Would you mind sharing your case design files with the rest of the community?
Cool. GFCI isn't an option for me (I rent) and my kitch and bathroom are all on the same circuit, but this doesn't seem like a big deal. My current STC-1000 setup has no fuse and has never given me any issues.1. Your house should have breakers in the main panel. If your concerned about anything then use a gfi.
Yeah, that's what I was linking in #3. Just wanted to make sure the LCD panel I was linking would also work.2. Look into the brewpi with lcd forum that day_tripper started up.
3. Probably as long as it's the same hd44... Blah blah whatever chip
Ah, is this because the Arduino pulls more power? I thought I read it was pulling .4A, but I wasn't sure, hence the question.4. If the fan pulls 1.6A I don't think it's a good idea. Try using a 3 amp or higher.
Yeah, found the answer to that shortly after posting. :smack:5. Not really. At least not yet. And this has been answered.
I have read a bunch over at community.brewpi.com but not posted there yet. As for the power supplies, I was not concerned with it taking up an extra receptacle b/c I wanted to add one anyway.You can get pretty cheap 12v power supplies on Amazon and eBay that can be wired in instead of adding more bulk with the wall wart and extra receptacle.
Have you been to the community.brewpi.com forums with any of your problems?
2) I'd like to wire some different colored LEDs to the project box that can indicate whether the unit is heating/cooling.[...]
Thanks day_trippr! I totally had to google the terms in your 1st paragraph, but thankfully I understood enough to parse out the 2nd paragraph and got it working!The AVR can handle the LED in series with the optocoupler used on most relay modules plus a second LED in parallel. I've done this on my Bluetooth BrewPi minions as you can't see the relay module inside the box.
Star the connection from the UNO, send one copy to the relay module as usual and the other to the cathode of your added LED. Then connect the anode through a 200-300 ohm resistor to 3.3V or 5V (whichever you have handy) and you should be good to go...
Cheers!
I found this on Amazon, it is a 8 relay version of the board you used. Can the Arduino support 8 relays? this would be a great way to have multiple chambers with one controller. http://www.amazon.ca/SainSmart-8-CH-8-Channel-Relay-Module/dp/B0057OC5WK/ref=pd_bxgy_422_img_y
Ummm....
Nope.
Cheers! (I'm sure that was joke anyway )
Umm yep. What you think I've been doing with all those arduinos
[...]For two days now I have been testing it with a carboy that has a thermowell and I have the water lock in there to recreate how I will ferment. After a day of the temp going from 3 degrees above to 3 degrees below my set beer temp, it has changed to going from my set beer temp and 3 degrees below my set temp. Do I need to get a heater for it? What does the community recommend? Thanks in advance
Is the thermowell sitting in beer, water - or air?
If there's any thermal mass at all I would expect the regulation to be much tighter than 3 degrees. As for the shift, the BrewPi control algorithm should be "learning" how to tighten up the regulation; perhaps it's getting there...
Cheers!
Running multiple independent heat belts inside your one chamber.
Not sure anyone else does that...
Cheers!
Its sitting in 5.5 gallons of water. I was hoping to brew tomorrow since I haven't been able to brew in about two months due to not being able to control ferm temps. I realize it may take more than 2 days to adjust
hi there!
The brewpi docs site is not working! They changed the domain?
Thank you
Other question, i can use a RTD Pt100 has a sensor?
Thank you
thank you for your help!
Btw the docs are working now! I will buy a new prob
Yea i'd just use DS18B20 probes, you can buy a bundle of 5 prewired for like $15 on Amazon.
EDIT: Followed the "sudo adduser pi" command and got it to work.
Hi all,
Tried to install Brewpi. Towards the end of installation I got the message "Usermod: user 'pi' does not exist." Any explanation?
Here's my status that might give some hints.
Waiting for my arduino and relay to arrive in the mail. Decided to try to set an old PC. Saw people said that they used Ubuntu, so I downloaded and installed it. Connected to ethernet and ran the update script sggested as first step on manual page here (http://docs.brewpi.com/manual-brewpi-install/webserver-setup.html). Then I installed git and cloned the Brewpi toolbox from github (http://docs.brewpi.com/automated-brewpi-install/automated-brewpi-install.html). Started the install and got to where I had the error. I searched the first part(http://docs.brewpi.com/installing-your-pi/rpi-setup.html) and it mentions user 'pi' password 'raspberry'. Is the username I was supposed to use? Is it the username I should have used for Ubuntu?
Thanks for any help!
Thanks for the info. I decided to skip over setting up WiFi and static IP, so I might just go back and reinstall everything in the correct order this time. I'll also probably just make the user pi.
Might try just installing Debian too since this is a super old computer. Minimizing a window takes ~4 seconds and I can watch the program shrink... Based on your description, Debian is the non-GUI version of Ubuntu? Think that would consume less power once I'm up and running with Brewpi?
Guess I spoke too soon. Downloaded git and got the files installed from GitHub. install.sh worked fine. It finished with "Happy Brewing". However, I can't get on the web interface now. It said go to IP address in the browser. Didn't work. I also tried https://brewpi like Fuzzewuzze said in the first page. That didn't work either.
Do I need a static IP for this? Should regular wifi work too? I tried to fix IP address outside of DHCP but screwed up. No internet access, so I reset the etc/network/interfaces. Just regular Wifi now (dynamic IP, I assume). I think I could have messed up that aspect. If I need a static IP, I can look more into that.
Might as well ask a few more related to that
Ran ifconfig (while on regular WiFi) and for the "wlan0" section, I got inet address 192.168.0.104 Bcast: 192.168.0.255 Mask 255.255.255.0
Opened my router in browser. The WAN on that page lists different IP Address, Subnet Mask, and Default Gateway than used by ifconfig.
I did click on DHCP tab and those IP start and end addresses are similar to ifconfig values. 192.168.0.100 to 192.168.0.199. The default gateway is 192.168.0.1.
So what do I set for values in interfaces section? What's the Bcast?
And last dumb one, it says wpa-ssid "YOUR_SSID". What is the actual format? No quotation marks actually needed? My SSID is two words with a space. Should I use the _ for a space? I figure linux might interpret as two commands.
Any help is appreciated!
Try http://192.168.0.104 in your browser, assuming your system still has that Wifi IP address. If thats not working then the system isnt really up and functioning...
If your on the raspi using the browser type localhost into the address bar and hit enter.
Did that and didn't work. Poor wording on my part. " It said go to IP address in the browser." Any ideas where I might have gone wrong? It doesn't need to be hooked up to Arduino to load in browser, does it?
He's on a desktop, not an RPi. Which leads me to...
Did you let the install.sh put files in the default directory? BrewPi puts things in /var/www but newer Linux distros (or Apache builds) have switched to using /var/www/html for the document root. Try this:
ls /var/www
If there is an /html directory than that's the problem. You can copy all of the brewpi files into that /html directory or run the script again and put the files where you want.
What do you see when you go to http://localhost on the machine? If you see an Apache welcome page that confirms my theory. If you get something else then I'm probably wrong.
Raspbian still uses /var/www I believe.
Just went away for the weekend. That sounds like it could be the fix. I'll definitely try when I get back.
I tried to find the /var directory before. Didn't see it in the home directory though. Is that where it's located?
- I am running 1 instance of Brewpi with RPints on a RPi2, wired to ethernet. RPints is in /var/www and Brewpi is in /var/www/brewpi, which is how I set it up through the automated install (installing RPints 1st). I would prefer it this way too since I plan to open it up to remote access from work using a login for the Brewpi (and thankfully RPints comes with built in admin security).
- The script starts at the initial boot fine and the CRON job seems to be working fine. If I stop the script from the Web UI, it stops and creates the "brewpi do not run" file in /var/www (that may not be the exact file name, because I'm typing this from my phone away from home, but that is the right location). It is owned by user brewpi and group www-data. However, if I click the start script button on the Web UI, nothing happens and the "brewpi do not run" file remains in /var/www . If I manually remove the file via the command line, CRON catches it, and the brewpi starts back up normally.
- So how do I get the script on/off button to work correctly from the Web UI? Is this not working because the button expects the index.php and the "brewpi do not run" files to be in the same directory? I've seen plenty of posts indicating others run brewpi outside of /var/www and it seems to be working for them. Do I need to edit a file to tell it the real path? When I initially installed brewpi, I told it about the /var/www/brewpi location, I didn't move it there after. I have tried a fresh install of everything (reformatted another microSD card and started from scratch), but continue to have this problem.
