I gave a talk at the open source hardware user group recently titled “The Needs of Others”. It was half outlining what is known about the effective delivery of technology aimed alleviating technology and half talking about how faithful reproduction of physical objects at any reasonable scale is dependent good documentation and then exploring the challenges all int he context of Free and Open technology. Unfortunately I only had 20 minutes while it was at least an hours worth of talking.
I really enjoyed it and the other two talks we great.
It was the first time I had to talk about the topic so the practice was great and I now have a better feel for it. Might ask a few ewb branches if they need a speaker
