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 lights. It has the power to handle more than 1200 Watts and it is a project that can…
Roni Bandini is a writer born in the seventies, obviously he likes paper books but after many years of using a Kindle he has become accustomed to some features that he doesn’t want to lose. What features? The remaining reading time for example. Can this feature be implemented for paper books? The first thought was…
In this project we will explain how to make a POV clock in an easy way. POV stands for persistence of vision. It is a kind of optical illusion in which a visual image seems to persist even when the rays of light cease to enter our eyes because they are interrupted for very short…
If you need to strip a cable or two, that’s easy enough. However, if you have to strip and cut several dozen cables all to the same length it becomes a boring thing. This is why Mr innovative has created a machine that cuts or creates surface cuts to facilitate peeling in user-defined points. The…
In the world of homebrew synthesizers, there are plenty of noiseboxes and grooveboxes that make all kinds of wacky and wild noises. However, common projects like the Auduino and Atari Punk Console are often limited in that they can’t readily be programmed to play multiple notes or any sort of discernable rhythm. Nick Poole changes…
This project aims to monitor the temperature and humidity in a room, through a compact and cheap device, powered via USB and which sends data to our smartphone through WiFi communication. The circuit consists of an ESP8266 module, a DHT22 temperature and humidity sensor and a 3.3V voltage regulator. The ESP8266 module will connect to…
In this tutorial we will learn how to register fingerprints and then read them with the biometric sensor and activate a lock. The sensor works with the serial protocol, so it can be used with any microcontroller (Arduino UNO in this case) or development card. The device also has the ability to store up to…
In this project we will see how to create a 3D printed CNC machine. It’s just a prototype, but once it’s built you will surely be able to build a larger, more accurate one. The principle will be the same, but in this case we use DVD writers stepper motors to control the motion of…
Rubik’s cubes have been mystifying and frustrating people for more than 40 years now. According to Forbes, 450 million Rubik’s cubes had been sold by 2020. But based on our very scientific estimates, only a small fraction of those have been solved. To avoid that difficulty, Stuart Gorman gave his Rubik’s cube chandelier the ability…
As Peter Balch explains, COVID-19 can sometimes give rise to cardiac complications. So, while not presented as an actual piece of medical equipment, he decided to construct an ECG (electrocardiogram) unit using an Arduino Nano for control along with an integrated 320×240 SPI display. His battery-operated device features an AD8232 heart rate monitor module to…
We’ve all played pool at least once and probably failed miserably some shots that seemed more than easy, the reaction of many would probably be a simple grimace but the Shane Wighton’s one – from YouTube channel Stuff Made Here – was to create a robotic pool cue. This idea allows him to strike only…
Microwave ovens have been the peak of convenient cooking since the 1960s, and nobody appreciates that convenience more than gamers. Normally you would microwave some pizza rolls between Call of Duty death matches, but Allen Pan decided to make gaming a more integral part of the cooking process for his most recent project. This is…
