With the days getting shorter and shorter I figured I'd improve an old underwater flashlight my dad had lying around.
The basic idea is to replace the light bulb with some bright white LEDs to up the power and efficiency of it. I'll even be able to use it while diving since I won't have to damage the case!
And now for some pics of the building:

The aluminum sheet with a grid of holes drilled into it for the LEDs

The hardware I needed to buy

-LEDs
-Wire
-Heat shrinking
-Battery holders (needed to reach 6 volts which is required by the LEDs)
-Resistors
-9v battery connections
A total cost or roughly $70
During the soldering process:

About half the LEDs done

Really need to get a proper work bench :)

All of the LEDs done
