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.
