Mods Keep The WaveBird Kicking In The Switch Era

April 13, 2019 by Tom Nardi 11 Comments

Nintendo made some questionable decisions during the early 2000’s, but developing the WaveBird certainly wasn’t one of them. Years before wireless controllers were the standard on home game consoles, the WaveBird gave GameCube owners a glimpse into the future. It managed to deliver lag-free gaming without resorting to easily-blocked infrared, and had a battery life and range long enough that there was really no downside to cutting the cord aside from the lack of rumble support.

In fact, the WaveBird was such a good controller that some fans just can’t put the thing down even in 2019. [Bill Paxton] loves his so much that he decided to modify it so he could use it on Nintendo’s latest money printing machine, the Switch, without having to fiddle with any adapters. While he was at it, he decided to fix the only serious drawback of the controller and hack in some rumble motors; arguably making his re-imagined WaveBird superior in just about every way to the original.

It might be counter-intuitive, but the trick here is that [Bill] actually took the internals from a standard wired GameCube controller and fitted it all into the case for the WaveBird. That’s how he got the rumble support back, but where does the signature wireless capability come from?

For that, he took apart a “GBros. Wireless Adapter” from 8BitDo. This gadget is intended to let you use your existing GameCube controllers on the Switch wirelessly, so all he had to do was shove its PCB inside the controller and wire it directly to the pads on the controller’s board. Thankfully, the WaveBird was rather husky to begin with, so there’s enough space inside to add all the extra hardware without much fuss.

Between modifications like this and efforts to reverse engineer the controller’s wireless protocol, hackers aren’t about to let this revolutionary accessory go gently into that good night. You might see a GameCube slaughtered for a meme, but WaveBirds never die.

Wireless Controllers For Retro Gaming

April 8, 2019 by Bryan Cockfield 5 Comments

There’s no limit to the amount of nostalgia that can be minted through various classic platforms such as the NES classic. The old titles are still extremely popular, and putting them in a modern package makes them even more accessible. On the other hand, if you still have the original hardware things can start getting fussy. With modern technology it’s possible to make some changes, though, as [PJ Allen] did by adding wireless capabilities to his Commodore 64.

Back when the system was still considered “modern”, [PJ] tried to build a wireless controller using DTMF over FM radio. He couldn’t get it to work exactly right and ended up shelving the project until the present day. Now, we have a lot more tools at our disposal than analog radio, so he pulled out an Arduino and a few Bluetooth modules. There’s a bit of finesse to getting the old hardware to behave with the modern equipment, though, but once [PJ] worked through the kinks he was able to play his classic games like Defender without the limitations of wired controllers.

The Commodore 64 was incredibly popular in the ’80s and early ’90s, and its legacy is still seen today. People are building brand new machines, building emulators for them, or upgrading their hardware.

Drone Gives Up Its Wireless Secrets To Zigbee Sniffer

February 8, 2019 by Dan Maloney 2 Comments

There’s something thrilling about decoding an unknown communications protocol. You start with a few clues, poke at the problem with some simple tools, and eventually work your way up to that first breakthrough that lets you crack the code. It can be frustrating, but when you eventually win, it can be very rewarding.

It seems that [Jason] learned this while decoding the wireless conversation between his mass-market quad and its controller. The quad in question, a Yuneec Q500, is one of those mid-range, ready-to-fly drones that’s targeted at those looking to get in the air easily and take some cool pictures. Unsure how the drone and controller were talking, [Jason] popped the covers and found a Zigbee chipset within. With the help of a $14 Zigbee USB dongle and some packet sniffing software from TI, [Jason] was able to see packets flowing, but decoding them was laborious. Luckily, the sniffer app can be set up to stream packets to another device, so [Jason] wrote a program to receive and display packets. He used that to completely characterize each controller input and the data coming back from the drone. It’s a long and strange toolchain, but the upshot is that he’s now able to create KML in real time and track the drone on Google Earth as it flies. The video below shows the build and a few backyard test flights.

Congratulations to [Jason] for breaking the protocol and opening up drones like this for other hackers. If you’re interested in learning more about Zigbee sniffing, you can actually hack a few smarthome gadgets into useful sniffers.

Use Your 360 Controllers On The Original Xbox

February 8, 2019 by Lewin Day 17 Comments

Microsoft’s original Xbox was regarded curiously by gamers and the press alike at launch. It was bigger, bulkier, and featured an eldritch monstrosity as its original controller. Thankfully, Microsoft saw fit to improve things later in the console’s lifespan with the Controller S, but nothing quite compares to the simple glory of the Xbox 360 controller. Now, there’s a way to use one on your original Xbox.

This project is the work of [Ryzee119], who previously adapted the controller for use with the Nintendo 64. An Arduino Pro Micro, acting as a master controller, talks to a MAX3421 USB host controller, which interfaces with an Xbox 360 wireless receiver, either genuine or third-party. The Arduino reads the data from the wireless receiver and then emulates a standard controller to the original Xbox. The system can handle up to four players on wireless 360 controllers, requiring an extra Arduino per controller to act in slave mode and emulate the signals to the original Xbox. In testing, lag appears roughly comparable with an original wired controller. This is a particularly important consideration for fast-paced action games or anything rhythm based.

It’s a well executed, fully featured project that should improve your weekly Halo 2 LAN parties immensely. No more shall Greg trip over a controller cable, spilling Doritos and Mountain Dew on your shagpile carpeting. Video after the break.

RC Controller Becomes XInput Controller

January 5, 2019 by Lewin Day 4 Comments

XInput is an API that is used by applications to interface with the Xbox 360 Controller for Windows. The 360 controller became somewhat of a “standard” PC gamepad, and thus many games and applications support the XInput standard.

[James] is working on an entry for a robotics competition, and wanted a controller to use with their PC that was more suited to their build. They took an RC controller, and converted it to work with XInput instead.

The controller in question is the JJRC Q35-01, a trigger-type RC controller available for under $20. The conversion is executed neatly, with the original STM microcontroller being removed from the board, and the PCB traces instead being connected to a Teensy 3.5 which takes over running the show.

The conversion is remarkably complete, with the team not stopping at just reading the buttons and steering potentiometer. A USB logic analyzer was used to figure out how to control the LCD, and a calibration mode implemented just in case.

[James] has shared the work on Github so it’s reproducible for the average maker. We’ve seen plenty of builds in this space, like this tilt controller from [Electronoobs]. Video after the break.

Replace Legacy CNC PCs With A Gerbil

December 4, 2018 by Bryan Cockfield 48 Comments

There are lots of laser cutters and other CNC machines available for a decent price online, but the major hurdle to getting these machines running won’t be the price or the parts. It’s usually the controller PC, which might be running Windows XP or NT if you’re lucky, but some of them are still using IBM XT computers from the ’80s. Even if the hardware in these machines is working, it might be impossible to get the software, and even then it will be dated and lacking features of modern computers. Enter the Super Gerbil.

[Paul] was able to find a laser cutter with one of these obsolete controllers, but figured there was a better way to getting it running again. As the name suggests, it uses GRBL, a G-Code parser and CNC controller software package that was originally made to run on an 8-bit AVR microcontroller, but [Paul] designed the Super Gerbil to run on a 32 bit ARM platform. He also added Z-axis control to it, so it now sports more degrees of freedom than the original software.

By way of a proof of concept, once he was finished building the Super Gerbil he ordered a CNC machine from China with an obsolete controller and was able to get it running within a day. As an added bonus, he made everything open so there are no license fees or cloud storage requirements if you want to use his controller. [Paul] also has a Kickstarter page for this project as well. Hopefully controllers haven’t been the only thing stopping you from getting a CNC machine for your lab, though, but if they have you now have a great solution for a 3040 or 3020 CNC machine’s controller, or any other CNC machine you might want to have.

SNES Controller Has A Pi Zero In The Trunk

November 17, 2018 by Tom Nardi 7 Comments

We’re no stranger to seeing people jam a Raspberry Pi into an old gaming console to turn it into a RetroPie system. Frankly, at this point it seems like we’ve got to be getting close to seeing all possible permutations of the concept. According to the bingo card we keep here at Hackaday HQ we’re just waiting for somebody to put one into an Apple Bandai Pippin, creating the PiPi and achieving singularity. Get it done, people.

That being said, we’re still occasionally surprised by what people come up with. The Super GamePad Zero by [Zach Levine] is a fairly compelling take on the Pi-in-the-controller theme that we haven’t seen before, adding a 3D printed “caboose” to the stock Super Nintendo controller. The printed case extension, designed by Thingiverse user [Sigismond0], makes the controller about twice as thick, but that’s still not bad compared to modern game controllers.

In his guide [Zach] walks the reader through installing the Raspberry Pi running RetroPie in the expanded case. This includes putting a power LED where the controller’s cable used to go, and connecting the stock controller PCB to the Pi’s GPIO pins. This is an especially nice touch that not only saves you time and effort, but retains the original feel of the D-Pad and buttons. Just make sure the buttons on your donor controller aren’t shot before you start the build.

Adding a little more breathing room for your wiring isn’t the only reason to use the 3D printed bottom, either. It implements a very clever “shelf” design that exposes the Pi’s USB and HDMI ports on the rear of the controller. This allows you to easily connect power and video to the device without spoiling the overall look. With integrated labels for the connectors and a suitably matching filament color, the overall effect really does look like it could be a commercial product.

The SNES controller is an especially popular target for hacks and modifications. From commercially available kits to the wide array of homebrew builds, it there’s plenty of people who want to keep this legendary piece of gaming gear going strong into the 21st century
