esp32 Midi Prodessor
Fischer Apr 06,2026
It’s an esp32 with 2 independent Midi IN- and 2 independent Midi OUTputs and a USB-host adapter. Incoming MIDI data (notes, CCs, MIDI Clock) can be routed and modulated. Every output can be modulated independently. As of firmware version 0.98 these are the available features per output:Route every input to every outputMerge MIDI data per outputModulate velocity:velocity passthru (no modulation)set to 63set to 100set to 127randomizerandomize around 100 (95..105)Modulate a note’s MIDI channel:pass...

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...

Bare Femto Development Board
Real Space Pro Mar 24,2026
I was thinking to myself....."what if I could have a cheap, tiny microcontroller that was open source?"And That's When it Struck me, The CH32V003 Series!These Boards Need Nothing But A Power Capacitor!So I studied them THOROUGHLY and Came Up with this design!it has 17 GPIO pins!and is only 7mm by 7mm !note: needs a WCH link E for programing through the swio pin

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 ...
