Now here's the hardware you'll need to make a Java app interface with a static charge sensor connected to your Raspberry Pi via the GPIO port.

It means another Fry's run of course. That's not too bad during Christmas since you can browse all the gadget and toys while doing your shopping for sensor hardware for your RPi.

Here's a your 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

Grab all that from Fry's or your local hobby electronics shop and come back here for how to connect it together. Oh, and don't go too crazy buying all the other electronic toys and gadgets that catch your eye because of the holiday displays at the store.
