|

|
||||
## Hardware
|
||||
|
||||
* Raspberry Pi (Rev 2B)
|
||||
* Raspberry Pi
|
||||
* MAX 31855/6675 Cold-Junction K-Type Thermocouple
|
||||
* GPIO driven Solid-State-Relays/MOSFETs
|
||||
* GPIO driven Solid-State-Relay
|
||||
|
||||
## Installation
|
||||
|
||||
### Dependencies
|
||||
Download NOOBs and install raspian
|
||||
|
||||
We've tried to keep external dependencies to a minimum to make it easily
|
||||
deployable on any flavor of open-source operating system. If you deploy it
|
||||
successfully on any other OS, please update this:
|
||||
### Raspbian
|
||||
|
||||
#### Currently tested versions
|
||||
Download NOOBs. Copy files to an SD card. Install raspian on RPi using NOOBs.
|
||||
|
||||
* 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
|
||||
$ 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
|
||||
|
||||
#### Raspberry PI deployment
|
||||
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
|
||||
|
||||
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/apollo-ng/picoReflow.git
|
||||
$ cd picoReflow
|
||||
$ pip install Adafruit-MAX31855
