Cassettes (if you remember those) are normally used to play back music and other audio, but what about using an old Walkman-style tape player as the instrument itself? That’s exactly what this project by Zack Scholl allows you to do, varying the playback speed to modify pitch output. It’s a very simple setup, requiring one to hook up […]
While this project took him over 100 hours to complete, creator Whity claims that his glowing geodesic domes were worth the effort. As seen below, each dome is able to light up its triangular faces using WS2812B programmable LEDs embedded inside. The effect is mesmerizing on video, and has to be even more so in […]
While some keyboards provide media keys or even knobs to adjust your overall computer sound up and down, often what you really want is the ability to tune program volumes separately. To make this extremely easy, SNR Tech Bytes has come up with a beautifully-designed controller, which runs on the MKR ZERO. The device features five encoders […]
Clean water is one of our most precious resources, but identifying sources of pollution often means expensive equipment. This can also mean taking multiple water quality readings and somehow aggregating them together to be easily usable. As a solution to both problems, Andrei Florian has developed WaterAid — which was recently named a finalist in this […]
Would you like your own industrial robot arm, but don’t have tens of thousands of dollars to spend? You could instead build Giovanni Lerda’s KAUDA, a five-axis device that uses under 800g of PLA, an Arduino Mega, and other off-the-shelf parts. KAUDA utilizes servos to actuate the two wrist joints, along with a NEMA 17 […]
Optical media normally contains information in the form of 1s and 0s that are much too small to be seen by the human eye. This can make understanding their operation less than straightforward. To solve this problem, Jon Bumstead constructed an Arduino Nano-controlled player that uses wooden discs, with holes and solid sections large enough […]
For those with certain physical restrictions, interfacing with a computer can be a difficult task. As a possible solution, Shu Takahashi and Pato Montalvo have come up with the Magpie MIDI hands-free interface. The adaptive tool, inspired in part by a harmonica, has 13 air holes that enable its user to “sip” and “puff” all 26 letters […]
This week we are launching our Arduino Explore IoT Kit, which allows high school and college students to take their first steps in building connected devices. Educators can make a complex subject simple — explore the Internet of Things right now with Arduino Education. Aimed at the beginner, there is a complete set of easy-to-follow online […]
If you want to build your own first-person view RC rover for some backyard exploration, this design by “MoreMorris” is a great place to start. The tank-esque vehicle features a 3D-printed frame, including print-in-place tracks, and is able to traverse rough terrain as seen in the video below. Meanwhile, a servo-mounted FPV camera on top […]
According to Michael Gardi, although you can find numerous stunning Turing machine implementations on the Internet, their complexity tends to detract from the simplicity of what a Turing machine actually does. In order to easily show how they work, he decided to create a demonstrator with the actual calculations handled by an Arduino Mega. The […]
