Science fiction aficionados may appreciate today’s blog post on one of the fundamental ingredients needed to create an other-worldly retreat where you can … well, space-out. From childhood bedrooms to multi-million dollar estates, science fiction has been the motivation for some of the most amazing spaces ever. Call it your Star Wars Sanctuary, Asimov Alcove, or Halo Haven, sci-fi rooms all have similar characteristics that give it their “universal” appeal. LIGHT.

One of the most popular settings for a fictional future is in outer-space. A black landscape, interrupted only by the flickering of shining planets & stars is the perfect backdrop for sci-fi design. LED fiber optic ceiling lights will make you look like you’re in space.

Patience and attention to detail will go a long way when installing these kits. You’ll find detailed instructions Make a home-made star constellation projector with star printables and a flashlight to mark real constellations!

Did you know that today is National Science Fiction Day, as well as Isaac Asimov’s birthday? 

The controller keeps on monitoring the application requirement in a continuous control loop. It then commands the inverter to produce the required voltage and frequency to meet the application requirements. To do this, the controller, comprised of a microprocessor, takes the input signal from the sensor and compares this with a reference signal. It then generates the appropriate control signal for the inverter to vary its output power.

In a typical application, the controller will monitor process parameters such as pressure, flow rate, temperature or liquid level. For example, an oxygen sensor in a boiler provides a signal to adjust the speed of the fan and control the amount of oxygen in the boiler system.

Today’s drives, using microprocessors, semiconductor power switches, and SMDs are now smaller, compact, cheaper, more reliable and efficient. A typical drive will also include a filter to suppress harmonics generated when converting the DC to AC voltage.
