[Version 2 Release] RaspberryPints - Digital Taplist Solution

[day_trippr]

Github to the rescue!

It updated my local mirror and identified the updated flowmonitor.py as the only changed file.
So I copied that over to the RPi on top of the old version, restarted the flowmon service, et voila! I have sound in my earphones!
Well done!

Now I just have to figure out why it's going to the Analog Jack instead of the hdmi port.
This is now the only "junk" in rpints.log. Looks like my ALSA installation needs some love...

Did you hit Update or Get Latest RPints? Update just runs the update.sql script, but Get Latest RPints gets the latest from GitHub

I clicked Get Latest Update but now that I think of it I'm pretty sure I didn't then click the Update button. My bad

Cheers!

Analog Jack instead of the hdmi port.

While testing i ran into the same thing. Using raspi-config from terminal helped me:
Under system option->audio you can choose the output.

Inappropriate ioctl for device

Thats output from the command to wake up the monitor that i cant get surpress from my research
Not sure what the rest is.

 

[day_trippr]

I checked raspi-config to verify it was set to use hdmi stereo by default. It still doesn't
I wonder if the ALSA error is forcing audio out the jack.
I'll need to do some research on this but it's not an R'Pints problem.

Cheers!

 

[RandR+]

I wonder if the ALSA error is forcing audio out the jack.

That could be correct, the first thing i tried when testing audio was to add the sound menu and check if I could change output there, but that didnt work. But looking at the mixer from those settings it is ALSA

 

[day_trippr]

Which mixer is that? I just installed pavucontrol and it doesn't look like that at all.

Cheers!

 

[RandR+]

Which mixer is that?

Im not really sure, I installed VLC player and mpg321 to test my output outside of Rpints, but not sure if either one of those installed that or if thats the default Pi OS mixer.

I dont have anything for speakers plugged into my Pi to get sound normally. I did plug headphones in to test motion logic recently and thats it

 

[day_trippr]

If you can find an "About" for that mixer maybe it'll provide a clue.

For testing all of this I've been alternating between using the hdmi output to drive one of my three workstation monitors via its alternate DisplayPort input - but my monitors don't support sound - and using one of my office tv's hdmi inputs - which does support sound. I have verified I can push music to the tv hdmi input so I know the hardware works - under the right circumstances that aren't all that obvious sometimes

Cheers!

Best i got was to look up vesion information with
cat /proc/asound/version
which returned
Advanced Linux Sound Architecture Driver Version k5.10.103-v7+.

Seems like just a default driver to me

I would like to change the font colour of my RP installation (love it - thanks RandR+) from #A0A0A0 to #FFFFFF and have amended the /var/www/html/style.css accordingly but with a reboot it did not change so there must be another css file - anybody know where it is - I can right click on the font and inspect the file, amend it, but it doesn't save either.

 

[AI6K]

Have you tried clearing the cache?

Have you done a hard refresh? Hold down the shift button and refresh the page?

 

[LBussy]

Well hell - did not see your reply there.

 

[RandR+]

/var/www/html/style.css

Did you change both locations in style.css?

Try shift+F5, it could be cached on the old font

I just thought I'd have a go doing a scratch install (why not). RPi4B, loaded a new card with Bullseye, ran the install script. It completes with no errors, but no screen rotation, and no browser. The server is running, as I can log into it from another computer, but kiosk mode has not triggered. I have a feeling something must have changed since I last ran through this process.

I had the opposite problem and couldn't get out of Kiosk mode. Ideally I wanted to have kiosk display on one screen of raspberry Pi and other display used for brewfather etc.
I have managed to get Rpints working in a browser instead but not ideal as it has the browser margins showing.

Post 7701 might give you some clues as to where to look.

Try it.
Then use CTRL+ and CTRL- to changed the aspect ratio as desired...

Cheers!

Great I'll give that a go thank you.

@day_trippr

Would post 2643 still be the instructions for an install on a Pi 3b with a UNO R3 and adafruit flow meters, 64 bit Bullseye?

The link to website doesn't work anymore and I'm not sure how to start from scratch especially re the wiring of the flowmeters.

 

[RandR+]

2643

https://www.homebrewtalk.com/thread...-digital-taplist-solution.487694/post-8040187
That would be a starting point, but my version of RPints is much easier to install after getting Bullseye installed just run this from the terminal
curl -L https://raw.githubusercontent.com/rtlindne/RaspberryPints/master/util/installRaspberryPints | sudo bash

and follow the prompts.

 

[day_trippr]

Hah! I had to go look at that old post just for posterity's sake

Yes, that old version of R'Pints hasn't been viable for new installations in some number of years now.
Definitely go with @RandR+'s kit...

Cheers!

 

[DuncB]

Thank you @RandR+ and @day_trippr

Will the " automagick" install help me with the sketch? Install and the best info for wiring up the meters and Uno?

 

[day_trippr]

The installer is quite brilliant at everything except configuring your specific hardware set. It will even program the Arduino.

You can follow the wiring used for either an UNO (recommended by me) or an Alamode (though I use them they would not be my first choice today). Then it's just a matter of pawing your way through the various configurable settings, which isn't difficult. The real work imo is tailoring the CSS and html code for one's personal presentation aspects...

Cheers!

 

[RandR+]

sketch?

It will prompt you to select how the Uno is connected, which will be the USB option.
When install is done and the sketch will be uploaded automatically so no need to do anything with the sketch.

 

[DuncB]

Great news, it's raining so time to tinker.

Will be back with questions no doubt.

 

[DuncB]

I've got my hands on a couple of the sea brand water flow meters to try on raspberry pints. I can't at the moment find any 1/2 inch BSP to 5/16 adapters which I would need for the normal keg line 8mm external eva barrier tubing.
But I do have the 6mm EVA barrier tubing and can get 1/2 inch BSP to 1/4 inch adapters.

Any contraindications to using the narrower tubing? I realise line length will need adjusting using soltys calculator, I'd rather not use another adapter on each side of the flow meter to use the 8mm tube for testing and trial purposes.

When I changed my entire cold side (beer, gas, water, etc) to EVABarrier tubing and PTC fittings back in 2019 freshwatersystems.com became my go to vendor for the fittings.

Thanks, think I might have to play with the narrower diameter connectors and tube to start with and then if not useful will order from Australia as they seem to be the closest supplier with the connector.
