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 […]
Hacky Racers, an electric vehicle racing series that’s part of the Power Racing Series, encourages drivers to put together their own hacky vehicle. While it looks like a lot of fun, in order to keep things relatively safe, current powering the car is regulated by an inline fuse from the battery, effectively limiting the top […]
If you have a broken washing machine, you may want to think twice before disposing of it. As Stephen John Saville shows in this multi-use rotary table project, they can provide a wealth of parts, from the actual physical structure/table of the build, to a motor that’s able to run via AC or DC, and […]
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 […]
Thank you for your interest! The call for volunteers is now closed. See you in San Mateo! Planning to attend Maker Faire Bay Area this month? Arduino will be joining the festivities with a booth in partnership with Microchip — Expo Hall, Area 2 — and Massimo Banzi’s State of Arduino talk on Saturday at […]
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 […]
There are a wide variety of ways to create electronic music. For a capable machine that fits in the palm of your hand and is loud enough to use outdoors, however, it’s hard to imagine a battery-powered device cooler than Bitty from Curious Sound Objects. The pocket-sized drum machine and synthesizer, currently on Kickstarter, was […]
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 […]
