Future Works

Future Works - Ein Film über ArbeitU nás v Kocourkově řešíme jednu kravinu za druhou a ani si nestačíme uvědomovat, jak je s námi manipulováno a jakou z toho mají manipulátoři prdel a peníze na účtu. Nejsme v tom sami, naši post-socialističtí sousedé z bloku RVHP a Varšavské smouvy také. A zatím nám ujíždí vlak. Třeba vlak s palčivými otázkami vývoje pracovního trhu, spravedlivého odměňování zaměstnanců a manažerů, nahrazování práce lidí prací robotů atd. Co se třeba občas podívat za humna a aspoň na chvíli se zastavit a pozorovat, čím se zabývá ten vyspělý svět hned za naší západní hranicí? Celý příspěvek

Jak si správně vybrat LED žárovky a nebýt pak zklamaný

Jak si správně vybrat LED žárovky a nebýt pak zklamaný

Není totiž LED žárovka jako LED žárovka. Některé svítí jen bodově, jiné umí osvítit celý prostor. Různé jsou i patice a liší se i samotná kvalita žárovek. A je jasné, že ne všude se LED žárovka vyplatí. Ve sklepě nebo ve spíži je lepší žárovka obyčejná.

Světelné diody jsou především směrové světelné zdroje, tudíž jsou velmi vhodné náhrady reflektorových žárovek. Máte-li v podhledu či v nábytku 12V reflektorové žárovky s paticí GU5.3/G4 nebo reflektorové žárovky na síťové napětí s paticí GU10, vyměňte je za směrové světelné diody, tzv. LED spoty. Pokud s těmito žárovkami alespoň někdy svítíte, náhrada se vyplatí. Celý článek

Výborný nápad jak rekonstruovat staré filmy

Výborný nápad jak rekonstruovat staré filmy

Old films may be nostalgic but they also play a significant role in cultural preservation. Digitizing them however, can cost thousands of dollars so a New York designer has developed an open source tool that makes transforming film affordable for anyone. Sharon Reich has more.

Kinograph, A DIY Digitizing Tool, May Be The Savior Of Film

Vinegar syndrome reeks of chemicals and the cooking ingredient it’s named after. The odor is the first sign of film decay. From there, the film base gets brittle, shrinkage occurs, liquid-filled bubbles appear, and in some cases, it bleeds pink or blue dyes. Calling this gory may be dramatic, but it’s a fundamental contributor to the irreparable loss of 90 percent of all American silent films and 50 percent of American sound films before 1950.

Part of the dilemma is that preserving film faces massive financial barriers–many institutions simply don’t have the resources to keep up. But under the belief that “history belongs to those who hack it,” artist and cinema historianMatthew Epler combats this with his invention, the Kinograph. Using a consumer-grade DSLR camera, materials available online, open source software, 3D printing, and no special skills, Epler has assembled a simple but sophisticated machine to digitize film that anyone could build.

The Kinograph currently requires $1200, if you already have the camera, but Epler has plans to get it under a grand. In comparison, the digital preservation cost for just one canister ballparks at $800, nevermind the shipping fees. The other alternative would be to purchase a digital motion picture scanner, which costs upwards of $175,000.

Epler crunched the numbers after discovering some 600 orphaned reels while teaching in Jordan. Russian, Arabic, Vietnamese, and English are scrawled on the films, many with seals from the USSR, some dating back as far as the 1920s. So, when King Hussein II of Jordan visited his school, Epler, having discovered that he had a reel of the king’s dad asked for $10,000 to restore the film. He soon realized he should have asked for a bit more (c’mon, that’s toilet paper to a king), and after sending ten reels to a film lab in Germany, the money was gone.

Unfortunately, King Hussein forgot about the project as soon as he left, and there were 590 more canisters to go.  Frustrated by the lack of democratization in digitizing film, Epler was determined to find a cheap and easy way to preserve the world’s history with quality.

There have been other attempts to make a DIY film digitizer but most involved either tedious hand-scanning of negatives or rigging an old projector to play the film while the images are captured. In addition to being difficult to find, the problem with projectors is their use of intermittent motion, a mechanism that inserts hooks into the sprocket holes starting and stopping the reel at each frame. This movement just happens so fast the viewer sees the images as a moving image, like a flip book. Imperfectly, this puts stress on the film and can lead to breakage. Many professional film scanners and telecines (machine that converts motion picture to video) use continuous movement to advance the film and a high quality sensor that perpetually scans the image either line-by-line or pixel-by-pixel. Regrettably, this goes beyond the capabilities of an SLR camera.

Epler’s answer combines parts of both approaches, along with 3D printing a specially-designed roller and buying a two-dollar switch. Essentially, with a continuous feed, the roller uses its strategically-placed bumps to trigger the switch at the start of each frame. This then signals the shutter to take a picture captured frame-by-frame. As a bonus, these 3D printed rollers can handle 8mm, 16mm, and 35mm film without having to be changed out.

In just four months, Epler impressively came up with the described design and prototype, but his vision does not end there. He’s always believed in the power of shared knowledge and its access. When he first found the garage full of canisters, he photographed each of the labels and posted them onto afilmarchive.net welcoming people around the world to translate them.

Accordingly, he hopes to inspire a community-driven effort to preserve film by supplying the Kinograph blueprints for anyone to create a film-digitizing studio, or at least eliminate the financial barrier for them to use one.

Anti-gravity 3D printing – video

Anti-gravity 3D printing – video

Mataerial, a collaborative project between Institute for Advanced Architecture of Catalonia and the Joris Laarman Studio, is pioneering a patent-pending 3D printing method it calls anti-gravity object modelling. Researchers claim ‚this new out-of-the-box printing method can help manufacture structures of almost any size and shape‘. This video is three times the normal speed
