I would like to build a sleep mask that unclasps itself at a pre-specified time, so that it is easier to fall asleep at night and wake up in the morning. I hope this is not the wrong place for this post.
Do you have any suggestions for how to proceed? I don't know how the clasp would work -- I suppose I could use an Arduino board to send a signal to an electromagnet telling it to switch off, although this seems like overkill for a timer and clasp, and I'm not sure I want an electromagnet near my head all night.
thanks, Sleep Deprived
