Wilderness Survival Gear For Hiking And Backpacking
As backpacking and hiking equipment has become more sophisticated, people have gotten more daring, and at times even reckless. Humans, it seems, have an inherent need to prove they can survive in the wilderness. More and more hikers and rock climbers are backpacking deeper and deeper into the unknown wilds. These are not your weekend campers. Rather, these are serious nature lovers who look and find there own truth, each time they venture outdoors. There is obvious gear and equipment they utilize, both traditional and futuristic. This article will attempt to verify some of the accepted items to pack, as well as some new options to think about.
When packing, it doesn't matter what type of activity you are going to undertake, there several unwritten rules one has to abide by. First, you must pack light, and include the basics of food, water and a way to purify it, first aid kit, and some kind of fire starter. A map and compass, so you have an idea on where you're going and how to get there. Include some type of multipurpose knife or tool that can perform a number of tasks, from cutting branches to removing splinters. Don't forget your sunglasses and some sun screen. A flashlight and extra batteries, even if you are taking some type of lamp. Now, this is very important. Even though you are trying to keep it light, you must take extra food, as well as rain wear and extra clothing, including a hat.
There are two schools of thought when it comes to the use of futuristic equipment. I'm referring of course to GPS and beacon technology. Purists don't want anything electronic, and the other camp feels they should take advantage of anything that will get them home safely. The current expense of these devices does make them cost prohibitive. Also, in the case of an injury, these units don't give the precise location of a victim, so you will still need some sort of signaling device, like a mirror or whistle.
I don't feel that the future must all be electronic. I have come up with a patent pending concept that will satisfy both camps, and is so cost effective, anyone that backpacks, hikes, rock climbs, and camps, will be able to afford. In this day and age of electronics, I have devised something that is completely mechanical. There are no batteries or bad reception to worry about. Surviving in the wilderness should never come to mean survival. In this day and age, someone who is lost should only be thinking about being rescued.That is why we needThe LifeTracker.
The LifeTracker makes it possible for people to be found before panic on both sides will ever set in. It not only will save lives, but millions of dollars in search and rescue man hours. The LifeTracker is a device that in case of an emergency will, with the pull of a cord, jettisons a heavy gauge red balloon attached to a 1000 ft fishing line up high enough for searchers or a rescue plane to see. The LifeTracker is a series of 3 different products designed to locate anyone lost in the wilderness, in hours rather than days.
The LifeTracker Belt is...4" wide with pockets on the outside to store a thermal blanket and other survival supplies.
The LifeTracker Vest...Using the same concept as the "Belt" the vest inner side unzips to release a folded lean-to tent complete with telescopic 3 ft poles. Some people will prefer a vest and are willing to pay extra for the complete survival package. This offers a great option, and like the "Belt", is very marketable.
The LifeTracker Flare Gun...Flare guns are very expensive and, of course, the flare only has a short life. With a small adjustment to the LifeTracker Device, it can easily be kept in a lightweight pistol, that can be stored in any backpack, vehicle, boat or plane. It might even have military use.
The LifeTracker Series can be manufactured and sold inexpensively enough so that anyone who camps, hikes, rock climbs, or just ventures into the wilderness, will want to include it as part of their gear. Even if the rescue device is never activated, the gear becomes part of everyday wilderness attire.

How to build my own reflector scope from scratch (not using any kit)? - beginner question?
I'm planning on making an 8"-10" reflector scope using everyday things (w/ some fabricated stuff). Is there any specifics on which kind of concave mirror should I use? Or a vanity mirror is already good enough? About the second (flat and ellipse) mirror, how will i know the size and the distance from the main mirror? How they are related? And how they are computed if ever. Last thing.. making an eye piece, (planning on using a pvc pipe).. from what I saw in my 3" scope, the smaller the diameter of the concave glass, the better magnification.
So that's pretty much the plan. Not sure though how hard or easy it is making my own Newtonian telescope. Please give your comments. And tell my if I'm insane with my plan. I only know basics. I'm just a big fan of scopes. 
EDIT: some vanity mirrors have concave shape. You can tell that because you apprear bigger in the reflection.
What will happen if you just use cheap mirrors like a vanity mirror??
Fifty years ago, it used to be very common for people to make their own telescopes. Nowadays it has become very rare, because commercial telescopes have become relatively inexpensive. One result of this is that it is very hard to find the parts needed to build your own scope. Unless you have a very strong motivation to learn how to do this, and to track down the parts needed, I wouldn't recommend building your own scope. Because the parts are hard to find, they are very expensive, and a home made telescope will cost many times more than a commercially built telescope. Labour is so much cheaper in China where almost all telescopes are made nowadays.
From your question, it's clear you have little idea of what's involved. Any telescope uses a "first surface" (aluminized on the front) precision ground mirror as its primary. A vanity mirror is a "second surface" (aluminized on the back) mirror with nowhere near the precision to form an image. It is possible to grind and polish such a mirror yourself; there are kits available. Aluminizing the mirror must be done by a professional mirror coater.
