Benjamin Blundell has been working on his DIY smart-watch:
I have an issue with smart-watches. Watches in general fall into one of two categories: a tool to tell the time, or a fashion statement. Increasingly, I believe the latter category is larger than the first. With the advent of the iWatch, Pebble and the like, fashion and making a statement has moved into technology. It’s not quite a new thing but nevertheless, it’s something I’m not too fond of. My solution? Make your own smartwatch.
There is a precedent for this. Steve Wozniack sports a pretty fly nixie tube watch which he made himself. It’s pretty cool, but also a statement of sorts too. I’ve been meaning to up my game with electronics anyway, so I’ve been working on a few initial prototypes.
