    Should the phone screen be a safelight colour?

    From the video, it looked like the screen used red and amber colors, appearing to be safe.

    With the phone set to the lowest brightness, the app seems to be paper safe as close as 12 inches or so but I haven't tested it rigorously yet. Even at the lowest brightness the buttons are easily visible in the darkroom so I have room to darken them some more if need be. If you wanted to be absolutely sure you could cover the screen with a red gel or simply flip the phone over on its face.

    Some day, maybe. This current project is going to keep me busy for some time.

    Version 1.1 of the app has been submitted to the Apple app store and is awaiting approval. It has a more fully paper-safe interface using only the color red since, with an RGB display, any color other than red will affect photographic paper to some degree if it is bright enough.

    You should not use any module that's platform-specific. Bad engineering policy.

    This should work with the new iPod touch, should it not? If the system works well I sure would not have an objection to buying a new Ipod for it and would do that rather than use my phone. My phone in the darkroom is not an attractive thought. I want "them" not be able to find me in "there"!
    To find the answers - question them!

    Must one have a phone to operate your lamp? Can it be wired to a traditional timer?
