DJ Hero Controller Gets A New Gig

February 24, 2020 by 2 Comments

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.

Up Your Game With DIY Headset Motion Tracking

February 2, 2020 by 5 Comments

While there’s been a lot of advancements in VR gaming over the last couple of years, plenty of folks are still happy enough to just stare at their monitor. But that’s not to say some of those fancy head-tracking tricks wouldn’t be a welcome addition to their repertoire. For players who are literally looking to get their head in the game, [Adrian Schwizgebel] has created qeMotion.

The idea here is simple enough: attach a motion sensor to a standard gaming headset (here a MPU-6050 IMU), and use the data from it to virtually “press” keys through USB HID emulation. Many first person shooter games offer the ability to lean left or right by pressing Q or E respectively, so all [Adrian] had to do was map the appropriate accelerometer readings to those keys for it to work seamlessly with popular titles such as Tom Clancy’s Rainbow Six Siege and Insurgency.

The concept might be basic, but the execution is anything but. Rather than just duct taping an Arduino to his headset, [Adrian] designed a very slick 3D printed enclosure for the electronics that sits on his desk. While they haven’t all been implemented yet, the devices features indicator lights and buttons to switch through various modes. The sensor on the headset has similarly been encased in a very professional looking 3D printed box, complete with a nice braided cable to link it to the desk unit.

It’s been awhile since we’ve seen a head tracking project, and most of those utilized something like the Wii Remote. Adding sensors to a person’s head normally wouldn’t be an ideal situation, but if you’re going to be wearing the headset anyway to listen to the game and chat, it’s not really a problem. If your hair is too nice for the qeMotion, you could always try doing something similar with computer vision.

Building A Limitless VR Desktop

December 21, 2019 by 44 Comments

[Gabor Horvath] thinks even two monitors is too little space to really lay out his windows properly. That’s why he’s building a VR Desktop straight out of our deepest cyberpunk fantasies.

The software runs on Windows and Android at the moment. The user can put up multiple windows in a sphere around them. As their head moves, the window directly in front grows in focus.  Imagine how many stack overflow windows you could have open at the same time!

Another exciting possibility is that the digital work-spaces can be shared among multiple users. Pair programming isn’t so bad, and now the possibility of doing it effectively while remote seems a little more possible. Even pair CAD might be possible depending on how its done. Imagine sharing your personal CAD session on another user’s screen and seeing theirs beside yours, allowing for simultaneous design.

Overall it’s a very cool tech demo that could turn into something more. It makes us wonder how long it is before tech workers on their way to lunch are marked by a telltale red circle on their face.

Prototype Proves Wii Was Two Gamecubes Taped Together All Along

October 29, 2018 by 26 Comments

Say what you will about Nintendo’s little purple lunchbox, the Gamecube, but it was home to many delightful experiences from Super Smash Bros. Melee to The Legend of Zelda: Twilight Princess. We now know it was also home to one of the very first Nintendo Wii remotes as well thanks to the recent listing from [Kuriaisu1122] on Yahoo Auctions.

The prototype Wii remote is a wired design and features a proprietary Gamecube controller cable. Notable differences include the two buttons toward the bottom are labeled ‘B’ and ‘A’ respectively. This shows that Nintendo always intended to have players hold the remote sideways in order to play Virtual console games. The large white button next to the directional pad is unlabeled, and along the middle are the traditional ‘Start’ and ‘Select’ labels on either side of ‘Home’. However, these all would go through multiple revisions on the way to the final design. Interestingly there is an Ethernet jack at the base used to connect accessories. That connector would eventually become the often maligned “Nunchuk interface”, but what modder wouldn’t have loved it if that Ethernet port had carried on to the final design?

Much like the “invaluable” Mario Party 6 microphone, the prototype’s IR sensor bar communicates via the Gamecube memory card port. The auction listing featured a photo size comparison of the prototype sensor bar is around four inches wider than the final design. Missing from the prototype Wii remote is the small tinny speaker, but that always seemed like an after thought anyway.

Credence as to the controller’s validity was given in a tweet from WayForward’s James Montagna who said on Twitter, “Wow, it’s the prototype Wii Remote & Nunchuk! I remember seeing these back when it was still known as the Nintendo Revolution!”. Montagna would go on to post photos of the Wii remote from E3 2006 that featured ‘Back’ and ‘Pause’ buttons where the plus and minus buttons would ultimately reside on the final design. These photos of the missing links in the evolution of the Wii remote help fill in the design process at Nintendo. They also further the idea that Nintendo always wanted players to measure each of their new consoles’ processing power in “X number of Gamecubes duct taped together”.

This Isn’t The R2-D2 Controller You’re Looking For

July 19, 2017 by 7 Comments

Who loves a good R2-D2 robot? Everyone, but especially young Star Wars fans who — frustratingly — have no problem spotting a controller and spoiling the illusion of an R2 unit brought to life. [Bithead942]’s concealed his R2-D2’s remote and re-establishes the illusion of an autonomous droid — no Jedi mind-tricks necessary.

[Bithead942] prefers to accompany his droid in traditional a Rebel Alliance pilot’s suit, so that gives him a bit of extra space under the jumpsuit to help conceal the controller. Dismantling a Frsky Taranis X9D controller, [Bithead942] meditated on how to use it while so concealed. In a stroke of insight, he thought of his unused Wiimote nunchucks, and launched into the build.

We Dig This LEGO Excavator Conversion

July 4, 2017 by 16 Comments

[Frank] was lucky enough to score a bucket wheel excavator LEGO set as a birthday present, and we won’t lie – we’re jealous. However, out of the box, the kit is somewhat limited; there is only one motor to animate the entire machine and it can’t be fully remote controlled. But don’t worry — [Frank] set out to change that (Google Translation).

The first part of the build was to add motors to control the different functions of the excavator. One motor was added for each of the two tracks to allow the machine to drive forwards, backwards, and turn. Two more motors were added to raise and lower the digging buckets, and spin the tower. Finally, the original motor was left in place to turn the conveyor.

With that done, [Frank] then used a Raspberry Pi 3 to control all the hardware, being sure to house the new electronics in LEGO for an original look. The Raspberry Pi might be a lot of muscle to simply control a few motors, but it made it quick and easy for [Frank] to implement a Wiimote as a controller over Bluetooth. You can check out a couple demo videos in his most recent update.

It’s a great project, and we’d love to see the Raspberry Pi put to good use by allowing control over the Internet so we can dig in the sand over lunch breaks. We’ve seen some great LEGO hacks before, like this method of modifying cheap gear motors to work with LEGO parts.

Interfacing A Retro Controller Using The USBASP

June 22, 2017 by 7 Comments

An ISP dongle is a very common piece of equipment on a maker’s bench. However, its potential as a hackable device is generally overlooked. The USBASP has an ATmeg8L at its heart and [Robson] decided that this humble USB device could be used as an interface between his PC and a SNES Joypad.

A SNES controller required three pins to communicate with a host: clock, data and latch. In his hack, [Robson]  connects the controller to the ISP interface using a small DIY adaptor and programs the AVR using the V-USB library. V-USB is a software USB library for small microcontrollers and comes in pretty handy in this instance.

[Robson] does a pretty good job of documenting the entire process of creating the interface which includes the USB HID code as well as the SNES joypad serial protocol. His hack works on both Windows and Linux alike and the code is available on GitHub for download.

Simple implementation like this project are a great starting point for anyone looking to dip their toes in the DIY USB device pool. Veterans may find a complete DIY joystick more up their alley and will be inspired by some plastic techniques as well.
