I have a short-wave transceiver that operates in a wide range of frequencies, its wave impedance is 50 Ohms. I also have a simple antenna in the form of a…
All wireless chargers contain a signal generator and an emitting coil. I took two wireless chargers for analysis, one deppa and the other unnamed The deppa charger contains an STM8S003…
The SI5351 generator can be controlled using Arduino. To do this, connect the SCL SDA and the generator power to the Arduino board. In the Arduino IDE, search for the…
The Si5351 is an I2 C configurable clock generator that is ideally suited forreplacing crystals, crystal oscillators, VCXOs, phase-locked loops (PLLs), andfanout buffers in cost-sensitive applications.Based on a PLL/VCXO +…
This is an experimental generator based on the IRF510 transistor for short waves. Experimental because the frequency of this generator is unstable. I received the signal of this generator at…
From a long wire and a matching device, you can make a Fuchs antenna for short waves to conduct radio communications over very long distances This antenna works well at…
The 74LV14A provides provides six independent Schmitt Triggerinput inverters with standard push-pull outputs. The device isdesigned for operation with a power supply range of 2.0V to 5.5V.The inputs are tolerant…
A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by overcurrent. Its basic function is to interrupt current flow to protect equipment and to…
Inside the radio control car on the electric motor I saw such an LC filter The filter contains a 100n capacitor in parallel with the motor and two 4 μH…
Using the CD2003GP (TA2003) chip, you can assemble a simple and fairly good-sounding FM radio receiver. In this article I will tell you how to assemble it with electronic tuning…
The CD2003GP/GB is a monolithic IC designed for use as a FM/AMradio system.Combined with audio power amplifier IC, a suitable FM/AM radio can beconstituted. Itsfeatures are:● No need for FM…
A simple single-sideband radio transmitter with which you can carry out radio communications over very long distances. The transmitter is built on the principle of phase shift. A generator is…
If you see an electronic component on the board with the designation 000 or 0, then be sure that this is a regular jumper or a resistor with zero resistance.The…
On my Kugoo m4pro electric scooter, the TF100 on-board computer stopped turning on. This happened after the wires going from the computer to the control unit became short-circuited. I fixed…
In inexpensive radio control models you can find two chips RX2 and TX2. RX means a chip for receiving a signal, and TX for transmitting a signal. Based on these…
A simple and clear experiment on how a Faraday cage works. With the help of a Faraday cage you can jam radio waves or a cell phone signal. For this…
If you have a high voltage source, then you can assemble an ion fan on it. The wind will be created not by the blades, but by the high voltage.I…
This high-frequency generator can carry out interesting experiments, the generator is called a “Tesla coil”. There are low-frequency Tesla coils, this coil is high-frequency. The generator is made on the…
