</tt>#5 | GHOST DETECTOR<br>
-------------------<br>
<br>
<span class="">For the ghost detector, a coil (like the antenna of
a radio but with no tuning magnet) is constructed using fine
copper wire around a cylindrical object of the users choice:
preferably cylindrical in shape, and preferably a "charged"
object (one with personal meaning or of natural origin. Examples
include an animal bone, a sex toy, a sacrificial knife, but
really any cylindrical object will produce results). The coil
diameter and number of windings is variable and experimental and
will produce different results / capture different parts of the
radio and electromagnetic spectrum. Also using the inverting or
non-inverting inputs of the 386 will produce different results.<br>
<br>
In place of the coil it is also possibl<span class="">e to add a
choke and diode (thus the circuit becomes an amplified version
of the Raudive diode), or the play or record head from an old
tape recorder. The results will vary according to the head
used, for example bigger heads out of reel to reel machines
will be more sensitive.<br>
A volume control may be added using a potentiometer either at
the input (coil end) or output of the circuit.<br>
The circuit may be constructed by soldering the components
directly to the LM386, or veroboard may be used.<br>
Once the circuit is constructed (should take maximum 2 hours)
you can go on a ghost walk with your device and headphones (or
a recording device if you have one) to listen to hidden spooky
sounds.<br>
<br>
The static charge detector takes advantage of the fact that
CMOS chips are static sensitive to cause a flip-flop to switch
according to the positive or negative ions around the antenna,
lighting one of the LEDs. This can be constructed 'dead bug'
style. The 3M resistor before the antenna protects the chip
against large static spikes. See schematic / photo for
construction details.<br>
<br>
PARTS (Ghost Detector):<br>
LM386<br>
10 uf and 220 uf capacitors<br>
Veroboard (optional)<br>
Fine copper wire to make the antenna coils<br>
9v BATTERY CONNECTORS<br>
9v battery<br>
3.5mm headphone socket<br>
- An object to wrap your coil around to make the ghost
detector antenna. The small circuit and battery will also be
attached to this antenna.<br>
Headphones<br>
<br>
PARTS (Static Detector)<br>
CD4011<br>
resistors 270ohm and 3Mohm<br>
Capacitors 33pf<br>
Diodes 1N4148<br>
9v battery connector<br>
<br>
OTHER STUFF:<br>
- SOLDERING IRONS (one per person is ideal but can be shared
if less)<br>
- SOLDER (flux core, as thin as possible)<br>
- Electrical tape (insulation tape) or gaffer tape<br>
- glue gun<br>
- Wire to recycle (for example old computer cables / Ethernet
cable / telephone cable)<br>
- Cables 3'5mm mono to 1/4" jack if people want to plug their
machines into a mixer or amp and record.<br>
- Mixer and amp<br>
<br>
WHAT PARTICIPANTS SHOULD BRING:<br>
a cylindrical; non-conductive object to wrap wire around to
make an antenna,<br>
preferably something personal and/or from a dead
animal/person/plant.<br>
Also headphones, and a 9v battery</span></span><br>
