Sound good. I do have another chip (done enough DIY of varying sorts that I do try to have spares, cost permitting), so I'll put that in and see what happens with the LCD. Since everything seems to be working, I'll get a test bucket set up and start playing with it a bit. Once I get a handle...

Cool - thanks, both. Going to do a couple of experiments, I think. If I get anything I think is useful, I'll post back.

OK - progress! Have three probes connected now, set to beer, fridge, and room. Running in Beer Constant, I can get the cool side to kick on immediately when I set the temperature below where the beer probe is reading (same is true if I run a Fridge Constant). Heating seems a little...

Great information, thanks! Like the pressure gauge set up as well. May be on my next project list.... Appreciate it!

Ahhh - sorry, misunderstood that. I'll test it with multiple probes tonight and see what happens. Likewise will fiddle with the shield pot - you are correct that the references I was seeing were for I2C - I knew they didn't necessarily apply, but still thought I was supposed to be looking for...

Well, at least I've got something... Right now I have one temp probe set up, assigned to Chamber 1, Beer 1, and Beer Temp in Device Slot 0. Temp reading is 74F, running Beer Constant set at 60F, so cooler side should be coming on, but nothing's happening at the relay. Same is true if I...

OK - spoke too fast - I was getting cooler power because I somehow set that pin to "not inverted" - experimented with both of them, and "not inverted" turns both on. Still not getting anything when they're properly set - here are the current settings (one temp probe is on Device Slot 0)...

Geez - you guys are fast! It was simpler (and dumber) than that - I didn't realize I had to set the heater and cooler devices in the config menu. Set those, applied the setting, and the tester I had plugged into the socket popped right on. Testing the heating side now - but looks like it will...

Wait, wait! Found the chamber heater and cooler assignments - now I'm getting power! Woo hoo!

Well that's intuitive! :) OK - had a chance to start playing again - now the shield is fixed, I'm using that. Once I had some patience and made sure everything was set in the menus, the probe has been detected and it's reading a good temperature. Now the issue seems to be the relay. I've got...

Wasn't sure whether this is best in the fermentation, bottling, or cider forums, but I'll take a stab here first since it relates to bottle conditioning. I know some of this question depends on the health of the yeast in question, but for the sake of argument, assuming the yeast populations are...

#1 - hah, that did it. Arduino stays on, RPI stays functioning, interface says script is running. Out of curiosity, how would I know which pin on the shift register is Pin 1? There are no markings other than a part number on it - should I have just made sure the part number was right-side up...

Thanks - not sure why that never really occurred to me, but it seemed so simple that I thought I must be wrong for some reason. I'm continually finding that this hobby isn't always as complicated as I make it sometimes. And you can rest easy - the 4.5 vols was just an example...that would a...

If you want the short version of this - is it reasonable to use the grams of sugar in the frozen concentrate's nutritional info to calculate the amount of "priming sugar" you're adding to a batch for bottle conditioning? Assuming that's fine, then simply pasteurizing before it fully conditions...

Hello, all! Said this on another thread, but thanks in advance for everything on this thread and others related to this project. I'm fumbling my way through it, and I've gotten farther than I would have expected just by looking at all the previous work. I've got two issues now that I need...

Great! Thanks for the help!

OK - I've figured out enough to get myself to the point where I know I don't know enough to keep going, so it's time to seek some guidance. First off, the amount of work you guys have put into this project is mind boggling. I've been lurking for a while and sifting through everything, and...

I'm working my way through a bag of Proximity Pale Ale malt while trying to zero in my techniques (keeping a very basic recipe and trying to get some consistency in process and outcome, while trying out some different hops). I've been really happy with it, with the caveat that this is my first...

I have something weird going on with one of my recent brews (at least it's weird in my 1-2 years of experience). I made a partial mash oatmeal stout (recipe below) and bottled it in mid-June. I used carbonation drops, mostly because I've got a lot of them and am trying to use them up. Haven't...

Anyone know anything about this company or it's products? It showed up in a marketplace app i have. Two main products - an automated brewing system called Beerdroid and a small scale tap/dispenser called Beerflo. I'm a small batch brewer, so the Beerflo is intriguing, but can't find anything...
