Chiming, Scrolling LED Matrix Clock

“Matrix clock with scrolling time, date, day of week, temp, humidity and event notifications. I wanted to build upon the clock logic I developed for the previous clock but put it into a more visible format. This clock is built …

ILC1-1/8L Clock

“Project: ILC1-1/8L Clock This project was undertaken to make use of the ILC1-1/8L VFD tubes, otherwise the project uses standard components and provides the display with time, date, Chimes, pressure, humidity, temperature centigrade, and Fahrenheit. Using …

Vacuum Fluorescent Display Clock

“Despite the fact that it’s been around for a long time, the vacuum fluorescent display (VFD) is still a very attractive type of display. It’s viewable in bright light but is easily dimmable for comfortable viewing in the …

Arduino / ESP8266 RS485 MODBUS Anemometer

“The objective is to find an easy way to implement RS485 on an Arduino Uno, then to adapt it to an ESP8266. The anemometer will be a part of a bench of measures that will be added to the wind …

Aquarium Auto Lighting System

“In this DIY guide I will show you how to make your own Arduino aquarium auto lighting system. In this project I decided to make my own PCB that is based on Arduino UNO microcontroller - Atmega328p. Bellow you will find …

A More Complete Air Quality Monitor

“Samples all 6 metrics the EPA uses to calculate Air Quality Index: 2.5 & 10um particulates, O3, CO, NO2, and SO2, and calculates AQI. This prototype air monitoring system measures all six pollutants the EPA factors into its composite Air …

Arduino LIXIE Clock

“Hey guys! I Hope you already enjoyed my previous instructable “Arduino MIDI Controller DIY” and you are ready for a new one, as usual I made this tutorial to guide you step by step while making this kind of super …
