OK so v0.1 works, but I realise there's lots to do (I've starting raising these as Issues on https://github.com/terryspitz/train/issues):

1. Check for Timetabled trains as well as Arrivals (this is important at my local station Pinner since there is often only one train into London showing in Arrivals API).
2. Add a GUI for selecting WiFi and Password (nearly done)
3. Add a GUI for selecting Station and Line
4. Add support for Bus Stops
5. Support arrival time in mins vs. actual time
6. Add Station/Line Status check - very important!
7. Add sleep/wake times

I've also like to productionise the hardware: solder onto a stripboard or even learn how to design and order a PCB, add an on/off button, and build (3D print) a case.

Anyone think I could sell these on the web???
