	Building a pinpointer as my 1st md « on: January 12, 2013, 09:14:24 pm »

Hello, I'm a beginner and don't have a md yet. I wonder how does a pinpointer works and can someone teach me how to make it? Embarrassed

Edit: I don't have electronic backgrounds and i don't know how is a pcb made. Can someone tell me?

Little Cow!

Pin pointers come in all types.

All they are is a Metal Detector with Limited depth and abilities.

They make them as simple TR Transmit Receive, IB Induction Balance, PI Pulse Induction and Even the Good Ol BFO Beat Frequency Oscillator.

Never Seen one built like a VLF as you don't need Discrimination on them. LOL

If your Handy and know a bit about Electronics you can build one with not so much problems.

You can buy Metal detector kits from places like Jayco that make Ok Pin Pointers.

Take a Look in here.

Oh, dear. You are in for a lot of work. This isn't like building a model airplane or model car, mate. This is seriously hard stuff you are asking about.

Don't let that stop you. Just be ready for it.

It's all about that moment when metal that hasn't seen the light of day for generations frees itself from the soil and presents itself to me.

What about building a metal detector (not pinpointer), where can i find the schematics. Just need a basic one which can work like teroso compadre. Can't buy it cause the shipping is too expensive.

I've bought two project boards from Silverdog and both worked fine. In fact, Xavier has one of the boards.
