I have never had the privilege of seeing the northern lights in real life, but my sister lives in northern Canada and has told me about them. (She’s a pretty credible source: She even named her daughter Aurora.) After asking her, “What ARE the northern lights,” several times, I now understand the aurora borealis to be a visual effect of the collision of solar wind and magnetospheric charged particles with the thermosphere. Can you see why I had to ask what the northern lights were more than once? The northern lights are most spectacular near the North Pole and during spring and autumn equinoxes. (And, by the way, no. The northern lights are not Santa’s off-season hobby.) But the northern lights, if there are some geomagnetic storms a-brewin’, can be seen closer to home, too, visible occasionally as far south as Chicago or New York.

Anyway, this guy Winiarcyzk is an astronomy enthusiast who lives in Caithness, which is at the tippy top of Scotland. There’s isn’t much light pollution way up there, so it’s a good place for such a sky-minded person to live and enjoy his hobby. Wonderfully, with this time lapse video of the northern lights, we get to enjoy his hobby, too.

Take a look. Have you ever seen anything more lovely occurring in nature? You know, with all this solar wind, magnetospheric particles, thermospheres, and geomagnetic storms, it sure seems like there is a lot more going on in nature than we can readily sense.

Mechatronics, or mechatronic engineering combines mechanical and electrical engineering to design innovative products and systems. These systems must rely on mechanical and electrical components working together in harmony.

The list includes DVD disc drives, anti-lock braking systems, manufacturing, electric motors and clothes dryers, among others. These devices require electronic controls and feedback systems to interact seamlessly with their mechanical design.

Motor control systems operate by using a programmable logic controller or PLC. This system allows advanced programming and algorithms to dictate a motor’s behavior. Therefore, they can be programmed to control multiple motors or VFDs. A robotic arm or a large factory machine is a good example of this.

In addition, PLCs can accept inputs from a wide range of sensors and switches. This allows precise feedback from the machine it controls. Furthermore, it executes built-in software.

The smallest high-precision motors, DC motors, found in computer hard drives and DVD readers. Due to their miniaturization, they can be easily controlled by computer software to perform nearly any imaginable task. A battery powered quad-rotor drone offers us a prime example of DC motor control. Accelerometers and gyroscopes feeding data into a computer controller adjust the speed of each motor independently to keep the drone flying level.

A simple technology that combines electric motors with feedback control, known as servomechanisms, provides valuable information. They utilize a small electric motor, gearboxes, and a potentiometer to produce accurate position feedback to the motor itself. This ensures that the motor has moved to the correct position. Thus, precise movement control of a motor is possible. Applications of servos include RC car steering, fly-by-wire systems in aircraft, robotics, and industrial control valves.

Servos communicate with computer systems, allowing them to be part of larger mechatronic systems, so they can be controlled by PLCs and computer algorithms.

The field of mechatronics constantly evolves. Therefore, as it does, it incorporates cutting edge computer software and mechanical design, bringing to life new inventions. These breakthroughs make modern-day living much easier and more fun.

If you use a standby generator for your home or business, you know how valuable it can be during a big storm or any time when your power supply is uncertain. We tend to get a lot of big summer and winter storms in the DC Metro area, so having a standby generator is crucial for things like keeping food safe and keeping lights on. So if you want to make sure your generator works smoothly when you need it to, it’s important that you keep it well maintained!

After a major storm knocks out power, your generator could be running 24/7 for a few days. To prepare for times like this, here are some ways you can keep your generator in good shape:

In addition to these checks you can do on your own, it’s important to have your standby generator inspected by an authorized sales and service dealer. Remember—many home and commercial generators have a limited warranty and require service from a licensed technician in order to make sure the warranty can be honored.

Standby generator repair and maintenance requirements may vary significantly based on the type of generator you are dealing with. For instance, commercial generators are primarily the alternator type of generators. Alternators have stationary windings (which create the alternating current) and rotating windings (which create direct current). Since rotating windings usually go through a significant amount of friction when working, regular tune ups and electrical repair will see them needing to be replaced every once in a while.
