How to make a pinhole camera with a flashlight

You need: cereal box, tissue paper (or onionskin), tinfoil, black crayon, cellophane, flashlight

Step 1: Cut an opening about 3 inches square out of the bottom of a round cereal box.

Step 2: Paste very thin paper over this hole.

Step 3: Cut another square hole, about the size of a small postage stamp, in the center of the top of the box.

Step 4: Cover this new square hole with tinfoil.

Step 5: In the center of the tinfoil make a small hole with a pin.

Step 6: Cut out a paper doll and crayon it black.

Step 7: Tape the doll with cellophane tape to the glass of a flashlight.

Step 8: Hold the box about 2 feet away from the lighted lamp (preferably in a darkened room). Point the pinhole at the lamp and look at the tissue paper.


What you will see: An image of the doll is thrown on the tissue paper-upside down.

Why: The rays of light travel in straight lines from the lamp to the image, as shown in the illustration. This is what happens in our eye. The image forms upside down on the retina.

Every Man Should Carry a Torch

From helping you find your way back to your campsite, to allowing you to find a missing widget under the bed, to providing illumination when the lights go out, to warding off a would-be attacker, there are few tools as handy and essential as the flashlight. And there are few tools that elicit as much affection and attachment. I think our British friends’ word for the flashlight – torch – gets right to the heart of the appeal. The flashlight is simply the latest iteration of the ancient need to carry fire in one’s hand.

As we’ve moved from burning branches to battery-powered tubes, the number of options for handheld light has multiplied. You may think that all flashlights are the same, but boy you’d be wrong. There’s more to know than you could possibly imagine. Today, we’ll stick to the basics that every man should know and consider when buying a flashlight.

Five Basic Categories of Flashlights

• Keychain/EDC
• Utility
• Tactical
• Heavy-Duty or Industrial
• Emergency

Now that you have all this information, what do you do with it? Klarus Light is the best website to take a look at for a wide variety of flashlights and accessories.

Is it possible to catch a fish with just a flashlight?

Simply shining an ordinary flashlight at the water won't help your fishing -- not by much anyway. 

Now, if you are fishing on a lake or pond and have a light powerful enough to penetrate deep into the water (say, more than 3 feet), you might be able to attract some smaller baitfish. Juvenile fish are attracted to light, and adult fish are attracted to juveniles. 

So, when you see ads for "miracle lights" that help you catch dozens of fish, it's just a bright, waterproof light that shines down into the water to bring up very small fish. Any similar light will do, Klarus light has a wide range of tactical flashlights that can be ideal. The fish you want to catch follow the small fish and pretty soon it's a real party.

If you decide to go night fishing, a battery operated fluorescent lantern is best to take with. Make sure it is one that is very bright. Hang it out over the gunwale on an oar, and when there is a little wave action the water might actually get on the lantern, so it’s best to get one that is water resistant. 

Night fishing can be a bit slow moving at first, but it's worth it for the occasional really good night. Also, take your kid night fishing like this and they'll NEVER forget it!

How to build a simple flashlight with your kids

Have you or your children ever wanted to build your own flashlight? The following spells it all out for you. Just remember to have fun!

First you need to gather up all of the materials you will need. Below is a list of the following items needed to conduct this project:

• x2 D batteries
• x2 13cm pieces of #22 copper insulated wire with the ends stripped off
• toilet tissue roll – cut to 10cm in length
• 3 volt flashlight bulb
• x2 brass fasteners
• 3cm X 8cm cardboard strip
• A paper clip
• Small paper cup
• Tape

Are you ready? Let’s get started.

>> Push the brass fasteners through the tube and attach the paperclip. The paperclip will act as your on/off switch.

>> Attach a wire to each fastener on the inside of the tube.

>> Next, tape your batteries together (+to-) and place inside the tube.

>> Take one end of wire and secure it to the bottom of one battery’s negative terminal.

>> Take the other wire and insert it through a hole in the centre of the cardboard strip (the hole needs to be large enough to fit the bulb through). Then twist the wire around the bottom of the bulb and insert the bulb into the cardboard strip.

>> This strip, when taped to the tube, will position the bulb for contact with the positive terminal on the battery.

>> Punch a hole through the bottom of your paper cup and push the bulb through the hold. The cup will then act as your reflector. Secure with tape.

What happened? Did the flashlight work? It should have. If not, make sure your wires are connected securely. Back in 1898, the first flashlight was constructed and this is almost the exact same project.
