NEW StrangeBrew Elsinore Thread

Will this work to be able to run Multiple SSR's from one pin?

The schematic and the parts list down not match up. Parts list says you get a 2 pin terminal block and a 3 pin terminal block, 5 terminal points. The schematic shows 15 terminal points.

If we assume it will works. You can pass multiple SSR control signals through the Mosfet.

Going by the parts list, I assume you are making a switch that pulls to ground. Put a positive source on the plus terminal of your SSR. Use this to switch the negative side of the SSR control. Your On/Off goes into the Mostfet gate. (marked control where the resistor connects)

 

[Cletus81]

In reading through the thread it looks like the Pi can not handle more than one SSR connected directly to one of the GPIO pins. I am trying to connect multiple SSR's and thought this would be a bit cleaner instead of wiring things directly to a Mosfet. Does this make since?

In reading through the thread it looks like the Pi can not handle more than one SSR connected directly to one of the GPIO pins.

You need to look at what your particular SSR. Determine what the trigger requirements are. Voltage level, current draw, etc. Then look at what a Rpi GPIO can handle.

I believe the Rpi has a maximum you can draw, in total, through all the GPIO pins.

When you use this 10K resistor & mosfet, the Rpi GPIO pin sees a 10K resistor. With a 3.3v Rpi GPIO, that counts as .33 ma.

The screw terminal blocks make termination easier. You have to figure out how you are going to secure the PCB in place.

So I'm finally brewing again. I'll fix any issues as I find them

 

[SilverZero]

On the drawing I was looking at under the Raspberry Pi setup, it says to connect the DS18B20 data line to the RPi pin 4. On my RPi 2 model B, pin 4 is another 5v pin. Should I be using GPIO04 (GPIO-GCLK) on pin 7?

 

[wbarber69]

They mean the 4th pin from the right on the top row. GPIO04

 

[user 101620]

Yes, I can't believe that I missed that and no-one pointed it out.

 

[SilverZero]

Great, thanks! Just to clarify for myself and others (because my "right" and "top" may be different than yours): GPIO04 as in pin 7, as shown on this pinout. Maybe people who know what they're doing count pins from the right and orient the board differently than me, but I'm going off of that pinout image. Correct me if I'm wrong!

I have a question I finally got my pi all wired up and installed the software all probes are working fine pumps working and ssr. My question is I see that there is a new option to control the size of the temp gauges however when I set the to the size I want after rebooting the system the size that I pick has to be reset is there anyway to set this size as a default? I am also having issue getting the script to auto run at boot up. I cp the Elsinore.debian to the /etc/init.d folder and did the update as per the instructions when I do a sudo services Elsinore start is says it's running with PID ???? But when I try to access the server is is not up. Any help that anyone can provide would be great thank you.

Did you chmod +X the script?

 

[TechyDork]

I know you can set SBE to run as a service at startup, but wasn't sure if this was limited to a specific OS. I am running Rasbian on my Pi B+.

Can i set it up as a service? My brew partner isn't computer savvy so ideally i would like him to be able to just turn on the control panel and then open the web interface on his tablet to start heating up water in the HLT.

I already have a static IP set on the Pi.

 

[TechyDork]

did this thread get lost in the move to the cloud?

 

[wbarber69]

No it's just one of those threads that seems to be a barren wasteland at times once the posts start back up though they'll flow for a few days and then die back down.

I think the Debian init.d script should work for you

Is there a tutorial on how to set it up?

 

[TechyDork]

found this tutorial. I am not a big linux guy, but i am slowly learning. I plan to give it a shot this week and see if I can set this up.

I have a Hosehead with the B+ in it, and I have Elsinore running as a service. The instructions to do so are in the readme on Doug's github site. You probably already have the files from your install, but they are available on github too if you don't.

I must have skipped over that. I will give it a look again.

thanks,

 

[TechyDork]

I assume since i am using the Raspbian OS i would use the elsinore.debian file in place of the .ubuntu file?

Correct?

 

[wbarber69]

2 weeks I waited for a 7" touchscreen to come from China. And the damn thing doesn't even turn on. It'll be a solid month before I can continue on with my project!

That's a huge bummer!!

Any reason you can't run it via a laptop or tablet?

 

[wbarber69]

Because my laptop won't fit in the enclosure I have everything going into.

 

[FuzzeWuzze]

Because my laptop won't fit in the enclosure I have everything going into.

Are you not going to have it on your network? Or just want a touch display locally for ****s and gigs?

 

[TechyDork]

Right, but the SBE is designed to work over your network so that you do not need a screen or anything connected to the enclosure.

The touch screen is a good idea, but i am not sure how practical one that small will be for running SBE.

Your best bet would be to get the Pi up and running on your home wifi. You will need an el cheap USB WiFi adapter to do this and then just set a static IP address for the Pi. I just take the Pi and connect it to my TV via HDMI and then fire it up and connect it to my WiFi and then tell it to use a static IP address.

Once you have SBE installed on your Pi you can follow the steps to set it to run as a service at start up. I am currently working on this part.

Once you have that all set then all you have to do is power up your control panel and the Pi will connect to your WiFi and SBE will start up.

then use your laptop or tablet connected to the same wifi network and open the controller via your favorite web browser.

Or if you do not want to use wifi you could make a crossover network cable to connect directly to the Pi from your laptop. You will need to know how to set this up with the proper IP information.

 

[wbarber69]

Like I need an explanation of how it works. My brewery is mobile. My control panel is mobile. So everything will be handled locally. But thanks for all the help.

 

[decoleur]

@wbarber69 maybe we can all use a little help sometime.

Have you noticed the performance difference between running xwindows and a web browser on the same platform that is running SBE?

I have.

In my experience it is always better to run a web application on a box that isn't running the web browser that is using it when resource contention can be an issue.

Have fun with your build!

My apologies. I only meant to provide assistance and not to offend. I am in IT and I enjoy helping others with their tech related issues.

I second the comment that running the browser on a separate machine from the Pi will only improve performance.

Please post your experience when you get the touch screen up and running.

Happy Brewing.

I believe that is what others do

You could theoretically set up an ad hoc network between the pi and an external laptop (either wired or wireless)... rather than being tied to your brewery having network connectivity... which is understandably a concern of yours if you are mobile.

I don't know of anybody using a touchscreen yet with one of these set ups. I think Doug may have an LCD panel built into his brewery controller. Definitely let us know how it goes...

In the future I may put ubuntu or debian server on my beaglebone to reduce resource use since I don't use the GUI locally.
