I had made some Altoids flashlights for my kids and they loved them. However, I found them to be rather expensive to build after running to Radio Shack and buying all the parts. Then I figured out a way to make this "Super Light", with 27 LEDs, lenses over the LEDs, a 3 position push button switch, reflectors for the LEDs and I only had to purchase 2 things to do it. And the whole thing cost me less than $5 when you don't include the electrical tape, wire, hot glue, and solder (these are all things I keep on hand for making stuff anyways). Even the 3 LEDs in the front are brighter than the 4 led array in my original flashlights due to the built in reflector. Honestly, this was almost easier to build than the models I built before. And the biggest bonus is the fact that the cost was less than half and it's more functional.
(A friend borrowed my dremel and hasn't given it back so I was only able to do the pics up to the point of cutting the tin. As soon as I get it back, I'll finish adding picks to all the steps.)
Step 1: Materials:
1. Empty ALTOIDS tin (or similar mint tin) $1-2
2. 27 LED worklight / flashlight from Harbor Freight Tools (Item#67227) $3
