The second brew done with “Bubble Logger SPINDEL”, and this brew is done with only 10-15% headspace. As the Classic Munich Yeast is rather explosive I was aware this needed to be done with blow-out, and as such first real brew using blow-out. OG =… Read More »2nd SPINDEL brew: “Common Wheat” October 2020.
This is the first real “Bubble Logger SPINDEL” brew and done in September 2020 in the 10L Speidel fermenter. Before, this brew a few suger-dilution brews was done and test with a putting pressure into the fermnters by aquarium pump. In this brew we got… Read More »1st SPINDEL brew: NEIPA September2020
The newest build is now online: www.bubble-logger.com
The new build of the Bubble Logger Project is up and now live. I have worked on joining all the things together I have been “playing” around with TILT repeating. Hence, the Bubble-Logger Project is now moved till ESP32 and monitor your fermentation and control… Read More »New Build – SBL4TILT “Sound Bubble Logger and Temperature controller for TILT” + light version
Components needed To build a Bubble logger you will need: one NodeMCU Version3.x costing around 3.5$ one ds18b20 probe + shield temperature probe (including a resistor 4,7K ohm) and attached it on pin 02 (D4) of NodeMCU, in all a price of 3$ one Sound… Read More »Obsolete: NodeMCU (ESP8266) Sound Bubble Logger (disconnected).
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 »Obsolete: 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”
