2024 Tiny Games Contest: Realistic Steering Wheel Joystick In Miniature

August 30, 2024 by 4 Comments

For racing games, flight simulators, and a few other simulation-style games, a simple controller just won’t do. You want something that looks and feels closer to the real thing. The major downsides to these more elaborate input methods is that they take up a large amount of space, requiring extra time for setup, and can be quite expensive as well. To solve both of these problems [Rahel zahir Ali] created a miniature steering wheel controller for some of his favorite games.

While there are some commercial offerings of small steering wheels integrated into an otherwise standard video game controller and a few 3D printed homebrew options, nothing really felt like a true substitute. The main design goal with this controller was to maintain the 900-degree rotation of a standard car steering wheel in a smaller size. It uses a 600P/R rotary encoder attached to a knob inside of a printed case, with two spring-loaded levers to act as a throttle and brake, as well as a standard joystick to adjust camera angle and four additional buttons. Everything is wired together with an Arduino Leonardo that sends the inputs along to the computer.

Now he’s ready to play some of his favorite games and includes some gameplay footage using this controller in the video linked below. If you’re racing vehicles other than cars and trucks, though, you might want a different type of controller for your games instead.

Take Control Of MS Flight Sim With Your Smartphone

June 1, 2024 by 3 Comments

Anyone with more than a passing interest in flight simulators will eventually want to upgrade their experience with a HOTAS (Hands On Throttle-And-Stick) setup that has buttons and switches for controlling your virtual aircraft’s assorted systems, which are well supported by games such as Microsoft Flight Simulator (MSFS). But a traditional HOTAS system can be a bit of an investment, so you might want to thank [Vaibhav Sharma] for the virtualHOTAS project that brings a configurable HOTAS interface to your phone — just in time to try out that Dune expansion for MSFS.

The phone’s orientation sensors are used as a joystick, and on the screen, there’s both sliders and buttons you can use as in-game controls. On the back-end there’s a Python program on the computer which exposes a webserver that the phone connects to, translating sensor and press data without the need for an app. This works wonderfully in MSFS, as [Vaibhav] shows us in the video below. What’s more, if you get tired of the touchscreen-and-accelerometer controls, you can even connect a generic smartphone-designed game controller platform, to have its commands and movements be translated to your PC too!

All the code is open source, and with the way this project operates, it will likely work as a general-purpose interface for other projects of yours. Whether you might want to build an accessibility controller from its codebase, use it for your robot platform, maybe simply repurpose this project for any other game, [Vaibhav]’s creation is yet another reminder that we’re carrying a sensor-packed platform, and it might just help you build a peripheral you didn’t know you needed.

Don’t have a phone handy? Perhaps an Xbox controller could work with just a few 3D printed upgrades, or you could stock up on buttons and build your own joystick from scratch. Oh, and keeping HOTAS principles in mind can be pretty helpful — you might get to redesign the venerable computer mouse, for instance!

Wico Boss Joystick Modded To Use Cherry MX Keyboard Switches

March 22, 2024 by 5 Comments

The Wico Boss joystick was one of the better designs of the 1980s. Yours truly had one, and put it through many brutal hours of Amiga-based gameplay. [Drygol] was recently asked if he could alter some of these sticks to be even clickier than stock, and jumped at the change to do some modding.

[Drygol]’s idea was to swap out the original microswitches in the sticks for keyboard switches instead. In particular, the idea was to use the Cherry MX Blues which have a particularly nice click to them. But this wasn’t just going to be a straight swap. Instead, since the hardware was retro and preservation was desired, the modification had to be reversible.

The result was a drop-in 3D-printed bracket that holds four Cherry switches around the joystick’s central bauble. Thus, when the stick is moved, it actuates the keyboard switches with a satisfying click. A 12mm tactile switch was also installed in the base to be activated by the fire button. Then, it was a simple matter of  tidying up some of the sticks during reassembly and wiring up the original cables to the new switches.

It’s a neat way to give an old-fashioned digital joystick a new lease on life. This would be a particularly great mod for tired sticks with worn out microswitches, too. Hilarious archaic marketing video after the break. They really are whacko for Wico.

Hall Sensors Offer Drop-In Replacement For Drifting Game Console Joysticks

May 24, 2023 by 44 Comments

No bananas were harmed in the making of this Hall effect drift-proof joystick replacement. OK, not really — two bananas were turned to mush. But it’s OK, they’re just bananas, after all.

Why bananas, you ask? Because [Marius Heier] uses them to demonstrate what we all intuitively know — that rubbing something over and over again tends to wear it away — but engineers seem to have forgotten. Wear such as this, with resistance material rather than fruits, is what causes the dreaded drift, a problem that the world collectively spends $20 billion a year dealing with, according to [Marius].

While numbers like that seem to be firmly in class-action lawsuit territory, sometimes it’s best to take matters into your own hands and not wait for the courts. The fix [Marius] shows here is to yank the potentiometers off a PS4 joystick and replace them with contactless Hall effect sensors. The end of the shaft for each axis gets a diametral neodymium magnet attached to it, while a 3D printed bracket holds a tiny custom PCB in close proximity. The PCB has an AS5600 Hall sensor, which translates the shaft angle to an analog voltage output. After programming the chip over its I2C bus, the sensor outputs a voltage proportional to the angle of each shaft, just like the original pots, but without all the wear and tear.

While [Marius] is selling these as drop-in replacements for PS4 controllers, he plans to release all the design files so you can build one yourself. He also has his sights set on replacements for PS5 and Xbox controllers, so watch for those. This isn’t his first foray into joystick hacking, having shared his 3D Hall effect and haptic feedback joysticks with us previously.

A 4-Player Arcade Hidden Inside A Coffee Table

May 11, 2023 by 3 Comments

[Ed] from 50% Awesome on YouTube wanted to build a retro gaming system with a decent screen size, but doesn’t have a great deal of space to site it in, so a good compromise was to make a piece of useful furniture and hide all the fun parts inside.

Building an arcade machine usually involves a lot of wiring

This video two-part build log shows a lot of woodwork, with a lot of mistakes (happy accidents, that are totally fine) made along the way, so you do need to repeat them. Essentially it’s a simple maple-veneered plywood box, with a thick lid section hosting the display and some repositioned speakers. This display is taken from a standard LG TV with the control PCB ripped out. The power button/IR PCB was prised out of the bezel, to be relocated, as were the two downwards-facing speakers. The whole collection of parts was attached to a front panel, with copious hot glue, we just hope the heavy TV panel was firmly held in there by other means!

Autopsy Of A Drifting Thumbstick Reveals All

April 12, 2023 by 34 Comments

Analog sticks have become a core part of modern video game controllers. They also routinely fail or end up drifting, consigning expensive controllers to the garbage. [sjm4306] recently did a repair job on an Oculus VR gaming controller with drifting analog sticks, and decided to do an autopsy to figure out what actually went wrong.

A microscope reveals gouges in the resistive material, caused by the metal contacts inside the analog stick. This happened via regular use.

The video starts by taking apart the analog joystick itself by prying off the metal case. Inside, we get a look at the many tiny individual components that make up a modern thumbstick. Of most interest, though, are the components that make up the potentiometers within the stick. Investigation revealed that the metal contacts that move with the stick had worn through the resistive coating on the thin plastic membrane in the base of the joystick, creating the frustrating drift problem.

It doesn’t have to be this way. Analog sticks in modern controllers could be manufactured with higher-quality components that don’t wear so easily. After all, it’s hard to imagine a 90s video game controller wearing out as fast as this modern Oculus unit. But everything is built to a price, at the end of the day, and that’s just how it goes. Video after the break.

Fresh PCBs For The Quickshot II And II Plus Joysticks

March 21, 2023 by 13 Comments

The Quickshot II was released by Spectravideo in 1983 for the Commodore 64 and compatible systems, with the Quickshot II Plus following the next year. After decades of regular use, it’s quite understandable that these old-timers may be having some functional issues, but as long as the plastic parts are still good, [Stephan Eckweiler]’s replacement PCBs may be just the thing that these joysticks need to revitalize them for another few decades.

What may be a matter of taste is that these replace the nice tactile clicky switches on the QS II Plus with SMD push buttons, but compared to the stamped metal ‘button’ construction of the original QS II, the new board is probably a major improvement. As for the BOM, it features two ICs: a 74LS00 latch and NE555 timer, along with the expected stack of passives and switches, both through-hole and SMD.

The PCB contains break-off boards for the switches within the joystick itself, requiring a bit of wiring to be run to the main PCB before soldering on the DE-9 connector and connecting the joystick for a test run to a Commodore 64. All one needs now is a 3D printable enclosure version to create more QS II joysticks for some multiplayer action.
