Here is a simple coil for your metal detector.
Things you to need to make the coil.
Coils specs
coil diameter 11.5cm
wire diameter 0.5mm
coil turns 45
core -3 dvds glued together with hot glue
Where to get magnet wire.
safety first
You can buy magnet wire off the internet but plenty can be found in a CRT TV or monitor also.This envolves high risk of electrocution though.If you don't know what you are doing don't try this.Read the DANGER OF ELECTROCUTION section first.
Magnet wire is hidden in the degaussing coil wrapped around with electrical tape.
DANGER OF ELECTROCUTION!
There is danger of electric shock involved when opening up a TV. It's capacitors and other component can hold the electrical current off-grid for a long time.In some cases for months!You need to discharge the TV first before touching anything.IF YOU DO NOT KNOW WHAT YOU ARE DOING DON'T TRY THIS. JUST BY MAGNET WIRE OFF THE NET.
How to make the coil.
Glue ,say, three dvds together with silicon glue.
Wrapp around the dvds with magnet wire,say for example,45 turns.
Glue the wire.
That's it.
