Perhaps you enjoy various flavors of electronic music, and would love to try making your own. Although this seems like a fun idea, after considering the amount of equipment and knowledge that you need to get started, many people simply move on to something else. On the other hand, the NOMNOM machine, seen here, allows you to create tunes visually using YouTube clips as samples.
If you’re having trouble finding time to work out because you’d rather play video games, then this is the solution you’ve been waiting for. The Cykill device modifies a normal exercise bike into a device that won’t let you power on your Xbox unless you’re pedaling sufficiently fast enough.
Making this even more motivating, is that if you stop pedaling fast enough, it immediately cuts power, ruining any in-progress game, and potentially even damaging your hard drive!
To implement this hack, Instructables user “Fuzzy-Wobble” used an Arduino Uno to intercept the bike’s normal control signals. From this data, as well as settings on a custom control panel, it decides whether or not to activate switchable plug that provides power to the Xbox.
There’s something beautifully sci-fi about the way an iris opens, whether as part of a camera or perhaps even as an entryway. Knowing that his father wanted an automatic chicken coop door, Ziven Posner decided to build one in the form of an iris, adding style to what would normally be the mundane task of letting the birds in/out.
The resulting iris mechanism is powered by a DC motor, and actuated by a toggle switch. Starting and stopping is controlled with an Arduino Uno, which prevents overtravel on the door via a set of limit switches.
It takes a lot to win best of show at a Comic Con, but Jason Caulfield’s Tauren Frost Death Knight named “Akulva” was more than up to the task. This beautifully detailed beast, his third try at this sort of costume, not only looks good but features backlit eyes that blink automatically, as well as a voice-changing circuit to allow Caulfield to speak in this creature’s deep tone.
The 8.5-foot-tall beast is equipped with a pair of Arduino Uno boards–one to control the eye blinking and another that uses an Adafruit Wave Shield to handle voice modulation. In addition, there’s a PicoTalk servo controller, which syncs the audio to the motor movement of the mouth.

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 for himself.
Gioiosa’s turret recreation is based on an Arduino Uno connected to an HC-SR04 ultrasonic sensor, and features motion-activated lasers that move back and forth, along with audio feedback, depending on how far away the human target is. The project also involves a bunch of servos: one to open the arms out, another to pitch them up and down, and two more to move each arm left and right.
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 tools to manufacture a bracing system over his left arm.
Control for the device, which is called “ExoArm,” is accomplished with an Arduino Uno that powers a windshield wiper motor via a driver board. As set up now, it extends via sensor input, and contracts with the push of a button.
Though it can be seen helping him lift a bicycle at the end of both of his videos, figuring out how to balance any load on the system with his actual muscle’s input is a challenge he’s still working on, but hopes to solve this issue using a strain gauge.
