kilnController
|
||
==============
|
||
|
||
Turns a Raspberry Pi into a cheap, universal & web-enabled kiln Controller.
|
||
Forked from the reflow oven project: [picoReflow](https://apollo.open-resource.org/mission:resources:picoreflow) which I found through a blog post on [succulent ceramics](http://succulentceramics.com/2016/10/07/wifiraspberry-kiln-controller/)
|
||
|
||
I used kilnController to add a firing schedule control to a little pottery kiln I picked up second hand. The kiln is 10A/240V rated to 1000 degrees C. It has a door switch and a basic thermostat which allows for 25%, 50%, 75% or 100% power but no timer, which means constant monitoring if you want to ramp the temperature up slowly or soak the wares at any point. With the kilnController I can now set it up for a bisque or low temperature glaze firing and leave it to its own devices, checking progress every now and then on my mobile phone or PC.

## Hardware
|
||
|
||
* [Raspberry Pi Zero W](https://raspberry.piaustralia.com.au/raspberry-pi-zero-w) - any pi will do but the zeros are the cheapest at about $15 here in Australia
|
||
* [MAX 31855](https://www.adafruit.com/product/269) Cold-Junction K-Type Thermocouple (about $6 on eBay)
|
||
* [K-Type Thermocouple Sensor](https://www.google.com/search?q=K-Type+Thermocouple+Sensor+1250+1M+SY+site%3Aebay.com.au) -100°C to 1250°C ($3 on eBay)
|
||
* Solid State Relay Module [SSR-25DA](https://www.google.com/search?q=Solid+State+Relay+Module+SSR-25DA+25A+%2F250V+3-32V+DC+Input+24-380VAC+Output+pOK) 25A /250V 3-32V DC Input 24-380VAC Output (again, about $6 on eBay)
|

|
||
### Wiring
|
||
MAX31855 to RPi PIN (Pin Name)
|
||
|
||
Vin not connected
|
||
3Vo to Pin 1 (3.3v DC)
|
||
GND to Pin 9 (Ground)
|
||
DO to Pin 11 (GPIO 17)
|
||
CS to Pin 13 (GPIO 27)
|
||
CLK to Pin 15 (GPIO 22)
|
||
|
||
## Installation
|
||
|
||
### Dependencies
|
||
|
||
External dependencies have been kept to a minimum to make it easily
|
||
deployable on any flavor of open-source operating system.
|
||
|
||
#### Currently tested versions
|
||
|
||
* greenlet-0.4.2
|
||
* bottle-0.12.4
|
||
* gevent-1.0
|
||
* gevent-websocket-0.9.3
|
||
|
||
#### Ubuntu/Raspbian
|
||
|
||
$ sudo apt-get install python-pip python-dev libevent-dev
|
||
$ sudo pip install ez-setup
|
||
$ sudo pip install greenlet bottle gevent gevent-websocket
|
||
|
||
#### Gentoo
|
||
|
||
$ emerge -av dev-libs/libevent dev-python/pip
|
||
$ pip install ez-setup
|
||
$ pip install greenlet bottle gevent gevent-websocket
|
||
|
||
#### Raspberry PI deployment
|
||
|
||
If you want to deploy the code on a PI for production:
|
||
|
||
$ pip install RPi.GPIO
|
||
|
||
This **only applies to non-Raspbian installations**, since Raspbian ships
|
||
RPi.GPIO with the default installation.
|
||
|
||
If you also want to use the in-kernel SPI drivers with a MAX31855 sensor:
|
||
|
||
$ sudo pip install Adafruit-MAX31855
|
||
|
||
### Clone repo
|
||
|
||
$ git clone https://github.com/botheredbybees/kilnController.git
|
||
$ cd kilnController
|
||
|
||
## Configuration
|
||
|
||
All parameters are defined in config.py. There's a copy in config.py.EXAMPLE so you can review and change things to your heart's content.
|
||
|
||
## Usage
|
||
|
||
### Server Startup
|
||
|
||
$ cd kilnController
|
||
$ python kilncontrollerd.py
|
||
|
||
### Autostart Server onBoot
|
||
If you want the server to autostart on boot, run:
|
||
|
||
sudo nano /etc/rc.local
|
||
|
||
add the line:
|
||
|
||
`sudo python /home/pi/kilnController/kilncontrollerd.py &`
|
||
|
||
### 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 8081).
|
||
|
||
