The trick for alarm clock manufacturers, then: to craft devices that wake you, but just enough — an impossible calibration across the craggy depths of individual slumber. The “Vibrating Alarm Clock” by Karlsson is meant to slip under your pillow and then vibrates, its keys encased in a plastic sheath to prevent accidental midnight deactivation*. It doubles as an LED flashlight. In the morning, put it in its recharging station, where it reclines the rest of the day as a simple clock.
If you don’t have a phone — or you use a Windows Mobile handset that would snap your neck if you secreted it under your pillow — you can pick up Karlsson model for just £25.
