Holi Circuit
Jiwarajka Mar 15,2026
The Holi Circuit represents a clever fusion of traditional festive play and modern mechatronics, transforming a manual water balloon drop into an automated, sensor-driven prank. By utilizing the ESP32 as the central processing unit, the system gains a significant advantage in terms of speed and multitasking. Unlike simpler microcontrollers, the ESP32 can manage the high-frequency pulsing required for ultrasonic distance sensing while simultaneously maintaining a stable PWM (Pulse Width Modulatio...

AQI Detector
Jiwarajka Mar 15,2026
The integration of the Raspberry Pi RP2040 with the GP2Y1010AU0F optical dust sensor on a custom PCB creates a sophisticated edge-computing platform for environmental monitoring that bridges the gap between raw analog sensing and intelligent data interpretation. At the core of this system, the RP2040 utilizes its dual-core ARM Cortex-M0+ architecture to provide a level of computational fluidity rarely seen in simple air quality monitors. While one core can be dedicated to the nanosecond-precise ...

Counter-Strike 2 C4 replica
Makes Mar 15,2026
I designed this replica with the goal of making the best real-life representation that anyone has ever shared online. I worked meticulously on this project to make sure as many details as feasibly possible reflected the in-game asset. The final result is an interactive display piece that Counter-Strike fans can build to showcase their love for the game!This website allows you to easily place an order with PCBWay for the circuit board so you can build this project yourself!The design files are av...

USBpwrME..
Elektronikdesign Mar 13,2026
Many times i use USB to power my homebuilt projects and every time i have annoying issues on how to power the DUT in a prectical way during test and develppment. I want to use my bench power supply as power source to have controll of the power into my board so mostly i ended up cutting a USB wire to connect to the power supply.So finally i designed this adaptor to make the connections really easy and universal with some rally important safety features such OVP and polarity protection.Project fil...

PWM MOSFET Driver Board for DC Loads and Arduino/Microcontroller Control PCB
Mar 13,2026
In short, this project makes a very common breadboard circuit into a reusable development tool: compact, easy to understand, easy to assemble, and useful in many small electronics projects.This project is a compact PWM MOSFET driver board for switching low-voltage DC loads from Arduino and other 3.3V/5V microcontrollers. It is designed as a simple, reusable helper board for electronics prototyping, testing, and workshop use. Instead of repeatedly wiring the same MOSFET, resistors, diode, LEDs, a...

Wolf Microcontroller
Jiwarajka Mar 12,2026
The Wolf Microcontroller represents a significant leap forward for the modern DIY electronics enthusiast, merging the high-performance capabilities of the RPI (Raspberry Pi) ecosystem with a rugged, user-friendly design. At its core lies the RP2040, a powerful dual-core Arm Cortex-M0+ processor capable of running at 133MHz. This architecture is a "wolf in sheep's clothing," providing far more computational power than a traditional Arduino while maintaining a small, embeddable footprint. With 264...

Ultimate 2-Player Reaction Timer with WS2812B LED Strips & Arduino
Pavleski Mar 12,2026
 Arcade reaction game is a genre of play designed to test a player's physical response time and hand-eye coordination against increasingly difficult visual or auditory cues. These games are usually dead simple (a single button, a joystick, or a touch screen), and anyone can play immediately, but mastering the timing is the real challenge. This time I will present you with a way to make such a game using an Arduino microcontroller and a WS2812B type LED Strip. This game is designed for ...
