Send frequency data to the diamond polishing operator's computer in order to facilitate future experiments.
Using a microphone, send the diamond "noise" (which actually is different frequencies) into the and amplifying circuit, which will be connected to a display, giving the operator real-time frequencies to help monitor the current diamond polishing.
An accelerometer will be placed onto the diamond polishing arm to measure the acceleration/vibrations. If the vibrations are more violent it means the arm is out of balance and an alarm will go off, warning the operator to fix the arm balance.
