You drive a car, you are in traffic every day, it is important to record every incident that happens, the best way to do this is to have a dashcam. That's why today I present Viofo WM1 small compact with very good components that will provide excellent quality. The device is small in size, so it is easy to hide it so it doesn't get in the way while driving.  The camera is without a screen, which allows the capacitor to last longer in parking mode, and also allows it to be so compact. All settings and control of the camera is done through the application, which is very simple and enables all simple adjustments.  When it comes to the camera sensor, it is a Sony sensor that provides excellent performance during day and night driving, and there is also a Novatek NTK96565 processing sensor. Recording takes place in 2K resolution with various bit rate options. This recording takes place at 30FPS, which is decent and it is possible to recognize all the details while driving. Also, th...

Antenna for radio (WOUXUN)

Autor -

Radio engineering, an antenna is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver. In transmission, a radio transmitter supplies an electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves). In reception, an antenna intercepts some of the power of a radio wave in order to produce an electric current at its terminals, that is applied to a receiver to be amplified. Antennas are essential components of all radio equipment.
An antenna is an array of conductors (elements), electrically connected to the receiver or transmitter. Antennas can be designed to transmit and receive radio waves in all horizontal directions equally (omnidirectional antennas), or preferentially in a particular direction (directional or high-gain antennas). An antenna may include components not connected to the transmitter, parabolic reflectors, horns, or parasitic elements, which serve to direct the radio waves into a beam or other desired radiation pattern.
Antennas are required by any radio receiver or transmitter to couple its electrical connection to the electromagnetic field. Radio waves are electromagnetic waves which carry signals through the air (or through space) at the speed of light with almost no transmission loss.
Antennas can be classified as omnidirectional, radiating energy approximately equally in all directions, or directional, where energy radiates more along one direction than others. (Antennas are reciprocal, so the same effect occurs for reception of radio waves.) A completely uniform omnidirectional antenna is not physically possible. Some antenna types have a uniform radiation pattern in the horizontal plane, but send little energy upward or downward. A "directional" antenna usually is intended to maximize its coupling to the electromagnetic field in the direction of the other station

Homatics Box R Lite 4K Is it better than the others?

 Welcome to a new written review of a very interesting competing AndroidTV box. It is about the device Homatics Box R Lite 4K, which has a very nice design and very good specifications for the price of the device itself.  I've been using this device for more than a couple of weeks and I didn't worry that it crashed, that some application stopped working, The Coretex A35 processor is so well matched with the 2GB memory, which is enough to work.  The storage proctor is 8GB, but a decent 4GB remains available, which is quite enough for applications that are used on a daily basis. Only support for 4K resolution that supports HDR. The entire set is completed by the open video format AV1 and Dolby Audio, which complete the entire package. The device itself is small in size, and this design does not affect the performance, the device does not overheat. The design is so beautiful and minimal that it fits into any environment. Well, if it bothers you, you can hide it because the d...

  You are going on a trip with someone, you are separated in  different vehicles. I have a solution to your communication problems that will be completely free. These are devices from Retevis, model RT49P / RT649P. These are small devices that do not require a license to use. You will also be surprised when you read what this device model has to offer. The device operates on the UHF spectrum and also has the ability to listen to NOAA weather satellites.  On the device itself, you have 22 channels on which the frequencies for use are stored. The power of this device sounds small but it is actually enough for what it is intended for. And the power is for LOW 0.5W and for HIGH 2W. The power of this device is via 3 NiMH rechargeable batteries. The device itself can be charged via a USB cable.  This device is very easy to use, and this is contributed by the small LCD screen with all the necessary information. And below that screen are buttons to control the enti...

            Today we will talk about a device that is intended for beginners in this sport and which will be  used for some small things, which can be made much easier by this small device. It is a Retevis RT85 device for communication via radio waves. This device operates on VHF and  UHF  frequencies.  We will take a short break around the device and do a little education about the frequencies on this device. So to start with VHF the frequency range is from 136,000 to 174,000MHz . This spectrum is intended for open space where there are not many obstacles like buildings and the like. This spectrum is 2m long when viewed in the coordinate system. And while the UHF spectrum ranges from 400,000 to 470,000MHz . And this spectrum is intended for an urban area where there are a lot of obstacles and buildings. This device covers both spectra and is intended for all situations.  For very little money, get a device...
