Ported to Beaglebone (Kernel 4.1+)

• install "cape-bone-reflow" from https://github.com/robert-budde/bb.org-overlays
• add "cape_enable=bone_capemgr.enable_partno=cape-bone-reflow" to /boot/uEnv.txt
• sudo cp systemd/picoReflow.service /etc/systemd/system/.
• sudo systemctl enable picoReflow.service
• sudo systemctl start picoReflow.service

Turns a Raspberry Pi into a cheap, universal & web-enabled Reflow Oven 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 :)

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

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:

• greenlet-0.4.2
• bottle-0.12.4
• gevent-1.0
• gevent-websocket-0.9.3

$ sudo apt-get install python-pip python-dev libevent-dev
$ sudo pip install ez-setup
$ sudo pip install greenlet bottle gevent gevent-websocket

$ emerge -av dev-libs/libevent dev-python/pip
$ pip install ez-setup
$ pip install greenlet bottle gevent gevent-websocket

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.

$ git clone https://github.com/apollo-ng/picoReflow.git
$ cd picoReflow

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

$ ./picoReflowd.py

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).
