Let’s describe the firmware of the stepper motor feedback controller and test it on the 3D printer. (Read the first post) In the limits of non-retroactive stepper motor control is that in applications for the drive of...

Controller with stepper motor feedback able to dynamically check the shaft positioning and prevent possible step losses. Who has never happened to launch a complex and long 3D print, maybe a job of hours or dozens of...

Innovation and the general public in contact again! Thanks to the constant progress of the vaccination campaign, “Maker Faire Rome – The European Edition“, the biggest European event dedicated to innovation, promoted and organised by the Chamber...

We create the instrument that the reports have brought in vogue, but that for years has been used in hospitals and in sports medicine to verify the degree of oxygenation of the blood. The Coronavirus epidemic that...

8 relays controlled by 8 opto-isolated digital lines or by Raspberry Pi. It’s not the first time that we propose a relay board, because in these pages you have found both generic control boards that can be...

Getting to know and evaluate the software offer for PCB, in order to choose the best one for our needs.   Designing an electronic board is a considerable and varied effort, both in terms of board design,...

  It automatically supplies meals to your pet at preset times, by providing the daily dose of cat kibble. Having a pet involves big responsibilities, first of all granting them food; unfortunately, a hectic lifestyle and imposed...

Identify faces in a video or live shot and recognize if they are wearing a mask: easy with the “raspberry”. The spread of COVID-19 has created a global health crisis that has had a profound impact on...

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...

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...

Connected to the USB port of a computer, it allows you to simultaneously control four dual-channel infrared receivers of the POWER FUNCTIONS LEGO® series through simple serial commands. A few years ago LEGO®, manufacturer of the most...

We ensure social distancing with an audible and visual beacon that alerts you when you’re getting too close to a store counter, kiosk or counter. Since the “restart” after COVID-19 and the various Phase 2, Phase 3...

Let’s combine the Fishino UNO power with the convenience of Google Home voice assistants, so that we can forget about the remote control and manage various devices with simple phrases. With this project, we are going to...

  Disinfects masks and objects by exposing them to ultraviolet rays generated by innovative UVC LEDs, protecting them from viruses and bacteria. In all situations where it is necessary to sanitize, sterilize and otherwise disinfect objects potentially...

The sensors and electronics needed to measure the weight of objects in many areas, from electronic scales to industrial weighers. When we talk about measuring the weight of an object, we mean the detection of the force...

We build a Fishino-powered weather station that allows you to collect data from sensors, view them in real-time, send push notifications and save data at regular intervals. We cannot deny that the occurrence of extreme weather phenomena...

Let’s build the Dashboard to optimally manage our network of IoT Antennino devices connected through the dedicated Gateway module. After having described the hardware gateway for the Antennino modules and having combined it with a Dashboard based...

  Self-learning UHF receiver consisting of a radio receiver board with Motorola decoding and a module equipped with 8 relays operating in impulse or bistable mode. In many home automation applications and in general where it is...
