Wiimote head tracking in Processing


[Manuel] has been playing around with [Johnny Lee]‘s Wiimote head tracking code. He’s posted a preliminary port outlining the code in the Processing environment. It relies on darwiinremoteOSC so you won’t see this outside of OSX, but it should help you out if you’re trying to do this is in Processing on another platform.

Easiest Rock Band to MIDI setup yet


We have news for those of you dismissing the new Wii Version of Rock Band. Sure, the lack of DLC is a huge factor, but if you’re looking to use the instruments with MIDI software, [Jordan Balagot] has found what may be the easiest way. Since the Wii instruments are connected via USB, they are easy to connect to a computer. [Balagot] used a program called junXion that is a data routing app for OS X. JunXion can take any USB human interface device and remap the buttons, making it easy to set up the drums as a MIDI input device in an intuitive way. Install junXion, plug in the drums, map the pads, and rock out.

More Wiimote hacking from Johnny Lee

Our friend [Johnny Lee] has been quite busy traveling and moving to a new city. He hasn’t had time to put together any new videos because of this. He’s been doing more Wiimote research though and has put together an extensive post about what he’s working on and thinking about.

Right before the move, he put together a demo for throwable displays. The square pieces of foamcore have retro-reflective tape added to each of the corners. The Wiimote sees the orientation of the square and adjusts the projected image to fit perfectly; even when you pick it up and throw it. He used it to add a trail to an airhockey puck. Embedded above is an earlier project where he used the Wiimote to track a foldable display and project accordingly.

[Johnny] has also been working on 3D tracking with two or more Wiimotes. Since the Wiimote is camera based, stereo triangulation is simple. Check out the video below from the University of Cambridge that uses two Wiimotes for motion capture.

Have a look at [Johnny Lee]‘s full post for even more Wiimote ideas.

Wii Menu 3.3 already circumvented


Well, that didn’t take long. Three days after the release of the Wii Menu 3.3 update (which prevents homebrew loading on the Wii by killing a special hack), the update has been circumvented. The update targeted the ubiquitous Twilight Hack, which allows homebrew software to be loaded from the Wii’s SD card slot by using a special game save. The team at HackMii were quick to disassemble, analyze, and scoff at the update, with member [bushing] quipping “we are not impressed.” The team found bug exploits for new code in the the update that cause it to ignore the Twilight Hack. They have yet to release the fix to the public, but its likely that they’ll do so at least as fast as they developed it.

Wii upgrade breaks Twilight Hack


Nintendo’s latest menu upgrade for the Wii, version 3.3, has broken the long standing Twilight Hack. In the past, you could load a hacked Twilight Princess save game to execute arbitrary code. After the upgrade, the Wii now deletes the hacked save game. The Homebrew Channel seems to have remained intact. So, if you’ve already added it and you upgrade, you should be fine. There’s no telling how long before homebrew code will be completely locked out though.

X2Wii, NES/SNES/N64 to Wii adapter


If you poke around [Raphaël]‘s site, the creator of today’s featured hack, you’ll find a lot of interesting projects. X2Wii is an ongoing project to adapt controllers from earlier console generations so they work with the Wii’s GameCube ports. He adapted his Multiuse tiny1 which uses an ATmega8. The code is all assembly so the microcontroller can keep up with the protocol. Definitely check out [Raphaël]‘s other project pages.

Wii Fit World of Warcraft


By now you’ve probably seen the video of two researchers from the German Research Center for Artificial Intelligence (DFKI) navigating through maps on Google Earth by using the Wii Fit Balance Board. They’ve gone even further now by using the board to navigate World of Warcraft. It’s obvious that the board is usable with any 3D environment. The hack is entirely software based, as the board is completely unmodified. It relays data to a laptop via Bluetooth, where the pressure data in converted to directional instructions by their custom app written in C#. No notes on the project are available on DFKI’s site, but we’re betting they’ll release the software to the public once all the kinks are worked out.
