The device which you can see in the above picture us an Android Bluetooth Oscilloscope. Its base module driven by a Digital signal Controller for signal processing. When the signal is processed, a module named LMX9838 broadcasts the data to the phone so a waveform is displayed on the deivce. When you port Python code used over a set of Java and XML files you can get the device to run on Android. As you can see in the picture and the video below, you can find a waveform visual stimulation.
Now you can just simulate your circuit if you have a set of A-D converter, dsPIC and a bluetooth.
It was too painful on my side, because I had to convert a single script file to multiple java + xml source files! Nonetheless, it was a good experience for me on learning the Android SDK (JAVA programming).
