    I'd say you haven't merged the .rosinstall and run downloaded the source code for image_view/dynamic reconfigure
    If you don't want to read into how ROS installs things work I'd suggest doing fresh reinstalls

    @rwdavis513
    I tried this... wstool merge -t ~/catkin_ws/src --merge-replace ./image_view.rosinstall

    @sp4ghet
    wstool update -t ~/catkin_ws/src --delete-changed-uris

    I'd be glad to learn, but the docs aren't very clear or haven't found the right ones to read.

    Gordon did a good writeup on ROS's install/build process in the wiki
    or you can peek into openag_brain/scripts/init_dev
    image_view is already a dependency under the develop branch so it should install cleanly on a fresh reinstall

    @Spaghet One more question, were you able to get image_saver to work? I'm getting this error:
    rosrun image_view image_saver image:=/usb_cam/image_raw
    Couldn't find executable named image_saver below /home/pi/catkin_ws/src/image_view
    Rikuo Hasegawa
    @sp4ghet
    I don't get that error
    I usually get a permission denied error on /var/www/html/img.jpg

    Hey @jakerye I'm getting this weird behaviour from the relay where I will pull D28 or D29 down on the Arduino and this makes relay K15 and K16 both turn on
    Any tips?
    Rikuo Hasegawa
    @sp4ghet
    It works without the signal board
    I may have soldered the 2 connections together...
    woops
    That looks to be the problem :/

    hey @rwdavis513, @rbaynes, and @Spaghet I just got the artisan bot up and running on the develop branch. I want to connect it to the cloud ui, is this something I can do yet?
    Rob Baynes
    @rbaynes
    I have instructions from Bob/red pepper, but I have not tried them yet.

    @rwdavis513
    @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)
    Jake Rye
    @jakerye
    Thanks @Spaghet!
    Rikuo Hasegawa
    @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
    Rikuo Hasegawa
    @sp4ghet
    week...
    woah
    Jake Rye
    @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
    Rikuo Hasegawa
    @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

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