Controlling a TV with head movements

Saturday, September 16th, 2017

While most of us take being able to remotely control a television or other appliance for granted, for the millions of people with some form of disability, this can present a challenge. In order to help those with limited mobility, Cassio Batista along with Erick Campos have come up with a system that translates head movements into infrared (IR) control signals.

In the project’s video seen below, Batista shows off how he can move his head to turn a TV on and off, as well as control channel selection and volume. A webcam captures these gestures, which are passed on to a Linux-based C.H.I.P. board that translates the movements using OpenCV. Finally, an Arduino Uno receives these commands over Bluetooth and signals the TV as needed via IR. (more…)

Watch this maker cruise the beach on an electric luge

Friday, August 25th, 2017

We’ve all seen clips of people speeding down mountain roads on luges, but if landing on concrete or careening off a cliff doesn’t look like your cup of tea, perhaps something meant for the beach would be more suitable. Taking inspiration from these luges, as well as kite surfing rigs, and even Land Speeders from Star Wars, UK-based maker John Dingley came up with his Electric Beach Luge.

Foot pegs straddling a single go-kart tire in the front are used for steering the vehicle, while power is transferred to the sand by a pair of wheels in the back. A potentiometer is wired into an Arduino Uno for speed input, which uses this information to signal a 500W, 24V golf cart motor via a robot combat controller, capable of producing 160 amps continuously.

An Arduino-powered backlit Clemson Tiger Paw

Friday, August 11th, 2017

Most people support their school or favorite sports team by buying a shirt or tuning into games. Jacob Thompson, however, took things one step further and created his own Arduino-powered, backlit Clemson Tiger Paw.

Thompson’s “WallPaw,” as he calls it, uses an Arduino Uno to receive signals from an infrared remote and to pick up sounds with a small microphone. This information is passed on to an Arduino Mega, which controls a five-meter-long strip of WS2812 LEDs to provide lighting effects. (more…)

An Arduino fidget spinner arcade controller

Thursday, August 10th, 2017

Apparently unsatisfied with existing video game input devices, game designer Rob Santos created his own using, what else, fidget spinners. His system combines a spinner and five buttons on a pair of controllers to interface with Flock Off, an arcade game loosely based on Flappy Bird.

To register spinner input, a magnet is embedded on each lobe, triggering a Hall effect sensor three times per revolution when spun. An Arduino in each control box reads these signals, then sends this information, along with button inputs, to the game via USB accessible through a serial port. (more…)

This alarm clock will steal the covers right off your bed

Friday, August 4th, 2017

When you hear the words “Arduino alarm clock,” likely you think of something that uses a real-time clock (RTC) module to wake one up in a creative way, perhaps with light patterns or pleasant sounds. Though creative, the Duvet Eating Alarm Clock is not pleasant, literally ripping the covers off of your bed for a very “rude awakening.”

This project, the brainchild of YouTuber “1up Living,” uses a modified mechanical alarm clock to signal an Arduino Uno to start the duvet stealing machine. A powerful winch turns a custom-made drum that progressively wraps the bed cover around it, leaving no option but to get up and get dressed! (more…)

Start and stop an action camera with Arduino

Wednesday, August 2nd, 2017

Digital cameras have revolutionized the ways that we can record and share our lives. Action cameras, such as the GoPro and other similar models, have taken things one step further, allowing use in rugged environments. If you want to capture nature, however, you may want your camera to start recording automatically.

In order to add this ability, YouTuber “ItMightBeWorse” hooked up an ultrasonic sensor to his CA Kenai CA2001 camera using an Arduino Uno along with a transistor to act like the normal start/stop button. The output is soldered directly to the button leads, and he also tapped into the battery terminals to give himself more power supply options. (more…)

NOMNOM is an audiovisual DJ machine

Friday, July 28th, 2017

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.

The device has 16 buttons which can start and stop up to 16 clips displayed via a JavaScript web application. An Arduino Uno takes input from these buttons as well as four potentiometers to modify the clip sounds, and sends the appropriate signals to the computer running the app. There are also four knobs that control the repetition rate, volume, speed and playable length of each selected video. This enables you to make really interesting music without the normally steep learning curve. (more…)

Get into shape as you game with Cykill

Thursday, July 27th, 2017

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 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! (more…)

An Arduino-powered iris door… for chickens!

Monday, July 24th, 2017

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.

If you’d like more details on the project, be sure to check out his Instructables post! (more…)

Dual Arduinos bring this Tauren cosplay to life

Friday, July 14th, 2017

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. (more…)
