Step 1: Materials
1 to 3 Magnets (depends on your method)
2 Wires (of different color and about five inches long)
Toggle Switch (not pictured)
Step 2: Magnets
Place a bead of glue into the bottom of the film canister and add your magnet. This will need to be a fairly strong magnet to hold the canister up. We found 1 inch ceramic magnets worked well and did not cost to much.
Step 3: Battery Holder Option 1
Make sure that the magnets will attract each other and not repel. We suggest marking the magnets.
Expose a large amount of wire, nearly 1 1/2 inches, on each of your wires.
Wrap your wire through the magnet or around the magnet if yours does not have holes in it. Do this for both wires.
Check the polarity of the magnets to make sure they will be able to be attracted to each other and the magnet in the bottom of the film canister.
Place your 3 volt battery between your two wired up magnets. Take note of which wire was touching the positive side and which wire was touching the negative side of the battery. In our pictures we used black for negative and gray for positive.
Glue the magnets into place by gluing the the top, bottom, and a side of your "battery holder".
Step 4: Battery Holder Option 2
Strip the wires leaving about 1/4 inch of wire exposed.
Place the wire on to 3 volt coin battery. Using the electrical tape, tape the wires on to opposite ends of the battery. Make a note of which wire is on the negative end and which wire is on the positive end. In our pictures we have black as negative and gray as positive.
Step 5: Cut and Splice
Splice the wires connected to the battery at both ends of the extra black (negative) wire.
Step 6: Prepare the Toggle Switch
Take the negative wire that is connected to the "battery holder" and wrap it around the outside prong of the toggle switch. Solder the wire to the switch.
Take the extra negative wire (our black wire) and connect that to the center prong on the switch. Solder it on.
Now your switch is ready!
Step 7: Connecting the LED
Take the negative wire (black) that is connected to the toggle switch and wrap it around the negative leg of the LED. Solder in place.
Take the positive wire (grey) that is connected to the "battery holder" and wrap that around the positive end of the LED. Solder.
Does the light turn on? No? Try the switch ;-)
Step 8: Prepare the Canister
Drill another hole into the lid of the canister. It was easier to have the lid on the canister while drilling. This hole is for the LED holder. We found that it was a good idea to punch a hole into the lid with a nail and then drill. The drill bit needs to be the right size for the LED holder. Better to start a bit smaller and work your way to a bigger hole until the holder fits.
Insert LED holder into lid.
Step 9: Put Together
Push LED into LED holder.
Hot glue (we actually use a low temp. glue gun) the exposed wires but do not glue to the side of the canister or you may not be able to close the lid. Wires will stick out.
Snap on lid after glue dries.
