David;
There was a lengthy thread about this portable darkroom box project over on F295,
here. Unfortunately, the attached pictures in the thread have since become lost after forum software upgrades, and so I'll have to make a video about the box in the near future.
The project started from my interest in portable camera/darkroom boxes used by street photographers in places like India and Afghanistan, used to make B/W portraits. But instead of building a camera into the side of a processing box, I wanted to have the box separate.
One thing my box lacks is a red viewing window in the top lid, which precludes me from developing by inspection. Perhaps in the future I'll get around to upgrading the design.
