Introduction I noticed that my LED strip samples have different base thicknesses. Most samples are thin and bend easily; some are thick and hold their shape well after bending. I found only one metal in the strip base. The copper conductors transmit the power along the tape to all the LEDs…

The reflectometer’s capabilities in terms of maximum distance and damage detection accuracy are determined by the sensitivity of the amplifier and some other important parameters. Amplifier sensitivity The sensitivity of the reflectometer, along with the pulse amplitude, is one of its most essential characteristics. It determines the maximum operating range of the…

History and creation reasons The project was created by accident at the moment of urgent need for a mobile standalone device for ISP programming and testing a lot of printed circuit boards with controllers and FPGAs. …

Feature description The INRIKS EX4076KVM is a transmitter and receiver kit that allows HDMI and USB signals to be transmitted over twisted-pair cables for up to 230 feet. Specsheet claims the maximum supported video resolution is 4K at 60 Hz. The transmitter has an HDMI pass-through output port. …

The awesome Colpitts oscillator. Exploring the secrets of the Colpitts generator. Hello, and welcome to our electronic studies! We probably all know that an oscillating circuit consists of a capacitor © and an inductor (L), and its waveform is an ideal sine wave. In the LC resonant circuit, single-frequency oscillations…

The general principle of operation of the reflectometer is elementary: a probing pulse is transmitted from the generator through a directional coupler to the cable; it is then partially (or completely) reflected back from impedance irregularities along the cable length. The reflected impulse arrives at the input of the device…

Are you the type of person who likes listening to good ol’ radio like I do? Unfortunately, medium-wave broadcasting has decayed in the last few decades. There’s nothing in many areas, even at night when medium wavelengths work best. …

We have already covered the topic of connecting a monitor, mouse, and keyboard to a PC (server, laptop, or DVR) at a great distance. The best option is to use an HDMI KVM extender over a twisted-pair cable. With its help, one can complete the simple task of installing a…

My first impression was that I had finally assembled the best overdrive in my entire life. For the first time, a cheap Squier Bullet Mustang electric guitar with stock humbuckers sounded equally good with all the cabinets I usually simulate and switch between when testing a new pedal. Like my…
