How do i build an aura imaging device?

Measuring input from points on a persons hand with passive electrodes you can create an image allegedly resembling the persons aura. How would i go about bulding such a device possibly utilizing a arduino microcontroller?

Hi, I'm researching this exact thing for my MRes project, dm.ncl.ac.uk/davysmith/blog I have some references, but am looking for programming solutions at the moment. Have managed a basic example through GSR though. Hope it might help Davy

By realizing that "auras" are not real, saving yourself quite a lot of time and move on. Either that or build a galvometer, name the aura-meter, give people a-ratings the start a cult.
Priceless! My thoughts exactly :-)

About 25 years ago, I used to own a Kirlian photography box. Before the digital age, the aura was recorded on photography paper in a dark room with only red light, and had to be developed. It said there was a Tesla transformer inside it. Eventually, it got fried. I had a total lack of electronic understanding at the time, and it got thrown out.
A fellow named Guy Coggins came up with the original Polaroid-based "aura photography" system back in the 1970's; he later updated it to use a camcorder and then a webcam. You can see this at http://www.aura.net/ - the system costs something like US$12,000.  I saw one in action at a psychic fair in Ottawa, Ontario about 4 years ago, charging $35 for an 8 1/2 x 11 dye-sub photo and 12-page printout. The software is called WinAura - see EBay item #150331054226 for more info.

Basically it uses a hand-plate with a bunch of metal contacts to measure skin resistance between multiple points; you can find plans for something similar at http://affect.media.mit.edu/projectpages/handwave/
(open source, PIC driving it, connects wirelessly via Bluetooth; probably not too hard to adapt for Arduino instead; they have some papers about using it for various biofeedback tasks - one about predicting when the user is going to hit a button, up to two seconds before they are conscious of it ;-)

It then uses this data to 'fake in' an aura over your photo and generate a bunch of boilerplate blah-blah about your psychoemotional resonances.

There have been some scientific tests on the existence of auras actually.  Sorry to say they didn't really find any evidence.  I guess from here you could a) work on proving the existence of auras or b) measure something else.  I'd go with b, and I have something in mind for you already -- an arduino with a capacitive sensor.  I made one the other day and was surprised how well it worked.  Just need arduino, resistors, foil, and plastic wrap.  The sensor measures changes in capacitance and through this it can measure if your body/hand gets near it and how close.  Maybe different people will give different signals and it could be like an aura.  You could then just read the output from a screen if you want, but I'd make it change the brightness or color of an LED.  You could even have it play a tone that changes when you move your hand near it.  Here's the link for the writeup on arduino.cc: www.arduino.cc/playground/Main/CapSense

ask an expert on the subject? if there even is such a person i dont know where to find one

It sounds like capacitance to me.
