Early last decade there an idea was pursued about how the
American-English alphabet had a common structure. It is not
known exactly how this idea arose, only that it related directly
to works of art that explored similar ideas (Jasper John's super-
imposing of numbers atop one another and alphabets; Jenny
Holzer's scrolling LED displays with multiple languages). This
common structure in language was related to ideas of structure
in buildings which was a focus. In an attempt to explore this idea,
the alphabet was graphically diagrammed as a 4 dimensional
object in 3D space with temporal change, in that the alphabet
would be flipped and twisted on a set of axes, in search of...
Sure enough, weird stuff was realized such that Plato wrote about
this idea of reflecting letters and numbers, their materiality. And so
too, the alphabet had a few major surprises, taken out of its major
context of linguistic definition- a common symbol was found that is
a more square version of that which is in the Union Jack of the UK,
otherwise known (online) as HIOX as these four letters are able to
exist almost the same in 4D space-time. Oddly, the symbol was to
be realized when searching for the common structure, it was not a
predetermined or even known symbol, it was just a hypothesis that
there may be a structure. John's work asked the question, Holzer's
work demonstrated that in technology this must have been dealt
with (for use in electronic signage) and thus, looking for patterns
in digital/light-displays on elevators and in LCDs was part of the
search for patterns. Yet it was always conceived that it only was
to exist in a dot-matrix existence, of separate bulbs of information
presented as a symbol. While a more richly symbolic HIOX existed
as a geometry in early Western classical architecture and present-
day (.US) federal architecture, amongst other places.

[*I never saw this piece, only a painting of this same idea, which has
been logically concluded in the 7 segment light emitting diode display.
It is unfortunate all of these alphabetic works are not available
online.
Also, Jenny Holzer's electronic work is not available via imagery now.]
This idea was only barely investigated as it was so abstract and
of no utility other than logic and generative patterning, aesthetics,
and a thesis about language and mathematics that it was mainly
ignored because it was too weird to talk about. If life was different
there would have been Schroedinger's Cat logical models using
this HIOX model to demonstrate 'paradoxical logic' beyond in the
everyday experience, by having these rotating alphabets running
in 4D via electric motors, so one would question if it was a 3 or E
that presented itself, an M or W, a Z or S or N. It seems very sad
to write about what-if's, what might have happened, yet underneath
the effort to learn basic electronics was to create a manual model
of the HIOX in LEDs, and then to manually use switches and a lot
of arcane amounts of wires and power to make this array of lights
create this dot-matrix-like symbol, which would then be a way to
begin discussing this idea, as one of the 40+ switches could show
that the alphabet and numbers all exist in one common symbol,
in a caveman-meets-electronics aesthetic. (In these examples it
is jewelry, but it could be cryptographic I have always imagined).

So, working on this idea, not overtly or even consciously, though
in relation it is something which caused interest in this direction
of skill building. So it was to my great surprise when sometime
last week after having gone electronics-surplussing that all the
LEDs and strange 5 position giant switches and diodes and the
resisters that were gathered for this sketch of an idea become
instantly irrelevant when the actual HIOX symbol was found to
be already in existence, yet not easily available, it was located
online, and local shops do not carry this alphanumeric display.
The first time I saw this HIOX shape in a manufactured one-piece
LED alphanumeric display was, at first, completely beyond belief.
And then, I realized it was a lack of information about electronics,
and having seen enough to realize that there is a genealogy to
the development of technologies, and if there is a 7-segment
display for generating the numbers 0-9 using 7 segments of
Light Emitting Diodes, then how would they do the alphabet?
It is referred to as a 16 segment display, in some instances.

( click 'larger display' to see the HIOX pattern. there is also a single
version but the symbol is less visible. for a lot more types of these
alphanumeric LED (and LCD) displays at http://www.digikey.com/ )
In any case, as soon as I found out about this, it was realized it was
not one of a kind technology but has been around (and likely will
someday be replaced by LCDs and eventually OLEDs as a display
technique, etc.), as they are seemingly rare for local electronics
gear.
I asked someone, actually two people, about this technology and they
told me to get the specs (which I found at digikey for many other
displays)
and it seemed to be 'do-able' in the sense that I would not have to
create
the HIOX icon myself, as it is already in existence, and then the idea
could move on to making the letters and numbers in this common symbol.
First chance, calls were made locally to find out that the main places
for
surplus and electronics carried only the seven segment numerical LED
displays, and not the alphanumeric ones, as they were said to be rare,
or at least not in demand. After going on a journey the seven segment
display was obtained for an experiment, to learn how such displays
work.
And there was another surprise. Having worked on learning basics of
electronics, a pre-assemblage kit with workbook and solderless bread-
board was worked with, to demonstrate fundamentals. A more intense
digital kit awaits investigation as there is something about circuits
and
mathematics that makes it hard to just plug wires into circuit diagrams
that are built on these boards, which may or may not work, and have
no one to ask questions to that are not explained or in the book or
even
part of the approach, so trial and error and limited self-exploration
were
both the process and limitation, which was where things were at until
trying to go beyond this with building something customized and then
learning from it. All this to say that having earlier worked with one
IC
(integrated circuit) in the kit, and seeing how it was a mystery device
whose operations and abilities were undocumented and unknown- it
just did what it did and 'worked' - it was in futzing with the
7-segment
LED that much more became clear.
If one places limited voltage on one of the legs that extend from the
LED display, one section of the seven segments will light up, and
these are mapped from their electrical connectors/contacts, to the
LED segments which light up. So, this would be the same with the
more complex HIOX/alphanumeric display, it is assumed. Yet, with
great interest some testing of the numerical display indicated it was
possible to 'drive' the display which was shown in an old handbook
from years ago at a Radio Shack in California, which showed such
a circuit which I am now trying to build with different parts that are
available (some are not, thus experimenting continues). In any case,
the important discovery was that the numbers 0-9 could be animated
by a 'clock' that is run by sending electrical current through a
circuit,
with an integrated circuit doing the counting and cycling of the
display
through all the numbers. This means that it may be possible there is
another one of these ICs for driving the alphanumeric display through
all the letters and numbers of the alphabet (upper and lowercase even)
in one symbol, and doing this automatically without having to use all
of the manual switches, potentially, should these chips exist and if
they can be figured out (with help from others) in some basic way.
An integrated circuit is like a small rectangular slab of dark ceramic
or some material with metal legs that make it look to be an insect of
sorts, which has transistors and diodes and logic gates built into it.
Up until this point I was thinking that to drive the HIOX display would
then require a custom programmed chipset, which it still may, and
which would be out of the realm of the possible for the time being,
yet eventually possible given infinite time and extremely better luck.
And using a Mac OS X computer, the technology used by educators
to teach this technology (Basic STAMP and Board of Education, URL:
http://www.parallax.com/detail.asp?product_id=28102 and also
http://www.parallax.com/html_pages/edu/index.asp ) was at first not
possible (serial port communications to program a microcontroller
chip) yet someone wrote code to make it work, thus it is not off-the-
table for people with non-PC hardware and software to approach.
To sum up the saga thus far, all the parts to make the HIOX display
manually were found to be irrelevant as the industry needed such
a display and manufactured it, and it has evolved beyond this yet it
is critical proof that there is a common structure in the alphanumeric
display of the American English alphabet and 0-9 number system.
The approach to do this with a series of rather large slide switches
has instead potentially been made irrelevant by the use of either
integrated circuits to drive displays and-or microcontrollers (for the
industry) and yet this may or may not be within the domain of the
novice, to explore and have some success amongst likely failures.
It is very exciting as it is to learn about technologies and ways of
doing things that are hard to consider if they're invisible or not
known about or never experienced. So in a sense, in approaching
electronics one goal was to try to gain a materialistic understanding
of how computer programming logic works on the (circuit) board,
with transistors, but also to hopefully help in integrating hardware
and software, and online and offline events. For instance, with a
little knowledge in electronics, a crude prototype may be made
which could demonstrate an idea for, say, an architectural device
which would communicate as an infrastructure in an environment,
or may create a type of space or experience using microphones
and video and lasers and sensors to activate space, as has been
done by installation artists before, but for other purposes/designs.
It is this loop between the art and the science and technology that
became more and more apparent, not the academic or ideological
connect the dots which always seems to not have the guts of the
subject in its definition, only on its surface theorizing. Yet in the
realm of the hypothesis, when ideas may not work, where what is
undiscovered or unknown or guessed, or simply questioned and
for generations and in a way it is known but investigated and then
known more or in different or more specific ways, it is this type of
investigation and interrogating of electromagnetism that is in some
way in relation to what is experienced in the development of today.
That is, people are parsing data, making things, considering, and
some questions remain unanswered and science and technologies
and arts are swirling around these, and none of them capture the
entirety of the moment in its essence, yet there are odd parallels
where a 0-9 painting in the 1960s that is searching for a common
structure in visual language is related to Plato's language calculus
at the same time as being synchronous with the development of
LED displays technologies and computing when the first digital
watches and such technologies were just coming into existence.
This is said not as a glorification of anything specific. Instead it is
about an idea, and a type of archaeology of works that span a lot
of different disciplines. And how interesting it would be if all of the
people today who are so talented in one realm were to learn more
of the other realms, so that the language would be related to the
mathematics involved in making ideas real, where computer art
is not separated from understanding of the hardware dimensions,
but further, the electronics, and how internet artworks may relate
by sheer structural genealogy to installation art and even the art
created for world's fairs by the earliest 'lighting engineers' which
made events and performances predating all current histories
of where and when the modern gained its force, structure, form.
Hopefully some day some of these connections, integrations of
knowledges, and ideas in relation to their tangible and intangible
aspects will be related, recontextualized, requestioned and even
understood in a way unlike anything, yet as a tradition of culture.
In this way, a simple approach and quite isolated struggle to learn
the most basic thing about the most prevalent force in society is,
in itself, informative and inspiring to the degree that meaning is
found in this approach, and others' experiences and works seem
to indicate it is not an isolated adventure, yet everyone is talking
in different ways, with different approaches, and if there was a
commonality, a basis, a shared interest, in learning, maybe it
would be easier to learn about what already exists in other
segments of the wold and society, maybe things could be done
that individuals cannot do alone, and maybe the science can be
informed more by the art, and educationally understood more
creatively through the arts, raising awareness but also giving
meaning to technical exercises so that something like robotics
is about the ideas of robotics, not just making robots, so too the
arts and sciences. And it is believed learning a bit more about
electromagnetism would open up a lot of new possibilities for
both those younger and older, if there was a way to begin to
cross-pollinate the people, ideas, professions, and institutions.
In any case, this is a lot of fun and quite scary to try to figure out
on one's own,, and it is hoped a community will find organization.
