DIY Printed Circuit Boards Could Be Fun

Electronics and appliance stores are deluged with gadgets and devices that seem to be able to address just about every audio visual or data and communication requirement imaginable. There seems to be an off-the-shelf solution for any application effect or outcome one can think of, whether it is playing mp3 audio files, or even detecting radon in your home.

There are, however, rare occasions when no commercially-available product actually exists to fit the bill of some specific requirement that may arise.

One may need to be able to activate alternately flashing strobe lights, or to enable a motor home’s sound system to provide noise-cancellation outputs, or simply to augment a home appliance by adding a DV-power outlet for USB chargers, and not be able to find anything in a store or mail-order site that does exactly that.

pcb-electricalWhen this sort of thing happens, one’s only recourse is to contract someone to build such a device. He may also decide to build it himself. This would mean having to make your own printed circuit board and mounting all the proper components on it. Although this may sound like a daunting task, it isn’t really all that difficult, and could actually be a lot of fun. There is also the great sense of satisfaction you will experience at the end of any successful do-it-yourself project, that is, if it really does go well.

The first step in making the printed circuit board for your one-off electronic gadget is to develop or source the necessary circuit diagram.

There are now websites from which hobbyists can download circuit diagrams and parts specifications for home and shop projects. Before deciding to proceed with one of these projects, it is best to ascertain that all the required components for the devices can be sourced.

When shopping for the electronic components, it is also useful to buy the necessary copper clad board needed for making the printed circuit board, and the ferric chloride solution needed for etching the circuit. Of course, it is necessary to have a drill and the appropriately sized drill bits to make the holes that will admit the electrical contact pins of all the components that you need to mount on the board. Needless to say, the hobbyist should have a soldering iron or gun and an ample supply of solder.

The downloaded or custom-designed circuit diagram should now be transferred to, or drawn directly on the copper clad board with a permanent marker or any means of masking the areas defined by the copper circuit. Some computer printers have the ability to print circuit diagrams on specially made copper clad boards, thereby simplifying the entire process. Once the diagram is made, the entire board should be immersed in a ferric chloride solution to etch the circuit.

The copper on the exposed surfaces of the board reacts to the solution to form a copper chloride compound, displacing the iron which precipitates into gunk in the liquid. After washing off any remaining solvent, the ink of the permanent marker is now wiped off with acetone or some other solvent, – revealing the copper surface of the printed circuit.

All that remains now is drilling the holes on the printed circuit board at the designated points using the correct drill bits, so that the holes for components will fit the contact pins snugly when they are put in. Now, the components such as transistors, integrated circuits, diodes, resistors, capacitors, wire connectors, and everything else are mounted on the back side of the board, and soldered securely onto the copper surfaces on the front side of the board.

It may also be useful to drill larger holes at the corners of the printed circuit board to allow it to be mounted in whatever casing it was meant to be inserted in. Such projects may be far from rocket science, considering how complex present-day circuit boards have become, but they offer a lot of fun and personal fulfillment.

Bye-Bye Boring Lanyards!

boring lanyardLanyards are everywhere. Lanyards can be seen hanging around necks as colorful ID lanyards. There are also lanyards for cellphones, keys, small digital cameras, and eyeglasses. Extreme uses for lanyards include that of safety gear either for hanging tools or preventing falls from high places.

Just stating things about lanyards like that makes lanyards appear boring. Of course, that is aside from the fact that lanyards are super-useful which makes these important. Lanyards saved people from a lot of distress because of lost IDs, keys, and glasses. Rarely do people forget things when these are just hanging around their necks or close to their bodies.

Lanyards can become a valuable part of belonging in an organization. “Boring” is one strong word to describe old lanyards and that word should not be used to describe an organization. With available materials and the printing technology available today, dull-looking ID lanyards are now things of the past. So, good-bye, boring lanyards! Groups do not have to look boring anymore. Bearing the company color and logo, the ID lanyard can inspire a member or employee to feel like a part of something great.

With modern, colorful lanyards in wide use around the world, the even more boring piece of string or yarn was pushed into obsolescence as lanyard material. Of course, people can still go for an exciting set of bling or chains to hold an ID badge around the neck. But it is doubtful that chains can measure up to the practical and lightweight ID lanyards of today. Lanyards may not be as shiny as gold chains, but they will not give the wearer a stiff neck afterwards.

So, how can an ordinary group of individuals transform the traditional lanyard?

Organizations and businesses can approach wholesale lanyards suppliers. With today’s technology, these suppliers can sell a lot of lanyards for a good price. Along with the good price, the supplier can provide extras, like printing and other attachments. With the different kinds of fabric available, the supplier can even improve the quality of the printing process used on the lanyards.

Typical materials today include nylon, polyester, woven polyester, tubular lanyards, and dye sublimated kinds. All of these materials can last long depending on use. Each material has a unique advantage over the other. The suppliers can only provide one color for the material. Even if that is the case, the supplier can still give options for putting a logo or text on. The option changes depending on the kind of material used for ID lanyards. Suppliers can also use Pantone-matching to ensure customers get the correct color on lanyards every time.

Just to cite some material advantages, the dye sublimated lanyard can have the printing go deep into the polyester fabric. The advantage there is that the color stays fast longer than what the usual printing process can provide.

In the case of nylon lanyards, suppliers can make the text and logos appear like these were silkscreened. Having that style of printing makes the logos to have more detail.

In the case of woven lanyards, the difference lies in the finish. Groups may want to have an elegant look to go with the text on the ID lanyards. The woven material can give that.

Tubular material looks like an old tubular shoe string. That can also be a plus for a group that wants that kind of classic appeal. Polyester, of course, is durable and provides good value to the group. It can appeal to both the eyes and cash budget.

For the groups wanting to jazz up the lanyard, there are actually choices for attachments. Groups can choose between the free offerings and paid-for premium kinds of attachments. know more about different types of lanyard visit wholesalelanyards

When A SEO Agency Fails To Deliver – Things To Look Out For

Trusting someone to build the right marketing elements for your page is not uncommon. Millions of people move forward with hiring someone to build their campaigns for marketing purposes, and they do a good job overall, but there are some exceptions. There’s always going to be companies and individuals that will not deliver on the promise to give you a great deal of marketing collateral. In fact, you may find that you could end up working within the confines of a lot of conjecture, and that’s no good. If you’re dealing with a company that isn’t delivering on the promise of optimization, you are going to see things manifest that should guide you to walk away. Focusing on hiring a good SEO Agency is important, and that starts with looking into a few elements of marketing collateral. The following are just a few things that you should be watching out for, no matter what happens in regards to relationship with elements of internet marketing glory.

The Hiring Process

The first thing that you should look for when you’re going to hire a SEO Agency is whether or not they rush you through the process. If they are going to rush you through every little instance, you want to avoid them. You don’t want to get rushed through this at all, because if you end up getting pushed in this manner, you are going to lose market share over time. Focusing on the right elements here is a matter of grave importance. If you are rushed through the sales process, and you end up getting mediocre elements, it’s going to be apartment within the first few months of work. Visit URL to get the best deals of SEO agency options.

seoIf you hire someone for a limited time, make sure that you have a clear understanding of the deliverables that they are going to bring to you at the end of your term. Do not renew anything until you ensure that they have delivered on the promise of getting your site attention. Otherwise, you’re going to end up dealing with a lot of issues in regards to the outcome of your terms. Do not allow anyone to rush you through the hiring process, even if they claim that they have limited time pricing or anything like that. Take your time, look for an agency that can prove that they are doing good work, and then hire them.

The Traffic Margins Diminish

One way to ensure that you are getting helped with the right type of service is to make sure that you are looking at the traffic. Look at the analytics that you have and see whether or not you’re getting a push up the proverbial ladder. If you do not see a push at all, then there’s something wrong. It’s very important that you seek out elements of placement that are going to build on the sequence of traffic that you need to gain major elemental pushes. Do not end up with something that is going to diminish your traffic, especially if you see a huge spike.

If for whatever reason you’ve hired an agency and you start to see your traffic spike, out of the blue, you most likely have been penalized by search engines. When search engines dish out their penalties, they do so by closing off your traffic margins and forcing your indexes to drop out of the sky. This is not a good sign, and therefore, you should fire you agency fast.

Spamming Social Networks

Another way that you can denote whether or not the SEO Agency that you’ve hired is doing terrible work is to look at your social networking profiles. Look to see whether or not they are being updated, or whether they are getting updated with what is deemed spam. A lot of pages are getting nothing but spam, and that’s not a good thing. Do not allow yourself to get updates that are obviously spam, including link generation, spam bots and more. Always watch out how you’re working with social media and don’t let any agency take control to the point that you don’t have a say in what you’re posting. It’s easy to slip up here, don’t let it happen to you.

Focus on building the right kind of collateral, and focus on building friendships within social sites. Always focus on the building of the right kind of elements, so that you are able to gain leverage overall. You’re not going to get anywhere if you’re not working on optimization strategies that will help you build a great deal of market share. Spamming social media is not a good way to get anywhere with SEO, and it will only prove detrimental over time.

After it’s all said and done, you need to make sure that you’re reliant on a SEO Agency that has proven results. If they don’t have any proven results from the past, you’re going about things wrong. Always ask to see the credentials of a company, and work within the right parameters to get moving forward. It’s something important that most people don’t really think about until it’s too late. Take your time in the hiring process, and then keep up on what is being done in your brand’s name.

Things to Consider in Choosing Golf Equipment

Everyone knows that a golfer needs a golf ball and a golf club to play golf. However, not everyone is aware of all the things that should be considered in choosing the right ball and club for a game. There are actually a lot of things to consider for golf equipment but most players only find these out after a game. Here are some basic things that could help in finding golf equipment.

Golf balls
  • Purpose

golf ballWhen first starting to play golf, one does not need to buy golf balls of high quality. Though it may be a psychological boost to play using professional balls, this would not really affect a beginner’s performance in a game. What would most likely happen is that a player would keep losing his golf balls while he plays so it would be better to start learning the game using the standard golf balls.

For the beginner, the best golf balls to buy are the practice balls that are also known as range balls. This kind of golf equipment is made as cheaply as possible while still maintaining the level of quality required to pass the test of approval for golf balls.

There are also balls, called recreational balls, made for the regular golf player. These are also called standard balls. They have low compression and are able to reduce the side spins when hit; these features make it best for golf players with low swing speeds. These are also relatively affordable.

For the professional players, the best balls to be used would be the advanced balls. They prompt a greater amount of spin from lofted shots and work best when hit with great swing speed.

  • Player’s ability and level of desired flight and landing behaviors

There are three things to consider in looking for golf balls: compression, spin, and the dimple pattern. Compression is based on how hard the core layers are. A high compression ball will be propelled farther but will give the player a feeling of shock in the arms, dubbed as the hard feel. A low compression ball covers a shorter distance but does not give a shocked feeling in the arms.

Compression also affects the spin of the ball. A high spin ball prompts more backspin when hit, which could increase the travel distance of the ball. The opposite is true for low spin balls.

Golf club

These are perhaps one of the most expensive pieces of golf equipment that a golf player would buy during his career as a golf player. The golf club to be used depends on what kind of play the golfer aims to do. Golf clubs vary depending on the shape and style modified for different playing fields. There is actually no average golf club as clubs are fitted to match the person’s height and weight.

For those who enjoy watching the ball fly and cover the longest distance possible, the best type of golf club would be the Woods. Woods are built to utilize the maximum distance and speed of a golf ball, and are the most powerful and the longest of all types of clubs.

For golf players who like more control over their hit, irons would be the best choice. Irons enable a golfer to restrict the direction, spin, and travel distance of a ball. These are actually designed to let the player have more variety in his strikes. These are best used when the player is in the rough.

To have the long distance drive of the woods and the higher launch of the irons, golf players use a mix of the two clubs called a hybrid. Hybrids allow players to propel the ball at longer distance with a relatively slower swing speed.

Designs and Styles of Custom Challenge Coins

Custom challenge coin are considered to be prized possessions by its owners. Designed to be unique for each organization, every achievement, or occasion, they are without a doubt deserving of nothing short of perfection in its style, design, make, and material.

Today, there are a lot of companies who claim to make the very best challenge coins. However, only a few of these companies can deliver on what their customer wants. Designing for challenge coins needs highly skilled artists to conceptualize a design and minting it according to the client’s tastes. Being able to deliver on the customer’s demands is a very precise art.

The style that is imprinted on the challenge coinsis what gives it the“antique value” that makes it very valuable. It is the style and design of the coin the ultimately decides its very value. They can be made with brass for a durable and appealing finish. They can also be made with gold or enamel to make an elegant piece. But at the end of the day, it is up to the customer how they want their custom challenge coin to look like. With various design options at their disposal, the only thing that can limit them is their budget. Style and design potential is limitless, given the wild imagination of artists.

Custom Challenge CoinsCustomers can also tweak the coin’s edges and rims. There are two sides to a coin. The “heads” face or “obverse” and the “tails” face or “reverse”. The space between the two is called the “edge” and the elevated portion is called the “rim”. There can be a lot of work done to these parts that can only make your custom challenge coin even more unique.

If you want to make your own batch of custom challenge coin.

Here are some style and design notes that you may want to keep in mind :

1. Metal

This particular style of custom challenge coin look very appealing with its fine metallic sheen and bold look. Some material options for this style includes: polished brass, polished gold metal, polished silver, polished copper and black nickel. Sometimes a company would also offer more finishing options such as antique silver, copper, or gold.

2. Diamond cut edges

The coin can be customized to have cross-cut, wave-cut, black nickel, and oblique-cut edges, beautifully styling your custom challenge coin.

3. 3D design

This gives your custom challenge coin the depth for its design which makes it a very unique and memorable present or token to give to anyone.

4. Numbered coins (sequential)

This is another interesting option in designing your custom challenge coin. With this design you can have serial numbers on your coin so that the owners of the coin fall under a number sequence for receiving it, making it unique to the owner and allowing you to be able to identify which coin belongs to which owner.

5. Engraved text

This is and will forever be a classic. Having text engraved on your challenge coins leaves a majestic impression on the coin, along with the name of the organization or the recipient, or even a message engraved on the face of the challenge coin.
When designing the emblem that you want to engrave on your personalized challenge coins.

Here are some ideas that you may want to remember :

1. Try drawing multiple designs on paper first before sending the final design to the minting company

2.  Deciding on what metal/material you want to use for your challenge coins. See above.

3.  Conceptualize the artwork. How would it look like? What would be the theme? What colors are you going to have on your coins?

4. Choose a proper and suitable edge for your design.

5. Choosing what enamel finish would bring out the best in your coins.

6. You can also draw up plans for a beautiful coin case or display as an additional option to make it more presentable.

Buy top quality research chemicals to avoid backfires

Conducting experiments is very expensive because the instruments, test kits, and equipment needed could cost up to tens of thousands of dollars. Samples can also vary, from those that can be easily obtained in your backyard up to those that can only be obtained in the deepest parts of the sea. Devices that can help analyze your data are also costly. And of course, the research chemicals you have to use in every step can cost from hundreds to thousands of dollars. Hence, scientists should always be really careful, precise, and accurate in order to avoid wasting resources. They should also pay attention to the reagents and solutions they are going to use in order to prevent repeat experiments that are caused by bad or contaminated chemicals.

research chemical

Bad reagents are those contaminated ones, those that have formed weird precipitates, have turned into an unexpected color, or have drastically changed their pH. These can cause an experimental failure either in the middle or at the end of a research study, which is a very huge loss for both the researcher and the laboratory. Time, money, sweat, blood, and tears are all wasted due to a very undeserving cause. If this is the only reason as to why one should buy research chemicals from trusted suppliers, then it is all worth it. A lifetime’s worth of hard work and a billion dollars’ worth of ideas may all be depending on these chemicals anyway.

In order to buy research chemicals that are of high quality, one should consider manufacturers and suppliers that have superior standards. They should also be boasting about manufacturing and selling certifications and licenses. Their high quality reagents and solutions should also be proven and tested by more than one independent research group, and their descriptions and specifications should match their products’ function and performance.

research chemical2

Having good research chemicals in the laboratory can assure researchers and scientists that their experiments are running on a good gas that can last for months to years and that can accommodate a dozen different experiments at once. Moreover, if scientists opt to buy research chemicals that are of high quality, they can be assured of stable products that will not degrade easily, even with fluctuating pH and temperature. Not only are those products helpful during various experimental conditions, but they can also be salvaged if that one-in-at-thousand chance happens wherein something goes wrong with your storage equipment.

Other examples of drastic effects of bad reagents include getting the wrong numbers and results during analytical procedures, obtaining the opposite of the expected outcome, and very high standards of deviation. In microbiology, your desired bacteria may not grow well in your prepared media or it will take a longer period for it to grow. It may not even totally appear or a completely different species, such as undesirable molds and yeasts, would grow instead. In molecular biology on the other hand, your DNA and RNA extraction protocols could totally fail. Either you will get a very insignificant amount of nucleic acids, an impure product, or you will not get anything at all. The same can also happen in chromatography. You will not be able to isolate your desired product or still get an impure even after a long and tedious process.

Bad research chemicals can be avoided by simply taking a closer look at what different suppliers have to offer and also by being really careful during the reagent preparation step of every experiment. You must also be ready to spend some cash in order to get and buy research chemicals that will satisfy all your needs.
