A combination of Internet of Things and 3D printing, A Product Design project in London, United Kingdom by Benjamin Redford (VIDEO)
Make your own Olly.
You can make the first version of Olly yourself using a 3D printer and off the shelf parts. This was the first prototype we made (under a creative commons license) and it’s slightly bigger. You can find everything you need here, and buy all the components you need from the shops (it’ll be a bit more expensive though)!
