A cool alarm clock project from Instructables user derwassi.
I often have the problem, that I have trouble getting up in the morning, while at the same time, I have trouble falling asleep in the night.
I’ve checked out several possibilities to make both easier…
I decided to build my own device.
Despite the title I won’t call it an alarm clock, but a sleep supporter. It should not be there to wake you up, but give you a better sleeping experience (i.e. fall asleep faster, and get up easier).
I wanted to have a sleeping cycle alarm combined with a sunrise alarm: by detecting your movements during night, your next light sleeping phases will be detected, and the light alarm will be scheduled accordingly (it must start prior to your upcoming light sleeping phase, so some estimation must be done here). The movement detection should be unnoticable (no wristbands or whatsoever).
The same concept of movement detection can also be applied in an ebook reader / ambient sound player: volume is turned down after a few minutes, when no motion is detected within a certain time frame the audiobook stops playing. The position when you moved the last time to continue playing is stored, so the book can be played from this position.
As my night stand is not that big and the sleep supporter emits light anyway, It can be used as a lamp or moodlight.
It should not display time or anything. In my opinion displaying time would lead to pressure and pressure leads to bad sleep.
