decide if you want to build a dedicated physical version of the tool.
In this tutorial we are going to cover completing the Information Tracker using DroidDraw to design the layout of this project. This will give you insight into an alternative to the stock layout manager in the eclipse environment and how DroidDraw functions. DroidDraw can be your best friend when designing Android applications or your worse enemy if you don’t know the layout of the application and how it works. This will show you the basics to this program and how to incorporate it into your development process. This is significantly easier than the previous post but will teach skills on other programs to help development such as DroidDraw.

Here’s an Android device controlling a LEGO Mindstorms robot. [Josh] and a couple of his colleagues developed software to get both Android 2.1 (video above) and Android 1.6 (video) to work as Bluetooth control devices. The NXT cube is running leJOS, a Java virtual machine, allowing you to program Mindstorms using Java. Although their code is at an early Alpha stage, this shows that it works and is a very welcomed tool for NXT development once they get to a more stable point and release it to the masses.
