The SW-420 Vibration Sensor will detect large disturbances and send the data to the Arduino. The occurrence and strength (Intensity) of the vibrations will be displayed on an LCD screen.

While there are a couple of open-source brushless drivers already available, [neuromancer2701] created his own brushless motor controller on an Arduino shield.

[Lee] took off the vibration motor and used it as an output port for a simple program to dump the ROM. An Arduino picked up the data at a low baud rate and produced an output file.
