Yeah, the link's automatically redirecting to us.diybeer.com which doesn't have that page... So much for the internet being international, huh?

Yeah, from about 950 psi (65 bar) to 550 (38 bar) at those temps. I just double checked my regulator, and the red zone starts down at 30 bar, so I blame your regular starting it at 40 for scaring you...

I've been happy with this one. It's extremely similar to the one day_trippr posted, but a bit less expesive. https://www.amazon.com/gp/product/B00KYA0RC2/ As for a vittles vault alternative, look for a gamma lid, which is the same screw top air tight seal as the vittles vault, but for a bucket...

I'm working on some software for an iSpindel (which uses a WiFi ESP8266 based board) right now, and those take an 18650 battery, which is not a whole lot bigger than a AA battery (65mm vs 50 mm tall, and 17 vs 13 mm diameter). They're nominally a 3.7 volt battery, but at full charge get up to...

In the setup I was describing (no wires, fully contained along with a battery inside the keg), the device sleeps for that hour to save battery then wakes up to read the sensor and push to your server/logging interface. Because it's locked away inside the keg, there's no way to wake it from...

Yeah, just sounds like we have different goals. I don't care to catch each and every pour, I just want a ballpark of how low the keg is. Even missing 4 pints is only half a gallon (10% of the keg), and I'm fine with that. A sudden dip in my graph showing it went from 3 to 2.5 gallons since the...

I'd think waking up and checking every so often (e.g. iSpindel style) should work just fine. Unless you've got a bunch of people over drinking, every 30-60 minutes should be way more than enough. At least in my use case, I'm not looking for real time data, I'd just want to know when a keg is...

Yeah, a D1 plus antenna inside the keg should help. I'm also about to upgrade a mesh WiFi, so perhaps it wouldn't be as big of an issue with a closer AP anyways.

Depends on how sexy the wiring job is... He did say there was a temp and pressure sensor in there as well, so I was mostly curious how it was all working in that box on only 4 pins. Could be an ESP type board in the box, but with I2C I guess they could all be on the same 4 with logic in the...

I'm really curious to see what's going on inside the box!

Yeah, pretty simple, and everything can be easily found at Radio Shack. I'm on my phone now, so no part numbers, but they're all simple parts. The 555 is under $4, and everything else is under $1. (The potentiometer may be $2-$3 at RS...) Total under $10, plus some simple soldering work. I'm...

Yup, that's what I thought... Mostly wanted to clear it up for the sake of those who come later. My NPN I thought was rated to 800mA, so really no idea what's going on here. No worries, I need a trip to Radio Shack for perfboard anyways, I'll grab a MOSFET while I'm there. Oh, and I tried...

Oh sure, now that I've got it all breadboarded out... Got it running though, substituted a 2n2222 for the MOSFET as suggested, and it runs nicely. I really appreciate your build diagram, that'll make it much easier when moving to perfboard; the breadboard gets kinda crowded with jumper wires...

When I saw the title of this thread I thought "Why would you use PWM for your stirplate, that's just overkill!" but this makes a lot of sense... I'm right there with you on being bugged by losing the lower end of the speed range, and it's really not that much more complicated than the other...

Also, did you take a hydrometer reading before racking onto the blueberries? There's sugar in fruit, which is bringing up your current reading. You could have been down to 1.012 before "adding" the fruit sugars, which brought it back up to 1.016. (There is no way to know what the number really...

Shipyard Imperial Porter. Up next is bottle 6 of my first batch (bottled 5 weeks ago, and starting to taste mighty good)

Guess I'll be that someone... What you've got there is a braggot. http://mead.bravehost.com/braggot.html I even believe your honey should be nearly 100% fermentable, with the malt probably closer to 75%, so your ratios look to give you pretty much a 50/50 mix of fermentables from honey...

Cooler temps may slow down carbonation, but that's not nearly cold enough to prevent carbonation completely.

You beat me to it. I was wondering if that method was good for beer too though. That thread is for Cider. I have no idea what heat pasteurizing beer after carbonation will do to the flavor...
