Pspice Lab Series Video 3: Moving The Reference Ground Around

Zero volts reference, also known as ground is always a confusing topic. What if ground is placed at different locations in a circuit? In this 11 minute and 42 second video I use PSpice to show what happens when you move a ground around in a series circuit.

Want to learn more? I’ll be teaching a Systems 1 course online in the fall and a Systems 2 course in the spring at Holyoke Community College. If you are anywhere in the world and interested in taking an online course with me drop an email to gsnyder@hcc.edu Both courses will transfer to most university electrical engineering programs in the United States. Hope to see you there!!

PSpice Lab Series Video 1

Over the summer I’ll be working on a series of OrCAD PSpice videos. PSpice is one of the most common analog and mixed signal circuit simulator and verification tools used by electrical engineers to rapidly move through the design cycle, from circuit exploration to design development and verification. It is also a lot of fun to play around with!

I’m developing a series of 25-30 online experiments that we’ll be using in my EGR223 - System Analysis (Circuit Analysis 1) and EGR 224 - System Analysis (Circuit Analysis 2) courses at Holyoke Community College. Here’s the first video in the series.




OrCAD has an excellent academic program that provides students and educators with a complete suite of design and analysis tools to learn, teach, and create electronic hardware. If you are a student or educator you can download the software here for free and follow along with my labs. If you are not a student or educator (or perhaps considering) you can download and install a trial version of the software here.

STEM Studies: The Future of Engineering

Lauren Wilson,  Director of Admissions at Florida Polytechnic University offered the following as a guest post. I hope you enjoy it. Thanks Lauren!

New developments in the field of engineering owe a large debt to engineers with degrees from the fields of science, technology, engineering and mathematics (STEM). These developments are making huge strides for organizations across the board, but the environmental, medical and manufacturing industries in particular. Here are four examples.

3D Printing
Prototypes are a key part of turning a concept into a final product, but creating one was labor-intensive before the advent of 3D printing. 3D printing allows mechanical engineers to put their imaginations to the test and build 3D visual representations much faster than physical prototypes. In addition to speed, 3D printing is also more cost-efficient and easier to use than physical prototyping.

Nanotechnology
Nanotechnology is changing the way mechanical engineers work by opening up the possibility of manufacturing devices on the molecular and atomic level for custom applications. These devices, which are designed to reduce weight, volume and power demands, carry the added benefit of greater sustainability.

For example, a nanotechnology engineer may work in the environmental industry testing different pollutants in the world’s food supply on the cellular level. Successful research would reduce these pollutants on a nanoscale and lay the groundwork for a more sustainable future.

STEM-focused curriculums provide an advantage in nanotechnology, because students work with cutting-edge technology to find solutions for real-world challenges. STEM universities also quickly adapt to industry changes to ensure best practices are taught for creating these materials.

Grid Decentralization
Electrical engineers focus primarily on up-and-coming fields in the engineering industry, including grid decentralization. Grid decentralization is gaining popularity from Colorado to Denmark as a way to reduce the environmental impact created by its communities. Unlike conventional power stations, grid decentralization technology uses renewable energy sources like solar and wind to create power. STEM studies have helped cities and countries transform the way they collect power by thoroughly covering topics ranging from micro-grids to “smart” grids. More importantly, these studies put creative power directly into the hands of students with hands-on projects, internships and real-world challenges. 

Lean Manufacturing
Lean manufacturing has dramatically reshaped the roles of industrial engineers over the past decade. Driven by STEM studies, lean manufacturing is focuses on eliminating waste from production processes to create a more agile system. With a primary focus on making systems more sustainable, faster and cost-effective, industrial engineers developed this principle based on studies in STEM subjects including: multifunctional materials, nanotechnology, supply chain logistics, Six Sigma and system analysis. 

Universities offering industrial engineering degree programs take a pragmatic approach to learning in the classroom. Students can expect to concentrate on applying the principles of design, analysis and manufacturing to real-world challenges to improve mechanical systems.

Artificial Organs
Biomedical engineering fuses engineering principles with biology to build life-saving medical technologies such as artificial organs. Although biomedical engineering has had a long history, the most recent groundbreaking technologies are a result of advanced education in STEM subjects. Artificial hearts and iPills, for example, are two biomedical engineering breakthroughs that have restored hope for critically ill patients. Biomedical engineering students in STEM learn how to develop and maintain improved medical systems, and perform research on artificial organs, implanted devices, prosthetics and radiation therapy.

STEM focuses solely on the four subjects used most frequently by engineers, and it essentially guarantees that more breakthroughs and improvements are to come. With the help of a STEM education, engineers can apply best practices for reducing energy consumption, minimizing environmental impact and increasing efficiency. From 3D printing to nanotechnology, there’s no denying the future of engineering is bright and full of potential.

ATETV.ORG - Thinking About A High Technology Career?

If you or someone you know is thinking about a career in a high technology field, you need to take a look at Advanced Technological Education Television (ATETV.ORG). There, you'll find a National Science Foundation funded Web-based video series and interactive network designed to connect students and professionals with careers in advanced technology. The series highlights ATE success stories from community colleges and ATE programs nationwide. Its outreach efforts -- at ATETV.org and on social networking sites like YouTube, Facebook and Twitter -- aim to connect employers in industry and government with the high-tech workforce of tomorrow.

Here's the third episode in the series, featuring how The College of the Mainland trains students on an industry-scale oil refinery and how schools are working to close the gender gap in biotechnology. Be sure to check this one out along with all the episodes on YouTube and grab them on iTunes.



A little more from the ATETV website....... globalization has changed the scope of our workforce, creating new opportunities and greater demand for workers in the fields of science and technology. In order to drive our economy forward, we must recruit, train and place technically skilled professionals to meet new demand.

How can you get involved and learn more - check out ATETV.ORG and your local community college!

President Bush Signs H.R. 2272 COMPETES Bill

On Monday I here wrote about the H.R. 2272: The America Creating Opportunities to Meaningfully Promote Excellence in Technology, Education, and Science Act (COMPETES) bill. Well.... before heading off for his one-month vacation - President Bush signed it today! Here's a couple of quotes from President Bush's morning press conference:

"The bill I will sign today will help ensure that we do remain the most competitive and innovative nation in the world. I thank members of Congress from both parties who worked hard to secure its passage. I particularly want to thank Senators Pete Domenici, Jeff Bingaman, Lamar Alexander and John Ensign, as well as Congressmen Bart Gordon and Vern Ehlers".

"You know, this bill shows that we can work together to make sure we're a competitive nation. There's a lot of areas where we can seek common ground coming this fall, and I'm looking forward to working with members of both parties to do that".

Below are the basic bullet items from the white House fact sheet:

The President Appreciates Congress' Bipartisan Response To The Competitiveness Challenge Since He Announced ACI In January 2006. He appreciates House and Senate appropriators' support for funding for ACI basic research programs starting in FY 2007 and commends them thus far in the appropriations process for fully funding his corresponding FY 2008 budget request for the National Science Foundation, the Energy Department's Office of Science, and the Commerce Department's National Institute of Standards and Technology.

As The President Proposed, The Act Supports Doubling Funding For Basic Research Programs In Physical Sciences. This increased funding will encourage scientists to explore promising and critical areas such as nanotechnology, supercomputing, and alternative energy sources.

The Act Authorizes The President's Math Now Proposal To Improve Instruction In Mathematics. The programs will give teachers research-based tools and professional development to improve elementary, and middle school students' achievement in math.

The Act Authorizes The President's Proposed Advanced Placement/International Baccalaureate (AP/IB) Program. This program would expand low-income students' access to AP/IB coursework by training more high school teachers to lead AP/IB courses in math, science, and critical foreign languages in high-need schools.
