When Hunter Irving spotted a knockoff Thomas the Tank Engine toy at a thrift store, he simply had to buy it, telling himself that he’d turn it into an animatronic contraption at some point. While these kind of promises often go unfulfilled, Irving converted it into an egg-shaped, karaoke-singing robot, with a mouth and eyes […]
Does a rocket need to use a certain type of fuel, or even be capable of spaceflight? While James Bruton’s build might not fit everyone’s definition of this type of craft because of its electric ducted fan (EDF) propulsion, it does face the same major challenge of controlling a tall pipe-like structure from thrust coming […]
Split-flap displays show information using characters changed by an electric motor. While they’ve largely been replaced by more modern means, hobbyists like “gabbapeople” have been keeping this this technique alive, in this case as a four-character IoT weather display. The device is built using laser-cut plexiglass, and uses four individual servos to actuate the character […]
When you want to make a mobile robot, DC motors can be a great choice. We normally accept that they can be purchased for a few dollars each, but what if you want to make your own? In order to assist with the winding process for a self-built—or at least self-wound—motor, Mr. Innovative created an… […]
According to this project’s write-up, while some struggle to get enough nourishment, those in more developed countries often aspire to consume too little food. As an apparent commentary on this situation, Niklas Roy and Kati Hyyppä have created a mechatronic game called J’ai faim!, French for “I’m hungry!” In this Arduino-controlled game, participants rotate a […]
Need a wave generator to test out your latest boat, barge, or submarine design, but can’t quite afford one? If so, then you might consider Subham Bhatt’s DIY tank that he was able to construct for around $1,200 USD. Bhatt’s device features a pair of stepper motors and lead screws that push a stainless steel […]
Today, if you take a photograph, more than likely it’s digital. This presents many advantages over its film counterpart, but many serious photographers still use the format in order to produce just the right effect. Pablo Zárate is one such photographer, and combined this passion with Arduino and 3D printing knowledge to produce the “Develophead.” […]
Annelle Rigsby found that her mother, who suffers from Alzheimer’s, is delighted to hear familiar songs. While Annelle can’t always be there to help her enjoy music, she and her husband Mike came up with what they call the Notable Board Book that automatically plays tunes. The book itself is well laid-out, with song text and […]
Flament bulbs, commonly known as Edison bulbs, contain a variety of interesting LED lights. So interesting, in fact, that maker Andy Pugh decided to take these individual components up and turn them into a 7-segment display clock. While making a clock isn’t an uncommon hacker pursuit, this Arduino-controlled device uses a series of wires to […]
Arduino boards and custom clock builds seem to be a great match, as illustrated by Görkem Bozkurt’s recent project. His 3D-printed marble clock uses a stepper-driven gear mechanism to lift 11mm steel spheres to the device’s top chute. The spheres then roll down to a five-minute rail, which empties when filled and transfers a single […]
