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…

Advanced Charger Circuit

| 2024/03/14

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…

Active Cooling System for LED Lighting

| 2024/03/14

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…

Low Resistance Measurement 01-OHM 02-OHM and Others LM317

| 2024/03/14

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…

TL084 LM393 AMS-010 Current Transformer Module

| 2024/03/14

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…

200W 500W Amplifier Powerful Bass Clear Sound

| 2023/10/18

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…

8-OHM 100W RMS Amplifier 2SC5200

| 2023/10/18

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…
