Did you know that embossing machines needed to generate Braille characters can cost thousands of dollars? After finding this out, hacker Carlos Campos decided to design and build his own using 3D-printed parts, along with an Arduino Mega and a RAMPS board for control. Instead of punching each dot, the device pushes a pin out […]
If you thought the power of levitation was only available to magicians (and perhaps magnets) then check out this amazing project from Asier Marzo. It uses an Arduino Mega to control an 8×8 array of ultrasonic transducers, which when carefully coordinated using a simulation program, not only can suspend a particle but cause it to […]
While it can be difficult to get enough sleep, at least you can try to make it as restful as possible when you are in bed. That’s the idea behind this project by Julia Currie and Nicholas Sarkis, who developed an Arduino Nano-based sleep monitor for their final ECE 4760 project at Cornell. The bulk […]
If you’d like to create your own simulated guitar from scratch, you’ll want to check out this project by Cornell ECE students Jake Podell and Jonah Wexler. It uses four conductive strings on the neck to sense which note is selected, along with a pick wired as input to tell when the string has been […]
If you want to create your own custom PCBs, you could design it and wait for a fab house to send it back, dealing with any errors, or you could do it yourself. Hacker Andras Kabai decided to go for the second option, and made his own UV exposure tool to help him with the process […]
Participating in Reddit’s Secret Santa this year, hacker “Haxxa” decided to go all out, picking out not only several gifts for the recipient, but an Arduino-powered trivia box to house them in. In use, an Arduino Nano onboard feeds queries to the gift recipient on an LCD display, allowing them to answer using one of three […]
As reported by the Creative Applications Network, “Tangibles Worlds explores the effects of tactile experience as a catalyst for full immersion in VR.” The project by Stella Speziali takes the form of three separate boxes, along with an Oculus Rift headset. When a hand is placed in one of these boxes, the user is virtually transported […]
While you may question if some of the blinking lights and buttons in science fiction movies actually do anything, you’d still really like to hit those buttons just to see what happens, right? If that sounds like you, then something like this rocket ship panel from maker “r570sv” might be just the thing for your […]
If you’d like a rebel fighter pilot suit, complete with the automated chest box, then look no further than this excellent build from “badjer1.” It features a chest box with the same dimensions seen in the movies that lights up randomly, and even allows bored pilots to play a game of Pong on its double-LED […]
If you have a trash can with a lid, you’ve probably accepted the small inconvenience of opening it with your hand and foot. YouTube hacker MadGyver, however, came up with a different solution using an Arduino Nano and a micro servo to open the lid whenever someone places a hand near the unit’s ultrasonic sensor. […]
