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.

[ZodTTD] has released a Nintendo 64 emulator for iPhone. It is available (for a price) at the Cydia store and can be installed on jailbroken iPhones. The video shows Wii Remote support as a control interface that uses both buttons and the accelerometer, an addition since we last looked at his work. There is no word about nunchuck functionality, a must if you’re going to try to 100% Mario64.
Yo dawg, we heard you liked accelerometers… Apparently people have been wanting this for a while. We’re not completely sure why, so we’ll wait and see what gets done with it. [Ubiq_01] has connected a WiiMote to his iPhone and is using it to control and OpenGL application. He has released a tutorial (which seems to be down currently) if you want to try to reproduce it yourself.
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.
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].
[Matt Cutts], head developer for google’s anti spam team, describes how to attach a Wii balance board to a linux computer. He even shows how to make a GUI to show the input. The entire project is done in about 200 lines of python.The process assumes that you can already make a bluetooth connection to a WiiMote, but if you can’t, he’s got instructions for that too.
[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.
