[Initial Release] RaspberryPints - Digital Taplist Solution

[billybryson54]

I'd like that info as my pi keeps disconnecting from my network.



Sent from my iPhone using the sweet Home Brew app, cuz I'm a ****** and I need everyone to know that I have an iPhone as if everyone else in the world doesn't have one.

Sorry for the delay, the last few nights have been a lot crazier than I thought they were going to be. Anyway, yes. My wifi issue seems to have been solved. I just added a few lines of code to disable the power savings feature, and to automatically ping my router every so often.

Open lx terminal and type:

sudo nano /etc/modprobe.d/8192cu.conf

Inside of that file, I added the following two lines;

# Disable power saving
options 8192cu rtw_power_mgnt=0 rtw_enusbss=0

Save and exit, and then type

crontab -e

From there I scrolled all the way to the bottom and added this line;
*/1 * * * * ping -c 1 192.168.0.254

The IP address in that last line should be entered as the IP address of your wireless router.

Then finally, reboot your Pi

I'm not going to take the credit for this, I found this out after a bit of google searching. However, since I did it, I have not had one single connectivity issue for over a week now. It should be noted that this set of instructions was meant for the edimax dongle but since that's what I currently have, I didn't look further. Hope this helps. Let me know if it does or not.

You will definitely have to use the barb connector with Bevflex 200 since the OD is a touch to big.

The part number for the barb connector is: PI1251208S that's the 3/8 insert with a 1/4 barb.

You have an extra "1" in there but it got me started! Thanks very much for that, I wasn't making any headway until now!

So PI251208S is the 3/8" tube to 1/4" hose barb. Excellent! Found it on Amazon but with a 2-4 week lead time I'll keep looking around.

And I think I finally found the 3/8" female BSP to 3/8" tube connector. It's JG part number PI451213S.

Look right to anyone that's been there/done this?

Cheers!

 

[mcangeli]

That looks right, but I was able to use the ones on it with barbs that I got from freshwatersystems.

I'll see if I can find the link.

Day check http://www.freshwatersystems.com/p-2485-stem-barb-connector-38-od-stem-x-516-id-barb.aspx (those are the ones I have but they should have others and better lead time)

 

[day_trippr]

[...]We're also looking at expanding the number of pins available by adding a third shield on top of the alamode, but thats further down the line.

My Centipede suddenly looked hopeful

By the way, how many taps can 'Pints handle without a Centipede?

is my current tap list. Its live with the flow meters on it.[...]

That...is...awesome!

Very exciting times!

Cheers!

Off the top of my head... 10? (I'd have to count when I get home)

Thanks a lot for that lead!

I need parts for 6 faucets to start, plus a couple of spares, and Freshwater Systems will sell me 14 pieces of the barb adapter for less than getting stuck buying ten packs on Amazon and having a lot of leftovers.

I received email from the ebay flow meter seller confirming that the fittings for 3/8" OD tubing are included (yay! Saves me around $50!) so I just ordered the barbed adapters. Meters could be here by Friday but probably Monday, hopefully these guys can get the plastic bits up here from SC by then!

Thanks again!

Cheers!

When my meters were delivered they came with those attached so all I needed was the insert to 1/4" barb. You may want to check before spending money on the other connectors.

Thanks! Yes, I did just that (posted a few replies back) to confirm the BSP adapters were included, so I only ordered the barbed adapters.

Also ordered another SD card to speed up recovery when I break stuff

Cheers!

[edit] I found a really informative write-up on the SF-800 meters. It preempted a metric crap ton of questions I'd have bugged everyone with And looking at those cables I'm thinking I'll build a patch board to go from the meter cables to a VGA 15 pin D-SUB bulkhead connector to exit the rear edge of my keezer's lid and make a twisted pair cable up to get to the AlaMode...

 

[wbarber69]

For the flow meters yes.

The meters are hooked directly to the alamode which is serving as the arduino processor for this. I don't believe the pi can get the data from the flow meters with out it.

We're also looking at expanding the number of pins available by adding a third shield on top of the alamode, but thats further down the line.

http://rp.skypainterbrewing.com
is my current tap list. Its live with the flow meters on it. I've also added the untappd brewery feed for my "brewery" (did you know that homebrewers can add their brewery and beer to untappd?) and its pulling the rating and the beer label.

It also automatically posts to untappd for me when a pint is poured. I haven't figured out how to handle guests yet, but I do see some kind of rfid project in the future and fobs for my friends/guests...

I meant is the alamode a requirement over using an uno or other arduino. Like I said before running cables to the alamode will require a 50' run. If I can put the arduino where the flow meters are I can run a USB over cat6 extender to the pi. Plus I've got plenty of UNOs lying around.

 

[day_trippr]

fwiw, I requested Arduino-interface-agnosticity (hmm...yeah, that works ) on the 'Pints site months ago, although I really do like the AlaMode implementation. It's a nice compact package, though clearly it doesn't fit your specific partitioning needs.

But you may just luck out in the end: the AlaMode commits a bunch of AVR pins to providing interfaces to its Real Time Clock chip (a square wave pin and an I2C pair) as well as a boatload of purposed sockets and headers. It's that RTC interface pin usage conflict that plagued my attempts to get BrewPi to run on the AlaMode.

The "boatload" of AVR pins presumably won't be used (or usable) for their intended purposes, so as to allow them to be available to R'Pints, but the RTC interface pins are decidedly unusable by 'Pints. So the available AVR pin set on an Uno will be a superset of the AlaMode implementation. As long as you can steer the device communication to use a USB port ttyACM(n) instead of the serial port ttyAMA0 there's every reason to believe it'll work just fine...

Cheers!

It *should* work with other boards as long as they're arduino based. However, the alamode is the one that we're developing and testing and setting up on so as far as making it work on the other boards you're kind of on your own.

FYI Use Coupon SHAREBTL on freshwatersystems.com for a free water bottle

 

[day_trippr]

Another one? I tried a few coupons for free shipping with no joy - nothing was actually applicable to random plastic bits.

So...thinking about how to get from meters to AlaMode, here's what I've come up with so far. 3 pin mini XLRs on the meters to latching receptacles on a small panel I'll attach through my keezer lid liner, specific location as allowed by the meter lead lengths.

The backside of the panel will be transitional hard wiring that will lead to a 15 pin D-Sub cut through the rear of the lid (joining all the other connectors and gas bulkheads back there) to a fabricated mating cable leading to Dupont terminations for the AlaMode. Data will travel over twisted pairs, 5VDC power and DC return over dedicated/larger gauge wires.

The two gating factors will be the length of the 3 conductor cables that show up with the meters, and whether I can cram the ends into a mini XLR housing (Swissflow used some beefy looking wire for these things)...

Cheers!

I have bev seal 235 installed in my kegerator. 3/16 ID 5/16 OD. The swiss flow meter is a 3/8 male thread. Anybody know where I can get a 5/16 x 3/8 BSPP john guest fitting? (actually, 16 because I have 8 taps). Mine all came with the 3/8x3/8 JG fittings as well, but I haven't seen a 3/8 straight x 5/16 fitting either.

Also, how many meters does one alamode support?

 

[wbarber69]

When I get home I'll post the link to the mini xlr's I just got. They have a much bigger mounting hole. Are all metal and cost the same as the little cheapos

[edit - posted wrong item]

One of these might work - if the stem end is the 3/8".

thanks for the link, but I really want push connect for my beer line, not barbed. Thats the whole reason I went over to the bev seal line....

If i can get those fittings, I will alpha test 8 for everybody

 

[TrickyDick]

OK looking forward to getting this setup!

Question #1

Setting up with a hardwired Ethernet cable, but want to use a USB Wifi adapter once its setup to make edits.

How/where do I access the wifi USB adapter to be able to enter the network password??

Thanks!

Sorry, I posted the wrong item. I changed the link to what looks like a 3/8" stem to 5/16" OD tube adapter that should plug into the existing fittings.

Pricey as the dickens, but compared to trying to get that tubing over a barb, it's probably worth it...

Cheers!

You can go this route from the local display (if you have one)

or go this route from a Putty session if you're headless...

Cheers!

 

[winovino]

for anyone who ordered the refurb flow meters from ebay in the past few days i have a bit of info.
i messaged the seller asking if he knew what the previous use of the meters was. here is his response:

"Their primary use was beer. They are food grade and have been cleaned and refurbished. I have so many that it's hard to tell which ones were used and which ones are new. Depending on how many you order you'll usually get a mixed batch.

- nvd85"
so who knows. some of us may be getting new meters....

 

[winovino]

and not to rub it in, but i ordered 4 before i posted on here about the availability and he accepted 19$ each

Thanks! Actually, came to $30 to order 18 of them (couple spares plus shipping). They always give a big price break at the 10 qty mark

 

[DrunkleJon]

Since everybody seems to be buying up their parts now I find myself being lazy and wondering if anyone has found the best (read speedy and cheap) source for the a la mode? I asked Mr. Google and he only gave me two places to order it from, otherwise d'ya think a bulk order would possibly be arrangable/actually worth it?

 

[machfive55]

Quick question. I'm looking to do some keg level monitoring using another method (other than flow meters). I got Raspberry Pints to display the keg level, but now what do I need to update/change to get that image to change on the screen. Is there a script or do I manually have to update the db? How do I do this, I don't see the obvious answer here.

 

[wbarber69]

Should be able to set up a cron job to handle updating the script.

 

[machfive55]

That would work, but I need to know what fields or values to change to update the keg level.
