Tech for Good Ten: A GPS system for the visually impaired, the surfers out to save our oceans and the latest $5 tiny Raspberry Pi

30th November 2015 Posted by: Cat Cochrane

Welcome to the Tech For Good Ten, where we share the best 10 links in the Tech For Good world from the past seven days.

We’re aiming to share a wide range of links, meeting the people behind the latest digital innovations, showcasing the greatest tech for good products, looking at the future of social change technology, and exploring the themes and social issues that technology is tackling locally and globally.

Most importantly, we’ll be meeting the people and institutions who are actually using this technology, showing the positive difference it makes in their lives, their communities and the world around them.

We’re also encouraging debate around “What exactly is Tech For Good?” Join the debate in the comments below. We’re here to discuss all things Tech For Good.
