How Do You Fix the Picture on a 47" LG LED LCD TV?

Are you feeding it an HD signal? If the answer is "no" or "I do not know", then your problem is that you are feeding it a non HD signal. To receive HDTV, you need one of three things: an antenna, an HD cable TV signal, or an HD satellite dish & receiver. Shame on whoever sold you the TV, but neglected to educate you.

1. I have a LED/LCD TV with a crack in the glass. Can it be fixed?

call and ask first it almost cost as much to have fixed than it would be to replace

2. Which one on Sony led or lcd tv PS3?

1. Yes, Comes with both 1080P or 720P. Just check the stores on HDTV you want 2. Both are consider the same, 3. 26 inch LED should be better. but it's too small for gaming

3. Can I plug my seagate external hard drive into the usb port on LED or LCD tv ?

Read your TV manual to see if it has the software required to read a HDD. I doubt you will damage anything trying though.

4. What are the differences between a 32 in. flat screen LED and LCD tv? (And other ?s) Please read and help!?

what i can say is..........led is a new technology...brighter than lcd and has long life

5. Would receiver afftect quality of fast 240Hz LED/LCD TV?

Nothing you connect is going to affect the 240Hz. TV. and here's why. First of all no matter what the salesman or the manual tells you wont get the full effect of the 240hz refresh technology because nothing is broadcast at that rate yet. Your TV will emulate what it may be seeming like 240 but in reality it is only working as fast as current video is broadcast in and that is 60hz...Sorry, do not believe the hype. You wont even know what it will look like because the human eye would not be able to "register" any refresh that occurs that fast anyway. I could put a TV in front of you that refreshed at 60, another that supposedly refreshed at 120Hz and another at 240Hz and you would not know the difference between the 3. The others would appear a bit faster but that is the synthesized emulation that is being presented. Key word is emulate, but even that is not true. So... none of your other items would have any affect on the item, BTW, dId you know that it does not matter if your TV has if the contrast ratio is higher than 98,000:1 because, again the human eye cant possible tell the difference between that many color temperatures anyway.

6. My Samsung LED LCD TV has a green tint?

I strongly suspect that there is a defect in the television set, and possibly the set is in the process of failing completely. If the set is under warranty, have it repaired. If it is out of warranty, the size of the set will determine if it's worth repairing. Typically 32" and under are not worth repairing, but the larger sets are. In your case, you have a good brand of set - that is a plus for repair vs. replace

7. I want to buy an led lcd tv but it has no headphone jack. I also want sennheisser wireless headphones but how?

in case you have a stereo gadget, plug it to the white purple n yellow jacks. you've got the skill to apply its output jack for connecting the headphones. in any different case, you ought to purchase a phono to audio jack converter and u. s. it straight away. . the 1st technique is the applicable. . good good fortune.

8. led or lcd tv of below 20 inch size which brand is best.please reply?

we had allmost the same question and here is the answer i got the guy at future shop said that its not like the old days where tvs where one big piece now all brands are using the same parts so brand does not matter you can just go to the store pick up a tv that you like wether its the graphics or the price

9. I don't know which 3d tv I should get? A Samsung Plasma 3dtv or Samsung 3d LED-LCD tv? Help!!!?

LED-LCD gives a slightly better quality image than a plasma

Would Receiver Afftect Quality of Fast 240Hz LED/LCD TV?
nicely it does not truly count extensive type to me significant because of the fact i will purely get 4 channels so my viewing of RTV is constrained! There does look an undesirable lot of them presently although and of those i will view i am selective at what I watch. till now anybody says something a pair of Freeview field - they do no longer paintings in my section!!1. LG LED LCD TV 32" can't find any valid channel! Check your antenna connection and try again?"...now i removed it from the tv..." That's your problem. Your cable company has converted to all-digital channels, and you have removed your digital converter. You are trying to receive the old analog channels, and they are gone. That's evident from the "check antenna connection" message you get when you scan for channels. Most likely, you will need to upgrade your subscription with the cable company in order to receive more channels than is possible with the basic converter.2. Are LED and LCD tv's categorized under "plasma"? If they're not, then how are they related?Plasma TV utilizes electrical arcs in gas -- similar to flouresescent lamps. The pixels, individual color blocks in the image, are in fact a variety of flourescent lamp, but unlike these lamps can display different colors. Because of the array of tiny arcs, plasma is very bright but generally high power consumption (not energy efficient). LCD and LED also use tiny pixels of color, but instead use modern-day versions of the same display that you may wear on your wrist (watch face) or in your calculator3.

I have degrees in both electrical engineering and electronic engineering.lol I do not know if your question is theoretical or you are looking for advice on replacing bulbs in your car.Anyway, the current brightest possible bulbs go up to 5000u20135500lm with the help of upto 4 COB LED chips. Usually cree xhp 70.2 or philips zeus series. But that does not mean they are the best. Beam pattern and proper luminance at light points are far more important than raw lumens above 2000lm. Some of the best PNP LED bulbs that adhere to power ratings the light patterns of halogen equivalents range from 1800u20133600lm. Once again I cannot stress this enough! Beam pattern is more important than raw brightness!.As an engineer myself working in this field, upcoming advancements in LED technology allow us to achieve 2-3x the brightness at same power, so instead of 3600lm 35w we get 7200u201310,000lm 35w. But we reduce the wattage to make lights more power efficient while keeping the output to around 2000u20133000lm depending on the manufactureru2019s requirements. We are rather focusing on ADB and such smart features that are more helpful than raw brightness.What is the brightest possible LED headlight, with high/low beam, capacity? I can wire up, literally, any type of conversion. I have degrees in both electrical engineering and electronic engineeringFinding LED specsI use my formula Vf=Vt If*RsI use some low current for Vt like 10% of rated DC current at some known temp. for silicon, Vt=0.55 , for Red/Yellow UB , Vt= 1.7 to 1.8 , for BLue/White Vt =2.7 to 2.8V (low for high power diodes)2.8 If*Rs (/-50%)=Vf for low power devices or Vf=2.7 If * Rs =Vf /-10% for high powerwhere Rs internal anode and bulk resistance Rs=0.5/Pmax /-50% depending quality of LED and heatsink Tj= 85'C for If>10%So for your results 3.2=2.8 0.27A*Rs gives Rs= 1.5 Ohm or 2/3W. /- 50% or Vf=2.7If * Rs for If >=1A white LED Thus at 1A this LED is 2.71A * 0.5 Ohms = 3.2 V /- 10% which agrees with the datasheet 2.9 to 3.5V at some temp. The VI typ curve shows Vf drops 0.1V from 1000mA to 800mA thus 0.1/0.2=0.5ohm so Pd=1/Rs= 2W /- 50% or more depends greatly on your max Tj you allow above your heatsink This require more detail to prove, so check your design tolerances and thermal resistance.For S x P arrays it would be, $V_f=2.8*SS/P*If*Rs$ Then heatsink should be Rca= Watts/deg C to to be less than Pmax/40 deg C for a good design., better if poss.Ref for more thermal details.If you do not know the SxP array , choose S from Vf/3 and then estimate P and so Rs and Pd will be for the array vs individual.If you want to use a Vcc then add to Rs for desired If and chose Vcc less than 1 LED Vf drop above string for choosing Rs for efficiency and Pd.Should I buy LG brand LED tv?Samsung and LG both manufactures quality / reliable LED TV ( LCD-LED back light ). Samsung / LG also use own made LED display panel. Samsung is the very first LED TV maker, is ahead LG 8 month. but LG coming out fast and hold equally LED TV technology compare to Samsung / Sony / Sharp. Samsung / LG or other brand LED TV come with difference range of models to suite consumers requirement. is really not fair to simply compare just based on “ brand “. compare with “ same range “ --- mid end / hi end models , i should said no significant difference between Samsung / LG . as LG “ kick out “ Sony become world second TV maker, that proven LG TV is quality and reliable. LED TV from world No 1 and 2 TV maker , should be equally quality !LED's with switch on a 12v supplySeries circuitsimulate this circuit - Schematic created using CircuitLabFigure 1. Five LEDs in series.LEDs are not linear (current is not proportional to voltage as in a resistor) and small increases in voltage can cause a large increase in current to the point of destruction. A series resistor will limit the current to a safe value provided voltage does not deviate too much. Since you require 2 V per LED at 10 mA that means we need to drop another 2 V in the series resistor. From Ohm's Law, $ V = IR $, we can calculate $ R = frac VI = frac 20.01 = 200Omega $. 220 Ω is the next highest standard value. Parallel connectionsimulate this circuitFigure 2. Parallel circuit.This time each LED requires its own resistor which needs to drop 10 V across it. Using Ohm's Law again we get $ R = frac VI = frac 100. 01 = 1000Omega = 1kOmega $.Wanting to power 20 LED's; which small, common, & commercially available battery will give the longest life?Selecting the longest-lasting battery is easy. For a given chemistry, the energy content is proportional to size, so get the biggest one you can. D cells will last longer than AAA cells. A 9V is just six very small cells in series. There are many battery chemistries out there, but it's hard to beat alkaline batteries for long life at a reasonable cost.It does not really matter how you arrange the LEDs, series or parallel, from an efficiency standpoint. Consider these two circuits:simulate this circuit - Schematic created using CircuitLabEach has two LEDs, with the resistors and battery voltage selected such that 20% of the voltage is dropped over the resistors, and 20mA in the LEDs. The power in a resistor is given by $P=I^2 R$.Power in R1: $ (20mA)^2 85Omega = 34mW $Power in R2 and R3: $ (20mA)^2 cdot 42.5Omega cdot 2 = 34mW $This is the rate at which the resistors are converting electrical energy (and indirectly, your battery's chemical energy) to heat. As you can see, it's the same for either circuit.There is also some power lost in the batteries, by their internal resistance. But it can be seen that the current through any of these batteries is the same. BAT1 and BAT2 must supply 20mA. BAT3 and BAT4 must supply 40mA to power the two parallel LEDs, but since the batteries are also in parallel, each supplies only 20mA. Since the current is the same in all the batteries, the losses are also the same.However, if you really want to stretch your battery life, a resistor is not the way to ballast your LEDs. See How can I efficiently drive an LED?.Are there LED bulbs available that offers dimming based on higher frequency PWM (>3kHz)?You can PWM any single LED but domestic LED replacement bulbs have built-in circuit which either cannot be dimmed or it can be dimmed by conventional trailing edge phase-cut circuits operating at 50/60 Hz. On top of that the phase-cut external dimmer circuits do not work very well in conjunction with the light bulb internal driver circuit and can cause the light bulb to flicker st low settings, sometimes at random.I also noticed that if you use a non dimming bulb the 100hz Led flicker is minimal. However all the dimmeable replacement LED bulbs I have tested showed a noticeable 100Hz flicker which I could only measure with my special kit but my daughter find it annoying.I would suggest that for normal use, non dimmeable LED bulbs are best. If a dimming function is needed it is best to buy an integrated luminare which dims the LED's via a high frequency PWM and comes with the appropriate remote control.Why is there no resistor in a christmas LED string light?Each LED has it's own internal resistance. When you consider the typical tolerance on AC lines is 11 Column 84 Row LED Matrix MicroController? [closed]There are three common ways to tackle this kind of problem.As has been noted in the comments using shift registers can give you a huge number of outputs using just a handful of microcontroller IO pins. There are specific LED driving shift registers available that are designed for just this kind of thing, such as the STP16CP05. There are more complex ones, such as the TLC5940 or TLC59116, both of which provide PWM, but that can get in the way of multiplexing the LEDs unless you take great care.Coupling some "normal" shift registers (74HC595) with some suitable P-channel MOSFETs or PNP transistors as high side switches to drive the rows (anodes), along with a bank of STP16CP05 shift registers as the column sinks (cathodes) could be achieved using just three pins on the microcontroller (clock, data and latch).For lots of LEDs though this rapidly becomes quite hard for the microcontroller to update fast enough. So: You have already created an 8x8 matrix using 16 pins of a microcontroller. So why not do the same again, multiple times? Have all of them communicating on a bus (SPI, I2C, etc), and send instructions to each module telling it what to display. Each individual module is then responsible for performing the multiplexing and refreshing of the image on its portion of the screen. There are also dedicated chips designed for this purpose, such as the MAX7219 which can directly drive an 8x8 matrix through an SPI interface.LEDs such as the WS2812 and similar connect in a chain using a simple serial protocol. You can connect many hundreds of these LEDs together, and often come as pre-manufactured strips sold by the metre. These are an excellent option if you want to create a full-colour displayTemperature Controlled LEDIt's running in an indoor environment, and I would expect it to be in the range of 15-30°C. It would be a few different channels with one LED, LED Vf 2.1V, up to 100mW, probably something similar to EPITEX L625-36The best way to keep LEDs running cool is to use an LED with high efficacy and a thermal pad. The Epitex L625-36 50 mA, 2.2V Vf = 110 mW, outputs 23 mW of light. Efficacy = 23/110= 20.9% The problem is cooling an LED embedded in 3 mm of epoxy resin with no thermal pad. Now if you were to use a Cree XP-E P/N XPEBRD-L1-0000-00901 It has a photon output of 2.10 µmol/s (400 mW Radiant Power) 350 mA x 2.2V Vf = 770 mW total power dissipation. Efficacy = 400/770 = 52%.52/20.9 = 249% so you will have 2.5x less heat to deal with due to efficacy. Plus the total power dissipation will be lower due to a 10% lower Vf at lower current. Less heat flux makes thermal management easier. 15°C variation in ambient is the issue. If ambient were kept constant there would be no LED junction temperature deviation once the system reaches thermal equilibrium. Red LEDs are more susceptible to variation in temperature that all other colors except amber. Temperature vs. IrradianceRather than thermal management you may want to consider using a photo diode rather than thermistor to keep the irradiance constant rather than temperature. The circuit below (yellow) will regulate LED temperature but does so by changing the current which affects irradiance. But if you replace the thermistor with a photo diode it will keep the irradiation constant. This circuit incorporated with a linear constant current regulator would keep it very simple with very little ripple current.

They use a separate halogen bulb to illuminate the street, but use a more efficient LED bulb that can be adjusted to turn on or off in an appropriate manner. This type of solar street lights are usually controlled by a button on the lamp's control panel.Most of the people in the world are using solar street lights to make homes. They are not only powerful, but they are also lightweight. A good solar street light is built to last for years and has an excellent safety feature. There are many different types of solar street lights, but they all come with some common features. For example, a solar street light can be powered by a battery or by a battery charger. If you want to have a home that is just as comfortable as you would be able to use your own power source, then a solar street light is the way to go.This article will show you how to install a solar street light in your home. A good solar street light is one that can make your home feel a lot more welcoming and safe. The most important thing to consider is that it is an investment that will last you a long time. It is also one of the most cost effective ways to save money on your utility bills. You should know the kind of solar street light you want before you buy it.Overall evaluation of the best solar street lightIt is always nice to see how much we can improve on our last report. It is very important to make sure that we do not get wrong and we need to take into account our personal opinions. I want to take this opportunity to tell you about my experience with solar street light and how it has helped me understand the different types of solar street light and how they work. This article will help you understand the different types of solar street light and how they work.If you have been looking for a reliable solar street light then you should look at the impact of solar street light on your lifestyle. If you are planning to buy a solar street light then you should go for a better option. It is very important to choose the best solar street light that is available in the market. This will give you a better view of the current market and how much it will cost. You should also check if the solar street light has any battery power source.The system we use today is far more powerful than any device we have today. The main problem with using solar street lights is that they do not produce enough light to last for long periods of time. We have to replace them every five years or so. This means that if we don't replace them every year then they will only be running for a few years. Solar street lights are really nice because they are easy to install and use. They also have some built-in cameras that can record images on them.In general, we can say that the overall system performance of solar street lights is better than in general. For example, if you are planning to build a home or have an emergency service call 911, then it is important to use a single bulb and replace it every two years. This will save you a lot of money in the long run. However, there are some other factors that affect the overall system performance. The most important thing is to know what kind of bulb you are using and what kind of bulb you are using.
IGBT of Fuji Motor Electronic Equipment Technology
IGBT of Fuji Motor Electronic Equipment Technology
The IGBT technology of Fuji motor and electronic equipment technology has been commercialized since 1988 and has been supplied in the market so far. Figure 1-3 shows the development process and application technology of IGBT products from the first generation to the fifth generation. Epitaxial wafers are used in the first to third generation IGBT, and the characteristics are improved by optimizing life cycle control and refinement technology of IGBT. Then, the fourth and fifth generation products have achieved significant characteristic improvement through the transition from epitaxial wafer to FZ (floating zone) wafer. In this regard, the design policy of IGBT has changed greatly compared with the past.Firstly, the basic design idea of IGBT using epitaxial wafer (series products up to 600V of the third to fourth generation, called "breakdown type") is as follows. In order to realize the low-pass state voltage during IGBT conduction, a large number of carriers are injected from the collector side to fill the IGBT with high concentration carriers. In addition, the n-buffer layer specially set to maintain the high voltage forms a very thin n-layer, so as to realize the low-pass state voltage. In order to realize fast exchange, life cycle control technology aiming at the rapid disappearance of carriers filled in IGBT is also adopted (through these, low exchange loss (eoff) can also be realized). However, once the life cycle control technology is applied, even in the normal on state, due to the effect of this technology (the carrier transport efficiency decreases), there is a problem of increasing the on state voltage, which can be solved by further high carrier injection.In short, the basic design concept of IGBT using epitaxial wafer technology can be simply summarized as "high injection and low transmission efficiency". In contrast, IGBTs using FZ wafers (series after the fourth generation 1200V) adopt a reverse basic design to inhibit the injection of carriers from the collector side and improve the transmission efficiency by reducing the injection efficiency. In the above-mentioned design concept of IGBT using epitaxial wafer "high injection and low transmission efficiency", the carriers that are not easy to be injected are forcibly suppressed through the control of life cycle, which not only limits the improvement of characteristics, but also increases the standard deviation of on-state voltage characteristics through the control of life cycle, It is very disadvantageous to the large capacity required for parallel use with increasing requirements in recent years. The technology developed to overcome this problem is a new IGBT using FZ chip (NPT: non punch through (used from the fourth generation IGBT) / FS: field stop (used from the fifth generation IGBT) - IGBT). The IGBT does not adopt life cycle control. Its basic design idea is to control the impurity concentration of the collector (P layer), so as to inhibit the carrier injection efficiency. However, in order to realize the characteristics superior to the IGBT using epitaxial wafer, it is also required to realize more than one hundred for the 1200V high voltage resistant series IGBT μ M (the thickness of n-layer in NPT and fs-igbt using FZ wafer ≈ the thickness of chip (wafer). The thinner the thickness, the lower the on state voltage can be generated). In short, it is not too much to call the development of IGBT using FZ chip a challenge to chip thickness.Fuji electric and electronic equipment technology has solved these problems. Starting from the fourth generation 1200V series - IGBT, it has realized the commercialization of "s series" constructed by FZ chip NPT. In addition, 600V series technology with higher thickness requirements is further developed, and 600v-u2 series (fifth generation) is being commercialized. In addition, in 1200V series - the fifth generation "U Series", in order to improve the performance better than s series, NPT structure has been changed to FS structure.The so-called FS structure does not use the life cycle control technology. While following the basic design concept of "low injection and high transport efficiency" of carriers, an n buffer layer to maintain voltage is set on the FZ wafer, so as to realize the IGBT structure thinner than the NPT structure. Through this change, 1200v-u series realizes the low on state voltage characteristic better than s series, and completes its commercialization. In addition, this technology is also used in 1700V series high voltage withstand series, and is also starting to be commercialized.Figure 1-3 changes of Fuji motor electronic equipment IGBT application technologyIn addition, Fuji electric and electronic equipment technology is also refining the surface structure indispensable for the improvement of IGBT characteristics (IGBT is formed by multiple IGBT plates. Through refinement, the more plates, the more low on-state voltage can be realized). Up to the fourth generation products, the planar structure (the structure of planar IGBT) has been used to promote refinement, so as to improve the characteristics. However, starting from the fifth generation products - 1200 and 1700V series, the grooved IGBT technology slotted on the Si surface and constituting IGBT has broken the subtle technical barrier and achieved unprecedented characteristic improvement. Figure 1-4 shows the change of characteristic improvement of 1200V series.Figure 1-4 improvement of balance characteristics
Is a Metal Roof Right for You | Billy
Is a Metal Roof Right for You | Billy
Is a Metal Roof Right for You | BillyMetal roofs, first popularized in the 19th century, have enjoyed a long history in American culture, and are now enjoying a resurgence in home building and restoration due to the growing popularity of both industrial and farmhouse styles. Tin roofs were commonly used for homes and barns in the south and are still fairly common in states like Ohio, but these have been replaced by milled steel and more modern materials. Modern metal roofing comes in several gauges and a variety of finishes and styles to complement your house and yard. Exposed and hidden fastener roofs are available with seamless standing (hidden) being a favorite among architects. Seamed roofs require visible grommet screws , whereas the seamless-style roofs involve a different type of concealed-fasterner installation. Standing seamless roofs generally have more robust trim. Traditionally, metal roofs consisted of vertically oriented panels with vertical seams. Modern technology had yielded an abundance of other profiles, many mimicking other roofing types. Read on for more information. Early American metal roofs were often painted for preservation and new roofing improves upon that with durable powder-coated and other advanced finishes. A range of metallic finishes are available to mimic metals such as copper and galvanized metal. A "traditional" red oxide complements barns and imparts a rustic look to older buildings or even newer homes. Imagine a square schoolhouse with a stark barn red roof. Grays, blues and certain greens are also manufactured with hunter-type greens pairing well with cabins and other rustic homes. If you like old-fashioned, galvanized roofing, there is a zinc and aluminum-impregnated panel called galvalume that offers great longevity and an attractive sheen. Note that galvalume is a different process than painting and usually has a slightly different warranty. While traditional shingles only come in subdued colors, painted metal finishes are available in vivid primary and secondary colors, making them ideal for the modern and adventurous. These tough finishes generally come with a warranty that ranges from 25-40 years. Ask your contractor for samples or order some online from manufacturers. There are a lot of profiles available for metal roofs from more architectural, flat-ribbed modern types to more classic, simple rib styles like those found on barns (and in the old rural South). If you can get a contractor to bring larger samples and see them on top of your roof, it becomes much easier for you to visualize your roof job. It's possible that a modern standing seam roof will make a nice contrast to an older farm or that a more traditional style will add some excitement to a newer home. Do not be afraid to get experimental. Along with vertically-oriented roofs, shake, tile and shingle-style metal roofs are gaining popularity in the construction field. Clay tile roofs are difficult to replace, and modern roofing materials are frequently being used on historic buildings (where historic preservation is not an issue). These metal styles are also useful for additions as they can provide contrast to other building materials for a melding of styles or postmodern appearance. Metal roofing materials are, in fact, candy for architects and other designers as they search for new architectural expressions. Metal roofing is not limited to interiors either. You will find them used creatively in home (and business) interiors as ceilings (check the indoor rating), as partial walls, and for components of industrial-style furniture. One of the big advantages of a metal roof is that it has a much greater life expectancy than a shingle roof. The metal itself can last 50-100 years-way beyond any asphalt shingle (with a 10-15-year average life expectancy). However, the paint finishes are rated for fewer years (30-45-still a great warranty) and you may decide you have to repaint your roof after 30 or 40 years. If that is the case, there are good paints available for painting metal, as well as technicians who know how to prep and paint it. That said, metal will still outlast any asphalt shingle. Metal roofs generally cost more than shingle ones, however, the long-term value, as stated above is much greater, making the overall expense less. Also, the cost of a metal roof varies from state to state. Generally, there are more contractors skilled in metal roof installation in states such as Ohio where they are more common. Be sure to get multiple quotes if you are considering a metal roof. Screwed roofs are less expensive than standing seam but, as previously mentioned, may mean you need to have it inspected for loose fasteners on occasion. The cost for roofs varies so much, that you will really need to get estimates from local contractors to determine if a metal roof is right for you. Standing seam roofing generally has prominent ribs and interlocking, hidden-clip-fastened seams and the fastening system and trim are completely different than those of the screw-in type (the latter found commonly on barns). There are reasons you might choose one or the other, however. Obviously, if you want clean lines with no exposed fasteners, standing seam is for you. Standing seam roofs tend to show imperfections and may appear wavy or reflect light that accentuates those imperfections, or even waviness in the roofing itself. An old roof with a lot of sagging will highlight this aspect. Corrugated roofing or most visible-screw types of roofing may better conceal imperfections. The gauge of the metal also impacts how well the roofing conceals the underlying structure. If you are looking for a more industrial look, you might appreciate the exposed fasteners on the screw-fastened sheets. Exposed screw roofs are generally less costly than standing seam but when installed properly, both are good options for your home. Metal roofs come in several gauges, 29, 26 and 24, with the higher numbers being the thinnest material, and the lowest number being the most durable. Make sure you know the recommendations for residential applications before signing a contract with a roofer. 29 gauge may be used for most residential applications, but for severe weather areas, 24 might be better. Some professionals recommend 26 gauge for homes and 29 for barns and other outbuildings. There may be local code requirements as well. One way that a contractor might cut corners is by using a really thin-gauge metal on your home. The most practical advantage is that you likely will not have to replace a metal roof in your lifetime, provided you are happy with the color and paint. If you tire of it, you, of course, can have it painted, which should not be a huge expense. Shingles, on the other hand, need replacing every 15 years or so. Even the newer dimensional shingles are still going to require replacing and maintenance. Most people with asphalt shingles have, at one time or another, had them blow off in a storm. A metal roof can occasionally suffer from storm damage in hail or really high winds, but not to the same extent as asphalt shingles. Some insurance companies even give you a break if you install a metal roof (this is not likely in coastal areas, however). Chalking and fading may be an issue for metal roofs down the road. However, there are government standards for acceptable fade amounts which can usually be found on the manufacturer's website. This refers back to the issue of painting. Metal roofs are faster to install, depending on the skill of contractor. Need a roof fast? Do you have severe storm damage? Metal might for you then, provided it appeals to you aesthetically and you can find skilled tradespeople in your area. Metal roofs are much lighter than shingles, meaning less stress on the roofing structure (and the workers). If you are building from scratch, or using for a garage or shed, the requirement for supports may be reduced. Check your local building codes for more information. As previously mentioned, metal roofs are more cost effective than shingle ones in the long term, given the lower life expectancy of shingled roofs. The best way to calculate cost effectiveness is to get some actual quotes from roofers with the knowledge that many roofers will try to talk you out of a metal roof for the simple reason they do not know how to install them. It is a specialty skill and, depending on your location, there may not be many installers. For many homeowners, some of the decision will boil down to aesthetics. People tend to either really like or really hate the appearance. Be sure to ask yourself the following: • Will I love this roof and its color in 20 years? • Will I keep this home or sell it? • Are there any other governing bodies or local codes I need to be aware of before installing? One of the biggest concerns you read about metal roofs is if they are noisy. People might claim the pinging keeps them awake. Conversely, some describe the noise as romantic. Installed over roofing underlayment (plywood), a metal roof is not going to have the same acoustics as, say, a barn with no underlayment, which can be extremely loud when it rains. If this is a concern, you can request a thin layer of foam insulation placed over the existing roof (and beneath the metal roof panels), as it dampens the sound. Foam insulation will also reduce the imperfections that might show through the roof (especially on standing seam, non-corrugated roofing). A huge advantage to metal roofs, and one that you seldom see referenced online, is how well they hold up to snow. While standing snow on asphalt can cause damage and leaking (thus the need for roof snow rakes), metal roof owners will be pleased when, as the sun heats the roof up, they hear the whoosh of a small avalanche as the snow slides off the house onto the ground. Of course, you will probably want to remove this snow from around your foundation, but it beats having to rake it off. Because metal is not combustible, many metal roofs have a really high fire rating (class A). Of course, the materials used beneath the roof also impact the rating. For instance, if you did not tear off the asphalt shingles before installing the metal, they would be included in your combined fire rating. Metal, unlike wood or asphalt shingles, is resistant to mold, rotting and insect infestations. As long as it's properly installed, it should last as long as your house. A variety of paint finishes are available, from subdued neutrals, to metallic copper, to bright primary colored paints, making it versatile for both historic and modern homes. The long-term cost beats most other roofing materials, making it a good roof for the long-term home owner. If you buy a metal roof, buy it because you love it, as you are the one who is going to be enjoying it each time you pull in your driveway or spend time outside.

If you are not going to spend that much on your surface then go to an art store and buy a paper of a weight no less than 120 lbs. The paper weight means that with one hundred sheets of that size the package weighs 120 lbs. Any thing lower than that weight is rather dicey for watercolours although I have worked a lot on 90 lbs paper it is not as good to stretch. Be advised that you have two types of pressed papers to work with. A cold press is very rough on the surface, that is to say that it has a large tooth to the paper. A hot press is a very smooth paper. Further more, if you are buying in single sheets find the water mark before you do anything. The water mark is visible by holding the sheet up to a strong light and you can usually find it in the lower right hand corner. It will stand out lighter than the paper around it and you can see the name of the company or the company logo. If it looks backwards then you have the wrong side to paint on. The face of the sheet that you can see the watermark correctly is the proper side to work on. It takes the colour more readily than the backside and has been groomed for your paint. Always paint on the face of the sheet where the water mark is. If you are halving the sheet, then mark the proper face with a slight mark of a 2H pencil to show the proper face on the halved sheet that does not have the watermark. There are also watercolour pads that can be procured at stores like Staples. They are blocks of paper bound together on one pad by a strong rubber seal on all four sides and this assists in the drying of the paper. When you paint in water your paper will warp, and go into valleys and hills so to speak. If the paper is not stretched properly it will dry that way, but these pads will keep the paper taught so that when it does dry the paper will draw taught again flattening itself out. One word of encouragement though. Water colour is one of the most difficult mediums to master. It looks simple but simple aint easy. So to allay any frustrations I will give you the first and cardinal rule of watercolours. " The first five-hundred watercolours you do? THEY DON'T COUNT". All the best to you.

Which Brand of Bluetooth Headset Is Good? I Recommend Several Easy-to-use Bluetooth Headsets
Compared with wired headphones, Bluetooth headphones have incomparable advantages: unrestrained, compact and convenient. After all, the original intention of Bluetooth headphones is to replace wired headphones. Moreover, with the leap in coding and decoding technology of Bluetooth headphones in recent years, they can match wired headphones in sound quality, which makes more and more people begin to use wireless headphones, As a trendsetter of the times, the student party must be at the forefront, so today Xiaobian has sorted out some Bluetooth headsets suitable for the student party and whose sound quality is comparable to that of wired.First, Nank Nanka Lite ProHighlight: Qualcomm Bluetooth 5.2, good sound quality, game acceleration modeRecommendation Index: 5 starsAt present, poor sound quality and unstable connection are common in the Bluetooth headset industry. The official promotion of the new national product Nank Nanka headset is that it can buy a thousand yuan brand level for 20% of the price. The materials are luxurious.

Qualcomm Sword Points to the Gateway of Technological Innovation of the next Generation of Smart Pho
Qualcomm Sword Points to the Gateway of Technological Innovation of the next Generation of Smart Pho
On the occasion of the 10th anniversary of Qualcomm Xiaolong processor, Qualcomm began to use the newly released Xiaolong 845 to point to the gateway of technological innovation of the next generation of smart phones - artificial intelligence.On December 6, at the second Xiaolong technology summit in Hawaii, Qualcomm announced the launch of the new Xiaolong 845 mobile platform. Please note that this mobile platform produced by Samsung's second generation 10 nm FinFET process (10lpp) can be called the most powerful mobile chip in the world so far.More importantly, from Xiaolong 845, the industry has seen Qualcomm's more rational layout posture in this era of artificial intelligence: it does not pursue the extreme performance of artificial intelligence on a single chip, but has walked out of its own path in the direction of integration and ecology.The superior performance of Xiaolong 845 is officially condensed by Qualcomm into five Keywords: "immersion, AI (Artificial Intelligence), security, connectivity and performance"."Qualcomm Xiaolong 845 points out a way to the differentiation of mobile phone products in 2018 for mobile phone manufacturers who are stuck in the quagmire of product homogenization today."Sun Yanbiao, President of the first mobile phone Research Institute, pointed out that 2018 is the first year of smart phone artificial intelligence. The face recognition, fingerprint recognition, speech recognition, information recognition and other recognition functions of previous mobile phone products will be organically combined from the past recognition island to form some specific applications of artificial intelligence."Today, the timely release of Xiaolong 845 will become the strongest weapon for mobile phone terminal manufacturers to prepare for the first year of artificial intelligence in 2018." Sun Yanbiao said that with this weapon, mobile phone terminal manufacturers will show a trend of 'Eight Immortals crossing the sea' in 2018. ".Cornerstone of artificial intelligenceAll this comes down to the superior performance of Xiaolong 845.In fact, each generation of Qualcomm's flagship processor products will be planned three years in advance. First, we will understand customer needs, launch the architecture, and then discuss with partners in all links such as operators, mobile phones, software / hardware and cloud. We will design new chips according to the collected information. In the process, we will conduct multiple rounds of testing and modification to ensure that the products are perfectly available when delivered.Therefore, the five keywords "immersion, AI (Artificial Intelligence), security, connectivity and performance" can also be regarded as the keywords that Qualcomm has judged and responded to in the face of market demand in the past three years.In the last two years, artificial intelligence is one of the hottest concepts in the whole technology industry. In a mixed environment, it has brought great changes to many industries and confusion to many industries.For example, how do chip manufacturers eat artificial intelligence cake? In other words, how to deal with the possible change reshuffle brought by artificial intelligence?Relying on the deep learning bonus, NVIDIA's GPU turned over overnight and the serfs sang, which made everyone see both opportunities and threats. Up to now, almost all chip manufacturers have come up with their own ideas and products in the direction of artificial intelligence.Of course, CPU, GPU, NPU and DSP are more suitable for artificial intelligence. Each manufacturer has different positions and strength basis, and naturally has different ideas.As the leader of the mobile communication industry, Qualcomm will not be absent. Previously, Qualcomm has said that it will have a dedicated hardware architecture to support artificial intelligence.Today, on Xiaolong 845, we saw the hardware architecture based on vector computing.In an exclusive interview with the media, Alex katouzian, senior vice president and general manager of mobile business of Qualcomm, said that the AI computing of Qualcomm chip has started from Xiaolong 820, while Xiaolong 845 is the third generation, and its processing capacity has reached three times that of the previous generation.However, to have a deeper understanding of Qualcomm's AI strategy, we can't just look at the improvement of DSP architecture. Also understand NPE (neural processing engine).Taking NPE (neural processing engine) as the core, CPU, GPU and DSP form a heterogeneous AI platform, and then cooperate with partner applications to build an artificial intelligence business ecosystem, which is the panorama of Qualcomm's artificial strategy.Therefore, unlike the SOC of Linlin 970, which centrally executes AI tasks through authorized IP and NPU, Xiaolong 845 adopts a heterogeneous AI platform to conduct distributed scheduling of AI operations.For example, algorithms that require high floating point capability mainly run on GPU; Algorithms that mainly need fixed point capability are completed on DSP.If you only look at the specifications of each independent kernel, they all have their own advantages, but artificial intelligence is changing all the time, the market is changing rapidly, and the algorithms are also changing. Compared with a single customized hardware, more diverse and flexible artificial intelligence hardware is a better choice at present. Qualcomm said that according to Qualcomm's analysis, the combination of DSP and GPU is the best combination, and the cooperation of libraries, SDK and framework needs to be optimized to ensure the efficient operation of AI.In addition, it will fully schedule the resources and capabilities of the CPU and other units, match different voltage and frequency domains, and finally achieve the balance between the best performance / experience and the lowest power consumption / calorific value.In addition, Xiaolong neural processing engine SDK will also help software developers and OEMs directly deploy the hardware advantages of Xiaolong 845 to applications, and use hardware to accelerate AI operation, so as to further reduce power consumption.Busy industrial layoutIt is worth noting that while emphasizing artificial intelligence, Qualcomm snapdragon 845 has always emphasized the balance between the best performance / experience and the lowest power / heat consumption.Because, with the current status of chips, batteries and related technologies, in extreme cases, if the artificial intelligence computing power is fully turned on, it can even consume all the power of an ordinary smart phone in half an hour.Obviously, this is unacceptable to the user's actual use experience.Qualcomm's previous consumer research in China and the United States showed that 65% of respondents in the United States wanted to be able to surf the Internet at any time, and 51% needed stronger endurance; In China, on the contrary, 51% of users want to connect to the Internet, and 60% of consumers pay more attention to endurance.When everything is ready, the support of partner manufacturers has also become the key to whether Qualcomm can become a leader in smartphone artificial intelligence.Interestingly, also at the second Xiaolong technology summit, Baidu and Qualcomm jointly announced that they would work together to optimize Baidu dueros's artificial intelligence solution on mobile phones on Qualcomm Xiaolong mobile platform, including the upcoming Xiaolong 845 mobile platform.It is reported that the strategic cooperation will make use of the accumulation and expertise of the two companies in the field of artificial intelligence, use Qualcomm aqstic software and hardware to optimize dueros conversational artificial intelligence system, and launch a complete set of artificial intelligence voice and intelligent assistant solutions for global smart phones and Internet of things terminals.Meanwhile, Qualcomm's 5g pace is also accelerating.On December 15, Qualcomm, ZTE and wind tre jointly announced that they would cooperate to carry out interoperability test and OTA field test based on 3GPP standard 5g new air interface (5g NR) specification. The test will verify 5g services and technologies, so that the standard 5g new air interface infrastructure and terminals can be ready to support the timely deployment of commercial networks."2018 is the first year of mobile artificial intelligence and also the 1.0 era of mobile artificial intelligence. With the 5g speed like optical fiber and the support of big data in the cloud, we will enter the 2.0 era of mobile artificial intelligence," said Sun Yanbiao.
