I've been messing about with gadget mode on the Pi, and finally got it working. It has some exciting possibilities. So, I built a project page for it so I don't forget how to set it up. And, while I was working on it, I needed to get WiFi going without a windowing environment. So, I built a project page for that too.
What's Gadget mode? It lets the Pi act as a USB device. Memory, network and serial devices are supported. I think the most exciting ability is network: it means you can network two Zeros with only a USB cable. How cool is that? I plan to use this capability when I do maintenance on my many embedded Zero projects. And I'll probably use it to occasionally add a second screen to my main computer, a Pi 2. I know it'll work because I did the same thing many years ago on a PC, using an all-in-one PC as the second screen.
