Schmiede das Eisen, solange es heiĂź ist

Dieses Bild habe ich vor (mindestens) 30 Jahren mal fĂĽr einen Zeitungsbericht gemacht und verwendet.

Es entstand im Freilichtmuseum #Detmold. Aber: die #Schmiede stand ursprünglich in #Godelheim im Kreis Höxter (wenn mein Gedächtnis mich nicht täuscht). Und der alte Schmied, der hier Zigarre rauchend den Hammer schwingt und das glühende Eisen singen lässt, hatte eben dort viele Jahrzehnte zuvor seine Lehre absolviert.

This 3.5mm Cable Distorts Signals, Hides Audio-Filtering Circuit

image

The Bose headphone plug in question, with reverse-engineered schematic of the filter overlaid.

[Avian]'s dad got a new ham radio transceiver with a 3.5 mm jack, and his pile-of-cables got him a headphone cable from Bose headphones. He built a DB9 to 3.5 mm adapter with that one - and it failed to let data through, outputting distorted garbage of a waveform instead. With a function generator and an oscilloscope, [Avian] plotted the frequency response of the cable, which turned out to be quite far from a straight line. What was up?

Taking the connector apart was a tricky job. A combination of blunt force and a nail polish remover soak didn't quite get them all the way, so [Avian] continued to apply blunt force and took the jack apart with minimal casualties. Turned out that there was more to the 3.5 mm plug indeed -- a whole PCB with a few resistors and capacitors, reverse-engineered into the schematic seen above.

Looks like Bose decided to tweak the audio characteristics of a specific pair of headphones, and an in-plug filter was, somehow, the most efficient solution. We probably shouldn't expect to see this often, but it bears keeping in mind: next time your repurposed 3.5 mm cable doesn't behave as expected, it would be prudent to do a capacitance test with your trusty meter or oscilloscope.

With how small MCUs have gotten, you can easily hide more than just a few capacitors! We don't often see circuits built into cables, but when we do, it's for malicious purposes.

Photographing Fog on Both Film and Digital

image

For photographers curious about using either film or digital to capture foggy landscape, Michael Shainblum has put together a video showing the behind-the-scenes of using both mediums with a telephoto lens.

Shainblum, a passionate landscape photographer and filmmaker, often switches between a wide-angle and a telephoto lens, depending on the subject at hand. He has shared in the past the different ways to use a telephoto lens for landscape work, such as when shooting minimalist scenes of sand dunes or when looking for compelling and unique shots in areas that have been photographed by many, such as Yosemite National Park.

This time, when Shainblum headed up the mountains to photograph the scenic views filled with fog, he took his Sony Alpha 1 with a Sigma 100-400mm zoom lens alongside a 35mm Nikon FE camera body loaded with a roll of Portra 400 film and also equipped with a telephoto lens.

The beauty (and the challenge) of photographing fog is that the scene in front of the camera continuously changes, revealing new opportunities for compositions. As the fog passes through the trees and as the light changes, no one frame will be the same as the previous one.

Similarly, a telephoto lens, if used from a good vantage point, gives numerous ways to capture the landscape, for example by zooming in on a pattern or a particular detail that a wide lens wouldn't reach.

When photographing in foggy conditions, photographers have the choice of shooting shorter exposures to capture the texture of the fog or opting for a longer one that blurs out and softens its movement. During his trip, Shainblum experimented with both and also added his film camera to the mix to capture the exact same scene with both cameras.

Although the results delivered from both digital and film are different, the subjective preference of the medium is down to the photographer themselves. All in all, for Shainblum, the experience of photographing fog can be therapeutic, whether it is shot with a film or digital camera.

In fact, although Shainblum usually has his camera with him, there are plenty of times where the soothing experience of simply watching the changing landscape can be more than enough.

More of Shainblum’s educational and inspirational videos can be viewed on his YouTube and his photographic and video work can be found on his website and Instagram.

Voici un nouveau tirage qui met un peu plus en lumière le travail des double expositions.
Vers quelle machine à rêve ces images entre-mêlées me mèneront-elles ?

Here is a new print of the double exposure work previously introduced.
Toward which dream machine these images will lead me to ?
