Infinity mirrors, which make light appear to stretch to infinity by bouncing light between two mirrors, are incredible to observe. Hacker “Evocate” decided to go the extra mile and not only illuminate the inside of his mirror arrangement, but used an Arduino Uno and a sound sensor to enable it to react to sound. In […]
Rather than buying a coffee table, Marija from Creativity Hero decided to build her own, adding an array of 45 programmable LEDs on top of a pine base. An Arduino Mega is used to take input from 45 sensors corresponding to each LED in a grid made with MDF baffles, and commands each light to change […]
If you took chemistry at any point in your life, you were exposed to the periodic table, which organizes different atomic structures by their atomic number. It’s an amazing chart, demonstrating just how much “stuff” our world is made up of! To show off the element collection he shares with his girlfriend, elemental hacker “Maclsk” […]
While you may not give dry cleaning conveyors much thought, Andrew Quitmeyer and Madeline Schwartzman’s “Replantment” exhibition at the Pratt Manhattan Gallery uses them in an entirely new way, along with glowing silicone molds of leaves from all over the world. The machine detects when an RFID tag attached to a laundry ticket is nearby, […]
Ruben, aka “Ruubz0r,” a mechanical engineering student, was tasked with building a smart object. As he enjoys card games, he decided to make a playing card distributor. The resulting device uses a single servo to slide cards off of a deck, along with a stepper motor and ultrasonic sensor to aim it at the human recipient. […]
Tired of doing the mundane task of opening your door? This hack from Sieuwe Elferink takes care of that for you, using an Arduino Uno for control. When someone comes within 50 cm of an ultrasonic sensor attached to the door, the Arduino uses an H-bridge relay to power a windshield wiper motor, which opens […]
What do you do when faced with measuring and cutting a bunch of cables? If you’re Edward Carlson, you “simply” build a machine to do it for you! While it may not save time on this run, at least on the next occasion that he needs a few cables cut, he can just program his […]
Just when you thought you’d seen every possible hacked clock design, creator Ekaggrat Singh Kalsi has come up with something new: a faceless clock that is able to tell time with two hands that never make a full rotation. Instead, an Arduino Nano powers a novel mechanical gear assembly via a pair of motors, which causes […]
Nearly 50 years ago, mankind made the giant leap of being able to travel to the moon. To celebrate, S&T Geotronics has come of with a replica of the Apollo Guidance Computer Display/Keyboard, or AGC DSKY as it’s abbreviated. The display was prototyped on a huge breadboard assembly, along with an Arduino Mega, then finished […]
If you’re tired of classic tower building games like Jenga or stacking cards and would like a new challenge, “mr_fid” has come up with a game where you balance blocks on a tree assembly. The nicely crafted device then moves around to throw the blocks off using three servos and push rods. Everything is controlled by […]
