piece ideas throughout. the pieces should be
considered micro-pieces to be developed between two classes and
presented at the second. a primary piece is to use the images
herein scanned as inspiration for a video piece, sound piece, or
writing. another primary piece is depth-researching any of the
particular materials discussed and presenting it.
the source text was intended for Naval Engineers entering private
enginering fields in communications.
Ah, good old post war america, where supper for everyone
came from our power supply, our damnation. Wind energy as
comfortingly old-world. Our internet in the center.
Peteroleum ever-present cf. "There Will be Blood"
There was blood, in the world, quite recently. A radio
operator may survive because he doesn't have to fight, although he is
still out in the open.
He aches for his buddies,
many who perished.
but now the war is over and he can try to forget
with his hobby and his profession: tubes
you see the technology used to detect the enemy in the warr is now
used for the dovely purpose of receiving programming and playing
tubes were stumbed upon by Monsieur Edison, when he was
tinkering with his light bulbs.
he forsook them, though, for he was in search of lighting
and left them for Fleming, 21 years later, to develop.
Fleming noticed that current only flowed in one direction,
so many shapes and sizes
came about to modulate this flow
the concept is: when heated, the cathode emits electrons
into the physical space within the tube, to be modulated by the various
grids and plates within. you see, the electrons are almost like a
material squeezed within the tube.
i'm thinking of an analogy for this, yes, i think it's sports
sports analogy of physicality: bals
the water analogy of the flow in tubes
top is changing voltage at plate
bottom is modulating the grid
tubes require a high voltage power supply, called "B+", which
requires several mined materials in large quantities.
coil- copper on iron
transformer- copper on paper tube
vacuum tube- glass, wire, ceramic, etc.
any of which could contain PCBs, although it is unlikely,
for PCB oils were used in large transformers,
plenty of which were required by tube power hog circuits,
with many incompatibilities, and much lugging of gear!
The language of electronics bridges to the language of past
sciences. Rectification was initially a very important process in
Alchemy, a process of "Amplifying Gold", with spiritual metaphors.
let us look more at this "amplification"
remember, war technology is the basis of tubesz
it still drives innovations in microwave, ultrasound, tactical
Ronald Reagan, model of physical power,
and his media communications amplification
his charisma and his electricity
an impulse to vote for president
you see amplification is important in communication
here is presented "An History of Communcations"
you will notice that no battery or power is needed for the crystal
converts radio energy directly into (quiet) audio
some of the most "new" ideas are actually very old,
such as low power design
this circuit is all about "tuned"
the coil is one part of a resonance
and the capacitor is the other
the crystal is the magic of rectification
utilizing this tuning resonant tuning technique
and harnessing power of tubes to amplify
design challenges and demons:
hot tubes is a considerable frustration for the anxious inventor
although noise may be beneficial, and of fidelity
cf Aaron Dilloway, "BOGGS"
fundamentally, a radio device will have an oscillator in it, which
classically has been a "pure sinusoid". there are also resonances
in radio circuitry, which are like oscillators, but they are "damped"
so they decay. A transmitter is purely an oscillator, but a
reciever has a combination of reference oscillator and resonances to
"pick up" the transmissions.
In fact, recievers are transmitters, they have their own oscillator
which transmits forth from the device. CF. Quantum Physics-
uncertainty resolution principle- an observer cannot help but affect
a strong arm and a strong hammer
FM was not invented by YAMAHA, but by The Police. In fact the
police have some very baroque types of Frequency Modulation based on
complicated cypher-modulation/skip-band. Martin Howse
the gimmick was originally intended to mean:
"a legitimite way to boost high frequencies,
involving a conjured use of a piece of wire"
farm to penis plane model of communication- rural cycles are an
obviously there are many male military phantasies of delivering
"bangs" straight to the right spot, with this invisible magic, radio.
in fact there are a whole host of military technologies,
to seek the enemy
but in microwave frequencies there is another dragon,
a noticeable change in the physicality of electrons
Actually no PCBs, instead using good old wood fiber, a close
chemical cousin. the use of "ether" is another old world clue.
the thesis here is that, when you look at how they are made and what is
contained in tubes, you can perceive a derivation is historically
derived from the alchemist cf. Hennig Brand discovering phosphorus from
his own urine.
The following are "piece ideas"
intentionally blanked, you can fill in the score
here's a piece idea: a three part sound piece, or
alternatively, a montage composed of three objets-sonores:
loud feedback/noise based on the idea of 3, whether it be
triads, triodes or the trident.
grungy, distorted "SCORE" based on tetrachords, ends
up confusing the listener.
easy listening music suggesting pentagon, pentagram, and pentachords
note: these are Ancient Greek words. "ode" in
tetrode, and pentode indicates "a path", although the word also means
"a recitation of lyric poetry set to music of the kithara". It is
also homonym with "a tusk" in Ancient Greek. A
little bird on my shoulder told me that the tighter tetrachords of the Ancient
System are the spiciest. Model them with
computer music apps.
This one is about video. Against a backdrop of interferance
patterns, a ship on the sea is projecting light. An oscilloscope
projects resonances onto phosphorus, in a vacuum. Adults assemble
around a "set" to watch an entertainer.
you may notice that in the URL of this page, it
"tubesz". That is to differentiate it as "glass vacuum tubes"
apart from another type often used in the conservatory: "horns"
