If you’re serious about it then you’re going to need a good digital SLR, a selection of lenses and href="http://www.makeuseof.com/tag/10-cool-accessories-photographer/">a decent set of extras to keep you snap-happy.

There’s a startling array of accessories out there for the amateur enthusiast, and though many are cheap there’s plenty that aren’t. Luckily, you’ll be pleased to hear that many of those costly bits of plastic and card are simply that – plastic and card, which can be built for a fraction of the cost.

Those of you who don’t have the cash to flash and enjoy a little challenge will find some of the do-it-yourself projects in this list satisfying, especially when you’re saving money (probably to buy more lenses, if you’re anything like me).

href="http://strobist.blogspot.com/2006/07/how-to-diy-10-macro-photo-studio.html">The DIY Softbox

If you’ve ever taken an interest in href="http://www.makeuseof.com/tag/started-macro-photography/">macro photography then pay attention. A softbox is essentially a light tent, designed to soften harsh light and shadows to provide a nice even exposure and near-perfect lighting.

style="text-align: center;"> class="aligncenter" style="border: 0pt none;" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2010/09/softbox.jpe" alt="digital photography accessories"/>

Pretty much every “product shot” of href="http://www.makeuseof.com/dir/gdgt-electronic-gadgets-wikipedia/">any gadget you own will have been shot in one of these, and you can quite easily customise it to suit your own demands. A nice shiny floor tile from your local DIY store is all it takes to sex one these up!

To make one you’re going to need an old cardboard box, some black and white card and a source of light. If you don’t have a flash unit, you can fire remotely (either wirelessly or with a hot-shoe cord) then you could use a desk lamp or even bright torch, just href="http://www.makeuseof.com/tag/tips-digital-photos-require-photoshop-fixes/">remember your white balance.

href="http://www.xs4all.nl/~wiskerke/artikelen/string.html">The String Tripod

The least-conventional tripod ever, this string tripod attaches to your camera’s usual tripod mount point so that a length of string is left hanging from your camera. Your foot is then used to hold the string tight in the position you would like to shoot, and adjusted accordingly.

style="text-align: center;"> class="aligncenter" style="border: 0pt none;" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2010/09/stringtripod.jpe" alt="digital photography accessories"/>

The tripod works by using the tension in the string to keep the camera steady. It won’t keep your camera amazingly still but should work enough to facilitate shooting in lower light conditions. The tripod is designed purely to get href="http://www.makeuseof.com/tag/the-basics-of-aperture-and-shutter-speeds-for-beginning-photographers/">a couple of extra stops of light into your camera without the blur.

To make it, you’ll need an existing tripod plate (plastic’s probably best, as you’ll need to drill a hole) and some sort of string or chain. There’s nothing to say you can’t modify this design, as long as it’ll fit in a tripod mount point then it’ll work. Retaining screws for US license plates apparently work well, if you’re that side of the pond.

href="http://www.adidap.com/2007/12/20/diy-poors-man-ring-flash/">The Poor Man’s Ring Flash

A proper ring flash can often end up costing more than what your camera is worth, so if you’re still new and not made of money then you might as well try and MacGyver yourself something instead. This guide will show you how to make a basic yet functional ring flash to bring out the best in your href="http://www.makeuseof.com/tag/5-photography-and-photoshop-tips-for-the-perfect-family-portrait/">portraiture.

A ring flash is designed to light the subject from your lens’ point of view, minimising shadows in the wrong place and providing a vivid, well lit exposure. The DIY ring flash won’t perform as well as a professional bit of kit, but href="http://www.pbase.com/duncanc/image/84869713/large">the results aren’t bad.

style="text-align: center;"> class="aligncenter" style="border: 0pt none;" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2010/09/ring2.jpg" alt="photography accessories" />

Depending on the flash you are using (this should work with both the internal flash and any flash guns you might have) cut the milk carton to size, cut a hole big enough to slide your lens through and shoot away. If you’re reading this and you’ve got a point and shoot camera, don’t worry href="http://www.instructables.com/id/Point-and-Shoot-Ring-Flash-Diffuser/">you can join in too.

href="http://www.diyphotography.net/the-party-bouncer-is-back-in-business">The Flash Bounce Card

The simplest trick of all can transform your harsh sub-par built-in flash into a glorious bounce flash for a whopping $0. As long as you’ve got a piece of white card (a business card works well) and some elastic or rubber bands, you’re laughing.

Position the card in front of the flash so no light can leak directly into your shot, so that when your flash fires the light is projected upwards and bounces back down into your scene. It’s no replacement for a full-on bounce flash, but you’ll be surprised at how well the shots will come out considering you never spent a penny.

style="text-align: center;"> class="aligncenter" style="border: 0pt none;" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2010/09/bouncecard.jpg" alt="photography accessories"/>

This will also work to help diffuse or even tint harsh light coming from flashguns, much like the picture above.

href="http://dslrblog.com/how-to-make-a-diy-flash-bounce-diffuser/">The Flash Gun Diffuser / href="http://www.instructables.com/id/DIY-Gary-Fong-Lightsphere/">Light Sphere

This one works in a similar way to the bounce card, but is aimed at those who have already coughed up the money for a fancy flash gun. There’s no right or wrong way to do this, as there are so many different versions floating about online.

style="text-align: center;"> class="aligncenter" style="border: 0pt none;" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2010/09/diysphere.jpe" alt="photography accessories"/>

This particular design suggests using bubble wrap to create a hollow tunnel that sits on top of the flash unit, to diffuse light directly at the subject. I myself prefer the tried and tested href="http://www.digital-photography-school.com/diy-flash-diffuser-airline-barf-bags">sick bag and rubber band diffuser, as the airlines tend to keep me stocked up for free.

You’ll be amazed at how well it works, especially considering an official Gary Fong Lightsphere (which is just plastic after all) can set you back about $50.

Conclusion

Hopefully this list will at least give you an idea of what you can achieve with effort as opposed to money. These DIY accessories are often intended to deliver a sample of what the real thing can do without laying down the cash. If you find that you’re especially fond of one of your creations, href="http://www.makeuseof.com/dir/tipjar-money-saving-tips/">then maybe it’s time to start saving for the real thing. If it’s good enough, why bother?

Chip Figures Board Applications are very broad. Basic support IEEE1149.1 standard DSP chips, and circuit board formed a boundary scan chain, to support boundary scan testing.

In the DSP circuit board in such a class IC They are non-boundary scan devices in the circuit board edge Connector And formed by the DSP chip boundary scan chain between. This part of the device functional test difficult. First, the DSP board with an independent timing, we can not separate the external interface by using the traditional method of input test vectors to test; Second, boundary-scan test can only be connected with the DSP chip interconnection pin test short-circuit fault can be detected, but difficult to functional tests.

This paper, boundary-scan test technology with the combination of traditional testing methods for functional testing of these devices provides a new choice. A test method

In IEEE1149.1 standard, providing four mandatory instructions: bypass instruction (BYPASS), sampling instructions (SAMPLE), pre-installed command (PRELOAD), interconnect test instruction (EXTEST). Interconnect testing according to the sampling instructions and directives of the working principle of the use of boundary scan cells can capture and drive pin signals. Using this feature of boundary-scan device can be achieved with a DSP chip on the circuit board as shown in Figure 1 Central African boundary-scan devices send a signal acquisition and incentive vector to the boundary-scan test technology with the combination of traditional testing methods to realize testing of such devices.

This kind of testing can be divided into two situations:

A) as shown in Figure 2, solid line, non-boundary scan input device connected with the edge connector, output and DSP chips. Fault diagnosis using the software, the digital I / O modules produce a stable excitation vector, excitation vector through the edge connector anyone to the non-boundary scan devices, the response vector generated by the boundary-scan devices connected to it (DSP chip) to get through boundary-scan access to the serial output for the response vector and display. According to the working characteristics of the device under test can be analyzed theoretically expected response vector, the vector response obtained compared with the expected response vector, if the comparison results to differ, indicating possible functional device failure.

B) as shown in Figure 2, dotted line, non-boundary scan devices connected to the input and DSP chip, the output is connected with the edge connector. Use of boundary scan test software, test stimulus vectors were related to pin serial shift (with non-boundary scan devices connected to the pin) of the boundary-scan unit, and drive to the pin, the test stimulus into the device under test, the response vector generated by the edge connector from the digital I / O modules to acquire, read by the observation of fault diagnosis software. According to the working characteristics of the device under test can be analyzed theoretically expected response vector, the vector response obtained compared with the expected response vector, if the comparison results to differ, indicating possible functional device failure.

2 Test system components Hardware test system shown in Figure 3. VXI-1394 VXI system uses an external control; zero-slot module for the IEEE1394 serial communication protocol conversion for the VXI protocols; digital I / O module type is DIOM-64, each module has 64 I / O channels, three digital I / O modules provide a total of 192 test channels used to provide incentives to the circuit board under test signal and the output signal acquisition circuit board; adapter board for testing equipment and measured the signal between the matching and to the board under test provide Power supply ; JTAG interface controller signals generated by computer algorithms and standard JTAG signals between the transmission and conversion.

Software consists of software ScanWorks boundary-scan test system, fault diagnosis software TestVee, collection procedures and test response vector output incentive program. ScanWorks for the establishment and implementation of the boundary-scan test, the main features include scan chain test, interconnect test, memory test; TestVee used to control the digital I / O module working status; response vector collection procedures and test incentive program under the output is Development of measuring the actual situation in the circuit.

3 Test validation 3.1 circuit board circuit analysis

Tested plate boundary scan chain is composed of six ADSP-21060, JTAG boundary scan test interface to meet the conditions, but the pin signal definitions and ScanWorks JTAG interface adapter system of different definitions, you must re-configure the connection before the test . The device under test SN54LS245 (D33) in the tested panel of the connections shown in Figure 4. D33 of the control pin 19 (OE) by other non-boundary scan device control, where do ground handling; control pin 1 (DIR) connected to the D36A (54LS244) of 14 feet, D36A control pin connected to the edge connector on, so take advantage of digital I / O modules through the control of its working state, to achieve the working status of the D33′s control.

3.2 response vector collection procedures and testing procedures for the development of export incentives

System provided by ScanWorks Macro language programming. Macro language by a compiler and a parser component, access to source code and the compiler generates an executable program and the output parser to obtain an executable program and perform. To DSP chip BSDL (Boundary Scan Description Language) file based on the response vector acquisition program input pin (INPUT) scanning unit programming, using the SAMPLE command for data collection; test stimulus output procedure output pin (OUT -PUT) scanning unit programming, using the EXTEST instruction to achieve excitation output. SN54LS245 data communication direction control for simultaneous testing of two connections, so DAT0-DAT7 separate response vector collection and testing of incentive program to send programming. To note, six DSP shared data bus, must be 6 DSP’s DAT0-DAT7 pin to do the same operation, so as not to conflict with the bus signal.

3.3 Test verification 1) boundary-scan chain test Link test is normal for other boundary-scan test basis, so the link must be boundary-scan test. Connected properly tested board JTAG port, BSDL file associated with ScanWorks into the establishment of the boundary scan chain, and perform link test operation. Tested, the link works properly.

2) functional tests Determine the working state according to D33, as long as all “0″ and all “1″ There is enough excitation signal detection device A and B communication.

A) verification of one kind of love

The Moving Picture Experts Group Layer 3 Audio or MP3 is a digital audio encoding format which is used to store songs and other audio files. The format uses a psychoacoustic model that discards less audible sounds and records more audible sound in an efficient manner. The format is successor of Perceptual Transform Coding (PXFM) and Optimum Coding in the Frequency Domain (OCF) codecs. MPEG1 codec was first published in 1994 while MP2 codec was published in 1995.

The ease of sharing music files popularized the use of MP3 format among the users. This ease created problems related to copyright infringements. Therefore, many online music retailers use their proprietary formats to counter this problem. They use an encrypted digital rights management format that prevents the users from using the music in a way that has not been authorized by music record companies. The quality of sound of a digital audio format depends upon its bit rate to a greater extent. A lower bit rate results in low quality sound. A much lower bit rate may result in compression artifacts. Such artifacts may make those sounds audible which were not present in original music or production.

An MP3 player is a portable digital audio player that stores and plays audio files. Most of these devices use rechargeable batteries and support video playback functions. The players have been categorised on the basis of their storage media. Flash based players hold digital audio files on their internal flash memory. The players consume less battery power as they do not have any moving parts. Some commercial flash based players may have up to 32 GB of flash memory. Hard drive based players read audio files from a hard disk drive. These players come with massive memories. Some of these players may have up to 250 GB of memory, which is large enough to record an entire music collection on a single player.

The third variety of MP3 players is known as CD MP3 players. These players have the capability to decode and play MP3 files that have been stored on a compact disc (CD). The immediate predecessors of these players were MiniDisc players. These earlier players have no support for digital file formats. SeeHan Information Systems produced the first digital audio player on commercial basis in 1997. The player was sold under brand name MPMan in South Korea during 1998. The player was later licensed to Eiger Labs by SeeHan.

Car MP3 players are specially designed to work in a car. These players allow people to enjoy quality music during their travels by road. The players perform many useful functions for the users. They provide the users with a list of their favourite play list and also keep track of their calendar events. These players are made compact so that they can easily be fitted into the available limited free space of a car. The iPods specially use MP3 format as it allows the device to play hundreds of songs at a stretch. Most of these players have USB, SD and iPod connections that add to the versatility of these devices.

Most of the current portable MP3 player come with programmable track memory that allows the users to keep track of their songs. Most of these devices also feature AM/FM tuners and digital anti skips memory. Samsung has launched some of the best selling digital audio players in recent years. Some of the best selling Samsung MP3 players include Samsung YP-P2 Touch Screen 4GB Multimedia Player, Samsung YP-U3 Stick 1GB player and Samsung YP-K5 2GB player. All these players feature TFT LCD display, FM radio and support Multi Language options. The devices come packaged with genuine accessories like an ear phone, a USB cable, CD and stand. The players come with Samsung’s standard 6 months warranty.

Sony, Blaupunkt, Kenwood and Sanyo are the leading manufacturers of digital music players. These companies have rolled many new models of best MP3 players. The devices produce high quality sound by eliminating unwanted sound. These portable digital audio players have redefined the ways people entertain these days.

Thinking of getting a compact usb scanner for your business? if you are interested in buying a digital photo scanning tool but you feel a bit overloaded with all the options out there, you first need to think about what you want to use it for, which will help you to find a scanner that will serve all your needs. The use of a compact scanner can actually revolutionize your daily and weekly data-handling routine, including when the safeguarding of critical material is a factor. Prior to committing to a particular scanner, we encourage you to hear what the experts have to say.

Just like every current and sophisticated hardware device, compact scanners are now less complex and simpler to use. They can answer most of your day-to-day scanning requirements, like cards, photos, receipts, passports, checks or bank statements, etc. In a matter of seconds they provide exceptional pixel resolution in a variety of output. These days, the price of a digital photo scanning tool can be considered a wise investment for the business person as well as the hobbyist.

According to many users, the best thing about these handheld scanners is that they’re so user-friendly and convenient anywhere you happen to be. Installed on the scanners is user-friendly software which makes it simple to acquire professional-level scans from all kinds of input and then save the files to use in various ways. In the case of id cards, the scanner will separate the various parts of the card: the photo, the signature, and all the text of the id card arranged in appropriate data fields, into an external document, your clipboard, or any appropriate application.

Prior to purchasing a digital photo scanning tool take the time to go through these important procedures: (1) what function(s) will your scanner perform? (2) search the internet for scanners you think might fit your needs; (3) how do the different scanners measure up technically? (4) be sure that the manufacturer has a good name and see what other users’ opinions have been; (5) determine the company’s policies on shipping and refunds/exchanges.

Online fundraising is becoming increasingly prominent and accepted…and why not?  You don’t have to go door-to-door, or stand out in the cold, or by your own children’s candy just to satisfy the commitment.  With digital download products, you are not just asking for money.  You are delivering real products with real value.  It is not just looking for a hand-out (although that can be appropriate sometimes), it is giving a hand in exchange.

So what are digital downloads?  They can be eBooks.  They can be software.  They can be still images.  They can be videos.  They can be audios.  Anything that be downloaded directly from some Web Site is a digital download product.  They are dead simple to sell online…especially when it is for a worthy cause. 

Everyone understands selling cookies, or popcorn, or books, or candy to raise money.  You sell a box of cookies for Ten Dollars and your organization gets to keep Five Dollars for your cause.  You have to get the order.  Take the money.  Get the products.  Deliver the products.  You walked miles, or stood for hours, or physically humiliate your co-workers to get the orders.  It was all hard and not terribly efficient.

Now, imagine this…you find a digital product…maybe a piece of software, maybe an eBook, maybe something else.  Perhaps they already have program for fundraising, or perhaps you negotiate one (it is certainly easier if they already have a program).  They establish a way for you to get a direct, online link to a Shopping Cart that is specifically established for you (this may be a unique page, or it may just a program, coupon or reference number on their standard order page).  You let your potential buyers know about the link/product.  They go and buy the product using credit cards, perhaps Paypal.  The owner of the digital product supplies it directly to the buyer.  You get the money.

So how do you let your potential buyers know.  Here are just a few ways:

1)       Put a link and description on your organization’s  website or in their electronic or physical newsletter;

2)      Hand out cards or flyers, or just leave them lying around, with a brief story and a link;

3)      Here is the best-viral email; you send a personal email with a compelling description of the cause you are raising money for and ask people to go to a link a buy the product for your cause.  Tell them how much they will enjoy the product.  Now…here is the best part…send this email to ten of your friends…ask them to copy the main body, add their personal endorsement and send it to ten of their friends.  And repeat.  Sure, at some point the chain will run out…but look at the basic math…suppose 8 of your friends do what you asked…and then for each of them 4 of their friends…and for each of their friends 2 of their friends…and then for one more friend does it.  If you could make $10 per product (a minimum that you should expect here), you just made your organization over $10,000…and you never left the house, never handled money, never handled product.  LIFE IS GOOD!  (And if you want to make this better, just imagine that instead of just you starting this, imagine that your committee of 10 people each started this the same way…you just made $100,000).

There are literally hundreds of other ways to use digital download products for your fundraisers.  The common thread is this…it is easy, it is efficient, and it is effective.

Here is how to get started and what to look for in using digital download products for online fundraising:

1)      Find a digital product that will be interesting to the audience your organization touches.  Selling gambling software to a religious organization may not be a great idea (broadly).  If you are dealing with Moms, look for cookbooks, childcare books, and child protection tools.  Make sure your offering relates to your audience.

2)      Make sure your organization gets a fair return on the sale.  If you are not getting 50% of the Suggested Retail Value, walk away.  If you are not getting at least $10.00 per sale, walk away.

3)      Ensure that the product supplier can accept all reasonable forms of payment online.  At a minimum,  the supplier must accept Visa, MasterCard, Discover, American Express, JCB and PayPal.  Accepting online checks is a nice bonus.

4)      First use suppliers who have established online fundraising programs already established and who can provide tools like email templates, web pages, advertisement suggestions.  You should not have to do all the work yourself.

5)      Make sure you receive funds received at least twice a month and that there is no specific limit on how long the fundraising program can be continued.  At the same time, make sure that you can “pull” the program whenever you want.

6)      You be the boss.  This is your program, make sure it works for you and your organization.

That’s it.  That’s all there is to it.  It isn’t hard.  It isn’t internet mumbo-jumbo.  It is real.  It works.  Try it.  Make it work for your organization today.

Have fun!  Good luck!

Recording, playing and listening to music has never been more fun that it is today. Through the Internet, you can easily download songs and listen to your favorite music anytime of the day and wherever you are. Portable players that have access to Internet or those that can store large number of digital music files are now very affordable, fun to use and designed just right to fit the modern generation’s lifestyle.

What is MP3?

MP3, an acronym for MPEG-1 Audio Layer 3, is one of the most popular digital audio encoding and compression formats being used nowadays and is apparently making an enormous impact on how people store, listen and share music of different genres. It is even now regarded as a standard technology used in greatly reducing the amount of data used to represent audio without altering the uncompressed audio’s sound quality when played.

Compressing Audio into MP3 Digital Music

The compression ratio of MP3 is 12:1, which means that a typical audio file that is 1200 KB big can be converted into a 100 KB MP3 digital music file without corrupting the sound quality of the original. In fact, some MP3 digital music are clearer and sound better since the compression process eliminates portions of the original music that are not too significant to human hearing. There are three ways through which the unwanted portions of the music are determined; among them is psychoacoustics, which is a study of how people subjectively perceive sounds.

MP3 digital music can be compressed with various bit rates (the number of bits of data representing a second of audio), which makes it possible for you to create different sizes and sound quality of an MP3 digital music converted from the same original digital audio file.
