Kiln Controller
|
|
==========
|
|
|
|
Turns a Raspberry Pi into a cheap, web-enabled kiln controller.
|
|
|
|
## Features
|
|
|
|
* easy to install and run on most Raspberry Pi versions
|
|
* easy to create new kiln schedules and edit / modify existing schedules
|
|
* no limit to runtime - fire for days if you want
|
|
* view status from multiple devices at once - computer, tablet etc
|
|
* firing cost estimate
|
|
* NIST-linearized conversion for accurate K type thermocouple readings
|
|
* supports PID parameters you tune to your kiln
|
|

## Installation
|
|
|
|
### Raspbian
|
|
|
|
Download [NOOBs](https://www.raspberrypi.org/downloads/noobs/). Copy files to an SD card. Install raspian on RPi using NOOBs.
|
|
|
|
$ sudo apt-get install python-pip python-dev libevent-dev python-virtualenv
|
|
$ git clone https://github.com/jbruce12000/kiln-controller.git
|
|
$ cd kiln-controller
|
|
$ virtualenv venv
|
|
$ source venv/bin/activate
|
|
$ pip install greenlet bottle gevent gevent-websocket
|
|
|
|
Note: the above steps work on ubuntu if you prefer
|
|
|
|
### Raspberry PI deployment
|
|
|
|
If you want to deploy the code on a PI for production:
|
|
|
|
$ cd kiln-controller
|
|
$ virtualenv venv
|
|
$ source venv/bin/activate
|
|
$ pip install RPi.GPIO
|
|
|
|
If you also want to use the in-kernel SPI drivers with a MAX31855 sensor:
|
|
|
|
$ pip install Adafruit-MAX31855
|
|
|
|
## 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
|
|
|
|
## Usage
|
|
|
|
### Server Startup
|
|
|
|
$ source venv/bin/activate; ./kiln-controller.py
|
|
|
|
### Autostart Server onBoot
|
|
If you want the server to autostart on boot, run the following commands
|
|
|
|
$ /home/pi/kiln-controller/start-on-boot
|
|
|
|
### 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).
|
|
|
|
### Simulation
|
|
|
|
Select a profile and click Start. If you do not have a raspberry pi connected
|
|
and configured, or if you don't install the Adafruit-MAX31855 library, then
|
|
your run will be simulated. Simulations run at near real time and kiln
|
|
characteristics are defined in config.py.
