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

To je svakako bila velika ideja,

00:51
And today, 45 years later,
8
33000
3000
Danas, 45 godina kasnije,
00:54
we clearly have no less need for this kind of clarity and perspective,
9
36000
3000
postoji jednaka potreba za ovakvom
jasnoćom i perspektivom,
jasnoćom i perspektivom,
00:57
but what we do have is improved technology.
10
39000
3000
ali imamo poboljšanu tehnologiju.
Danas nam nije potrebno milion sijalica
da napravimo sferični displej.
da napravimo sferični displej.
01:00
Today we don't need one million light bulbs to create a spherical display.
11
42000
3000
01:03
We can use LEDs.
12
45000
2000
Možemo koristiti LED sijalice.
01:05
LEDs are smaller, they're cheaper, they're longer lasting, they're more efficient.
13
47000
5000
LED sijalice su manje, jeftinije,
duže traju i efikasnije su.
duže traju i efikasnije su.
01:10
Most importantly for this, they're faster.
14
52000
2000
Najbitnije za nas je to što su brže.
01:12
And this speed, combined with today's high-performance micro-controllers,
15
54000
4000
Ova brzina, u kombinaciji sa današnjim
mikrokontrolerima visokih performansi,
mikrokontrolerima visokih performansi,
01:16
allows us to actually simulate, in this piece,
16
58000
3000
dozvoljava nam da na ovom delu simuliramo
01:19
over 17,000 LEDs -- using just 64.
17
61000
4000
preko 17 000 LED sijalica,
koristeći samo 64.
koristeći samo 64.
01:24
And the way this happens is through the phenomenon of persistence of vision.
18
66000
4000
Ovo se dešava kroz pojavu koja se naziva
istrajnost vida.
istrajnost vida.
01:28
But as this ring rotates at about 1,700 rpm -- that's 28 times per second.
19
70000
4000
Ovaj krug okreće se na oko 1700 obrtaja -
to je 28 puta u sekundi.
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 100 kilometara na sat.
oko 100 kilometara na sat.
01:36
There are four on-board micro-controllers
21
78000
2000
Na uređaju postoje 4 mikrokontrolera
01:38
that, each time this ring rotates
22
80000
3000
koji, svaki put
kada se ovaj prsten okrene,
kada se ovaj prsten okrene,
01:41
it, as it passes the rear of the display,
23
83000
2000
kada on prođe zadnji deo displeja,
01:43
it picks up a position signal.
24
85000
2000
dobija signal o poziciji.
01:45
And from that, the on-board micro-controllers
25
87000
2000
Mikrokontroleri na uređaju
01:47
can extrapolate the position of the ring at all points around the revolution
26
89000
5000
mogu da izvuku položaj prstena
u svim tačkama u toku okretanja
u svim tačkama u toku okretanja
01:52
and display arbitrary bitmap images and animations.
27
94000
3000
i da pokažu arbitrarne slike i animacije.
01:55
But this is really just the beginning.
28
97000
3000
Ali ovo je samo početak.
01:58
In addition to higher resolution versions of this display,
29
100000
3000
Pored verzija ovog displeja
sa većom rezolucijom,
sa većom rezolucijom,
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
za koji sledi patent
za koji sledi patent
sa potpuno volumetrijskim displejom
koji koristi istu ovu pojavu.
koji koristi istu ovu pojavu.
02:04
for a fully volumetric display using the same phenomenon.
31
106000
3000
02:07
It achieves this by rotating LEDs about two axes.
32
109000
3000
Ovo se postiže tako što se LED sijalice
okreću oko dve ose.
okreću oko dve ose.
02:10
So as you can see here, this is a, eleven-inch diameter circuit board.
33
112000
3000
Kao što možete ovde videti,
ovo je strujno kolo prečnika 27cm.
ovo je strujno kolo prečnika 27cm.
02:13
These blocks represent LEDs.
34
115000
2000
Ovi blokovi predstavljaju LED sijalice.
02:15
And so you could see that as this disc rotates about this axis,
35
117000
4000
Možete videti da se ovaj disk
okreće oko ove ose,
okreće oko ove ose,
02:19
it will create a disc of light that we can control.
36
121000
3000
stvoriće disk svetlosti
koji možemo da kontrolišemo.
koji možemo da kontrolišemo.
02:22
That's nothing new: that's a propeller clock;
37
124000
2000
To nije ništa novo - to je "propeler" sat,
02:24
that's the rims that you can buy for your car.
38
126000
3000
to su felne koje možete
kupiti za svoj automobil.
kupiti za svoj automobil.
02:27
But what is new is that, when we rotate this disc about this axis,
39
129000
5000
Ali novo je to da kada ovaj disk
obrnemo oko ove ose,
obrnemo oko ove ose,
02:32
this disc of light actually becomes a sphere of light.
40
134000
3000
disk svetlosti zapravo postaje
sfera svetlosti.
sfera svetlosti.
02:35
And so we can control that with micro-controllers
41
137000
2000
I to možemo kontrolisati
uz pomoć mikrokontrolera i stvoriti
uz pomoć mikrokontrolera i stvoriti
02:37
and create a fully volumetric, three-dimensional display with just 256 LEDs.
42
139000
6000
potpuno volumetrijski, 3D displej
uz samo 256 LED sijalica.
uz samo 256 LED sijalica.
02:43
Now this piece is currently in process --
43
145000
2000
Na ovome trenutno još radimo -
02:45
due out in May -- but what we've done is we've put together a small demo,
44
147000
5000
treba da izađe u maju, ali napravili smo
malu demonstraciju,
malu demonstraciju,
02:50
just to show the geometric translation of points into a sphere.
45
152000
4000
kako bi pokazali geometrijski prelaz
tačaka u sferu.
tačaka u sferu.
02:54
I've got a little video to show you,
46
156000
2000
Imam video za vas,
02:56
but keep in mind that this is with no electronic control,
47
158000
4000
ali imajte na umu da je ovo
bez elektronske kontrole,
bez elektronske kontrole,
03:00
and this is also with only four LEDs.
48
162000
2000
i koristeći samo 4 LED sijalice.
03:02
This is actually only about 1.5 percent of what the final display will be in May.
49
164000
3000
Ovo je zapravo samo 1,5% onoga
kako će izgledati konačni displej u maju.
kako će izgledati konačni displej u maju.
03:05
So, take a look.
50
167000
2000
Pogledajte.
03:09
And here you can see it's rotating about the vertical axis only, creating circles.
51
171000
4000
Ovde vidite da se okreće samo
oko svoje vertikalne ose, praveći krugove.
oko svoje vertikalne ose, praveći krugove.
03:17
And then, as the other axis kicks in,
52
179000
2000
Onda nastupa druga osa
03:19
those actually blur into a volume.
53
181000
2000
i njih dve se stapaju u volumen.
03:21
And the shutter speed of the camera
54
183000
2000
Brzina zatvarača na kameri
03:23
actually makes it slightly less effective in this case.
55
185000
3000
u ovom slučaju to zapravo čini
nešto manje efektivnim.
nešto manje efektivnim.
03:26
But this piece is due out in May.
56
188000
2000
Ali ovo treba da izađe u maju.

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.
