antenna basics
Antennas, to quote a friend, are one of life's eternal mysteries. "All I'm totally certain of is that any antenna is better than no antenna and the antenna should preferably erected as high and be as long as is possible or desirable". Here we will discuss the very basics of antennas including the the amazing terminated tilted folded dipole antenna. Each type of antenna will eventually have its own page.

Antennas, to quote a friend, are one of life's eternal mysteries. The basic antenna The most basic antenna is called "a quarter wave vertical", it is a quarter wavelength long and is a vertical radiator. This type of antenna relies upon an "artificial ground" of either drooping radials or a car body to act as ground.

Raspberry Pi as an Ad Blocking Access Point
This tutorial will show you how to use your Raspberry Pi as a WiFi access point that blocks ads by default for any devices using it. This is really neat in that it would work for your Android or iOS device, your Xbox 360, TiVo, laptop, and more without needing to customize any of those devices other than to use your Raspberry Pi as the access point for WiFi. Using an ad-blocker can be useful for conserving bandwidth, helping out low-power devices, or for keeping your sanity while browsing the web! I do suggest whitelisting your favorite ad-supported sites so that you can continue to support them (this tutorial shows how to do this as well). It's not easy keeping up with those wily ad serving companies so we'll also setup a way to keep your ad blocking lists up to date as part of this tutorial. I used many pages as inspiration in order to set this up, including, but not limited to:
Apple’s Middle finger: It’s Pointed at You
Let’s get this clear right off the start: Apple makes some absolutely fantastic products. The issue is not with the quality of their products, but the attitude and manner in which the company operates. They are giving their customers the middle finger, and for some reason the customers are thanking them for it. I make the argument that it doesn’t have to be this way. If we want Apple to stop treating their customers with disrespect, we need to stop praising them for doing so. Apple makes luxury products.

Hard Disk Drive Magnets For Wind Turbines
Obtain super strong magnets from old hard disk drives to use in wind turbine alternators home > windThe most expensive parts of a wind turbinealternator are the magnets and the enamelled magnet wire. In a previous article we have introduced cheap and easy to make PVC wind turbine blades. Hard Disk Drive Magnets 50% of the world's neodymium magnets are currently used in computer hard disk drives (HDD) with each HDD typically containing two magnets. Extracting the magnets from an old hard drive is very easy - usually just a small selection of screwdrivers is required. This can be difficult - the easiest way is to put one corner of the backing plate into a bench vice and bend the other corner of the plate using a pair of vice grips. The following short video shows the full process from opening the hard disk drive, extracting the magnets on their backing plates, to removing those backing plates to leave just the magnets ready to be used.WARNING!

Top 10 Things You Can Upgrade with a Little Electronics Hacking
it is a skill to do a good solder joint, it comes with LOTS of practice. so most people who rarely do it will ever get good at it. Bingo. Of course, part of the issue is having a soldering iron at the right temp with a properly tinned tip. Newbies aren't using soldering stations but a cheap iron they got at rat shack (You have questions? We have deer-in-the-headlights... erm... answers!). I don't expect to ever master tricky stuff like smts or even multilayer pcbs so I'm not much better then a newbie, anyway - and I totally suck at sweating pipe joints. Ah, well... SMT is actually a bit better than through-hole once you get the hang of it.
