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
I have a 9.6v battery and want to make a detonator but don't know what resistors to use for the LEDs?
Howe much do u need to make a wire glow to set off fireworks?
i dont know. but here is full list of nice projects for firework igniter <br> <br>https://www.instructables.com/tag/type-id/?sort=none&amp;q=FIREWORK+IGNITER
you will need 2 aa batterys because resistance of 50ft 12 gauge wire is only 0.08 ohms
How many AA battery's do u need to power through 50 ft of wire
How do I hook a LED up to a 9 v battery with out burning it out?
you need 330 ohm resistor to connect on + end of battery <br> <br>this is calculator http://led.linear1.org/1led.wiz
I Reilly like it
Sorry to bust yer bubble but the led's that back light cell phones are smaller than a pin head, the only problem is hooking them up without breathing because a puff of air blows them away. <br/>A hearing aid battery and an led would fit easily in half a sugar cube
oh man, i said its one of the smallest flashlights not the smallest flashlight. <br>Also i could trim anode and cathode and use smaller battery, and instead of 5mm LEd i could use 3mm led .......you could make smaller then this but not easy as i did.....thank you for comment
Please submit a new twist for this as all this is, is an led throwie, which has already been shown here.
it isnt LED throwie. led throwie is LED atached to battery and its turned on all the time... <br>my instructable is about LED whose anode is attached to baterry and cathode is free, so when you push cathode to battery (negative end of battery) it turns on.
