This voltage converter is designed to generate 220 volt mains voltage from 12 volts DC, although it also works perfectly well with a reduced voltage source down to 8 volts. Power can be increased to 100 watts using an IRF3205 reverse conductivity field effect transistor. A car battery serves as the power source. The converter …
Georadar “Radalit”. General description, block diagrams, terminology Block diagram of the georadar “Radalit” Figure 1 shows a block diagram of the georadar (GR) “Radalit”. Fig.1. Block diagram of the georadar “Radalit” Functionally, the GR consists of five modules. The power supply and battery modules, VT1 and V3, provide power to the GR and charge the battery. The …

Go to v 2.0.0 Discription Arduino Multimeter is a project based on an Arduino microcontroller and a smartphone. It is easy to do and does not require many …
Old-style hard drives (not SSDs) use very good brushless BLDC motors. And it often happens that the propeller itself has burned out, but the engine works fine and it is a pity to throw it out. Brushless motors are more durable than conventional brushed motors because they do not have a commutator – brush commutator. …
Using the device, you can remotely android control RGB LED strip (or RGB LEDs) via any Android device with an integrated Bluetooth module. A distinctive feature of this project is the simplicity of the hardware and software part of the system, which includes a Bluetooth controller, a portable Android device with an installed application (smartphone, …
This is probably the simplest frequency meter built on the ATtiny2313 microcontroller . It allows you to measure frequencies up to 10 MHz in four automatically switched ranges. The smallest range has a resolution of 1 Hz. Frequency counter specifications Band 1: 9.999 kHz, resolution 1 Hz. Band 2: 99.99 kHz, resolution up to 10 Hz. Band 3: 999.9 kHz, resolution up …
In the world of radio amateurs, especially during repairs and building a new devices, you should have a device for measuring of capacitance and inductance, this device is called LC meter. Today, on the Internet, you can find many schemes of such devices, complex and very expansive. But you can create your own LC …
Capacitors work without problems, but sometimes they encounter power failures or malfunctions. If the problem is noise, then there is a simple solution, just add more capacitors. But if that doesn’t work out, what went wrong? The root of the problem is that we take capacitors for granted as ideal devices, but they are not. These unexpected results are due …
LM2596 regulated power supply Considering that the efficiency of the LM317 regulator is low and the heat generation is important, it is intended to make a new adjustable regulated power supply . When you search on the website, You will find many adjustable voltage regulators use LM2596 IC. Switching power supply, high conversion efficiency (more than 85%), …
DIY simple obstacle avoiding car This simple obstacle avoiding car uses ultrasonic waves for distance measurement and determines the direction of the car according to the measured distance. Simplified handling of obstacles avoiding, as long as there are obstacles, turn right. To save costs, only one ultrasonic wave module, so only objects in front of …
