If you are into music and like to hack your Wii have a look at this Wiimote AirDeck Virtual Theremin project. It allows you to get your DJ on and bust out some tunes.
“Here is some video I shot shortly after my project presentation which demonstrates the AirDeck virtual theremin application I designed and explains some of the features. It uses the Wii remote as an input mechanism by tracking motion with Infrared LEDs. The AirDeck is written in Java with the WiiUseJ API for handling Wii remote events and the JSyn API for internal synthesis. It can control MIDI out as well as offering a simple DJ scratch interface for real-time manipulation of sound samples similar to a DJ scratching with vinyl records.”
Here is another example of where the inexpensive Wiimote controller with all of its built in sensors nicely adapts itself to an other application. In this case the wiimote is used to determine how good a tennis serve is!
“Well that sounded like a plan so I poped open my wiimote soldered in a few wires to the minus key and then taped the wiimote to left arm (I am right handed).
Then I taped the other end of the wires to my thumb and wrapped a tennis ball in aluminum. So now when I had the ball in my hand it completed the circuit and pressed the button which registers the data in the software. I then toss the ball and when it leaves my hand it unpresses the button stopping the registry of the data from the accelerometer.”
Matt Cutts has developed a python program that allows a Linux computer to connect to a Wii Balance Board via blue tooth and display the results graphically in real time.
“Each sensor returns 2 bytes of data and also has six bytes of calibration data. Think of it as a 16 bit number and three calibration numbers, that are also 16 bits apiece. The three calibration numbers correspond to the sensor reading for 0 kg, 17 kg, and 34 kg (those numbers should look familiar if you look at the previous paragraph). So if sensor #1 gives a value of 5725 and the 34 kg number is also 5725, then that sensor is reporting exactly 34 kg of weight on it.”
Here is a cool way to control your Webcam! With a flick of your wrist this camera is moved to the location you want. If you want more have a look at this other project that does something similar.
We have see the cool head tracking using the wiimote that Johnny Lee designed. Mediacreator has taken that lead and took it farther. Now with either a stereo TV or some 3D glasses you can see the actual depth of the rings. I can’t wait to see what type of games use this technology!
“We were inspired by Johnny Lee’s Youtube movie about VR Head tracking with the Wii Remote. We thought it would be cool if Johnny’s concept could actually be shown in stereoscopic 3D.”
What better way to drive your self balancing robot than a Wiimote. That is what Ara Kourchians decided to do. See the video below for a demonstration of the self balancing aspect however it unfortunately doesn’t show the Wii remote control. We will have to wait for an update to the
“The Segwii is a self balancing robot that is remotely controlled by a wiimote. The goal of this project is to educate robot enthusiasts, share ideas, and to improve on designs. There are many things to learn and help out in, including open source software and hardware, complementary filtering, PID (Proportional Integral Derivatives), and embedded systems programming.”
The Neuros system now has Wiimote support! Have a look at it in action after the jump.
“As most of you know, the LINK started out life as what we call a “TVPC,” namely a disc-less, quiet computer that’s configured specifically for bringing Internet video to the tv. From that foundation, it’s rapidly evolving to provide a more seamless couch experience. One area that’s receiving a lot of attention is the controller.
Recently, we’ve been spending some time prototyping with motion sensing controllers, including the Nintendo wii controller. The significant thing about this kind of interface is that it allows an easy way to have both standard menu navigation (up down left right) as well as free form mouse control, which is still needed for web browsing. There’s even a virtual keyboard
(which we certainly won’t use in production).”
Here is a cool use for the Wii Balance Board. In this application it controls the labyrinth just like you could do with a joystick.
Video after the break.
“Currently the game is using two servos and an Arduino to turn the knobs that move the game surface. I bought my Labyrinth game at a Tuesday Morning store for less than $10. The servos were about $10 each and my Arduino cost around $30. I often use the AdaFruit BoArduinos in the robotics workshops I teach which cost $17.50 so that could reduce the overall cost to build this project.”
This cool hack allows you to enhance the function of your Wii by playing the drums on it! The Wiimote accelerometers are used to read in the user gestures and turn it into music.
“Wii Drum High integrates all three kinds of Wii controllers to stimulate a complete drum set of Hi-hat, Snare, Base drum, Crash cymbal, Ride cymbal, Mid tom and Low tom. Up to 4 sets of Wii remote and nunchuk can be used at the same time. (one of my colleague succeeded in connecting 5 wiimotes to a PC, but I’ve never tried)
This software is written in C# and utilizes Windows Presentation Foundation (or WPF) within .NET Framework 3.5 for user interface and animation. The data from wii controllers is collected using Brian Peek’s WiimoteLib API, and sound is programmed with DirectSound.”
