Intruduction

The “iBLOPPER” is rather simple to build and a solder free version can be build for 15-20 EUR/Dollars. Else 2 solder-versions can be build for 10-12 EUR/Dollars with only 7-11 rather simple solderings. Both versions can be build from common and easy available Arduino electronics.

iBLOPPER "None-solder" version based on Grove - IMU 9DOF v2.0. Here the NodeMCU "lolin" is packed away in a Tick-Tack Box. The IMU sensor should be protected by a small baloon to ensure blow-out do not harm it.

The iBLOPPER is an Arduino device (ESP8266). It monitor your yeast activity by motioning the CO2 blops pr. minute (BPM). Besides BPM, also “Sum blops/L” and temperature is logged. Based on Sum Blops/L indicative gravity estimate is given by polynomial/modelistic approach.

It works by placing iBLOPPER on the outside of the airlock, and iBLOPPER then detects the tiny movement the airlock makes at the release of a bubble. Hence, it need placed away from vibrations sources (flamingo mat in cooler or similarly).

The software can though the “Sum Blops/L” be used to give an indicative SG/rG (reduction in gravity) by polynomial approach. To ensure a reliable SG estimation and to account for the many factors affecting CO2 release the users needs to conduct a midterm “one hydrometer reading” when preferably high kreuzen has just passed and hence re-calculating and updating the polynomial for the current brew by simple maths.

Hence, the idea of iBLOPPER is to simply adding one more hydrometer reading on top of the OG, and the 2 FG measurement we all recommend. This 4th sampling at preferably just after high kreuzen can tell us something about the speed of fermentation, thus, giving us an indicative estimate of the SG. All while we monitor on the outside of fermenter.

iBLOPPER "Box version" (D1 mini build)

Video´s of soldered version of iBLOPPER. Notice an none-solder version also is possbile.

And following video shows have to build:

How to build (solder version), install and setup.

iBLOPPER “NodeMCU version” solderfree.

A solder free version can be build even a bit more expensive if making use of Grove – IMU 9DOF v2.0 insteed of a MPU6505. If also using a shield for D18B20 temperature probe, you can build a iBLOPPER without any soldering at all based on below diagram, etc. You will also need one “GROVE – 4 PIN FEMALE JUMPER TO GROVE 4 PIN CONVERSION CABLE”. This version will be a bit more expensive, around 15-20 EUR/Dollars vs. the 10-12, for the soldering version

Grove – IMU 9DOF v2.0 insteed of a MPU6505 (for people downunder "PiicoDev Motion Sensor MPU-6050" might be an alternative. Not tested as the are not sold in DK so far).

Temperature probe ds18b20 including shield.

iBLOPPER “None-solder” version based on Grove – IMU 9DOF v2.0 and DFRobot Gravity – DS18B20 temperature sensor as this one is so easy attached at D0, D1 and D2.

iBLOPPER also works fine with other types of airlocks, even not tested in full. Here with Grove – IMU 9DOF v2.0 and DFRobot Gravity – DS18B20 temperature sensor.

Diagram for iBLOPPER for NodeMCU. Please notice you can make use of 3.pin temperature shields as "DFRobot Gravity - DS18B20 temperature sensor", or "Iduino SE029" as D0 is turned low (equals ground) and D1 turned high (equals 3v3).

iBLOPPER “None-solder” version based on Grove – IMU 9DOF v2.0. Here the NodeMCU “lolin” is packed away in a Tick-Tack Box. The IMU sensor should be protected by a small baloon to ensure blow-out do not harm it.

Alternative till Grove IMU 9DOF v2.0 sensor, you might also make use of Adafruit MPU-6050 6-DoF Accel and Gyro Sensor + connector 15 cm. Downunder Australia “PiicoDev Motion Sensor MPU-6050” is sold + connector 20cm.

iBLOPPER CLOUD

All data is uploaded till iBLOPPER CLOUD and all controlling of the logging process is handled at iBLOPPER CLOUD. Hence, please register with your 7-8 cipher unique iBLOPPER Number at iBLOPPER CLOUD.

At the CLOUD you can set brew name, size, OG and polynomial for speed of fermentation. You can ofcouse start, stop and delete logged brews.

You can change setting for Fahrenheit, set time zone and forward the current Active Brew till Brewfather or Brewersfriend if you wish.

It is also possible to send your iSPINDEL data till iBLOPPER CLOUD and hence join these dataset together of gravity from angle detection joint together with iBLOPPER activity data. See more at https://iblopper.bubble-logger.com/2352-2/.

iBLOPPER CLOUD do also support the control of “TempControl for iBLOPPER CLOUD” and hence let you control the fermentation temperature, see more at https://iblopper.bubble-logger.com/2111-2/ .

iBLOPPER CLOUD is a crude installment for a CLOUD service, but continuedly work is planned.

EXPANDED TECHNICAL DETAILS

Scientific Brewing Automation

The iBLOPPER is a specialized IoT device for homebrewers that monitors the "Activity" (bubble count) in a fermentation airlock to track the progress of yeast.

Bubble Counter Sensor: Uses an Infrared (IR) beam-break sensor or an acoustic sensor placed in the airlock. Every time a bubble of CO2 passes through, the Arduino records a "Blop" with a millisecond timestamp.
Fermentation Rate Analysis: By calculating the frequency of bubbles over time, the ESP8266/ESP32 can accurately predict when the fermentation has finished and even estimate the current Alcohol by Volume (ABV).

IoT Integration

Cloud Dashboard: Data is synced to the iBLOPPER Cloud via WiFi. Brewers can view a live graph of their beer's activity on their phone, receiving notification if the temperature spikes or if the fermentation unexpectedly stalls.
