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 […]
When wearing a face mask nowadays, you can’t show expressions in the same ways that we’re all accustomed to. As a possible solution to this problem, programmer Tyler Glaiel decided to create a custom covering with an 8×8 LED matrix that picks up his voice and imitates his mouth moving. It even allows him to […]
This article was written by César Garcia, researcher at La Hora Maker. This week, we will be exploring the Apollo Ventilator in detail! This project emerged at Makespace Madrid two months ago. It was a response to the first news about the expected lack of ventilators in Spain because of COVID-19. Several members of the space […]
The Internet has been perhaps more important than ever to keep us connected these days. Available technology, however, apparently wasn’t good enough for brothers Hunter and Josh Irving, who built their own telepresence robot using parts on-hand during their own two-person hackathon. The robot they came up with, dubbed TELEBOT, features a partially 3D-printed face along […]
How do we know that planets exist outside of our solar system? While too far away to observe directly, with extremely sensitive equipment like the Kepler space telescope it’s possible to detect changes in light as these exoplanets pass in front of a star. For an excellent visualization of how this all works, check out […]
