DeadmanPi

Server with a Deadman Switch!

Comment

DeadmanPi

Overview

This project was submitted to the HackDartmouth III event held on September 24 - 25, 2016.

The goal of this project is to use a Raspberry Pi 3 board along with GrovePi sensors to create a Node.js server that has a hard-ware DEADMAN switch. If certain physical triggers are detected by the Raspberry Pi then the sever will delete all of the files on the server. Originally, this project was meant to interface with the document sharing API at IntraLinks but this project still serves as a proof of concept of a server with a physical DEADMAN switch attached.

This project was built with Raspberry Pi 3, GrovePi Board, GrovePi Sensors, Node.js, Python, and Swagger.io.

Node.js powers the server as well as the RESTful API (which is powered by Swagger.io)

Python powers the DEADMAN switch.

Build Instructions

  1. Run

node server.js

  1. Run

(only once) git clone https://github.com/efeiefei/node-file-manager.git

cd node-file-manager

cd lib

npm install

  1. Run

cd deadman-pi

swagger project start

  1. Run

python deadman.py

http://localhost:10010 - RESTful API powered by Swagger.io

Setting Up the Pi

Everything currently runs on localhost.

Connect the GrovePi Piezo Vibration Sensor to AO on the GrovePi Board

Connect the GrovePi Light Sensor to A1 on the GrovePi Board

Connect the GrovePi Button to D3 on the GrovePi Board

Using the Pi

Make sure deadman.py is running.

Vibrating the GrovePi Piezo Vibration Sensor will trigger a DEADMAN

Covering the GrovePi Light Sensor will trigger a DEADMAN

Holding the GrovePi Button will trigger a RESET (button must be pressed for at least 0.5 seconds)

API Documentation

Run swagger project edit inside deadman-pi/

Using the API

curl http://localhost:10010/status; echo

"Online"

curl -H 'Content-Type: application/json' -X POST http://localhost:10010/kill; echo

"Killed"

curl http://localhost:10010/status; echo

"Offline"

curl -H 'Content-Type: application/json' -X POST http://localhost:10010/reset; echo

"Reset"
