In 1962, Buckminster Fuller
0
1000
2000
1952.godine, Buckminster Fuller
00:21
presented the particularly audacious proposal for the Geoscope.
1
3000
4000
je iznio naročito drzak prijedlog za Geoscope.
00:25
It was a 200-foot diameter geodesic sphere
2
7000
3000
Bila je to dijametrična geodezična sfera od 60ak metara
00:28
to be suspended over the East River in New York City, in full view of the United Nations.
3
10000
5000
koja bi bila obješena preko East Rivera sve u New York City, s potpunim pogledom na Ujedinjene Narode.
00:33
It was a big idea, for sure, and it was one that he felt could truly inform
4
15000
6000
Bila je to velika ideja, zasigurno, i jedna od onih za koju je osjećao da bi uistinu mogla informirati
00:39
and deeply affect the decision making of this body
5
21000
4000
i duboko utjecati na donošenje odluka tog tijela
00:43
through animations of global data, trends
6
25000
4000
kroz animacije globalnih podataka, trendova
00:47
and other information regarding the globe, on this sphere.
7
29000
4000
i drugih informacija koje se tiču kugle, na toj sferi.
00:51
And today, 45 years later,
8
33000
3000
I danas, 45 godina kasnije,
00:54
we clearly have no less need for this kind of clarity and perspective,
9
36000
3000
mi očito nemamo manju potrebu za takvom vrstom jasnoće i perspektive,
00:57
but what we do have is improved technology.
10
39000
3000
ali ono što imamo je poboljšana tehnologija.
01:00
Today we don't need one million light bulbs to create a spherical display.
11
42000
3000
Danas nam nije potrebno milijun žarulja kako bi stvorili sferični zaslon.
01:03
We can use LEDs.
12
45000
2000
Možemo koristiti LED diode.
01:05
LEDs are smaller, they're cheaper, they're longer lasting, they're more efficient.
13
47000
5000
LED-ice su manje, jeftinije su, duže traju, efikasnije su.
01:10
Most importantly for this, they're faster.
14
52000
2000
Ali najvažnije za ovo, one su brže.
01:12
And this speed, combined with today's high-performance micro-controllers,
15
54000
4000
A ta brzina, u kombinaciji s današnjim mikro-kontrolorima visokih performansi
01:16
allows us to actually simulate, in this piece,
16
58000
3000
omogućili su nam da zapravo simuliramo, u ovom dijelu,
01:19
over 17,000 LEDs -- using just 64.
17
61000
4000
preko 17.000 LED-ica -- koristeći samo 64.
01:24
And the way this happens is through the phenomenon of persistence of vision.
18
66000
4000
A način na koji se to događa je putem fenomena dosljednosti prikaza.
01:28
But as this ring rotates at about 1,700 rpm -- that's 28 times per second.
19
70000
4000
Ali kao što taj prsten rotira na oko 1.700 okretaja po minuti -- to je 28 puta u sekundi.
01:33
The equator's speed is actually about 60 miles per hour.
20
75000
3000
Brzina ekvatora je zapravo oko 97 kilometara na sat.
01:36
There are four on-board micro-controllers
21
78000
2000
Na njemu se nalazi četiri mikro-kontrolora
01:38
that, each time this ring rotates
22
80000
3000
koji, svaki put kada ga prsten zarotira,
01:41
it, as it passes the rear of the display,
23
83000
2000
kako prolazi stražnjim dijelom zaslona,
01:43
it picks up a position signal.
24
85000
2000
pokupi pozicijski signal
01:45
And from that, the on-board micro-controllers
25
87000
2000
i iz toga, postojeći mikro-kontrolori
01:47
can extrapolate the position of the ring at all points around the revolution
26
89000
5000
mogu izvršiti ekstrapolaciju pozicije prstena na svim točkama oko revolucije
01:52
and display arbitrary bitmap images and animations.
27
94000
3000
i zaslona proizvoljnih bitmap slika i animacija.
01:55
But this is really just the beginning.
28
97000
3000
Ali to je stvarno samo početak.
01:58
In addition to higher resolution versions of this display,
29
100000
3000
Nastavno na verzije tog zaslona viših rezolucija,
02:01
my father and I are working on a new patent-pending design
30
103000
3000
moj otac i ja radimo na novom dizajnu koji čeka odobravanje patentnog ureda
02:04
for a fully volumetric display using the same phenomenon.
31
106000
3000
za potpun volumetrični zaslon koristeći isti fenomen.
02:07
It achieves this by rotating LEDs about two axes.
32
109000
3000
Postiže to rotirajući LED-ice oko dvije osi.
02:10
So as you can see here, this is a, eleven-inch diameter circuit board.
33
112000
3000
Kao što možete vidjeti ovdje, ovo je matična ploča promjera 28 centimetara.
02:13
These blocks represent LEDs.
34
115000
2000
Ovi blokovi predstavljaju LED-ice.
02:15
And so you could see that as this disc rotates about this axis,
35
117000
4000
I možete vidjeti kako taj disk rotira oko tih osi,
02:19
it will create a disc of light that we can control.
36
121000
3000
on će kreirati disk svjetla koji možemo kontrolirati.
02:22
That's nothing new: that's a propeller clock;
37
124000
2000
To nije ništa novo, to je propelerski sat.
02:24
that's the rims that you can buy for your car.
38
126000
3000
To su naplatci koje možete kupiti za svoj auto.
02:27
But what is new is that, when we rotate this disc about this axis,
39
129000
5000
Ali ono što je novo, je da kada rotiramo disk oko tih osi,
02:32
this disc of light actually becomes a sphere of light.
40
134000
3000
sada disk svjetlo zapravo postaje sfera svjetlo.
02:35
And so we can control that with micro-controllers
41
137000
2000
I tako mi to možemo kontrolirati s mikro-kontrolorima
02:37
and create a fully volumetric, three-dimensional display with just 256 LEDs.
42
139000
6000
i stvoriti potpun volumetričan, trodimenzionalan zaslon sa samo 256 LED-ica.
02:43
Now this piece is currently in process --
43
145000
2000
Sada, taj dio je trenutno u procesu --
02:45
due out in May -- but what we've done is we've put together a small demo,
44
147000
5000
trebao bi izaći u svibnju, ali ono što smo napravili jest da smo sastavili zajedno mali demo,
02:50
just to show the geometric translation of points into a sphere.
45
152000
4000
samo kako bi vam prikazali geometrijski prijelaz točaka u sferu.
02:54
I've got a little video to show you,
46
156000
2000
Imam kratak video koji vam želim pokazati,
02:56
but keep in mind that this is with no electronic control,
47
158000
4000
ali imajte na umu kako je ovo bez elektroničke kontrole,
03:00
and this is also with only four LEDs.
48
162000
2000
i to je ujedno samo s četiri LED-ice.
03:02
This is actually only about 1.5 percent of what the final display will be in May.
49
164000
3000
To je zapravo samo oko 1,5 posto onoga kakav će završni zaslon biti u svibnju.
03:05
So, take a look.
50
167000
2000
Dakle, pogledajte.
03:09
And here you can see it's rotating about the vertical axis only, creating circles.
51
171000
4000
I ovdje možete vidjeti kako rotira samo oko vertikalne osi, stvarajući krugove.
03:17
And then, as the other axis kicks in,
52
179000
2000
A zatim, kako se druga os priključuje,
03:19
those actually blur into a volume.
53
181000
2000
one se zapravo stope u jednu.
03:21
And the shutter speed of the camera
54
183000
2000
A brzina zatvarača na fotoaparatu
03:23
actually makes it slightly less effective in this case.
55
185000
3000
je čini zapravo malo manje efikasnijom u ovom slučaju.
03:26
But this piece is due out in May.
56
188000
2000
Ali ovaj dio treba izaći u svibnju.
03:28
It'll be on display at the Interactive Telecommunications Spring Show
57
190000
3000
Bit će prikazivan na Proljetnom sajmu interaktivnih telekomunikacija
03:31
in Greenwich Village in New York City -- that's open to the public,
58
193000
2000
u Greenwich Village-u u New York City-u -- otvoreno je za javnost,
03:33
definitely invite you all to come and attend -- it's a fantastic show.
59
195000
4000
definitivno pozivam sve vas da dođete -- to je fantastičan sajam.
03:37
There are hundreds of student innovators with fantastic projects.
60
199000
4000
Tamo dolaze stotine studenata inovatora s fantastičnim projektima.
03:41
This piece, actually, will be on display
61
203000
2000
Ovaj komad, zapravo, će biti prikazivan
03:43
down in the Sierra Simulcast Lounge
62
205000
2000
dolje u Sierra Simulcast Lounge-u
03:45
in the breaks between now and the end of the show.
63
207000
2000
u periodima između sada i kraja sajma.
03:47
So I'd love to talk to you all, and invite you
64
209000
2000
Stoga bih volio popričati sa svima vama, i pozvati vas
03:49
to come down and take a closer look.
65
211000
2000
da dođete dolje i pobliže to pogledate.
03:51
It's an honor to be here. Thanks very much.
66
213000
2000
Čast je biti ovdje, puno hvala.
03:53

ABOUT THE SPEAKER
Nick Sears - InventorWorking with his father, Ron Sears, Nick Sears is designing and building the Orb, a rotating LED display that uses persistence of vision to produce moving images in 3D space.
Why you should listen
Nick Sears is a classic tinkerer -- his resume lists jobs that run the gamut from writing a mobile messaging framework to building a DC-DC switching voltage regulator. Along with his dad, Ron Sears, he's got a pretty neat father-son project going on: the Orb.
It's inspired by Buckminster Fuller's 1962 proposal for the Geoscope, which called for "a 200-foot-diameter sphere covered with 10 million computer-controlled light sources to be suspended over the East River in full view of the United Nations." But by making the sphere spin, the Sears realized, they could use persistence of vision and LEDs to create a bright display with a three-dimensional effect using far fewer light sources.
Sears is now a student in the Interactive Telecommunications Program at NYU. He and his father presented the Orb version 2 at Coachella in 2008 and continue to tinker with it.
