We have news for those of you dismissing the new Wii Version of Rock Band. Sure, the lack of DLC is a huge factor, but if you're looking to use the instruments with MIDI software, [Jordan Balagot] has found what may be the easiest way. Since the Wii instruments are connected via USB, they are easy to connect to a computer. [Balagot] used a program called junXion that is a data routing app for OS X. JunXion can take any USB human interface device and remap the buttons, making it easy to set up the drums as a MIDI input device in an intuitive way. Install junXion, plug in the drums, map the pads, and rock out.
[Mark Hoekstra] is a true SGI enthusiast, and he proves it with these 3D glasses for an SGI. Taking advantage of the SGI's stereo viewport, [Hoekstra] created a controller for a pair of CrystalEyes glasses that would allow them to be used with the SGI.
[Hoekstra] used the schematic from [M.C.D. Roos]'s similar project, which used old Asus 3D VR glasses. This project can theoretically be done with any LCD-shutter glasses, the only important thing to know is the maximum shutter voltage the glasses will take. [Hoekstra] felt his way through building the board by common sense alone and somehow managed to avoid any shorts. The board only makes three connections to the glasses: an out to the left lens, one to the right, and a ground wire. After building the controller board out of an LM324 chip and a customized segment of perf board, he learned that he needed a monitor capable of displaying a relatively high bit depth at 100Hz, or 50Hz per eye. He tested the glasses with a game called Hacknoid after making a few last minute changes on the board (forgot the ground fuse), and he was soon making himself dizzy with his functioning 3D glasses.
[Jipa] over at MetkuMods put up an original re-use for old hard drives: make em into power tools. The tiny servo motor that drives the spindle doesn't generate much torque, but once the drive is spinning fast enough, the inertial force of the platter is enough to make it usable for small grinding/sanding projects. The platters are re-stacked directly on top of each other to increase strength - we'd suggest a few dabs of epoxy to make em even stronger. Once stacked, a piece of sand paper is cut to size and held on by the center platter washer. [Via hacknmod]
More Wii Fit Balance Board hacks keep rolling in from Europe. We're not sure we agree with [Juan Gonzales]'s assertion that the Wii Fit Balance board is the best way to control robots, but we can't deny how fun it looks. [Gonzales] managed to control a robot of his own design with the balance board, making it turn when he leans to the sides and moving forward and back when he leans in those directions.
The robot, which he calls SkyBot, is fairly impressive in its own right, built from a PIC microcontroller and featuring various infrared sensors and 6 contact sensors. The robot's OS can be controlled from Windows, OS X, or Linux, but for this project, they used Debian. The balance board interfaces with a laptop connected to SkyBot; custom software (tar.gz file) to make this work was written in python, and is available on [Gonzales]'s robot wiki, as well as instructions on how to build a SkyBot. It is in Spanish, however, so fire up Google Translate and get to work.
[Silverpill] sent in this interesting Super Nintendo mod. [Raph] interfaced a SNES audio processing unit to his parallel port using a logic gate and a few resistors. The project looks like it probably died off, but the goal was to use a APU to play authentic audio from emulated games. Schematics and code to get the thing working are all available on the site.
[astralpancakes] wireless arcade stick project looks like a great place to start if you want a simple project. Well constructed arcade sticks can cost $100+, but with all the MAME cabinet builders, the parts have become easy to acquire. The stick has a rigid wooden case with a metal faceplate. All of the component connections are soldered to the pads of a Logitech wireless controller. [astralpancakes] built this specifically to play Street Fighter III: 3rd Strike.
GetLoFi has always been one of our first stops when looking for circuit bending fun. Their latest project is building this simple dub siren from a noise making key chain. Dub sirens or rasta boxes are a signature sound in dub reggae. The base of this project is an eight sound keychain. Each pad is wired to an eight position selector switch. The pitch resistor is replaced with a linear pot. One push button is used to replace the original eight and another is used for mute. Plug the 1/4inch jack into a delay pedal and you're ready to rock. Check out the video below to see this particular box in use.
For $99, Apple will happily sell you a slick USB superdrive (aka DVD burner) that only works with the MacBook Air. [tnkgrl] swapped out the USB-IDE interface with a generic $9 unit to make it work with everything else. The generic board required a few mods: relocating the crystal oscillator along with the amputation of its daughter-board that carried an external power connector, usb connector and some caps.
This simple and clever guide to installing an always on USB port comes from the Team Hack-a-Day forums (originally created for the team's Folding@home efforts). [Cerberus] added a USB port to his computer case that always has power, even when the computer is off. The power comes from the +5VDC standby line in the motherboard connector. You can use this new port to charge any USB based device.
[Andrew] sent in something we've been considering for our 17 inch Dell. He squeezed a 100GB PATA notebook drive into the spare space in his Compaq laptop. He used a USB interface to provide the connection and added a toggle switch to conserve power when he doesn't need the drive spun up. The mod would be even nicer if you added a keyboard activation switch like [sprite_tm]'s keyboard light.
If you poke around [Raphaël]'s site, the creator of today's featured hack, you'll find a lot of interesting projects. X2Wii is an ongoing project to adapt controllers from earlier console generations so they work with the Wii's GameCube ports. He adapted his Multiuse tiny1 which uses an ATmega8. The code is all assembly so the microcontroller can keep up with the protocol. Definitely check out [Raphaël]'s other project pages.
Building on his USB NES pad interface, [Raphaël] released a universal USB joystick interface. It presents a HID device with four directional buttons and eight general purpose buttons. The board uses an ATmega8 and implements USB entirely in software.
The Universal PCB project lets you make any controller (specifically arcade sticks) console agnostic. A PIC microcontroller is used to translate between the button presses and the signals for the specific console you're connected to. It uses a DB15 for the external plug. The PIC knows which console you're plugged into based on which pins are high or low in your console specific adapter cable. The board includes a piggyback plug so you can plug in an Xbox360 controller board (like the one above) since the console requires authentication. The PIC's firmware is conveniently upgradeable over the USB cable.
[Mahavir] sent in his group's final project for the College of Engineering in Pune (it's over here). They built an accelerometer based Bluetooth mouse. They ended up creating a mouse that maps rotational movements to x/y motion. From the video movement, it strikes us as responding the same way that touch pointer mice do. You can hit the demo video after the break or get more details from the project page. Even if you're not into the mouse idea, you can probably learn something from their Bluetooth implementation.
Another day, another EE that refuses to play Guitar Hero properly. [Julian Bleecker] went into the design of this Guitar Hero actuator not really knowing how to size solenoids properly. Luckily, trial and error can get you a long way. The first solenoids he purchased couldn't apply enough force. The second was overkill. It was certainly strong enough but too heavy and too large to mount to the neck. The final set ended up being both the right size and working well even at 12V, half the design voltage. The elegant mounting system is what really makes this project shine. [Julian] provides the schematic for the ATmega168 driver board, which is an Arduino stripped of the extraneous bits.
