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.
He notes that it would be possible to use only one Arduino board for everything, but patterned his code after this tutorial that included two. The paw itself is cut out of wood and clear acrylic, allowing the lights underneath to shine through nicely.
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.
Although using the Uno in this way means that the game must be programmed especially for this type of input, Santos notes that using an HID-capable board, such as the Leonardo, would give it the capability to act as a keyboard input by itself.
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!
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.
He can now record birds as they feed without being there to scare them away!
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.
