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

@rbaynes

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

Jake Rye

@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

Rikuo Hasegawa

@sp4ghet

Rob Baynes

@rbaynes

@jakerye @Spaghet we can do a standup anytime

Rikuo Hasegawa

@sp4ghet

ditto

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

Jake Rye

@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

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

Rob Baynes

@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

@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.

Rob Baynes

@rbaynes

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.

BY THE WAY: Welcome to the OpenAg chat channel! @AdrianLLu @WebbPeter

WebbPeter

@WebbPeter

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.

Rob Baynes

@rbaynes

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.

Adrian L. Lu

@AdrianLLu

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

Rob Baynes

@rbaynes

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