Homemade Lamps from Everyday Objects Having the ability to create light without needing electricity should be part of everyone’s emergency essentials. While flashlights are certainly helpful, batteries quickly die out so having a store of candles on hand can provide the light and morale boost that one needs to make it through a dark night or two. But what if you didn’t have any candles available? Fortunately there are very simple ways to make homemade lamps from everyday objects found around the house. How a Lamp Works Both oil lamps and candles are able to continually burn their fuel (wax or oil) through a process called capillary action. Understanding this is the key to creating many different types of wicks for your homemade lamps. Making a Tuna Fish Can Oil Lamp Here’s a simple example of how to make your own oil lamp using a tuna fish can. Tuna CanVegetable Oil, Olive Oil or any other cooking oilOld Cotton T-Shirt, Rag, or SockNail (or something sharp to poke a hole through the top of the tuna can) Light the wick.
Snares And Traps Disclaimer: Traps are presented for information purposes only, they are dangerous, some lethally so. Using them is also illegal in all likelihood. Don't use them except in a survival situation. SPRING SNARE: Game running through the snare disengages the trigger bar,and the prey is flung off the ground. Use on game trails or in gaps through rocks or hedges. BAITED SNARE: Construct as for spring snare but using the release mechanism shown. LEG SNARE : Push a natural fork or two sticks tied together into the ground. PLATFORM TRAP: Site over a small depression on the game trail. FIGURE 4 DEADFALL : A simple and effective deadfall trap, can be made to any size. TRIPWIRE DEADFALL : A heavy log is suspended over a busy game trail, trips the wire and pulls a retaining bar from under two short pegs secured in a tree trunk. SPEAR DEADFALL : Same as tripwire deadfall but utilizing rocks to add weight and sharpened sticks to add trauma to the crushing blow.
Compass Alternatives Compass Instructions and Alternatives ( or How to Find Your Way With or Without a Compass ) Copyright © 1999,2004 by Robert Wayne Atkins, P.E. All Rights Reserved. Click Here for a Microsoft WORD printer friendly copy of this article. A good compass has been a valuable asset to explorers, travelers, and hunters for many centuries. Let's begin be examining the primary function of a compass. On some compasses the letters are on a dial on the outside border of the compass. In the picture of the black compass below, the N, E, S, and W are printed on a floating dial inside the compass. Regardless of which type of compass you have, the relative position of N, E, S, and W in relation to one another is always the same. Many camping supply stores, including WalMart, sometimes carry a small compass that is part of a multi-function unit that usually includes a miniature thermometer and a whistle (and sometimes a folding magnifying glass).

Hobo Stove | Practical Survivor Urban survival is a tricky subject to discuss. There are advantages to urban survival. Anywhere you look there are items in trash cans and dumpsters that can be used to improve a survival situation. Cardboard boxes can be used for shelter, newspapers can be used for insulation and to the practical survivor another persons trash can be a treasure. In this case we will use a coffee can to build a stove. Whether you call it a hobo stove, can stove, or just a survival stove, this is a cheap effective way to both cook and stay warm. Keep an open mind during any survival situation. Whether backpacking, camping, or surviving, having a way to cook can make a huge difference. A coffee can or large vegetable/ravioli can will allow you to build a stove and cook. Items used to build this stove: * Coffee can * Can opener * Tin snips * Drill and drill bits * Metal coat hanger There are many methods that could be used to build this stove. The top side of a coffee can is already opened. Materials:
How to make a tool set Life without tools is barbaric. But even simple tools can be expensive in rural parts of developing countries. Import duties bump the costs up higher than they are in the States or elsewhere, and sometimes only low-quality brands are available anyway. So, to hold off future barbarians, we'd like to show how to build a simple tool set on a very low budget. Larry Bentley, the man who figured out how to make these tools, said a wise thing: "Without tools, kids don't take stuff apart, and without taking stuff apart, you don't learn how things work." These tools, Bentley says, could be in the hands of the next William Kamkambwa,who made a working wind power generator from backyard scraps in a village in Malawi. Here's Larry's quick guide to DIY tools. The tools in this guide: Saw Pliers Wooden vice Wood drill bit / star drill bit Chisel Strap hinge vice

How To Heat Up Your Room Using Just a Candle: This heater is a multi-core steel and ceramic radiator assembly, suspended above the candle on a solid steel stand. The radiator absorbs and concentrates the thermal energy of the candle and converts it into dry radiant space heat. If you burn candles, now you can add their heat to your home or office. There is also an “electric candle” option that uses a 60 watt quartz halogen lamp; that works out to about 6 cents for 10 hours of “burn” time. “Steel has the ability to approach the temperature of its heat source,” says the inventor, “so the solid steel inner core will go as high as 550° Fahrenheit. That high inner temperature is mitigated to a very warm 160° to 180° on the outer surface. The simple elegant design has no moving parts. What’s new for 2008 is an “electric candle” option that takes advantage of the fact that 90% of the energy that goes into an incandescent lamp is “wasted” as heat. The electric candle is pictured below:
I Will Knot! Building a DIY microscope This is a story of what happens when a foolish scientist screws stuff up. It’s the story of a DIY microscope, and how it all went terribly wrong. I tried. I really did. I read the instructions through five times. Last week I came across the instructions to make a do-it-yourself microscope. I went out and got all the parts I would need. Here’s the idea for the microscope, invented by Kenji Yoshino, a Science Learning Center post-baccalaureate fellow at Grinnell College. Figure 2. But mine came out looking very different indeed. We started by trying to drill the wood and the Plexiglas to fit the screws in and make a base and a stage for the microscope. Bad choice. But even if you use masking tape or heat, you have to start with a very small drill bit, and then use larger and larger bits until you get a hole that is the right size. Despite the cracks, in the end we got the holes! And here’s where I made a BIG mistake. So I put the lens in the smaller piece. Finally, we put in the light.
