Welcome to the repository for my PCB design project focused on creating a reliable voltage regulator circuit capable of delivering both 5V and 9V outputs. This project aims to provide a stable power ...

This circuit is a small +5V power supply, which is useful when experimenting with digital electronics. Small inexpensive wall transformers with variable output voltage are available from any ...

The Arduino Uno already has a 3.3V pin, but it can only provide upto 50 mA. For my purposes (esp8266), I needed to supply a constant 3.3V with current that could go as high as 170 mA. The Uno's 5V pin ...

There are different types of inverters available in market, but their circuits are generally complex, so their cost is high. Here is a proposed low-cost inverter circuit based on MOSFET IRF250, which ...
