Smallest Flash Light on Instructables.

I keep seeing claims of "smallest" flash light, so I thought I'd try and make my own, it took about an hour.

The LED is from an old cell phone key board, It would easily fit in a sugar cube, if I wanted to go smaller I guess I could use some hearing aid batteries but this was just stuff on hand.

I trimmed the led from the board with a band saw, then used wire cutters to cut off the unneeded circuit board. Then I soldered some thin wire from a solenoid Be sure to clean the coating off and pre-solder the wire end to make sure you'll get a good connection

Solder the top and bottom terminals and place the two cells in a bit of heat shrink tubing Come on every kid over 4 has made their own light it just isn't that hard I will say trying to solder connections smaller than a pin head is quite a test of patience. The cells were from a talking greeting card. Now you're done have fun it's brighter than you would think maybe your parts phone will have white light LEDs
