Arduino Bar graph Stereo VU meter on VFD display GP1287
Pavleski Dec 13,2023
 A VU meter, also known as a Volume Unit meter, is a device used to display the audio signal level in decibels (dB) in real-time. It is commonly found on audio equipment to help users monitor and control audio levels. Some time ago, in one of my previous videos , I presented to you Analog style retro look VU meter on VFD display.  This time, I will also describe a way to make a VU meter on the VFD Display, but this time in the form of a Bar Graph. A bar graph VU (Volume Unit) mete...

InfiRay Xinfrared P2 pro thermal camera detailed Review
Pavleski Dec 12,2023
 A thermal imager, also known as a thermal camera or infrared camera, is a device that captures and visualizes thermal or infrared radiation emitted by objects and surfaces. Today I received the package containing the thermal imager that I ordered some time ago. The model is InfiRay Xinfrared P2Pro + Macro Thermal Camera for Android Smartphones. The package is well packed and protected from damage and arrived here to Macedonia in less than a two weeks. let's see what this sturdy and qu...

LO Guv'nor: Si5351-based 3x clock generators for the workbench
Deegan Dec 10,2023
This is a very simple way to transform the widely used Si5351 modules into a useful lab/workbench tool. The entire purpose is to get access to these three clock generators--which can provide clocks in the low kiloHertz up to hundreds of MegaHertz--with minimal interruption to your workflow.A rotary encoder, an OLED display, and a few momentary switches are all glued together through this basic PCB and bundled with a Nano and the code that provides a quick, and hackable, user interface to the clo...

Advanced Plasma Rife Machine with internal Carrier Oscillator
Pavleski Dec 08,2023
 Rife machines are often promoted as devices that emit electromagnetic frequencies to destroy pathogens, including viruses and bacteria. However, these claims lack robust scientific validation. Royal Raymond Rife, the inventor of the Rife machine, claimed that it could treat various diseases by transmitting specific frequencies.  In several of my previous videos, I described the principle of operation of these devices, as well as practical examples of making simple and advanced Ri...
