Researchers across several universities have developed a controller that provides tangible interaction for 3D augmented reality data spaces. The device is comprised of three orthogonal arms, embodying X, Y, and Z axes which extend from a central point. These form an interactive space for 3D objects, with linear potentiometers and a rotary button on each axis as […]

Gregory Leveque has created an adorable 3D-printed robot that not only walks on four legs, but folds up into a ball when not in use.  To accomplish this, the round quadruped utilizes one servo to deploy each leg via a parallelogram linkage system and another to move it forwards and backwards. A clever single-servo assembly […]

3D printing allows us to make a wide variety of shapes, but adding interactive features generally means somehow strapping various electronics to them. The AirTouch project, however, presents an alternative option by enabling a fabricated object to sense up to a dozen different touch points with no components or complex calibration necessary.  Instead compressed air is pumped […]

Michael Klements’ laser-cut, Arduino-controlled “safe” may not be the most secure model that you can find, but it certainly makes for a very entertaining puzzle.  Users can place whatever “treasure” they want hidden inside, shut the door, and press a rotary encoder button to lock it via a micro servo. They then must decipher a randomly […]

Like most of us, Joey Cumeras Khan has been stuck inside for the last couple of months. As a foosball fan, this not only meant plenty of time to play with his fellow housemates but also the perfect opportunity to tech out his table with an automated scoring system. Khan’s setup works by tracking goals via […]

As an enviable senior design project at Kennesaw State University, students Tyler Gragg, Kevin Kamperman, Cody Meier, and Omar Salazar Lima created their own autonomous pinball machine.  As seen in the videos below, the table is not only nicely finished with an interesting playfield, but works quite well without human interaction. The machine’s IO system is […]

If you’ve been following the development of the Arduino IoT Cloud closely, you have probably noticed that over the months the Dashboard features have been progressing by leaps and bounds. Sure, behind the scenes there’s work being done every day, but our users need and want features that better help them manage their connected devices. […]

YouTuber “Peterbiglab” wanted an input for his DIY color-changing lamp, but didn’t want to use buttons or even have it detect claps, so he decided to make it respond to touch.  Instead of using a capacitive sensor or force-sensitive resistor, he placed a microphone inside his lamp to hear inputs. An op-amp was also included […]

Mech-Dickel Robotics has designed a beautiful quadruped robot dubbed mechDOG, which utilizes a dozen servos for motion. This gives each leg three degrees of freedom, allowing the cat-sized beast to travel a meter in 8.46 seconds. While it won’t break any speed records, creating a walking motion on this sort of unstable platform is an impressive […]

As many of us are stuck at home these days due to COVID-19, Harrison McIntyre decided to do something fun and “make it rain candy.”  What he came up with was a build that uses a flywheel to launch M&M’s — speed regulated using magnets and a Hall effect sensor, and aimed with a few […]
