NEW StrangeBrew Elsinore Thread

[user 101620]

OK manual mode was just outright broken if it wasn't set to 100%. I'd never noticed on my system because I always have it set to 100% at this time of year (I use an auxiliary 120V element since it's cold here).

Just pushed a lot of changes that fixes this.

 

[blitzer]

Everything is working! Thanks!

 

[user 101620]

Added scripts to allow Elsinore to be started as a service, see the main README.md for more information

how are you interfacing the mpx5010d for vol? Im using BBB and didn't know if i can use an open gpio or if i needed something to go between them.

You'll need to use a DS2450 (or voltage divider) since the MPX5010s are 5V and the BBB analogue is 1.7V

A friend of mine is designing some capes/overlay boards for RPi & BBB that'll break out known connections for one wire, GPIO, and analogue inputs so people can get setup faster/easier. I'll update when I have designs/boards.

Total cosmetic question/request:

I've got Elsinore setup (and working) with 2 PIDs and a third temp sensor. Currently is shows up in the UI as PID 1, PID 2, and Temp 1. How/can I rearrange these so it is PID 1, Temp 1, PID 2?

Planned, but it may be a while.

That's great. Any idea of the timing?

He's just working on layouts at the moment, everything will be run off one wire so I need to add some code to support OneWire GPIO

 

[user 101620]

Just uploaded a refactor of the webserver to use annotations.

I've tested stuff locally, but let me know if there's any issues.

 

[user 101620]

Still working on the pH meter stuff, I've just refactored a lot of the UI so that the volume editing is clearer, and it happens in a popover now instead of expanding out stuff. And it's better too since it gets the addresses of the One Wire DS2450s on your system (this is part of an upgrade I'm doing in preparation for the boards that my friend is getting made).

I've also changed the format of buttons that DON'T affect GPIOs or Timers.

pH meter code should be up tomorrow some time. I'll also be working on new documentation for the Volume Sensing when I get a chance now that the UI is updated.

Is this what I need to start playing with the ds2450? http://m.aliexpress.com/item/451172221.html?tracelog=storedetail2mobilesitedetail

World so I get that connected to the pi?


Thanks
Peter

 

[user 101620]

Finished the refactoring, it appeared to work previously but I don't think it was very reliable. Lots of changes are in for the pH Sensors. I just need to finish the rest of the UI code off.

Yes, that's what I use. I'll be writing up some documentation today.

Awesome... Thank you.. I will wait to buy it until you post the doc's to make sure I don't need anything else.

Got to order the ph kit too.

Thanks

Better priced ds2450

great write up.. think i will be changing over the BBB from my RPI. ordered the ds2450(15-21 business days this is going to be a long wait!). any recomendations on where to get the MPX5010D from? i am finding some differences from place to place on them. also the line that will go into your HLT/KEttel i am guessing is where the air escapes from and is why you need to keep the air pressure constant.



thanks again

Are you using MPX5010DP version?

Hello. Great thread, it has taken me quite a bit to read through it.

I'm in the planning stages of my electric brewery, Kal's website has been an inspiration, but I'm a computer geek that happens to love making beer, so I started looking at writing my own controller and I stumbled here...

I have 4 DS18b20 hooked up to my Raspberry Pi and I began evaluating the wonder package, Elsinore. Unfortunately, it seems with every update, I take a step back, which isn't a big deal as I'm just toying around. As it stands now, the UI comes up and I see all my probes, but I can't edit anything:

Are you using MPX5010DP version?

Yes, fixed the typo.

I got mine from OSCSYS before they closed down, but https://widgeneering.com/mpx5010dp_freescale_pressure_sensor_with_carrier.html

Is the same product. The carrier adds in some smoothing and improves the signal.

Looks like they are selling them again... says they have 7 in stock.. Humm might have to buy 2....

Thanks again

 

[user 101620]

Improved the graph axes layout as well.

 

[user 101620]

Weird I got a notification that geneda posted an issue with IllegalAccessException. I should have had this fixed yesterday, so if it's still happening please let me know.

Looks like my posts need to get mod approval because I'm new, I think.
My post finally did make it up, it's on page 47.

Anyway, I delete the SB_Elsinore_Server folder and did a fresh git clone. When I try and edit I get:

EDIT: I did a chmod 777 -R * on the directory, and the error went away. So, there's a permission issue somewhere...

 

[geneda]

OK, so back to some issue I was seeing prior to a few updates.

The LOCK button never appears for me, there is an issue with that toggle. I actually see it for a second when I click edit, but then it switches back to edit, but the controller is in lock mode.

Creating a PID, I have to enter the heat gpio twice. That is, I double click the header, add the heat GPIO, hit update, it doesn't change to a PID. Do the same thing again, hit update, it changes.

Also, I have never been able to get the timer to work. I create a timer, but when I click start, nothing happens (in either edit or lock mode) And the log is unaffected.

Also, where did the configuration file go? I wanted to see if I could change the logging level?

Strange no one else is reporting these issues, maybe it is because I have 4 temp probes (DS18b20) hooked up? Just trying to think what may be different in my test setup.

Can't wait to get this cooking, looks really nice.



EDIT: When I assigned a name to all my probes, I got a lock button!

I've pushed some more changes that should help. But the only way you'll get a permissions issue is if something is modifying your filesystem at runtime since you should be running as root. There will be error messages displayed very early in the log indicating this.

I've pushed some more changes that may help, but I'm not able to run Elsinore until Sunday at the earliest.

I removed the SB_Elsinore folder and did another git clone
This time no access errors, but all the items in post 476 are still valid

Have a good holiday!

The master branch has now been reverted to pre-refactoring changes until I can get it all tested when I get home.

For now, the pH Sensor code and refactoring are in a separate branch

I'm getting the following when trying to run 'sudo update-rc.d elsinore defaults' after updating the 'elsinore' file to get Elsinore to run as a service. I removed the comments on the lines as stated on the github README. Not sure what the issue is.

If I try to run './launch.sh' now, all it says is 'Starting Elsinore as root'. It stops there, and I see nothing else.

Any ideas?
