    I have instructions from Bob/red pepper, but I have not tried them yet.

    @jakerye I'd be glad to walk you through it this afternoon.

    I think I'm going to redo these measurements and also test the minimum dosage (which will be a bit hard but we shall see)

    @jakerye
    Thanks @Spaghet!

    @sp4ghet
    what would you say is the minimum required dosage accuracy for the minimum dosage?
    ±1ml/min?
    I'm sure the smallest dose we can get is just like 1 drop, but getting 1 drop and not 2 drops every time will be hard

    That’s the recommended feed chart for the nutrients
    So somehow we need to make that achievable in a realiable way. Dilution of nutrients is not out of the question either
    Rikuo Hasegawa
    @sp4ghet
    That's 10 ml per day?
    10 ml/1gal
    damn imperials
    Jake Rye
    @jakerye
    the smallest increment in 2.5ml/gal/week

    week...
    woah

    @jakerye
    of dua a/b, but some of the other supplements are ml
    *1 ml
    Rikuo Hasegawa
    @sp4ghet
    We may have a problem lol
    We should probably dilute tbh
    Jake Rye
    @jakerye
    agreed

    @sp4ghet
    I will test the pumps again since I now have better measurement tools courtesy of arielle
    Jake Rye
    @jakerye
    as long as we set a spec that is reliable we can work with that. 10ml +/-1ml would probably be fine
    also somewhat unrelated. does usb cam node crash on the ML bot?
    Rikuo Hasegawa
    @sp4ghet
    yeah..
    I think so
    We usually get Error 19 no such device /dev/video0

    @rbaynes
    yes, @jakerye video / usb cam crashes. I’m working on that too
    Jake Rye
    @jakerye

    Rob Baynes
    @rbaynes

    we have first friday lunch soon, jake, if we are non-responsive when you return, that is why

    @jakerye
    ok thanks for the heads up. sorry to bail. got sucked into compiling some documents….
    Rikuo Hasegawa
    @sp4ghet
    @jakerye I got 2.25ml/min at a accuracy of about 0.25ml
    I don't think it can get much smaller
    Anything past 40 stays super stable
    I will experiment with stuff inbetween 40 and 2 but it seems fairly linear
    blob
    each test is ml/min at MAX/HALF/0.02 "duty cycle"
