Wiimote-based whiteboard lets you write on any surface

propeller_whiteboard

The Wiimote is a fantastic tool for hackers, given their affordability and how easy they are to work with. [Gareth] had a “eureka” moment while working on another Wiimote-based project, and with some alterations, converted it into an electronic whiteboard.

The whiteboard was built using the IR sensor he extracted from a Wiimote, which is wired to an EasyProp board to process the input. The Wiimote is aimed at a LCD screen, which can be “drawn” upon using a light pen he constructed from an IR led and a few batteries. Any movement of the pen is tracked by the Wiimote’s IR sensor and converted to an XY coordinate, which is then painted on the screen. The sensor has the ability to track up to four points at a time, so you can theoretically use up to four pens simultaneously.

[Gareth] points out that the sensor is not limited to tracking small displays, as the white board can be easily scaled up in size using any kind of rear projection device.

Bluetooth-enabled Wii nunchuck

wireless_nunchuck

The wireless controller for the Nintendo Wii has been used in many a hack due to its simple to use Bluetooth interface. The nunchuck portion of the controller however, has always required a physical tether to the wireless controller, or an aftermarket wireless dongle. [Rousselmanu] is looking to change that with his Bluetooth-enabled wireless Wii nunchuck. He is able to retrieve a slew of data from the nunchuck, including information from all of the accelerometers, buttons, as well as the joystick. The data is read into a PIC MCU and relayed via serial to a Bluetooth module he purchased online.

The Bluetooth module looks fairly easy to interface in Linux, and [Rousselmanu] has a video showing off how well the nunchuck can be used to interact with 3D models. He admits that the controller is a bit ugly at the moment as all the components don’t quite fit so well, but future revisions will surely remedy that.

Keep reading to see a video of the nunchuck in action.

VR! now with more kinect, wiimote, and vuzix

Those of us that remember when you could actually go to a mall and play on a VR game machine, tend to remember it fondly. What happened? The computing horsepower has grown so much, our graphics now days are simply stunning, yet there’s been no major VR revival. Yeah, those helmets were huge and gave you a headache, but it was worth it.  With the 3d positioning abilities of the latest game crazes, the Wiimote and the Kinect, [Nao_u] is finally taking this where we all knew it should have gone(google translated). Well, maybe we would have had less creepy anime faces flying around squirting ink, but the basics are there. He has created a VR system utilizing the Wiimote for his hand position, a Vuzix display for head positioning, and the kinect for body tracking. Even with the creepy flying heads I want to play it, especially after seeing him physically ducking behind boxes in the video after the break. Long live VR!

WiiMote accessibility modifications

[Catea] has put some considerable effort into making a wiimote more accessible to people with physical disabilities. He started by extending the buttons out to much larger versions mounted on a lap tray. This makes playing games much easier for those that are lacking the fine motor skills to hit the buttons on the wiimote. This alone is a pretty substantial improvement, but [Catea] wanted to do more.

Taking the whole idea further, [Catea] published a second instructible where he outlines the process of adding two Arduinos and  Xbee modulse to make the external buttons wireless.

Wiimote controlled Ruben’s tube

While we could be content following our “kiddie d-day” as [Caleb Kraft] suggested. We know you can’t continue such an awesome Friday without trying to blow yourself up first.

This Wiimote Rubens’ tube caught our eye. A PVC Aluminum irrigation pipe is drilled with holes and propane is pumped through. A speaker on one end creates changes in pressure and a neat light show follows suit. [ScaryBunnyMan] went further though, with a collection of software and a Wii Remote he “plays god” controlling the music, and thus, the fire. Check out a fun video after the split.

Wii remote connectivity for Android devices

[Pikipirs] developed an app that lets you connect a Wii remote to an Android phone. After the break you can see it used with a Sega emulator. The button presses seem very responsive, making for a nice gaming addition if you care to carry around the Wiimote in addition to your phone. It certainly seems to work better than the Wii remote + iPhone hacks we’ve seen. Pick it up from the Android store or download the APK from the thread linked at the top. This is an alpha version so don’t be shocked if it’s buggy.

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!
