BrewPi Remix – What’s Old is New Again

[LBussy]

I do use RJ11 and RJ45. I still use a lot of ferrules any time I need to make a mechanical connection with stranded wires. For instance, using them makes connecting the AC voltage to the relays in those little crimp blocks very secure.

I have a 3D printer that uses a ton of wattage and bad connections often lead to melted connections or worse. If it works well there, it will work well here.

The tiny XLR are great because the provide a soldered connection + a strain relief to keep those wires from bending. Expensive compared to other solutions, but worth it when your project goes to it's "final home."

Are there any brewpi / kegland rapt pill projects in the works?

I doubt it. It was addressed here a couple of times. Just do a search in this thread, to find out the reasons.

 

[bloombrews]

Yep.


Well, two issues with that.

1. The three hair-thin strands of copper in those leads still are not very large in diameter; the ferrule "bulks" that up a bit making a more reliable connection with the various physical connectors.
2. The above-mentioned three strands of copper will break at the solder point. I know this is a religious debate among people but all I know is I have seen it happen to me and I prefer a mechanical connection for these.

Do you cut off the factory (very short) soldered tip, then strip off a longer section of naked wires, and insert the naked wires into the ferrules, or solder the newly skinned wires, and then insert into a ferrule for crimping?
I would think that these super fine gauge wires, would still not make a very positive connection inside the crimped ferrules without first re-soldering on a new longer tip. I never used these before, so just asking so I do not have to redo them again during a fermentation run....
It looks like @day_trippr has a better source to buy his temp probes, as mine have fewer strands than his, pictured above, and mine are so fine, you do need the Hubble Space Telescope to take a picture

I fold over the factory tinned ends and slip the ferule over that and crimp. “So far so good.”

How do you delete Chamber(s) "Arduino" UNO Controller, from a Mult-Chamber set up?
Also, I could not find in the Documents, How to rename ("friendly" name), of the Chamber UNO Controller?
I am trying to find out why I have occasional RPi losing the running Script, and was trying different Controllers, to see if I could find the problem.
I do not see anyway in the GUI to do this, and not sure what command to issue in the Terminal

 

[bloombrews]

Craft Beer and Brewing magazine just sent me an email about a new Accubrew Fermentation Monitoring System...
Looks like an expensive Tilt/iSpindle setup... LOL @Thorrak
Does look sweeet though!
Curious how they get the signal from this long Tri Clamp well ?

EDIT - The $295 looks super good/sensor, but what is the expensive long term "Subscription" to monitor the cheep sensors??

Run the uninstaller , it will give you the option to remove one chamber.

Also, I could not find in the Documents, How to rename ("friendly" name), of the Chamber UNO Controller?

I think the only way will be to edit the config.cfg file.

 

[bloombrews]

I think the only way will be to edit the config.cfg file.

Where can I find this folder/file, or line in the script? I have two controllers with the same name, which is not helpful to see if any of them may be bad, causing problems with lost script communication with the Pi.

 

[LBussy]

Should be in: /home/brewpi/{chambername}/settings/config.cfg

The line should be: "chambername = Foo"

After you are done, you will want to issue the command "sudo systemctl restart {chambername}"

Ahh, yes. Modern software. Subscriptions as a Service.

No idea how an optical gravity sensor works though. Would be interesting! The only thing that seems missing from Fermentrack/TiltBridge is alerting. I think I know how to fix that…

I run BPR v0.8.0 and Gravitymon v1.3.0beta3 (iSpindel).
In config.cfg, I have defined this line:
iSpindel = gmon-blu
which corresponds to the name of the Gravitymon unit.
Everything is fine, but in the Date/Time table on the right side, I never get historic values of "iSpindel SG" when I drag the cursor across the timeline.
I've tried other settings in config.cfg too, but end up with script not starting.
The only "wrong" thing I have spotted so far, is that the SG line in the chart is green and iSpindel SG dot in the Date/Time table is red. Colours of all the other values corresponds.
Any clues? Anything missing in config.cfg?

HAPPY BIRTHDAY BREWPI !!
March 19, 2014
FuzzeWuzze posted the first time here on HomeBrewTalk, his rebuild of Elco's BrewPi
@day_trippr , @Thorrak , @LBussy , and Others, have taken this on, made it much better, and started other really awesome brew projects.
The rest of "us", are just here (at least I am), to try and take what they worked sooooo hard for , and attempt to duplicate it ourselves in our brewery.
Anyway - Happy Birthday BrewPi !
Hope FuzzeWuzze is still out there and in good health....
Ed Bloom, North of Pittsburgh, PA out in the Country, brewing away!!

Time flies when everyone is having fun

 

[Thorrak]

None of this would exist without Elco, and his decision to make BrewPi open source. It’s been a fun project to tinker at the edges of, and has absolutely resulted in better beer (at least for me!)

This DEFINATELY, has resulted in better beer, and lots of medals, for me also!
I remember haveing to stick thermometers in the beer, and using an expensive $300 infrared scanner (when they first came out in the 1990's), to try and track (on paper), my fermentation temps...... Stone Ages!
Thanks YOU ALL, so much, for sharing this with us! For me, it was not trying to save $300, it was to try and make the best beer possible. The $35 Raspberry Pi, was a wallet killer ! LMAO !

Hey man - that $35 raspberry pi has been selling for a lot more on eBay as of late! It’s been cheaper to pick up SFF Intel-based PCs, which feels crazy when you think about it!

I just ordered one from Amazon a few days ago for $49.99 !!!

MazerPi Raspberry Pi 4 4GB Max Kit - 64GB Edition, Raspberry Pi 4 Case with Fan, 20W 5V 4A Raspberry Pi 4 Power Supply with ON/Off Switch, HDMI Cable for Pi 4B (4GB RAM)​

And the price went up to $229 sometime between March 14, 2023 and just now!!! WTF!!!
I do not know if that was a mistake, or they are trying to HOSE us all now, since they realize they can charge whatever they want . I think the reason for the huge shortage, is that they are being diverted to Ukraine for Drones and other equipment.The Raspberry Pi Foudation, say it is NOT there fault, but they are trying, and unable , to keep up with the demand. They (Raspberry.ORG) are selling the R-4 for $35, but almost everyone is marking them up to what ever the market will pay now.
I should have bought 100 of them, and retired on the windfall profits..... Not sure if I am getting a clone junk, or the real deal ?
EDIT --
I rechecked Amazon again, and Amazon is F'ing us now. I can have it tomorrow for $229 (in stock), but when I ordered it last week, it was April 5 to April 26 delivery (from China of course...). So, there you have "It"

While it’s possible, I’d point to the fact that - as I mentioned - SFF PCs are readily available for $100-120 which - if I was trying to build a drone - feel like a much more powerful option! My guess is that the raspberry pi foundation isn’t wanting to scale beyond what they think is sustainable — while underestimating the growth in interest in ARM-based PCs on the heels of Apple’s success. Still though, who knows?

 

[day_trippr]

I doubt anyone is buying RPi's for desktops as they still just don't have the balls to do that job well. I suspect people building clusters for all kinds of reasons are devouring mass quantities of Pi's while The Foundation is still constrained by supply chain issues. They may not be able to source components to support expanding their production even as the utility of RPi clusters has become accepted as viable...

Cheers!

 

[bloombrews]

I'll find out soon, if the V-B4, has any bigger One's, then the V-3B+. When I try to run BPRemix and surf the Net, the V3 starts to smoke, and the green light is pretty much constant on, waiting for the CPU to finish up. You Brainiac's would know a lot more than me, if the 64bit, with 4 GB RAM, will be much better ?
I still have an occasional freeze-up, that three different Raspberry Pi's green light is constant on, and I can not open the Terminal Window to kill the Process.... Led to too many busted SD cards when I had no choice but to pull the cord...... UGH! I still have no clue what can cause my Pi to freeze up. It happens much more when running BPRemix, and much less often when running Fermentrack ? I must say that when I tried the Raspberry Pi Desktop LEGACY download, the freeze-ups almost dissappered completly. The newest desktop will cause this issue 3-4 times/day, where the Legacy may chug along for a few days, before ice sets in....

CLUSTERS!! Well I do have two Version 2 Pi's, and three V-3B+, and a V-4B on the way..... so this may be a solution to my pollution on the desk?
I never had any problems for years, running BPR, then I started to brew beer again, after 1.5 year lay-off (due to no time available, riding a bicycle many miles, and home construction projects....), so I loaded up the newest RPi desktop, and new copies of BPR, and then the problems began....
This "Cluster" is really a nice concept, that I never thought of - just knew there had to be a better use of 5 Pi's sitting around collecting dust or crunching BPR now.
thanks @day_trippr - more "toys" for the Old Man to play with!

 

[LBussy]

A cluster is not useable as a "box of Pi's." It takes specific softeware and knownedge along with cluster-capable applications.

Thanks Lee! I will tell the Ol Ladies at the next pie, church bake sale.....
I knew "it" could be above my scale... but all my Pi's lying around?

 

[kmllr315]

Hello all, I have an old BrewPi that I’m working on updating to BrewPi Remix. Everything seems to go fine until it runs for a couple hours then the graph stops updating and the script cannot connect. Wondering if it has something to do with the Tilt? I sometimes use it but only for lagers and not all brews. I think I saw on the internet somewhere that the Remix might timeout on trying to connect? Would that also stop the script? Any other ideas to try? Thanks in advance!

 

[LBussy]

Welcome, @kmllr315!

The answer is "it depends." You should have a look at the log and the error log and see what might pop up that's not expected:

• Standard log is typically at: /home/brewpi/logs/stdout.txt
• Error log is typically at: /home/brewpi/logs/stderr.txt

 

[larsh]

I have connected an iSpindel to BPR 0.8.
I do get correct values in the top blue banner.
Does anyone have any idea why I never get any iSpindel SG numbers in the table on the right side?
