We pick up the fascinating Nixie tubes through displays based on packages of laser-engraved plexiglass plates, illuminated by Neopixel LEDs. For those born in the era of solid-state displays, be they LED, 7-segment, dot-matrix, or even liquid...

In this project we will see how a clock was created that displays the numbers through air bubbles inside tubes. The system consists of an ESP8266 which, through an I / O Expander MC2301, controls the solenoids...

  Lasers have always intrigued me. I have two Helium-Neon Lasers (gas discharge, not solid state), one red the other green. I also have several laser pointers. I like lasers. Several years ago I came across an...

Arduboy is a fully open source portable video game console inspired by the classic Nintendo Game Boy. It is Arduino compatible, which makes it easy for users to modify and program new games. The original Arduboy only...

A dimmer is a device that allows you to modulate the alternating voltage to be given to a load. In this project, an ESP8266-based dimmer was created that can easily control AC loads such as motors and...

In the last year or so, due to Smart Working or Distance Learning, the hours spent in front of the computer have increased enormously. Luckily there is a window behind the monitor for taking those breaks that...

If you design PCB with SMD components, you know how tedious and time-consuming the soldering operation using a classic or air soldering station can be. In industries the reflow ovens are used, that allow the welding with...

  Stopwatches are very useful in several applications and made by yourself using an Arduino, it is really more interesting! This project is really simple, easy to be assembled using few components and has an excellent accuracy...

  Stars appear to stand still, but wait a few minutes and they won’t be in quite the same place. This means that if you want to take a long-exposure image of the sky with your DSLR you’ll have...

  To keep a eye on the current Corona-Virus numbers I created this Programm wich displays the current stats to the Display. More info

  In this project, you’ll build a sensor monitoring system using a TTGO LoRa32 SX1276 OLED board that sends temperature, humidity and pressure readings via LoRa radio to an ESP32 LoRa receiver. The receiver displays the latest...

Ads, notifications, and other messages surround us today, and if you were overwhelmed before, researchers at Ochanomizu University in Tokyo, Japan have figured out how to print text and images in your cup of coffee! This system,...

I²CDriver is an easy-to-use, open-source tool for controlling I²C devices. It works with Windows, Mac, and Linux and has a built-in color screen that shows a live “dashboard” of all the I²C activity. The 61 x 49mm...

  Created for the most famous social network, it displays in real-time the number of likes received by the related Facebook profile, through a giant 5-digit display. Since social networks were born, and Facebook in the first...

Raspberry Pi enthusiasts searching for a small screen suitable for their next pilot project may be interested in the Pimoroni Inky pHAT, specifically designed for the Raspberry Pi 3, 2, B+, A+, Zero, and Zero W or any pi...

POV Displays move through the air at a high enough speed to trick your eyes into thinking that a sequence of flashing lights is actually a solid image. Though interesting enough in two dimensions, LED Instructable maker “Gelstronic”...

  Let’s substitute our 3D printer’s command panel with a dot-matrix that enables the display of graphics, function icons and animations.   We would like to remind you that our 3Drag printer (that prints plastic items of...

We add to Raspberry Pi a TFT touch screen to display the system console, movies and favorite photos or control a relay board … at your fingertips, literally! To avoid using an HDMI monitor the cost well above...
