While ’80s-style boomboxes have their own unique character, per hacker “Dancorp’s” excellent mod, it’s clear that they could be improved dramatically with programmable LEDs. This build uses a capacitive filtering arrangement to feed line out signals from the boombox into an Arduino Uno, which then controls three LED strips. Two of these strips are arranged around […]
Up until the present day, if you need butter, you simply ask another human to “pass the butter,” leading to minor inconvenience and awkwardness. Engineering students in Brussels have come up with a novel solution: a robot that brings the butter to you! The robot, inspired by Rick and Morty’s Butter Bot, is powered by an […]
In order to create the ultimate off-road RC rig, “asrebro” designed his own six-wheeled vehicle, operated with the help of Arduino. To give it decent range and reliability, the hacker turned to a stock transmitter and receiver, but routed the PWM signals onboard to a Mega. The Arduino uses a pair of H-bridge boards to drive all six […]
The RoboGlove project is a robotic glove by students at the Université Libre de Bruxelles that is designed to assist the wearer when continuously gripping objects. This is accomplished by a series of three servos that transmit force through cables for the index finger, middle finger, and thumb. Control is via an Arduino Uno, which […]
After finding an organ left outside to rot, hacker “tinkartank” decided to use it for his own purposes, adding push buttons under each key as inputs to an Arduino Mega. He also reused the control rods with potentiometers as a secondary input method, and added a tiny OLED to display the system’s menu. With this unique […]
If you need a MIDI device that can be programmed as your own unique light and sound controller, then Jon Bumstead’s LED Eclipse may be just what you’re looking for. The circular device, roughly the diameter of a large plate, is constructed out of 30 layers of MDF, and boasts 10 capacitive sensors made with […]
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 […]
