Leach amplifier design is very high quality and has many applications. PCB design is very good in these projects. Source eagle CAD files material list measurement values are given. The author gave detailed explanations about transistor selection, problems encountered, solutions and other issues. I am adding the translation without editing. Amplifier LVA100 I have been…
Output transistors in the 200W Amplifier circuit are TIP2955 and TIP3055. Working voltage is 2X42V DC symmetrical (2X30V AC). Power supply rectifier, filter, fuses, amplifier and low high bass control layer are on a single PCB. TL084 Op amp is used for the low high bass circuit, you can make the selection with the switch…
AVR DIP adapter board designed to use with NGO200, AVR-ISP and other programmers. Atmel DIP40, DIP28, DIP20, DIP14, DIP8 packages are all on the tesk card. Allows you to program ATMEL AVR microcontrollers in a DIP package. ATtiny, ATmega etc. There are 3 different projects for the AVR DIP adapter card. All of them have…
The purpose of the Charger is to overcome some of the limitations of the basic charger and offer users more flexibility. The advanced charger is based on similar hardware to the basic charger. The main differences are in the management of charge/discharge profiles, which can now be entered “locally” and without computer support. Differences from…
This project is about the design and subsequent implementation of independently operating active cooling for LED components. Its basis is a 12V fan used for efficient heat removal. ATMega16 microcontroller was used as the control element. A circuit that effectively and appropriately meets the current cooling needs of the LED module using external sensors, increasing…
Simple Circuit for measuring low resistance values. It is designed to measure low resistance values from 0.01 to 19.99 Ohms. The measurement circuit and the voltmeter must be fed from two separate power sources (battery). You MUST Use Two Separate 9 Volt Batteries in All These Circuits. Using a double-contact switch, you can connect both…
When implementing control systems, you may encounter many problems of an analog-digital nature. One of these is to detect whether alternating current of a certain intensity passes through a particular cable; This could be a signal that the machine is working properly or vice versa. Current Transformer Module relieves the designer from the burden of…
I implemented the “200watt 300watt 400watt 500watt Amplifier Circuit” project that I shared years ago. Actually, I wanted to do it when I shared it, but quiescent current adjustment, measurements etc. I don’t like it 🙂 But after receiving occasional feedback about this amplifier for a long time, I wanted to try it. Since the…
A more stable, stable version of the 100 Watt Mono Amplifier known as ZENER in Colombia. It can deliver 100W power with an 8 Ohm speaker and can also be used with a 4 Ohm speaker. Its noise is very low, and it does not make an explosion sound when opened. Even though I use…
When the DS18B20 Temperature Sensor is transported over long distances, there is a danger of high voltage pulses being transmitted to the cable connecting the sensor to the control unit. If protective measures are not taken, the induced high voltage will lead to degradation of the crystal substrate where the sensor is located. This causes…
