planning a project!

Can anyone suggest me,from where should i start from as am trying to prepare a setup to detect alpha rays level in your body and instantly turn off ur system or ipod or television..

The idea occured to me when i want to listen to music,watch television until i fell asleep!

Coz I are a terrible Engrishman ! (actually I'm Welsh but don't tell anyone)

Seriously, I think we need a new section on Edaboard for people who can only send messages 160 characters long and can only type with one thumb.

Mr.brain i have corrected my text.... now decide whether these people really need to keep another edaboard or not...

Is there any sensor to detect alpha rays?

It is only possible if you can detect the level of alpha rays.

Thank you for editing your original message Pbeie, it is much easier to read now and we can understand the question clearly.

Yes, you could do it but as far as I know the only way to detect "alpha rhytms" (Alpha rays are something completely different) is by direct electrical contact to the head. Nothing is radiated, they can only be detected by measuring tiny potential differences on the skin around the skull.

Although not impossible, I would think your idea is impractical for safety reasons. Detecting sleep with wire electrodes attached to your head sounds like a recipe for hanging yourself in bed.

I'm sure I don't deserve it. All this praise goes to my haed.
