To begin, a preliminary Needs Assessment was delineated:

Needs Assessment:

Design Quality

• Build housing that fits needs and is custom for this purpose
• Simplify wiring and connects
• Easy reparability
• Aesthetically pleasing
• Takes as little space as possible
• Physically possible

Next, the layout of the housing box was precisely measured for creation via 3D modeling. This modeling is still in the works.

Then, brainstorming began on how the inside of the box would take shape. Given the space, there will be two levels. The top level will be the power supply that is supported via a 3D-printed shelf. The level underneath this power supply will house the EZ Drivers, which send information to the pumps and are controlled via Arduinos. The leftover space will house the Arduinos and the Raspberry Pie controller (this controls all the Arduinos).

All supports and casings for the equipment will be 3D-printed.

We are in the process of brainstorming the best way to organize the wires within the housing box. We need a 3D-printer EZ Driver structure to:

• Take wires up and away from boards without excessive bending
• Provide path to holes on outside of structure
• Provide path for cooling tubes through center of the driver housing
• Provide structural support to the central driver housing
  • Connect vertically through holes to central driver housing
  • Should fit modular central driver housing and outer wire housing

The next step will be redesigning the Central Driver Housing, specifically creating: 

• Holes for water cooling in median between drivers
  • Holes are alternating for each driver
• Holes to connect the EZ Driver structure
• Two long pieces that each have 12 EZ drivers, 6 on each side
• Output holes
