Creativity abounds in putting together this pair of Super Mario Bros. costumes. [Rob] and his wife didn’t stop with a well-assembled troupe of familiar wardrobe items, but decided to go for authentic sound effects as well. It started by finding a few of his favorite Mario sounds on the Internet. From there he grabbed a greeting card that allows you to record several message. He recorded each of the sounds and removed the electronics from the card. From there an Arduino mini was connected to the playback buttons and to a Wii nunchuck. After the break you can see that when the kids press a button, the card plays back the sound of jumping, shooting fireballs, etc. So far it’s the best use of an audio greeting card that we think eclipses its intended use.

[Deadbird] decided to use a LEGO 8880 Super Car as a host for all of his electronic tinkering. Throughout his blog (translated) you’ll find the vehicle with an Arduino MEGA interfacing various prototyping bits. It starts with the motors for locomotion, closely followed by a servo for steering. From there we see the addition of a breadboard and graphic LCD screen. So far he’s worked out the use of a PS2 keyboard as a controller and, most recently he’s interfaced a Wii Nunchuck.
We’re more used to seeing NXT kits adapted for wider use, but if you’ve got a nice kit like this one it makes a great base onto which you can add your own robotic elements.
[David Findlay] has been hard at work on his Arduino iPod remote library and is now showing off some Wii Nunchuck control in the video after the break. When we looked in on his work in September he was using a Staples Easy Button to control the iPod. Now he’s added all of the functionality for iPod simple remote mode, and most of the advanced mode.
Advanced mode works well with his iPod Photo but the iPhone just returns errors. We know that Apple uses some tricks to keep unauthorized accessories out, so we hope that [David] finds a way to sniff out the necessary accessory protocols from an approved model.

[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.
[Andy] wrote in to show us how he hacked his Pleo to be controlled by a Wii Nunchuck. He has installed Xbee units for the communication as well as written a “skit” that allows the Pleo to just stand there and wait for commands. He is using an Arduino to interpret the Nunchuck input and send it to the Pleo. It’s a pretty cool proof of concept, but the response time is pretty slow. This might be due to the Arduino’s slower serial communication rate. Yes, we said you might want to refrain from hacking them, due to their impending extinction, but did you expect us to stick to that? If you’re going to dig into one, you may also be interested in how to hack the Pleo for face recognition and remote control.
[Yezzer] has posted a video of a cool little project he’s working on. He has interfaced the Arduino and the Wii Nunchuck to control some servos. He mounted a standard USB webcam on it for good measure. There isn’t a whole lot of information, but he does include a few links to code he modified for the project. The movement is quite natural looking and seems like it would be a cheap way to get some good animatronic controls started. This might actually be a great way to control a robot for the Crabfu challenge, if they ever have another one.
Update: As [dokument] points out in the comments below, it looks like we’ve seen a set up that could be almost identical in the past.
