NEW StrangeBrew Elsinore Thread

[user 101620]

Hello.

It is possible these two implementations?

1 - trigger for a alarm with this Active Buzzer Module:
http://www.ebay.com/sch/i.html?_odk...&_nkw=active+buzzer+module+raspberry&_sacat=0

Just add it as a switched output, and you can set it with a trigger.

2 - implement a button to shut down Elsinore and Power off raspberry Pi.

Greetings.

I can add a shutdown Elsinore button, but I don't like the idea of shutting down the RPi at the same time, I'll think about it and maybe have it as an optional extra

Just add it as a switched output, and you can set it with a trigger.

For buzz sound I need a script same this:

import time
from RPi import GPIO

PIN = 23

BUZZER_REPETITIONS = 300
BUZZER_DELAY = 0.0005

PAUSE_TIME = 1.0

GPIO.setmode(GPIO.BCM)
GPIO.setup(PIN, GPIO.OUT)

while True:
    for _ in xrange(BUZZER_REPETITIONS):
        for value in [True, False]:
            GPIO.output(PIN, value)
            time.sleep(BUZZER_DELAY)
    time.sleep(PAUSE_TIME)

Probably this need a global timer (input alarm time).
Trigger is good for end steps alarm, and end mash alarm.

I can add a shutdown Elsinore button, but I don't like the idea of shutting down the RPi at the same time, I'll think about it and maybe have it as an optional extra

Poweroff button it's good because it saves having to go to the command line to shut down.
Power on rpi and start elsinore automatic, later brew time, and finally push button and poweroff system.

How bad is just pulling power? I've had no issues. As long as you use ext4 (journaling) fs, my understanding is you don't have too much to worry about. I run my controller headless on a pi and just yank power at the end of brew day. I haven't had any really big issues.

(OG rpi, overvolted, overclocked, ext4 thumb drive rasbian install, Wi-Fi dongle, no usb hub, custom power supply to maintain 5.2v across tp1/2)

There are now two buttons when in edit mode. "Shutdown" and "Shutdown System".

"Shutdown" will just stop Elsinore, "Shutdown System" will shutdown the full system.

I've also modified the alert boxes to use sweet-alert which is much nicer.

Hi, everyone. Just started building my brew controller with RPI B+, and was wondering if anyone has used a BrewPi Rev C board for connecting temp probs and SSR's? I cant get the schematics on the original website anymore. I would like to use it instead of a bread board as it already has 4k resistor and connectors for the temp probes plus some LEDs and connectors for the SSRs.

The reason for wanting to use it is because i have one sitting in my cupboard gathering dust. Just thought of putting it to good use if possible. Unless anyone can recommend another cheap and easy alternative.
Thanks

this is what I was talking about... another case for the new, hardware-centric Elsinore thread (still to be created). Doug, do we have your go-ahead? Or am I solving problems that don't exist?

I have no idea what the BrewPi uses for temperature probes, or what it has as outputs. Sorry, I can't advise you on this safetely.

No, you're right, there should be another place to do some of the more specific questions. There is www.reddit.com/r/StrangeBrew/ which may be easier.

 

[Dash777]

Sorry if I'm crashing this thread, didn't know where else to post. Noticed "FuzzeWuzze" mentions using brewpi, just wondered if others where too, and if anyone had a schematic drawing of the board.

 

[512brew-com]

okay, well I don't understand reddit as a service so I can't help there. Call me an idiot, I just don't understand what reddit is all about. My thought was to start a new thread here on HBT to address questions related to hardware Elsinore implementations. It's annoying for those of us focused on software questions to be interrupted by h/w system stuff... we might like to delve into both (myself included), but it would be best to have those subjects separated. As an example, we might be cruising along on possible software feature upgrades when suddenly someone comes along with "how do I install this on rev X of my RPI X board and how do my analog sensors work with Elsinore?" questions... that should be a separate thread, yes?

We should be focused on software functions and debugging on this thread, if I understand properly, not on all the multitudes of physical implementations. Yes? Tell me to clam and I will.

Trying to help, will shut up on command....

No need to shut up, I just don't understand why you're asking me for permission, I don't rule what threads you make (I don't think i do at least?) The point is that this is an organic product and you as users can do what you want, one guy is even making money from it.

Speaking of money, I still think you should put up a donation link in your signature.

Sorry if I missed this earlier in the thread... What is the best setting for the boil kettle? Auto or manual. If set to auto I assume I would set it to 212 but I'm confused on what the Duty time and PID settings should be. And since we are on the subject what about the HLT or atleast a good starting point. Thanks of the awesome software!

 

[JayElDubya]

I'm on my phone so grabbing the link is tricky at the moment, but there are some good PID tuning write-ups. Alternatively, just experiment. If you're in the US, set your duty time to 1.7 sec. That won't change. Then start with a P of 40 and leave I & D at 0. Set the temp to 213 or 214 and see if it lands you at a rolling boil.

edit: Adding link. Thanks Justin. Love the site!

http://onbrewing.com/strangebrew-elsinore-faqbrewery-calibration-pid-setting-specification/

edit2: The 1.7s is complicated to explain and/or understand if you're not REALLY into math, but it's THE lowest you want to go (with 60-Hz US AC power) without getting aliasing according to the Nyquist–Shannon sampling theorem. If you live in a country where the AC voltage is at 50 Hz, the lowest you want to go is 2 sec. Anything higher than those values is high. The lower the number is, the more fidelity and control in switching SB Elisinore has, with higher numbers, you decrease the amount of time your SSR is switching. I've been running mine for years with no issue at 1.7. HMMV.

Thanks of the awesome software!

Here is what I do on my current Auber PID based setup, it seems to work very well for me. I brew BIAB so after my mash at 152 or whatever temp, I ramp u to mash-out 168 using the "Auto" setting in Elsinore would be the equivalent. After mash-out I ramp up to 204 using "Auto", this way I almost hit a boil but I can walk around and do other things like measure out my hops, grab a beer, etc... ...and I don't have to babysit the kettle. Once I notice my kettle is at my set temp I then switch over to "Manual" and set it for 100%. Think of the percentage like a dial on a gas regulator. You use this to control the intensity of your boil. You can dial this back to get the intensity back to what you want, I typically dial back to 85% and get a hard rolling boil with a 5500W element having 15gal of wort in my kettle.

I hope that helps a little.

 

[JayElDubya]

Why not just use auto to maintain the boil? We haven't had a boilover since switching to SBE and using auto.

I like to control the intensity of my boil, if auto works well for you then I certainly wouldn't change. I just figured I'd outline my process in the hopes that it might help.

After I'm done mashing, I set the boil kettle to manual, 100% and a 2 second cycle. Once it's boiling, I dial it back to 65%.

yeah, but I figure it's just polite to ask the OP what they think before I go making related threads.

Dear Doug / all

is anyone else having problems when trying to set up a pid for cooling?

when all my pids are set for heating all works perfectly. currently i have hlt mlt and fridge as the names of my three pids and one pump switch. ive been doing a few test runs on my brewing rig this week and it is superb in brewing / heating setup. i decided last night to start running a test run on my combined fermentation chamber / kegerator. so i set one of my pids (Fridge) to cooling which i planned to use in hysteria mode

first problem - i set the gpio settings (inverted) to GPIO22 and hit update all seems ok but when i switch hysteria mode on nothing happens. see getstaus below

second problem - i thought i would try restarting elsinore after i have changed my gpio from heating to cooling to reload the config file. when i do this the pid buttons have disappeared on restarting even though the gpio settings are still there when i look in edit screen ? i then hit update again the pid buttons reappear but the hyteria mode still doesnt work?

if i change back all pids to heating and restart everything works great and my relays happilly click away!

i hope the description of my problem is ok

cheers

mike


here is get staus with all 3 pids running in hysteria mode - heating

im thinking looking at the get status output that when i try and set a cooling pid the web browser is not updating elsinore config file porperly ? or not communicating properly with elsinore as the duty is still showing 0 when it should be 100 ? but also the output on the web ui also shows 0 so maybe the command is not getting passed to elsinore when the cooling pid id set ? ive tried firefox chrome and ie with no luck. but to be honest ive learnt loads in the last few months playing with the pi but im still clueless !!

I haven't tried setting up cooling for a fridge yet but when I do I'll test it out and let you know.

Quick question about ADC for volume measurement.

I've read the following guide:
http://dougedey.github.io/2014/12/20/Volume_Setup/

Is the setup limited to the DS2450 ADC? A more readily available ADC in my neck of the woods is the MCP3008:
https://learn.adafruit.com/reading-a-analog-in-and-controlling-audio-volume-with-the-raspberry-pi

Accepts both supply and analog voltage of up to 5.5V. Major difference as I see it is that the MCP3008 is 10bit as opposed to 8bit, which could affect how SB reads the values?

What are you trying to set the cooling GPIO to? Are there any error messages on the elsinore logs on the server?

The issue is when someone pays money they start demanding service and support even though no support contract has been decided. I have updated my signature with my paypal address so people can send me donations, but to have a donation link requires a business account which I do not want to pay for or manage.

I can relate to that. I think that some of us would just like to send a little thanks to you for creating something that is fun for us to tinker with.

Hi doug

i am using gpio22 for a pid which is currently called fridge

in hysteria heating mode with output inverted it works with no problems

when i try and change from heating mode to cooling i get the following on the server screen and cooling doesnt work

Is your cooling GPIO GPIO22?

 

[user 101620]

Is there any other output? What's the next warning?
