Never lose those pesky keys again! This Instructable will teach you how to make a simple and stylish glow fob that can easily be attached to your keys or anything else you may want to keep track of more efficiently in the dark.
I’m the type of person that misplaces everything, keys, pocket knives, wallets, glasses, cell phones; nothing is safe once I’ve laid my hands on it. After losing my keys for the millionth time I decided I needed to do something about it. For a while I tried one of those gadgets that beeps loudly when you whistle allowing you to home in on the location of your keys, the problem with that was that it would go off at any loud noise and after it decided to go off several times during class I decided it was time to find a better solution. What I came up with was a simple yet effective glow in the dark fob. Now I know what some of you are thinking, “What use is a glow in the dark fob when I’m trying to find my key’s during the day?” and the simple answer is that it isn’t very much use at all, but there have been many times when I misplaced something during the day, searched for it without any luck, and found it by the bright glow of the fob once it got dark.
So for those of you out there who share my inability to keep track of things please feel free to read on and learn how to make a glow in the dark fob that is both functional and stylish.
Step 1: Materials & Tools
20 minute epoxy: You need at least 20 minutes of working time, instant and 5 minute epoxy sets up way to fast.
Glow Powder: There are many colors to choose from, however, I suggest V10 Green it glows the brightest and longest. Glow powder can be purchased on Amazon or Ebay, I bought a ½ ounce for around 8 dollars.
¼” outside diameter flexible clear plastic tubing: can be purchase very inexpensively at any hardware store. 1 foot of tubing should be more than enough.
Metal or plastic tubing that will snuggly fit the outside diameter of the rubber tubing. (I used an aluminum arrow that I got for free from the local archery shop).
Spring rings (key rings): you probably have some lying around the house.
Pipe cutter (can be purchased an any home improvement store for under 5 dollars).
Xacto knife or other sharp blade.
6ml syringe (can be purchased for under a dollar at tractor supply).
Sand paper (220 grit would be fine). The blue pencil length tool in the picture is my sand paper, it's called a sanding stick and can be purchased from jewelry supply companies like Rio Grande.
Jeweler’s files (not necessary but helpful).
Power drill and 3/32” or 1/8” drill bit.
Power sander (not necessary but helpful).
Something to thoroughly mix epoxy with, (I use an old sculpting tool, but a tooth pick or popsicle stick would work fine).
Wax paper or small disposable container to mix epoxy in.
