Thanks for the shout out. I'm glad someone else found that design useful!
What are you looking for? I have one of the 1st generation PCB's and the parts to populate it - with an LCD too. PM meBeen lurking around for a little while now. I've got the basic BrewPi wired up and running fine, and now I'm looking to add the LCD and rest of the fun bits. Would anyone happen to have a board laying around still? Compensation will be given of course.
Hey there, @matridium, welcome to this corner of the world. Good luck on your build. If you have questions or issues during the process, feel free to post them as there are quite a few knowledgeable folks here eager to help.Hello.
I have been following this thread now for about three weeks, reading up on the LCD shield. I have yet to build a brewpi, however I have started to order most of the parts needed. I am a little confused at this point as to what the best version of the shield is going to be to build.
I see three version at this point maybe 4? I downloaded from the Google docs folder BrewPi Shield v2.0, and I started to build an order on Mouser and I noticed this must be a shield a nano? I have found the DIYBrewpi WIKI very useful.
Unfortunately I have already ordered the regular arduino the resistors and 2 channel relay board therefore
I think if I get these questions answered I can better deiced on what I need to do next before I purchase more things then I really need.
-Does version 2.0 of the shield take care of LCD display issues (scrambling)?
-Should I just build version 1.2 (regular Arduino) because I'm already getting that kind of board?
-If I go with v2.0, and use a nano, should I buy a real Nano from Arduino, or just anyone on Amazon, I know drivers are issues with counterfeits.
-What is the best LCD board to order? I see lots of them but I want to use good quality parts?
-Is it advisable to use the SSR or is the 2 channel relay fine? (I have a small refrigerator, I have not looked at wattage but I think its well within the range of the 2 channel board)
-I have no problem getting the boards made on OSH Park, and if anyone is interested in the boards I can put more boards on my order and send them to anyone who wants one.
If there is any other info that will help me that I did not mention here please let me know.

I never resolved the scrambling with my arduino version, if you’ve not ordered yet, it might be worth taking a look at Fermentrack. It’s based on Brewpi and uses a Raspberry Pi, and functions in a identical way, but is still being supported.
It’s what I have moved too, although there really was no issue with the original Brewpi, I think there is a little less soldering on Fermentrack
I recommend going to Fermentrack, too, but to clarify, Fermentrack replaces the website software side of Brewpi, not the hardware side. @Thorrak ported the Arduino code over to an ESP8266 that has onboard Wifi, and he created an interface so that the LCD with the i2c backpack could be used. @Mikmonken is 100% correct that there is a lot less soldering involved with that solution and it is a great way to go. I have 4 units running, 2 of which are the original Arduino versions with the shields, and two of which are the 8266 versions. Both work great. But Fermentrack will work on either solution.I never resolved the scrambling with my arduino version, if you’ve not ordered yet, it might be worth taking a look at Fermentrack.

Great for all the help guys!
I’m going to look into the fermentrack software sounds interesting. Only thing I have on order is a rpi and Arduino UNO sainsmart relay board and sensors and resistors. I have not ordered anything for the LCD shield since it looked like it was still evolving and I needed questions answered. What’s needed to move to the fermentrack software past what I already have on order? Also just a small note on my background. I’m a biologist and I run a microscopy core facility so I have access to some very high end microscopes. But my hobby for the past 18 years is a small machine shop in my house. I have almost anything you can think of in a machine shop spare a few machines. I can probably help manufacture items for brewing for anyone who’s interested.. my latest toy is a laser cutter/engraver..
anyway brewing has been an on-off hobby of mine for many years but now I’m really getting back into it and have really taken to the fermentation control and tracking stuff.
How much voltage is going to the LCD?I had what looks to be the same problem.I had to bump up the voltage to 9v and turn the pot 20 revs in each direction before it would read.What am I missing? I have the shield 1.2 all soldered up and mated to the Uno. The probes all connected, relay connected, LCDs wired and flashed via fermentrack. The LCD pins are connected from 1-16 to 1-16 on the shield. The LCD is lit but nothing on it. It is recognized on fermentrack. I turn the know on the trimmer but nothing.
What am I missing?
Ok -Good luckThe Uno is running off it's own power supply. So it should be plenty power.
What about flipping the text 180 degrees? I did a search through this thread and nothing came up.Nope, that's really your only option. You can separate all of the wires to make it more flexible, but that makes it a pain to hook up. You can also ditch the middle four wires because they are not needed, but again, using all of them makes it easier to align the wires.
Is that bad? I mean if I mount the screen uosidu down is there a way to change the text orientation? I might not need an answer because the project boxes I cut out today .....I messed up so I need to start over.UhWhut?

OP doesn't want to stand on his head to read the display.I'm trying to picture the problem...and drawing a blank...
