This week in class we were focused on the ethics assignments. Outside of class I worked on microphone testing with our adafruit SPW2430. The preliminary testing is hopeful, but I was unable to get a working soldering machine, so the connection is not very accurate, so hopefully after soldering we will get even better results. The microcontrollers and raspberry pi have been registered with the cmu wifi, but we are still working out some connection issues. This step is necessary before we try to combine the two types of data. The tests were run with an arduino in order to have an analog port to test with. The wifi microcontroller have analog ports, but for inital testing it is not necessary to run it over wifi. 
This is an example of the results from one of the tests:
The tests account for the DC voltage bias. We had hope to be connected our different sensor data this week, but we are not too far off from our expected timeline.
