Detection workshop

We can attempt a rough, non-exhaustive division or classification by way of carrier (excitation), although, at the same time, the choice of carrier usually dictates the subsequent detection technique (the resolving of a signal).

• audible/sound
  

  Excitation by way of wide-band white noise flooding the room (generated electronically and/or through amplification of physical processes such as running water). The magnetic tape or cassette recorder is used as a detector, with recordings played back for subsequent aural analysis (detection). Recordings are also made with no excitation or carrier, and the recorder is also used where any audible detection is implied (with, for example, excitation by way of radio waves, detection by diode). This audible form of detection characterises EVP practice, as opposed to ITC, which embraces all forms of technological trans-communication.

• low frequency electromagnetic phenomena (radio waves)
  

  

  Encompassing excitation by way of radio transmission (the use of a signal generator within Raudive's autotransmission method, the use of high frequency (HF) or HF modulated white noise). Detection is by way of the simple diode detector (a germanium diode attached to the tape recorder), or stock AM radio receiver. Excitation can also be ignored or handed off to other parties (the inter-frequenz method of Raudive tuning between broadcast stations, the various frequencies assigned by different researchers such as Juergenson). Subject to further encodings we could also group here messages received by way of telegraph (in Morse code) and by telephone (Phone Calls From the Dead - 1980 - Rogo and Bayless).

  Radio frequencies for EVP

  Jurgenson frequency range: medium wave (MW) 1480 KHz (1,48 MHz)

  Hans Otto Koenig frequency range: short wave (SW 31 m band 10 MHz and SW 41 m band 7 MHz)

  Marcello Bacci frequency: SW 7 to 9 Megahertz,

  Raymond Cass frequency: 127 MHz (air band frequency).

• (visible) light
  

  

  We can group here the provision of a light carrier (the ultrafon), and the detection by way of photomultiplier tubes, photodiodes and light sensitive materials (photographic film and paper), with the latter detection ushering in the realm of thoughtography (Ted Serios, Tomokichi Fukurai). The work of Klaus Schreiber (Rainer Holbe. Bilder Aus dem Reich der Toten. 1987.) is exemplary in the refining the use of video technology within ITC practice.

  • magnetometer and mirrors
  • own scan lines/webcam software:

  file:/root/collect2010/code\_ref/python/static.py

• ultrasound and infrasound
  

  

  Few experiments are documented, but mention is made of a Mr Stark, experimenting with the modulation of an ultrasonic carrier through arrangements of thin tubing.

(radios, tape recorders, video machines, floppy drives, hard drives, cdrom)

• floppy notes:
  

  Recording (and playback of) looped impulses (only as encoding is MFM. These are generated by an attached 40106 CMOS oscillator) to floppy disk data write.

  Connect pins:

  • 12 (drive select 1) to GND (GND as bottom row of pins)
  • 16 (motor enable 1) to GND
  • 30 (data read) and 32 (select head?) to audio output
  • 22 (data write) to the output of the oscillator (40106 with 1n to GND and finger resistance)
  • also 18 and 20 (stepper) to GND (and 8 (index) to 20) to move head

ranging across radio, ultrasonics, white noise, light and vibration will be constructed alongside

during the following day's excursion [include geophony, amateur geo-forensics and the construction of ad-hoc seismometers, dowsing, excavation, and forensic enquiry]

• notes
  

  how to investigate materials? by subjecting materials to process(es) and observation(s)/(visible, feeling, measuring, hearing, smelling)

  processes such as: hitting, heating, dissolving, electrical, electrochemical, magnetic, chemical, crumbling, wetting, adding to, mixing, scraping

  methodologies: esoteric (EVP,ITC, dowsing), scientific (towards an end eg. farming, analysis and destructuring), aesthetics, forensics (as science also), archaelogical, epistemic- investigation of materials as a revealing, fetishistic

  crypt and cryptography. inscription and digging

  technicals:

  • geophone: on ground and listen to echoes of dropping large object (bucket of…)
  • soil/electrochemical analysis
  • some way of tracing/recording/playing inscriptions (laser as in laser reflective listening - TESTED
  • HD as seismometer (look at lever/pendulum)
  • dowsing rods/ mobile electrometer. changes in potential

  

  • floppy/VHS/CD environmental reading/playback
• geophone examples:
  

  

  • loudspeaker with weight glued to it or suspended from tin/jar-lid
  • HD
  • magnet on rubber band suspended in coil

also will be set up at a new location.

• for light, EM (mini-scry), white noise, magnetic field, wide spectrum, temperature
• also audio (voice activated)

• scaling one data set against another:

  plot "/mnt/monk66" using 3 with lines, "/mnt/monk66" using ($1)/1000 with lines
  

set terminal png size 1024,768
set output "/root/projects/scotland/newcastle/n2/monk01.png"
plot "/root/olderprojects/scotland/newcastle/n2/monk01" index 0 using 0:($1-160) with lines, "/root/olderprojects/scotland/newcastle/n2/monk01" index 0 using 2 with lines

• and how to overlay graphs?

  set multiplot
  set style line 1 linecolor rgb "green"
  plot "whitenoise06022011.log" w lines ls 1
  

for primary inscription and playback of the stone tape.

Other activities will include scrying, geophony, amateur geo-forensics and the construction of ad-hoc seismometers, dowsing, excavation, geomancy (interpretation of thrown earth, cracks, features) and forensic enquiry (see above).

The hard drive is stripped of all main components other than frame and the magnet/coil assembly (the read/write head). A spring or rubber band is attached to the tip of the r/w head and stretched/attached at the other end to the hard drive frame or body (at the top). A weight (a bolt) is hung from the head. A differential op-amp is wired to the coil.

A large coil was also used with a spring-suspended magnet.

The amplifier and filter circuit were based on:
