We Americans love upgrading to a new smart phone at every opportunity, and most of us have several of them stuffed in a drawer somewhere.
If you’re like me, you probably hate having a perfectly good portable computer (that’s really what a smart phone is) doing nothing more than gathering dust.
I’ve written several posts in the past explaining how to give an old smart phone a new life by turning it into something useful (like a wireless security camera), and I have another such tip for you today.
Believe it or not, by downloading a free app you can turn your old iPhone or Android phone into a fully functioning metal detector. In a nutshell, the metal detector apps instruct your phone to detect the magnetic fields of metal objects. I gave one of them a try with one of my old Samsung phones, and it works like a charm!
If you’re the industrious type, you can mount your new “smart phone metal detector” on the end of a stick so you can use it without bending over.
