Picture of Film Canister Flashlight
IMG_0299.JPG
This film canister flashlight was more fun to build then an Altoids flashlight and feels so much more comfortable in our hands. Don't get us wrong, the Altoids tins are great. We just love the handiness of this little guy and no metal shavings when you drill into it!. We had it out by the pool as a nice affect, hanging in the basement where we needed extra light, by Cool Cat's bed as a night light, Ally Cat took it to school to hang in her locker, and of course we all use it as a flashlight.

Step 1: Materials

Picture of Materials
3 Volt Battery (not pictured)
1 to 3 Magnets (depends on your method)
2 Wires (of different color and about five inches long)
Drill
Electrical Tape
Film Canister
Hot Glue
LED
LED Holder
Toggle Switch (not pictured)
Wire Cutters

Step 2: Magnets

The first magnet is to hold the flashlight up on magnetic surfaces.

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.

Showed this to my partner and she loved it! Been trying to find uses for the constant accumulation of prescription bottles!

I am glad she liked it! Have you shown her our LED candle?

I think the hardest part of this project may be simply finding a film can. Where did you get yours, grandpa's abandoned darkroom?
We had a project that used
We hear that a lot but they can be found on e-bay pretty easily. We also have them at catsscienceclub.com but look around you never know what you may find. Old cleaned out prescription bottles should work, for example.

If making such flashlights is fun and/or educational, this is a fine project. But, you can buy cheap LED flashlights for less than the cost of just one toggle switch.
I made two and sent with my girls to Girl Scout camp. They said it was very helpful and they were happy they had them.

I bet that to improve the beam a small parabolic mirror could be stolen off a dollar store flashlight. Cool project, I always love toggle switches.
Very cool. Now if I could figure out away to not have to solder, I could use this with my elementary class. :-)
simple, where the solder joints are required, such as the switch and the led ect, just twist the wire around the terminal then either electrical tape it or my preferred choice is to slide some heat shrink tubing over the join, then use a lighter, heat gun or even a hairdryer to shrink the tubing, that is the strongest connection without soldering ;) hope that helped :)
I haven't used it, but I've seen a conductive glue.
Thank you!

I think the altoids smalls work best o yea and why dont u use 3leds

The lid of the film canister is perfect for the one light but we like your idea. Perhaps we will try that. We have some fine tuning to this "flashlight" that we are going to share this coming up week.
Nice Idea to made a flashlight with those simple parts. Especially the battery holder with two magnets :) Maybe you should describe which type of LED you used, that can be supplied by an 3 V battery.

The picture where you wrapped the wire around the magnet made me think of Iron Man. I like this a lot :)
