Virtual outsourcing, virtual assistants and virtual logistics can provide your organization with Engineering knowledge and support at a better overall cost than hiring new employees. Virtual outsourcing is the process of hiring an outside consultant who will provide the professional services you need and usually will provide these services working remotely from any where in the world.
More specifically your business should consider and can save a lot of money by outsourcing the following tasks.
Database management & data entry
Data manipulation & automation
Online research and automated online BOTs
Marketing material, blogging and social networking
Customer relations management
Customer service and chat support
Managing your calendar, appointments and flight reservations
Recruiting new employees
Accounting and bookkeeping
Business process analysis and improvement
CAD design and code development
Virtual site evaluations
Product development and new product design
Searching for suppliers and fabricators
3D Prototyping and manufacturing
Your website hosting service may not be cutting it. Is it time to move to a new host? Most services claim that they can provide 99.9% up time but is it really true. Even some of the best server hosting companies are not meeting their claims.
Shared web hosting today is not the same as it was in the early 2000s. Back then you were not hosting your website on a single server that have more than 1000 customers. It was more likely to purchase a very cheap shared hosting plan with less than 100 websites on one server. Shared hosting plans are a great start for developing a website but in the long run they will never be able to handle even basic traffic. And to top that off most of them are battling down time and server abuse. Now a days there is so much more scamming and…
So I wanted to briefly blog about my first experience with market.Envato.com products. Envato is an online place to buy themes, plugins and code for website design. They are a giant in the market and are a subsidiary of ThemeForest.net. They began around 2006 and grew into a giant in just a few years. This blog is not to explain who or what they are. There are many places you can get more information about this company based out of Australia.
Well lets get down to business. What I found is they do not support what they sell nor do they offer much in terms of credits for downloading broken themes or bad code. We are just one in thousands of blogs that have had the same experience with buying a product from their website and hoping it will save time. Its quite the contrary because you will end up…
After years of coding websites by hand I decided to move into buying themes. To speed up the process of developing websites html templates really saved a lot time back in the day. But today I am specifically talking about WordPress theme templates.
As a professional coder for over ten years it exposed me to more than 20 programming languages. Today there are so many different platforms and programming languages that an experienced and well rounded computer scientist is someone who is really a bilingualist.
The purpose of this blog is to prepare clients and newbys when they decide to purchase WordPress themes online. What I found is templates can contain serious bugs enough to really cause major down time and complete failures of websites. Keep in mind WordPress itself is a very stable platform. A lot of people want to blame WordPress when a buggy template or plugin fails…
As a developer for private organizations I started to really understand the distribution network currently available for developers online. It consists of several large players. They include Mojo Themes, Elegant Themes who does not use third party distribution the right way to do it, Authentic themes, Graph paper press, Press75, Aliewp and then there is a group who are all basically the same company. This is the largest player of them all, the Envato Market which consists of themeforest, codecanyon, videohive, audiojungle, graphicriver, photodune, 3docean and activeden. The Envato market is somehow related to each of its partners which is not always clear but business policies are inherited in some form or another.
So you are developing new code for some application such as WordPress or JoomLa. Your code works great and you want to provide a very reasonable price with excellent support for your customers. I bet the first…
The job market today has changed dramatically. Corporations are looking for better and cheaper ways to hire new employees. But is full time employment the most efficient way? Lets discuss a few reasons why hiring professional consulting firms can grow your business faster than hiring employees.
First lets talk about how much value an engineering consulting firm can bring to your business. A professional engineering consulting firm is going to have a great deal of engineering knowledge that you could not achieve from a single employee. No matter what your hiring process is no testing or extensive interview process is going to determine if the new hire is going to perform to your standards. Its a fact that many people lie on their resumes in order to land the job and most people are just not cut out for the position.
When you hire employees the…
Geo Blocking – Does it really benefit your organization? Do you really want to block possible global opportunities?
We have noticed a great deal of corporations who feel it is necessary to Geo Block their web domains. For example lets discuss a well known website. Loopnet.com is a very popular commercial real estate website in the United States. They made a corporate decision a few months ago to block most of South America and other nations from accessing their site.
In most cases Geo Blocking is for security problems and price control this is the reason why Geo Blocking really started but maybe you do not realize there are literally millions of American citizens living and working outside of the United States who either own property in the United States or are looking for property in the states. Some are looking for commercial space in the states for branching a…
World Fuel Costs
Did you know that we pay as much to fuel up our vehicles in two years as the value of the vehicle. This happens almost always with SUVs and trucks and is becoming more of a reality as the price of fossil fuel more than triples. Did you know that many nations we import fuel from sell fuel for less than the cost of water!
Europe does pay more for fuel than the United States but they have a very different lifestyle that allows for higher prices. The United States is a big place, especially Texas. Our commute and driving is more than double the European lifestyle. Public transportation is poor in many states which makes us rely on fuels for transportation more than most nations. Comparing our fuel prices with higher prices in Europe is a poor comparison and only leads to excuses and barriers to…
Fuel Cells and Natural Gas
The practicality of fuel cells is years away. The supply of fuel cells is small and the technology is so expensive that it would costs enormous amounts of money to build a fuel cell vehicle that was in any way practical. One of the other downfalls is you still need fuel and the infrastructure of fueling stations is non-existent.
Fuel cell vehicles will take some time to enter mainstream or they may never enter mainstream at all. We may be involved with the development of the fuel cell but for now we stick with what is practical, cost effective, works well and is past the proof of concept stage. Most people like the fact that electric vehicle technology eliminates their dependence on any kind of fuel. The use of natural gas will mostly benefit heavy equipment and trucks.…
We do not actually make any fuels. We can provide clients with the skills and knowledge they need in order to make bio-fuels or run straight vegetable oil. Biofuels are typically used in place of petro-diesel. Any diesel engine can accept bio-fuels. Actually the diesel engine was designed for bio-fuels. Since producing electric engines to drive large trucks and heavy equipment is currently not very practical, bio-fuels are becoming mainstream in trucks, buses and heavy equipment as an alternative fuel source. Bio-fuels are generally cheaper to make and can be better for the environment if properly used.
straight vegetable oil
steel frames and anti-static tanks
thick wall high density polyethylene thermoplastic welded tanks
stainless steel tanks
Bio-diesel Main Ingredients
straight vegetable oil
waste vegetable oils
waste cooking oils
biodiesel is cheaper than fossil fuels ( petrodiesel )

The migration to paperless operations varies for many organizations. Its astonishing how many large organizations are not paperless in 2015. The problem is paper trails for older organizations are long and sometimes full of holes or business processes that continue to require a paper trail. In South America its even worse. Paper trails in large organizations in South America and developing countries are destroying customer service. In fact paper trails in South America are so bad that if someone looses a receipt they could be out of a product warranty or replacement even if they paid for the service. We are in 2015 where smart phones can do just about anything and still even cell phone providers are using paper everywhere. Paperless is something we specialize in and its a very important part of the growth of an organization and with proper planning any business process can migrate into 100%…
There are many aspects to the security of websites let alone the security of your PC. Lets discuss some of the reasons you would want a secure site and then some of the reasons why more advanced site security is really not that necessary.
TYPE OF SECURITY
First of it really depends on what you intend to store or what kind of transactions your website is going to perform. For example online shopping may be storing credit card information. In this case site security is a must. Most online shopping will store the credit card information for short periods of time during a transaction or pass this information from PC to server. But usually this information is removed and never stored in the database. The reason being because most hackers are trying to get into the main database and find the most critical information. What they want is customer information…
A mobile app runs on the mobile phone platform creating a user shortcut and an interface that has been optimized for the mobile device that is being used. It then can access the same content that you would access using a website. There are benefits and drawbacks but the main thing a client should think about is trying to make a website at least hybrid mobile friendly.
If you are planning on mobile app development you should talk with us about the benefits and drawbacks to mobile apps. In most cases a mobile app can provide a great benefit for the business but in some cases a responsive website will be enough to market your product and services.
Keep in mind there are many applications and situations where mobile just does not play a role because of the size of the devices and the lack of user interface. However, this…
The United States continues to struggle with global competition as colleges continue to raise their prices for science and high-tech engineering degrees. What most students and engineers do not realize is most of the world is designing and developing complex engineering projects at a fraction of the cost. Students are receiving the same education abroad and working for a lot less and producing the same quality work.
By hiring consultants abroad Corporations are focusing on reducing costs and increasing profits which is easy to do today. Lets take a look at some of the current numbers in the United States and compare them with Latin America. Keep in mind these costs are averages. It does depend on the project, experience and if the engineer you will be working with is fluent in English. In most cases hourly in Latin America is considerably lower than the prices found in the comparison…
3D printers have the potential to change the world in a drastic way. They can eliminate the need for shipping companies, completely change the logistics of our world today or open up a whole new world of innovative brands and new product design.
Today you can actually pick up a decent small 3D printer for around $1000. A small price to pay for what it can actually do. But lets imagine the future 3D printer. This is a printer that can do a lot more a lot faster a lot bigger and with higher quality plastics.
Remember all those sunglasses you had that broke because they were made in China and the plastic was of faulty quality. Well imagine printing as many sun glasses as you want using your own 3D printer. Any style, any color and with much better overall quality. That is just a very small example of…
The development of cellular phones took portable to a new level. Mobile devices are now an extension of laptop computers with a lot more benefit. Mobile devices give us the ability to expand social networking into our every day lives.
But what about connecting at a more cellular level. How about wearing the technology or even better implanting it into our bodies. Well the first step is of course wearable. We will integrate the internet of things not only into our daily lives but also into our bodies. This already started with the development of bluetooth devices for your ear and now smart watches that communicate with your cellular phone.
But what does the future really hold and how soon? Already ocular and inner ear implants exist and work. Cellular phones have reached their limit in terms of portability and accessing information. I mean whats next other than a flexible…
One of the most important courses to prepare future engineers that should be required for high school students across the United States is some form of three dimensional computer aided drawing. Just as typing was a requirement in the late 1900s there is no denying that we are now in a computer aided world. High school students time and time again are learning skills that are decades behind the times. Students are still writing and printing documents which are skills that will slowly but surely fade into history.
Students who want to become engineers are not properly prepared for college or the real world. Skills such as basic programming, typing, calculus and three dimensional CAD should be learned well in advance before any college engineering program. The ability for students to communicate ideas through advanced drawing programs through their PCs will better prepare them for higher paying jobs and more…
Now that we our lives are global, more and more businesses are seeing the benefits of having a virtual office. These benefits consist of reduced operational cost, happier staff and increased production. We work remotely and we are proud of it. A lot of companies would disagree that hiring consultants who work remotely is a good idea. They complain its too complicated or there will be a communications breakdown. The truth is remote work is growing faster than large corporations can keep up with.
The concept of remote operations really started with call centers back in the 1990s. A lot of which were based in India. Call centers started to prove that entire operations for one organization could be hosted outside of their home country. This would enable corporations to reduce labor costs and work with other countries who can add value and services that might be too expensive in…
The most important FCC vote of our lifetime is about to happen! The Elimination of “Net Neutrality”
On Feb 26, 2015 the FCC will vote to save “Net Neutrality” or let Comcast and other ISPs create Internet slow lanes. Some members of Congress, on behalf of their Cable donors, are trying to stop the FCC from protecting the Internet we love.
So lets discuss what is net neutrality and how it will effect small business and large businesses. Currently we live in a net neutral world. Everyone was a start up at one point. Netflix, Facebook even Google all had the opportunity to grow because of net neutrality. Basically net neutrality gives everyone a level playing field on the web. Whether you are starting a new business and want to start a new company website net neutrality essentially lets you do what you want without any taxation or throttling down…

As many have probably noticed we are based out of Dallas, Texas but also have an office in Lima, Peru. South America was a first choice to place a second office outside of the United States and there are a number of reasons why.
Most people have misconceptions about South American countries. People think countries in South America breed dishonest business practices. Economies are not balanced and technology is lacking. Third world is usually the name given to most countries in South America.
However, in the last decade since we have been working and traveling here things have changed tremendously. Technology has advanced rapidly, middle class has grown at an enormous rate. Businesses are learning that professionalism, honesty and global connections is what makes them grow. Access to products and services may have been a problem a decade ago but today we find that whatever exists in the United States…
Do firewalls really work?
This blog explores the growing problem of institutions blocking educational tools and other internet features. Institutions are being held more liable for inappropriate content and conduct through the internet. The problem is the laws being put in place protect institutions but in turn reduce students exposure to critical digital skills.
Why block the internet in the first place?
It is completely ineffective and wasting tax payers money. We have worked with students in several institutions. We are a hi-tech group and are well aware of ways around fire walls. This blog is not a tutorial on how to break through a firewall but we will point out that it is very easy. Students make comments that they know more than adults and teachers about the internet which unfortunately is true in a lot of institutions. Hacking through firewalls is as easy as pouring a bowl of…
A simple discussion of why internet service costs in the United States keep going up not down and I am not talking about broadband speeds.
The United States invented internet but that does not mean that we pay less for it than the rest of the world. As a matter of fact we are paying more to have a basic internet connection than most of the developing world. Cell phone plans are also becoming more expensive with very little options for low prepaid or rechargeable accounts.
Has the monopoly of telecommunications taken over the United States? Are we going to continue to pay more for communication services than the rest of the world and still lack access to very high speed internet? Will we fall behind on speed vs. cost?…
Did you know that debugging code is twice as hard as writing code! Especially when you are debugging code that you did not write. A lot of our clients ask us why it takes so long to debug something. The answer is debugging is a very tricky and lengthy procedure. It requires us to dig into code that we did not write. In any case the code might be well written or as in most cases it is poorly written. Here others can share thoughts on debugging code that was created by another developer.…
Professional Freelance Engineers are the new engineering consultants of the 21st century
Freelance engineering has been sometimes been associated with job drifters. People who drift from one job to another without being able to hold down a particular positions. However this is quite the contrary. With the advancement of computers, faster internet connection, outsourcing and remote project management Freelance Engineers are now becoming very successful and very useful to organizations. They provide powerful knowledge and unlimited resources that corporations never could access before. Most people do not realize how much software is being developed in India by freelance engineers for the United States. Its nothing new and only growing faster as we gain access to much faster internet speeds.
What is a freelance engineering consultant?
A ‘freelancer’ or ‘freelance worker” is a term commonly used for a person who is self-employed and is not necessarily committed to a particular employer…
Out with the old in with the new
Buying a 100% electric vehicle can raise many questions. Where do I service them, how do I charge them, how many miles can I drive, what do they cost? We do not design or work on hybrids or series hybrid vehicles, only futuristic vehicles which are pure electrics and contain much more intelligence than vehicles today.
Electric vehicles are low maintenance cars with long lasting engines that require very little service. As a matter of fact electric vehicles contain 60% less parts than gasoline and hybrid engines. In the future electric vehicles could drastically reduce revenues for corporations who continue to manufacture inefficient ICEs (internal combustion engines). Their are several reasons for so few electric cars on the road today which do NOT benefit the consumer.
Reduced vehicle maintenance could reduce corporate revenues
Longer lasting vehicles would mean less new vehicle sales…

Many electric vehicle charging stations were installed across the United States during the green boom between 2008-2013. Government incentive programs paid for companies to install charge stations in select locations. The problem is people are not using the charging stations as much as was expected. The cost of charging you car at a charging station is much higher than at home which reverses any savings by buying an electric vehicle. The big question is who is really using charging stations and were all the installation worth tax payers money?
Vehicle system upgrades
Charge station integration
Vehicle range upgrades (truck and automobile)

Not too be confused with solar hybrid lighting and solar electric systems. Solar thermal is a technology for harnessing solar energy for heat. Solar thermal systems are generally used to heat swimming pools and create hot water for residential and commercial use.
Solar thermal systems come in several forms. Batch/ICS, thermosiphon, open loop, closed loop, drain back and closed loop glycol. The closed loop glycol systems are by far the best in performance and will work in all climates. Because of this flexibility these systems tend to be higher in price than the others. System components consist of a glycol fluid pump, expansion tank, relief valve, drain valve, anti scald valve, air vent, water heater tank, solar storage tank and collectors. Solar thermal pool heating setups and commercial setups are a bit different and will require different components.
For more information on solar thermal systems feel free to contact Dexa…
Photovoltaics / Solar Electric Systems
Photo is Greek for Light and Voltaic is after Allesandro Volta pioneer in the study of electricity. Thus photovoltaic means *light to electricity*. The photovoltaics (PV) convert sunlight directly to direct current (DC) electricity by use of a semiconductor.
Solar cells are made from a chemical element called silicon. Silicon is one of the most common substances on Earth and can be found in most semiconductors/integrated circuits today.
A semiconductor p-n junction produces an electric field that is maintained purely by virtue of the material. In other words, no external voltage need be applied. For a solar cell, this means that when light hits the cell, electrons are bumped from atoms and drawn to one side of the junction by the internal electric field producing a current. When current flows you have electricity.
Silicon PV comes in many varieties. Shell PV panels are made with…
After years of relative stability, oil prices have dramatically fallen. The end of the year 2014 and into the year 2015, in just a matter of six months oil literally collapsed below 50 $ a barrel.
Despite the fact that crude oil and solar energy are not direct substitutes, solar stocks are under performing drastically as a result. Oil companies are loosing profit and laying off as many as they can as fast as they can. With oil so cheap renewable energy is really not a concern for people. It has truly dropped off the radar.
So the question is why is renewable energy so dependent on the oil price? Is it possible to decouple oil price and solar development? What is to be expected for the coming future? Will oil prices skyrocket again?
Perhaps this is a business tactic, a way for Saudi Arabia to bring the price of…
Below are some common questions about solar energy systems. I have provided a basis for this blog. What I really would like to hear about is all these free solar systems that people are financing. Do you think financing solar is worth it and does the payback really make any sense? Are the companies who are locking people into these long term contracts telling them everything they need to know?
Can solar run a refrigerator, microwave, freezer or washing machine?
Yes. These appliances can take many watt-hours but only a few hundred watts. You can purchase high efficiency refrigerators, microwaves, and washing machine motors to minimize their energy use and benefit more from your solar system.
Can solar run a hot water heater or heating & cooling system?
For houses a more cost effective solution is to use another energy source for these items. Electric resistance heating such as an…
For those of you that are building custom electric vehicles. Here is a little blog about some of the platforms for a custom electric vehicle. Their are several very stable and economic high quality platforms. A platform can either be a brand new vehicle, a recycled used vehicle a production vehicle or a high end vehicle kit. Used vehicles are stripped of their internal combustion engines and replaced with an electric drive train. A platform does not have to be a production car and in many cases is not a production vehicle at all. Platform vehicles give the option of single or fleet vehicle production.
Designed for long range and high performance this type of EV is the highest in its class. All electric drive trains with high end flashy sports platforms.
Both high performance and longest ranges
50-250 mile range
0-60mph in less than 8 seconds
Below are some of the lead acid batteries that we have worked with for more than ten years. When it comes to storage options today the cheapest most practical is going to be some form of lead acid or AGM.
Keep in mind that Interstate Batteries is only a distribution brand nothing else. They have branches across America but a majority of their batteries are manufactured in China. We started to buy batteries more direct from China and find that many of the batteries China can offer directly are just as good if not better than the interstate u2200 or trojan T-105. Interstate batteries has many online distributors who get payed very little to resell their batteries. Some are legitimate and others are only advertising.
The next time you are thinking to buy a battery do some research. There are alternatives to the main stream batteries that are being sold…
Charging an Electric Car
The charging system in an electric car has two goals which consist of pumping electricity into the batteries as quickly as the batteries will allow and to monitor the batteries and avoid damaging them during the charging process.
The most sophisticated charging systems monitor battery voltage, current flow and battery temperature to minimize charging time. The charger sends as much current as it can without raising battery temperature too much. Less sophisticated chargers might monitor voltage or amperage only and make certain assumptions about average battery characteristics. A charger like this might apply maximum current to the batteries up through 80 percent of their capacity, and then cut the current back to some preset level for the final 20 percent to avoid overheating batteries.
Many electric cars actually have two different charging systems. One system accepts 120-volt or 240-volt power from a normal electrical outlet. The…
