Sketch out a functional block diagram for your device. Be sure to include:
What functional blocks require power.
Inputs / outputs from the device.
How you will achieve the different light settings, including the blinking.
Sketch a physical design for your device, including:
Relevant approximate dimensions.
Mounting points for internal parts.
Access for battery.
Consider what aspects of the device need to be accessible to the user during operation.
The physical design sketches can be done by hand (paper-and-pencil drawings) or using CAD software (CAD software will ultimately be used, but can be slower when generating initial designs).
