Affordable IR thermal sensing in a compact form! You can now add affordable heat-vision to your project with an Adafruit MLX90640 Thermal Camera Breakout. This sensor contains a 24×32 array of IR thermal sensors. When connected to your microcontroller (or Raspberry Pi) it will return an array of 768 individual infrared temperature readings over I2C….
We are one of several teams who recognized the challenges faced by Italian physicians, and are working to find a solution to the anticipated global lack of ventilators. In the US alone, the COVID-19 pandemic may cause ventilator shortages on the order of 300,000-700,000 units (CDC Pandemic Response Plans). These could present on a national scale within weeks,…
“Know your enemy” is the essence of one of the most famous quotes from [Sun Tzu]’s Art of War, and it’s as true now as it was 2,500 years ago. It also applies far beyond the martial arts, and as the world squares off for battle against COVID-19, it’s especially important to know the enemy:…
We all know that COVID-19 is stressing our health system to the limit. One of the most important machines in this battle is the ventilator. Vents are critical for patients experiencing the worst symptoms of respiratory distress from the virus. Most of the numbers predict that hospitals won’t have enough ventilators to keep up…
The Tri-Color E-Ink Gizmo gives Circuit Playground Bluefruit the ability to display images on a bold black, white, & red e-ink screen. And since it’s e-ink, the image can still be seen even after power has been turned off. Even better – you can now display images on E-Ink Gizmo by sending them wirelessly from your…
The Coronavirus emergency is a real war on an invisible enemy and it is being fought on several battlefronts, first of all in the “trenches”, the hospital wards. The scarcity of DIPs (personal protective equipment), protection systems and valves for automatic respirators only cause doctors difficulties. The state intervened with huge measures but the citizens…
When I grew up we only had rotary dial phones for many years, I love them, love the sound they make and been wanting to take one and make it into a mobile phone for many years. So I was super happy when a good friend (thanks Ilanit) told me she got one for me….
We recently obtained a clock that flew on a Soyuz space mission.1 The clock, manufactured in 1984, contains over 100 integrated circuits on ten circuit boards. Why is the clock so complicated? In this blog post, I examine the clock’s circuitry and explain why so many chips were needed. The clock also provides a…
To help advance and improve access to FIDO authenticator implementations, we are excited, following other open-source projects like Solo and Somu, to announce the release of OpenSK, an open-source implementation for security keys written in Rust that supports both FIDO U2F and FIDO2 standards.

The moment we are living, in China before and all over the world now, is among the most difficult and dramatic. The COVID-19 that saw its first appearance in China, it’s also rapidly spreading to the rest of the world. Open-Electronics is a brand that is part of the group FuturaGroup, an Italian company. We…
The tutorial does not just show you how to piece the hardware and software together, it explains how each individual component works. For example, the latest installment focuses on HTML, Cascading Style Sheets (CSS), Javacript (JS), and the Bootstrap toolkit. Within the tutorial are explanations of how these markup and programming languages interact to make…
In this tutorial we’ll build a basic magnetic levitator. This guide will go over some of the theory, how to use a magnetic field sensor, and how to use one to build a basic levitation circuit. Finally, we’ll go a bit further and build a wireless power floating light. More info
