      How to Read Resistor Color Code

      Resistors can come in different sizes and shapes allowing for different voltages to go through it. However, unless the size of the resistor is large, the code is rarely written on it because it would require very tiny markings. Therefore, a system was developed to use colors to determine the resistor code. In other words,

    • Infrared Sensors

      Infrared Sensors

      An infrared sensor is a device that emits and/or receives infrared waves in the form of heat. While most infrared sensors transmit and receive infrared waves, some can only receive them. These types of infrared sensors are known as Passive Infrared Sensors (PIR sensors) or motion detectors. What is an Infrared Detector? An infrared detector

    • BGA (Ball Grid Array)

      BGA (Ball Grid Array)

      BGA (Ball Grid Array) is one type of packaging for surface-mounted integrated electronic circuits (integrated circuits whose components are actually ‘mounted’ or affixed on the surface of the printed circuit semiconductor board). A BGA package simply looks like a thin wafer of semi-conducting material that has circuit components on only one face. The Ball Grid

    • Piezoelectric Transducer

      Piezoelectric Transducer

      A piezoelectric transducer is a device that converts electricity into mechanical forces or vibrations. Although piezoelectric transducers have other uses, ultrasonic devices require them. Piezoelectric transducers usually converts electricity into vibrations and vibrations into electricity, although this is not always the case. They rely on two phenomena known as “electrostriction” and “the piezoelectric effect.” How

    • What is JFET?

      What is JFET?

      Junction gate Field-Effect Transistor (JFET) is also known as JUGFET. The JFET is the most simple type of field effect transistor currently in use and has either voltage controlled resistance or an electronically controlled switch. When using a JFET, the electric charge flows in a semiconducting channel that is located between the source and drain

    • Ham Radio Software

      Ham Radio Software

      Ham Radio Software, also known as Amateur Radio Software, refers to computer programs designed exclusively for ham radio equipment. Once thought to be a means of communication between radio enthusiasts, ham radio now coexists with software including data and contest loggers, log books, Morse code tutors, and antenna design aids. In the 21st century there

    • TRIAC


      A TRIAC is used in AC power control applications in order to switch high voltages over both parts of the AC waveform. As a result, TRIAC circuits are used in a number of applications that require power switching. The TRIAC was developed after the thyristor, which controls AC current over one half of the cycle.

    • Azimuth


      Azimuth is a measurement at an angle used in the spherical coordinate system. To find a point of interest, the observer creates a vector that is then projected in a perpendicular fashion onto a reference plane. The resulting angle between the projected vector and the reference vector located on the reference plane is the azimuth.

    • MURS (Multi Use Radio Service)

      MURS (Multi Use Radio Service)

      MURS, or the Multi-Use Radio Service, is a public radio service created by the FCC in the Fall of 2000 that can be accessed by any individual for personal or business-related purpose. MURS was created for the general public to use without acquiring a license to broadcast, but requires that users remain within the frequencies

    • GPS Jammer

      GPS Jammer

      GPS stands for Global Positioning System. It is used by individuals, commercial entities and the military for navigational purposes. GPS uses 24 satellites that orbit the earth and send radio signals. The GPS satellites work with a GPS receiver which today can be found in individual handheld units, car navigational systems, boat navigational systems, highly
