[Version 2 Release] RaspberryPints - Digital Taplist Solution

[DirtyRed07]

One more question. So I’m trying to get my background image to fit the tap list screen. I’ve tried changing the file size of the image and then uploading, but no matter what I change the size of the image to, it still enlarged it on the actual tap list and cuts the image off. Is there a way to do this? Thanks

 

[RandR+]

Is there a way to do this?

You may need to play around with the styles.css file
These lines deal with the background.

without seeing the issue I cant tell you what the styles need to be, you can post your background image here and I can see how it behaves on my setup.

I’ll have to get the actual image off my computer later, but as you can see in this picture, the image is too big for the screen. About 1/3 of the image is cut off. (Unless I had more than 3 taps, then it would scroll to the bottom of the image I’m assuming) hope that clarifies a bit.

 

[RandR+]

About 1/3 of the image is cut off.

try switching cover to contain in styles.css
Like this.

Most likely it will leave some space to the sides of the picture but you will be able to see the whole thing

Have a new issue...but... I did work out all my own stupid wiring gremlins to get all 4 of my taps to send flow data and value opening...problem is...it only works for the taps page....If I use RFID....it opens and closes the valves almost right away...maybe .25 to .5 seconds on.....here is the log info....any help would be great. Thanks.

This is a failure using the RFID...

The problem is that the Arduino restarts right after the RFID is scanned. This closes all the valves.

I suspect a power dump opening the valves is draining the power to the Arduino which is causing it to restart. I would power the valves separately then the Arduino to help prevent this.

You can see if that is the case by unplugging the valves power, scanning RFID and then looking in the log to see if there is an Alive message after the RFID scan.

I had a similar but different issue. My valves would open, as I started pouring the beer non pouring taps would close, but when I was done pouring and the last valve closed the Arduino would restart. I unplugged the valves to test and it didn't happen. Now they are plugged in and its not happening. I suspect I had/have a loose wire

I tried changing in file manager and saving, that didn’t work. I know you had said to get into styles.css via the terminal and sent me the command, but I’m not sure what my installation path was and var/www/html didn’t work. How can I find my installation path?

I thought the exact same

Definitely good - and in this case, necessary advice. Anything with a coil can throw an inductive sag. We usually get away with the tiny relays hanging off Arduino boards, but a solenoid is a much bigger beast...

Cheers!

 

[RandR+]

How can I find my installation path?

The installation path is just the path to where the files are located. if you can get to the style.css from the explorer or a text editor the directory path of that file is the installation path.

The address bar of the explorer will give you the path if you can see the file

you said you found the file in the file manager, if so then the path where that file is the installation path.

One thing to remember with Linux based operating systems is that you need / infront of the path when changing to a new directory
so in the terminal you need to type (for example)
cd /var/www/html

So I wasn’t fully understanding how to open the text editor...but I did finally get what you were saying, apologies. However, when I got in there, it appears that changing it to contain in the file manager also changed it in text editor. Problem is, it didn’t change the image at all.

it sounds like you changes are saved, did you refresh the webpage after the changes were made?

Without the file itself it will be hard to tell you what to change. there are developer tools built into the browser but that may be a little advanced for you

Yes. Refreshed page, logged out and back in a few times, rebooted pi a few times. Image is the same still. I’m 100% sure developer tools would be too advanced for me haha. Guess I’ll chalk it up to a loss. I appreciate all the help along the way though.

one thing you could try is to shrink the image then add blank space under it to trick the browser to display the image itself and cut off the unwanted blank space

I’ll give it a shot. Another thing I just noticed is that I don’t have the 3 tabs that I used to have (one was reboot) on the Home Screen of my page anymore. It’s just welcome message.

Those only display if you have flowmeters configured because they use python to perform the tasks

So I just changed the image to a different one to see if it would cut it off too, logged out, rebooted pi, logged back in and it didn’t change the image, it’s still on the old image. When I logged back in it shows the background image saved to the new one.

 

[RandR+]

well thats odd, if you navigate to your install path then open the img folder the background.jpg should be the image RPints is using.

Im thinking the browsers cache is causing the old one to be used. I believe that control + F5 or shift + F5 will cause the browser to ignore cache and reload the page

The background.jpg image in the install path is the default black image. Crtl +f5 did what you said and changed it to the new image, although it still loaded with the old image.

 

[RandR+]

thats odd it should load the image file img/background.jpg can you try from a different computer/phone that hasnt connected to your RPints yet?

Loads old image when I go on my phone. I have 4 html folders, not sure why, but none of them show the old image when I click background.jpg, 1 of those 4 folders is empty.

Edit: I just rebooted and it has the new image on screen, but if I use cover, the image is too big like the old one. If I change to contain, it takes up about half the screen so it’s too small. I’m assuming this is an issue with the actual images themselves. Though I’ve tried changing their file size to no avail.

 

[RandR+]

A new HTML folder is made when you reinstall or update as a precaution.

Though I’ve tried changing their file size to no avail.

it may not have to do with the size of the file, its more likely the size of the web page components displaying them. there may not be a way to get a perfect fit without a lot of changes to the style.css

Finally was able to get this (almost) right! Had to download an image converter and convert the image to PNG, then resize it with a different app made for that. Just have some minor tweaks left, thanks again for all the help!

 

[DirtyRed07]

I’ve successfully changed some of the font color. Anywhere with an html code i changed. Some of the lines just have “white” as the color in the line, will changing that to an html color code work?

 

[RandR+]

Ok so lets see here, I've been trying to use the YF-S401E flow meters but getting a lot of foam. I had them mounted as close to the keg as possible (where the 2cm hose is in this pic)

but I was getting a load of foam, here are 2 pours to show the difference!
With flow meter:


Without flow meter:


As you can see it's a huge difference, so I bought a bunch of loadcells and started printing the bottoms from this project Callwater/Beerkeg-load-cell to switch to weight instead.
So here's my questions, on the config page the pins are called "Command pin" and "Response pin" but the hx711 uses DT (data) and SCK (clock) so what goes where?
Second question is "Scale ratio", I'm guessing that it to tare or calibrate the load cells but I never found any information what to put there?

Thanks in advance and thanks for doing a great job with the software!
