You might not be familiar with an oscilloscope, but it’s a device that can display visual images of varying electrical voltages over time. Now the Android oscilloscope Bluetooth project is a device that can be hooked up to an Android device via Bluetooth, creating a cheap, portable device for processing electronic test measurements on the go. It captures two channels of data at 2MHz/sec using a PIC microcontroller that converts the analog signals to digital signals. In case you’re handy with your programming skills and are comfortable working with the Android SDK, the author has included his source code online for you to recreate this setup.

Android: Android is the mobile operating system from Google. The software was originally built by a company called Android Inc, that was purchased by Google in 2005. From its modest debuts, Android has become a powerhouse that powers not only smartphones and tablet, but a host of other less high-profile devices and gadgets. Although Android is not a community-driven project, Google does release the source code as open-source under the Apache license. You can follow Ubergizmo on Android with Google Currents.
