OpenAg™ Personal Food Computer v2.0 (beta) [Documentation Release]


#22

Has anyone suggested simulating wind conditions? Maybe shaking based on a wind profile that includes things like duration and intensity would produce the desired effects. I recently read that an industry veteran in hydroponics (Christian?) still thought that LED grown plants were sickly compared to natural light grown ones. It lead me to wonder if the wind adds to the overall health of the plant and if we’re looking in the wrong direction when we blame the lighting.

Thanks for the hard work!

I think there is a part missing from the BOM—there are lines for the pH/EC probes themselves and the EZO circuits but reading the EZO circuit documentation some kind of EZO carrier board (and plug in which to plug in the probes) is also necessary. I assume it’s this https://www.atlas-scientific.com/store.html#!/Electrically-Isolated-EZO™-Carrier-Board-ISCCB/p/70295131 ? apologies if I missed it on the BOM, but I don’t think it’s there. @jake @gordonb @tim

It’s built into the signal board :slight_smile:


#25

how about your user-friendly guide now ?
Now,I am beginning to build my mini PFC.
I am waiting your guide!


#26

Be patient my friend!!! I’m waiting the PFC 2.0 one year now and finally we are at pre-release version… i hope that master release don’t take long :slight_smile:


#27

ok,When you’re finished remember to tell me.
In fact, I have not used Raspberry Pi, so I do not understand the working principle of PFC.
And Nutrient solution supply and water circulation system.


#28

I am also trying to scale up the design of the PFC. Have you scaled up your design yet? I would love to start a conversation about what specifically must be changed to account for the increased size of the bath/ frame, and would love any advice you have! Thank you!


#29

What have you all been using for LED lights?


#30

Food Servers:
Scale up conversation thread
Food Server Documentation

Lights:
Custom V2 Light
Foam Farm Lighting
DIY COB LED Lighting (My personal favorite)

Hope that helps, goodluck!


#31

Thanks a lot. Let see how this goes. :wrench:


#32

how much it costs to build a PFC…?


#33

Depends on where you live. You also can’t get every part yet (lights, chiller).

Here is a link to a post where they added prices to the BOM and came up with $2914.
You can buy a kit from this community member here and build it yourself for $4800 (no lights & chiller).
If you contribute $5000 to the Digital Farm Lab’s Kickstarter they will build you one (no lights & chiller).


#34

Roughly how long did it take to build a PFC?
