  • Gadgets, Tips/Advise Comments Off on The Evolution Of Electrical Safety

    Looking back at the days when power lines were just starting to appear at the roads and streets of Indiana, the electrical technology has evolved in so many ways since then. In the early days of electricity, it was not imagined and even envisioned by majority of the consumers that electricity will have such a big impact in people’s lives. Nowadays, electricity is helping us love our day to day lives by powering up our daily machines such as LCD televisions, air conditioning system and computers, among many others.

    According to the CEO of IEC or Indiana Electric Cooperatives, Rick Coons, along with the changes in electrical technology, electrical safety has evolved over time as well. Practices that were commonly exercised decades ago are now considered in the present time. The major reason for this evolution is because electrical technology has also changed and improved. Another reason is that humans now have a better knowledge of how electricity really works.

    Let us just look at the changes in terms of home wiring. Coons shared that in the very beginning of IEC wherein they are just starting to connect homes with wires the company uses ceramic knobs as well as tubes because these are then considered safe. Connections are just left exposed and there proper grounding was not practiced. Nowadays, no one will dare to wire a home in such manner.

    People who knew about this practice and got used to them are not aware of the danger they pose. Coons added that majority of improvements that concern home wiring and the electrical safety it entails were made because of the existence of the problems that were present in the wiring styles of the early days. It was in 1894 when Underwriters Laboratories was developed by insurance industry in order to create a standard practice when handling electricity and the decrease the risk of fire. Three years later, the national electrical code was the first to be adopted by the public.

    Electricity is evolving to be safer and safer as the years pass by. These codes are used as a guide by Gold Coast Electricians to make sure that the old fashioned way will no longer be practiced for the safety of homeowners.

  • Gadgets, Tech Comments Off on The 7 Basic Tools That Every HVAC Student Should Have

    March 29, 2016 – The Heating, Ventilation, Air Conditioning (HVAC) System is an important part of any establishment as it is mainly responsible for making the living environment habitably comfortable for the people staying inside. For example, in a business establishment, the HVAC system can help make the offices and working areas livable and comfortable for the employees and workers to function well. In a household, the same application goes as the HVAC system is responsible for helping you feel as comfortable in your own household as you can be. For this reason, many people invest on maintaining their HVAC systems that is why a career in HVAC can be lucrative.

    If you’re planning to become an HVAC technician, you would have to enroll yourself in HVAC schools or courses where you’ll learn about HVAC repair, maintenance, and upgrades among many others. But even if you’re just a student, you would also be required by the school to possess the basic tools needed for HVAC. These tools go as follows:

    1. Safety Glasses. It is obvious why such an item is needed. You need to safety glasses to protect your eyes from certain particles that might irritate or even damage it. When you go out looking for glasses, make sure you consider the lens coating and color and the different categorization of safety glasses.
    2. Work Gloves. Work gloves protect your hands during risky applications like sheet metal duct installation.
    3. Digital Thermometer. This tool is both needed in school and while you’re on the actual job. There are many different types and brands. Make sure to find one that you’re comfortable using.
    4. Screwdrivers (Flatheads and Phillips). Every HVAC school would require this but it is up to you if you would like to buy a set or not.
    5. This is also another tool that is required by schools. Some schools would require all needle nose pliers, lineman’s pliers, and tongue-and-groove pliers.
    6. It’s up to the school to decide which type (volt, Ohm, amp meter, or combinations) of voltmeter they would require.
    7. Wrenches (combination set or crescent). These tools are important in HVAC applications and are deemed a necessity. All schools would require you to possess a wrench as it is needed to turn or adjust an object such as a nut or bolt.
  • Many people are attached to their mobile phones that researchers are trying to figure out a connection that can tell about health and mood. In fact, a phone may be able to tell whether its owner is depressed and this seems to be better that self-assessment. This is a new study that was published in Journal of Medical Internet Research.

    According to David Mohr one of the authors of the study and director of the Center for Behavioral Intervention Technologies at Northwestern University Feinberg School of Medicine, the more that people spend with their phones, the more likely that they will become depressed. Researchers also found out that spending lots of time at home is linked to depression and phone data could predict with 87% accuracy if someone has symptoms of depression.

    28 people ranging from 19 to 58 years old were recruited by Northwestern researchers from Craigslist and integrated location and usage monitoring software on their smartphones. At the start of the study, the subjects took a standardized questionnaire that measured depressive symptoms and the results revealed that ½ has symptoms of depression while the other half did not have any. For two weeks, the phones tracked the GPS location information every five minutes and pinged the users with questions regarding their mood several times a day.

    The phone data that were collected by the researchers were rich and it included information like the places the participants visited each day, the amount of time they spent in the places visited and how often they used their phones. The researches collated the data with the depression test scores. One of the things that researchers found out is people do not answer questions. They may respond for a few days and then get tired of it.

    People who tend to spend more time in just one or two places are more likely to have high depression scores. People who stuck to a regular pattern of movement tend to be less depressed. The data that was derived from the phones were very useful in tracking depression without the need for the user to report what he is feeling. This is usually the barrier to depression treatment.

  • Technology has become an important part of daily life. People who make software are the new celebrities and rock stars who are forging the path ahead for modern web. The first generation of computer scientists who developed the internet came from the academia but today, there is a new wave of programmers who do tons of work behind the scenes to make the internet safe, secure and lot more fun.

    1. Online she is “ladyada” but she is actually NYC-based MIT graduate Limor Fried who develops software and hardware for electronic products and projects all over the whole world. In 2013, Fried told Newsweek in an interview that the company has received $22 million in revenue.
    2. Facebook bought Oculus for $2 billion. The founder of Oculus VR is 22 year old Paler Luckey who will be lucky if virtual reality takes off like Facebook.
    3. Depression Quest is an award-winning game that was developed by Zoe Quinn but after being the target of an online harassment campaign, Zoe and partner Alex Lifschitz started on Crash Override which is an anti-online hate mob task force that builds software and tools to stop online harassment.
    4. Another victim of online harassment is Brianna Wu who is the co-founder of games studio Giant Spacekat that made the game Revolution for iOS. After experiencing online harassment, Wu became an outspoken advocate for equality in technology-related fields.
    5. Mitchell Hashimoto is a 26-year old co-founder of HashiCorp that develops programmer productivity software for customers that include BBC, Mozilla, Nokia and Yammer.
    6. Parisa Tabriz is 31 years old and holds the title of Google Security Princess meaning that she is the tech giant’s hacker in residence to figure out flaws in software.
    7. Sara Haider is an Android engineer at Twitter-owned Periscope and is best known for leading Twitter’s Android app.
