Fortron Source power supply review

2008-06-27T20:26:00.000-07:00

In the last couple of years, the PC market has changed from being almost 100% performance focussed, to becoming very noise conscious. While delta fans running at 7000rpms were accepted a few years ago, even fans running at 3000rpms are considered noisy today. This combined with the rapidly rising power requirements from today’s high-end components, the performance, cooling and noise of power supplies have become a central issue in an enthusiasts’ buying decision.

1200w PSU review

2008-06-27T20:19:00.000-07:00

Tuniq is the performance oriented division of Sunbeam Technology. Their coolers, cases, power supplies and accessories are designed for more of the niche audience who demand a higher level of performance from their gear. Tuniq's line of power supplies displays this thinking with high wattage and high efficiency units. A quick example of this is the smallest PSU Tuniq makes is 950 watts.

I like it but can not buy.

Fixed Wireless, WiMax, and WiFi Market Opportunities, Strategies, and Forecasts, 2005 to 2010

2008-03-17T01:51:00.000-07:00

Consumer broadband adoption is accompanied by purchases of access points and adaptors. Wi-Fi adoption has been slower in the enterprise sector. Prices for consumer equipment have been falling faster than those for enterprise-grade systems. SOHO and consumer spending has outpaced that of enterprises.A big factor preventing greater Wi-Fi adoption in enterprise organizations has been lack of security. 802.11i is the protocol intended to ensure Wi-Fi network security. It gives organizations a much greater level of comfort with the technology.Hot spot subscriber penetration of wireless subscriber markets does not detract from wireless subscribers using voice telephones that are possible to use while roaming and hot spot Internet access for data while traveling away from the home or office.

Buffalo Hi Gain USB WiFi Antenna with 1600 ft Range

2007-10-28T07:27:00.000-07:00

Buffalo Technology announced today the release of two use Wireless-G High Gain USB 2.0 adapters, the WLI-U2-SG54HG and WLI-U2-G54HG. The SG54HG uses an omni-directional antenna for optimal connection and range and attaches to the notebook or desktop with suction cups to keep it secured out of the way. The G54HG uses a directional antenna as well with the addition of a signal strength indicator to allow you to tune for ideal performance. The G54HG measures in at 2.8" x 3.5" and weighs 0.2 pounds so it won’t add significantly to the weight of your notebook. The really fantastic feature of both of these products is Buffalo’s claim that they offer Wireless-G connectivity with a range of 1600 feet. Both adapters are fully USB powered and require no external adapters. Availability on both models is set for May at a price of $49. These new products are souped up versions of the SGH54HP from a while back.

2007-10-28T07:24:00.000-07:00

Increasing of the radiation power on the device side isn’t legal and might be a subject only for the qualified electrical engineers. So the normal practice is to redistribute power in the volume. Thus many WiFi devices have an option to exchange their antennas. Than you can replace the original omni-directional antenna by a directional antenna. The power and sensitivity can be increased in a desired direction. The antenna of Linksys 802.11G RANGE EXTENDER - WRE54G can not be replaced for now.

Hi-Gain Antenna Technology Extends Wireless Range
Hawking Technologies' HWC54D Wireless-G Cardbus PC Card Adapter features the latest in wireless technology. Standard wireless cardbus cards use low power antennas that deliver a circular signal pattern. This type of pattern recieves interference from the metal components within the laptop resulting in a drop in wireless performance and distance. The HWC54D solves this problem with its advanced directional 6 dBi Hi-Gain Antenna that delivers a strong concentrated signal in the direction of the wireless access point to establish a strong wireless link resulting in a significant increase in operating distance (Up to 200%). The Hi-Gain antenna position swivels and folds to make finding an optimal signal easy and simple. When you are not using the card, simply fold the antenna down for compact, safe, easy transport.

2007-07-06T12:01:00.001-07:00

Parts List:
 R1 = 10K
 R2 = 100K
 R3 = 100 ohm
 R4 = 50K potmeter, Linear
C1,C2 = 0.1uF
 C3 = 0.01uF
 C4 = 2700uF
 Q1 = TIP41A, NPN, or equivalent
 Q2 = TIP42A, PNP, or equivalent
 L1 = 1uH
 T1 = Filament transformer, your choice

This DC-to-AC inverter schematic produces an AC output at line frequency and voltage. The 555 is configured as a low-frequency oscillator, tunable over the frequency range of 50 to 60 Hz by Frequency potentiometer R4.
The 555 feeds its output (amplified by Q1 and Q2) to the input of transformer T1, a reverse-connected filament transformer with the necessary step-up turns ratio. Capacitor C4 and coil L1 filter the input to T1, assuring that it is effectively a sine wave. Adjust the value of T1 to your voltage.

The output (in watts) is up to you by selecting different components.

Input voltage is anywhere from +5V to +15Volt DC, adjust the 2700uF cap's working voltage accordingly.
Replacement types for Q1 are: TIP41B, TIP41C, NTE196, ECG196, etc. Replacement types for Q2 are: TIP42B, TIP42C, NTE197, ECG197, etc. Don't be afraid to use another type of similar specs, it's only a transistor... ;-)

If the whole thing is working, good. If not, relax and don't get frustrated. Do the following checks:
1) You have connected the filament transformer in REVERSE yes?
2) If not, disconnect the power and reverse. If you have, disconnect the transformer and measure the voltage after L1 and ground.
3) Just in case, GROUND for this circuit is same as negative (-).
4) Q1/Q2 are oposites, e.i. npn/pnp.
5) Is your 555 perhaps defective? Disconnect R3 from pin 3 and check pin 3 for a pulse.
6) Check your transistors to make sure they are not defective.

DC - To - AC Conversion

2007-07-06T11:52:00.000-07:00

The converter that changes a dc voltage to an alternating voltage is called an inverter. Earlier inverters were built with SCRs. Since the circuitry required to turn the SCR off tends to be complex, other power semiconductor devices such as bipolar junction transistors, power MOSFETs, insulated gate bipolar transistors (IGBT) and MOS-controlled thyristors (MCTs) are used nowadays. Currently only the inverters with a high power rating, such as 500 kW or higher, are likely to be built with either SCRs or gate turn-off thyristors(GTOs). There are many inverter circuits and the techniques for controlling an inverter vary in complexity.
Some of the applications of an inverter are listed below:

Emergency lighting systems,
AC variable speed drives,
Uninterrupted power supplies, and
Frequency converters.

Setting Up Your Laptop

2007-07-04T23:50:00.000-07:00

Features vary from laptop to laptop: Not every laptop has the same keyboard layout; the CD-ROM or DVD drive may eject forward, to the left, to the right, or may not even exist; connectors and holes may be on the sides, back, or both; and the power button? Well, it could be anywhere!

Beyond the differences, if you squint your eyes tight enough, all laptop computers look basically the same. Each laptop has a similar setup, so this article addresses issues that all laptop owners have to deal with.

If you find any specific instructions regarding setup inside the laptop box or - should you be so lucky - if you find a manual, heed its instructions first.
Do you need to charge the battery?

When setting up your laptop, the holiest piece of hardware is the battery. Om! It either came preinstalled (and perhaps even non-removable) inside the laptop, or it came separately and you have to install it.

Install or set up the battery. Fortunately, this is one of those things where you can find the instructions included with the laptop. The instructions may tell you how to install the battery, which doodad to remove to make the battery work, or other important battery preparations.

Keep these battery-related points in mind when dealing with your laptop:

* You can use your laptop without the battery, but you probably want to properly set up the battery just to make sure that it works.

* Some batteries come DOA - you have to charge them before you can use them. You normally charge a battery by installing it inside the laptop, then plugging the laptop's power brick both into the wall and into the laptop. Battery charging takes place automatically.

* Charging a laptop's battery usually takes a few hours. The exact time that you need depends on the type of battery, power management hardware, and whether or not you're using the laptop at the time.

* If the battery comes already charged, then simply install it, and you're ready to go! Literally!

* The manufacturer may claim that the battery is fully charged, but don't be surprised if it isn't. No big deal; just install the battery and plug in the laptop. It will charge.

* You can let your laptop's batteries charge overnight.

* Be sure to put any extra or spare batteries in storage when you're not using them.

Is some assembly required?

Beyond that battery, you may have to add some features to your laptop. Pray that such a thing doesn't happen to you! But some laptops have arrived without memory, disk drives, and other options installed. If your laptop isn't ready to go when you get it, you have to properly install the missing items. Best of luck!

Most laptops come fully assembled. In fact, many laptops don't let you install extra features.

Fortunately, if you do have to install some options, you install options such as memory or a network adapter only once. Follow the directions closely. Read them over first before attempting the installation. In most cases, you can get the options installed smoothly. It also helps that you can insert most components in only one direction, so you can't goof things up too badly.

Beware of Electrostatic Discharge (ESD). That tiny little spark that you generate on a dry day can permanently damage your laptop. When installing options, always keep one hand touching the laptop's case. This precaution helps lessen the potential of the dreaded ESD.

If your laptop came with a docking station or port replicator, don't worry about setting up this add-on or using it just yet. The laptop works fine without that optional feature, so you may want to use the laptop for a while before you mount the docking station or port replicator.

How to Buy Headphones

2007-06-03T09:11:00.001-07:00

Buying advice on headphones is a lot like relationship advice—there are no hard and fast rules; everything depends on your individual needs and personal preferences.

The major buying considerations for headphones are form factor, acoustics and price. And they are all intertwined: the form factor affects the acoustics, which affects the price.

In the Ear Headphones
Headphones come in two basic forms: in the ear and over the ear.

For in the ear headphones, we are talking about round ear buds that wedge into your ear canal, vertical in-ear headsets that are supported by a headband over the top of your head and rest in the ear canal, or earplug type headphones that can be customized to fit your ear canal.

It's Very Subjective
We're talking about shoving a piece of plastic into your ear canal. It's incredibly personal. Some sets of in-ear headphones will fit like a glove, others will be unspeakably painful. Round earbuds and vertical headsets are relatively inexpensive: $12-15 for the low end, so you can probably afford to try a pair. The earplug varieties from manufacturers like Shure and Etymotic can top $300, so go to a retailer who can offer you a trial fitting. At the most recent MacWorld in San Francisco, the Etymotic booth staff were using disposable covers on the earplugs to allow users a trial and fitting session. Try before you buy.

Over the Ear Headphones
Over the ear headphones come in two basic forms: open and closed. Sports-style open headphones rest on the outside of the ears and are supported by an over the head or behind the neck band. Personally, I prefer to exercise with the behind the neck headphones. They move less and the open design allows for more air and ambient noise to come through. I don't like my ears getting hot, and I like to be able to hear cars and peripheral noises around me when I am running. Prices on these headphones start at $15.

Closed or Open Over the Ear Headphones
Cupped open headphones provide less sound isolation, allowing for more ambient noise. But some people feel open headphones sound more natural than their closed or noise-reducing counterparts. The open backs on these headphones reduce the low-resonance effect that closed headphones can sometimes produce.

Closed headphones provide more isolation from ambient sounds, but can overly resonate low frequencies. If I had to recommend one pair of mid-range headphones that would be categorized as closed over the ear cushioned headphones: I would suggest the Sony MDR7506 headphones. These are an industry standard for television and audio professionals. They are comfortable and very durable.

New Technologies
Noise canceling headphones are great for plane trips: they actively eliminate much of the engine noise that travelers have to endure. I also use mine for weed-whacking: any consistent sound can be partially mitigated with noise canceling headphones. But this technology does not do much to block out intermittent noise like conversations and crying babies. Bottomline: if you travel a lot, noise canceling headphones are worth the extra expense.

Wireless stereo headphones are being marketed using Bluetooth technology. A Bluetooth transmitter plugs into your MP3 player or audio jack, and the headphones receive a wireless transmission of the output. So far, reviews have been mixed on this technology for stereo headphone use. Audio quality and signal stability have been questioned, but if you must go hands-free, Bluetooth is an option.

Feel the iLuv with These Bluetooth Headphones

2007-06-03T09:07:00.000-07:00

You may remember my suggestion to cut the cord with wireless headphones. I recommended three Bluetooth headphones, including the Etymotic ety8 rectangular earpieces, and the Logitech FreePulse Wireless headphones, both great options for iPod users. iLuv has now introduced two more alternatives I simply must add to this list. Their latest releases include the i202 Bluetooth Ear Clips and i903 Noise-Canceling Bluetooth headphones.

I'm not a fan of the DJ style headphones because of their bulkiness, but office workers will appreciate being able to listen to their MP3 players and mobiles all with one device. Of course, this only works if you have a Bluetooth-enabled phone, which will come in handy when you need to answer or make outgoing calls. To use your iPod, you'll need to plug in the included Bluetooth audio adapter. I'm much more interested in how the i202 ear clip headphones (pictured here) work. They look fantastic, but I wonder how they stay on if you're out jogging. Both are great options that keep your gadgets safely in your purse.

Motorola's S9 Headphones for iPod/Phones

2007-06-03T09:02:00.000-07:00

Bluetooth headphones are such a great idea, but I haven't seen any that are light enough to take to the gym until now. I came across Motorola's S9 Bluetooth headphones at CES, and was surprised by how good they sound. These behind-the-ear active headphones are water-resistant and include integrated touch controls that allow you to navigate through your music, as well as answer calls wirelessly.

And they also work with your iPod if you purchase a Bluetooth adapter that attaches to the bottom of your player, much like the one used for the Nike Plus Sports kit. You won't like these headphones if you don't like earbuds, and I can see how they can be irritating to wear while running. The black or red rubberized headphones are very sleek, though, and probably the lightest Bluetooth headphones I've seen. The S9 Motorola Bluetooth Active Headphones will be available in the first half of 2007.

LCR meter

2007-03-10T23:44:00.001-08:00

This is the measuring device called a LCR meter. This device can mesure the value of coil(L), capacitor(C) and resistor(R) each.

Measurement range is shown below ( incase of right photograph )

Coil	:	1 µH	to	200 H
Capacitor	:	0.1 pF	to	200 µF
Resistor	:	0.01 ohm	to	20 M-ohm

The photograph of the right is measuring the coil of 56 micro H(µH) with the 2 mH range. It is displayed as 53 µH.

This is convenient for circuit making.

Circuit tester

2007-03-10T23:43:00.001-08:00

Circuit tester
Circuit tester can measure various electric values. Such as the measurement of the resistor value, the measurement of the voltage, the measurement of the current, the confirmation of the polarity of the light emitting diode etc. This tool is necessary for electronic circuit making.

The circuit teser shown on photograph is an analog type, the measurement result is confirmed with the needle that calls the meter. Besides there is a digital type, the measurement result is confirmed with the digital display. Digital type can easily confirm the result. Even the analog type is able to use sufficiently. I am using and like the analog type.

Fundamentally following items can measure by the circuit tester.

DC voltage
AC voltage
DC current
Resistance value

Some circuit tester can measure the value of capacitor, the value of coil, the characteristic of transistor etc.

Digital Multimeter

2007-03-10T23:42:00.000-08:00

Digital Multimeter

This is the measurement receptacle which displays the voltage, the electric current, the other measurement result in the digital. The display is easy to see compared with the analog-type circuit tester and the contents which can be measured are very rich. The digital type always needs the battery but in case of the analog-type circuit tester, it is possible to measure without the battery except the measurement of the resistance. Recently, the digital type is oftener used. I am using the analog type mainly. The wire which is connected with the left yellow connector of the tester is the probe of the thermocouple thermometry. The tip of the wire has the thermocouple temperature sensor.

The one of the photograph chooses the measurement item with the switch in the 32 positions. Following measurement is possible.

Appearance of the Transistor

2007-02-03T10:32:00.002-08:00

The outward appearance of the transistor varies. Here, two kinds are shown.

On the left in the photograph is a 2SC1815 transistor, which is good for use in a digital circuit. They are inexpensive when I buy them in quantity. In Japan it costs 2,000 yen for a pack of 200 pieces. (About 10 US cents/piece in 1998)

On the right is a device which is used when a large current is to be handled. Its part number is 2SD880.

The electrical characteristics of each is as follows.

Item	2SC1815	2SD880
V_CEO(V)	50	60
I_C(mA)	150	3A
P_C(mW)	400	30W
h_FE	70 - 700	60 - 300
f_T(MHz)	80	3

V_CEO	:	The maximum voltage that can be handled across the collector(C) and emitter(E) when the base(B) is open. (Not connected) (It may be shown as V_CE)
I_C	:	The maximum collector(C) current.
P_C	:	Maximum collector(C) loss that continuously can cause it consumed at surroundings temperature (Ta)=25°C (no radiator)
h_FE	:	The current gain to DC at the emitter(E). (I_C/I_B)
f_T	:	The maximum DC switching frequency. (the transision frequency)

Data sheet for 2SC1815

Transistors

2007-02-03T10:32:00.001-08:00

The transistor's finction is to amplify an electric current.
Many different kinds of transistors are used in analog circuits, for different reasons. This is not the case for digital circuits. In a digital circuit, only two values matter; on or off. The amplification abilitiy of a transistor is not relevant in a digital circuit. In many cases, a circuit is built with integrated circuits(ICs).
Transistors are often used in digital circuits as buffers to protect ICs. For example, when powering an electromagnetic switch (called a 'relay'), or when controlling a light emitting diode. (In my case.)

Two different symbols are used for the transistor.

PNP type and NPN type

The name (standard part number) of the transistor, as well as the type and the way it is used is shown below.

2SAXXXX PNP type high frequency

2SBXXXX PNP type low frequency

2SCXXXX NPN type high frequency

2SDXXXX NPN type low frequency

The direction of the current flow differs between the PNP and NPN type.
When the power supply is the side of the positive (plus), the NPN type is easy to use.

Shottky barrier diode

2007-02-03T10:31:00.001-08:00

Diodes are used to rectify alternating current into direct current. However, rectification will not occur when the frequency of the alternating current is too high. This is due to what is known as the "reverse recovery characteristic."
The reverse recovery characteristic can be explained as follows:
IF the opposite voltage is suddenly applied to a forward-biased diode, current will continue to flow in the forward direction for a brief moment. This time until the current stops flowing is called the Reverse Recovery Time. The current is considered to be stopped when it falls to about 10% of the value of the peak reverse current.
The Shottky barrier diode has a short reverse recovery time, which makes it ideally suited to use in high frequency rectification.

The shottky barrier diode has the following characteristics.

The voltage drop in the forward direction is low.

The reverse recovery time is short.

However, it has the following disadvantages.

The diode can have relatively high leakage current.

The surge resistance is low.

Because the reverse recovery time is short, this diode is often used for the switching regulator in a high frequency circuit.

Light Emitting Diode ( LED )

2007-02-03T10:26:00.000-08:00

Light emitting diodes must be choosen according to how they will be used, because there are various kinds.
The diodes are available in several colors. The most common colors are red and green, but there are even blue ones.

The device on the far right in the photograph combines a red LED and green LED in one package. The component lead in the middle is common to both LEDs. As for the remaing two leads, one side is for the green, the other for the red LED. When both are turned on simultaneously, it becomes orange.

When an LED is new out of the package, the polarity of the device can be determined by looking at the leads. The longer lead is the Anode side, and the short one is the Cathode side.

The polarity of an LED can also be determined using a resistance meter, or even a 1.5 V battery.

When using a test meter to determine polarity, set the meter to a low resistance measurement range. Connect the probes of the meter to the LED. If the polarity is correct, the LED will glow. If the LED does not glow, switch the meter probes to the opposite leads on the LED. In either case, the side of the diode which is connected to the black meter probe when the LED glows, is the Anode side. Positive voltage flows out of the black probe when the meter is set to measure resistance.

It is possible to use an LED to obtain a fixed voltage.
The voltage drop (forward voltage, or V_F) of an LED is comparatively stable at just about 2V.

Diode bridge

2007-02-03T10:25:00.000-08:00

Rectification diodes are used to make DC from AC. It is possible to do only 'half wave rectification' using 1 diode. When 4 diodes are combined, 'full wave rectification' occurrs.
Devices that combine 4 diodes in one package are called diode bridges. They are used for full-wave rectification.

The photograph on the left shows two examples of diode bridges.

The cylindrical device on the right in the photograph has a current limit of 1A. Physically, it is 7 mm high, and 10 mm in diameter.
The flat device on the left has a current limit of 4A. It is has a thickness of 6 mm, is 16 mm in height, and 19 mm in width.

The photograph on the right shows a large, high-power diode bridge.
It has a current capacity of 15A. The peak reverse-bias voltage is 400V.
Diode bridges with large current capacities like this one, require a heat sink. Typically, they are screwed to a piece of metal, or the chasis of device in which they are used. The heat sink allows the device to radiate excess heat.
As for size, this one is 26 mm wide on each side, and the height of the module part is 10 mm.

Rectification / Switching / Regulation Diode

2007-02-03T10:24:00.000-08:00

The stripe stamped on one end of the diode shows indicates the polarity of the diode.
The stripe shows the cathode side.
The top two devices shown in the picture are diodes used for rectification. They are made to handle relatively high currents. The device on top can handle as high as 6A, and the one below it can safely handle up to 1A.
However, it is best used at about 70% of its rating because this current value is a maximum rating.
The third device from the top (red color) has a part number of 1S1588. This diode is used for switching, because it can switch on and off at very high speed. However, the maximum current it can handle is 120 mA. This makes it well suited to use within digital circuits. The maximum reverse voltage (reverse bias) this diode can handle is 30V.
The device at the bottom of the picture is a voltage regulation diode with a rating of 6V. When this type of diode is reverse biased, it will resist changes in voltage. If the input voltage is increased, the output voltage will not change. (Or any change will be an insignificant amount.) While the output voltage does not increase with an increase in input voltage, the output current will.
This requires some thought for a protection circuit so that too much current does not flow.
The rated current limit for the device is 30 mA.
Generally, a 3-terminal voltage regulator is used for the stabilization of a power supply. Therefore, this diode is typically used to protect the circuit from momentary voltage spikes. 3 terminal regulators use voltage regulation diodes inside.
