WiiMote + iPhone Update

Using a Wii remote as the controller for iPhone games? Brilliant! We’ve been waiting to see some creative usage of this pairing since we covered it back in August. [ZodTTD] is the person who ported MAME over to the iPhone. Now he’s added support for the Wii remote in Mame4iPhone via the BTstack project. BTstack seeks to add Bluetooth stack functionality to devices that don’t have it or where it is limited (the iPhone).

We’ve embedded video after the break of the WiiMote used to play a MAME game. [ZodTTD] is also the author of nes4iPhone, we hope that’s the next project he will add BTstack support to!

New Wii drive hardware emulation

The Wii-Optical-Drive-Emulator (WODE) makes it possible to load Wii and GameCube ISO files from an SD card or USB storage device. This hack uses the ribbon cable for the optical drive to connect to the Wii, requiring no soldering. The WODE is based on an ARM9 processor, runs Linux, and features a backlit LCD screen and 4-way center click joystick. Storage can be hot plugged and then an ISO selected using the stick and LCD display. Selected ISO files appear in the game channel as if an original disc had just been inserted into the drive.

The developers claim that a Wii firmware upgrade will not be able to lock out the WODE. There is also a second ribbon-cable connector to use as a pass-through, giving the option to keep the optical drive hooked up if you so desire. Now the race is on for a replacement case that can house all of this new hardware and still look nice like the original. We wouldn’t be surprised to see a homebrew channel program that allows ISO selection without having to walk over to the console.

The original report (in dutch) is a dead link so here’s the Google cache copy translated. These links came via the translated Tweakers article (here’s the original Dutch). Video after the break. Don’t pirate video games!

[Thanks Roy]

Tennis practice for hackers

posted by Caleb Kraft
filed under: wii hacks

Here’s an interesting WiiMote based project. [Mans] is a tennis fan, though a bit out of practice. With the tennis season coming to a rather climactic end, he got excited and wanted to brush up on his skills. He found the toss part of his serve to be very sloppy. Being a hacker, the first thing he thought was that there must be some way of tracking and graphing his toss so that he could improve it in an intelligent and controlled manner. The WiiMote seemed a perfect fit for this. Only a small modification was necessary, an external button wired to the internal “-” button. This switch is active while he’s holding the ball, and inactive when the ball is released. In this manner, he can track and chart his toss to find out exactly where he needs improvement. He uses [Johnny Chung Lee]’s code, with a small but unspecified modification to write the accelerometer data to a text file.

As he points out, this could be very usefull for any repetitive movement. Whith accelerometers getting cheaper and cheaper, there’s nothing stopping you from using multiple ones either. Imagine a golf rig to analyze your swing, Maybe a boxing rig that measured your hip twist and arm extension, or possibly a yoyo glove to tell you if your flick needs some help. Great job [Mans].

15 ton robotic arm + WiiMote

posted by Caleb Kraft
filed under: robots hacks, wii hacks

These 15 ton robotic arms can reach 16 meters. Not content to control them by a simple joystick, the team hacked together WiiMote controls for them. Ok, we get it. Everybody loves the Wii. What is different about using the WiiMote in this scenario? You can see that they are only using the pitch, yaw, and roll. They’re not utilizing the tracking aspects at all. The only difference between the WiiMote and their joystick in this scenario is that the WiiMote connects via bluetooth. Frankly, we just like the fact that people are playing with the robotic arms, WiiMote or not.

Wii MotionPlus + Arduino

[knuckles904] was able to use the new Wii MotionPlus with an Arduino. Nintendo has released the WM+ in order to detect the motion of the controller better. The Wiimote only detects acceleration, whereas the WM+ detects rotation along 3 axes. The Arduino communicates with it over I2C, the same protocol that is used with the Nunchuk. To connect the two devices, he used jumper wires, but breakout boards are also available. He was able to create some example code with help from wiibrew.org. When paired with a Nunchuk, which contains a 3-axis accelerometer, you can have a 6 degrees-of-freedom IMU for under $40, perfect for controlling your robots or logging data.

Guitar Hero cymbal remake

[Matt] found, like many people, his Guitar Hero: World Tour cymbals left much to be desired. They were only detecting hits intermittently and starting to crack and fall apart as well. While he was waiting for his warranty replacements to arrive, he just couldn’t help by try to make his own improved version. Using about $25 worth of parts, mainly consisting of plastic plates and some neoprene material, he managed to make some pretty fantastic replacements. A video of them working might be a nice addition, but the writeup was pretty detailed otherwise.

Augmented FPS gaming

[MikeFez] sent in this info about his augmented FPS set ups. He started this project back with an original XBox in 2006. He wanted a more immersive way of interacting with his games. Pointing out that gaming visuals and interactivity have come leaps and bounds while the controllers themselves have basically just added a few buttons, he explains his goals. He wanted to have to move his body to move his character and possibly physically aim. The original project, for the XBox, was successful in that he used a floor pad to control his character. Since then, the Wii has come out and he has moved to the PC as his main platform. As expected, he is now using the Wiimote as the aiming device.

Rock band kick pedal

[Raphael] sent us this nice kick pedal mod for Guitar Hero: World Tour. After breaking his kick pedal repeatedly, he decided to build something a bit more robust. He went to the music store intending to pick up a cheap kick pedal to start with and happened to start a conversation with an employee who had a practice pad to get rid of. [Raphael] relieved him of his practice pad and promptly made a base to hold it in position. After attaching his piezo sensor to the back of it, he had a very robust kick pedal. we can’t imagine him breaking this one any time soon.

Banjo hero

We’ve posted a plethora of Guitar Hero style hardware hacks, but this one is completely different than the others. Behold, the Banjo hero. This unique controller was constructed from an old banjo and a guitar hero controller. Custom software was then built with custom songs for game play. We really wish we could see it in action. There are a couple videos available for download, but they are just pictures of the build process.
