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 :)

Standard Interface

Curve Editor

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).
