Nerf Security System

Using Amazon Echo for it's most desirable task; shooting roommates with nerf darts.

Usage

"Alexa, ask security to fire"

(Nerf dart fires)

echo: "Get wrecked"

Turret Setup

The turret is controlled through python using libusb and a flask webserver.

Install the python 2.7 dependencies:

$ pip install -r requirements.txt

Start the turret control + webserver

$ sudo ./main.py

You can test firing the turret through the webserver with a simple cURL request. The webserver defaults to port 5000.

$ curl http://localhost:5000/fire

For AWS Lambda function to communicate with the HTTP server you will have to setup port forwarding and make the port for the webserver accessible.

Alexa Skill Setup

You can find a tutorial for creating a Alex Skill and a AWS Lambda function here.

Lambda Function

Make sure you have npm installed first, then download the dependencies for the skill:

$ ./setup.sh

In the skill/index.js file update the PUBLIC_URL field to correspond with your webserver.

Create a zip upload for AWS Lambda function:

$ ./create.sh

Use the "skill.zip" to create and AWS Lambda function.
