Avoiding Electrocution

No plans or books today, but browsing some of my Word docs. I figured some might find this article both enlightening and entertaining.

"Avoiding Electrocution" is a short article that I found many years ago. It was originally published in 2002 on the "Atomic" site, dealing with computer electronics. The author communicated the subject matter very well, while still being quite entertaining. Hopefully you will think so as well, I only wish I could write like that.

Early on I was taught that a live wire is much like a pipe line, Where the size of the pipe represents amperage and the pressure in the pipe represents volts. The analogy holds true here too. If you stand in front of a large pipe (high amperage) but there is low pressure in the pipe (low voltage), suddenly opening a valve will get you wet but that is about it. However if you increase the pipe press (voltage) to 120 or 240 psi, when you open that valve, they will be scraping you off the far wall, or in the case of voltage you will be lucky if you just look like the picture below.

Motors And Electrical Power

So, slow getting going today, figured a post would at least keep me active. " Step-By-Step Knifemaking" by David Boye has become a bit of a classic "must" for the novice pursuing the art of knifemaking. Everything is covered in this fine volume from setting up shop to etching designs into the steel. It may still be available as publisher remainders or in the used market. I had two a hardcover and a paperback. In a culling of my bookshelves to make more room, the paperback made it's way into the used market.

Below is a picture of the cover and an example of the many knife designs that Mr. Boye has produced. Many of these designs are covered in his step-by-step instructions.

In, setting up shop, is a basic but interesting article on motors and electrical requirements for setting up the small shop. Some of his comparisons rang a bell with me. Relating amps to the flow of water in a pipe and volts to the pressure pushing that water, helps to clarify, and is an analogy I was taught early on, obviously it stuck.

So it's basic, a little different, but interesting light reading on the subject.
