Generally I exorcise this worry by purchasing wool-wear. But now seems like a critical moment to get my emergency skills in order—some two years into the recession and 22 months from the Earth's collision with Planet X. To say nothing of snowpocalypse. My savings dwindling, I retreated to an old farm in the Catskills to ride out the winter and, with the assistance of five guides, learn how to live in the wild. Methodology I embarked on a series of rigorous field tests. Since I am a city boy and a bit soft, I also looked for qualities that would satisfy my friend and former colleague at Adventure, the hardy Paul Rouse.

NEETS - HvWiki From HvWiki NEETS is an acronym for United States Navy Electricity & Electronics Training Series. The NEETS series consists of 24 modules, each covering a specific topic in the field of electricity and electronics. Because it is a work of the US government and therefore in the Public Domain, contents of the NEETS documents may be copied verbatim without restriction. This may be useful for adding content to HVWiki without concern of copyright infringement, for reference material, and general electronics training. Purpose The Navy Electricity and Electronics Training Series (NEETS) was developed for use by personnel in many electrical and electronic related Navy careers. The series is designed to give small amounts of information that can be easily digested before advancing further into the more complex material. Contents Module 7 - Introduction to Solid-State Devices and Power Supplies is similar to module 6, but it is in reference to solid-state devices. Module 8 - Introduction to Amplifiers

Top 10 Essential DIY Skills That Aren't as Hard as You Think I think it depends on your definition of "maintenance." I wouldn't hesitate to change my own oil or something like that but I wouldn't dream of replacing a radiator myself. That isn't my idea of "maintenance." That's fixing something. Sorry you are afraid of doing that stuff, but even a complete engine rebuild is easy to do, and no you don't need "special tools" unless you call things beyond a hammer and screwdriver "special" I can do a front end alignment on a car in my driveway with a tape measure and a couple of carpenters squares along with the wrenches most people would have. Also if you do buy the cheap but special tools you can replace your own tires and balance them better than the "laser computerized" balance machine at the tire place. In fact the only expensive special tools I need are a Crane and engine run stand. Danger? This is why I don't take my cars to the dealer for any routine maintenance. Aside from that, dealers are inconvenient.
