Raspberry Pi zero W on the go

I wanted a small computer that could be carried in my bag and that would provide USB master, WiFi, run Linux and I was fine with a headless setup.

The Raspberry Pi zero W has all those features for 10$. At that price it's easy to imagine using it for all kinds of other projects.

I paid more to get a complete starter kit with a wall charger, HDMI cable. It was worth it as it was so easy to get going.
