Video of the SMPS transformer winding shared “before” and “Handmade Toroidal transformer winding machine” to the writings of a Toroid Core Winding machine, additional more wanted to share the video with manual fine-wire or not a machine ideal for multi-turn windings, but a lot of work, especially if it will work in practice, but a…
Before “Advanced SMPS Transformer design program” ExcellentIT and “Ir2153 SG3525 Frequency Calculation Programs for Switch mode power supplies with raisers” shared a very useful programs. Programs prepared by Russian-born Vladimir Denisenko sharing a person known as a Russian electronic forum Starichok51. Starichok51 share of 18 program until it was presented as a very popular used…
Hi guys, I used the new project again with proven performance, sound, price TDA7294 an amplifier IC. This project, in addition to double check before I share tons of “delayed and Led Excitation Speaker DC protection circuit TDA7294 Stereo” and “2X100” projects, we can say that a combination of amplifier circuit (when the minor detail…
Bga removal and soldering of smd integrated cold soldering automatic soldering BGA chip failures again, BGA, flux, gave detailed information about the use of the hot air gun to solder balls was very common back then, and it was expensive and we were again though his legs now the BGA solder paste with a BGA…
On the market there are no potentiometers of 6 channel (I don’t know what the situation is) this potanslar is also used, especially if more than one channel audio 5.1 sound systems needed to make the control of the author, 6 3 piece stereo 2 channel combining potentiometer knobs located within 6 channel made ports…
Made with PIC16F873 microcontroller calculator project .. keypad buttons are used for standard HD44780 LCD assembly prepared with the software. Asm. Hex code there. Addition, subtraction, multiplication, division, decimal and hexadecimal number systems, computing the square root, the inverse value of arithmetic operations can be done and why. source: elektro-shemi.ru alternative link: FILE DOWNLOAD LINK…
It is a circuit for the circuit only show animation, colored lights and sound in proportion to the severity of a circuit to change the animation speed, also have created this. Usually known as disco effects, disco lights, etc.. Mounted to the surface in the form of a circle of colorful glass circuit stepper motor…
I have added to my list of useful, a lot of my work is a system to facilitate the “Preheating Machine” author told that more quickly by pressing the PCB the PCB with the ironing pressure using make, but can be used in so many different things depending on the situation, for example, repair work,…
Gas detector circuit ATMEGA48 microcontroller based on the used gas sensor MQ-4 gas when it detects buzzer with audible warning in addition to the RGB LEDs with a warning status reported in the blinking green, green, flashing red, red. PCB Design SMD components used half the size of a small Leak Gas Detector circuit Resources…
Linear optocoupler IL300 One of the diode is part of the output circuit, the other is used as feedback. IL300 optocoupler is suitable for both direct and transfer AC signal with a bandwidth of 200 kHz via a linearity of up to 0.01%. The function is stable in terms of temperature, while the temperature coefficient…
