u9026a Posted May 21, 2017 Report Share Posted May 21, 2017 (edited) Couldn't find any reference in the manual about what "Ft" being shown in the droid window meant, but apparently it's a "Fermentation Test". Thought the thing had gone bad already. Clever thing this droid. EDIT - Found it, on page 9. Easy to miss though.

Pursya Posted May 21, 2017 Report Share Posted May 21, 2017 Brewart 101 is your friend. Most things are covered in the videos. Link to comment Share on other sites More sharing options...
Derren Green Posted May 29, 2017 Report Share Posted May 29, 2017 Does anyone know how the droid actually does this? There does not seem to be any sensors or the like inside the droid tub itself. How on earth does it detect propagation, fermentation, EOF etc? Am I asking too much here....is this wildly proprietary information? Just pure curiosity on my part.

Deeks Posted May 29, 2017 Report Share Posted May 29, 2017 It uses the temperature sensors to do the fermentation tests. There is an algorithm that BrewArt uses to test for fermentation which determines when it starts and finishes depending on the temperature change during the test.

I suspect that as the app can detect the temperature to 0.1 deg C, and the fact that the droid knows the ambient temperature, they are using an algorithm to check for exothermic <<-- big word there -- reactions caused by the yeast making alcohol and CO2. 1 1 Link to comment Share on other sites More sharing options...
Pursya Posted May 31, 2017 Report Share Posted May 31, 2017 Trying to insert a link but cannot. http://pericles.ipaustralia.gov.au/ols/auspat/pdfSource.do?fileQuery=Fr%7DuK%7D%84s%804twzs%7Co%7BsKOc%40%3E%3F%3E%40F%40%3FBGO%3F%40%3E%3F%40%3E%40%3EG%3C%7Ert4%82vsKp%80%7D%85%7C if youcopy and paste that text it may work 1 Link to comment Share on other sites More sharing options...
MattS Posted May 31, 2017 Report Share Posted May 31, 2017 Well found, but the link doesn't work ? as presented. However if you go to here and put "Fermentation Coopers" (without the quotes) into the search criteria, tick the box that says "include abstract text" and search you will be presented with some results. If you select the 4th in the list (for me) application no. 2008217539, click on the application number and select Specification/e-register then click on download specification(AU-A1) it will provide the PDF file describing the process. There is a second document (AU-B2) that seems to be an update to (AU-A1) but I only glanced at it. An interesting read. 1 Link to comment Share on other sites More sharing options...
Derren Green Posted May 31, 2017 Report Share Posted May 31, 2017 Wow Pursya/Matt, I can't believe you guys found that. You must have wayyyyy too much spare time. But I am glad you did. A very interesting read! Thanks for doing the research. 1 Link to comment Share on other sites More sharing options...

DrJones Posted June 9, 2020 Report Share Posted June 9, 2020 Just because I was curious and actually read it (thanks for posting the links): Brewart uses two metrics in order to detect if fermentation occurs or not: 1) As was mentioned before, it has a couple of very accurate temperature sensors. There are actually three as far as I know. One for the ambient temp, two inside with one at the bottom and one pretty far up. During fermentation, heat is generated and this can be detected. 2) The more interesting part is the second method that uses the two internet sensors to detect if a layering (temperature-wise) occurs or not. If there is fermentation, the bubbles rising up will disrupt the (natural) layering 'process' and an insufficient difference between the two sensors is detected - ongoing fermentation. As soon as this stops, layering is more stable and can be probed by heating/cooling and seeing if the layering is stable or not (that's why during the daily fermentation test you can observe heating/cooling). In addition to that they have some rules of thumbs like 'do assume end of fermentation only after X days have passed'. All that is described in the published patent so I don't feel that I would violate anything here, it just the explanation for the curious folks among us... 😃 3 1 Link to comment Share on other sites More sharing options...
J P Posted February 11, 2021 Report Share Posted February 11, 2021 that’s awesome. as you said not keen on prying proprietary information but generally knowing how the genius technology works in a general way is pretty awesome and makes me dig the unit even more. 1 1 Link to comment Share on other sites More sharing options...
AmericanAussie Posted February 4, 2022 Report Share Posted February 4, 2022 Has anyone tried an iSpindel in their BeerDroid? I want to keep an eye on my brews by electronically transmitting SG measurements. I'm concerned the readings might be inaccurate from ingredients sticking to it because we're not supposed to mix them by hand. Link to comment Share on other sites More sharing options...

I wouldn’t have thought so but it’s really nice to have a Tilt user confirm the Droid’s accuracy. Saving money home brewing is a well known fool’s fallacy but I figure by not having to purchase a fermentation fridge and a smart hydrometer I can almost justify my outlay on an expensive e-BIAB kettle.

Captain 3 Droids Posted February 5, 2022 Report Share Posted February 5, 2022 Personally I haven’t had an issue and the units outcomes speak for themselves. Perhaps the only time to consider one would be if continually bottling in glass. Dustin makes a point about costs and in the brew world items often stay on the shelf as the novelty wares off. 1 1 Link to comment Share on other sites More sharing options...

No significant benefit in spending that sort of money. A much cheaper option is the RAPT pill from Kegland but I don't think any of it is necessary.
