[sci.electronics] Nifty Door Handle Alarm.

Howdy Netland,

	I was at the local flea-market today and I bought this little touch
sensitive door handle alarm. What you do is just hang the unit on the inside
of the door handle and when someone grabs the handle the alarm goes off, it
even goes off when your a few inches away form the handle. My question to you
is this; the unit will only work on a non-metalic door with a metalic handle
what can I do to modify it to work on a metalic door? I know this is a very
vague question but unfortunatly I have no other Information execpt that the
unit uses a 4069 CMOS Hex-Inverter.
 

					  Thanks For Any Help.
