Arduiono+Wii fit

Arduino+Wii fit

This is a simple robotics project, but with great potential  and lot of fun, the only drawback is that you need a Wii fit or Xbox360 game controller, the rest is affordable. The Wii fit stepper plate position is interpreted by the Arduino board and sent to the servos, basically you control the labyrinth game with your foot.

I think that the project can be easily developed further, you can make a replacement hardware for the Wii fit, and the wooden game can also be customized, there are many possibilities to expand, maybe you will attach a webcamera and make an intelligent robot which solves the puzzle by itself.

DIY Wii game system

DIY Wii game system

At first glance it looks really silly, but after further investigation it reveals itself as a really complex and carefully designed stand alone game console. The wood box contains accelerometers, color LCD display, the ATmega32 based electronics, buzzer, and to keep things simple two user buttons.

The game is controlled via the two buttons and the tilt of the box, very similar to the well known Wii made by Sony, the major differences are that this is a stand alone unit and its price, the author kept the costs under 60$, he used sample parts for the accelerometers but anyway it is cheap.

The power is taken from a 9V battery, but as you may think the LCD and the sensors drain the battery really fast, so maybe a larger rechargeable battery pack should be used of at least 1500mAH capacity.

The entire project documentation is made public, well documented software written in C. It is a great project which handles graphic LCD display and real-time execution, the fact that he uses the ATmega32 which has free C compiler puts the cherry on the cake. The software could be optimized in some parts, like the SPI handling which is made in software, the schematic is only block level, so if you want to replicate this project you must have some experience in the field.

How to install a WIIKey Modchip

Every gadget gets hacked sooner or later, it’s just the way things go. Some people get bored and can’t help themselves not hacking something to make them different, unique. In this case, you’ll be learning how to install a Wii modchip.

The WiiKey modchip doesn’t actually go on the Wii’s motherboard, but the DVD drive’s motherboard, effectively sitting between the DVD subsystem and the Wii’s DVD interface, and it tells the Wii that any disc inserted into the drive is an authentic disc of that Wii’s region. The Wii never suspects that the DVD drive is lying, and that’s why the modchip allows you to play backup up games, homebrew, and so forth.
