Design/Functional Requirements

Output

Hardware

• pair of 1W white LEDs (attached inside sunglasses)
• driver for stereo headphones (speakers TBD)

Software

• low-frequency flashing of the LEDs
• pink & white noise generation

(adjustable, see modes below)

User Interface

Hardware

• two rotary encoders (with pushswitches)
• tiny OLED display

Software

The hardware controls/display allow the navigation of the following modes for adjusting settings:

Light Modes

• Brightness (overall, 0-100%)
• Frequency (1-50Hz)
• Light Phase (between left/right LEDs, 0-360°)
• Light Balance (level offset, -50...50)
• Light Wave (sine/square)

Sound Modes

• Volume (overall, 0-100%)
• Audio Balance (level offset between left/right, -50...50)
• Audio Phase (between left/right channel, 0-360°)
• Sound Wave (white/pink noise)

safety :

• always start with LEDs off when switched on
• push switch to immediately switch LEDs off
• timer controlling active period - initially say 1 min (epilepsy)
