    It's good to be here and I appreciate the update @rbaynes. I have been following this guide by Juhnke: http://forum.openag.media.mit.edu/t/fenome-food-computer-kit-build/1819/31?u=webb.peter but am now getting stuck flashing the Arduino. We are happy to help test alongside with our V2's by running a real grow, that being said is there a way to get around the serial comm problems in the meantime? If not we can just hold out on trying another install until you've finished your testing.

    Our latest code is on the “develop” branch of openag_brain. That is what we are testing and it will become the long term stable release once we are done.

    Happy to be here! Thanks for the update @rbaynes and no worries. I'm just looking to understand the timing. We'll take a look at the develop branch.

    Hey Guys! @WebbPeter invited me here, and its exciting to chat iwth you guys. I had built the PFC2.0 a few months back and we are working to open up the product for use with "residencies" here in NYC! Super cool stuff, and our first project is really exciting

    Hi @DNels113_twitter, sorry we have been quiet this week, we were all at a conference. Back to the lab next week!

    hey @rbaynes while testing the pfc ph loops out at bates i have noticed that every time after running a recipe to lower the ph (current value is 4, new setpoint is 3) the arduino bricks. any ideas?
    Rob Baynes
    @rbaynes
    well that isn’t good!
    while the arduino is in the bricked state, have you tried killing the brain, then connecting to the arduino from an interactive python shell?
    Jake Rye
    @jakerye
    agreed! haha, but setting the ph to 5 works as expected (e.g. the ph+ pump starts pulsing)
    Jake Rye
    @jakerye
    ^ i have not tried that yet
    Rob Baynes
    @rbaynes
    I suggest manually sending the arduino commands to play with what its response is to different pH commands
    Jake Rye
    @jakerye
    will do, thank you sir!
    Rob Baynes
    @rbaynes
    then maybe putting in some debug code to the src.ino sketch to send back a error message with debug help in it. that is how I try to figure out what is going on in arduino land
    feel free to make a GH issue and doc this too
    thank you for the help.
    I am currently running the “hotfix_arduino_handler_node_crash” branch of openag_brain for the test grow.
    you may want to start with that, since there are some other known issues with the AM2315 flaking out and causing the arduino to stop sending data.

    protip: you can actually send stuff over serial in pio device monitor -b 115200
    just type and hit enter

    @rbaynes
    muy bien @Spaghet

    I have internet now so I can finally start doing stuff :cry:

    How did you survive so long without internet?

    @rbaynes I'm not a github connoisseur, but I think if you make changes to the develop branch they should be automatically picked up by your PR, so you wouldn't have to re-make it
    Rob Baynes
    @rbaynes
    I will try that, @davoclavo, thanks. I just pushed a few minor changes to your PR and now I have to wait for @Spaghet to review them. He is in Japan (and I’m in Boston) so there is a bit of a time lag.
    David
    @davoclavo
    also, let me know if I can provide any help/debugging with the docker build!
    Rob Baynes
    @rbaynes
    Thanks @davoclavo, I’m finishing the testing today.

    Hi! I noticed that the UI was trying to fetch images from a url like http://10.0.0.12:80/../img.jpg - after digging through the UI code it seems it was set to that value because of a demo (OpenAgInitiative/openag_ui@a986714). Is there a reason to keep the images being fetched that way? (via nginx+ros image_saver)
    I assume there was a problem by fetching the images from the couchdb document attachments, but I haven't able to figure out the reason.
    Thanks!
    Rikuo Hasegawa
    @sp4ghet
    Heyo, that UI part is definitely a hack. The trouble I had was converting the database document to an image encoding that could be seen in the browser.
    I think we can use the most recent topic type view to fetch the most recent aerial_image file and then view it in the UI if we can view the couchdb document as an image
    David
    @davoclavo
    Cool, thanks for the explanation! I have been able to render image attachments properly on the browser, I wonder if it is because I am using a different camera (and image format) but perhaps something else also changed recently. Anyways, I think reverting those commits for the demo should be enough to get it back running (which would include fetching the latest image). I'll file a PR soon to fix it

    @rbaynes
    Thanks!

    It appears that the latest release of Raspian (Stretch) does not have couch db pre-built package for stretch yet. The install scripts dies when it tries to install couchdb (we first noticed this on MVP, but also now when trying to install on openag_brain.

    @rbaynes in your V2.1 release on the Wiki at the bottom of the page under Downloads you have a link to this file: https://github.com/OpenAgInitiative/openag_brain/releases/download/untagged-c9c4f8b8e8bb32840ec3/openag_brain_v1.0.0.tgz

    It is returning a 404 error not found, I'd like to try using your image if you could update that link please.

    Rob Baynes
    @rbaynes
    @WebbPeter thanks, I’ll fix the link
    fixed

    hi all, here Thieme from the Netherlands - I'm from the AstroPlant team which is a project we do with the European Space Agency. We talked with Rikuo and Rob yesterday. We may be posting some questions here and hope to contribute to OpenAg (although we currently have a different stack, we look for possibilities for collaboration).

    @hennis_twitter
    PS. we also are planning to open source all our designs, but we still need to figure out what direction we take (RPi, BeagleBone, Arduino yes.no)
    first question: what is the reasoning for not using the DFRobot EC / pH sensors?
    byebye!
    Rikuo Hasegawa
    @sp4ghet
    Not sure if @jakerye still lurks around but pinging him
    Rob Baynes
    @rbaynes
    The decision to switch from the DFRobot sensors to the Atlas ones predates Rikuo and I. I will ask the older team members and get back to you (will take a few days). Please remind me if I forget to post their reply.
