Let’s Melt Metals Using the ZVS (Zero Voltage Switching) Technique Applied to a 1,000W RLC Resonant Circuit Have you ever wondered how intense the electromagnetic fields surrounding us can be? This is a relevant question, considering we are surrounded by countless electromagnetic waves, caused by power distribution cables, radio and TV transmitters, mobile phone networks,…
We create NeoPixel light installations with Fishino and NodeMCU controlled via Wi-Fi from a PC or Raspberry Pi using a Python library. A few years ago, the American company Adafruit Industries transformed the LED market by introducing NeoPixels, RGB LEDs that incorporate their own controller in a single package. Adafruit aimed to simplify LED management…
The Serial Plotter in Arduino is an excellent tool for quickly visualizing serial data. However, it has a limitation that can frustrate many users: it’s not immediately obvious how to adjust the X and Y axis scales, especially the X axis. In this article, I will guide you step by step on how to solve…
Maker Faire Rome 2024 is ready to amaze the public with an extraordinary showcase of ingenuity and technological innovation, thanks to the Elettronici Entusiasti. This collective of passionate creators, through their YouTube channels and technical expertise, has captured the attention of hundreds of thousands of followers. Their mission? To rekindle interest in electronics, making, and…
Applications to MakeITcircular must be in by October 3, 2024 with the top prize of €3000 MakeITcircular is the contest that promotes the Circular Consumption Charter and the values of recycling, reuse and co-design. Shifting from a linear to a “circular economy” model is the key to enabling economic growth that respects material and natural resources and to making…
Learn More About the Ideas, Makers + Projects at Maker Faire Rome 2024 Developing a multitude of technologies for the sustainability of the planet and for environmental care is imperative today. The depletion of natural resources and the need to conserve what remains have brought technological innovation into our lives, especially at events and expositions…
We place metal foil notes on a panel and play our music by touching them, creating a melody from a truly original instrument. Those who know a little about music or have good memories of the “music education” hours at secondary school (or secondary school, to put it in a modern way), will certainly…
The initiative rewards the most innovative projects in areas related to environmental sustainability. FAE Technology will manufacture the electronic board prototypes for the top three winners. The contest is organized in collaboration with FAE Technology S.p.A. an Innovative SME operating in the design, prototyping, engineering, and production of integrated electronic solutions, announces the launch of…
Stereo power amplifier 10+10W into 8 ohms based on the integrated PAM8610, suitable for systems that require high efficiency and little heat to be dissipated. By now, the miniaturization of electronic circuits is advancing unstoppably. It involves even those devices of traditional electronics such as audio amplifiers, which do not have a strict…
Based on a single chip from Terminus, it allows you to connect four USB devices starting from a micro USB port; the form-factor is designed for pairing with Raspberry Pi Zero. We all know what a USB hub is, since at least once we all had to deal with it at home or…
Measure the quality of the air around us using a laser technology sensor that can quantify the concentration of the infamous micro-dust. Air pollution, and in particular the presence, quantification and concentration of so-called ‘fine dust’, is a very topical problem, especially in large urban agglomerations and near the large industrial areas bordering large cities….
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 crystal, it is difficult to imagine how text and numbers were displayed before their advent; Well, those who…
