Wiimote controlled coil gun

iocoil1

[thecapacity] sent us his iobridge project where he controls a coil gun with a Wiimote. To make the coil gun, he took apart an office golf putter that had a ball return.  The mechanism to return the ball is a metal cylinder that is moved magnetically. He simply replaced the cylinder with a smaller diameter piece of metal to create the gun.   His computer monitors the Wiimote axis changes and sends them to the ioBridge. The unit could be located anywhere, but without a camera on it, he’ll have a hard time aiming. There’s a video of it working after the break.

ArtFall: Pachinko for techies

ArtFall allows you to draw on a whiteboard, then have small geometric shapes interact with your drawing like a barrier. Imagine a pachinko machine where you have to draw the pegs in. Not only can you draw barriers, but you can change the direction of gravity with either an iPhone or a Wiimote. The footage also shows some sound interaction as the pieces seem to bounce with the bass from some music. The effect is quite nice and somewhat reminiscent of the whiteboard pong we saw recently.

Wiimote driven motion effects

Check out the video above by [Adrien Mondot] for a extensive demonstration of eMotion being used with a Wiimote. eMotion is a physics based visual tool for the Mac. It’s designed to enhance performances by reacting to real world motion. Its grounding in physics makes the resultant motion appear more natural than if they were arbitrarily generated. The video above combines eMotion with the output of Wiimote Whiteboard, a low-cost interactive white board that uses the Wiimote camera plus IR light pens. While the video takes place in a small area, we can see how this could be scaled to a much larger space with IR lights mounted to performers.

The Hemp-Mote

hemp-mote-01

We’re sure that almost every one of our readers has been wondering why they can’t have a hemp covered Wiimote. Well, [Dhreck] got tired of waiting and made one himself. This isn’t just as simple as covering a Wiimote with hemp chord. Major modifications had to be made to keep it from getting too bulky. [Dhreck] whittled down most of the shell, then re formed it with modeling putty. After sanding that nice and smooth and applying a nice black paint job, he started the painstaking process of wrapping it in hemp.  It still works perfectly fine, but can fray if you are too hard on it. So, if you get your hands on some hemp, take it easy on your Wii.

SwiitBoard: high impact Wii balance board

swiitboard

[Frits] sent us the SwiitBoard, an improvised version of the Wii balance board. He wanted to be able to do something a little higher impact than he could on the Wii balance board, and required more space to do it in too. Using two different kinds of foam and a piece of plywood, he put together the SwiitBoard.  We’re not completely clear on how he is handling direction control. He states that it is derived from gforce.x. Can anyone clarify?  Stay tuned after the break for a video of his demo software.

Wiimote finger tracking music controller

The Evolution Control Committee has been doing live mashup performances for many years and recently upgraded their hardware. Inspired by [Johnny Lee]’s Wiimote whiteboard, they built a rear projection display they could use during performances. It displays a dense collection of samples in Ableton Live. On each of the performer’s hands is an IR LED mounted to a thimble. By touching the thumb to the forefinger, the LED turns on. Two Wiimotes watch for these IR flashes to trigger mouse clicks. [TradeMark G] found the Ableton display too complex to navigate quickly and accurately with a mouse; this new display make things much easier and enjoyable.
