Most people are familiar with smoke alarms or detectors as they are requirements in all commercial and residential buildings. But how do they work? And how do you ensure that they are functioning at their top performance?  If properly maintained, smoke alarms can and have been proven to save millions of lives in the case of a fire.

In general, there are two different types of smoke alarms.

Ionization means that the device is equipped with two plates that create a charge. When smoke passes between these plates, the charge is interrupted and forces the alarm to sound. In contrast, a photoelectric smoke detection system works similarly but is equipped with a light beam. When smoke passes in front of the light, the alarm sounds. Each function is beneficial in different instances and because of this, one is not necessarily better than the other. It is, however, recommended to have one of each of these functions on each floor of your home and in high-risk areas such as the kitchen or near fireplaces or heating appliances.

To ensure your family’s safety, it is recommended to check your smoke alarm once a month. In order to do so, you can simply push the test button on the smoke alarm. If it does not sound the alarm, you should check the battery and replace it immediately. You could also light a match near the smoke alarm to ensure that it is functioning at top performance.

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!

The secret of creating a great home entertainment system is designing a layout that fits into your home while keeping hidden as much of the understructure (i.e. the wiring) as possible. To achieve this, some homeowners hire professional electricians to send wires through the walls and ceiling. But people often take on the work as a do-it-yourself hobby. Although this is a much better DIY project than, say, attempting to install a furnace or an air conditioning system on your own (you should never try either), it can sometimes lead to wiring issues that are difficult to diagnose and fix. When problems crop up, it’s best to call in an electrician with knowledge of home entertainment systems to assist you.
