    small-tank processing device for automated tilting and chemistries exchange

    A fellow from Germany built himself such device:

    (video included)

    Keep in mind that the device does not invert but just tilt the tank.

    Quite interesting. Servo seems to have enough snap to achieve pumping of the fluid across the film surface on each rock. as long as there is sufficient change of chemistry at the emulsion surface and it is even for the full length... its a wonder. Very cool.

    I think that the Japanese have a word for this:

    The device is very creative and obviously took a lot of work to create. However, doing small tank development by hand seems much more efficient for a number of reasons.

    I think so too, but nevertheless there is this commercial inverting device:

    in motion:

    This device not only inverts but in addition rotates the tank.

    To me the most surprising feature of that DIY device is the low agitation.

    Interesting devices. Personally though I prefer to be more involved in the process. After all, that's why I'm still into film.
    WYSIWYG - At least that's my goal.

    AGX, if you are doing hand inversion, or agitation, then many people will only agitate for 10 seconds +- every minute and that has been successful for about a century, give or take.

    If you have been using a Jobo rotary processor as I have, then it does look a little low on the agitation, but whenever I hand develop, I do it at one minute intervals, doesn't seem to make much difference if you adjust your developing times accordingly.

    Thanks for the link, very good.

    I did not think of the agitation sequence but the agitation amplitude: that tilting of the tank against the inversion of the tank

    Aah, point taken, yes I did look closely at that, but concluded it would work.

    I thought about rotary processing, whereby the film is out of the developer for about 45% of the time.

    "Amplitude", word of the day, nice choice of word there.
