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 […]
Arduino boards have been employed in all sorts of robotics and IoT applications, although working with air as a power source is less than straightforward. In order to make this experience easier, the Programmable-Air pneumatics kit puts everything you need for simple air power experimentation into one package. It features pressure and vacuum pumps, as […]
When you need to take a measurement for a project, there are a wide variety of off-the-shelf devices available. Or you can make one exactly to your specs, like Patrick Panikulam did with his “Digital Multi-Function Measuring Tool.” This Arduino-based gadget employs an MPU-6050 accelerometer / gyroscope that lets it act as a 2D level, […]
Off-the-shelf remote-controlled cars can be a lot of fun, but Clem decided to take things up several levels with his heavily modified rig. In the hack shown below, he outfitted an RC vehicle from the ’80s with an FPV camera, along with a MKR WiFi 1010. The WiFi-enabled MKR board was linked with a second […]
Nikodem Bartnik enjoys running, as well as making things, and he’s been able to combine both pursuits in the form of an ultrasonic race timer. The device is placed at the finish line and mounted to a tripod. Once a runner gets into position, the start of the sprint is signaled with the beep of […]
Pictures can be a great way to record an object or project, but typically only does so in one perspective. In order to capture things in three dimensions, you’ll need to be able to snap multiple photos and stitch them together with software. To take all the photos required for this process, “thomas_openscan” has come […]
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 […]
Ultrasound images are an important tool for medical diagnosis, and while units used by doctors can be very expensive, getting a basic image doesn’t have to be. Inspired by this attempt at a $500 ultrasound machine seen here, maker “stoppi71” decided to create his own using a 5 MHz ultrasound transducer via a paint-thickness gauge. […]
