Ferrofluid is an interesting substance that is attracted to a magnetic field. While manually playing with a flask of such goo is interesting for a few minutes, GreatScott! had other ideas. His 3D-printed rig arranges a half-dozen custom electromagnets on the side of the flask. This allows an Arduino Nano to control the magnetic field arrangement, and […]
While trying to think of his next project, Herwig Taveirne came up with the idea to craft some kind of levitating display that can showcase certain objects. Some of the criteria included completely magnetic levitation, stable floating, and overall safety since magnets can get quite hot when in use. Taveirne’s floating globe case was constructed with […]
Constructing and racing a pinewood derby car is a great way to introduce young children to the world of engineering and mathematics. Many competitions will limit how heavy a car can be to avoid unfair advantages when it comes to momentum, meaning that contestants will try to add as much weight as possible. However, the […]
We all know as makers that trying to cut those little wires to the perfect length can be one of the most tedious and frustrating aspects of soldering together a project. Whether it is because the wire cutters slipped or the lengths of the conductors are all different, the lack of consistency is detrimental. This […]
Templates are the new Arduino Cloud feature that lets you set up an existing Oplà IoT Kit project in record time, with just a couple of clicks and zero coding.
Named the grand prize winner of Instructables’ Arduino Contest, a maker known as otjones99 has created an interesting take on the classic Nerf sentry turret design by building one that uses an FPV headset to see and fire at targets. The turret consists of a turntable for moving the assembly side-to-side, along with a simple servo mechanism for […]
Studying without getting distracted can pose a significant challenge to students, which is why having small productivity hacks could be beneficial. Alexandra Charland — who goes by alch_emist on Instructables — wanted to try out the popular Pomodoro technique, which involves working for 25 minutes uninterrupted and then taking a break for five minutes after. […]
In their quest to create a portable CNC plotter, Instructables user tuenhidiy combined several PVC pieces with a couple of motors to build the P-CNC Plotter. The small machine — which was designed to resemble a quadruped robot — features an Arduino Uno and a Gbrl control shield at its heart that takes incoming G-code and translates it […]
Teleconferencing is more popular than ever, especially with the ongoing COVID-19 pandemic, but we have also seen an increase in embarrassing videos from people who were unaware that their cameras were still on. To address this problem, Charitha Jayaweera came up with a clever solution that he calls the “Present!” — a system that uses an Arduino […]
Inspired by a recent project involving Disney’s MagicBand technology, William Wimberly and Anthony Pallitta created an Arduboy-compatible RFID scanner they call the Ardumiibo, along with a DIY rumble pack. The Ardumiibo got its name from Nintendo’s Amiibo platform, which allows players to tap NFC-equipped figurines and see them within a game. In a similar manner, the […]
