If you don’t want to carry keycard or memorize a passcode, this build from Electronoobs might be just the thing. The system uses a fingerprint reader to check to see if you have access, and if approved, the device’s Arduino Mega unlocks the theoretical door using a micro servo motor. Three push buttons and a […]
Playing music well can be difficult for anyone, especially those with certain disabilities. To make this form of self-expression easier for everyone, Alessandro Verdiesen and Luuk van Kuijk built the Airdrum—an IR sensor-based instrument that is played simply by the wave of a hand. The Airdrum uses six individual sensor boards to detect when a […]
Are you still pushing buttons and adjusting knobs with your fingers to brew your favorite coffee? If so, then this voice-controlled solution could be the next project on your list. To accomplish this hack, a rather high-end coffee maker was disassembled and modified, adding an Arduino Nano to press buttons, along with a small motor […]
If you want to know the tide in your area, you could look it up in the paper, on the Internet, or using an app, but this moon-shaped tide clock provides a unique way to see what’s going on at a glance. The 3D-printed device uses an Arduino Nano for processing, along with an RTC […]
Those that need a text entry method other than a traditional keyboard and mouse often use a method where a character is selected, then input using a sip or puff of air from the user’s mouth. Naturally this is less than ideal, and one alternative interface shown here is to instead use sip/puff air currents to […]
LEGO sets have long been able to work with simple pneumatic controls, but what about a full air compressor built out of these components? Would this be possible? As demonstrated in the video below, this can in fact be accomplished, and in brilliant style no less. The design uses four motors, eight pneumatic pumps, and […]
After finding a broken lamp at a scrapyard, which as meant to throw light both up and down, “tuenhidiy” decided to fix it. However, instead of using the normal two-bulb configuration, he replaced these lights with 64 individual RGB LEDs. The results are beautiful, as seen in the videos below. Interestingly, this maker didn’t use […]
If you need a certain electrical signal for testing, there are a variety of function generators available at a wide range of prices and capabilities. If, however, you’d like to build your own, this project by maker “Faransky” looks like a great place to start. An Arduino Nano forms the core of this device, which […]
In nature, animals often are sensitive to the outside environment, retreating into a hole, shell, or other protective structure upon sensing sudden movements. If you were to envision this kind of behavior in robot form, you might come up with something like “The Shy Machine” from Daric Gill Studios. When it detects motion via a […]
If you’re a fan of Portal games, you’d probably like nothing more than to have your own Wheatley Personality Core to accompany you on real-life adventures. While that would be a passing thought for most, Luke Albertson has created his own amazing replica of the Portal 2 character. The device not only can say over […]
