About Us

Welcome til iBLOPPER

formerly known as “The Bubble Logger Project”!

This site started as an Arduino project to see if one could use a cheap sound sensor and cheap Arduino CPU till measure the activity when fermenting including foresee gravity. It originate back till 2018 or so where the first Bubble Loggers builds was posted.

Over the time and especially during the Corona times I ventured into making SBL4TILT“, there combines the sound sensor and TILT repetition. Later last year I developed “Bubble Logger SPINDEL + CONNECT there is alternative till Ispindel/TILT, but includes activity measurement also by sound detection.

But the original idea of estimating SG from CO2 bubble release never died and hence iBLOPPER is active again for both vibration detection and the older sound detection version.

All above was basically started as both TILT and PLATTO was so expensive. Hence the goal of iBLOPPER is to give the homebrewer a cheap way to measure activity, temperature and gravity by not emerging anything into the wort. Secondly, it should look good/ok, be easy to build/handle, and especially the cost should not be high if ever commercialized. Hence, the only way not to end up with a high price is to go down the road of letting the user build themselves = BuildersWare!

Terms and Values

iBLOPPER is free to use and test by the “free” license renewed quarterly, e.g 31 March, 31 June, 31 September, and then 31 December (or roughly dates). Hence, not to get decapitated logging, remember these dates….or…..support us by buy you own sole license supporting 2 devices (any combination of the builds listed).

We sell the iBLOPPER license as a hobby project, under the Danish rules for this.

We offer further to the “test for free” a money back guarantee of 30 days, e.g. the price subtracted by the Paypal fee. This equals 15 EUR of the full price of 20 EUR for the license, and in this case the license will be reworked.

This site and these Arduino builds is done for the sole reason of fun.

Who am behind iBLOPPER/Bubble Logger Project and Testimonial!

My name is Klaus and I am a 47 years old passionate homebrewer with education in Agriculture/Microbiology/Chemistry. I have a long time interest in programming, science and homepages, and all is more less “brewed” into this project of iBLOPPER/”The Bubble Logger Project”. The idea (testimonial) is to prove and show the use of BPM both as a graphical mean for fermentation progression, but also the Sum BLOPS can be translated into a a meaningful SG estimate if the users do a hydrometer reading during brewing, e.g. measure the current brew “speed of fermentation”/scaling factor.
