Build a Long-Range Wireless Appliance Control System
Jain Apr 03,2026
Controlling electrical devices over long distances is often challenging, especially when internet connectivity is unreliable or unavailable. This project demonstrates a practical solution using LoRa communication, enabling you to operate appliances like lights and fans from a smartphone—even across large distances—without relying on Wi-Fi or complex networking.By combining LoRa with Bluetooth Low Energy (BLE) and a microcontroller such as Arduino Nano, this system creates a bridge between short-...

Programmable RGB Thermometer
Adhikari Mar 31,2026
Summer has been relentless this year. My passion for Bitcoin mining took a major hit due to the immense heat from my miners and the electricity costs required to keep them cool and running. There were times when the miners overheated so badly that I had to shut them down "manually" to prevent a fire hazard.To automate the shutdown and restart process and to enable remote temperature monitoring, I built an RGB thermometer with its own web interface that can control home appliances based on temper...

Pinball RPU V102 project
Zorbas Mar 22,2026
Retro Pin Upgrade (RPU) is an inexpensive circuit board (DIY for under $50) that plugs into a pinball machine’s main board (MPU) and takes control. Using an Arduino microcontroller, RPU takes over the lamps, solenoids, switches, displays, and sounds of a pinball machine in order to reprogram it with all new rules. RPU can also talk to newer peripherals (like displays, RGB lamps, and polyphonic sound boards like the WAV trigger) so new features can be added to pinball machines.More info can be fo...

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 construct 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 ar...
