HOWTO - Make a BrewPi Fermentation Controller For Cheap

So...I did the BrewPi install, but I forgot to write down the IP address where to find the interface. I'm sure if I looked through all 500 pages of this, I'd find it, but can anyone tell me how to find it without doing that?

 

It's been a long time, but I posted to this forum over a year ago how to figure out your wiring. I don't entirely recall the resistance values i got when I did it. but the gist goes like this. take your multimeter and set it to measure resistance. try different pairs with the multimeter until you read a resistance value (i think it was like .68 or .86 or something when I did it). once you have a reading look at what color you have attached to the ground lead on your mm. you just figured out which one is ground! now it's a 50/50 chance as to which wire is 5v and which one is data. so you can just use trial and error.

 

The IP address will be in your network, not in this forum……

Look in your router, under attached devices and find one labeled either raspberry or edimax

 

Leaving application ports open with active listeners can be risky.
When I was a captive employee I used to run a password-protected remote desktop program on my home workstation so I could get to it from work.

One late night I was doing home work and suddenly the mouse took off on its own - and obviously, under control of something sentient.
Eventually I was able to keyboard my way to the VNC icon and shut it down, but the whole episode scared the hell out of me.

I still have listeners on open ports (eg: my R'Pints/BrewPi hosts and all of their networked agents) but they're rather dumb machines with limited scope and no credentials to talk to anything else on my network - and still require a decent-strength password.

Everything else can only be reached via VPN - and a much stronger password...

Cheers!

 

Thanks so much. Mine was labelled debian, but whatever, I know what it is! Yay!

 

ifconfig in terminal will show you your IP

 

once I switched over to mega ohms I was able to get 0.9 between the ground and the other 2. But I had found another way to sort of check the probes. On the DS18B20 schematics there is a diode between the ground and data, and the ground and 5v. A normally functioning diode will read between 0.45v and 0.9v drop across the diode; mine gave me 0.55Vdrop. This test is nice since it is unidirectional. So between the 2 tests I know for sure that one of the probes is dead and that at least the ground was labeled properly.
I did a continuity test on the arduino board for the analog pins and although that seems to check out, I did notice at the time that the ATmega chip wasnt fully seated in the ic holder, I fulled seated it, reloaded my little onewire address checker and still nothing (and yes I tried multiple wiring configurations).
With some searching I did find a developer mention having seen the analog controller die on the physical ATmega chip without it causing other problems. So he suggested loading a little program for checking out the built in temp probe on the ATmega since its supposed to be on the same bus as the analog pins.
sadly this actually returns a value which would mean the analog bus should be fine.
at this point i wish i had an oscilloscope to test the 1wire communication just to see if its even trying.

well now I'm really confused but I think the easiest answer is going to be get a replacement arduino and grab some bare DS18B20 so I can wire them myself.

 

just tried this from the legacy dev branch - worked fine for me. Thanks again for your work elkoe

fwiw, if you are using an RPi as a BrewPi host you can find plenty of python scripts to read ds18b20 probes.

also fwiw, all of my probes are either red/yellow/black or red/white/black with a consistent 5v/one-wire/gnd scheme. So you're likely good if you followed that.

The probes that were messing with peoples heads used red/yellow/green and I'm still not certain if there was any consistent scheme...

Cheers!

 

And thanks for posting the session logs. From what I see there, I'm just about ready to try upgrading one of my backup BrewPi hosts and see how well the installer/upgrader copes with a non-standard, multiple-instance configuration...

Cheers!

 

You are using a 4.7k resistor right? I haven't actually seen you mention the resistor in all this

 

yeah the bag I picked up all measure around 4.6k ohm, with the worst being at 4.60 and the best being 4.66.
can 50 or so ohms throw off 1wire? Ive seen a bunch of documentation simply say ~5k ohm with then the schematic labeling the resistor as 4.7k so I figured this was within tolerance

Had to reassign pins. Same shield.
couldn’t set beer probe

 

I'm not using a RPi but moved over to my windows system and loaded a simple arduino program that looks for the serial id of 1wire devices (specifically DS18B20). In order to map your 1wire bus you need the 64bit serial id that was encoded on the device at its manufacture (this is really why 1wire works on one wire). The 1wire device should send out its presence pulse right after it receives the rest pulse from the master device (which is the arduino since DS18B20 can only be slaves on 1wire according to the spec).
here is why I'm pretty sure the issue is with the arduino; I can't get at the serial id of any device, wired in any way, on any of the A-pins. (hence why i needed a non arduino way to test the probes) If I wanted temp data I would still need to see the serial id of the device first in order for my program to ask for it, or at least be able to differentiate between devices.

Shoot thank you that helps a lot I guess I misread about having to solder connections after looking at pictures of the parts closely I can see that there's connectors on there for the jumper cables already. I will run to RadioShack for the jumper wires and it looks like that will make my life much much easier. Parts are in the mail and I'm excited to build this thanks for the quick reply.

 

Legacy dev seems to work fine. The beer sensor wasn't registering because I was trying to assign it to chamber rather than beer1. Doh. All good using legacy-dev with uno. Updated 2 UNOs 1 from 0.2.4 to 0.2.10 and 1 unused uno. Both ok

 

RadioShack jumper wires were made by the devil himself…

 

Im having trouble detecting my sensors. Ive been able to use the sensors and relays for another basic app which turns on and off the relay at certain temps. But when I try to install brewpi, brewpi cant detect the sensors even though nothing has changed in the wiring. All I can detect and install is the relays. Anyone with the same experience?

 

Can I run this program locally from a laptop without having to be connected to internet? I want to do a demonstration and show people at our brew club (doing fermentation controllers this month), but not sure I have wifi access where we have out meetings.

 

Get a switch or crossover cable bd use the Ethernet port to ssh in

 

I finally got my port forwarding working, but when I reinstalled BrewPi on my RPi, it installed to /var/www/html instead of /var/www/ as it was originally. I've got everything working except the password protection on the admin.php. I think I've put the .htaccess and .htpasswd files in the /var/www/ & /var/www/private and the /var/www/html & /var/www/html/private folders, respectively. Neither seems to be working as I'm not being asked for my login or password to access the admin.php. I think I have a lot of duplicate files since the instructions are for the old root directory but mine is a slightly different root.

 

If I hook the crossover cable to my ethernet port, where does the other end go?

 

Funny. I read that differently. I run BrewPi on an old laptop all the time, and other than needing internet for installing/updating or internal networking for seeing the graph without physically visiting the Chamber of Secrets, it runs fine. I will also quickly admit I've not religiously followed Ark's full thread to see if he's running BPi on RaspberryPi or laptop.

 

I was just wondering if the instructions on the Fuzzee brewpi build (the one stickied on here) are still accurate? I know that the brewpi crew is on a different model and that they have moved away from the arduino setup. I am looking to make the cheap version as in the post (no lcd or encoder) but am curious if I follow the instructions if I will end up with a properly working brewpi. Are the programs, codes and such in the same spots to run the installer etc? If not are there updates or somewhere to go to get it? As looking at the thread it seems that it is still going but before I dive in I was just curious.

 

I'd say they are up to date. Especially because they are still testing the Pi only model. I will be making a brew Pi in the next 2 weeks just waiting for parts to arrive.

In your other Ethernet port…

Your question was in regards to running ifconfig on the rpi, supposedly from your laptop. without Internet access this is your only option. if you were referencing bpi itself then yes you can run it on anything but you need network access to see it from another device.

 

Also ill state (this is what i do for a living) any relatively modern ethernet controller can do Auto MDIX and doesnt need crossover cables to go back to back anymore.

 

Hi Elkoe,

I just rebuilt my BrewPi from scratch to incorporate a RPi Zero and can confirm that the legacy_dev branch works fine - no issues whatsoever.

Cheers!

 

Thanks for confirming. I have already merged the dev branch into legacy, so you can use the legacy branch again.

 

I have a BrewPi running my fermentation chamber and love it. I now want to upgrade the controller on my keezer. For those of you who use a BrewPi to control a keezer or other serving vessel, how do you utilize the BrewPi? Do you just use one probe in the air in the keezer and use the fridge constant profile? Do you need a second probe to make BrewPi work correctly? If so, how do you implement the beer probe? Is it just taped to the side of one of your kegs? What say you all?

 

I don't see why you couldn't just run it directly on a laptop that's running Linux and not use the pi for your demonstration. I installed brewpi on my xubuntu box prior to completing the brewpi build and it ran just fine.

 

CadiBrewer,how are the pcb working? Any issues with the display scrambling?I'm waiting for my order from Dirt Cheap boards to get here.

 

I'd have to go back to look at my original post. I'm running BrewPi on a Laptop INSTEAD of a RaspberryPi...no RPI involved in this setup. Laptop ----> Arduino UNO ----> Sainsmart Relay. I thought the program might have been web based, so thought you MUST have access to web to use it. Now, I have found out through helpful peeps on here that it is just browser based, and I have to just point the browser to localhost. Done.

Thanks for all the help. I'm not a tech-guy, but I learn pretty quickly...just can't pick up on the lingo super fast.

 

Unfortunately,I had the screen scramble after running perfectly for two weeks. I need to check my enclosure because I threw it together quickly and there's some exposed connections in there, so potentially that's a cause. I'm also going to reflow solder in a couple of spots when this batch finishes fermenting and I can open the box up.

Worse case scenario, there's a hex out there from another member that refreshes the screen every minute. That seems to be an easy solution.

 

What relays are you using to control the cold and hot?

 

I'm using the Sainsmart relay card from the original post. The BrewPi runs flawlessly and the web interface is all you need, but darn it if it isn't cool to have the LCD screen on the box. My ten year old discovered the scramble. He told me that the screen changed to Chinese.

 

I want to use the LCD screen as well.I thought the screen scramble was caused by EMI from the Sainsmart relays and you can eliminate it by replacing them with a ssr

 

I found this from a Google search but I have know idea what it means
