“In the last five to six years I began working with 3D printers and CNC machines. I started to build stuff, such as furniture and gadgets, and my first Raspberry Pi project was the Pi Snap Box. It’s the size of a mini-PC and is a box you put on the wall with one button on it. If you press the button, it takes three photos. It posts the first photo to a Facebook account for whoever the box belongs to. So for example, if you hang it up in a hairdresser’s salon and get your hair done all nicely, people could then see the good results on the hairdresser’s Facebook page.
