</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>

April 2015, consisting in a public talk and a collective
workshop.</span></div>
<div class="ace-line" id="magicdomid2328"><span class="">Since 2006,
Mal au Pixel festival is looking at connecting technology, urban
electronics and social transformation issues, and to
investigate our contemporary beliefs. The festival brings
