In 1962, Buckminster Fuller presented the particularly audacious proposal for the Geoscope. It was a 200-foot diameter geodesic sphere to be suspended over the East River in New York City, in full view of the United Nations. It was a big idea, for sure, and it was one that he felt could truly inform and deeply affect the decision making of this body through animations of global data, trends and other information regarding the globe, on this sphere. And today, 45 years later, we clearly have no less need for this kind of clarity and perspective, but what we do have is improved technology.
Godine 1962, Bakminster Fuler predstavio je naročito odvažan predlog Geoskopa. To je bila geodetska sfera prečnika 60 metara koja bi visila nad rekom Ist u Njujorku, ispred Ujedinjenih nacija. To je svakako bila velika ideja, i mislio je da bi ona mogla da informiše i duboko utiče na odluke ovog tela kroz animacije globalnih podataka, trendova, i drugih informacija koje se tiču zemlje, sve na ovoj sferi. Danas, 45 godina kasnije, postoji jednaka potreba za ovakvom jasnoćom i perspektivom, ali imamo poboljšanu tehnologiju.
Today we don't need one million light bulbs to create a spherical display. We can use LEDs. LEDs are smaller, they're cheaper, they're longer lasting, they're more efficient. Most importantly for this, they're faster. And this speed, combined with today's high-performance micro-controllers, allows us to actually simulate, in this piece, over 17,000 LEDs -- using just 64. And the way this happens is through the phenomenon of persistence of vision. But as this ring rotates at about 1,700 rpm -- that's 28 times per second. The equator's speed is actually about 60 miles per hour. There are four on-board micro-controllers that, each time this ring rotates it, as it passes the rear of the display, it picks up a position signal. And from that, the on-board micro-controllers can extrapolate the position of the ring at all points around the revolution and display arbitrary bitmap images and animations.
Danas nam nije potrebno milion sijalica da napravimo sferični displej. Možemo koristiti LED sijalice. LED sijalice su manje, jeftinije, duže traju i efikasnije su. Najbitnije za nas je to što su brže. Ova brzina, u kombinaciji sa današnjim mikrokontrolerima visokih performansi, dozvoljava nam da na ovom delu simuliramo preko 17 000 LED sijalica, koristeći samo 64. Ovo se dešava kroz pojavu koja se naziva istrajnost vida. Ovaj krug okreće se na oko 1700 obrtaja - to je 28 puta u sekundi. Brzina ekvatora je zapravo oko 100 kilometara na sat. Na uređaju postoje 4 mikrokontrolera koji, svaki put kada se ovaj prsten okrene, kada on prođe zadnji deo displeja, dobija signal o poziciji. Mikrokontroleri na uređaju mogu da izvuku položaj prstena u svim tačkama u toku okretanja i da pokažu arbitrarne slike i animacije.
But this is really just the beginning. In addition to higher resolution versions of this display, my father and I are working on a new patent-pending design for a fully volumetric display using the same phenomenon. It achieves this by rotating LEDs about two axes. So as you can see here, this is a, eleven-inch diameter circuit board. These blocks represent LEDs. And so you could see that as this disc rotates about this axis, it will create a disc of light that we can control. That's nothing new: that's a propeller clock; that's the rims that you can buy for your car. But what is new is that, when we rotate this disc about this axis, this disc of light actually becomes a sphere of light. And so we can control that with micro-controllers and create a fully volumetric, three-dimensional display with just 256 LEDs.
Ali ovo je samo početak. Pored verzija ovog displeja sa većom rezolucijom, moj otac i ja radimo na novom dizajnu za koji sledi patent sa potpuno volumetrijskim displejom koji koristi istu ovu pojavu. Ovo se postiže tako što se LED sijalice okreću oko dve ose. Kao što možete ovde videti, ovo je strujno kolo prečnika 27cm. Ovi blokovi predstavljaju LED sijalice. Možete videti da se ovaj disk okreće oko ove ose, stvoriće disk svetlosti koji možemo da kontrolišemo. To nije ništa novo - to je "propeler" sat, to su felne koje možete kupiti za svoj automobil. Ali novo je to da kada ovaj disk obrnemo oko ove ose, disk svetlosti zapravo postaje sfera svetlosti. I to možemo kontrolisati uz pomoć mikrokontrolera i stvoriti potpuno volumetrijski, 3D displej uz samo 256 LED sijalica.
Now this piece is currently in process -- due out in May -- but what we've done is we've put together a small demo, just to show the geometric translation of points into a sphere. I've got a little video to show you, but keep in mind that this is with no electronic control, and this is also with only four LEDs. This is actually only about 1.5 percent of what the final display will be in May. So, take a look. And here you can see it's rotating about the vertical axis only, creating circles. And then, as the other axis kicks in, those actually blur into a volume. And the shutter speed of the camera actually makes it slightly less effective in this case.
Na ovome trenutno još radimo - treba da izađe u maju, ali napravili smo malu demonstraciju, kako bi pokazali geometrijski prelaz tačaka u sferu. Imam video za vas, ali imajte na umu da je ovo bez elektronske kontrole, i koristeći samo 4 LED sijalice. Ovo je zapravo samo 1,5% onoga kako će izgledati konačni displej u maju. Pogledajte. Ovde vidite da se okreće samo oko svoje vertikalne ose, praveći krugove. Onda nastupa druga osa i njih dve se stapaju u volumen. Brzina zatvarača na kameri u ovom slučaju to zapravo čini nešto manje efektivnim.
But this piece is due out in May. It'll be on display at the Interactive Telecommunications Spring Show in Greenwich Village in New York City -- that's open to the public, definitely invite you all to come and attend -- it's a fantastic show. There are hundreds of student innovators with fantastic projects. This piece, actually, will be on display down in the Sierra Simulcast Lounge in the breaks between now and the end of the show. So I'd love to talk to you all, and invite you to come down and take a closer look. It's an honor to be here. Thanks very much.
Ali ovo treba da izađe u maju. Biće postavljeno na Prolećnoj izložbi interaktivnih telekomunikacija u Grinič Vilidžu u Njujorku, biće otvoreno za javnost, pozivam vas sve da dođete i posetite je, to je fantastična izložba. Tu je stotine studenata inovatora sa fantastičnim projektima. Ovo delo će zapravo biti postavljeno u sali Sijera simulkast u pauzama između početka i kraja izložbe. Voleo bih da popričam sa svima vama i da vas pozovem da dođete i pogledate za sebe. Čast je biti ovde. Mnogo vam hvala.
