Nueva Unicicleta… Incómoda, pero divertida!
Get your skates on with the FlyRad motorized unicycle

The FlyRad motorized electric unicycle
Image Gallery (8 images)
We’ve seen a few vehicle designs that have had a crack at bringing the unicycle out of the circus and onto the street, such as the self-balancing eniCycle, the UnoMoto, the EMBRIO and Honda’s U3-X. Here's a very different approach. Although it is a one wheeled motorized vehicle, there's nothing self-balancing about the FlyRad – the design requires the rider to wear a pair of inline skates while they sit, stand or simply get dragged along in a way that reminds us of the Zap Powerski.
Invented about six years ago by Thomas Rank, the latest edition of the FlyRad comes in three sizes: one for adults, one for teens and one for children. The currently configured adult model is fitted with a 500W motor powered by a 36v battery. It weighs about 24 kg (53 lb) and can reach a maximum speed of about 40 km/h (25 mph), traveling about 50 km (31 miles) on a single four hour charge. It can also be fitted with a 1,000W motor and stronger batteries for those looking for an bit of extra oomph.
Users can “ride” the vehicle in a number of ways including sitting, standing, squatting or hands free. Riders can even switch positions on the go. In standing mode the device is held much like a jackhammer which tows the rider along, while in sitting mode the rider sits on the saddle with a pair of skates acting as the vehicle’s front wheels.
Since steering is controlled by the skates, the rider can let go of the handle bars altogether to give the sensation of flying that presumably gives the FlyRad its name. When ridden in this way the FlyRad stays in place by transferring the rider’s weight onto a couple of pads attached to the bottom of the handlebars that push down onto the rider’s upper legs.
Designed as a form of environmentally friendly transportation as well as for fun and extreme sports, the FlyRad took a silver medal at iENA 2010, the International Trade Fair for “Ideas-Inventions-New Products” held in Nuremburg in October.
The first FlyRad (German) is expected to be available in 2011 at a price yet to be announced.
¡¿Película sobre el Cubo Mágico?!
Confirmado: Se acaban las ideas! :P
Por Fernando Bogado
Ya lo habíamos advertido: es muy curioso cómo se está moviendo el mercado en la actualidad. Digo bien “el mercado” y no necesariamente “la industria del cine”, pero podemos pensar muy bien que los dos nombres pueden ser aplicados indiferentemente, aunque creo que es momento de realizar distinciones. La “industria cultural”, por extensión, “la industria cinematográfica”, tiene que ver con la producción efectiva de películas que mal o vienen mantienen la misma estructura y puede perfectamente ser sintetizada en las típicas películas de género: es un término que proviene del filósofo Theodor Adorno y tiene que ver con la caracterización de la producción del “arte masivo” frente al “arte”, en términos efectivos, quiero decir: a lo que Adorno consideraría el verdadero arte. ¿Qué le pasa a esta industria del género cuando recibimos la noticia de que se va a realizar una película sobre el Cubo Mágico o el también conocido Rubik´s Cube?
Aquí es donde creo que es pertinente realizar la distinción: la industria implica una determinada idea de producción, algo que si tuvieramos que buscar el equivalente en otro tipo de producciones tendríamos que registrar como la propia de la mercancía, de los bienes: un ejemplo tonto, pero una silla, una mesa o un paquete de cigarrillos son perfectamente ideas que pueden ilustrar lo que caracterizamos como industria y equiparamos con el cine de género, la industria cinematográfica. Ahora: este tipo de noticias nos puede muy bien colocar en otro momento de la producción de bienes masivos, es más, hasta tendríamos que descartar la idea de bienes… En vez de industria, creo que ideas como estas nos sirve para entender la idea de “mercado” del cine.
Vayamos por puntos: Jean Baudrillard, un sociólogo francés, propone en un libro que tiene como nombre El intercambio simbólico y la muerte. En ese texto, rescata que el tipo de producción de la actualidad está desprendida de la idea de un referente: por ejemplo, el dinero no obtiene su valor a partir de la referencia positiva a determinada cantidad de horas hombre de trabajo, sino que empieza a establecer relación negativa con otros tipos de dinero, lo que podríamos ver en la relación de las monedas ente sí dentro del mundo de las finanzas. El cine de género de la industria cultural tiene esta relación con el mundo cotidiano del espectador, esta secreta referencia mimética que busca hacernos creer que tal historia pudo realmente haber pasado —- quizás por eso el mejor cine de género hollywoodense sean las diversas Comedias Románticas que cada tanto vemos aparecer en la cartelera —-.
Ahora: ¿qué pasa con el mercado de cine? ¿Qué caracteríticas tienen esas películas que produce? Quizás esta noticia de que van a realizar tantas adaptaciones de juegos de mesa —- desde la tabla ouija hasta la batalla naval —- tenga que ver con el tipo de cine que en estos momentos está siendo producido, un cine donde ni siquiera la estructura de género cuenta, o mejor, esa misma estructura es reducida a su grado mínimo con el objetivo de priorizar otras características de la cinta, como puede llegar a ser la presencia de efectos especiales o elementos dentro del campo de la imagen que sorprendan por sí mismos.
Esto, claro, es una serie de acercamientos un tanto laterales a un problema efectivo. Quizás estos apuntes tengan que ser revisados, pero es verdad que existe un cambio de un estado de producción a otro. Y es más: las consecuencias del cambio se sienten en todos los niveles, tal como podemos leer en esta nota, en donde uno de los ejecutivos de Universal —- Ron Meyer —- ve su carrera puesta en peligro por una serie de decisiones de adaptación mal tomadas. ¿Quedará como un mártir de un mercado por venir o sera la prueba de que el concepto de industria prima por sobre la idea de sistemas sin relación con el referente?
Sea de una manera u otra, no creo que estas adaptaciones sean tan geniales como prometen. Sin embargo, prometo realizar un estudio un poco más certero acerca de la cuestión.

Nvidia estrena su línea 500
Sorpresivamente en estos días, salieron a la calle las 580 de Nvidia, versionadas por todos los fabricantes.
Acaso la línea 400, fué lanzada para ganar tiempo, mientras mejoraban sus características? Sería éste un caso de “rebranding inverso”? Habrán pagado algún canon a Saphire por haber copiado, ejem, desarrollado, un cooler tan “parecido” al Vapor-X?
Sea como sea, viva la competencia! Cuanta más haya, mejor para nosotros, los consumidores :)
Nvidia GeForce GTX 580 Review: The Real Fermi Arrives
Nvidia's GeForce GTX 580 is what the original should have been: quieter, full-featured, faster and more efficient.
When Nvidia launched the GTX 480 — code-named the GF100 — early this year, the new GPU proved to be something of a mixed bag. It was undeniably fast, but also crippled – every GTX 480 GPU shipped with a full functional unit disabled. Whether that was because of yield or power issues wasn't clear. Power clearly was a problem – Nvidia's flagship ran hot and loud.
Given the competition, Nvidia had to get Fermi out the door. Even before the original Fermi left the building, Nvidia's engineers were heads-down, respinning and reengineering the GF100. The result is the GF110. The new GPU is, as Emperor Palpatine might put it, "fully operational", with all functional units now enabled. Even with more transistors humming, the core clock speed's been pumped up from the original 700 MHz. Memory clocks are now 1GHz, up from the stock GTX 480's 924MHz.
Features
As you can see, power is down a bit, while the number of functional units and clock speeds are up.
The GF110's designers took some time to tweak the paths through the GPU to streamline data flows. They also tweaked a few features, increasing overall FP16 texture performance, among other things. In addition, the card itself now has a new cooling subsystem, including a redesigned fan and a vapor chamber (replacing the heat pipes in the GTX 480). Even the shroud surrounding the cooler has been revamped, with the fan recessed slightly and the rear edge beveled more, which increases airflow and cooling effectiveness in SLI setups when cards are mounted very close to each other.
The GTX 580 vapor chamber dissipates heat more efficiently than the old heat pipes on the GTX 480.
The overall result is less obtrusive fan noise under load. Nvidia estimates the acoustics to be about 5dBA down relative to the GTX 480 and even lower than the GTX 285. We noticed during our testing that the card is not only quieter, but the fan noise is at a different pitch, which is less annoying. This may be due to the fan redesign, which is more rigid due to a ring surrounding the fan blade structure.
The lack of heat pipes on the GTX 580 is clearly visible here.
The bigger, shallower bevel on the rear of the cooling shroud is part of the cooler redesign.
Performance
So what we have is a faster Fermi, with all the functional units enabled, some internal tweaks to the architecture, all quieter and cooler. So how does it really perform? We took anNvidia GTX 580 reference card and compared it to a stock GTX 480 from Asus, plus Radeon HD 5870, HD 5970 and the new Radeon HD 6870.
Note that the Radeon HD 5970 is a dual GPU card. While AMD's CrossFireX performance and support has improved considerably with recent driver releases, performance is still dependent on CrossFireX scaling. Also, the HD 5970 is twelve inches long, which makes it a nonstarter in many mid-tower cases. Also, the XFX Radeon HD 5870 XXX edition is overclocked a bit, 3% on the core clock and 8% on memory. Keep that in mind as we take a look at the results.
All tests were run at 1920x1200, with 4x AA enabled. Our test system consisted of a Core i7 975 at 3.3GHz, with 6GB of DDR3/1333 memory, running on an Asus P6X58D Premium motherboard, with a Seagate 7200.12 1TB drive, an LG Blu-ray ROM drive, a Corsair TX850w 850W PSU, and Windows 7 Ultimate 64-bit.
3DMark Vantage and Unigine Heaven
Let's take a quick perusal at a couple of synthetic benchmarks. We don't put much weight to these results, but it's interesting to check them out.
The 3DMark Vantage test was run at the highest quality "extreme" mode, which isn't particularly extreme by today's standards. While the Radeon HD 5970 edges out the GTX 580, this is the fastest score we've seen with a single GPU card on our test system.
We expected the GTX 580 to be what Nvidia likes to call a "tessellation monster", and if the Heaven 2.1 scores are any indication, it certainly is. What we also see here is a difference in philosophy on how to handle tessellation. AMD likes to focus their sweet spot for tessellation on 16-pixel triangles, so when you crank up Heaven's tessellation factor, it stretches the Radeon cards past that sweet spot. So Nvidia's cards come out on top.
But what we really care about is performance on real games. Let's first take a look at DirectX 10 performance, then.
DirectX 10 Gaming Performance
The games we tested for DX10 performance include Far Cry 2 (two different scenes), Just Cause 2 (the Concrete Jungle benchmark), Tom Clancy's HAWX and the aging, but still gorgeous, Crysis.
By this time, Crysis has been thoroughly studied and drivers optimized by the GPU manufacturers. Even so, the GTX 580 finally manages to best the XFX Radeon HD 5870, though the dual-GPU 5970 crushes Crysis. The HD 5970 also manages top scores in Just Cause 2.
The same can't be said for HAWX or either of the Far Cry 2 benches. The GTX 580 just edges out the dual GPU HD 5970 in these games. Note that the GTX 580 crushes the single GPU Radeons in all these tests. [For the full rundown of DX10 performance charts, headhere]
So the GTX 580 looks like a beast in DirectX 10. Now let's move on to DirectX 11 performance results.
DirectX 11 Gaming Performance
The DX11 games we tested are a mixed bag. Some, like the recently released Tom Clancy's HAWX 2 and Metro 2033, make heavy use of DX11 features. HAWX2, in particular, uses DX11 hardware tessellation very heavily. Others, like BattleForge, DiRT2, Aliens vs Predator or Call of Pripyat, use DX11 features a little more judiciously.
HAWX 2 uses tessellation in an extreme way, but the result is gorgeously rendered, near-photorealistic landscapes. Fermi's ability to tessellate and render down to very small meshes plays very well in this test.
Metro 2033 was also interesting, mostly because of how poorly the single GPU Radeon HD 5870 fared. This result was repeatable, and we're not quite sure what's going on, since the newer HD 6870 managed a reasonable, if low score.
In most of the rest of the benchmarks, the GTX 580 gave the dual GPU Radeon HD 5970 a run for its money, either winning outright or coming very close. [For the full rundown of DX11 performance charts, head here]
Power
So how much power does the card consume? Given Nvidia's specs, it should be close to the power consumption of the GTX 480. Here's what we found.
Yes, the GTX 580 continues Fermi's high power consumption, but at least it eats watts more politely and quietly. Performance per watt is higher, too, given the better benchmark results we've seen in our testing. Still, it's impressive how even the dual GPU Radeon HD 5970 uses less power under full load than the GTX 580.
Final Thoughts: the Price of Speed
As we've seen, Nvidia's GTX 580 is clearly the fastest single GPU card on the market today. Given that we're looking at an early reference sample, it's likely that we'll see factory overclocked cards emerge in the next several months, pushing performance up even further.
However, the price for this level of single GPU goodness is steep. Nvidia's suggested pricing for the GTX 580 is $499. As always happens when a new GPU arrives, we start to see price moves by the competition. Radeon HD 5870s are now down to under $350 (under $340 in some cases.) The Radeon HD 6870, which is just a little slower, but more efficient, than the HD 5870, is under $250.
Even the somewhat scarce Radeon HD 5970 is seeing price drops. You can pick up a Sapphire Radeon HD 5970 for $499, $469 after a $30 rebate. AMD also likes to refer to the HIS HD 5970, but that's listed as "deactivated" on Newegg. However, other HD 5970s remain either very expensive or unavailable. Really, AMD's real answer to the GF110, code-named Cayman, isn't out yet. The Radeon HD 5970 really isn't a mainstream card.
Of course, we don't know what the yields are on GF110 yet, or what availability will be. Cards from companies like eVGA and Asus will likely be slightly north of the $499 price point, at least initially.
On the other hand, the GTX 580 is still 10.5 inches long, so will fit in more modest cases than an HD 5970. Nvidia recommends a 600W PSU for a single GTX 580. Given what we've seen with our performance tests, you don't really need more than one card for a typical 1920x1200 or 1920x1080 display. But if you want three displays, particularly three displays coupled with Nvidia's 3D Vision stereoscopic 3D glasses, you'll want two – but the much more modestly priced GTX 470 might work just as well in those scenarios.
So Fermi—the real Fermi—has arrived. It's still pricey and power hungry, but quieter and performs much better. We're looking forward to checking out retail cards, but for now, the fully operational GTX 580 should delight gamers with deep pockets.

Cómo hacer fotografías con efecto Zooming
Por Rafa Puerta
El efecto ‘zooming’ es una técnica que consiste en hacer un barrido de distancias focales con el objetivo zoom de nuestra cám
ara mientras realizamos una fotografía con un tiempo de exposición medianamente largo.
Esto provoca una distorsión en el contorno de la fotografía con unas lineas convergentes que crean un efecto de movimiento hacia el centro del encuadre y que permiten transmitir desplazamiento, velocidad o simplemente centrar la atención del espectador.
Para llevar acabo este tipo de fotografías lo ideal es contar con la ayuda de un trípode, fundamentalmente, para evitar la trepidación, ya que según la velocidad de obturación que escojamos, el movimiento con el anillo del zoom tendrá que ser algo rápido y un poco brusco, lo que provocará un movimiento importante en la cámara y obtendremos una foto movida.
Es una técnica algo complicada de dominar, pero en cuanto te haces con ella, empieza a dar unos resultados muy divertidos y sorprendentes, pero por supuesto hay que practicarla mucho antes de obtener un resultado satisfactorio.Que no os desanime si los primeros intentos son imágenes confusas y borrosas, ¡eso es más que normal al principio!
Por supuesto, os animo como siempre a compartir vuestros resultados con nosotros en los comentarios y a enseñarnos vuestros logros.
