DJ Hero Controller Gets A New Gig

Fans of the Guitar Hero etc. franchise may be interested to hear about Spin Rhythm XD, a similar rhythm game which uses a jog wheel for much of the chase-down-the-notes action. Although it can be played with a keyboard and mouse, the ideal input is a professional DJ MIDI controller — imagine two capacitive “turntables” the size of 45s, and a lot of buttons, knobs, and sliders.

Like most of us, [Dave] doesn’t have one of those. But what he does have is an old DJ Hero controller made for the Wii. It’s a lot like the big boy version of a DJ MIDI controller as far as the inputs go, except that the turntable isn’t capacitive.

Since the Wii brain is just sending I²C over a funny-looking connector, [Dave] was able to replace the Wiimote with a Teensy LC, and write new firmware for the controller inputs using a breakout board built for another project.

[Dave] tried to use as many of the DJ Hero controller’s inputs as he could, so in addition to mapping the wheel and wheel buttons to the main game controls, he wired up the joystick, effects knob, and buttons to navigate through the game menus. The game’s designers had the forethought to map these to keyboard keys, so it was pretty easy to do. He can even use dual turntables and mix or isolate them with the crossfader. Slide past the break to check out the build video, and stick around for a full-length song demo.

Are these games a little too frantic for you? Turn those ‘tables into an Etch-A-Sketch instead.

Two DJ Hero Controllers Turned Into A Giant Etch A Sketch

[Ryan] sent in a little project he’s been working on. After he got his hands on a pair of DJ Hero controllers, he figured he needed to pull controller data off them.

After plugging in his two DJ Hero controllers to a breakout board, [Ryan] discovered the turntables communicate on an I2C bus. A Teensy was thrown into the mix, and work began on decoding the turntable output. [Ryan] figured out that by pulling 23 bytes from the turn table, he was left with the necessary data. Byte 20 is the state of the green, red, and blue buttons, byte 21 is the distance traveled, and byte 23 indicates clockwise or counter-clockwise. After [Ryan] figured out how to pull data off his DJ Hero controllers, the only thing left to do was build a giant Etch A Sketch on a 55 inch TV.

By the time the Etch A Sketch was completed, [Ryan] figured out that he had a gigantic rotary encoder – perfect for some classic MAME action. He started up MAME and loaded up Cameltry and Off The Wall. The DJ Hero controllers seem to work just fine, even if the hunched-over [Ryan] can’t beat the levels.
