Intro: El-Cheapo Flashlight Hack
I really needed a UV flashlight for my radioactive materials because they look 2000000 times more cooler under UV than anything else. My parents went to a party and they gave these cool little flashlights away for party favors. I had the UV LED's so I decided to mod them for less than 5 cents!
Step 1: Materials
1 Small screwdriver
1 Pair of scissors or wire snips
1-2 ultraviolet or any color of led you want
1 something to test your UV light on (optional)
Step 2: Unscrewy
Grab your screwdriver and open up the case, it should look something like the image below.
Step 3: Remove and Replace
Remove the Ultra bright led and shape the UV led the same way as the Ultra Bright one, make sure you know which end is positive and which end is negative!!!! Install your UV LED the same way your UB LED was.
Step 4: Reassemble
I try and and reassemble my flashlight by sandwiching the 2 halves hot dog wise because that push button falls out easy and so does the actual switch so try and do this swiftly. Once their sandwiched, screw in all of your screws and test it out. You should test it as soon as your 2 halves are together but I felt lucky so I screwed in all the screws and then tried it.
Step 5: Finished!!!!!
You can now enjoy the full benefits of a UV flashlight (or torch as some of you call it) and freak out your friends claiming that your uranium glass are kryptonite crystals!
