To come up against an electric cable while drilling a hole in a wall can have catastrophic consequences. Likewise, drilling into gas, water pipes or central heating pipes can be extremely hazardous. With a handy metal detector it can now be determined beforehand whether there are metal objects to be found in a wall, ceiling or floor. An LED indicates if a metal object is in the vicinity.

Features

  • avoid disasters when drilling holes in walls
  • locate pipes, cables, metal studs, …
  • great project for novices
  • your own unique application
  • push button operation

Specifications

  • metal detecting distance adjustable: up to 8cm (3.15")
  • power supply: 9V battery (not incl.)
  • LED indication
  • 12VDC-buzzer connection (buzzer not included)
  • dimensions: 56 x 64mm (2.2" x 2.5")

Extras

  • Hints

    • If you experience difficulties with the calibration of the unit (ie if the LED doesn't turn off, when there isn't any metal present ), replace C1 with a ceramic 1.2nF (122) capacitor. This behaviour is due to a spread on the component values and differences created when winding the coils.
    • For those wanting an audible signal, space is provided on the print for connecting a buzzer type SV4/12-S. The small PCB has been specially designed to be incorporated into the separately available casing type G407.
