Yes, you need to wake up every morning. Why not wake up to the time being projected on your roof or wall. That way you know how late you are when you sleep in.
"Designed by the world reknown Stefano Giovannoni, this wireless projection clock is the first of its kind. The projection unit can be moved positioned in any way you like to give you the best possible view of the time. This self-setting clock also features dual alarms, indoor temperature, and contactless keys." - Oregon Scientific
