 radio turns off when you do.

My radio has a handy feature which let's you say 'turn off in half an hour' (you press a button to say it). I like that, it's quite handy, but what tends to happen is either I'm still awake when it turns off or, I forget to set it and then am woken at 4am.

I therefore propose a slight modification which uses something like passive infra-red to work out whether you're still awake (moving) and plays music whilst you are. If it turns off because you're too still, a simple hand clap will turn it on again.

       What about tossing in your sleep? Would that cause Puccini? Or would you still have silence? ie, does it eventually stop sensing motion/noise?

       three very good alternatives [k_sra], but I'm not persuaded away from my Radio 4

       Helpful idea. I used to leave my radio on at a low volume all night long, and strangely enough all of my dreams had music in them. Kind of like a bad movie.

       If you're a restless sleeper, how would this be helpful at all? Get a Bose - keep the remote near your head, hit the top middle button to snooze. Requires little effort, easy to get back to sleep.

       I read about some scientists studying sleep who used a very simple method. They put a device on your wrist that can tell when its moved. Apparently this works well, as people generally keep moving, even if only slightly, until they fall asleep. I'll try and find a link.
