USBrewMinder YouTube Video

YouTube Video #2 A bubble counter used to monitor fermentation progress making homemade wine. It could be used for making beer also. It minds my brew using a usb port. It continuously monitors alcohol percentage by counting carbon dioxide bubbles and then back-calculating the amount of alcohol produced. The concept is fairly simple; use an infrared LED emitter and detector pair placed on opposite sides of the fermentation lock. When a bubble passes by, it breaks the beam and sends an on/off pulse to teensy. On the PC side, a VB.net application to interrogates Teensy at a specified frequency and reports back the number of bubbles counted and converts volume of carbon dioxide produced to mass of ethanol produced. I also included a graph and a dashboard to track progress over time. Sandy Oates
