Affordable, accurate communication through blinking for people with conditions that don't let them otherwise.

Hardware Setup

You'll need an Arduino, 1 megaohm resistor, and some leads. Wire the resistor between 2 and three, and add the lead to the foil on the pin 3 end.

Mount the headset on a baseball cap so it is right next to your eyesocket. Make sure it isn't touching, only when you blink.

Software Setup

1. Install the server dependencies: cd backend, pip3 install -r requirements.txt
2. Install the frontend dependencies: cd frontend, npm i

Usage

1. Run the server: cd backend, python3 server.py
2. Run the frontend: cd frontend, npm run dev

Sequences

Blink uses a slightly modified version of Morse code. All letters are the same, but to advance to the next word, wait around 2 seconds, and to add a space, do ....-.

Special sequences:

• To start running: ..--
• To stop running: ......
• Space: ....-
• /: ---...
• Backspace: .---.
• GIPHY: ---... --. ....-
