Dream Hacker

Dream Hacker is program designed to help you have better dreams. Our projects monitors our users heart rate and plays an audio file chosen by the user. Once Dream Hacker detects the user has entered sleep ie. when the beats per minute is below a certain threshold it will play the selected audio.

This setup takes data from pulse sensor and time of the day etc, to predict when the person has slept. Then after a while start the audio stimulus.

About

Dream Hacker is program designed to help you have better dreams. Our projects monitors our users heart rate and plays an audio file chosen by the user. Once Dream Hacker detects the user has entered sleep ie. when the beats per minute is below a certain threshold it will play the selected audio.

Website interface enables user to select the music they want to play while they are sleeping. They can also see their different information using web Interface. The information will include bpm (beats per minute), the threshold and when the user has slept.

Roadmap

[-] Next Software Release (v2.0) - ML of sleep detection using Python and ML algo

• [-] User input integrated
• [-] User sleep timings integrated
• [-] Social Media Presence improvement
• [-] Pulse sensor improvements
• [-] Web-Server Improvments
• [-] Gather Training Dataset
• [-] Train sleep detection
• [-] Test on real samples

Getting Started

Installation

Hardware

• Set up the circuit as shown in the diagram.
• Put a speaker with it's audio jack in the audio output of the raspberry pi.
• For more information: Hardware Wiki

Software

1. Use SSH, VNC or a monitor and a keyboard to login to raspberry pi.
2. Install the audio player mpg123
3. Clone the repository somewhere in the Raspberry Pi.
4. Run the following commands from inside the repository 
 - cmake .
 - make

Usage

• Put your audio files inside the directory audio/.
• Edit the audio.txt file with the name of the audio you want to play when the sleep starts. For example if you want to play my_file.mp3 present in the audio/ directory then write audio/my_file.mp3. Make sure that the file has just one line.
• Run ./drmhk -h to explore what are the parameters which can be feeded as the input to the program.
• Example: If you want to run the program as a simulation and set the beats per minute threshold to 70 then run ./drmhk -s 1 -t 70.
• To run in default mode run ./drmhk

dreamhacker's Issues

Frontend Not resposnsive

Frontend is not responsive enough. Test are getting cut while resizing the browser.

Project Logo Creation

Software can play music both in c and Localhost

main.cpp should be able to play music in a thread. If the program is configured so. If not the localhost will play it.

Frontend change

Change frontend server from Apache to Nginx.

omxplayer is able to play music but webpage not

omxplayer is able to play music.

omxplayer is able to play music but webpages like localhost and youtube are not. That is no sound output from webpages.

ReadMe updation

Add How to use, contribution Insights, license etc different sections.

Localhost Requirements

The localhost must be able to receive the following values from main.cpp

Receive

1. Beats per minute value (Integer)
2. A variable which can take the following values "Audio On" or "Audio Off"

Send

1. The user must be able to set a threshold value of beats per minute on the webpage.
2. The localhost must respond to the main.cpp with the threshold value as a response.

User Interface Documentation

The Documentation needs to be completed soon. Please complete the user interface part of it.

Ppeline

Add pipeline from C++ to webserver

Doxygen Generation

Nginx config

Nginx config to serve realtime data with different php pages.

Use of CMake

Use Cmake to compile and run C++, refactor and add Inheritance from CPP timer class.

Web page can't play audio on Raspberry pi

Raspberry pi can't play audio, when it is played through the webpage on Shreyansh's Raspberry pi

Audio Selection

Audio selection using C++ and pi and synch with front end

Creation of client in c++

Creation of a client which will talk to the localhost.

Send

The client must be able to send the following values to localhost:

1. Beats per minute
2. A boolean signal "AudioOn" or "AudioOff"

Recieve

The client must receive an integer from the localhost indicating the threshold value of the BPM.

Add server creation/configs documents

Removing redundant code - C++

Music Not playing

In front end music is not playing

DyGraph merge with FrontEnd
