If you live in the United States, you’re likely well-familiar with our typical wall-socket setup. Your plug has two flat pieces of metal roughly half of an inch wide, with one side sometimes being slightly wider than the other. Your wall socket has two slots that match this, with one side also being slightly larger than the other. However, sometimes there’s a variance: some plugs have a third prong below and between the normal two, and most electrical sockets also have a third hole to match this plug. What’s the difference between these two types of plugs and is one better than the other?

To put it simply, yes, one is better than the other. When it comes to electrical plugs, the old adage “less is more” does not apply—the three-prong plug is far better than a two-prong. To learn why, let’s discuss the difference between the two.

In order for electricity to flow, you must complete a circuit. A circuit essentially is a connection from your power source to the device, and then from the device back to the power source. The line that brings power from the power source to the device is called your “hot wire”, which is most often red and comes off the positive terminal (noted by the large “+” sign). The line that then returns from the device to the terminal, usually a black wire connected to a “-“ sign, is known as the “neutral wire.” A plug must have both of these lines in order to work.

However, the third prong in a three-prong plug is a “ground” plug, which dramatically improves safety. When an unexpected burst of electricity happens, such a short in the device or a surge from your power supply, the ground plug will take that abundance of additional electricity and move it away from the device and down into the ground where it is safe. This prevents your device from being overloaded which can cause overheating, sparking, and fires in addition to ruining it.

Three-prong plugs didn’t become the standard in homes in North America until the late 1960s. If you have a home that was constructed around this time or after, odds are your wall sockets are probably already of the three-prong variety. Two-prong plugs can work with three-prong sockets just fine, and you’ll rarely experience any issues.

However, if you have any old two-prong plugs, you’ll likely need your electrical system updated in order to upgrade to a three-prong setup. Properly installing ground wires can involve several hours of electrical work and even cutting into your walls in order to do so properly, so it’s a rather large undertaking. However, it’s by far the safest and most prudent option.

Another option that doesn’t involve tearing open your walls is to install a ground fault circuit interrupter outlet, otherwise known as a GFCI. These sockets are two-pronged, but feature a miniature circuit breaker that measures the resistance through a plug and mechanically shuts off when the risk of a shock is present. While this can help you avoid being shocked by a faulty device, there is still no ground wire present so your electronics are not protected from a power surge.

Emergency power systems traditionally use generators powered by gasoline, propane, or diesel fuel.  The purpose of investing in one is to provide your home or business with a way to generate electricity in case a power outage occurs.  This can be invaluable when it comes to maintaining a comfortable temperature during outages, protecting computers and other hardware, preventing food spoilage, and a myriad of other things you take for granted while electricity is readily available to power everything.  Fortunately, even better options have become available that don’t require noisy traditional generators.

Have you heard of something called an Indoor Generator™?  Instead of being powered by messy and pollution causing fuels, these battery-powered units can be set up conveniently inside your home or business.  There are many reasons why these kinds of backup power generators are preferred by so many home and business owners.

With all of these benefits and the obvious versatility of indoor generators, it is clear why many people prefer them over standard generators.  A reputable Dallas or Plano electrician can easily get one set up for you today.

I have a great deal of interest in digital photography, but my life is as crazy as anyone else’s. My son, family, and work keep me busy from dawn to midnight every day. I’ve never had time to cultivate any photography skills, even though I’ve always been very interested, sitting on the edge of my seat, if you will, for a chance to take some digital photos in order to learn a little about how capturing light can create astonishing works of art.

My interview with Matthew Danser had given me my long sought “excuse” to try out some photography techniques. But it also required that I put in an honest effort. The thought in the back of my head: These photos are going to suck. Probably a lot. And they will most likely be seen by the thousands of people who visit this blog monthly. Second gulp.

But I’m the kind of person so riddled with ADHD that even my paranoia about being judged on a mass scale can only last about three minutes before the audacity to try anything resurfaces and action is taken. So here’s what happens when a total amateur who has no idea what he is doing tries to “Paint with Light.”

A one-dollar flashlight from – you guessed it – the Dollar General. One dollar. Even. Gotta love it. Especially since it’s all I could afford, seeing as how I’m still paying off the aforementioned Nikon that I bought to take photos of our baby son. (True, a million pictures have been taken of him during his first year-and-a-half on Earth. However, 999,999 of those photos were taken with an iPhone. Go figya.)

THE PLAN, STAN:

The plan was to wait until it was dark in the apartment and do some light painting. I knew that I could use the Shutter mode on my camera to set it to take exposures of up to thirty seconds. I saw that my camera also had an option for bulb release, so, invoking Danser, who recalls how his girlfriend had to hold down the button on his camera for a full thirteen minutes, I determined that if I asked really nicely, I might be able to persuade my wife to hold down the trigger to get exposures longer than thirty seconds. Otherwise, thirty seconds was my window of time to do all the light painting I could.

I started off pretty timidly. I had seen photos online in which people used long exposures to create squiggly lines. The most popular examples are pictures of traffic at night, headlights and tail lights streaming, giving you a sense of the fluid motion of busy intersections. You’ve also seen those nature pics in which streams and rivers and clouds and stars become gauzy with movement because of long exposures.

But what I really like about Danser’s work is the use of color. The effect of running inside the hut and popping off red-gelled flashes shown at the beginning of this blog post (Matthew Danser! And happy lightpainting, everyone!
