TED: Vinay Venkatraman: “Technology crafts” for the digitally underserved - Vinay Venkatraman (2012)

Summary: Two-thirds of the world may not have access to the latest smartphone, but local electronic shops are adept at fixing older tech using low-cost parts. Vinay Venkatraman explains his work in "technology crafts," through which a mobile phone, a lunchbox and a flashlight can become a digital projector for a village school, or an alarm clock and a mouse can be melded into a medical device for local triage.
