I have been experimenting with RaspberryPints over the last few days. (RaspberryPi was a Christmas present.) For anyone who has been trying to get RaspberryPints to work over the last few years, you know how much a challenge it can be to get it to work, if at all. This is mainly due to the newer versions of the Raspian OS software, the Apache web server, MySQl, PHP, and a few other items that no longer function together from the RaspberryPints perspective. This all really 'broke' significantly as of Aug 2017 with deprecated libraries. (Don't be too concerned with these details if you have no clue what I am referring to.) And the original RaspberryPints site has (apparently) essentially abandoned the project years ago, leaving it up to hackers.

I have been successful in getting RaspberryPints to work using the latest RaspberryPi (RPi3 B) and Raspian OS (Oct 2017 release). Note that this is the non flow meter version - I'll tackle getting the flow meters to work at a later date hopefully.

If anyone is interested, I'll be glad to share an image of the SD Card as I have not tackled getting the original installer to work. (To be honest, I'm not even sure if I care about the installer now as I have RPints working just fine at the moment.)

My image is from a 16 GB SD Card. In theory, you should be able to download the image, (a 3.8 GB Zip file,) copy onto a 16 GB SD Card, plug the card into your RaspberryPi (RPi3 B), and be up and running. (I have already tested and done this on my own RaspberryPi.)

Before I publish access to the image file, I'd like to have 2 or 3 people first test to make sure that it really does work fine outside of my own sandbox. Please message me if you're seriously interested in giving this a whirl.

(A final note - unfortunately I am not in a position to be able to help much with SD Cards, unzipping, and the usual PC activities. I am making a presumption that you are a bit versed in PCs. That being said, you may still ask me of course, and if I know the answer, or where to direct you, I'll be glad to try to assist.)

Thanks,
Fred

Nice of you to offer to help out!

Yep. I understand exactly what you mean. These are the exact reasons I didn't go with a PC/embedded controller type solution for my brewing setup (different from your serving display/setup using RaspberryPints of course, but similar issues).

I've dealt with incompatibilities/deprecation for 20+ years and didn't want to have to rebuilt or hack my control panel to get it to work every few years.

(Kinda off topic, but my 2 cents). Wink

Cheers!

Kal

Yep, a very true statement. But what I do like about something that is software driven is that you can go in and make tweaks essentially for 'free' - headaches not withstanding! Every approach has it's place.

Super surprised the last commit was 4 years ago. Time to fork, and a great Q1 project.

Fred, I know this is an old thread but I just learned about Raspberry Pints and would love to use it. I have tried with very little success to get it work. I'm having a have a difficult time understanding the code changes, I do know how to turn a computer on, my code (screen) never looks like theirs.

If you are still messing around with it, I would appreciate any help, even test your Image file.

Thanks

Bob

Hey Bob,

There is an epic (92-page and counting) thread on Raspberry Pints over on Homebrew Talk.

It covers updated (and forked) versions, installation instructions, and troubleshooting. Good place to start.

Thanks for the info...I've read a lot of them and most are over my head. A good many of them talks about using it with flowmeters which I don't have.

Raspberry Pints seemed like a really cool project to me a couple years ago. But I'm not a coder and most of this stuff is over my head without any willing to learn.

On another note... since then, I've decided I want a netbook or cheap laptop or something in my brewery so I can have direct access to Beersmith while brewing. If I'm going to have that, then I think the plan will be to simply buy a Chromecast, figure out a website solution or something I can open in Chrome, and simply Chromecast my beer menu to the screen when needed. I haven't really looked into it but it just seems simpler for someone that doesn't want to tinker with it.

Don't @ me. Cross

Neat idea, and all technology aspects aside, I never really liked the logistics around having a screen to display a tap menu, at least not the way we use our bar at home. I didn't want to have to boot it up / turn it on every time someone wanted to go get a beer or see what's on tap, and didn't like the idea of leaving a screen on 24/7 like a bar can or would as they're a business (for energy use reasons not to mention the brightness with my adjacent home theater which you need to keep dark).

Flowmeters (to show how much beer is left) is an interesting idea in concept but they're somewhat flaky/inaccurate, plus the ones that are affordable probably do not have parts that are meant to withstand a good acid line wash or similar, so it's something else you have to take apart when it's tap/line cleaning time.

(My 2 cents)

Kal

I'll post an install cheat-sheet, it can be a PITA. The project has a lot of unofficial forks, as the mainline was abandoned some time ago. I'll do a write-up and post.

Kal - the swissflow meters are surprisingly accurate, but expensive. I scored a couple on eBay, but they're $60/pop USD. They clean well as part of regular line-cleaning. Some of the cheaper meters (like the adafruit) are less accurate, and I don't know how well they clean up. It's fun stuff to play with, and some of the smaller displays do well, but yeah, it's more for fun than anything practical.

Good to know about the swissflow meters. All this stuff is definitely interesting to play with!

the last updates were 4 years ago, just tried to install it on my webserver, it uses NGINX with php7.2 and it fails in the install, several people report the same issue

Now I don't feel so bad and that I'm the only one having problems. It looks like it's not worth the effort but as you say a cool idea.

so here's the issue, the script tries to get the root password to add permissions and users to the database of the server and that's not secure, nobody should give a web script complete control over its server and todays servers will not allow this especially Ubuntu, so itís a simple fix just rewrite a couple of lines in the install and do the server work yourself and it works, now Iím not going to provide that but if someone whatís to step up and fix it that would be helpful

There is also a way to use a motion sensor to at least put up a screen saver and wake it up when someone approaches. Still figuring out how to have it power off the screen and come back when triggered by the motion sensor.

Circa 1990 Beverage-Air BM23 retrofitted with SwissFlow SF800's.
Unit was not cooling below 45.F but after I swapped out the condenser fan, it can now chill below freezing.
PIR used to wake up monitor when approached.
Cheers!

I checked HBT and Raspberry Pints has been updated for the latest OS, php and DB. Currently being tested.
