What is the purpose of this type of device? There are cases when it is necessary to multiply the signal from one video source (TV-tuner, PC, video recorder) to several displays.

What makes up a cable locator receiver? Which sensors are used in receivers? What is the purpose of the different types of sensors and various combinations of sensors used? How does one correctly orient the receiver to the cable being traced?

How quickly does the illumination reduce when the supply voltage decreases? How does the illumination decrease due to voltage loss in a long LED strip?

Are you planning to hide this device on a table behind an NVR, TV, monitor, etc.? Or will the transmitter and receiver be placed in plain sight, e.g. on a wall, under a tabletop, or on a surface in some other way?

How does a generator's signal frequency affect the range of the cable location signal? What cable identification frequency is more efficiently? Why can cable identification at low frequency be more reliable? And when is passive location used?

What happens if the installer chooses the wrong connector for the LED strip or lights? What happens when a connector passes a high current? What is more dangerous - a thin wire or a low-quality connector?

There aren't many consumers who pay much attention to design when choosing an HDMI extender over a twisted pair network cable. But it can be quite important in some cases. What if you choose a compact type of extender?

This post contains a brief introduction to cable location principles. What does a typical locator consist of? Active/passive location methods. Cable connection methods.

How does the power consumption affect the LED chip heating? Can I mount the LED strip on the chipboard directly without the aluminum profile? Is COB technology really more efficient at dissipating heat from LED chips than traditional SMD technology?

Buyers of HDMI extenders often ignore an additional feature: the HDMI pass-through output of the transmitter. I will look at what it is, where it can be useful, and whether it is worth overpaying for it.

Active and passive modes of cable routing. Three ways of active tracing of power and telecommunication cables.

Experiment/study LED strip internal conductors resistance. Voltage reduction in long strips. Influence of LED strips inner conductors resistance on the segments power supply. How to connect long LED strips correctly?

The Lenkeng LKV372AE-4.0 is a simple twisted-pair HDMI extender that has the additional function of sending the IR signal back. This means that i send an HDMI signal from the transmitter to the receiver and i can send an IR signal back.

I had another twisted-pair HDMI extender up to 230 feet for testing - Lenkeng LKV375N. This is an inexpensive extender that works on HDBaseT technology.

The Lenkeng LKV372AE extender is considered basic in Lenkeng's lineup. It transmits video with a maximum resolution of 1080p at 60 Hz for a distance of up to 230 feet over a CAT6 cable.

How does air dissipate heat from the LED strip? How much air cools the LED strip?

Full simulation of led lights under the cabinet How hot are the LED strips on the aluminum profile? How hot are the LED strips on an aluminum profile in the chipboard?

Heating of different types of led strips on chipboard. How hot are the LED strips on chipboard without an aluminum profile? How hot are these LED strips on chipboard with an additional diffuser?

Let’s look inside a COB LED strip (and what is it anyway?) Introduction about the construction of a white light LED strip. Removing the phosphor and examining the chip sizes.

Real power consumption of led strips and heating without heat sink. How much does the real power consumption of LED strips differ from the power consumption declared by the manufacturers? How hot do LED strips of different types, wattages and widths under different conditions?
