Spectrum Analyzer & Field Strength Analyzer

Spectrum Analyzer
An instrument which displays the frequency spectrum of an input signal, usually amplitude vertical vs. frequency horizontal.

Field Strength Analyzer
Practical field-strength measurements call for an analyzer that is portable yet powerful. The model 3290 RF Field Strength Analyzer from PROTEK Test and Measurement (Allendale, NJ) is a handheld instrument that contains not only a full-featured spectrum analyzer capable of measurements from 100 kHz to 2.9 GHz, but also a sensitive frequency counter, a host of demodulators, and the choice of operating on batteries, AC, or vehicle DC power.

Download PSpice 9.1 Student Version

PSPICE is a computer program used to perform simulations of electronic circuits. The Student Version of PSpice is intended for use by college students and professors who are interested in learning about analog and mixed-signal simulation. Limitations of this student version are a maximum of 64 nodes, 10 transistors, 65 digital primitive devices, and the sample library is limited to 39 analog and 134 digital parts.

# What is SPICE and what is PSpice?

SPICE is an analog (originally) circuit simulator that was developed at the University of California at Berkeley. PSpice is one of the many commercial SPICE derivatives, and has been developed by MicroSim Corporation.

# What does SPICE stand for?

SPICE stands for Simulation Program with Integrated Circuit Emphasis.

# How does PSpice help in circuit design?

PSpice's strong point is that it helps the user simulate the circuit design graphically on the computer before building a physical circuit. Hence, the designer can make any necessary changes on the prototype without modifying any hardware. As soon as the test design is completed, PSpice can help you run a check on it before deciding to commit yourself to building a hardware model. Hence, PSpiec allows you to check the operability of the circuit model in real life simulations to validate its viability. Since all the tests, designs and modifications are made over a terminal, the designer can save a lot of money that would have otherwise been spent on the building of models and modifying them.

4th game - Racer (14,921 KB)

There are 7 different tracks to race on, some of these are night time races and some day time. Racer contains loads of different cars to choose from. Just a few of these include the Ford Focus, Dodge Viper, Renault Megane, BMW Z3, Audi A6, Audi TT and many more.

Like all these types of games it can be hard in the beginning because you can only afford the cheapest cars and all the other players have better ones, but if you race well, soon you will be driving something like the Dodge Viper or Audi TT.

One nice feature is the training option which lets you race any of the cars so you can atleast try out the faster ones if you never manage to get there in Career mode.

Third Game - Little Fighter 2 (12,372 KB)

Little Fighter 2 is multi player with up to 4 players at a time. Not to worry if you don't have people to play with, one area Little Fighter 2 excels in that many other freeware games fall short is AI. The computer players are very challenging.

The makers of the game (Marti Wong & Starsky Wong) are continually updating the game and adding new characters so it will never get boring.

Second game - Silver Knights (4180 KB)

Silver Knights is a fun 3D mech game that is too good to be ignored. It is a Japanese game, though the language in the game is English. Right now, there is only a Battle Mode, where you can play three different game types. There is a story mode planned, as well, but don't expect it to surface for a few months. The game gets updated every now and then, so check back to the website every couple of weeks for updates.

The graphics in Silver Knights are wonderful. The mechs look cool and are done in Japanese style. The game is all in 3D and the special effects and explosions look great. It looks and plays like a newer PS1 game, which is quite a feat for a freeware game. There's never a hint of slowdown, but I found the camera angle to be slightly annoying. It jerks around a bit too much for my liking. The many levels in Silver Knights are done beautifully, and each plays very well. Though some levels were a bit boring in previous versions of SK, the levels in the latest version are all very enjoyable.
The controls in the game are a bit aggravating, but can be changed in the options menu. Still, locking onto an enemy remains a bit frustrating. On the other hand, the gameplay is simply excellent. You choose one of several mechs, decide which team you'll be on, and battle it out in one of a dozen arenas. You have 3 projectile attacks, and many hand-to-hand combos are possible, as well. All of the characters are fairly balanced, and each one has different attacks and capabilities. You can adjust the AI to be as easy or difficult as you want, which adds loads of time to the replay value. Not to mention, with a separate program (downloadable at the author's site), you can give the robots emblems. You can also edit their paint jobs with the main executable.

The music is jazzy and upbeat, and very pleasing to the ears. There are at least five tracks, too, so the music you'll hear while playing SK won't still be in your head throughout the day. It beats the single track of boring piano music of past versions by a mile. The sound is also pretty good, but isn't particularly amazing. Sounds of boosts and gunshots from your mech can be heard, but the clanks and whirrs heard in some other mech games (e.g. Bachan-On) aren't to be found.

Overall, Silver Knights is one of the the best freeware mech games found on the internet. As of now, I'd say it's THE best. No doubt about it. It's still progressing nicely, too.

First game -- MindArms (9232 KB)

MindArms is a great 2D fighter, one of the best freeware fighting games coz it got smooth character animations, a gameplay style that anyone can grasp after only a few minutes of play, and catchy music. What more do you need? A more in-depth review? Ok...read on!

MindArms' gameplay is fast, fun, and easy to learn. Unlike the complicated button presses used for special moves in games like Street Fighter, MindArms' special attacks are executed by pressing only a couple of keys in order. But don't think that you can just perform one attack over and over again to win; the AI is fairly aggressive compared to what is found in other freeware fighters, even if it won't offer a great challenge. MindArms has only five characters available from the start, but each is very unique (most fighting games like to use variations of the same character and give them different names), though the small roster of fighters may annoy some. It must also be noted that the game uses a distinctly Japanese style. I think that three of the characters are guys and the other two are girls, but I wouldn't be surprised if I was wrong. You won't find any big, muscular guys in this game, just girly men. MindArms' graphics are very good, and could compete with most 2D commercial fighting games on the market today. Also, the character animations are very fluid, and could easily beat most 2D commercial fighting games. Without a doubt, MindArms is real eye candy. MindArms' sound is the average stuff you would find in any other fighting game, and the music is slightly above average. The game's got some catchy tunes, but none that really stand out. Needless to say, you won't be annoyed by MindArms' sound and music, but you won't be amazed, either.

Overall, MindArms is a great fighting game, one of the best fighting games you can download for free. If you don't think you'll be annoyed by the Japanese style or small roster of fighters, MindArms is worth the download.

WiMAX and the last mile potential for wireless broadband

Internet and intranet users need broadband access that extends over longer distances to more locations. The industry's solution is the Worldwide Interoperability for Microwave Access (WiMAX) standard, developed to create certified standards-based products from a wide range of vendors.

The WiMAX standard enables system vendors to create many different types of WiMAX-based products, including various configurations of base stations and customer premise equipment (CPE). WiMAX supports a variety of wireless broadband connections: * High-bandwidth metropolitan-area networks (MANs) to home and small-business users, replacing DSL and cable modems; * Backhaul networks for cellular base stations, bypassing the public switched telephone network; * Backhaul connections to the Internet for WiFi hotspots. Where they exist today, these applications use expensive proprietary methods for broadband wireless access. This expense can be dramatically reduced by using interoperability-tested WiMAX silicon solutions based on the IEEE 802.16d standard. Leaders in semiconductor technology, such as Fujitsu Microelectronics America, Inc., will deliver the expanded broadband wireless capability by working in close partnership with infrastructure and equipment manufacturers.

Like WiFi (IEEE 802.11) before it, WiMAX promises explosive growth. The key to taking advantage of WiMAX opportunities is to understand the technology's evolution and anticipated deployment.

FCC lets startup deploy 4.9 GHz mobile mesh nets

The Federal Communication Commission has granted startup MeshNetworks an experimental license to deploy a number of fixed and mobile mesh networks in the 4.9 GHz band.

MeshNetworks has been working on a wireless mesh networking solution that couples radio technology with routing capabilities. At the heart of MeshNetworks solution is a Layer 2 protocol that relies on such metrics as received signal strength, error rates, and data rates to derive the optimum route within a network. The FCC grant allows MeshNetworks to deploy a total of 1000 nodes, with a maximum of 200 per demonstration network. Each node is licensed to operate with a maximum effective radiated power (ERP) of up 16 W.

Gallium arsenide (GaAs) IC market worth 2.9 billion in 2004

The worldwide GaAs device market will grow from $2.7 billion in 2003 to $2.9 billion in 2004 and reach $3.7 billion in 2008. Strategy Analytics, which had previously described the digital GaAs market as dead, is forecasting a compound average growth rate of 7 percent for the 2003 to 2008 timeframe for the overall GaAs market. While volume demand for bulk and epitaxial GaAs substrates will increase, the total market for GaAs substrates, bulk and epitaxial, would only grow at a CAGR of 7 percent from $387 million in 2003 to reach $541 million in 2008.

Overall market growth for GaAs devices will continue to be dependent primarily on the wireless markets, with the cellular handset market being the primary driver. Demand from other applications, such as automotive radar, will increase, but cellular handsets will still account for at least 33 percent of the GaAs device market in 2008.

Voice over Internet Protocol (VoIP)

What is VoIP/Internet Voice?
VoIP allows you to make telephone calls using a computer network, over a data network like the Internet. VoIP converts the voice signal from your telephone into a digital signal that travels over the internet then converts it back at the other end so you can speak to anyone with a regular phone number. When placing a VoIP call using a phone with an adapter, you'll hear a dial tone and dial just as you always have. VoIP may also allow you to make a call directly from a computer using a conventional telephone or a microphone.

How Can I Place a VoIP Call?
Depending on the service, one way to place a VoIP call is to pick up your phone and dial the number, using an adaptor that connects to your existing high-speed Internet connection. The call goes through your local telephone company to a VoIP provider. The phone call goes over the Internet to the called party's local telephone company for the completion of the call. Another way is to utilize a microphone headset plugged into your computer. The number is placed using the keyboard and is routed through your cable modem.

What Kind of Equipment Do I Need?
A broadband (high speed Internet) connection is required. This can be through a cable modem, or high speed services such as DSL or a local area network. You can hook up an inexpensive microphone to your computer and send your voice through a cable modem or connect a phone directly to a telephone adaptor.

Is there a difference between making a Local Call and a Long Distance Call?

Some VoIP providers offer their services for free, normally only for calls to other subscribers to the service. Your VoIP provider may permit you to select an area code different from the area in which you live. This means you may not incur long distance charges if you call a number in your area code regardless of geography. It also means that people who call you may incur long distance charges depending on their area code and service.

Some VoIP providers charge for a long distance call to a number outside your calling area, similar to existing, traditional wireline telephone service. Other VoIP providers permit you to call anywhere at a flat rate for a fixed number of minutes.

If I have Internet Voice service, who can I call?
Depending upon your service, you might be limited only to other subscribers to the service, or you may be able to call any phone number, anywhere in the world. The call can be made to a local number, a mobile phone, to a long distance number, or an international number. You may even utilize the service to speak with more than one person at a time. The person you are calling does not need any special equipment, just a phone.

What Are Some Advantages of Internet Voice?
Because Internet Voice is digital, it may offer features and services that are not available with a traditional phone. If you have a broadband internet connection, you need not maintain and pay the additional cost for a line just to make telephone calls.

With many Internet Voice plans you can talk for as long as you want with any person in the world (the requirement is that the other person has an Internet connection). You can also talk with many people at the same time without any additional cost.

Free Digital Camera Enhancer

Thanks, CHarneyCHRIS for suggesting this freeware!

Already upload to http://www.geocities.com/mmusoft/index.html
The old page still there, waiting for the new page to refresh.

The program works best if you have bad light condition (indoor, shadows etc..) and your image is somehow off. So if some of your images are already fine, you won't see much difference. One thing makes DCEnhancer different from other tools - reducing the noise and skin smoothing algorithm. It makes DCE ideal for making cool portraits and close-ups! More

Viral movies possible with RealPlayer flaw

A software slipup in RealNetworks' music player means that Windows, Mac and Linux computers could be compromised by a fake movie file, a security company said Friday.

The problem means that fake movie files could be created that, when played by vulnerable Real software, would run a program instead. The flaw appears in RealPlayer 10 for Windows and Mac OS X, the RealOne Player for Windows and Mac OS X and the Real Helix Player for Linux. Read more
