GSM/4G Remote Control with DTMF Commands
Two-way remote control system, based on the GSM/4G A7682E module from SIMCom, which utilizes the GSM network for activations and controls. All settings are made via SMS or locally via PC (using the optional FT782M interface). It has two relay outputs with monostable or bistable operation and two opto-isolated alarm inputs. It can store up […]
Application For Maker Faire Rome 2024: Deadline June 20th
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 [
Power supply latch
This power supply latch provides power to the external circuit you wish to power, allowing it to remain powered on or turn off after completing its operations. It functions like a self-holding relay but is solid-state and is suitable for handling a wide range of DC voltages from 5 to 30 volts. It is ideal […]
ESP32 Low Power Module
ESP32 Low Power Module, based on Espressif’s SoC capable of providing full compatibility with the standard MINI ESP32 version. Compared to the latter, this module lacks a USB interface, dedicated exclusively to programming the ESP32, making it ideal for low-power applications. Compatible with the Arduino IDE, it includes a WiFi 802.11 b/g/n transceiver and a

How to Adjust X and Y Axis Scale in Arduino Serial Plotter (No Extra Software Needed)
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 […]
How to Control NeoPixel Installations via Wi-Fi Using Fishino and NodeMCU with Python
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 […]
How to Build a 1000W ZVS Induction Heater Using a Resonant RLC Circuit
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 p
How to Build a Variable Constant Current Source with Sink Function
An adjustable constant current generator is an essential tool for many electronic applications, especially when a stable current is required regardless of the load. This project, designed and built with a PIC16F1765 microcontroller, combines both constant current sourcing and sinking capabilities in one device, with the ability to adjust the value from 0 to
TekkaSketch: Reinventing the Etch-a-Sketch with E-Ink and ESP32 Innovation
The iconic Etch-a-Sketch, a toy beloved by generations, always had one major limitation: a drawing mistake meant shaking the entire device and starting over from scratch. With the TekkaSketch project, this limitation is overcome thanks to a modern approach that integrates digital functions while preserving the classic aesthetic. The idea stems from observing
