Redditor “Higgs8” had a gas convection heater that is (or was) controlled manually, but they wanted something a bit more. To accomplish this, they came up with a small Arduino-based thermostat. This allows you to set the desired temperature using a potentiometer, and it senses the current temperature value via a DS18B20 thermometer unit. It then […]

Standard Arduino Nanos can be used for many purposes, but they do not feature wireless capabilities. Somehow, though, Hari Wiguna’s Arduino psychic system is apparently able to pass data between two of them. No external communication hardware is implemented, yet one Nano is able to recognize when a random number chosen on the other Nano […]

In an effort to help provide paralyzed patients with an easier way to operate their wheelchairs, these makers have developed a system that uses an OpenBCI brainwave cap to collect electroencephalogram (EEG) and electromyography (EMG) signals, literally from a user’s head. Data is then sent to a PC running OpenBCI software and passed along to […]

The lawn game of cornhole has seen a surge in popularity over the last couple of decades. But if you’ve ever thought about raising its cool factor, then YouTuber Hardware Unknown has just what you’ve been waiting for: light and audio effects that react to your throws. Hardware Unknown’s foldable boards each feature an Arduino Nano […]

Combining cosplay and actual science, as well as an origin story that entails the two, this R.A.T.I.S. (Remote Assault and Tactical Intelligence System) cyberdeck by Paul Hoets is a true retrofuturistic work of art. The build supposedly has its roots in the 1970s South African nuclear program, where it was used for radiation measurement and encrypted satellite […]

As an exhibit at the Phaneo Science Center in Wolfsburg, Germany, Niklas Roy and Felix Figus created a remotely-operated storytelling apparatus dubbed “Smart Fairy Tale.” When initiated, a little red ball rolls down the installation’s transparent tubing, triggering different interactions based on the interruption of light sensors along its path. 25 Arduino Nanos are used […]

While that plastic cup, bag, dish, or other item may have served its purpose, more than likely it could be formed into something new. With this in mind, the SOTOP-Recycling team of Manuel Maeder, Benjamin Krause, and Nadina Maeder developed an automated injection molding machine that can be built at home and is small enough […]

Have you ever wondered what your heart rate looked like when you were catching some Zs? Or perhaps you would like to check up on how someone nearby is sleeping, without actually disturbing that person. The ZazHRM monitoring system by Alan Do lets you do both, with a pulse sensor hooked up to an Arduino […]

Your heart is an amazing organ, pumping blood through your body and literally keeping you alive. However, building a realistic model of one — as explained in this write-up by Holiday McAllister — can actually be pretty simple. Here, silicone is poured into a four-inch heart mold to create the structure, partially hollowed out to accommodate a […]

Transgender Awareness Week, which culminates today with the Transgender Day of Remembrance (TDOR), aims at raising the visibility of the transgender and gender non-conforming people, and address the issues their community faces. At Arduino, we believe that technology should improve the lives of everyone, regardless of their gender, sexuality, race, age, ability, nationality, and body. Being […]
