Can robots paint? More specifically, can they create art? The second question is, of course, open for debate, but Technovation’s robotic build shows that they can indeed wield a paintbrush. The device, shaped vaguely like a Roomba vacuum cleaner, uses a pair of NEMA 17 motors for movement and a third to rotate a sort […]
After coming across Carbon Design Group’s Domino Wall Clock, which uses electronic magnetic coil motors to reveal white dots, Instructables member “Kothe” decided to create a simplified version of their own. The clock is comprised of three custom dominoes — the first tile for hours, the second and third for minutes. Unlike its inspiration, Kothe’s […]
If you play beer pong, whether with adult beverages, water, or soda, it’s possible you find it too repetitive or too easy. While one might see this as a self-correcting problem, to take things up a few notches Ty Palowski created a specialized table with moving cups. The custom setup oscillates the cup pyramids back […]
The Arduino Science Journal is a mobile application that allows anyone to conduct scientific experiments by measuring the surrounding world with sensors, documenting and comparing data, developing and validating hypotheses, and taking notes. The app and all learning materials are free, open source, and available for download on Google Play Store, Apple App Store, and […]
To label used bottles that would otherwise go to waste, “tuenhidiy” created a CNC plotter that itself consists mostly of scraps! The machine’s X and Z axes are formed out of a pair of old CD/DVD players, but instead of a traditional Y axis, it actuates two printer rollers to turn a bottle forwards or […]
You’ve probably seen an example of the “useless box,” or “useless machine,” which when switched on does nothing except open up to turn itself back off again. This one by creator Alex Pikkert adds a few new tricks, giving it a bit of a mood, and not one but two switches and fingers! When switched […]
We are happy to announce a new partnership with Lauterbach to provide all Portenta H7 customers with the TRACE32 debugger for free. Lauterbach’s TRACE32 debugger has been at the forefront of debug technology for more than four decades, and it is this wealth of experience and expertise that Lauterbach will draw on for the Arduino Portenta. […]
After making an indoor Executive Par 3 golf game with a ramp and cups like a skee-ball machine, creator “gcal1979” decided to add an automatic scoring system to the rig. What he came up with uses infrared break beam sensors for each of the three holes, feeding info to an Arduino Mega. Stats are shown […]
When creator mattb_138’s parents were cleaning out their house, he came across an old cassette player and decided to upgrade it with MP3 capabilities and an RFID interface. The newly-enhanced device uses an Arduino Nano for control, along with a DFPlayer Mini module to play songs stored on a microSD card. An RC522 reader enables […]
Ground penetrating radar systems, which can be used to sense the density of objects under the Earth, are normally seen as a fairly exotic piece of equipment. Naturally, such devices cost thousands of dollars. Mirel Paun’s “GPRino” prototype, though, aims to accomplish this viewing task for the comparatively paltry sum of $300. The GPRino uses antipodal […]
