How ac/dc power supplies save you money
Choosing a high-quality, high-efficiency power supply that costs $50-$100, will probably pay for itself in the course of a year. Today’s trend is for power supplies to do more, have more, but cost less. Engineers that use power supplies are seeking less expensive supplies with additional features, while maintaining the same amount of energy needed […]
Three common mistakes when designing power supplies
When I posed this question to companies that design power supplies, I thought that I was going to receive varying answers. Surprisingly, these companies tend to agree on the biggest mistakes that engineers/designers make in designing in-plant power supplies. For the purpose of this article , I have used specifications from a common ATX12V Power […]
Engineering and Concussion Reduction Therapy (CRT)
There has been a lot of discussion about aggressive sports and head injuries. These conversations are pertaining to the rising concerns of traumatic brain injuries resulting from forceful hits in contact sports. For males, football (US) is the most common sport causing concussions; while for females, soccer (US) is the most common sport. Over the […]
Update: Student loan forgiveness for Engineers
Don’t despair! We are getting close to a loan program that will help all engineers. Hold on to your hats kids. I went online to pay my student loan bill and observed that my loan service provider recently added the Public Service Loan Forgiveness program to its loan forgiveness list. What does this mean? This […]
The biggest engineering mistakes / disasters in modern history
Over the course of history, man has made plenty mistakes when inventing devices to better mankind. Some mistakes were miniscule mishaps that resulted in huge disasters. In this list, I have compiled some of the biggest mistakes/disasters engineers have made in modern history, in no particular order. I chose not to list mistakes that are […]
Video: What are Digital Systems? (Part One – The AND, OR, NOT gates)
This is part one of the basics in Digital Systems. Beginning with the existence of Boolean Algebra, take on the form of “true” and “false”. This area of thought process is called “Deductive Logic”. This presentation explains the three most common gates, its meanings and how it relates to Boolean algebra. The fundamentals to Digital […]
