Doctor Who - Gadgets

I should probably tell you what Doctor Who is. He is an alien from Galifrey who travels through time and space.  He has fantastic gadgets. There is a sonic screwdriver ,that opens metal doors - but not wood.    A nano recorder which records sounds onto your hand.  His T.A.R.D.I.S (time and relative dimensions in space) is his spaceship/time machine.  His intellect is his best weapon. He uses it to outwit enemies and solve problems.
 There are twelve doctors, he regenerates instead of dying.  But more on that later.  
ALLONS-Y!!
