All good! I'm flattered you incorporated it into your version.
That is probably the most practical way of doing it, but it does require some manual manipulation or record keeping.If you know all the values (empty keg weight, current keg weight, temp, pressure, altitude, and specific gravity), you could just retap it as long as you have the keg vlume kalculator mod installed, alternatively here's the Excel spreadsheet version:

Yeah, for starters your weight of water is probably based on the weight of water at sea level, also you need to adjust for the additional weight of beer versus water based on the final gravity of your beer, plus if the keg is pressurised you need to compensate for the weight of the disolved CO2 according to Henry's Law (which increases for lower gravity beers and decreases for higher gravity beers). Simple [emoji6]That is probably the most practical way of doing it, but it does require some manual manipulation or record keeping.
I started really caring about actual volumes of beer in the kegs since I got rpints running. Looking at your spreadsheet seems like just using the weight of water for estimating volume I was about a little over a half pint off for my normal beers.
I returned my first rpi and the replacement behaved the same as the first. I tried swapping the power supplies and it seems the losing wifi follows the power supply. I do get times when both seem to lose wifi at the same time so it might not just be the power supply for me, but whichever one is powered by the original power supply loses it more often.i was going to do an external usb wifi as my next move as i have good luck with one of those on another pi that is in a poor signal spot so it acts as like an external antenna. Good news is tonight on a hunch I took my pi off the keggerator hooked an hdmi tv to my pi and to my surprise lightning bolts on the display meaning low supply power.... i changed to a different micro usb cable and it went away and so far ive stayed connected... fingers crossed i found the culprit as it might have been a bad cable even though i changed to a more powerful 3 amp power supply.
Ran this script on a rpi3B with stretch, and I can get the Rpints display to work but no flowmonitor action.Try running this Script on the pi:
https://raw.githubusercontent.com/rtlindne/RaspberryPints/master/util/installRaspberryPints
simply download it to the pi and run
# i.e. "chmod +x installRaspberryPints"
# i.e. "sudo ./installRaspberryPints"
Ive made some updates to it in the past month that should make it work on the latest Stretch version
If I run the serial monitor in Arduino I can see the pulse messages
I will send you the file, but just wondering why you keep reflashing the uno?Did you enter a conversion amount on the taps screen?
Check /var/log/rpints.log if there is an exception or error in it, PM me the file an I will check it out.
to follow the log use the following command
tail -f /var/log/rpints.log
I will send you the file, but just wondering why you keep reflashing the uno?
Do you know which version you are running jessie or stretch?I apologize for the beginner question... I just joined this thread in an attempt to get my RaspberryPints working and have tried scanning through all 106 pages but still having issues.
I bought a kit off amazon with a Raspberry Pi 3 already loaded with Raspian software. I updated/upgraded as suggested. I can make it half way through Step 4 (no pumps) but can't get the LAMP software to load. I found another blog post that suggested:
sudo apt install apache2 phpmyadmin
However that keeps giving me error messages (2002 can't connect to local MySQL server through socket). After several hours of searching online I am no closer to figuring this out. Any advice? Or better yet, anyone have a functional SD card image that I could just etch on mine?
Thanks!!
Josh
Josh, here's how to get going:
I wrote a tutorial on how to get a Raspberry Pi working "Headless" but you can follow these instructions (with one difference) and use a Keyboard, Mouse and Monitor if you like:
Off With Her Head!
When it gets to the part about downloading a server image, instead of getting one of the Stretch images I link to, use this last official Jessie version from the raspberrypi.org website:
2017-07-05-raspbian-jessie.zip
The rest of the instructions should be fine for you. If you choose to use a keyboard/monitor/mouse, you can ignore the part about using "Headless Pi" to set up your networking. Just set the network up after you get booted.
I think the reason you had issues is you sorta mixed different paths (Noobs and a normal Raspbian image.) Noobs relies on a clean SD card, with one partition formatted with FAT. A Raspbian image creates a card with two partitions, one small FAT partition named "boot" and another partition using a Linux file system unreadable by most computers. These are both created automatically when you write the image to the SD card with something like balenaEtcher. After you run the setup from Noobs, it creates that two partition setup for you.
BY FAR I think balenaEtcher is the easiest way to go, since it does not care what used to be on your card. If you try to use Noobs on a card that was already configured as a RPi card, you will find you run out of space. Most Windows tools will not remove that Linux partition. You can do it manually, but since there's a tool that will do it for you (balenaEtcher), go with that.
Are there any key differences one should know about beforehand? If this has been adressed earlier I apologize for overlooking it.
Apologies to all for the testing delays, between the sustained extended work hours with my new job, and my birthday this past weekend, I've been spread a bit then.Code is modified. We're currently in the testing phase.
RandR+ - is your version for stretch? Can I try that one??
Nope!Josh did not explicitly say so, but t seems he has a 3B+, will you procedure work for loading jessie on a 3B+?
The StackExchange solutions seems solid. As you point out, getting a 3B would be needed no matter what apparently. That's a bummer.Josh, I found this about running jessie on a 3B+, seems like you need a 3B as well to load the appropriate drivers
https://raspberrypi.stackexchange.com/questions/81725/raspbian-8-on-raspberry-pi-3-b
When I bought my rpi I went with the 3B so I could run jessie.
sudo rpi-update ef7621d91cb58ccc856c3c17ddda28685edd23f3
sudo wget https://archive.raspberrypi.org/debian/pool/main/f/firmware-nonfree/firmware-brcm80211_20161130-3+rpt3_all.deb
sudo dpkg -i firmware-brcm80211_20161130-3+rpt3_all.deb

I downloaded the latest software (Stretch), booted up fine. I downloaded your script (using 2nd link). I then entered the two commands in your last post. The first one I assume worked. The second one loads fine but then I get an error because php5 and php5-mysql "is not available" and "has no installation candidate".
I searched the forum, found a post from you back in June that suggested "install libapache2-mod-php7.0 and php7.0-mysql" which I did. However I am still getting the same error above.
Any ideas?
I'm also REAL confused about WTH a "FLOW_MEATERS' is ....
sudo PRUNE_MODULES=1 rpi-update ef7621d91cb58ccc856c3c17ddda28685edd23f3
sudo wget https://archive.raspberrypi.org/debian/pool/main/f/firmware-nonfree/firmware-brcm80211_20161130-3+rpt3_all.deb
sudo dpkg -i firmware-brcm80211_20161130-3+rpt3_all.deb
sudo rm firmware-brcm80211_20161130-3+rpt3_all.deb
sudo apt-get update
sudo apt-get upgrade -y
sudo apt-get clean
sudo apt-get autoclean
Is there such a thing as a spell checker for scripts (or other source code)? Because I surely need one.From my dictionary:
FLOW_MEATER - noun, One who eats Flow M's or one who doesn't spell check Linux scripts. plural: FLOW_MEATERS
Thought it was timely to provide an update. Finally managed to get back to this and try again. After all else failed I unplugged the PIR and plugged in another (my order included 3 of them) and everything worked perfectly. I guess these things are mass produced and this one was causing repetitive triggers for some reason. All good now. One more quick question, I want to create a new image of my SD card and the last one took hours to complete (using a mac from terminal) I see a post about creating an image using the pi, can this be done using the card slot on the Alamode board?is it possible the PIR is firing so frequently it doesn't allow the screensaver to actually kick in?
There are two adjustments on the PIR. Try increasing the retrigger delay pot...
Cheers!
