Introduction: Metal Detector

For my Electronics Lab, we were instructed to do a simple final project due at the end of the term. I searched some ideas and decided on doing this metal detector, its simple and cool.

Step 1: Tools and Supplies

Supplies Needed:

  • 9V Battery Clip
  • ne555
  • buzzer
  • copper wire
  • Two 10 micro-farad capacitors
  • 47k Resistor
  • Cardboard
  • Tape and glue

Tools Needed:

  • Wire Strippers
  • Pliers
  • Box Cutter

Step 2: Making Spool

  1. Strip the wire from its sheath
  2. Cut 2 equal size circles from cardboard
  3. Spool the wire and tape it, make sure to leave about 4 inches of wire from both ends to plug into your circuit
  4. Tape spool onto one carboard circle
  5. Place other circle on top

Step 3: Making Handle

  1. Cut out two identical peices of cardboard like so
  2. Size doesnt necessarily matter, more so preference
  3. Once having two peices cut out, glue together.

Note, depending on thickness of cardboard, more than two peices may be needed.

Step 4: Schematic

Step 5: Constructing Circuit

Step 6: Assembly
