Easy to manufacture and assemble 

Must be able to safely store and pack all electronics

Current draw must be less than 200 mA to accommodate use of an Arduino Uno

Must allow for 5 different forms of mechanical input

Calculated the current draw of all collective components to ensure that the Arduino Uno could accommodate all the electronic features (<200mA)

Designed the cube for assembly, used threaded slots on 5 edges of the cube so that it could be easily assembled/disassembled, tapped holes for rotary encoders, potentiometers, and analog switches.

Developed and submitted a functional electro-mechanical system within 36 hours that is linked to a web-application

Utilized Firebase as a central database to pass information from the cube to the web-application as a JSON package where it was then parsed and graphed to outline potential trends

Was successful in thoughtfully developing CAD, SLS-3D printing parts, wiring electronics, developing code, and integrating the electro-mechanical system within a short-time span.
