    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

    @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

    @jakerye
    do you guys want to try out a quick standup this morning?
    Rob Baynes
    @rbaynes
    as long as I can do it sitting down :) nobody but me here at the moment
    Jake Rye
    @jakerye
    i think we can accomodate haha
    just ping me when we have more friends show up
    Rob Baynes
    @rbaynes
    or at least Mr. @Spaghet

    @sp4ghet
    Hi
    Rob Baynes
    @rbaynes
    @jakerye @Spaghet we can do a standup anytime
    Rikuo Hasegawa
    @sp4ghet
    ditto
    Rob Baynes
    @rbaynes
    one sec, let me find a room
    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"
    I think we should dilute to around 100x or even 1000x to get stable

    @rbaynes
    Nice job @Spaghet ! I suggest you write up this in the wiki as a formal “pump test/calibration procedure”. After you have a few more data points, we can do the same test on another bot to see if they are the same.

    Hi everyone, Firstly thanks to those who have shown their support for the Digital Farm Lab! It means a lot to us.
    I have a question about the brain. A few of us in the community have been working with it but, as you know, it's going through some changes now. I'm wondering how we should move forward with working with the brain? Should we hold off? Is there a version that we can put together?

    @WebbPeter

    We finished building two V2 kits from Fenome about two months ago here in STL. I have not yet been able to install from docker and flash successfully (the consensus on the forums at least is that that isn't currently working)? I have gotten a successful source install and launch of the brain about a month ago following Juhnke's documentation on the forums, but was unable to ever connect to the UI or view the webcam. I've been trying for the last month to get an install unsuccessfully.

    I definitely want to second @AdrianLLu's question: should I just hold off on trying to run the brain? In addition, it sounds like the decision is to move away from the current Pi/Arduino hardware, so I'm a little concerned the V2.01 release won't even work with our current kits.

    Hi @WebbPeter and @AdrianLLu, the brain software has had some major changes to fix the critical issues we were having with it (arduino serial communication, dosing pump accuracy and a lot of other issues related to those two). We are in the final testing phase next week, then we start our own validation test grows the following week. If all goes well, I will put out a topic on the forum covering the details, release notes and how to upgrade to the latest software. The V2.x hardware has not changed, we are still using the raspberry pi and arduino, exactly as documented. Sorry for the lack of communication, the (small) full time software team has been heads down for the past 6 weeks trying to solve all the issues.
