[update 17 Mar 2017: Gordon has been working lately on changing and simplifying the installation process for openag_brain on GitHub. I haven’t been following the changes closely, but at some point, these instructions may become obsolete.]
Yesterday I got the PFC2 software stack running on a Raspberry Pi 3 and an Arduino Mega clone. I wrote up a detailed step-by-step procedure for how I did it as a gist on github. If you want to see screenshots of the PFC2 UI and the CouchDB administrative interface, scroll down to the bottom of the gist. In the “Review” and “Next steps” sections, I included links to the OpenAg documentation that I’ve found most helpful in the past few weeks.
Here’s the link to the gist: https ://gist.github.com/wsnook/24ea657cf600a3802b262a2798f8894b [edit Feb 17, 2018: I took this gist down a while ago because my old procedure is totally out of date. It stopped working due to changes in the code on github.]
I’m hoping this will be useful to other developers who would like to experiment with the OpenAg software without spending a lot of time and money on hardware. I spent less than $100 USD on the Pi 3 and Arduino. The hardware setup was quick and easy–power up the Pi 3 and plug in the Arduino.
