If you want to build RC airplanes, you’ll need a way to make lightweight wings. 3D printing can work with foaming filament, but most 3D printers have limited build volume. A better method is to use a hot wire cutter to shape foam. Michael Rechtin’s CNC hot wire cutter automates that process across four axes, […]
There was a time when computers were exciting and fun. Now most of them feel like commodity appliances — no more interesting than a washing machine or a toaster. Joe longed for the good ol’ days of 8-bit personal computers, so he used a trio of Arduino development boards to design his own “fantasy computer.” […]
Carlo Prisco and Fabio Marchese from PriscoZen had a clear goal from the start: not a technical demo, but a real, working platform that could bring machine control, software logic, and visual quality inspection together in a single compact system. Something they could demonstrate live, evolve over time, and show that industrial automation doesn’t have […]
A single microcontroller can interface with many other components and handle several different tasks — that’s kind of the whole point. But microcontrollers do have limits and sometimes it makes sense to divvy up tasks to get a logical system architecture. That led Michael Rigsby to put a whopping 11 different Arduino boards into his […]
There are industrial robots, and there is Brian Brocken’s two-ton behemoth: an ABB IRB6400 capable of moving at least 150kg (330 pounds), thanks to partial hydraulic actuation. It is an absurd robot that a factory might use to put small engines in cars. So, it is an understatement to say it was overkill when Brocken […]
Brian got his hands on an old Lorenz 15 teletype machine, which was made in the 1950s. He also managed to snag an appropriate teletype modem. But the modem couldn’t seem to understand recorded teletype messages, so Brian used an Arduino Mega 2560 to “speak” teletype and get the Lorenz 15 printing. You can think […]
When Vitor started building his humanoid robot a year ago, he didn’t have any specific application in mind. He just knew he wanted a robot and figured he’d find a use for it later. Well, he finally gave that robot a purpose by converting it into a bartender. The original robot looked like the sort […]
Tactile displays — particularly for use as refreshable braille displays — have always been a challenge to design and fabricate, as they require so many moving parts. Every dot needs its own actuated mechanism and there needs to be dozens or hundreds of dots squeezed into a small space. Conventional micro actuators become very expensive […]
We’re used to interacting with electronic technology that is cold, rigid, and overwhelmingly artificial. The device you’re reading this on doesn’t resemble anything found in nature and, consciously or not, you see it as something separate from the natural world. But what if the dividing boundary was less distinct? How would that affect the way […]
The population of the world is currently in an uproar as everyone panics about AI stealing jobs. But nobody seems to be concerned about the possibility of plants stealing video games. Nobody, that is, except a team of researchers from KAIST and the Royal College of Art, who decided to just go ahead and make […]
