A mini flashlight, commonly called a torch, requires batteries to power its incandescent bulb. You can make a mini "shaking" torch that will never need batteries to power its LED bulb. A few hardware and hobby store supplies are needed, but no electrical or mechanical skills. As its name implies, your mini shaking torch only needs to be shaken to light up.

Difficulty: Moderately Easy

Things You'll Need:

Newspaper
32-gauge copper wire spool
Wire cutters
White LED bulb
Two rare earth magnets
Plastic 35mm film can
Duct tape
Ruler
Utility knife
Soldering iron
Solder

1
Put a sheet of newspaper on a table. Stand the plastic 35mm film can on the newspaper with the film lid facing up. Remove the film lid.
2
Measure one inch up from the bottom of the plastic 35mm film can. Wrap duct tape around the plastic 35mm film can at the one-inch mark.
3
Measure one inch down from the top of the plastic 35mm film can. Wrap duct tape around the plastic 35mm film can at the one-inch mark.
4
Measure six inches from the end of the copper wire on the spool. Place the copper wire at the six-inch mark against the duct tape at the bottom of the plastic 35mm film can.
5
Wind the copper wire around the plastic 35mm film can and up to the duct tape at the top. Wind the copper wire around the duct tape at the top and then down around the plastic 35mm film can to the duct tape at the bottom.
6
Continue winding the copper wire up and down the plastic 35mm film can an additional 38 times.
7
Wind the copper wire around the plastic 35mm film can an additional time if necessary so that the copper wire is at the top of the plastic 35mm film can.
8
Cut the copper wire off the copper wire spool with the wire cutters.
9
Place the film lid of the plastic 35mm film can on the newspaper. Cut a hole in the center of the film lid with the utility knife.
10
Push the white LED bulb through the hole from the bottom of the film lid so that the white LED bulb is peeking out of the top.
11
Solder the end of the copper wire that is at the top of the plastic 35mm film can to one of the two pins that are attached to the bottom of the white LED bulb. Let the solder cool for a minute.
12
Solder the end of the copper wire that is at the bottom of the plastic 35mm film can to the other pin that is attached to the bottom of the white LED bulb. Let the solder cool for a minute.

Flashlights are not like they used to be. When I usually think of a flashlight, it's usually a Mag-lite, or the tacky plastic protected ones I grew up with.
The TK40 LED Flashlight by Fenix cleared up a lot of things, it's innovative technology and power changed my perspective. LEDs have become the standard because they are more powerful than ever, they are lighter, and they have plenty of brightness for most home, and casual users.
Some people prefer to have a flashlight for many reasons. The Fenix LED flashlight is a very potent and indestructible tool. This is not the run of the mill flashlight. Excellently constructed from aircraft grade T-S aluminum.
630 lumen is an incredible amount of radiance, and the Fenix is said to be the Brightest battery powered LED Flashlight on Earth! The one thing you will never worry about, and that's having a Mammoth portion of light anytime you need it. With a beam projection of 984 Ft. you can cover a very large area.
Many search and rescue teams rely on the Fenix, because they know they have several light settings, and because it can flash emergency, strobe, and SOS signals. 4 strobe functions in all!
Always be prepared for the elements by being safety minded. Not having the basic emergency supplies, could make for a very bad day. Waterproof as well as being impervious to damage, stand it up to utilize the LED flashlight as an ambient lamp.
A clear protective coated glass lens is resistant to shatter. Rubber protects the switches from damage, dust and water. A lanyard and shoulder strap come with the flashlight, as well as 2 extra O Rings to lock water out.
The replaceable Cree LED bulb will give you 50, 000 hours of run cycle. Common AA batteries breath life into the Fenix, easy to find and plentiful. The magnificent amount of light thrown by the Fenix LED gives any million candle spotlight a challenge to keep up with. It blows most other lights away!
Indestructible and intelligent, it's the perfect partner on any work site. The light only weighs a little more than half pound before batteries are inserted.
Technology plays a role with the Fenix as well. The setting last used is remembered, so next time you fire it up, it's just the way you left it. 4 different settings are given for lumen and energy consumption.
Turbo is the most intense setting, and the manufacturer recommends not more than 15 minutes continuous use on this setting.
If your profession has anything to do with search and rescue, public service, safety inspection, patrol, exploration, night guide, or many other commanding situations, then this LED flashlight has the portability, reputation, and indestructibility your looking for. Namby Pamby is no name for this good looking Sherman Tank.
You'll be astounded by the power, even if your just a flashlight buff and don't plan on hiking into the Rockey Mountains for a week. It's perfect for camping, hiking, Emergency road situations, exploring the attic, and can protect one at the same time! The ability take on any storm, it's a fantastic light that can go anywhere!
The awesome power of the Planets Brightest Battery LED Flashlight will really be unmistakable when you switch it on. Emergency Flashing Strobes, aircraft grade aluminum construction, and waterproof design make this an awesome tool.
Any search and rescue team you assemble will need the right lighting for the job. Just remember, before you head out like John McClane in "Die Hard", or walk your furry friends. Choose a tool sturdy enough to handle it.
