Dear all, sorry for my English. Today I want to show my homemade metal detector . Surf pi 1.2. I added a mini oscilloscope to view the eddy current . In this way easily I recognize the iron. Greetings to all dabbo1974.

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.

The funny thing is, I work hard to design projects that will tell me what is down there yet still dig every single target. Go figure.

Goodmorning everyone. Mini oscilloscope is DSO201. I connected the oscilloscope at the same points used to adjust the offset. it is very easy. Greetings

Posted on: October 12, 2015, 01:36:20 am
if you do not have an oscilloscope, you can build it with a smartphone Android.It is a very simple project. caution!!! voltage too high can damage smartphone.
