Full project can been seen on: www.iBLOPPER.bubble-logger.com <h3 >Intruduction</h3>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.<div class="se-component se-video-container __se__float-none" contenteditable="false" style="width: 100%;"><figure style="width: 100%; height: 56.25%; padding-bottom: 56.25%; margin: 0px;"><iframe frameborder="0" allowfullscreen="" src="https://www.youtube.com/embed/0gT70VbIQTk" data-proportion="true" data-percentage="100%,56.25%" data-size="100%,56.25%" data-align="none" style="width: 100%; height: 100%;" data-index="0" data-file-size="0" data-origin="100%,56.25%"></iframe><figcaption contenteditable="true"><div>iBLOPPER "None-solder" version based on Grove - IMU 9DOF v2.0.

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.<h3 >iBLOPPER &#34;Box version&#34; (D1 mini build)</h3><figure><img src=https://projects.arduinocontent.cc/2a943aee-efea-49fb-9288-4c0787f834c1.png /><figcaption> </figcaption></figure><div class="se-component se-video-container __se__float-none" contenteditable="false" style="width: 100%;"><figure style="width: 100%; height: 56.25%; padding-bottom: 56.25%; margin: 0px;"><iframe frameborder="0" allowfullscreen="" src="https://www.youtube.com/embed/D_m3dha7uLg" data-proportion="true" data-percentage="100%,56.25%" data-size="100%,56.25%" data-align="none" style="width: 100%; height: 100%;" data-index="0" data-file-size="0" data-origin="100%,56.25%"></iframe><figcaption contenteditable="true"><div>Video´s of soldered version of iBLOPPER.

iBLOPPER - a fermentation logger for homebrewing!

iBLOPPER is activity fermentation logger to be attached to your (S)airlock. It works by detecting tiny vibration when a bubble is released.
