Kiln-Controller
==========

Turns a Raspberry Pi into a cheap, universal & web-enabled kiln controller.
Of course, since it is basically just a robot sensing temperature and controlling
environmental agitators (heating/cooling) you can use it as inspiration / basis
when you're in need of a PID based temperature controller for your project.
Don't forget to share and drop a link, when you do :)

## Hardware

  * Raspberry Pi (Rev 2B)
  * MAX 31855/6675 Cold-Junction K-Type Thermocouple
  * GPIO driven Solid-State-Relays/MOSFETs

## Installation

#### Ubuntu/Raspbian libraries

    $ sudo apt-get install python-pip python-dev libevent-dev python-virtualenv

### Quick Start for all linux environments

    $ git clone https://github.com/jbruce12000/kiln-controller.git 
    $ cd kiln-controller
    $ virtualenv venv
    $ source venv/bin/activate
    $ pip install --upgrade setuptools
    $ pip install -r requirements.txt
    $ ./kiln-controller.py

## Configuration

All parameters are defined in config.py, just copy the example and review/change to your mind's content.

    $ cp config.py.EXAMPLE config.py


### Autostart Server onBoot
If you want the server to autostart on boot, run the following commands

    sudo cp /home/pi/picoReflow/lib/init/reflow /etc/init.d/
    sudo chmod +x /etc/init.d/reflow
    sudo update-rc.d reflow defaults

### Client Access

Open Browser and goto http://127.0.0.1:8080 (for local development) or the IP
of your PI and the port defined in config.py (default 8080).
