At Domingo Club, we make fermented food, open-source tools and explore collaboration with natural processes to promote understanding, transparency, resilience and equity in our global food system.
We're developing an open-source fermentor that can be easily fabricated anywhere to promote fermented plant-based protein (tempeh) everywhere. An fermentor is a device that maintains the necessary parameters, such as temperature and humidity, for an environment suitable for the growth of mycelium (the vegetative part of fungi) and microorganisms of all kinds.
The main electronic components of the fermentor are: a Rapsberry Pico mounted on a custom electronic board, an OLED display and four buttons, a general toggle switch, a temperature and humidity sensor, a fan and two heating pads.
Notes on the current build of the Fermenter, ideas and improvements for the next version, what we like and what we dislike.
It is hard to finish one version without starting to think about the next.
We would like to simplify the fabrication process of the fermenter and therefore its design. By reducing the number of machines and materials needed to make it. We would like to explore a laser-cut model only so that it is easier for everyone to make their own.
Adding colours! We would like to add a protective, coloured finish to the wooden board. This will give the Domingo touch but more importantly protect it from moisture and bacteria colonies.
