Tobben Log
I'm studying RepRap workshops, events where participants build their own generally useful production machines that can produce a large fraction of their own parts.
I want to find factors that predict whether participants become workshop organizers themselves or not.
This would let us design workshops that reproduce and evolve while simultaneously distributing the machines' potential to improve people's standards of living and quality of life on a large scale.

Meeting with Jonathan and Marcin.
- We should investigate bulk prices for key parts (like stepper motors)
- I (Tobben) should collect some stories from the people I've given printers to. Stories of people who got empowered and made some money with their new RepRap knowledge and machines.
- Thesis data collection nr 1 happens tomorrow when Folgertech Prusa i3 kit is assembled on the Factor e farm.
