Tutorial - Bubble Logger |
about 5 years ago
Aha, I misread the IR bit, (doh). Also @stephen, good idea on temp. A low-power micro with this gate, a thermistor, and some kind of RF transmitter (xbee?) == realtime brew monitor.
Cool idea though, I’m a homebrewer and this would be a cool way to measure yeast activity in some of my beers. Unfortunately I ferment in a dark area (I use glass fermenters and the hops compounds break down unpleasantly in UV or even visible light – “skunking”) so I’d need to use some kind of dim ambient light for the photo gate to pick up the change with the bubble. An LED, maybe.
If anyone reading this is interested in getting into brewing, the best place to start is: “How to Brew” http://www.howtobrew.com/intro.html – it’s about brewing beer at home, but most of the same techniques and equipment apply to wine.
Did you sanitize everything? (water, sugar, and all the equipment that came in contact with your wine?)
If not, your wine most likely got wild yeast or bacterial infection from unsanitary equipment or from the sugar or even from tap water. Nasty microbes are everywhere and love to eat sugar-water. Only certain microbes actually make something that tastes good.
You could make some decent tasting wine this way (see http://www.homebrewtalk.com/f79/welchs-grape-juice-wine-21093) if you sanitized your equipment. Immersion in solution of water and iodophor or star san [mostly phosphoric acid] or even bleach would do it. Also you’d want to boil at least the sugar (in a sugar-water solution) and the water. 15 minutes should do it. (for the water, you can just use sterile water like store-bought spring water, but the sugar needs to be dissolved and boiled)
Of course, if the point was just fermenting something to bubble for the experiment that you didn’t intend to drink, mission accomplished. :) Of course, you could have just used sugar-water and bread yeast for that.
No public wish lists :(
