WoW Druid Talent Tree Build in WotLK - Where to Spend Your Talent Points
The druid is a shape shifting hybrid class which allows you to approach many different play styles and this is the reason why it is one of the most versatile classes in the entire game. Druids of every spec can find a role for themselves at the end-game whether it's raiding or PvP.
Just like with the rest of the classes in World of Warcraft the talents for druids are split into three categories, or trees:
- The Balance tree which focuses on damage spells that will make the druid a very efficient spell damage dealer.
- The Feral Combat tree which focuses on using the shape shifting druid forms of cat, bear and dire bear, each of these focusing in turn on either tanking - Bear and Dire Bear - or on melee DPS - Cat form.
- The Restoration tree focuses on healing spells, making the druid a very efficient healer, especially because of the Tree of Life form that druids learn by investing in this talent tree.
Like we said in the beginning the druid class is a hybrid class and this means that each druid talent tree will definitely contain some talents which will be useful and sometimes necessary when specializing in any one of the other trees. Let's take a look at what a druid talent tree can offer.
For instance:
- Some Feral Combat talents will modify your maximum mana which you would need large amounts of if specializing in the Moonkin form;
- some Balance talents will modify the cost of healing spells which is crucial for any good healer, while others will be helpful when in the feral forms.
- Some Restoration talents like Furor, will give the druid rage when they switch into either Cat or Bear Form, while others like Natural Shape shifter will reduce the mana cost of shape shifting by thirty percent.

ATX Power Supply - The Simplest Way To Repair It
I had stopped repairing ATX power supply many years back due to the new one cost very cheap. It's not worth to repair it because the spare parts sometimes were much more expensive than getting a new power supply. Searching for ATX power supply spare parts was not easy as many of them you can't even find them on the internet. Not only that, many complicated and different designed by power supply manufacturers had eaten up our precious troubleshooting time too because of we need time to understand how all these different designed power supply work.
Some of the power supply designs were using the PWM IC (UC3842) and power FET, some use the double transistors while some use only a single power IC in the primary side. Because of the manufacturers wants the design to be made into compact size, many secondary or even primary power supply circuit were build into a modular board (smaller board). This made troubleshooting even more difficult because many times the meter's probe can't reach to the testing point.
The real reason why I had stopped repairing ATX power supply was the profit margin. If you charge to high the customers rather buy a new unit with one year warranty given. If you charge too low, you may end up in the losing side because of the components replaced, electricity and etc. If you charge reasonable, the profit margin gained can't even cover your time spent on troubleshooting it. I'm here not to discourage you to stop repairing ATX power supply, however if you have the time, have contacts getting cheap power supply components, easy to access many power supply schematic diagrams and etc then you may go ahead to repair it.
Okay back to the article, one of my customers had asked me to repair his ATX power supply. I told him to get a new one (since it was very cheap) but he said he couldn't find one that suits his customer's CPU. He wanted a power supply that is either same size or smaller then the original one with same or higher specification but all he could find was a standard size power supply!
As a favors to my customer, I would do my best to help him to repair the ATX power supply. When the power supply was switch on, measurements were taken. The results were over voltage. The 12 volts line shot up to 13 + volt and the 5 volts line became 5.6 volts. After the casing was removed, I found the inside was very dirty and I used a vacuum cleaner and a brush to clean off the dirt. Then I saw four filter electrolytic capacitors had bulged at the top casing.
As you know, we as electronic repairers can't just see things at only one side; we have to see the other sides too. What I mean was, try to see if there are any suspicious components that contributed to the failure of the power supply such as broken components, dry joints, loose connection, decay glue and etc before start checking the suspected area.
What I saw was at the primary side there were some components covered with decayed glue as seen in the picture. I have to carefully remove it by scrapping off the layers of the decayed glue while preserving the outer layers of the components. Once it was done, I clean it with the Thinner solution. Decayed glue could cause serious or intermittent problem in electronic equipment because it can be conductive.
If you repair any ATX power supply, make sure you check the fan too because some power supply failure was due to heat caused by a faulty fan. The purpose of the fan is to suck out all the heat generated by the components inside the power supply. In order for the fan to run smooth, you can service it by using a Philips oil base spray as shown in the photo.
Once the four electrolytic capacitors were replaced and the decayed glue removed, I then have to plug it into a junk motherboard together with a hard disk to test the performance of the ATX power supply and measure all of its output voltages. It seems like the output voltages were back to normal. Once everything is okay I then test it in a working CPU to check for the display.
The reason I test it with a junk motherboard first as a way not to cause my good motherboard to go bad just in case if the output voltages is still very high. Better safe than regret later. By the way you can't test a power supply without load otherwise it may turned on for a while and then shut down. If you do not have a junk motherboard you can always at least connect a hard drive and a wire jumper to its connector to turn on the ATX power supply.
Do you know that most ATX power supply is using dual schottky barrier rectifiers to convert the ac wave into DC voltages? Even in LCD Monitor power supply, a dual schottky were used in the rectification too. For your information, checking schottky diode is different from checking a normal diode. With analog meter set to X10 K ohms, it should show some leakage reading when doing the reverse bias test. If this component becomes faulty it is very easy to get a replacement, of course you have to get one with the right specification. That's all for today, hope you enjoy the article and come back more often to check out for any latest repair techniques that I'm going to share to you.

Jet-Set Extravagance Courtesy Lamborghini Reventon
Few car makers (if any) have the reputation of Lamborghini. Since the early sixties, Lamborghini has produced exotic vehicles that inspire drool and envy - including the Miura, the Countach (which helped popularize sharp-angled sports cars) and the Diablo. And, yet, the latest Lamborghini model still manages to top its maker's reputation.
With a sleek, dark-gray (or "matte gray" as it is called) exterior, gazing at the Lamborghini Reventón is like staring into the future. Everything about the vehicle screams cool. That statement can be taken both figuratively or literally since the Reventón includes a number of unique external features designed to keep components from overheating at high speeds. Extraction fans positioned below its rear LED brake lights pull hot air from the engine, and opaque fins attached to the aluminum rims help cool the ceramic brake rotors. Other than the roof and doors (which are constructed of steel), all the body panels (and even the rim fins) are made of a carbon-fiber composite. The interior of the vehicle is no less impressive, with comfortable suede and shiny carbon fiber everywhere. But that's not the interior's most impressive component - that would be the dashboard display. Featuring three LCD screens, the driver can choose among various modes for the gauges - including a jet mode with a G-force meter.
If the jet connection seems appropriate, it goes deeper - the Reventón was intentionally designed with a jet feel in mind. Inspired by the stealth F-22 Raptor, one of the world's most effective fighter planes, Lamborghini's director of brand and design, Manfred Fitzgerald had each of his designers create a vision for the Reventón based on the jet. Fitzgerald then chose the design he liked best and sent the team to work refining it. Still, despite all the bells and whistles on the design end, in terms of performance, the Reventón actually doesn't do much more than the Lamborghini Murciélago LP640. Like the Murciélago, the Reventón has a V-12 engine, is controlled via a six-speed manual transmission and tops out at a similar speed of 211 mph. While the Reventón has a slight edge over the Murciélago in horsepower (650 instead of 640), the Murciélago has a slightly quicker pick up time (0 to 62 mph in 3.3 seconds compared to the Reventón's 3.4 seconds).
Certainly, though, no one will confuse the tag on the Reventón with the Murciélago's $300,000 ballpark price. The limited-edition piece of automotive artwork costs nearly $1.4 million (or 1 million euros). And don't get your hopes up, millionaires - only 21 Reventóns will be built and all of them have already been sold (with the exception of one car which will be stowed away in the Lamborghini vault). So, if not to make money (the costs of producing the vehicles doesn't leave room for much profit), what's the point? More than anything, the Reventón is a reassertion of Lamborghini's high-end position in the car industry. While it may not necessarily be practical to produce a wildly expensive car simply for visual appeal in a world of economic woes and debilitating gas prices, there is something to be said for the awe of excess. And nobody does awe or excess quite like Lamborghini.
