Morse code input for Android with Arduino

Morse code input for Android with Arduino

Morse code may not be as widely used as in its heyday, but it still certainly has its adherents. One avid user is Tanya Finlayson, who has been using this as her method of communication for roughly 40 years. Now, with the Gboard phone keyboard supporting input via dots and dashes, the world of Android […]

Camera questions user, saves photographic response

Camera questions user, saves photographic response

Cultural probes aim to elicit unique responses by asking people to respond to a question, many times in the form of a photograph. While disposable cameras once worked quite nicely for this purpose, their relative rarity today meant a new digital alternative was needed. For this, Interaction Research Studio came up with a series of […]

Audio preamplifier with tiny OLED display and unique case

Audio preamplifier with tiny OLED display and unique case

As spotted here, Sam Izdat decided to make a preamplifier for a friend who provides voice talent for audiobooks and the like. The primary audio circuitry for the build is provided by a purchased PCB based on the INA217 chip from TI, but from there things get a bit more interesting. To complete the project, […]

Robot transforms to slide under doors and more

Robot transforms to slide under doors and more

While the STAR, or Sprawl Turned Autonomous Robot, is more than capable of traveling over obstacles with its three-pointed wheels, it can also make itself thin enough to simply slide under others as needed. This clever design uses an Arduino Pro Mini for control, and normally moves around like a tank, rolling on six wheels […]

Tell time on a three-module voltmeter clock

Tell time on a three-module voltmeter clock

Father’s Day 2018 has come and gone, but it’s never too early to start planning for next year. As seen here, Michael Teeuw decided to build a clock out of three analog voltmeters for his dad in 2017. After getting sidetracked last year, he was finally able to complete it on time for 2018! Teeuw’s […]

Track the sun with this Arduino-based solar panel

Track the sun with this Arduino-based solar panel

Solar panels are a great way to produce power literally out of thin air, but how much power they produce depends, in part, on how they are aimed. In order to figure out just how much better his solar setup could be with active tracking, YouTuber GreatScott! decided to test this by creating a miniature […]

Nature and Arduinos combine as binary driftwood alarm clock

Nature and Arduinos combine as binary driftwood alarm clock

Binary clocks, which use a series of dots to indicate the time, are nothing new, but you’ve never seen anything like this device by Matt Wos!  Wos’ project features a beautiful driftwood base, and WS2812B RGB LED dots that are suspended above it with copper wire to show the time. Inside are a pair of […]

Novel lathe control method with Arduino

Novel lathe control method with Arduino

If you want to work with round parts, a lathe is the tool to have, but takes some time to master. A full CNC version takes even more time and skill to understand, but mechanical engineer “Wade’o Design” has come up with something in between. Instead of running his machine with code directly, his device […]

Arduino goes to summer school in Costa Rica!

Arduino goes to summer school in Costa Rica!

Back in April, the Arduino team ran a physical computing workshop as part of the summer school program organized by the Copenhagen Institute of Interaction Design. Each workshop was taught in the context of the United Nations Sustainable Development Goals. The one-week long class focused on designing physical and interactive objects that can help kids […]

Bucky Glow is an Arduino-controlled LED dodecahedron

Bucky Glow is an Arduino-controlled LED dodecahedron

After successfully building a gigantic geometric interactive light structure, Jonathan Bumstead decided to do things in a more approachable manner, creating a more a reasonably-sized dodecahedron controlled by an Arduino Nano. The device, named “Bucky Glow,” uses 11 RGB LEDs to light up each side with the exception of the bottom pentagon section. While it […]
