Nick Sears: Presenting the Orb

Prevodilac: Mile Živković Lektor: Ivana Korom

In 1962, Buckminster Fuller

Godine 1962, Bakminster Fuler

presented the particularly audacious proposal for the Geoscope.

predstavio je naročito odvažan predlog Geoskopa.

It was a 200-foot diameter geodesic sphere

To je bila geodetska sfera prečnika 60 metara

to be suspended over the East River in New York City, in full view of the United Nations.

koja bi visila nad rekom Ist u Njujorku, ispred Ujedinjenih nacija.

It was a big idea, for sure, and it was one that he felt could truly inform

To je svakako bila velika ideja, i mislio je da bi ona mogla da informiše

and deeply affect the decision making of this body

i duboko utiče na odluke ovog tela

through animations of global data, trends

kroz animacije globalnih podataka, trendova,

and other information regarding the globe, on this sphere.

i drugih informacija koje se tiču zemlje, sve na ovoj sferi.

And today, 45 years later,

Danas, 45 godina kasnije,

we clearly have no less need for this kind of clarity and perspective,

postoji jednaka potreba za ovakvom jasnoćom i perspektivom,

but what we do have is improved technology.

ali imamo poboljšanu tehnologiju.

Today we don't need one million light bulbs to create a spherical display.

Danas nam nije potrebno milion sijalica da napravimo sferični displej.

We can use LEDs.

Možemo koristiti LED sijalice.

LEDs are smaller, they're cheaper, they're longer lasting, they're more efficient.

LED sijalice su manje, jeftinije, duže traju i efikasnije su.

Most importantly for this, they're faster.

Najbitnije za nas je to što su brže.

And this speed, combined with today's high-performance micro-controllers,

Ova brzina, u kombinaciji sa današnjim mikrokontrolerima visokih performansi,

allows us to actually simulate, in this piece,

dozvoljava nam da na ovom delu simuliramo

over 17,000 LEDs -- using just 64.

preko 17 000 LED sijalica, koristeći samo 64.

And the way this happens is through the phenomenon of persistence of vision.

Ovo se dešava kroz pojavu koja se naziva istrajnost vida.

But as this ring rotates at about 1,700 rpm -- that's 28 times per second.

Ovaj krug okreće se na oko 1700 obrtaja - to je 28 puta u sekundi.

The equator's speed is actually about 60 miles per hour.

Brzina ekvatora je zapravo oko 100 kilometara na sat.

There are four on-board micro-controllers

Na uređaju postoje 4 mikrokontrolera

that, each time this ring rotates

koji, svaki put kada se ovaj prsten okrene,

it, as it passes the rear of the display,

kada on prođe zadnji deo displeja,

it picks up a position signal.

dobija signal o poziciji.

And from that, the on-board micro-controllers

Mikrokontroleri na uređaju

can extrapolate the position of the ring at all points around the revolution

mogu da izvuku položaj prstena u svim tačkama u toku okretanja

and display arbitrary bitmap images and animations.

i da pokažu arbitrarne slike i animacije.

But this is really just the beginning.

Ali ovo je samo početak.

In addition to higher resolution versions of this display,

Pored verzija ovog displeja sa većom rezolucijom,

my father and I are working on a new patent-pending design

moj otac i ja radimo na novom dizajnu za koji sledi patent

for a fully volumetric display using the same phenomenon.

sa potpuno volumetrijskim displejom koji koristi istu ovu pojavu.

It achieves this by rotating LEDs about two axes.

Ovo se postiže tako što se LED sijalice okreću oko dve ose.

So as you can see here, this is a, eleven-inch diameter circuit board.

Kao što možete ovde videti, ovo je strujno kolo prečnika 27cm.

These blocks represent LEDs.

Ovi blokovi predstavljaju LED sijalice.

And so you could see that as this disc rotates about this axis,

Možete videti da se ovaj disk okreće oko ove ose,

it will create a disc of light that we can control.

stvoriće disk svetlosti koji možemo da kontrolišemo.

That's nothing new: that's a propeller clock;

To nije ništa novo - to je "propeler" sat,

that's the rims that you can buy for your car.

to su felne koje možete kupiti za svoj automobil.

But what is new is that, when we rotate this disc about this axis,

Ali novo je to da kada ovaj disk obrnemo oko ove ose,

this disc of light actually becomes a sphere of light.

disk svetlosti zapravo postaje sfera svetlosti.

And so we can control that with micro-controllers

I to možemo kontrolisati uz pomoć mikrokontrolera i stvoriti

and create a fully volumetric, three-dimensional display with just 256 LEDs.

potpuno volumetrijski, 3D displej uz samo 256 LED sijalica.

Now this piece is currently in process --

Na ovome trenutno još radimo -

due out in May -- but what we've done is we've put together a small demo,

treba da izađe u maju, ali napravili smo malu demonstraciju,

just to show the geometric translation of points into a sphere.

kako bi pokazali geometrijski prelaz tačaka u sferu.

I've got a little video to show you,

Imam video za vas,

but keep in mind that this is with no electronic control,

ali imajte na umu da je ovo bez elektronske kontrole,

and this is also with only four LEDs.

i koristeći samo 4 LED sijalice.

This is actually only about 1.5 percent of what the final display will be in May.

Ovo je zapravo samo 1,5% onoga kako će izgledati konačni displej u maju.

So, take a look.

Pogledajte.

And here you can see it's rotating about the vertical axis only, creating circles.

Ovde vidite da se okreće samo oko svoje vertikalne ose, praveći krugove.

And then, as the other axis kicks in,

Onda nastupa druga osa

those actually blur into a volume.

i njih dve se stapaju u volumen.

And the shutter speed of the camera

Brzina zatvarača na kameri

actually makes it slightly less effective in this case.

u ovom slučaju to zapravo čini nešto manje efektivnim.

But this piece is due out in May.

Ali ovo treba da izađe u maju.

It'll be on display at the Interactive Telecommunications Spring Show

Biće postavljeno na Prolećnoj izložbi interaktivnih telekomunikacija

in Greenwich Village in New York City -- that's open to the public,

u Grinič Vilidžu u Njujorku, biće otvoreno za javnost,

definitely invite you all to come and attend -- it's a fantastic show.

pozivam vas sve da dođete i posetite je, to je fantastična izložba.

There are hundreds of student innovators with fantastic projects.

Tu je stotine studenata inovatora sa fantastičnim projektima.

This piece, actually, will be on display

Ovo delo će zapravo biti postavljeno

down in the Sierra Simulcast Lounge

u sali Sijera simulkast

in the breaks between now and the end of the show.

u pauzama između početka i kraja izložbe.

So I'd love to talk to you all, and invite you

Voleo bih da popričam sa svima vama i da vas pozovem

to come down and take a closer look.

da dođete i pogledate za sebe.

It's an honor to be here. Thanks very much.

Čast je biti ovde. Mnogo vam hvala.
