Taken on a small group of Islands in the Oslo fjord, called Hvasser. A 15 meter peice of fabric playing in the wind, scanned right to left in 21 seconds. Got really lucky with the clouds this time, allowing a single beam of sunlight in as a highlight.

    @Leavingoldhabits Hi again, I’ve started playing with an Arduino and a light sensor. At the moment all it can do is read the LED light source from the flatbed scanner during the calibration sequence, and record the results.

    The N650U has three stages of calibration:

    1. It starts with the LED fluctuating between ambient brightness (860) and full brightness (700), then turns off briefly (860)
    2. Steady increase from ambient to full brightness.
    3. Steady decrease from full brightness back to ambient.

    The next step will be to introduce some kind of timestamp for each moment of the recording. Then the hard bit will be to shine a light source onto the sensor so simulate a proper calibration.

    I haven’t recorded the calibration on the LiDe 110 yet, but I will. I didn’t realize it when I modified it, but the book says it will scan at 2400x4800dpi which works out to over 550mp for an A4 scan, which dwarfs the 20mp of my mirrorless, lol.
