Er13k was inspired to create an Arduino music box to go along with his girlfriend’s giant stuffed dog Tobias. This eventually morphed into something that not only plays songs on its own speaker, but also lights up a 3D-printed keyboard with LEDs. Perhaps its coolest feature, though, is that it includes an RCA output jack […]
In the Harry Potter series, professor Alastor Moody is known for wearing a very distinct prosthetic eyeball that moves in a “mad” manner. When Instructables member replayreb’s son decided to go to a costume party dressed as this character, he took the opportunity to make a replica for him. The device is controlled by an […]
Andrei Erdei recently designed an amazing Arduino-powered light board, which glows and plays sounds based on the movement of a magnetic marble. First, the magnet is placed on top and then made to roll by lifting the device’s sides. An array of 36 reed switches underneath the smoked plexiglass surface detect the marble’s position, illuminating 36 […]
After mechanical engineer “Kuchbert” saw the hip-hop/electropunk band Deichkind perform — wearing LED-embedded tetrahedral hats, no less — he decided he wanted his own glowing geometric headpiece. Now, nearly 10 years and several shows later, he finally got his wish by constructing one out of acrylic triangles with 156 WS2812Bs. An Arduino Nano controls the […]
Geoff (AKA Facio Ergo Sum) has created a new take on the classic “tin can telephone,” using an Arduino and nRF24L01 transceiver to pass audio signals instead of a physical string. The build and testing process are outlined in the video below, including poking holes for an antenna and talk button, as well as hot gluing […]
If you’ve ever seen a gigantic air dancer on the side of the road and thought you might want one of your own, Davide Marin shows how to create a desktop version here. The flailing figure is constructed out of trash bags that are cut and melted into shape, and designed to stand and dance via […]
Measuring voltage with a multimeter is easy enough, and current is a bit harder, but reading both values simultaneously can be a challenge. If you’re tired of having to replug or find two meters, then look no further than Karl Kristian Torp’s palm-sized Tiny V/A. His Arduino Nano-based unit takes input from a power supply […]
Iron Man Arc Reactors have brought joy to makers of all ages, whether as something cool on a movie screen, as a hacked together light assembly, or even a cosplay prop created from a DIY kit. Michael Klements decided to turn one of these kits into something more, by hooking it up to act as a […]
If you grew up watching Honey I Shrunk the Kids, you may recall the scene with Wayne Szalinski’s remote-controlled lawn mower. Inspired by the 1989 film, “elliotmade” designed a version of his own a few years ago that’s still functioning today. With a successful proof of concept, he decided to assemble a second version featuring some […]
If you want a virtual reality headset for your computer, but don’t want to dig deep into your pockets, this project by “jamesvdberg” (AKA Killer Robotics) presents a low-cost alternative. Although it won’t pack the capabilities of an Oculus or HTC Vive, jamesvdberg’s VR rig can be replicated for just $80 using a Google cardboard-compatible shell, along […]
