Here is a new video of the modifications done by Mr Aniket Kandalkar to V3.

The main mods are:

• Base for holding all things together, including the yellow plywood, PVC pipe holders, leveling screws.
• Electronics box, which includes the mouse circuit, the Arduino Uno, and PCB.
• The PCB, hand soldered as of now, has some LEDs to indicate the activity of the device, useful especially when data is being logged but not plotted on the computer. (the mouse has a tendency to sleep off).

The next idea will be to program the Arduino to log data onto an SD card every 10ms, for many days and then to eventually do some data analysis to see if we see a daily seismic trend.
