The polynomial inbuilt in the Bubble-logger predates the Logger started to report “Sum BPM/L” and hence the “Sum BPM/L” was back then calculated in Excel during the process of building the model. As the model takes into account the surrounding pressure and the temperature of… Read More »Updating the polynomial!
People following this site will noticed I abended the inferred detection I have been working on and tested. It was abended as the sensor quality was low, and out of the 8-9 I brought only 1-2 was counting/detecting bubbles near to hear and see count.… Read More »Yoga Pilsner ver3 (Inferred detection).
I have looked a bit at the dynamics of airlocks and how the bubbling generation rate is connected till the airlocks. I got 4 different S-airlocks where of 3 seems very similarly and one is very different. To get steady bubbling rate I used a… Read More »Airlocks dynamics
I have worked on a inferred version of my bubble logger, but as the sensor is of various quality and hold no way of calibration I have stooped further development of the inferred version. Secondly, the inferred sensors very easily breaks, and especially if you… Read More »Inferred Sensor build (disconnected).
In the 3rd experiment I will try hold the sound Bubble Logger up against the inferred version. As stated a bit in “Theory behind the project” I have so far tested one sound sensor and 2 different inferred sensor (of same type), and hence, the… Read More »Exp.3: “NEIPA – When to dry hop if using Vitality starter (Sound vs. Inferred detection?)
The second experiment posted on Bubble-Logger.com blog we wish to compare the use of vitality starter vs. directly pitch of 5g dry yeast. For both batches we make use of 5g dry yeast and for our Vitality starter this was started 24h prior to direct… Read More »Exp.2. “5g Dry Yeast directly added vs. 5g Vitality started”
The first experiment on “The Bubble Logger Project” blog is to compare the yeast pitching rate. The Bubble Logger give both yeast activity measurements and SG estimate, hence, we will have good details on how the fermentation is affected by high or low amount of… Read More »Exp.1: “Yeast amount comparison – 300ml Vitallity starter vs. 1200 ml Vitallity starter”
