This is my entry for the flashlight contest.
In this instructable I will be showing how to make a rechargeable flashlight that charges from your car. I got this idea as I often find myself using the flashlight that I keep in my car, but have come to it many of times with a dead battery. So my idea for a rechargeable flashlight started. It is fairly simple device, it is a flashlight after all. I did need to order one part from the internet. The light output of this flashlight is quite usable and probably perfect for being used around a car. With that said let's get started making the flashlight.

Just a quick breakdown of things I used in the process of making my light.
Parts:
3 white leds
5 10 ohm resistors
small switch ( I used RS # 275-0645)
li-ion or li-poly battery (single cell) (mine is only 70mAh)
li-ion/li-poly charger single cell ( I got mine from adafruit here, sparkfun also makes one)
USB mini B connector (cut mine off a usb cable)
power connectors for the board and battery (see picture)
power adapter/plug ( I used RS # 274-1569)
power jack (RS # 274-1577)
I used some plexiglass I had laying around
And finally for my housing an Altoids can
Tools:
Solder Iron and solder
Helping hands (sure are helpful)
light (helps to be able to see what is going on)
pliers
side cutters
Dremel with various bits (hacksaw and or tin snips can be used instead)
super glue
drill and drill bits
Sharp knife (always useful at some point)
Electrical Tape
Multimeter
Well hope I did not forget anything :)

use a recharger for cell fones, they are great 12 to 5 volts power sources, and are cheap too.
so, you can use a simplier design and have the same ligths running xD
