ESP8266 Nodemcu 4 Ch Relay Module For IoT Project
DAS Jan 29,2025
OverviewThis project allows you to control four relays using an ESP8266 (NodeMCU) via the Arduino IoT Cloud. You can toggle relays using physical switches or control them remotely from anywhere using a cloud-based dashboard. Key Features: Manual Control – Use physical switches to toggle relays. Remote Control – Control the relays from the Arduino IoT Cloud Dashboard. WiFi Connectivity – Get real-time feedback on the relay status. Synchronization – Changes from manual and cloud control stay updat...

ATTiny1614 and VCNL4200 LED Controller
M Jan 27,2025
This project centers on creating a smart lighting system that dynamically turn ON and OFF an addressable WS2812B LED strip based on ambient light intensity and proximity sensing. The system uses an ATtiny1614 microcontroller as the core, interfacing with a VCNL4200 sensor to monitor environmental conditions.The VCNL4200 combines ambient light and proximity sensing in a compact module, providing real-time data. The ambient light sensor (ALS) measures the surrounding brightness, while the proximit...

miniEsp - ESP8266
Tora Jan 25,2025
miniEsp is a practical and powerful upgrade to the ESP-01, offering more I/O options and better voltage protection, all while maintaining compatibility with the existing ESP-01 pin header format.OverviewThe miniEsp is my solution to the limitations of the ESP-01 module. One of the biggest issues I faced with the ESP-01 was its lack of I/O pins, having only 2 I/O pins made it too restrictive for many of my projects. I wanted a more capable, versatile version of the ESP-01, so I des...

DIY ESP32 Bioresonance Rife Machine with ZAPPER function
Pavleski Jan 24,2025
Rife machine therapy is an alternative treatment developed by Dr. Royal Raymond Rife in the 1930s. He believed that certain frequencies could target and eliminate pathogens like bacteria, viruses, and even cancer cells. The machine purportedly generates frequencies that match those of the targeted organisms, thereby disrupting and "destroying" them without harming the surrounding tissue. However, the scientific and medical communities largely reject Rife therapy due to the lack of solid, pe...

Electromechanical Seven Segment Display
Jan 24,2025
Introducing Flippy! The all-in-one modular 3D printed electromechanical seven-segment display. Through the use of 14 electromagnets, each digit is able to quickly and mechanically display both numbers and letters. This creates a unique and satisfying display.This is the main controller PCB as some people had issues with uploading silk screens so I opted to upload this PCB for them. The digit PCBs still need to be ordered separately and the files can be found on GitHub.To build your own, check th...

Measuring wheel PCB
Jan 22,2025
This DIY measuring wheel measures distance as you roll it along the ground (the wheel will have a circumference of 1m). The picture included illustrates the wiring of the electronic display. When a button is pressed, the display counts up. A PCB is needed to clean up the wiring and make it more compact. I decided to make this project to solve the problem of accurately measuring distance when doing some sprinting workouts. Instead of measuring the 30 or 40m required with a measuring tape, I decid...

16 Ch ADC 16 Bit on One I2C Bus
Reboot Jan 22,2025
Four ADS1115 16 bit 4 channel ADCs are on this PCB, sharing one I2C bus to give up to 16 single ended channels.The ADS1115 can operate from 2v to 5.5vThe I2C bus voltage must match the ADC supply voltage or else level shifting is needed for the bus.The analog input voltage must be between 0V and the supply voltage being used.
