As entertaining as watching Netflix may be, you’re not burning a lot of calories while binging on your favorite shows. In order to do both at the same time, hacker “Roboro” modded a stationary exercise bike to stop streaming if he’s not maintaining his fitness goals. Bicycle speed is derived from the signal that’s normally sent […]
If you’ve seen color sensors such as the TCS34725, you may have considered them for projects that can pick out one colored object over another. On the other hand, if you were to take one of these sensors, mount them to an Arduino-driven plotter, and then take readings in an X/Y plane, you’d have all the […]
Steven Gioiosa recently signed up for a “Makecourse” class at the University of South Florida, where he was required to build something that featured both an Arduino and a 3D-printed part. As a fan of Portal, and especially the sentry turrets in the game, it was an easy decision to construct one of these devices […]
Whether to enhance one’s abilities or to compensate for a loss of strength due to a variety of reasons, the idea of a robotic exoskeleton is an exciting prospect. As seen here, Kristjan Berce, not content to let well-funded labs have all the fun, decided to make his own prototype assistive arm using simple hand […]
Mechanical typewriters are, for the most part, a thing of the past. Though the tactile feedback of these machines is interesting, as is the ability to directly mark on a piece of paper, they lack the important ability to input instructions into a modern computer. Konstantin Schauwecker, not satisfied with this analog-only output, decided to […]
If you work in a lab, the last thing you want is someone barging in when you’re about to complete your latest experiment or build, disturbing all of your hard work. You could use a paper note, or perhaps lock the doors, but if you’d like to inform potential disruptors of what you’re doing and […]
You can switch a tattoo machine on and off with a foot pedal, but this can be an issue when it’s time to pack it up with other gear that needs to be kept ultra-clean. To address this problem, YouTuber “Wildman Tech” made an Arduino-powered device in the shape of a beautiful wooden pyramid to control […]
With some projects, your goal is to get it working to prove out a concept for a larger project, or simply to satisfy your curiosity. On the other hand, sometimes you want your creation to look great. That was the case here, as this steampunk-inspired electromechanical clock integrates several different types of metal along with […]
After building a bicycle that could travel across town while making music, Sam Battle now taken things in a different direction. Synth Bike 3.0, which will be on display at the Science Center Dublin until September, is set up on a training fixture so that you can pedal it indoors rain or shine. This version also features a […]
Fidget spinners are currently very popular, and if you get one you’ll certainly want to spin and spin, maybe thinking you’ll never put it down. Unfortunately, like Nikodem Bartnik, you’ll eventually get bored with this device. Perhaps setting it aside forever. However, as Bartnik puts it, “Spinner has to be spinned,” so he came up with […]
