A few months ago, maker Fabian Mazza created a CD ROM plotter for his daughters. While the three-year-old loves it, the eight-year-old thought it was too small. Rather than giving up—or building a CNC machine from scratch—he cleverly constructed a new plotter out of a Smith Corona electric typewriter. Since this device is designed to […]
Creators keep coming up with new clock designs, and while you might think that every new possibility has been exhausted, Christine Thompson has proved this assumption wrong once again with her “VFD Trilateral Clock.“ This Arduino Uno-powered device employs a stepper motor to rotate a triangular prism shape with scales for hours and minutes on […]
While you can get a very good workout on your own, it’s ideal if you have someone else watching over your form. This, of course, isn’t always practical, so researchers at the University of Auckland’s Augmented Human Lab have prototyped a wearable system called GymSoles to help. GymSoles consists of a pressure-sensitive insole that is […]
Consider an analog or even digital compass. While you can reasonably expect either to point towards magnetic north when held flat, when you add tilt and/or roll to the equation, things get a bit wonky. That is unless you’re maker “lingib,” who was able to construct a magical compass using an Arduino Uno and an […]
Arduino boards running GRBL software have long been used for CNC machine control, but usually you need to choose between having a router or laser cutter. This project, however, is specifically designed to accommodate both with a modular carriage system. Build-wise, it’s a fairly standard XYZ gantry CNC — with a frame made out of […]
If you have to do a lot of drawing on a whiteboard, you also have to clean it. Why not have a robot do this instead? That’s the idea behind Wipy, an Arduino Uno-based robot that uses magnets to stick to the board, along with grippy wheels and motors to power across your scribbles. Wipy […]
Do you like plants, but not so much tending to and watering them? If that sounds like you, then you might be interested in your own CNC growing machine. The system—created by 15-year-old maker “daily3dprinting”—is controlled by an Arduino Uno, and uses a single stepper motor to pull a watering head into position based on […]
If you want to show everyone your computer prowess—or perhaps get a little practice—binary clocks are a great way to do so. These clocks express time in 1s and 0s instead of 0 through 9, and while the concept is pretty simple, actually creating one is less than straightforward… or used to be. The Binary […]
Consider that a digital camera uses an array of sensors to capture light from an object. Maker Marcio T, however, decided to turn this idea on its head and instead utilize an array of lights that are detected by a single sensor. The way it works is that as each LED in a 32×32 matrix […]
When filming your projects—or day-to-day life—static shots can be fun, but having a moving perspective often looks even better. The challenge is keeping the camera pointed at your subject, which maker Saral Tayal addresses with his automated slider. This Arduino Uno-controlled slider is powered by a pair of brushed DC motors with encoders attached for […]
