    i am a woodworker that enjoys electronics and magnetivity. i make custom woodworking lock boxes with hidden magnetic locks. what i'm trying to conceive is some type of heart rate monitor locking/unlocking device, or a blood pressure band.

    two things:
    1. if i got my hands on an electronic blood pressure cuff, in the box you have to put your arm inside the box while it's locked to actually reach the lock. when you insert your arm, the cuff automatically tightens, and this serves as a security feature for the lockbox. of course if you can't unlock the box, you're kinda screwed, until the timelock's timer countdowns, then the blood-pressure cuff releases and your arm is free again.

    2. if i had a heart rate monitor hooked up to a lock device, you would attach it to your arm, and actually have to get your heart rate on a specific number for a few seconds, sending a signal to a switch that unlocks the box. how can i accomplish either of these problems?

    thanks,
    David Dix
