    Lushprojects business card

    A lot of people ask me about the above photo which appears on the Lushprojects business card. Here is the original description:

    Palmer, Alfred T.,, photographer.

    This girl in a glass house is putting finishing touches on the bombardier nose section of a B-17F navy bomber, Long Beach, Calif. She’s one of many capable women workers in the Douglas Aircraft Company plant. Better known as the “Flying Fortress,” the B-17F is a later model of the B-17 which distinguished itself in action in the South Pacific, over Germany and elsewhere. It is a long range, high altitude heavy bomber, with a crew of seven to nine men, and with armament sufficient to defend itself on daylight missions

    1942 Oct.

    It’s from the US Library of Congress collection on Flicker.

    The series is visually beautiful and must have been originally created as propaganda tools. I like its enigmatic quality if taken out of context.

  • Extra bends on GSC AVEP2S

    Posted on March 23rd, 2010 Iain No comments

    The circuit-bent AVEP2S is still my favourite video tool. I was looking at some other video circuit benders work and liked a lot of stuff they were doing with chroma keys and control of saturation in an image. This inspired me to go back to the AVEP2S and add a few other nice features.

    The first project was to add some simple chroma key functions. The signals that were easily available to do this are the PAL colour components “(R-Y)” and “(B-Y)” so they aren’t real chroma keys because there is a big component of luminance in them too. Still they help slice up the image. The keying circuit is built from a uA733 video amp (from the arc) to boost the signals feeding in to a comparator. I found the 733 amp really hard to work with – it seems very sensitive to DC biasing and impedance on the output. Any advice from readers on how to make effective use of this IC is welcome.

    The other mod was to provide an input that can override the manual colour saturation control so that output can be varied dynamically.

    With the additional keys you can get some really nice effects – particularly as you can modulate the key with an audio signal.
