Domingo Fermenter
Fabrication
Cabinet design
The fermenter has been designed and manufactured using digital fabrication techniques which are CNC milling, laser cutting and 3D printing. The design is harmonious, unique, compact and clear with particular attention paid to the choice of materials for a sustainable product. The external enclosure is made of natural wood fibre panel dyed in the mass with organic colouring agent, very satisfying to mill with great finish and texture. The shelves and the inner technical panel are lasercut from aluminium sheet for easy maintenance, durability and heat transfert. Fastening systems are complemented by 3D printed parts made of PLA, a compostable polymer obtained from corn starch.
Soldering tips and tricks
We find it easiest to start soldering the small components on the back side (where the Domingo logo is) so you can keep the PCB flat on your work surface.
The diode has a direction and therefore a line painted on its packaging. It indicates the ground. It goes to the side of the longest line seen on the PCB.
The Grove connectors have legs on both sides that must be soldered as well to strengthen the components in place. Especially because they will receive forces when connecting and disconnecting cables.
The direction of the Raspberry Pico can be seen from the small rectangle on the PCB indicating the Pico’s USB port. Solder it accordingly.
