The art of Brewing Beer has apparently been around in various form for thousands of years. Fortunately we do not need the blessings of knowing a heap of history to appreciate a good ale or lager. These 3-D parts are designed to help people enjoy brewing and possibly take it to the next level. There are three main components.
**Sugar Dispenser**
The first part is a calibrated sugar priming system combining a sliding plunger and a body with a PET bottle as a sugar reservoir. Pulling the plunger back and forwards delivers a known quantity of sugar to prime every bottle (in this case a 375ml, a "stubby" in Australian terms). 60-70 bottles can be primed very quickly and conveniently and with increased accuracy over using a teaspoon! Changing the diameter of the delivery holes will alter the quantity of sugar delivered. If the smaller style beer bottle is used it may over carbonate, you may need to experiment here, or just enjoy a full frothy head anyway!!!
**Computer Monitoring**
The second part is an ESP32 computer project that has two temperature sensors, a solid state AC switch to control the temperature, and it also counts the bubbles in the CO2 fermentation lock. The Aidafruit Feather has been used and it provides enough capacity to convey brewing feedback via a webserver on a local wi-fi network. The web server reveals the brewing temperature the thermostat is set at, the external temperature around the brew box, the duty cycle of the heater (how hard is it working?),…
