Install it

It's on the app store as "Sam's Clock". Or,

Install from your laptop

You need mpremote, then:

make mkdir
make push connect

Wait while it pushes the code to the badge, then ctrl-d, the badge will reboot and you should see a new app called Clock.

Note: the badge must be connected to some sort of Wifi when the app starts-up so it can do ntptime.settime(). Without this it crashes hard.
