StrangeBrew Elsinore An Opensource Brewery Controller
Strangebrew Elsinore Server
Java Server for Strangebrew Elsinore
The purpose of this project is to create a Java application that can run on small systems such as the RaspberryPi and the Beaglebone series
Since these systems run on Linux, that is a requirement to using this.
The system is based off the Dallas One Wire protocol for the temperature probes (expanding to analogue inputs too), and Straightforward GPIO outputs for SSR control
Setup Instructions
The above instructions will tell you how to setup your systems for Elsinore
Startup Instructions
Clone this repository:
git clone https://github.com/DougEdey/SB_Elsinore_Server
Move to the checked out Directory:
cd SB_Elsinore_Server
Run:
./launch.sh
Wait, what happened to the old instructions? Well I found that people weren’t following them well. So I rewrote the UI, you can now setup everything (almost) from the UI.
If you have a DS2450 (or don’t want to use Analogue inputs for reading the volume, BBB is 1.7V so not very good for reading the analogue inputs. You will see a request for OWFS, please use OWFS if you can, it’s better in general.
./launch.sh

Do you want to switch to OWFS? [y/N]

Creating the OWFS configuration.
What is the OWFS server host? (Defaults to localhost)
What is the OWFS server port? (Defaults to 4304)
Then you can use the web UI.
Web UI
The standard view you’ll see at the start is an un-named display, such as:
The probe “names” are their addresses, double clicking them allows you to set them up
- You can set just the name (which will leave it as a temperature probe)
- A GPIO pin (which will set it up as a PID controller)
- And if you use a GPIO Pin you can set an Aux pin at the same time, allowing you to use an auxilliary ouput.
Volume Reading
Volume reading can be done using any analogue input, I personally used the same hardware as Brewtroller connected to a one wire DS2450, this allows it to connect to the one wire bus.
RaspberryPi or Beagleboard?
The BeagleBoard Black does have a big advantage over the RPi, it has onboard analogue inputs, but these are 1.8V.
The RaspberryPi works fine with the existing software, the only thing you need to do differently is naming the GPIO Pinouts.
One Wire & OWFS
One Wire is fantastic (in my opinion) each sensor or device has a full 64 bit address, and you don’t have to worry about the order and you can chain them!
One Wire devices can be chained, with only one Pullup resistor before the first connection to a device. I currently have 4 Temperature probes on my circuit, and a ADC, connected using XLR jacks.
OWFS is a much better One Wire Implementation, it is highly recommended to install it, and it is REQUIRED if you use One Wire based Analog inputs (like the DS2450
Install it using your standard package manager, then you need to set a mountpoint up (I use /mnt/1wire) and set
server: w1 in the OWFS configuration File (/etc/owfs.conf by default), you can chose the ports as you want for OWFSHTTP and OWServer, the configuration tool will setup OWFS if it can.
To manually setup OWFS, use the option -owfs when starting up Elsinore
Cutoff Temperature
After the incident I decided to add a cutoff temperature, in my case I have a temperature probe on my SSRs, and when they go over a certain temperature I want to kill the server so it doesn’t get badly damaged
This is to come in the updated Web UI setup.
System Temperature
System can be enabled during setup by entering “system” (no quotes) at the prompt.
Also, to enable the System Temperature reading, please add
<system />
In the <general> section of the configuration file.
Timers
Use the web UI, click on “Add Timer” to create a timer.
Pump Control
To add a pump, use the “Add Pump” button on the Web Interface
Config File
This is now automatically controlled, you shouldn’t need to do anything to it, except for backing it up.
