OfflineGEOPHONE
You may have seen a new device used on recent episodes of GH/GHI called a geophone. A geophone is a device that measures seismic vibrations down to 4-5 htz. As the geophone detects vibration it provides a signal to the electronics that amplify and document it in some form. There are many uses for this device. It's primary function would be to place it in an area where people have reported hearing footsteps and monitor the area with video surveillance. Now you can "see" footsteps rather than just report a personal experience. All matter constantly vibrates and is expressed as a frequency (i.e.- htz) which translates into sound. Although the human ear cannot hear frequencies in the lower spectrum, the geophone can. The sensitivity can be adjusted based upon your preference or need – passive or ultra sensitive. They are not new to the world but they are new in paranormal research.
Another use would be to ask a spirit to touch somewhere in the area of the device or on the geophone itself. You may have seen a video or had a personal experience of communicating with an intelligent spirit by asking 'yes' or 'no' questions and receiving a response on a K2 meter. When this occurs, the spirit activates the K2 lights by manipulating the magnetic fields, however, some people believe very few spirits are capable of manipulating EMF. Touch communication is simply another tool we can use to investigate and further paranormal research.
I have just completed my first geophone build. A company offered kits to build these but, after speaking with them, they will no longer available due to availability of parts. To my knowledge these are not sold at any online paranormal stores. If you are interested in obtaining one of these, click here. If you have any questions, feel free to PM me.

OfflineI too have one of these, and they can be a valuable addition to the 'ol toolchest. I had to build mine into a metal case to get a little more sensitivity out of concrete surfaces. Here is the one I built:
The metal case makes a huge difference with the attenuated signals on concrete or non-padded carpeted concrete.
just curious, what sensor are you using for your geophone? SM-7m? Can you point me to a reliable source for these? US distributors of SENSOR inc's products won't even return an email or answer the phone, so I am currently trying to source just the sensors.
-A.
EDIT: I just read where you said the supplier is discontinuing selling the kits, and that explains a lot. This circuit is obscenely simple to build, all I need is the geophone sensor itself. If anyone can find a source for these, I would appreciate a nudge. As said above, only stateside distributor for the sensor modules are either unable or unwilling to respond to my pricing queries.
OfflineYes, the metal case certainly helps. I thought about this when I built mine in a plastic case. I modified it by cutting the metal mount that came with the case and inserted it for a sturdy bottom. As you said, this is a great piece to add to your tool chest. I was able to obtain a few more sensors which as allowed me adjust things quite a bit. I posted a video demo of it in action at – http://www.mychael.me/geophone.html

OfflineFor anyone who is interested, I have a few more geophones available at GhostWidgets.com.
These are strictly built to order. Supply for this device is EXTREMELY limited. Demand is high but very few people are able to locate these ANYWHERE on the internet. To my knowledge I am the only one offering these to the public. The cost to make them has gone up significantly which has caused me to raise my price. But, I will continue to offer these as long as it remains practical and possible to do so.
OfflineWish I could find a reliable source for the geophone sensor itself. I could build these all day long if I had that sensor. Accelerometers do not do as well, just look at comparisons with the Mel Vibe meter. Oh well, it was cool while it lasted, and glad I got one. If anyone is thinking about getting one, I would do it before the supply line completely dries up. It is a certainty.

I still have a supply available if anyone is interested. I'm not sure when my supply will dry up but I will continue to offer them as long as possible. Visit http://www.GhostWidgets.com.

Guys, if you want a geophone, jump on this. The kits are all gone, and the sensor used in the kits are 110.00 to replace, so it isn't as if you are going to find one cheaper somewhere else. These would be the last of the last. Just sayin'…

OfflineI have geophones available now for $80 – Free Shipping. Visit: http://www.GhostWidgets.com
OfflineFor more Geophones, visit http://www.paranormalstuffonline.com- Our team makes them a little neater than most, and we have an external adjustment potentiometer and an external battery holder (try taking four screws out in the dark and you will know why)- these are extremely sensitive in the plastic enclosures- and come in different colors-
here is a quick demonstration of a sewing needle being dropped at 6 inches-
Thanks,
OfflineI'm a tad late to the thread. Is anyone still selling these?
Yes- http://www.paranormalstuffonline.com- demand is still high, each one is custom built- lead time is roughly 5-7 business days
Thanks,
Jeff
