Halloween: Season for Java Embedded Internet of Spooky Things (IoST) (Part 5)

So, here's the finished product. I have 8 networked Raspberry Pi devices strategically placed around our Oracle Santa Clara Building 21 office. I attached a JFET transistor based EMF sensor on each device to capture any strange fluctuations in the electromagnetic field (which supposedly, paranormal spirits can change as they pass by).

And, I have have a Web app (embedded in this page) which can take the readings and show a graphical display in real-time. As you can see, all the Raspberry Pi devices are blinking away green, indicating they are all operational and all sensors are working correctly. But, I don't see anything... Darn...

Maybe, I have to stare at the Web app for a while. I don't know when the "alleged" ghosts in our Oracle Santa Clara office are supposed to be active, but let me know if you see anything...

Oh, and by the way, Happy Halloween from the Internet of Spooky Things!
