HOWTO - Make a BrewPi Fermentation Controller For Cheap

dunz · Aug 17, 2014

Looking for a slightly higher amp rated mechanical relay. Would this work with the SainSmart UNO?

That dual relay module should work fine with an Arduino, they're both 5V devices...

Cheers!

Ok, you hooked me: where can you select the shield version? For all I know it's defaulting to the Rev A shield.

And is the only Build Events configuration that works the Active(Debug) version?

Excellent! What's your best guess what was wrong? I was thinking the cron.d instancing stuff...

Cheers!

I'll have to open her back up and take a look. I believe it's a config.h thing. I didn't use it like that and just changed the appropriate lines in defaultConfig.h or whatever it's called. But If I remember correctly u can choose which shield revision to build for towards the top of that file. I didn't look into that much. I just kept it as is. And I believe it's set to build for revc but don't quote me on that.

As for the multi instance problems I think it was a combination of some cron problems and the fact that I forgot that I needed pi user to join the other groups. After reading your walk through it jumped out at me as I had to do it when I built my vm with 1 arduino last time. Before I found that all I had to do to install on a non-pi was edit the install script to not run the raspberry pi update, which always killed the script on non-pi setups. After I get all this up and running I might look into building an install script that will build out up to 4 instances without the user having to go through all this.

Got my BrewPi setup done, using a Raspberry Pi, Arduino Uno and a PowerSwitch Tail II.

Why are my images sideways??

Is that panel mount usb connector from adafruit? I have bee trying to find a short one but seems like their 13" one is the shortest i can fine.

Thanks mongooseman! Used your how to and set a webcam up to spy on my brew in the shed Bought one of these. Ebay Mini Stylish USB 2.0 5M Meter Retractable Clip WebCam Web Camera Laptop SL item 301253251844. thanks!

Camera was low quality but good enough for this job. $3. Lead is only about 0.5m not 5 m

Then, in one of the folders (whichever you want), create a file called "multiLCD.html" (or whatever you want), and put the following code in it:

Code:

<html>
<body>
<iframe src="http://192.168.1.18/top1/lcd.php"></iframe>
<iframe src="http://192.168.1.18/top2/lcd.php"></iframe><br/>
<iframe src="http://192.168.1.18/bottom1/lcd.php"></iframe>
<iframe src="http://192.168.1.18/bottom2/lcd.php"></iframe>
</body>
</html>

Then, go to http://192.168.1.18/top1/multiLCD.html (assuming "top1" is the folder you put the multiLCD file in) and be happy with yourself

Should work...

thanks for all the help. i changed some code in the multilcd.html to remove scroll bars and make it work with dynamic ip should that ever be an issue. Couldnit have done the php work though so thanks again

I put the file in my root www folder
here is my multilcd code

Code:

<html>
<body>
<iframe src="../top1/lcd.php" scrolling="no" seamless="seamless"></iframe>
<iframe src="../top2/lcd.php" scrolling="no" seamless="seamless"></iframe><br/>

So in this setup all of the chambers are connected via a USB hub? or they just all go back to the computer running them?

whiskeyjax · Aug 20, 2014

Hey guys, I am having trouble getting brewpi to install.

When i try to run the install.sh file, it says there is nothing there, and it won't run from the graphic interface either,

Do I need to reclone the thing from GitHub?

Not a computer guy, but if you're talking about the following command.

sudo ~/brewpi-tools/install.sh

I would double check the spacing and spelling.
When I had problems it was one of those two things.

Good luck

whiskeyjax · Aug 20, 2014

I must've tried it 10 or 15 times, i wish I was sitting there with it right now. I'll try again tonight and post then. Thanks

Waiting on the hub to come in from amazon and a couple more temp probes. It'll be on a hub then. So I can have a mini keyboard hub and 5th uno for rpints. Till then I just have 2 hooked up for testing and a third setup running my fridge already. Once they get the multi ferment figured out it looks like I'll be able to dial this back to 2 arduinos and then I won't need the hub.

My guess is you cloned the directory in the wrong directory and not from the users home directory

day_trippr · Aug 20, 2014

WinSCP could fix that in seconds...

you can also try

locate install.sh

that should return all of the instances of install.sh on the machine and their full path. Then using the full path you can sun the script.

For example

locate install.sh
/usr/share/git/brew-pi/install.sh

then you can do

sudo /usr/share/git/brew-pi/install.sh

Hi all, I have my brewPi software running on my Rpi. However, I am unable to see my devices. I have 2 DS18D20 temperature sensors and they are wired exactly as the diagram shows. Listed are Device 0-4 none of which have the Arduino pin as A4. So there is not ones listed as device type temperature sensor. Is there a better way to test and see what is going on with my devices?

Do you have a 4.7k resistor inline between positive and the data (yellow) wire?

wbarber69 · Aug 21, 2014

Yellow is ground on mine.are u sure you have them wired correctly

RyanSweeney · Aug 21, 2014

Mine are Red = hot, Black = ground, Yellow = Data

wbarber69 · Aug 21, 2014

Mine are yellow= gnd red= 5v green= data

RyanSweeney · Aug 21, 2014

Ok, well the color of the wires aside, do you have a 4.7k resistor inline from the 3.3V (or 5V) to the data wire?

scoobyd63 · Aug 21, 2014

Mine are the same Red = vcc, black = ground, yellow = data.

I DO have the pull-up resistor in line.

RyanSweeney · Aug 21, 2014

Scooby, can you post a picture of your wiring?

I think the problem is that I don't have the data input going into the digital 4, but rather the analog 4 like the diagram in the initial post of this thread. So then where do the leads connect to the Sain Smart 2 channel relay?

Thanks a ton, I was mislead by the original connection.

RyanSweeney · Aug 21, 2014

I'm using the analog pin on my setup...works perfectly. I'm using Digital Pin 6 to send the signal to my PowerSwitch Tail (relay).

scoobyd63 · Aug 21, 2014

@ Ryan your wiring diagram shows it into the digital pin 4 though. I do have mine exactly the way they are laid out in the original diagram.

RyanSweeney · Aug 21, 2014

That's just a diagram I grabbed off google...my sensors data wires go to Analog Pin 4. I just used that diagram for reference for the pull up resistor.

scoobyd63 · Aug 21, 2014

Ah I see, I will grab a picture of wiring when I run home for lunch.
