Because: $8.99+ No Import Fees Deposit & $8.57 Shipping to CanadaHow about the real thing?
That's what someone needs to build, is something that goes between the fermenter bung and the traditional airlock that has the brew bubbles sensor on it. This "something" could be 3D printed and "regulates" the size of each bubble, so the counts can be used to calculate the volume of CO2 expelled...And all that said - I was having a conversation with another unnamed co-conspirator (right @UncleD ?) about how the platform really does not need to be tied to the board and sensor I have here. I wanted to release a functional proof of concept and I was hoping someone would figure out a way to maybe meter the bubbles evenly (and emulate SG like Pl**to), or use a flow meter like @day_trippr is talking about. Anything could work, Brew Bubbles just counts pulses. I did not use a more expensive flowmeter because this was $4 and those are ... well, more.
James are you in Canada? Maybe there's someone semi-local who can print a bracket for you? Not sure what shipping is to Canada from here.
For me BrewBubbles is an "indicator" as how the fermentation is progressing rather than a "meter" for how the fermentation is progressing. For example, I have a WineXperts 23l Chilean Malbec fermenting away in a plastic fermentation bucket and plastic lid. You can see the lid move as the pressure is relieved! The bubbles come along in bursts and sometimes no (or very few) bubbles pass the sensor when it's really active and sometimes I get multiple edges of water as the gass moves pass....With all the fiddling I have done I haven't been able to find an arrangement that gives less than about 3X the actual BPM...
Yes, I'm in Canada. I have a 3d printer, but I'm using a sensor module like the one below and I don't think it will fit in the standard Brewbubbles bracket. I will print one anyway since I have a standard PCB and sensor on the way now I hopeJames are you in Canada? Maybe there's someone semi-local who can print a bracket for you?

I was asleep, alone in the house, and the boards are wedged pretty solidly in the bracket. Also moving it on purpose this morning didn't make much difference so I didn't think it was movement. I was kind of hoping it would be less sensitive to movement in the bracket, but I will try moving it some more.A dropoff like that would make me wonder if something moved slightly.
I did not find the bracket with the collimator worked any better, as a matter of fact, it was harder to work with than the pinhole.
Technically speaking, weight can be used for this. In a practical sense, load cells drift and this would be a challenging application for a home project. Even with a well-known commercial product intended to track keg contents (much larger delta), we have noted statistically significant drift.Would load sensors work for this since the weight is decreasing?
Check your "about" page (and make sure you do a shift+refresh to get the latest version):Super weird. It ended up working but I did not had the message saying it did.
