Patience Beats Rage-Quit In Shattered Xbox Controller Repair

September 19, 2020 by 18 Comments

There are negative-one hacks to this project. Someone lost at their game, lost their temper, then raged at their Xbox controller with some horsepower. The result is that [Taylor Burley] gets a free controller with a non-responsive joystick out of the deal, and since he had nothing to lose, he decided to heat up the iron and bring the controller back to life.

The majority of the project is told in pictures and through the narration in the video below. In removing the joystick, [Taylor] opts for the technique of doping the connections with fresh solder (we assume containing lead for easier melting) before reaching for the desoldering wick. The diagnosis stage is brief because when the joystick lifts away, the PCB falls apart into two separate pieces! The next step was to glue the two halves together with cyanoacrylate to get into the nooks and crannies, then epoxy to provide structure. Solder bridges were not going to jump that gap, so he used 30ga wire and attached it wherever he could scrape away some solder mask. Best of all, it worked when he reattached the joystick. Job well done.

Xbox controllers are not a scarce commodity, so people do not spend their idle hours fixing them, but not many people can claim experience. Maybe someday the stakes will be higher and he will have the courage to repair vintage electronics. We won’t rant on how things aren’t built to last, and how we don’t train people to fix things. Today, we want to focus on someone who used their time to repair and learn.

Life Size Lancer Becomes Gears Of War Motion Controller

July 20, 2020 by 3 Comments

Gears of War is a franchise famous for its giant gun with a big chainsaw on the front. [Eric] laid his hands on a toy replica, and decided it had to become a usable motion controller for the game.

The build is straightforward, following the usual format for motion controller builds. Fitted with a gyroscope and accelerometer, it’s interfaced to the PC using a microcontroller. The toy has a trigger which is hooked up to the fire button in game. Additional buttons were added to the shell for movement and other actions such as reloading and finding cover. As a nice final touch, the large pull handle on the left of the weapon is used to activate the chain saw in-game.

While it’s unlikely to be competitive with a mouse or even gamepad in practice, it’s hard to argue against the fun of wielding a full-size, 10-pound weapon when playing Gears of War 5. [Eric] has also shared a basic controller hacking guide for those eager to get into similar builds themselves. We’ve featured [Eric]’s work before, too – with this epic Minecraft pickaxe build. Video after the break.

Super Mario 64 As Experienced By Mario

July 16, 2020 by 4 Comments

Microsoft’s Kinect, a motion-sensing peripherial originally for the Xbox 360, is almost exactly a decade old now. And in that decade it has expanded from its limited existence tied to a console to a widely-used tool for effective and detailed motion sensing, without breaking the bank. While it’s seen use well outside of video games, it’s still being used to reimagine some classic games. In this project, Reddit user [SuperLouis64] has used it to control Mario with his own body.

While the build still involves some use of a hand controller, most of Mario’s movements are controlled by making analogous movements on a small trampoline, including the famed triple jump. The kinect is able to sense all of these movements and translate them into the game using software that [SuperLouis64] built as well. The trickiest movement seems to be Mario’s spin movement, which appears to have taken some practice to get right.

We appreciate the build quality on this one, and [SuperLouis64]’s excitement in playing the game with his creation. It truly looks like a blast to play, and he even mentions in the Reddit thread that he’s gotten a lot of productive excercise with his various VR and augumented reality games in the past few months. Of course if this is too much physical activity, you could always switch to using your car as the unique game controller instead.

Control A Motor With A Touchpad

June 10, 2020 by 11 Comments

There are a surprising wealth of parts inside of old laptops that can be easily scavenged, but often these proprietary tidbits of electronics will need a substantial amount of work to make them useful again. Obviously things such as hard drives and memory can easily be used again, but it’s also possible to get things like screens or batteries to work with other devices with some effort. Now, there’s also a way to reuse the trackpad as well.

This build uses a PS/2 touchpad with a Synaptics chip in it, which integrates pretty smoothly with an Arduino after a few pins on the touchpad are soldered to. Most of the work is done on the touchpad’s built in chip, so once the Arduino receives the input from the touchpad it’s free to do virtually anything with it. In this case, [Kushagra] used it to operate a stepper motor in a few different implementations.

If you have this type of touchpad lying around, all of the code and schematics to make it useful again are available on the project page. An old laptop in the parts bin is sure to have a lot of uses even after you take the screen off, but don’t forget that your old beige PS/2 mouse from 1995 is sure to have some uses like this as well.

Run Your Favorite 8-bit Games On An ESP32

June 9, 2020 by 20 Comments

Here at Hackaday HQ we’re no strangers to vintage game emulation. New versions of old consoles and arcade cabinets frequently make excellent fodder for clever hacks to cram as much functionality as possible into tiny modern microcontrollers. We’ve covered [rossumur]’s hacks before, but the ESP_8-bit is a milestone in comprehensive capability. This time, he’s topped himself.

There isn’t much the ESP 8-bit won’t do. It can emulate three popular consoles, complete with ROM selection menus (with menu bloops). Don’t worry about building a controller, just connect any old (HID compliant) Bluetooth Classic keyboard or WiiMote you have at hand. Or if that doesn’t do it, a selection of IR devices ranging from joysticks from the Atari Flashback 4 to Apple TV remotes are compatible. Connect analog audio and composite video and the device is ready to go.

The system provides this impressive capability with an absolute minimum of components. Often a schematic is too complex to fit into a short post, but we’ll reproduce this one here to give you a sense for what we’re talking about. Come back when you’ve refreshed your Art of Electronics and have a complete understanding of the hardware at work. We never cease to be amazed at the amount of capability available in modern “hobbyist” components. With such a short BOM this thing can be put together by anyone with an ESP-32-anything.

There’s one more hack worth noting; the clever way [rossumur] gets full color NTSC composite video from a very busy microcontroller. They note that NTSC can be finicky and requires an extremely stable high speed reference clock as a foundation. [rossumur] discovered that the ESP-32 includes a PLL designed for audio work (the “APLL”) which conveniently supports fractional components, allowing it to be trimmed to within an inch of the desired frequency. The full description is included in the GitHub page for the project and includes detailed background of various efforts to get color NTSC video (including the names of a couple hackers you might recognize from these pages).

Slide Your Switch Into A Gamecube Controller

May 2, 2020 by 7 Comments

The Gamecube was certainly a divisive design when it was released back in 2001, but the fact that people are still happily hacking away at its controller nearly 20 years later proves that Nintendo must have gotten something right. The latest project from Nintendo wizard [Bill Paxton] turns the unique Gamecube controller into an even more unique mobile dock for the Switch.

To build this “Gamecube Grip”, [Bill] literally cut an original controller and its PCB in half so they could be relocated on either end of the 3D printed central frame. Internally, the controller PCB is wired up to a GC+ board, which is an open hardware project that uses a PIC18F25K22 microcontroller to bring enhanced features to the classic peripheral such as adjustable stick dead zones and rumble intensity. From there, it’s connected to the switch with a GBros adapter from 8bitdo.

The grip also includes an Anker PowerCore 20,100 mAh battery that should keep the system going for hours, and some components liberated from a third party Switch dock. Everything has been finished off with the attention to detail that we’ve come to expect from [Bill] and his projects, including the seemingly flawless glossy paint job that’s something of hallmark for his custom gaming creations.

Putting An Arcade Cabinet Inside Of An NES Controller

May 1, 2020 by 23 Comments

The arcade game shoehorned into an original Nintendo Entertainment System controller from [Taylor Burley] is certainly made slightly easier by its starting with one of those miniature cabinets that are all the rage now, but since he’s still achieved the feat of an entire arcade game in a controller we still stand by the assessment in our title.

In fact, he’s put not one but four arcade games into the controller. The board that [Taylor] liberated from the miniature game system can actually be switched between the onboard games by shorting out different pads on the PCB. Normally this would be done during manufacture with a zero-ohm resistor, but in this case, he’s wired the pads out to a strip of membrane keypad liberated from an LED remote control. By holding a different button while powering on the system, the user can select which of the games they want to boot into.

The original buttons and directional pad have been preserved, and in the video after the break, [Taylor] shows how he wires them into the arcade PCB. The Start and Select buttons had to go since that’s where the tiny color LCD goes now, but they wouldn’t have been used in any of these games anyway. With the addition of a small battery pack and charge controller, this build is a clever way to take several classic arcade titles with you on the go.

With the growing popularity of these tiny arcade cabinets, we’ve seen a number of hackers tearing into them. The work that [wrongbaud] has done in modifying them to run other ROMs is not to be missed if you’re looking at building a project using one of these little bundles of nostalgia.
