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.

Environment monitoring system
Jan 19,2025
Environment Monitoring System with Arduino Nano, DHT11, BMP280, and LCDWhat’s the Project About?The Environment Monitoring System measures and displays real-time environmental parameters such as temperature, humidity, and barometric pressure using an Arduino Nano, DHT11 sensor (for temp & humidity), and BMP280 sensor (for pressure and temp). The data is shown on a 16x2 LCD, making it a simple, cost-effective solution for weather stations, indoor climate monitoring, and more.Why Did I Decide ...

An alternative clock (Floppy Voltmeter Clock)
Floppy Lab Jan 18,2025
What is it?The Floppy Voltmeter Clock is a special clock that instead of using the usual rotating hands, or seven-segment displays in the case of digital clocks, uses two analogue voltmeters in a retro style. It is therefore a unique and very special object. It is designed to be open source and easily made, so anyone can create one and put it in their desk, workshop or living room.The ideaWandering around on YouTube I have seen that lately many people are building systems to display the time, so...

OLEDDuino-1.3 - OLED-oriented Devboard
Aliyev Jan 17,2025
This project is aimed at beginners and professional DIY makers.The design feature is that the OLED is mounted on top of the board and fixed with nylon stands.The bezel printed on a 3D printer gives the device a finished look.Considering the design, it is very easy to create projects using an OLED screen: be it a voltmeter, thermostat or something else.(The work is underway on GitHub, where the sketches will be located)The board is based on the Arduino pro mini circuit with minor changes (see dia...

Arduino and esp car clustering !
Jedrj Jan 17,2025
I embarked on a project connecting an Arduino Uno with an ESP module (such as the ESP8266 or ESP32) to a car’s dashboard for several personal reasons, combining my passion for electronics, programming, and automotive technology. Below, I explain why I started this project and how it works from my perspective.Why I Started This ProjectPassion for Electronics and Programming: I have always been fascinated by microcontrollers and the possibilities they offer. Working with an Arduino presented an op...

Arduino VFO Project with a Large LCD Display
Pavleski Jan 16,2025
 A Variable Frequency Oscillator (VFO) is an electronic oscillator whose output frequency can be adjusted or varied over a specified range. It generates periodic waveforms, whose frequency can be dynamically controlled. VFOs are crucial in a wide range of applications, particularly in communications, testing, and signal processing. In one of my previous videos I presented a way to make such a device with an ESP32 microcontroller on a color TFT display. This time I will present you a V...
