Introduction: How to Make Empty Wallet Cash Indicator

About: My name is marjancho and I love electronics,makeing gadgets,hack and pranks.

For makeing this led indicator for your wallet you will need one CR2016 lithium battery,one small magnet and led diode.
How it works,when there is no money in wallet the led is on and mean to put cash in wallet,when cash is inside wallet the led is off,circuit is very simple but great :)
