Well @anu you summed it all up nicely. So that’s how things look now. Pretty much a big puzzle 
Business-wise, my vision for this small coffee roastery is to be the world’s first fully open source and direct trade coffee business, for everyone to duplicate the model as easily as possible. Given that about 100 million people worldwide make their living from coffee farming right now, quite some impact is possible.
We’re not trying it all at once though. Right now @anu and I have worked on a few parts of the puzzle (and we’re inviting everyone interested to join or start work on a new part):
- open source optical coffee sorter, a project for our team in OpenVillage Academy
- an open source coffee production manual, started here, with 40 pages of more content I have written locally that has to be integrated; esp. covers DIY coffee import / export
- beginning of an open source coffee roaster, but not all at once; we’ll start from a simple commercial model to which we add open source electronic control, and later move to a complete open hardware product
Sometimes I still wonder how I got involved with coffee 
But then again, it still seems a low hanging fruit to improve livelihoods of small-scale farmers in Nepal, as they have the perfect conditions to grow a high-value crop. So why not combine it as the business model of an OpenVillage House. I hope to visit Nepal again in fall this year and help Anu get OpenVillage House Hetauda going. (And to enjoy another winter without snow.)
