design a physical box

[samthiriot]

put some components far from each other:

• bluetooth far from the stepper engine (electromagnetic perturbations)
• RTC far from regulators and other heat emittors

[samthiriot]

keep ventilation in mind for heat emitters:

• regulators
• stepper engine
• ATMega chip

[samthiriot]

Design openings so the interesting LEDs can be viewed (but are still not intrusive)

Leave room to plug USB
