With the light switch obtained from B&Q and the Nanode obtained, pre-assembled, from the States. I set to work coding the basic method of communicating with the switch.

As winter drew in, the days got shorter and waking up in the morning became even more of a chore than usual. We'd looked at getting a SAD light in the past, to make winter morning wakeups that bit easier but knowing how they work and the massivley inflated prices they were available for, I refused to buy one on principle.

My mind turned to home automation. Specifically, turning the bedroom light into a giant SAD light.
