Well, about the metal detecion, ive some small metal detectors. the
shape of them is a threaded cylinder they vary from about 1cm in
diameter to 0.5 cm. The range in length from 4-6cm. Im not exactly sure
how they work, but i know how to use them. They have three leads, +,
ground and switch. The problem is they take 18v. Im not sure if they'll
work on 9 but i think they will. I got them from a friend, there from
the process control business, i think they are about $50 each. I could
be wrong though. Im just not sure how they're hooked up. They're made
by balmer electric. Hope this helps.

| (...) These are standard inductive proximity switches. They have a small amount of electronics inside, and generate an oscillating magentic field. Bringing any piece of conductive material close, alters the behaviour of this field. Different types (...) (25 years ago, 14-Jan-00, to lugnet.robotics)

| I was musing over what the well sensored robot would be sensing next and it crossed my mind that a small metal detector sensor might be an interesting addition. Light sensor electrical interface. Brick sized. Limited range but could provide (...) (25 years ago, 13-Jan-00, to lugnet.robotics)
