The electronic projects involve designing and building a functional device using electrical components like resistors, capacitors, transistors, microcontrollers, and sensors. These projects help learners and hobbyists develop practical skills in circuit design, programming, and problem-solving while exploring various applications in areas such as automation, communication, and IoT (Internet of Things).
AVR High Voltage Programming (Fuses Rescue) While working on a new prototype for my GPS module for Yaesu VX-8DR/DE transceivers, I made some newbie errors burning incorrect fuses into ATmega328P microcontrollers and bricked them. After some research I found MightyOhm’s High Voltage Programmer which could bring them back to life. His programmer was designed as …
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 …

Digital USB oscilloscope Nowadays, the use of various measuring devices built on the basis of interaction with a personal computer is quite numerous. A significant advantage of their use is the ability to save the obtained values of a fairly large volume in the device’s memory, with their subsequent analysis. The digital USB oscilloscope …
GMR Board Introduction The full name of GMR board is General Robot Expansion Board, which is an integrated circuit board designed specifically for the Home Robot Platform (HCR). GMR Board Introduction Three microprocessors (single-chip computers) need to be inserted into this integrated board: two Arduino Nanos and one Arduino Mega ADK. The three processors have been connected …
DIY Air Quality Monitor – PM2.5, CO2, VOC, Ozone, Temperature and Humidity Arduino Meter Have you ever wondered about the quality of the air you breathe, or why you wake up tired after a full night’s sleep or sometimes feel sleepy at the office? Not only can bad air quality have negative health effects, it …
In this tutorial, you will create a real-time audio spectrogram visualizer using a Raspberry Pi development board with an external digital microphone and a TFT LCD display. With it, you can visualize the real-time sounds of your surroundings! The following is a preview of the tool when it is running. The Adafruit PDM MENS expansion …
Introduction Hello everyone! You must know that an 200kHz Digital Oscilloscope is a must-have for every electronics student or hobbyist. To save costs, I suggest using a mobile device such as a mobile phone as an oscilloscope. Since the signal cannot be transmitted directly to the mobile phone, we use the Raspberry Pi Pico to …
MAKER: Dustin Watts Previously, we introduced ” DIY a small square screen to display Raspberry Pi information “. By deploying a piece of Python code on the computer that needs to be monitored, the monitoring data of the machine can be displayed on another small screen through the MQTT network protocol. The project to be introduced in this …
