My great-grandmother was deaf (since she was 10), and she knew if someone arrived after she went to bed (she was a farmer for much of her life, so she slept early).
How did she do it? Vibration. She could detect movement throughout the house. My great-uncle has a pretty good story of trying to sneak out/in after curfew.
So attach a motor connected to a smoke detector to the baseboard of a bed. For safety's sake, you'd use a pretty big motor. You'd also want to test it randomly.
- robalfonso 9y agoThey already make deaf alarm clocks for this. I actually use to use one for overnight alerts because I'm a heavy sleeper and I don't want to wake up my wife with my phone sounds.
- QAPereo 9y agoSame here, it has the ability to control the intensity and pitch of the tone, a unit to shake the bed, and the ability to flash a lamp of your choice. The lamp or the bed shaker is usually the way to go with someone else present, definitely.
- okreallywtf 9y agoThis was one of the things I liked about my fitbit, the vibrate alarm was more than enough for me since I'm a super light sleeper, and I can get woken up without waking up my gf. In fact, her fitbit vibrate would wake me up but not her but she's the one wearing it.

- rm_-rf_slash 9y agoI went to RIT; the constant BZZZRRRT BZZZRRRT BZZZRRRT of deaf alarm clocks going off in several dorms at all hours of the day just became a part of life.
