News: Hack a metal detector from a calculator

Hack a metal detector from a calculator

Our good friend Kipkay is at it again! He has earned six figures from videos like HowTo Unlock Handcuffs and HowTo Make a Stink Pen

Here he teams up with Howcast to deliver the ultimate treasure hunter's secret weapon: a metal detector. This homebrew hack combines the AM frequency receiver of a radio with the wave emission of the calculator. When you move the calculator close to metal the frequency intensifies and a beeping noise is emitted from the radio. This hack is super basic and fun even if you're not hunting for gold!
