This is one of the smallest flashlight that you can make.
you dont need special tools, casing,switch,etc.
its simple and quick project that you can make just following this steps :D
Step 1: Parts
You will need :
1x LED ( any color,white is brightest)
1x cr2032 battery ( 3v battery, button cell)
some glue from glue gun
Step 2: Building
First you gonna do is to cut small peace of glue.
than put anode of LED to positive side of battery. Put peace of glue on anode and start heat it with lighter ( for 2-3 s) . when you melted glue just ake scalpel and push it so that glue can stick to battery.
