Here is another great energy saving article from my good friend James Gallett.  I hope you enjoy it and please feel free to post any comments or questions.   Do you know which direction your ceiling fan should turn in order for it to do its job and be economically efficient? Just the other day I had a friend of mine ask me this question, she was wanting to know for her house about the direction of her ceiling fan. I thought I knew the answer, but did some research to Read More...

Brad had all the parts necessary for fixing our unit quickly. I would highly recommend his services. The charges were very reasonable. Thank you for Read More...

Phones are now smart apparently. This has come as quite a shock and one that I’m still trying to reconcile with my expectations. The first mobile phone patent was issued 102 years ago. To reach the dizzying heights of smartness in that time is quite good going. I can only assume that over the next century the intelligence of phones will evolve to a level where they will dispense with the need for humans and start communicating together directly (about what I shudder to think). Or maybe marketing departments should be a little more circumspect in their choice of terminology. (more…)

Every industry or industry sub-sector has its movers and shakers, its pioneers and thought leaders. These people have likely helped shape and evolve that industry to what it is today and what it may become in the future. For this series of ‘An Interview With…’ blog posts I will be posing the same set of questions to leading lights in the electronics cooling community to get their views on various thermal topics. Actually the last question is who to address the questions to next, in that way I hope a self sustaining chain can be set-up (here’s hoping it lasts more than one link!). (more…)

The A/C Handyman was on time to complete the service. When I had questions, he was helpful to answer! Would recommend to anyone. Read More...

The electrical transient testing method has become popular as a useful thermal analysis tool because of its accuracy, high repeatability and rich information content compared to the use of traditional steady state thermal characterization techniques. This paper presents a thermal study of a 16-chip memory module using transient testing. The two variables in this study are the thermal boundary conditions of and the power distribution within the module. By applying the method of network Read More...

Water heater replacement is something that Sinclair Heating Cooling and Plumbing specializes in!  If you have a water heater in your home or place of business you know that it is a matter of time until you will need to replace it.  If you have a tank water heater, I wanted to give some tips on what to look for but also what to expect if you have Sinclair plumbers change-out your water heater. If your water heater tank is in a closet inside your home, business, or garage always Read More...

In a recent survey, 60% of mechanical engineers in electronics companies stated that thermal issues had forced board layout changes during the previous 12 months. While I can’t purport to know how much respins cost within every organization, I’m willing to bet it is not an insignificant amount – especially if the company has a large portfolio. But I know that thermal simulation can help minimize the risk of late stage PCB respins. Copper distribution on a 6 layer PCB. Image courtesy of Read More...

The rate of technological advancement over the last 150 years has changed society beyond measure. Riding the crest of this wave has evolved us to speculate beyond the present, to accept that things will continue to change and to ready us for the acceptance of what the future will herald. However that was then. As the electronic future washes over us in an ever growing number of electronic devices and capabilities there now seems to be a growing sense of impatience with the rate of change. I was led to believe we’d have flying cars by now. (more…)

One of the toughest parts of the process of replacing your central air conditioning is deciding which licensed contractor to hire.  There are hundreds of companies that say they service and install HVAC equipment.  This includes individuals who work out of their garage and have just started installing due to the economy. A couple  of the easiest ways to search for contractors who install a/c equipment is too look in the yellow pages or do a search online.  You will see a bunch of HVAC Read More...

If you’re involved in CFD in education in any way this will be of interest to you. Since shortly after Flomerics were acquired by Mentor Graphics we’ve been working towards getting out products into Mentor’s Higher Education Program (HEP), and we’ve finally got it done.

To my knowledge, the availability of potentially millions of dollars worth of commercial CFD software, plus support and training, for around US$500 annually is unique in the CFD business, so this is something of a game changer. Here are the details:

The planet seems to be consumed by disasters these days, natural and man-made. From massive oil spills in the Gulf of Mexico to earthquakes to erupting volcanoes. Yet there's another potential disaster looming in either the frozen food section of your local mega-mart, or even the residential model r Read More...

I do IT consulting on my own so I thought that there must be smaller companies with hard working honest guys around that do AC work. Google brought up Read More...

Our AC went out completely and I called Bradley’s shop. He told me it would be about 2 hours until he could make it out here to Gold Canyon. He busted Read More...

The etymology of the phrase ‘red hot’ dates back to the 14th century describing the colour attained by metal as it is heated. When attributed to people it can euphemistically be used to describe passion and attractiveness. Any colourful picture output from a numerical thermal simulation of an electronics system will have red depicting hot and commonly blue to show cold. There are other colour map options though..

For the fifth time in less than a year, ACCA has been invited to testify before Congress. On July 14, contractor Robert Ring will testify on behalf of ACCA before the U.S. House Small Business Committee. He will testify on bonus depreciation and the impact of tax incentives on small business owners. A copy of his written testimony can be downloaded here. As soon as possible after the hearing, we will update this post with links to video footage. UPDATE: Videos from the hearing, including Read More...
