Halloween: Season for Java Embedded Internet of Spooky Things (IoST) (Part 2)
- by hinkmond
To start out our ghost hunting here at the Oracle Santa Clara campus office, we first need a ghost sensor. It's pretty easy to build one, since all we need to do is to create a circuit that can detect small fluctuations in the electromagnetic field, just like the fluctuations that ghosts cause when they pass by... Naturally, right?
So, we build a static charge sensor and will use a Java Embedded app to monitor for changes in the sensor value, running analytics using Java technology on a Raspberry Pi. Bob's your uncle, and there you have it: a ghost sensor.

So, go out to Radio Shack and buy up these items:
shopping list:
1 - NTE312 JFET N-channel
transistor
(this is in place of
the MPF-102)
1 - Set of Jumper Wires
1 - LED
1 - 300 ohm resistor
1 - set of header pins
Then, grab a flashlight, your Raspberry Pi, and come back here for more instructions... Don't be afraid... Yet.
