Apart from electronics, one of my other interests is the paranormal. I used to be the worlds biggest skeptic on the subject until I experienced a paranormal event myself, so now I'm convinced there's something to it. Anyway, the project is to design and build a standalone piece of equipment that you leave it overnight and then retrieve it the next day.
The heart of the system will be a Arduino Duo, which will detect any fluctuations in - sound, visible light, infra-red, vibration, EMF, static, and any other source of energy, which would then trigger video and sound recording.
I decided on the Arduino as I'm not that good at programming and the Arduino is as simple as you can get. So If anyone else is interested in this adaptation of electronics I'd be pleased to hear from you and will update on the project as it progresses.

I am myself somewhat skeptical about possibilities to detect those so-called paranormal events using electronics and sensors, However, I believe that cyber_drifter is not doing anything wrong with his project: As while science is all the time advancing, there are always some hard-to-explain things in the world. Curiosity in areas not yet known and understood has always been a driver for scientific research!

If we call those "paranormal" or whatever else, the idea for me sounds to be trying to capture information in an "open" way. I can't predict the results, and hardly anybody else can do it here. In worst case we can learn a bit more about different sensor solutions, in best case we might detect something "weird" to research further.

Therefore, I would rather that we discuss here what kind of platform and sensors could be used for such data capturing attempt.

My ideas in this context are quite a few in areas of sensor construction. In addition to the obvious such as sound, light and temperature, I believe one can construct with relative ease detectors of relative magnetic field gradients and detect electrical fields. My largest questions are in the area of Arduino's sufficiency for capturing so many data channels, of which some might need significant data storage capacity and some processing power, too.

If you feel comfortable with Arduino environment, and want to use some of many "shields" available to interface with sensors, a more powerful processor might be for example a 32-bit PIC -based Pinguino MX220. Olimex sells ready-assembled boards for EUR 9.90, so that would not cost more than an Arduino board, but have much more capabilities. However, you might prefer, due to data logging storage needs, its big brother PIC32-PINGUINO-OTG, with a price tag of EUR 21.95: It has also a micro-SD connector for a memory card.

I have personally never used the development environment for the Pinguino family, but what I read it is quite similar to the Arduino's tools.

Also, for longer-term monitoring a low-power operation might be useful, so that even a smallish battery would last overnight. That PIC processor is in power consumption terms not bad at all!

I saw an article about detecting people using RF fields. That could maybe serve as one of detectors:
http://cocoontech.com/forums/blog/12/entry-97-electric-field-proximity-sensor/
I believe the detector would react on conductive objects/bodies, or maybe also dielectric ones (er>>1).

Another relevant detection technique might be an electrical charge detector / electrometer, such as in http://amasci.com/emotor/chargdet.html For interfacing into a micro-controller, one should connect a resistor in series with the JFET and feed the resulting voltage to a port having an A/D converter.

In a book that i read the author was using  dowsing rods to detect and map  some strange kind of Earth energy lines across Scotland ( they exist all over the world). He also detected paranormal activities in houses and he concluded  that these were related to Earth energies.He stated that with some practice everyone could use dowsing rods and also said that he could "tune" him self for what he is searching: water, petrol , Earth energies ( i suppose more reading on the topic is required to achieve that)  .
May be if  some angle sensors are attached at the tips of the rods , places with anomalies could be found.

cyber_drifter:

I'm not trying to talk you out of anything. Who knows what you will find? But I do know this: My niece (my brother's daughter) spent a *ton* of money on this "equipment" like an "EMF Detector" which was basically a crystal radio (diode, small coil and a couple caps) connected to an LED bar driver. She also had a "Paranormal Recorder" for communication with the dead. This was also a crystal radio connected to a micro that dumped audio to an SD card. The demodulated audio was so low that on playback I couldn't tell if it was Albert Einstein giving me the Unified Field Theory or a commercial for a car dealership. I *do* know a 2 meter HT connected to a dummy load caused the "EMF Detector" to show a *lot* of spooks around. Anyway, good luck. Let us know what you find.

Before I forget, some older digital cameras had an IR filter on the front that could be removed (so the camera saw in the IR range). There used to be some videos on Youtube of people that had done this and saw some really peculiar things.

I had some paranormal experiences over the past 5 years after some family members died.  I've seen orbs in digital photos which could be particulate matter illuminated by a flash though there was at least one case where a green orb was present when the flash was not used.   I've had orbs in surveillance video, taken with IR illumination.  I've investigated using a variety of instruments including spectrum analyzers and thermal imaging gear, but did not find anything conclusive.

One of the most interesting phenomena I observed was CMOS (4013) flip flops changing states by themselves.  I have 2 radio shack digital dice devices, one of which I assembled in the 1970s.  I obtained the 2nd unit a few years ago from ebay after observing the state changes on the unit I put together.  These devices are powered by a 9V battery which is sufficient to retain the last state for years because of the very low leakage current of the CMOS chips.  In the over 3 decades this device was powered and sat on a bookshelf, I had never seen it change state by itself and had never seen it display an invalid state (a state not defined by the finite state machine design).  I had this device change state 4 times in 2014, each time with the left die blank and one time with a "7" (invalid state) in the right die.  My father had a severe hemorrhagic stroke and passed about 2 months after the last incident.  The other digital dice unit I obtained from ebay has had one unexplained state change (from a 1 x 1 to 3 x 1) in 2015.  Both units except for the unexplained state changes function normally.  

It would be interesting to construct a device with a number of 4013 flip flops and to continuously monitor their states for change.  

I also came across some interesting paranormal video:

PS.  In many digital cameras, the IR filter can be removed and replaced with developed unexposed slide film to make the sensor only sensitive to IR

Maybe you can find something useful in the book "Electronic projects from the next dimension: paranormal experiments for hobbyists", by Newton C. Braga.
I've found only the russian version of this book. You can find the link in the E-books and Tutorials section, if you're interested.
Perhaps someone here has the english version?

While I understand the want of people to find another level of existence,  my mind keep telling me that whatever the stipulated result from the "detector" could come from known sources.

Eg. the dice device is always in the brink of a flip or flop state that a small static charge from dry air or even a small radio signal received by the wiring might influence the change of state.

It is also a long time theory of mine that question the "questionable but coherent" radio data received from supposedly obscure location.  Would it be possible for a radio signal being bounced back from nearby location (read natural delay circuit) from such thing as a cave, hollow water pipe or whatever..

Yes I am a skeptic.

I'm a scientist and I suppose to know the scientific method and to distinguish between metaphysics and physics.
I'm (very) skeptic but curious at the same time.
I like People that try to apply a rigorous scientific method also for "exotic" things with a honest approach.
If someone knows the chaos theory, the source of "noise" may be perturbed by billions of sources including...butterflies or ghosts.
From few days we know that gravitational waves exist...
... and the new level of reality of Tomorrow?
I agree with Optikon: "The guy doesnt even define white noise properly" but his explanation is not incorrect, understandable and sometimes this is much precious than a rigorous (but unintelligible) definition.

I have once played around with a magnetic field change detector based on Barkhausen effect. The practical arrangement was: A ferromagnetic piece has a coil around it. The induced signal in the coil is amplified with a high gain low noise audio amplifier, and fed to speaker/headphones.

Barkhausen effect: If there is a magnetic field going through the ferromagnetic material, the magnetization is not changing "smoothly", but in tiny steps. The phenomena is due to microscopically tiny magnetic domains turning due to the magnetic field on varying field strengths in a "snap-like" fast action. 

Those steps induce small audio-frequency pulses to the coil, and the system, making audible cracking sounds.

I found out, that this simple detector was pretty sensitive to magnetic field changes, and when biased by a permanent magnet could even detect presence (or more correctly a change in presence) of ferromagnetic objects in considerable distance - for example one meter away. The sensitivity seemed to be dependent quite much on magnetic material used in the detector's core,  and I got pretty good results with pieces of iron sheets from an old mains transformer.

If we assume, that if the "spiritual energy" contains also some magnetic energy, this kind of simple device should be able to detect the resulting field strength changes. Worth trying?

I conducted some experiments using the magnetic field sensors in this device:

http://www.aaronia.com/products/spectrum-analyzers/NF-5030-S-EMC-Spectrum-Analyzer/

It contains 3 coils oriented as X/Y/Z fed to high gain amplifiers.  But, the coils may be too small to provide sufficient sensitivity to detect a small magnet from a meter away though.  I left it continuously logging data for several months and never picked up anything I considered paranormal. 

The most notable paranormal phenomena I observed were (in no particular order):

(1) cmos flip flops changing state by themselves as I described

(2) orbs in surveillance video (in darkness with infrared LED lighting)

(3) peculiar trigger patterns in surveillance video such as motion trigger (without any visible motion) every hour on the hour (to the millisecond) or everyday at specific times like 10am for several weeks

(4) green orb in digital still photo without using flash

(5) electrical box cover falling from ceiling with no one in building, recorded by surveillance video; 2 screws holding the plate somehow had become unscrewed with no apparent damage/defect in the screws, electrical box, or the cover plate

The device you used is not particularly sensitive, as it is intended for EMC pre-compliance measurements. And the field strength limits of interest are relatively high.

The Barkhausen device is especially sensitive to changing nearly-steady-state field, and only detects that there is a change - and doesn't give any change direction information whatsoever. The elegance is its simplicity and compact size (a small iron-core coil is enough).

A high-gain and low-noise pre-amplifier is necessary for detecting the noise pulses. I used a two-stage OpAmp -based circuit with G = 100 x 100 =10000 and fed the output to an ordinary audio headphone-output amplifier.

Unfortunately I didn't immediately find the schematics of my design to attach here. However, a suitable component for design basis is for example Linear Technologies LT6234, which operates from about 3..5V single supply (up to 12V can be used), and has extremely low noise specification even to low frequencies. Thee are other comparable performance (or even slightly lower noise) components available, if the supply can be for example +/- 9V ... +/- 15V. (However, personally I prefer to design low-voltage designs where just 2-3 standard alkaline cells or a single Lithium cell of 3V is a sufficient power source....)
