the boxPoem was completed as a mid-term project
for a phyiscal computing class at ITP.
depending on which way the box is tilted as you hold it in your hand,
a different verse of a poem is heard through small speakers embedded inside
the object. below is an excerpt from the journal i kept during the course,
describing the design process in detail.
foundation
this
midterm project is a modification of an idea i had at the beginning
of the semester. i wanted to explore ways in which poetry can be
rendered as a physical object. experimentation with visual poetry
is centuries old, of particular interest to me is Hrabanus Marus'
De
adoratione crucis ab opifice, i am fascinated by the author's
use of a two-dimensional matrix to structure his thoughts. the twentieth
century was bursting with a vibrant array of concrete poets investigating
the image/text dialogue. poetry in three dimensions, however, still
seems to be an area in need of good preliminary investigations.
i suppose i shouldn't be shocked, after all our grammar is quite
linear and two-dimensional. yet humans have an amazing capacity
to move through space, to localize sounds in their environment -
why not bring this ability into our understanding of words? can
space be semantically meaningful?

object
i
decided to fuse a physical object and a poem. using several voice
record/playback devices and a tilt switch, i made an object that
would play a different verse of my poem depending on how it was
held.
though
i originally wanted to use a ball (actually, a set of at least three
balls), the design troubles were legion. for instance, how would
i insert my circuitry into a ball? if i surgically cut into a rubber
ball, taping my wires and speakers to the sides, would i be able
to close up the incision? what an incredible pain it would be to
change a battery, it would have to be a limited-time-only project.
boo. let's say i found a hard plastic ball, that came apart in the
middle, like an Easter egg. easy access to batteries, nice firm
surface that wouldn't harm my speakers when rolled about. how would
i balance the weight of the circuitry within the ball? a ball that
only rolls to one side does not fit my cognitive schema of a ball.
nope, a lopsided ball just couldn't cut it. i decided upon a cube
for the housing of my circuit poem. a perfect, simple, right-angled
box. |
you have no idea how difficult it is to find a cube. rectangluar
boxes in all colors, materials, and religions are available for
your convenience - but the humble square box, open at one end, is
not readily available. nevertheless i insisted on a cube, so a cube
it must be. wandering around craft and art supply stores proved
futile. nothing like the good ol' 99 cent store, where i finally
chanced upon my grail. true, it was painted with some sort of desperately
trying to be whimsical Halloween ghoul, but that could be remedied.
painting the box would also give me the opportunity to enrich the
object with my own style, rather than settling on factory plexiglass
yellow #5.

circuitry
this
project used the following items:
- one
tilt switch
- three
20-second voice record/playback chips (available at Radio
Shack)
- three
9 V batteries
- housing
for the mess of circuitry
- wires,
solder, electrical tape
the
first problem to solve was determining how to replace the "play"
button of the voice chip with a switch. when the "play"
button is depressed, a small metal disc inside the button momentarily
closes a circuit, and the sound is heard. flipping the circuit board
over, i traced the two interlocking current paths undernearth the
button - one side went to the battery connection's ground, the other
to a resistor.
|
|
i stripped away the black plastic sheath of the ground wire and soldered
a new wire in that place, which would eventually be connected to one
side of my switch. in the picture above, this is the blue wire leading
away from the area labeled "ground".
|
since there was not enough exposed wire from R3 on the back of the
circuit board, i flipped it over and soldered a new wire to R3 from
the front. had to be really careful not to melt the circuit board
or drip solder in an inappropriate place - these are cheap little
suckers!
|
|
after each of the three circuit boards were prepared, i soldered my
six wires to a tilt switch. the process was straightforward, but required
a certain amount of patience and precision. now i just had to place
the medusa-circuitry into some nice housing.

a ssessment
though
the project is relatively simple from a techincal standpoint, i
believe the conceptual basis is rich. the most difficult part was
certainly crafting the poem - i'm the type that can agonize over
a single word. i accomplished what i set out to do, yet several
improvement could be made:
- the
speaker quality is less than desirable- yet a bigger, better,
heavier speaker would mean a bigger cube, and i like the fact
that the poem is handheld.
- to
keep cost down, i had to go with the hardware provided by the
Radio Shack voice record/playback module. the best solution probably
would have been to use one quality speaker, and an integrated
chip that would allow random access to pre-recorded sound bytes.
in the interest of time and my technical ability, i had decided
on the ready-made chip.
- i
could do some research into the design and material of housing
that would serve not only as a container but as a resonant chamber.
though perhaps the cube is too small, and no significant difference
would be detected in the sound quality.
- the
unit is not exactly child-proof. if you were to throw this thing
down the stairs (even gently) its guts would spill out. it is
now 23:56 and i have no idea how to attach the top of the box
securely. nailing it would seem useless - how would i change the
batteries? i stuffed pieces of blue foam (gotta match the exterior)
into much of the interior to cushion rough handling, but who knows
what havoc the fickle fingers of eager users may wreak.
