HOWTO - Make a BrewPi Fermentation Controller For Cheap

[phishie]

Haha thanks guys, that makes sense.

It's a new Danby chest freezer so it comes pre-insulated.

1 degree gain over 12 hours? Quite frankly... hot damn. I wish I could keep my keezer/kegerator to 1 degree an hour some times.

Thats his beer, if hes doing 5 gallons and your fridge temp isnt way hotter i wouldnt expect that much thermal mass to change very quickly.

I'm trying to get a multiple chamber setup going. Chambers one and two are working smoothly. When I access chamber 3 website, I only get this screen. Anyone have any insight into this. I haven't been booted up for over a year...

I´m having an issue with programming my controllers, on multi chamber. I have Sainsmart Aruinos: http://www.ebay.com/itm/300948763268?_trksid=p2057872.m2749.l2648&ssPageName=STRK:MEBIDX:IT

When programming i get avrdude done. Thank you.
Then: There was an error while programming.

Any takes on how to overcome this?

Fwiw, I've never had luck programming from the BrewPi software. I've always had to use IDE connected to my laptop.

Are you trying to program with more than one Arduino plugged in? If so, do one at a time.

Have you been able figure this out? I had to redo my BrewPi over the weekend and now I'm having the same issue.

 

[wbarber69]

Are you using legacy branch?

 

[Rockn_M]

I don't think so.

 

[day_trippr]

You need that legacy branch if you're building around an Arduino...

Cheers!

 

[bscuderi]

Hopefully someone can help I corrupted some files playing with home automation so I started over and got a fresh start on everything. I used to have a stable brewpi so I can't figure out what I missed here. I have an audrino brewpi. I installed then ran the pi updater and changed over to legacy branch. I didn't try plugging in my brewpi to make sure it worked before I then set up the public and admin brewpi pages. I plugged it in tonight to the audrino and the python script won't start. And when I run the start command in terminal this is what I get View attachment ImageUploadedByHome Brew1485831127.082034.jpgView attachment ImageUploadedByHome Brew1485831149.449386.jpg

I was wondering if it was permissions based because of the error code but I wasn't sure how to fix it. You rock my socks thank you so much that worked

 

[day_trippr]

Excellent.
Now, backup your SD card!

Cheers!

 

[bscuderi]

Excellent.

Cheers!

First thing on the agenda! I had some backups but not any that hard all 3 things I want my pi running working so I decided to start over. I should update more often

I checked out the legacy branch and I'm having the same issue.

Been working on setting up my first BrewPi but I'm stuck at getting the Aruduino module to reply with version info. I'm using a clone module (Inland - UNO R3, ATMega-328-based ) and checking the board info with IDE, I got:
BN: Arduino/Genuino Uno
VID: 2341
PID: 0043
SN:75435353934351704230
Digging around on blogs seemed to indicate that the board name needs to match against the "known devices entry" in autoSerial.py. After editing to match the BN: string, rebooting and trying again, I can get the module programmed (Using Board Type: UNO, hex file:MEGA-dfu_and_usbserial_combined.hex and restore settings OFF) with the output below. During the attempt to "receive version number from controller", I only see Rcv activity and no Tx activity (hence the failure) Has anyone run across this and if so, were you able to resolve it?

Also, beginning to wonder if I'm just running into chipset compatibility issues and need to get a true Arduino UNO or a more compatible (Sainsmart?) clone. Any advice greatly appreciated.

From what I can find the Inland Uno is a complete R3 clone - hardware wise anyway - using the ATmega16R2 for the USB/serial bridge (most of the Uno clone issues have been with boards using CH340/341 bridge chips).

That said, if Inland burned unique IDs into the bridge (perhaps they didn't buy a license?) that would explain why there was a need to edit autoSerial.py.

Otherwise the board should be hardware compatible.

I'm not seeing any good clues in that log...

 

[gromitdj]

FYI: My Inland Uno R3 purchased from MicroCenter worked without issue.

(Using Board Type: UNO, hex file:MEGA-dfu_and_usbserial_combined.hex and restore settings OFF) with the output below. During the attempt to "receive version number from controller", I only see Rcv activity and no Tx activity (hence the failure) Has anyone run across this and if so, were you able to resolve it?

Why are you using the MEGA-dfu_and_usbserial_combined.hex file for an Arduino Mega and not the standard brewpi-arduino-uno-revC-0_2_10.hex file?

 

[mryeasty]

I initially tried it because the module packaging stated it used a ATMega328 processor. Additionally, because it was the only image that successfully loaded. The image you mentioned wasn't part of the current install package apparently (not present in the "firmwares" directory). I'll track it down and give it a try and see what I get.

 

[mryeasty]

Donny - Thanks for the pointer, brewpi-arduino-uno-revC-0_2_10.hex worked fine. Now, on to getting the wiring and packaging completed. -Dave-

 

[Bigdaddyale]

This looks interesting

[day_trippr]

It does indeed. It'll be interesting to see if they get enough traction in the marketplace to succeed.

The most evident issue is the lack of free GPIO.
And did anyone catch what architecture their core uses?

Curious base module pricing - the least capable version of the three is priced way higher than the other two?

Cheers!

https://en.wikipedia.org/wiki/Omega2_(computer)

Omega2 comes in two versions, the basic Omega2 and Omega2 Plus. Omega2 CPU is based on MIPS architecture[4] running at 580 MHz clock speed, equipped with 64 MB of RAM and 16 MB of flash memory. Omega2 Plus is similar to Omega2, except it has more RAM and memory and a MicroSD slot, sold for $9 USD. The system comes in a small PCB footprint with dual-in-line 16x2 pins. The board is designed to be Arduino-shield compatible, enabling one to make use the existing Arduino shields. The board runs at 3.3 volts of power with average power consumption of 0.6W.[5] Both devices are intended for as headless computers with no graphical interfaces in Embedded systems.

This is my first brew using the brewpi(converted an old UPS to house everything) and its maintaining the temperature very well. However, after a few days, my annotations went crazy. Everyone I hover over says 'changed to profile mode in menu'. However, since the start I've been using beer profile mode? Nothing has changed, why so many notices?

 

[wbarber69]

Got a pic of ur setup?

 

[riisefrutti]

Are there anyone on here who has tried to run a multi chamber solution with bluetooth or wifi?

 

[wbarber69]

You're first problem is that you have to move everything from var/www/ to var/www/html

 

[wbarber69]

And instead of symlinks to serial or kernel addresses, you have to use rfcomm* ports
